Creating Tater Tot Casserole with Ground Beef is an easy process if you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Brown the Beef: In a large skillet over medium heat, brown the ground beef along with the diced onions until the beef is fully cooked. Drain any excess grease.
3. Add Garlic: Stir in the minced garlic and cook for an additional minute until fragrant.
4. Combine Ingredients: In a large mixing bowl, add the cooked beef mixture, cream of mushroom soup, sour cream, salt, and pepper. Mix well until smooth.
5. Incorporate Cheese: Fold in the shredded cheddar cheese, ensuring it’s evenly distributed throughout the mixture. You can add mixed vegetables at this stage if desired.
6. Assemble the Casserole: Transfer the beef mixture into a greased 9×13-inch casserole dish, spreading it evenly across the bottom.
7. Top with Tater Tots: Arrange the frozen tater tots in a single layer on top of the beef mixture.
8. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes, or until the tater tots are golden brown and crispy.
9. Serve: Once baked, allow it to cool slightly before serving, so the casserole sets up perfectly.
