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 you double this recipe to use a full package of hash browns?
Searched all over the web for a better ‘Hash brown breakfast casserole’ and finally settled on this one. I’m so glad I did. It has some spice in it, and the egg to milk ratio is great. I’ve tried other recipes and they had so much milk the end product was wet. I really like the idea of layering the hash browns, sausage and cheese (I actually mixed them all together to ensure the cheese didn’t just stay on top). I cooked up a little onion and bell pepper in the sausage fat and threw that in as well. I stored the hash brown mixture separate from the egg mixture overnight, then just poured the egg mixture over the hash browns in the morning and threw it in the oven. It turned out great!
It was great!!!! I’ve made it several times for church and it goes quick!!!
6 STARS!! So delicious. I made this tonight and it was a HOMERUN! I made the recipe exactly as written with the exception of one extra step that I have learned when using grocery bought hashbrown potatoes. Y’all can take it or leave it depending on your specific tastes. Before you spread the potatoes in the baking dish lay them out on a paper towel with another paper towel on top and dry them by pressing gently with your fingers. Get as much moisture out of the potatoes as you can and then spread on the prepared dish. It makes for a delicious crispy, potato and cheesy crust that can’t be beat. Thank you so much for this recipe!
Can leftovers be reheated?
I make casseroles (including breakfast ones like this) all the time. I portion & freeze them, then pull them the day before. The breakfast casseroles hold up extremely well. So even if you are just eating it the next day it will be good.
Can this recipe be frozen? If so would you bake it first
