Why This Recipe Works
I am always on the lookout for the best egg casserole recipes. Breakfast casserole recipes are my favorite brunch dishes, and I’ve been known to make them for dinner when I get tired of the same old chicken recipes we normally have.
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.
- 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
- Store leftovers in an airtight container in the fridge (or even in the freezer).
- For reheating, I like popping slices in the microwave.
- Garnish with green onions or parsley or some sour cream.
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.

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.

Can this also be made using fresh shredded potatoes? Example ‘Just Potatoes’ shredded potatoes or hand shredded?
I havne’t tried that but yes I think so – since the potatoes are thawed before they go in.
If I increase the quantity to 16 servings, will it still fit in a 9 x 13 casserole? Thanks!
It’s pretty full – you may want to make two 9×9 pans instead.
My family is going wheat free for the month of February, to see if it helps some health issuesโฆfeeding them has been tricky. I made this for dinner and my husband and sons LOVED it! I will be adding this to my wheat free arsenal!
