How to Make Sausage Hash Brown Casserole

Frequently Asked Questions
Why should I pat the hash browns dry?
Thawing and patting dry the hash browns prevents excess moisture, ensuring your casserole is perfectly crispy instead of soggy.
Can I use a different type of sausage?
Absolutely! You can use breakfast sausage, hot sausage, sage sausage, or even Italian sausage for a unique twist.
Can I add vegetables?
Yes! Bell peppers, mushrooms, or spinach make a delicious addition. Sauté them with the sausage for extra flavor.
Can I freeze this casserole?
Definitely! Assemble the casserole, wrap it tightly, and freeze it before baking. When ready to cook, bake straight from the freezer with a slightly longer cooking time.
How do I store leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or on the stovetop for the best texture.

Notes
- Make sure the hash browns are thawed and dried. Pat them dry with a paper towel. You don’t want that extra moisture to make your casserole runny.
- Frozen hash browns come in different size bags. I used a 30 ounce bag but a 2 pound bag will also work.
- You do not have to brown the hash browns. I like this step as it gives the hash browns some color and additional texture but it’s not necessary for this dish to still be delicious.
- Like most casseroles, this is perfect to make the night before to have ready to bake the next morning!
- This casserole can be frozen.
- For an additional kick of flavor, try adding about a teaspoon of cajun or creole seasoning into the egg mixture along with the salt and pepper.
