This recipe comes together with a handful of ingredients that deliver big flavor. Here’s what you’ll need:

- Diced Onion (½ large): Enhances the dish’s flavor and adds texture.
- Shredded Cheese (2 ½ cups): Sharp cheddar works beautifully, but you can mix it up with Colby Jack, Pepper Jack, or a Mexican blend.

- Seasonings: Onion powder, garlic powder, sea salt, and black pepper create a flavorful base.
Step-by-Step Guide to make Sausage Hashbrown Breakfast Casserole
Prep: Preheat oven to 350°F (175°C) and grease a 9x13-inch baking dish. Take the hash browns out of the freezer to begin thawing.
Cook the Sausage: In a skillet over medium-high heat, cook the breakfast sausage, breaking it into crumbles, until browned and cooked through. Add the diced onion and cook until softened, about 3–4 minutes. Drain any excess grease and set aside.
Prepare the Egg/Hash Brown Mixture: In a large mixing bowl, whisk together the eggs, milk or cream, onion powder, garlic powder, salt, and pepper until well combined. Add two cups of shredded cheddar and hash browns and mix until combined.
Assemble Casserole: Add sausage mixture to the bottom of the casserole dish. Pour the egg and hash brown mixture into the casserole dish. Sprinkle the remaining ½ cup of cheddar cheese on top.
Bake: Place in the oven and bake for 40–45 minutes, or until the eggs are set and the top is golden. A knife inserted in the center should come out clean.
Serve: Let the casserole cool for a few minutes before slicing. Serve warm and enjoy!
Top Tips
Spice It Up: Use spicy sausage or add a dash of cayenne pepper or red pepper flakes to the egg mixture.
Make It Ahead: This casserole is a dream for busy mornings. Assemble it the night before, cover it tightly, and refrigerate. When ready to bake, simply pop it in the oven. Note: You may need to add a few extra minutes to the baking time if it’s straight from the fridge.
Cheese Variety: Feel free to experiment with different cheeses. Colby Jack and Pepper Jack add a delicious twist, while mozzarella or Monterey Jack create a milder flavor.
Add Veggies: Boost the nutrition by mixing in diced bell peppers, spinach, or mushrooms. Cook them slightly before adding to prevent excess moisture.
Frequently Asked Questions
1. Can I use fresh potatoes instead of frozen hash browns?
Absolutely! Grate fresh potatoes, then squeeze out as much moisture as possible before mixing them into the egg base. This ensures the casserole doesn’t turn out watery.
2. Can I freeze this breakfast casserole?
Yes! Bake the casserole first, let it cool completely, and then wrap it tightly in plastic wrap followed by aluminum foil. Store it in the freezer for up to 3 months. To reheat, thaw overnight in the fridge and warm in the oven at 350°F until heated through.
3. How long does this casserole last in the fridge?
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or oven. This Pyrex casserole dish has a lid, and I LOVE it for recipes like this.

Terry says
The directions say to put the sausage on the bottom of the casserole dish but it looks like they added the sausage to the eggs and hash browns?
