Preheat the oven to 350°F. Prepare your 2-quart baking dish with oil or cooking spray.
In a large skillet over medium heat, cook the ground beef with diced onion and red peppers until the beef is browned. Drain off the excess grease. Turn off the heat. 1 lb Ground Beef½ cup Yellow Onion1 Red Bell Pepper
Stir in ketchup, mustard, diced dill pickles, salt, pepper, paprika, and garlic powder. Mix well to combine flavors. Spoon this mixture into the prepared casserole dish and smooth it into an even layer. ⅔ cup Ketchup2 tablespoon Yellow Mustard¼ cup Dill Pickles½ teaspoon Salt½ teaspoon Black Pepper½ teaspoon Garlic Powder½ teaspoon Paprika
Make Cheese Sauce
In a saucepan, melt butter over medium heat. Whisk in flour and cook for about one minute to create a roux. 2 tablespoon Butter2 teaspoon All-Purpose Flour
Slowly whisk in the milk and cook until the sauce thickens, about 5 minutes. Stir in salt and pepper. 1½ cups Milk¼ teaspoon Salt¼ teaspoon Black Pepper
Remove pan from heat and stir in 1 ½ cups cheese until it is completely melted and the sauce is smooth. 1½ cups Cheddar Cheese
Pour the cheese sauce over the top and spread evenly.
Bake Casserole
Arrange frozen tater tots in a single layer over the casserole. (You may have extra tots) 32 oz Tater Tots
Bake in a preheated oven for 35 minutes. Remove from the oven and sprinkle the remaining ½ cup of cheese over the top. Return to the oven for an additional 5 minutes or until the cheese is melted. ½ cup Cheddar Cheese
Notes
Even layer of tots - This ensures they get crispy instead of steaming.
Shred your own cheese - Pre-shredded cheese contains anti-caking agents that can make the sauce less smooth.
Cook the Roux long enough - Let the butter and flour cook for about a minute to eliminate the raw flour taste.
Let the casserole rest before serving - Allowing it to sit for a few minutes helps it set up and makes slicing easier.
Don't thaw the tater tots - Use them straight from the freezer so they bake up crispy on top.
