Instructions

Preheat the Oven: Set your oven temperature to 350°F (175°C) and allow it to fully preheat as you prepare the casserole ingredients.
Brown the Sausage: Crumble the sausage into a skillet over medium heat. Cook thoroughly, breaking it up with a spatula, until browned and cooked through. Remove from heat and set aside.
Prepare the Egg Mixture: In a large bowl, crack the eggs and whisk them together with the milk until well combined. Stir in the salt and pepper for even seasoning throughout the mixture.
Assemble the Casserole: In a 9×13-inch baking dish, add the frozen hashbrowns, cooked sausage, and shredded cheddar cheese. Stir gently in the dish to distribute everything evenly.
Add Egg Mixture: Pour the prepared egg and milk mixture evenly over the casserole ingredients, ensuring that the liquid soaks evenly throughout.
Bake the Casserole: Cover the dish with foil and bake in the preheated oven for 45 minutes.
Finish Baking: Remove the foil and continue baking for an additional 10–15 minutes, or until the casserole is bubbly and the cheese on top is melted and starting to turn golden.

Notes

Substitute sausage with bacon or vegetarian sausage for variation.
You can prepare the casserole ahead and refrigerate overnight; bake fresh in the morning.
Mix in vegetables like bell peppers, onions, or spinach for extra flavor and nutrition.
Let the casserole rest for 5–10 minutes before slicing for the best texture.
