Tomato Paste

Storage Guide

"A tiny can with more flavor per penny than anything in your pantry."

That little 6-ounce can is the most underrated powerhouse in a budget kitchen. Tomato paste is concentrated sunshine — deep, rich, umami flavor that turns a pot of cheap beans or a skillet of ground beef into something that tastes like it simmered all day. And at 50 cents a can, there's no excuse not to keep a dozen on hand.

Preservation Methods

Year-round supply

Culinary Add 2 tablespoons to a hot skillet with olive oil and cook for 1-2 minutes until it darkens — this caramelizes the sugars and deepens the flavor before adding other ingredients

Culinary Stir 1 tablespoon into a pot of rice as it cooks for a West African-style jollof base — adds color, richness, and depth

Culinary Whisk 2 tablespoons into beef stew, chili, or soup to thicken the broth and boost tomato flavor without adding a whole can of sauce

Culinary Mix 1 tablespoon into ground beef or turkey while browning for tacos, sloppy joes, or pasta sauce — it disappears into the meat and adds richness

Culinary Spread a thin layer on pizza dough or flatbread as a quick sauce — no cooking needed, just spread, top, and bake

Culinary Stir a tablespoon into scrambled eggs or an omelet for a shakshuka-inspired breakfast flavor

Culinary Dissolve 2 tablespoons in 1 cup of warm water with a pinch of salt and Italian seasoning for an emergency pizza or pasta sauce

Culinary Add a tablespoon to pot roast, braised chicken, or slow cooker meals in the last hour for a richer, more complex gravy

Culinary Mix into meatloaf or meatball mixtures — 2 tablespoons per pound of meat adds moisture and flavor from the inside out

Culinary Whisk a tablespoon into homemade salad dressings or vinaigrettes for body and a tomato backbone

Garden Dilute expired tomato paste heavily in water and use to water acid-loving plants like blueberries, azaleas, or hydrangeas

Garden Add small amounts to the compost bin — the tomato solids break down quickly and add nutrients to the pile

Household Rub a thin layer of tomato paste on tarnished copper-bottom pans, let sit 10 minutes, then scrub and rinse — the acid dissolves the tarnish naturally

Household Apply to tarnished brass hardware or decorative items, wait 15 minutes, wipe clean with a damp cloth and buff dry

Culinary Scoop tablespoon-sized portions onto a parchment-lined baking sheet and freeze — once solid, transfer to a zip-top bag. Pull out exactly what you need for the next 6 months

Culinary Mix leftovers with equal parts softened butter and a pinch of garlic salt for a compound butter that's incredible on steak, grilled bread, or baked potatoes

Culinary Stir into a pot of cooking dried beans for extra body and flavor — kidney beans, black beans, and pintos all love it

Culinary Whisk leftover paste into gravy or pan drippings for a richer, more complex sauce

Culinary Spread on bread with a little olive oil, garlic, and Italian seasoning, then toast for a quick bruschetta base

Garden If too old to eat, scrape into the compost — tomato paste breaks down fast and adds acidity to a pile that's too alkaline

Household Use expired paste for copper and brass polishing — no sense wasting good paste, but the old stuff cleans just as well

Culinary Use the clean empty can as a biscuit cutter or small round cookie cutter — the size is perfect for tea biscuits

Garden Poke drainage holes in the bottom and use as starter pots for seeds — tomato paste cans are the perfect size for seedlings before transplanting

Garden Cut both ends off and press into the soil around young transplants as a cutworm collar to protect stems

Garden Bury a can with the top rim at soil level and fill with beer to trap slugs in the garden

Household Use as small storage containers for screws, nails, buttons, and small hardware in the garage or craft room

Household Clean thoroughly and use as a candle mold — pour melted wax with a wick, let set, and peel the can away

Culinary Squeeze a ribbon directly into soups, stews, and sauces — no measuring, no leftover can, no waste. The tube lasts for weeks in the fridge.

Culinary Squeeze a thin line onto grilled cheese sandwiches before closing — it adds a subtle savory depth between the cheese layers

Culinary Squeeze directly into marinades for a concentrated tomato hit without adding extra liquid

Culinary Dot small amounts onto roasted vegetables — eggplant, zucchini, and mushrooms — in the last 10 minutes of roasting for concentrated flavor bursts

Garden When the tube is truly empty, cut it open — there's always a tablespoon or two stuck inside. Scrape into compost or dissolve in water for plants.

Household Cut open the empty tube, flatten, and use the residual paste to polish a small copper item — get every last bit of use

💡 Grandmaw's Tips

🌱 Always bloom tomato paste in hot oil or fat for 1-2 minutes before adding liquid. This caramelizes the sugars and removes the raw, tinny taste. It's the single biggest upgrade you can make to your soups and stews.

🌱 Tomato paste is NOT tomato sauce. Paste is concentrated — a little goes a long way. If a recipe calls for sauce and you only have paste, mix 1 part paste with 2 parts water.

🌱 A tablespoon of tomato paste in your chili, stew, or soup adds more depth than an entire can of diced tomatoes. Think of it as a flavor amplifier, not a tomato ingredient.

🌱 If you want to make your own, roast halved Roma tomatoes cut-side down at 300°F for 3-4 hours, then blend and strain. It freezes beautifully.

🌱 Tomato paste is rich in lycopene, which is actually more available to your body from cooked and concentrated tomatoes than from raw ones.

Here's how to keep tomato paste all year long.

🧊 Frozen Tablespoon Dollops

6-12 months

Best for: Portioned, ready-to-use paste for soups, stews, and sauces

💡 This is the trick every budget cook needs. Spoon tablespoon-sized blobs onto parchment, freeze solid, bag them up. You'll never waste half a can again.

🫙 Refrigerator Storage (Tube)

6-8 weeks

Best for: Small-batch cooking where you need a tablespoon at a time

💡 The tube costs a little more upfront but pays for itself in zero waste. Cap it tight and store in the fridge door.

📦 Pantry Stockpile (Unopened Cans)

3-5 years

Best for: Emergency meals, pantry staple, always-have-it-on-hand cooking

💡 At 50 cents a can, buy a dozen at a time. Stack them in your pantry and you'll never be caught without flavor.

🧊 Ice Cube Tray Freezing

6-12 months

Best for: Smaller portions for rice dishes, scrambled eggs, and quick sauces

💡 Fill each well of an ice cube tray with paste, freeze, pop them out, and bag them. Each cube is about a tablespoon.

🫙 Oil-Topped Jar Storage

2-3 weeks (refrigerated)

Best for: When you want to use the opened paste over a couple weeks without freezing

💡 Transfer leftover paste to a small jar and pour a thin layer of olive oil on top. The oil seals out air and the paste stays fresh much longer.

☀️ Homemade Dehydrated Tomato Powder

1-2 years

Best for: Seasoning blends, dry rubs, instant flavor boosts

💡 Spread paste thin on a parchment-lined sheet and dehydrate at 135°F until brittle. Grind to powder. One teaspoon in anything tastes like summer.
