Do you ever need a filling breakfast to feed your family? Or maybe a make ahead breakfast to serve a crowd? This breakfast hash brown casserole is just what you need! I’ve made this for a weekend breakfast for my family. It was perfect for my family.  

This breakfast casserole can be easily reheated or even eaten at room temperature. My husband even loved the leftovers cold the next day.

How do I make hash brown casserole?

Spray a 9 x 13 inch baking dish with nonstick cooking spray. Place potatoes in the bottom of the dish. Hash browns in a glass baking dish.

Add cooked sausage and chopped bell peppers.

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. 

Testing to see if an egg bake is baked all the way through.

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 oz 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!
