KEY INGREDIENTS

Hashbrowns: I used shredded hashbrowns that I found in the frozen section at my grocery store but you can use cubed hashbrowns or hashbrown patties. You can either defrost the hashbrowns or put them in frozen. 

Eggs: you’ll need 8 whole eggs. The eggs are mixed with milk that creates a fluffy egg mixture that binds all the ingredients together. 

Sausage: I use crumbled breakfast or Italian sausage. Try to pat out as much grease as you can before adding it to your casserole. You can also use your favorite sausage links and just cut them up. Other great meat options are diced ham and cooked bacon.

Cheese: I love using sharp cheddar cheese as it adds the most flavor and compliments the other ingredients. Other cheeses to use instead of or use a combination of Monterey Jack cheese, Colby, or Swiss. Really, any cheese will work perfectly!

HOW TO MAKE THIS HASHBROWN BREAKFAST CASSEROLE

RECIPE TIPS & VARIATIONS

Other meat protein options to add in or use instead of sausage are crumbled bacon, chorizo, ground beef, turkey bacon, and diced ham.

It’s important to cook the sausage or any other meat protein ahead of time. Make sure that it’s completely cooked through and try to pat out as much excess grease as you can.

I always recommend shredding your own cheese yourself so it’s extra melty. The pre-shredded stuff works but it’s just not the same and an anti-caking agent is always added so it prevents the cheese from melting and takes away from the flavor of the cheese. 

If you want your hashbrowns to be crispy, simply brown them in a skillet before layering the ingredients. Try to remove as much excess fat as possible before adding it to the casserole.

This casserole could be made vegetarian by omitting the sausage and adding extra veggies such as zucchini, mushrooms, fresh spinach, and tomatoes. 

WHY THIS BREAKFAST CASSEROLE WORKS

Super easy: This couldn’t be any easier to make and takes minutes to prepare. Browning the sausage takes the most time and that only takes a few minutes. This truly is effortless to put together!

Feeds a crowd: This casserole feeds a crowd so it’s perfect for brunches or you can meal prep this so you have breakfast ready for the week. Everyone will love this delicious and hearty casserole.

Easily customized: you can customize this recipe to your liking and preference. You can use your favorite veggies, cheese, and proteins. 

MAKE-AHEAD

This is the perfect breakfast casserole to make if you are wanting to prep this and make it the day or night before. There are a few options that you can do to make it ahead.

Bake Now and Reheat Later: bake the casserole according to the instructions. Once the casserole is completely cooked, cover with foil and place in the refrigerator until ready to reheat. When ready to reheat, leave the foil on and bake at 350 degrees for 10-15 minutes, or until warm.

Assemble and Bake Later: assemble the casserole according to the instructions. Cover with foil and place in the refrigerator until ready to bake. You can do this the night before so all you have to do in the morning is pop the casserole in the oven. 

LEFTOVERS & STORAGE

To Store: cover the casserole tightly with plastic wrap and place in the refrigerator for up to 3-4 days. Reheat in the microwave or oven when ready to eat.
