Ingredients

1 pound lean ground beef
1 medium onion, chopped
1 green bell pepper, chopped
3/4 cup tomato ketchup
1 teaspoon yellow mustard
1 teaspoon garlic powder
1 teaspoon smoked paprika
1/2 teaspoon crushed red pepper flakes (optional)
1 teaspoon Worcestershire sauce
1/2 teaspoon white vinegar
1/2 cup beef broth or water
2 cups cheddar, grated
32 ounces frozen tater tots (see note)
Salt & pepper, to taste

Instructions

Preheat the Oven:
Preheat your oven to 375°F and position the rack in the top third of the oven.
Cook the Beef:
In a skillet, brown the ground beef over medium-high heat, breaking it apart with a spoon. This should take about 10 minutes. Drain excess fat if needed (especially if not using lean beef).
Add Vegetables:
Stir in the chopped onion and green bell pepper. Cook for 5 minutes, stirring occasionally, until softened.
Make the Sauce:
Reduce heat to medium and mix in the ketchup, mustard, garlic powder, smoked paprika, crushed red pepper flakes (if using), Worcestershire sauce, vinegar, and beef broth. Stir well and simmer for 2-3 minutes until heated through. Avoid letting the mixture become too dry.
Assemble the Casserole:
Transfer the beef mixture to a 9×13-inch casserole dish, spreading it evenly. If using an oven-safe skillet, you can skip this step and assemble in the skillet.
Layer with Cheese:
Sprinkle one cup of grated cheddar evenly over the beef mixture.
Add Tater Tots:
Arrange the tater tots on top in a single layer.
Bake:
Bake the casserole, uncovered, for 45 minutes until the tater tots are golden and crispy.
Add Final Cheese Layer:
Sprinkle the remaining cup of cheddar on top and return the dish to the oven for 5 minutes, or until the cheese is melted.
Serve:
Season with extra salt and pepper if needed. Serve hot and enjoy!

Yes, sliced or diced potatoes can be used, but they may require par-cooking before layering to ensure they cook through.
