Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with cooking spray or butter.

In a large skillet over medium heat, cook the ground sausage until fully browned and crumbled. Drain any excess fat and set aside to cool slightly.

In a mixing bowl, whisk together the eggs, milk, salt, and pepper until smooth. Add optional spices like paprika or garlic powder if desired.

Spread a layer of frozen tater tots evenly across the bottom of the greased baking dish. Sprinkle the cooked sausage over the tater tots, followed by any optional vegetables you’re adding.

Pour the egg mixture evenly over the sausage and tater tots. Top with shredded cheese.

Bake in the preheated oven for 35-40 minutes, or until the eggs are set, the cheese is melted and bubbly, and the tater tots are golden brown and crispy.

Let the casserole rest for 5-10 minutes before slicing. Garnish with fresh herbs like parsley or chives if desired, and serve with optional toppings such as sour cream, salsa, or avocado slices.
