Sausage Breakfast Casserole – Dinners, Dishes & Desserts

Sausage Breakfast Casserole – a super easy make-ahead sausage egg casserole with hash browns, breakfast sausage, green peppers and lots of cheese! Perfect for brunch or when you have a full house!

I love having a good casserole breakfast on the weekends, for the holidays, or when we have a house full of people. They’re so good to make ahead and ready to pop in the oven when you wake up in the morning!

This sausage egg bake is probably our favorite, it’s so simple, with all the components you want. Potatoes, eggs, sausages and cheese. I add bell pepper and onion for extra flavor, but you can skip that or even add more!

A traditional American breakfast that feeds a crowd! This recipe relies on frozen hash browns and lots of eggs for a hearty and easy breakfast. One of the great things about a breakfast casserole is that you can put everything together ahead of time! So when you wake up in the morning, all you have to do is cook it…no need to brown the meat or stir early in the morning.

One of my other favorites is this Crockpot Breakfast Casserole because it literally cooks while you sleep, so you wake up with breakfast ready!

  1. Using a large skillet, brown the breakfast sausage, chopped peppers and onions for 5-6 minutes, breaking into small pieces, until lightly browned, cooked through and the vegetables are tender.

  3. In a large bowl, beat together eggs, milk, salt and pepper until very well blended. Pour evenly over sausage mixture.
  4. Sprinkle cheese on top. Cover with foil.
  5. You can now cook immediately or place in the fridge overnight to cook in the morning.

If you want to make it the day before, follow the recipe up to the cooking instructions. Cover with aluminum foil and place in the refrigerator for up to 24 hours. Then cook in the morning according to the instructions below.

Can I freeze a breakfast casserole

Yes you can. To freeze the breakfast casserole, follow the recipe and when you cover it with foil, simply place it in the freezer for up to 3 months. When you’re ready to do so, let it thaw in the fridge overnight. I like to let it sit on the counter for about an hour before baking as well, to make sure everything in the center is thawed and about the same temperature. Then you can cook according to the recipe instructions.

Can I use anything other than sausages for breakfast?

Absolutely! You can use any meat you prefer. Diced ham, chopped bacon, even tempeh or other plant-based alternatives work great. Diced ham that you wouldn’t need to cook ahead of time, so just saute your onions and peppers until soft, then toss everything together to arrange over the potatoes.

Leftovers can be stored in an airtight container for up to 4 days in the refrigerator. You can microwave individual slices or cover with foil and reheat in a 350º oven until warmed through.

This Sausage Egg Casserole makes a lot, so if you have a small family or don’t want a lot of leftovers, you can definitely cut the recipe in half and bake in an 8-inch square pan.

How to serve

This sausage breakfast casserole is great on its own, you have potatoes, eggs and cheese so it is very filling. But if you want to supplement, here are some good options.
