Hashbrown Breakfast Casserole is a cheesy NO FAIL egg casserole with hash browns, sausage and cheese. It’s the perfect brunch recipe and everyone loves it!
Why This Recipe Works
My cheesy egg casserole is something I make every year for Christmas morning and adding hash browns just seemed like a natural progression. One of my readers told me about her NO FAIL egg casserole with hash browns, sausage, and cheese so I decided I NEEDED to recreate it.
This recipe works because it’s a variation of one I’ve made so many times – and it’s basically dump and bake. It’s an easy recipe anyone can make!
Ingredients Needed
- Hashbrowns: I used about half of a 30 ounce package of frozen hash browns.
- Sausage – you can use bulk sausage or remove the casings from breakfast links. Either pork sausage or turkey sausage will work. You’ll need to brown it and drain the fat.
- Eggs – 6 large eggs went into this casserole.
- Cheese – I used 1 1/2 cups cheddar cheese that I shredded myself – shredding it yourself makes the cheese melt better. Use medium or sharp cheddar cheese.
- Spices – A teaspoon onion powder along with garlic, salt, pepper and dried mustard add tons of flavor.
How to Make Hashbrown Breakfast Casserole
- Whisk eggs with milk in a large bowl.
- Add your spices. I used garlic, onion, salt, pepper, and a bit of ground mustard. Whisk all of that together.
- Place a thick layer of hash browns on the bottom of a 9 x 13-inch baking dish.
- I added sausage to my egg casserole. Brown up some bulk breakfast sausage (if you only have links, remove the casings). Once the sausage is browned and drained, sprinkle on top of the potatoes.
- Then top it with shredded cheddar cheese (or you could also use Monterey Jack or Mozzarella).
- Pour the egg mixture over the top in the casserole dish. Cover, bake for about an hour, and then remove the foil cover about halfway through baking, about 20 minutes.
Variations
- Try swapping the sausage for bacon or make it a meat lovers casserole and add both. Or use ham!
- Make this country breakfast casserole with green chiles!
- Add cooked onions and bell peppers.
- Switch up the cheese – use mozzarella or Monterey Jack, Colby jack, or gouda.
Expert Tips
- Be sure to thaw your hash browns before making the casserole.
- Be sure to brown your sausage and drain the fat before assembling.
Storing and Making Ahead
- Store leftovers in an airtight container in the fridge (or even in the freezer).
- You can make this the night before and store it in the refrigerator. Allow to come to room temperature while the oven preheats then bake as directed.
- You can freeze hash brown breakfast casserole whole in the pan or slice it and freeze as individual servings.
FAQs
Yes you should thaw your hash browns so the egg bake isn’t soggy! Just leave them on the counter for about an hour, or in the refrigerator overnight.
The center will look set and no longer roll when you jiggle the pan.
Did you thaw your hash browns? Thaw and drain them before adding to the casserole – extra moisture will make a soggy casserole.

Can I make this in advance and eat the next day after reheating in oven?
I didn’t have time to make a run to the store for frozen hash browns, but I did have an abundance of potatoes in my bin, so I peeled 10 medium size and shredded them. Added a little time to the Prep but they are perfect. Casserole is in the oven now so I will let you know how the family likes it! ?⛄️
I love this egg casserole. Unfortunately my husband doesn’t. But you can also use ham. If you’ve baked a ham for the holidays this is a perfect way to use some of the leftovers. I like to fry mine a bit, set it aside and add as you would any other meat of your choice. This is the way I first saw this casserole. Very good!
Wow, looks wonderful. I can’t wait to try it.
Such a classic dish! This is really super easy to make. Thanks for sharing the recipe.
