Creating this incredible Chili Cheese Tater Tot Casserole is easy if you follow these steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).

2. Cook the Meat: In a large skillet over medium heat, cook the ground beef (or turkey) until browned. Drain excess fat.

3. Add Beans and Tomatoes: Stir in the kidney beans, black beans, chili beans, diced tomatoes, and taco seasoning. Mix well to combine the flavors.

4. Simmer: Let the mixture simmer for about 5-10 minutes. This allows the flavors to meld beautifully.

5. Layer the Casserole: In a large baking dish, spread the meat and bean mixture evenly across the bottom.

6. Add Cheese: Sprinkle 1 cup of shredded cheddar cheese over the meat mixture, distributing it evenly.

7. Add Tater Tots: Layer the frozen tater tots on top of the cheese, ensuring they cover the entire surface.

8. More Cheese: Top the tater tots with the remaining cup of shredded cheddar cheese.

9. Bake: Place the baking dish in the preheated oven and bake for 40-45 minutes, or until the tater tots are golden and crispy.

10. Cool Down: Once finished, remove the casserole from the oven and allow it to cool for 5-10 minutes before serving.

11. Serve: Scoop out generous portions and serve hot, garnishing with sour cream and chopped green onions if desired.

By following these steps, you’ll create a tater tot casserole that is not only easy to make but also incredibly satisfying.
