Making Cheeseburger Tater Tot Casserole is straightforward if you follow these easy steps:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C).
2. Brown the Beef: In a large skillet over medium heat, cook the ground beef along with the diced onion and minced garlic. Stir occasionally until the beef is browned and onions are soft.
3. Season the Mixture: Add salt and black pepper to the beef mixture. Stir well to combine.
4. Add Cream of Mushroom Soup: Pour in the cream of mushroom soup and milk, mixing until fully incorporated. This creates a creamy base.
5. Add Cheese: Stir in the shredded cheddar cheese until it melts into the mixture.
6. Transfer to a Casserole Dish: Spoon the beef and cheese mixture into a greased 9×13-inch casserole dish, spreading it evenly.
7. Top with Tater Tots: Place the frozen tater tots on top of the beef mixture in a single layer.
8. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes or until the tater tots are golden and crispy.
9. Add Pickles and Condiments: If desired, add chopped dill pickles, ketchup, and mustard on top of the casserole after it finishes baking.
10. Cool and Serve: Allow the casserole to cool for a few minutes before serving. This will make it easier to scoop out portions.

These simple steps will guide you to creating this flavor-packed casserole that is sure to please everyone at the table.
