Instructions
Prepare the Beef
Preheat your oven to 400°F (200°C). Lightly grease a 9x13-inch baking dish.
In a large skillet over medium-high heat, cook the ground beef and diced onion together, breaking the beef into small crumbles, until the meat is fully browned and the onion is soft, about 8-10 minutes.
Drain the excess grease from the skillet. Season the beef with garlic powder, onion powder, salt, black pepper, and paprika. Stir well and cook for one more minute to let the spices bloom.
Make the Special Sauce
In a small mixing bowl, stir together the mayonnaise, yellow mustard, ketchup, dill pickle relish, white vinegar, garlic powder, onion powder, and sugar until smooth and well combined.
Assemble the Casserole
Spread the seasoned ground beef in an even layer in the bottom of the prepared baking dish.
Scatter the chopped dill pickles evenly over the beef layer.
Drizzle about half of the special sauce over the beef and pickles.
Sprinkle the shredded cheese evenly over the sauce layer.
Arrange the frozen tater tots in a single, tight layer over the cheese, covering the entire surface.
Bake
Bake uncovered at 400°F for 30-35 minutes, until the tater tots are deep golden brown and crispy and the cheese is bubbling around the edges.
Remove from the oven and let rest for 5 minutes. Drizzle the remaining special sauce over the top, sprinkle with sesame seeds and shredded iceberg lettuce. Serve immediately.
