Easy Hash Brown Breakfast Casserole
I am a huge fan of make-ahead egg dishes for Christmas morning or simply to enjoy for breakfast all week long. Hands down this sausage hashbrown breakfast casserole is one of my family’s all-time favorites.
While I love this breakfast meatballs recipe with a side of eggs for a savory breakfast, this casserole recipe is a classic combination of it all with sausage, frozen hashbrowns, eggs, and cheese in one bite.
It’s delicious, efficient, and a great way to serve a crowd without a lot of fuss!
Why This Recipe Works
- Make ahead. Prep it the night before, store in the fridge and bake the next morning into eggy, cheesy perfection.
- Customizable. Add some veggies or you swap out the protein and use whatever you have on hand.
- Convenience. Overnight egg casseroles like this one or my strata recipe save time on busy mornings while delivering a big flavor.
Breakfast Casserole Recipe Ingredients
A handful of simple and easy-to-find ingredients are all you need to make this hearty egg and hashbrown casserole.
Find the full printable recipe with specific measurements below.
- Breakfast sausage: I used 1 pound of pork sausage. You can buy just the sausage meat or sausages in casings, just be sure to remove the meat from the casing before cooking it.
- Frozen shredded hash browns: These are usually in the frozen aisle by the French fries. There’s no need to thaw them out first before browning them in the skillet. You can also make your own hash browns if can’t find the frozen ones.
- Cheese: I use a blend of shredded sharp cheddar cheese and Monterey jack but feel free to use all cheddar or even throw in some mozzarella.
- Seasoning: Garlic powder, salt, and pepper are all I add. If you’d like to throw in some hot pepper flakes, or seasoning salt, go for it!
Substitutions and Variations
- For a different flavor, you can use sage sausage and Gruyere cheese.
- Swap the sausage for turkey sausage, diced ham, or bacon crumbles. Leftover roasted turkey or baked ham work, too!
- Leave the meat out altogether for a vegetarian option like this cheesy hashbrown casserole.
- For a little kick, add a few dashes of hot sauce and red pepper flakes to the eggs.
- Throw in some sauteed vegetables such as onions, bell peppers, or mushrooms or even spinach like I do in my crockpot breakfast casserole recipe!
How to Make Hashbrown Breakfast Casserole
A few minutes of prep is all you need to assemble this easy sausage hashbrown breakfast casserole. Let’s go through the steps!
- Brown sausage and hashbrowns. Cook sausage meat in a skillet then set the meat aside and brown the hashbrowns.
- Beat the eggs. Crack the eggs into a large bowl and beat them together then whisk in the milk, garlic powder, and seasoning.
- Assemble. Sprinkle the browned hashbrowns over the bottom of a 9×13-inch casserole dish then top with the sausage. Spread shredded cheese evenly over the sausage and finally pour the egg mixture over the top of everything.
- Bake. The casserole should bake uncovered for 35 – 40 minutes. Remember to let it cool for a few minutes before serving.
Make Ahead
The beauty of breakfast casseroles is that they can be prepped the day before and then baked in the oven the following morning. They’re perfect for busy mornings or a special holiday breakfast!
All you have to do is assemble the hashbrown breakfast casserole with sausage, cover the dish, and refrigerate it for up to 12 hours. Then the next morning, uncover the dish, pop it in the oven, and bake. The perfect fuss-free breakfast!
Expert Tips
- Make it creamier. For a creamier egg custard, swap the 2% milk for whole milk or half and half.
- Brown the hashbrowns. Browning your hashbrowns in a skillet first makes them crispy and gives your casserole a little extra crunch.
- Top browning too quickly? Cover the hashbrown casserole with sausage using a piece of aluminum foil to finish baking if it looks like the top is browning too quickly.
Recipe FAQs
If you follow the recipe directions, your hashbrown casserole with sausage shouldn’t dry out, but if you’re worried about it, cover the dish with foil for the first half of baking and then remove it to let the casserole brown.
The great thing about this recipe is that you don’t have to defrost the hashbrowns first before you add them to the pan to cook. You can throw them in while still frozen and brown them in the pan.
I usually insert the tip of a knife into the center of the casserole and if it comes out wet, then I pop it back into the oven for a few minutes.
Storing + Reheating
Store: This breakfast hashbrown breakfast casserole with sausage will keep in the refrigerator for up to 3 days. Store the entire casserole or individual servings in an airtight container.
To reheat: Microwave individual pieces on a microwave-safe plate for about 1 minute. To make your pieces crispy, reheat them in the toaster oven or the air fryer. To reheat the entire casserole, cover the dish with foil and put the whole thing back into the oven at 350°F for 20 – 30 minutes until heated through.
