Creating Cowboy Casserole is a breeze when you follow these simple steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).
2. Brown the Beef: In a large skillet, brown the ground beef over medium heat until fully cooked. Drain the excess fat.
3. Mix Soups and Milk: In a bowl, combine the cream of mushroom soup, cream of chicken soup, and milk. Stir until well mixed.
4. Season the Mixture: Add onion powder, garlic powder, salt, and pepper to the soup mixture. Stir well.
5. Combine Ingredients: In the skillet with the beef, pour the soup mixture and half of the shredded cheddar cheese. Stir until all ingredients are combined.
6. Prepare the Dish: Transfer the beef and soup mixture into a greased 9×13 inch baking dish.
7. Layer Tater Tots: Evenly spread the frozen tater tots over the top of the casserole.
8. Bake: Place the casserole in the preheated oven and bake for 30 minutes.
9. Add Cheese: After 30 minutes, remove the casserole from the oven. Sprinkle the remaining cheddar cheese on top.
10. Finish Baking: Return the dish to the oven and bake for an additional 15 minutes, or until the tater tots are golden brown and the cheese is bubbly.
11. Cool and Serve: Once done, let the casserole cool for a few minutes before serving.

These straightforward steps will help you create a Cowboy Casserole that is not only delicious but also visually appealing!
