What is hashbrown casserole?
Hashbrown casserole is a breakfast staple. It's essentially several breakfast ingredients mixed together and baked in the oven to perfection.
Hashbrown casserole includes hashbrowns (obvious from the title of this recipe), sausage, egg, and cheese. The ratios of the those ingredients, extras, and method of cooking will change based on each recipe.
I'm bias, by this cheesy hashbrown casserole recipe is my favorite!
What ingredients do I need?
The ingredients for this recipe are simple!
- Shredded hash browns - This is the star of the recipe! You can shred your own potatoes to make hashbrowns OR you can buy a bag of frozen shredded hashbrowns. I have made this with frozen hashbrowns (like these Simply Potato Hashbrowns) every time to keep it quick and easy, and it works PERFECTLY.
- Egg whites - The egg whites will serve as the liquid for this recipe along with a source of protein!
- Turkey Sausage Crumbles - It's important to use pre-cooked turkey sausage for this recipe! I buy a bag of sausage crumbles (like these Jimmy Dean crumbles) and mix them in (again, keeping it quick and easy), but you could also cook the sausage yourself. You just need to make sure the meat is cooked before adding it to the casserole and putting it into the oven.
- Cheddar cheese - Shredded cheddar cheese will make this hashbrown casserole cheesy! I like the flavor that cheddar cheese provides with these ingredients, but any cheese will work great.
- Salt & pepper - A little bit of salt and pepper will provide extra flavor for this recipe, but are not required. If you want, add any of your favorite spices!
- Hot sauce - This is optional, but adding hot sauce onto the casserole after cooking will take it to the next level.
What substitutions can i make?
- This recipe is gluten-free.
- To make this recipe without dairy, use a dairy-free cheese.
- You can use any kind of sausage as well.
