Creating Tater Tot Breakfast Casserole is simple if you follow these steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C).
2. Cook the Meat: In a skillet over medium heat, cook the breakfast sausage or bacon until browned. Drain excess fat and set aside.
3. Prepare the Egg Mixture: In a large bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and onion powder until well combined.
4. Layer the Casserole: In a greased 9×13-inch baking dish, layer half of the tater tots on the bottom.
5. Add Meat and Veggies: Spread the cooked sausage or bacon over the tater tots. If using, add chopped vegetables next.
6. Pour Egg Mixture: Carefully pour the egg mixture evenly over the layered ingredients.
7. Top with Cheese: Sprinkle the remaining tater tots on top, followed by the shredded cheese.
8. Bake: Place the casserole in the preheated oven and bake for 45-50 minutes, or until the eggs are set and the top is golden brown.
9. Cool and Serve: Once finished, remove it from the oven and let it cool for about 5-10 minutes before slicing.
