- Breakfast sausage: This adds a savory flavor and hearty texture. You can use pork, turkey, or even a plant-based option for a lighter twist.
- Frozen hashbrowns: These are the base of the casserole, providing that comforting potato goodness. They save time and effort, but fresh potatoes can work too if you’re feeling adventurous!
- Shredded cheddar cheese: This melty goodness brings richness and a delightful sharpness. Feel free to swap it for your favorite cheese, like Monterey Jack or pepper jack for a kick.

How to Make Overnight Sausage Hashbrown Casserole

Step 1: Cook the Sausage
Start by heating a skillet over medium heat. Add the breakfast sausage and cook until it’s browned and crumbly. This usually takes about 5-7 minutes. Make sure to drain any excess fat. This step is crucial for keeping the casserole from becoming greasy!

Step 2: Combine Ingredients
In a large mixing bowl, combine the cooked sausage, frozen hashbrowns, and shredded cheddar cheese. Stir gently to mix everything evenly. The cheese will melt beautifully during baking, creating a gooey, cheesy delight!

Step 3: Prepare the Egg Mixture
In another bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and onion powder. This mixture is what binds everything together. Make sure it’s well combined; you want every bite to be flavorful!

Step 4: Mix and Transfer
Pour the egg mixture over the hashbrown and sausage mixture. Stir until everything is well coated. Then, transfer this delicious mixture into a greased 9×13 inch baking dish. Spread it out evenly, so it cooks uniformly.

Cover the baking dish with plastic wrap or aluminum foil and pop it in the refrigerator overnight. This step allows the flavors to meld beautifully. Plus, it makes your morning routine a breeze!

The next morning, preheat your oven to 350°F (175°C). Remove the casserole from the fridge and uncover it. Bake for 45-50 minutes, or until the top is golden brown and the casserole is set. Your kitchen will smell heavenly!

Step 7: Serve and Enjoy
