What is a hash brown casserole?
A hash brown casserole is a breakfast casserole that is is filled with hash browns, eggs, sausage, bell peppers and topped with shredded cheese. This egg casserole can be served for breakfast, brunch or even dinner.
Can I substitute any of the ingredients?
Yes, you can use your favorite ingredients in this baked egg dish.
- Swap diced ham for the sausage
- Use cooked diced bacon instead of sausage
- Choose your favorite type of cheese
- Omit the red bell pepper, if you don't care for it

If you are looking for another type of egg casserole, you might want to look at my cheesy baked eggs, or this ham and cheese strata.
Steps to make
Spray a 9 x 13 inch baking dish with nonstick cooking spray. Place potatoes in the bottom of the dish. 
Add cooked sausage and chopped bell peppers.
Combine eggs, milk, mustard, red pepper flakes and salt and pepper in a bowl. 
Pour egg mixture over potatoes
Top with cheese
Place on a baking sheet and bake in a preheated 375 degree oven for 1 hour.
How do I know if it's done?
Give the casserole a little jiggle. If it doesn't move in the center insert a knife in the center to verify it being cooked through. The knife should come out clean with no raw egg on it.
Can I make ahead of time?
Yes, you can make this breakfast casserole ahead of time. Place all ingredients in the casserole dish and cover with foil. Refrigerate overnight. Remove from refrigerator at least 30 minutes before baking. Increase baking time by 15 minutes.
Can I freeze this dish?
I would not recommend freezing this dish unbaked. You could however, freeze it once it is baked. Leftovers can also be refrigerated and reheated in the microwave.
Tips on making hash brown casserole
- You can purchase a 20 ounce bag of ready to cook hash brown potatoes or you can make your own
- Use whole milk or 2% milk
- Use a blend of shredded cheese - cheddar and Monterey Jack, or your favorite cheese
- Place casserole dish on a baking sheet when baking. This helps prevent any messy overflow. It also helps prevent the bottom of the casserole from becoming too dark.
- Check casserole after 45 minutes of baking. If becoming too dark on the top, cover with a piece of foil. Return to oven for an additional 15 minutes.

I absolutely love breakfast sausage! I don't make it all that often, mainly because breakfasts around here are usually just yogurt + granola or cereal, but now I'm craving breakfast sausage. This casserole looks amazing, and it would be perfect for Thanksgiving or Christmas morning!
