Cheesy Hashbrown Casserole Ingredients

How to Make Breakfast hashbrown casserole
Spray a 13×9 baking dish with nonstick spray. We want to cook the hashbrowns a little bit first to prevent them from getting soggy. By cooking them first we’re going to keep them crisp. Spread hashbrowns out on the bottom of the dish, sprinkling some salt and pepper on top. Now, bake them in the oven.

While the hashbrowns are cooking, brown the sausage in a skillet with diced onion and green pepper. This smells so good!

By this time your hashbrowns should be crispy and you can remove them from the oven. Add the browned sausage mixture on top of the hashbrowns, spreading it evenly around.

Break eggs into a large bowl and beat.

Add milk, cheddar cheese and tomatoes into the bowl and stir.

Pour the egg mixture on top of the sausage, using a spatula to even it out.

Cover with aluminum foil and bake. Then remove the foil and cook for a little longer. This is going to make a perfectly baked casserole! Once it’s pulled from the oven, allow a few minutes to cool down and set and then cut into slices to serve!

Make ahead breakfast casserole
Prepare the casserole per recipe, skipping the 20 minute bake time in the beginning for the hashbrowns. Allow to cool and then cover and store in the refrigerator. When ready to make it, bake for around 45 minutes covered and 30 minutes uncovered. You might need to add 10-15 extra minutes since it’ll be cold coming from the refrigerator.
