I have baked in ovens that cost more than my first car, and I have baked in ovens that came with a house built in 1962. I have used convection fans and I have used plain old radiant heat, and I will tell you right now — the oven matters less than you think, but the differences matter more than most people realize. When it comes to Southern baking, where a biscuit needs to rise fast and a pecan pie needs to set without burning, understanding what your oven is actually doing in there is the difference between something beautiful and something you scrape into the trash.
This is not about which oven is better. That is the wrong question. The right question is which oven does what, and when do you want each one working for you. I have spent decades figuring that out, and I am going to walk you through every bit of it — from biscuits to cobblers to pound cakes — so you know exactly what to expect from whatever oven is sitting in your kitchen right now.
If you are setting up a kitchen for the first time or thinking about upgrading, you will also want to read Building a Southern Kitchen on a Budget: The 5 Essential Tools because the oven is just one piece of the puzzle. But it is an important piece, and it deserves a real conversation.
What a Conventional Oven Actually Does
A conventional oven is what most of us grew up with. It has a heating element on the bottom — and sometimes one on top for broiling — and that is it. The heat radiates up from the bottom, and the air inside the oven gets hot. But here is the thing most people do not think about: that air is not moving. It just sits there, and that means the temperature inside a conventional oven is not the same everywhere.
The bottom of the oven is hotter than the top. The back corners tend to run hotter than the front. If you have ever pulled out a sheet of cookies and noticed the ones in the back are darker than the ones in the front, that is your oven telling you it has hot spots. Every conventional oven has them, and once you learn where yours are, you can work with them instead of fighting them.
I learned my first oven’s personality within a month of moving into my house. The back left corner ran hot, so I always rotated my pans halfway through. That is not a flaw — that is just how conventional ovens work. You learn to adjust. You peek, you rotate, you pay attention. That is what baking is.
Conventional ovens also hold moisture better than convection ovens because the air is not being pushed around and dried out. That matters more than you might think, especially for things like custard pies and cakes that need a gentler environment to set properly.
What a Convection Oven Actually Does
A convection oven has the same heating elements, but it adds a fan — sometimes two — that circulates the hot air around the inside of the oven. That moving air does two things. First, it evens out the temperature so you do not get those hot spots I just mentioned. Second, it pushes heat onto the surface of your food more aggressively, which means things brown faster and cook faster.
Think of it this way. If you stand outside on a cold day and the air is still, you can handle it for a while. But the second the wind picks up, that same temperature feels a whole lot colder. That is exactly what convection does, except with heat. The moving air transfers energy to your food faster than still air does.
Now, that sounds like a good thing, and sometimes it is. Roasting a chicken? Convection is wonderful. Those sheet pan dinners I talk about in Sheet Pan Southern Dinners: 10 Recipes for Easy Weeknights? Convection can give you beautiful, even browning. But when it comes to baking — real Southern baking — that fan can cause problems if you do not know how to handle it.
The 25-Degree Rule and Why It Exists
The most common advice you will hear about convection baking is to reduce your temperature by 25 degrees from whatever the recipe calls for. If a recipe says 425 degrees, you set your convection oven to 400. That is the standard rule, and it is a reasonable starting point, but I want you to understand why it exists so you can make smart decisions instead of just following a number.
Because that fan is pushing hot air directly onto your food, the effective cooking temperature is higher than what the dial says. Your biscuits do not care what number is on the display — they care about how much heat is actually hitting them. In a convection oven at 425, your biscuits are experiencing something closer to 450, and that is enough to burn the tops before the insides are done.
The 25-degree reduction gets you back into the range your recipe was designed for. But I will tell you honestly, some of my recipes need a full 30 or even 35 degrees lower in convection, and some only need 15. It depends on the dish, the pan, and how your particular oven’s fan behaves. This is where paying attention matters more than following rules.
Biscuits: Where the Difference Matters Most
Biscuits are where this conversation gets personal for me. I have been making biscuits since I was tall enough to reach the counter, and I will tell you that a conventional oven is my first choice for biscuits every single time. Here is why.
A biscuit needs intense bottom heat to get that golden crust on the underside, and it needs the top to stay just slightly cooler for the first few minutes so the layers have time to rise before the outside sets. In a conventional oven, that happens naturally. The bottom element pushes heat up, the biscuit starts rising from the steam created by that cold butter hitting hot air, and by the time the top starts browning, the inside structure has already set.
In a convection oven, that fan hits the top of the biscuit with heat immediately. The outside can start to crust over before the inside has had a chance to rise fully, and you end up with a shorter, denser biscuit that looks golden but does not have those tall, flaky layers you are after. If you have been struggling with your biscuits, I talk about what makes them work in Perfect Southern Biscuits: A Step-by-Step Guide, and understanding your oven is a big part of that.
Now, can you make good biscuits in a convection oven? Yes, you can. But you need to drop that temperature down, and you might want to start them on a lower rack to give the bottoms a head start before the fan does its work on the tops. Some people put them in with the convection fan off for the first five minutes, then turn it on to finish browning. That works too, if your oven lets you do it mid-bake.
Cornbread: A Different Story Entirely
Cornbread is interesting because it actually does well in both types of ovens, but for different reasons. In a conventional oven, you get that classic method — you preheat your Cast Iron Cooking: The Southern Way|cast iron skillet in the oven, pour in your batter, hear that beautiful sizzle, and the bottom crust forms from the direct contact with that screaming hot iron. The rest of the cornbread bakes from the surrounding heat, and you get a cake that is crispy on the bottom and edges and tender in the middle.
In a convection oven, you still get that sizzle from the hot skillet, but the fan also gives you more even browning on top. The result is cornbread that is a little more uniformly golden all over, which some people prefer. You do lose a tiny bit of that contrast between the crispy bottom and the softer top, but it is not a dramatic difference.
Where it matters is with Cornbread Variations: Skillet, Sweet, Savory, and Cracklin’ that have more sugar or fat in them. Sweet cornbread can brown too fast on the edges in convection, so watch it carefully. Cracklin’ cornbread does fine either way because those pork cracklings create their own little pockets of fat and flavor that are not much affected by the air circulation.
Pies: Custard, Fruit, and Pecan — Each One Different
Pies are where you really need to think about what is happening inside your oven, because different types of pies need different things.
A fruit pie — like a blackberry cobbler or a deep-dish apple pie — does beautifully in convection. The circulating air helps the top crust brown evenly and get that flaky, golden look, and the filling is wet enough that it is not going to dry out from the fan. If anything, convection helps fruit pies because it sets the bottom crust faster, which means less chance of a soggy bottom. That alone makes it worth trying.
Custard pies are a completely different situation. A chess pie, a buttermilk pie, a sweet potato pie — these are delicate. The filling is a custard that needs to set gently and evenly, and the fan in a convection oven can cause the surface to set and crack before the center has firmed up. I always bake my custard pies in a conventional oven, no exceptions. The gentle, still heat lets the custard cook from the edges inward at its own pace, and you end up with a smooth, silky top instead of one that looks like a dry lake bed.
Pecan pie falls somewhere in between. The filling has enough sugar and corn syrup to handle some airflow, but the pecans on top can burn if the convection fan is pushing too much heat at them. If you bake pecan pie in convection, drop the temperature and keep a loose sheet of foil nearby to tent the top if those pecans start getting too dark. I go deeper into getting pecan pie right in How to Make a Perfect Pecan Pie Without it Being Too Sweet.
The pie crust itself — and I talk about this in How to Make a Flaky Pie Crust: The Lard vs. Butter Debate — benefits from a hot start to set the fat and create flakiness. Convection can help with that initial blast, but for the long, slow bake that most Southern pies need, conventional is more forgiving.
Cakes and Pound Cakes: Slow and Steady
If there is one category of Southern baking where I will put my foot down and say use a conventional oven, it is cakes. Especially pound cake.
A The Classic Southern Pound Cake: A Complete Guide|Southern pound cake is a dense, buttery cake that needs a long, even bake to cook all the way through without the outside getting too dark. It relies on a steady, predictable environment to rise slowly and set from the outside in. A convection fan disrupts that. It can cause the top to crust over too quickly, which traps steam inside and creates a gummy layer just under the surface. It can also cause uneven rising, where one side of the cake domes higher than the other because the fan is hitting it from one direction.
Layer cakes have the same issue. When you are baking two or three thin layers at the same time, convection can cook the one closest to the fan faster than the others, and you end up with layers that are different textures. In a conventional oven, as long as you rotate them once halfway through, they come out even.
The one exception I will make is for sheet cakes. Because a sheet cake is thin and wide, it bakes quickly and the convection fan actually helps it brown evenly across that big surface. But for a Bundt cake, a tube cake, or anything with real depth to it — keep that fan off.
The Real Truth About Oven Thermometers
I do not care if your oven is convection, conventional, or powered by burning logs in the backyard — you need an oven thermometer. I cannot say this strongly enough. The temperature your oven dial says and the temperature your oven actually is are rarely the same thing. I have seen ovens off by 25 degrees. I have seen them off by 50.
Hang a good oven thermometer from the center rack and check it against what your dial says. If there is a difference, write it on a piece of tape and stick it to the oven so you always remember. My oven runs about 15 degrees hot, so when I set it to 375, I know I am really getting close to 390, and I adjust accordingly. That little four-dollar thermometer has saved me more heartache than I can count.
This matters even more with convection because you are already reducing the temperature by 25 degrees. If your oven also runs hot by 20 degrees, you are now 45 degrees over what you intended, and that is the difference between a golden biscuit and a burned one. Know your oven. That is the first and most important rule in Southern Oven Cooking: A Master Guide to Times & Temperatures, and it applies to everything I am talking about here.
When Convection Shines in a Southern Kitchen
I do not want to make it sound like convection is the enemy of Southern baking. It is not. There are plenty of things it does beautifully, and if you have a convection oven, you should be using it for those things.
Roasting vegetables for a side dish — convection is wonderful. That hot, moving air caramelizes the edges of squash, sweet potatoes, and okra in a way that still air just cannot match. If you are making Perfect Okra: A Guide to Frying, Stewing & Roasting in the oven, convection will give you crispier edges and less sogginess.
Roasting a whole chicken or a turkey — convection gives you that beautiful, evenly golden skin all over. No more worrying about rotating the bird halfway through because one side is browning faster than the other. The fan does that work for you.
Anything that benefits from a dry, crispy exterior — fried chicken you are reheating, sheet pan dinners, roasted root vegetables, even bacon in the oven — convection is your friend. It pulls moisture away from the surface faster than still air, and that is exactly what you want for crispiness.
The air fryer craze is really just small convection ovens, and I talk about that in Air Fryer Southern Cooking: A Complete Guide to Crispy Classics. The principle is the same — circulating hot air creates a crisper exterior. The air fryer just does it in a smaller space with a more powerful fan.
When to Turn the Fan Off
Most modern convection ovens let you turn the fan on or off. Some even let you choose between full convection and a gentler setting that slows the fan speed. If your oven has those options, use them. Here is my general guide based on years of burning things and learning from it.
Turn the fan off for biscuits during the first half of baking, then you can turn it on at the end if you want more browning on top. Turn it off for custard pies the entire time — chess pie, buttermilk pie, sweet potato pie, pumpkin pie. Turn it off for pound cakes, Bundt cakes, and any cake with real depth. Turn it off for angel food cake, which needs still air to rise properly in the tube pan. Turn it off for soufflés and anything egg-based that could crack or deflate from the air pressure.
Turn the fan on for fruit pies after the first fifteen minutes, once the crust has had a chance to set. Turn it on for roasting meats and vegetables. Turn it on for reheating anything fried. Turn it on for sheet cakes and thin, flat baked goods where even browning matters more than rise.
And if you are not sure? Start with the fan off. You can always turn it on later to finish browning. You cannot undo what it has already done.
Rack Position Matters More Than You Think
In a conventional oven, where you put your rack changes everything. The bottom third of the oven is the hottest zone and gives you the most bottom heat — that is where your cornbread skillet goes, and where your pie goes if you want to set the bottom crust. The center of the oven is your all-purpose spot for cakes and biscuits, where the heat is most even. The top third is where you finish things — where you put the broiler on for a minute to brown the top of a casserole or get the last bit of color on a cobbler.
In a convection oven, rack position matters less because the fan is equalizing the temperature. But it still matters some. I still start my cornbread on a lower rack even in convection, because I want that skillet close to the heat source for the best crust. And I still keep delicate things like custard pies in the center, because even with a fan, the edges of the oven can run slightly hotter.
The biggest mistake I see people make is putting two sheet pans in a conventional oven on different racks and expecting them to bake the same. They will not. The one on the lower rack will brown on the bottom faster, and the one on the upper rack will brown on top faster. You have to rotate them — swap their positions — halfway through. Convection helps with this problem significantly, but it does not eliminate it completely.
Preheating: Why It Is Not Optional
I do not care which type of oven you have — you must preheat it fully before anything goes in. Most ovens beep or show a light when they think they have reached temperature, but I have tested enough of them to know that the oven is rarely actually at the set temperature when that signal goes off. Give it another ten minutes after the preheat signal. That extra time lets the heat soak into the walls, the racks, and the air so that when you open the door and slide in your biscuit pan, the oven recovers its temperature quickly.
This is especially important in conventional ovens because they recover from a door opening more slowly than convection ovens. Every time you open that door, you lose 25 to 50 degrees of heat. In a conventional oven, it can take several minutes to get back to temperature. In a convection oven, the fan pushes hot air back around faster, so recovery is quicker. But either way, do not stand there with the door open admiring your biscuits. Peek quickly and close it.
For things like cornbread where you need a preheated skillet, I put the cast iron in the oven at the start of preheating and let it come up to temperature right along with the oven. By the time everything is fully preheated, that skillet is screaming hot and ready for the batter. That technique does not change between convection and conventional — it works the same in both.
Converting Recipes Between Oven Types
Most Southern recipes — the ones handed down on index cards and written in the margins of church cookbooks — were written for conventional ovens. If you are using a convection oven to bake from those recipes, here is what I have learned works.
Start with the 25-degree reduction. If the recipe says 400, set your convection oven to 375. Check whatever you are baking five to eight minutes before the recipe says it should be done. Do not rely on the timer alone — use your eyes and your nose. When a biscuit looks right and your kitchen smells like butter and flour, it is probably close regardless of what the clock says.
For things with a long bake time, like a pound cake that goes for an hour or more, the time reduction can be significant — sometimes ten to fifteen minutes less. For quick-baking things like biscuits that only need twelve to fifteen minutes, you might only shave off two or three minutes. The longer something bakes, the more time you save with convection.
If you are going the other direction — converting a convection recipe to a conventional oven — add 25 degrees and expect to add a few minutes to the baking time. And remember those hot spots. In a conventional oven, you need to rotate your pans. In convection, you probably do not.
What I Use and Why
I have a conventional oven that I have been using for more years than I care to admit, and I know every inch of it. I know where the hot spots are, I know it runs about 15 degrees hot, and I know that the door does not seal as tight as it used to, which means it loses heat a little faster than it should. I have thought about getting a convection oven, and I probably will someday, but I will tell you this — there is nothing wrong with a conventional oven for Southern baking. Generations of the best biscuits, pies, cakes, and cornbread this country has ever seen came out of conventional ovens, and they will continue to.
If you have convection, learn how to use it well. Turn the fan off when you need to, reduce your temperatures, and watch your baking more carefully until you learn how your particular oven behaves. If you have conventional, do not let anyone tell you that you need to upgrade. You do not. You just need to know your oven and respect what it does.
The tools matter, but the hands and the eyes and the nose of the person using them matter more. That is true for ovens, and it is true for every piece of equipment I talk about in The Complete Guide to Southern Cooking: Techniques, Traditions & Time-Tested Wisdom. The best oven in the world will not make good biscuits for someone who does not pay attention, and a fifty-year-old oven with a temperamental thermostat will turn out something beautiful for someone who has taken the time to learn it.
I have burned more things than I can count learning what I know about ovens. Every burned biscuit, every cracked pie, every pound cake with a gummy streak taught me something. The oven is not just a box that makes things hot — it is a tool with a personality, and the sooner you learn its personality, the sooner everything you bake starts turning out the way it should. Do not fight your oven. Learn it. Work with it. And when something goes wrong, pay attention to what it is trying to tell you, because it is always telling you something.
That is the kind of knowledge that does not come from a manual or a spec sheet. It comes from standing in front of that oven a thousand times and noticing what happens. And that, more than any fan or heating element, is what makes someone a good baker.
