How to Make Make-Ahead Sausage Hashbrown Casserole
Step 1: Cook the Sausage
In a skillet over medium heat, cook the sausage until browned and fully cooked. Break it into crumbles as it cooks. Add the chopped onion and sauté for 2–3 minutes until softened. Drain excess grease and set aside.
Step 2: Prepare the Egg Mixture
In a large bowl, whisk together the eggs, milk, sour cream, salt, pepper, and garlic powder until smooth and well combined.
Step 3: Assemble the Casserole
Grease a 9×13-inch baking dish. Spread the thawed hashbrowns evenly across the bottom. Sprinkle the cooked sausage mixture over the top, followed by the shredded cheese.
Step 4: Add the Eggs
Pour the egg mixture evenly over the casserole, gently pressing down so everything is fully coated.
Step 5: Cover and Chill
Cover the dish tightly with foil or plastic wrap and refrigerate for at least 6 hours or overnight. This step is key to the “make-ahead” magic.
Baking and Serving
When you’re ready to cook:
Preheat the oven to 350°F (175°C).
Remove the casserole from the refrigerator and let it sit at room temperature for 15 minutes.
Bake uncovered for 45–55 minutes, or until the center is set and the top is lightly golden.
Let rest for 10 minutes before slicing and serving.
Tips for the Best Results
Thaw hashbrowns completely to avoid excess moisture.
Use freshly shredded cheese for better melting.
Let it rest after baking for cleaner slices.
For a crispier top, broil for the last 2–3 minutes.
Easy Variations to Try
Spicy Version: Use hot sausage and add diced jalapeños.
Veggie-Loaded: Add mushrooms, spinach, or bell peppers.
Southwest Style: Mix in pepper jack cheese and cumin.
Low-Carb Option: Replace hashbrowns with cauliflower hash.
Storage and Reheating
Leftovers keep well in the refrigerator for up to 4 days. Individual portions can be reheated in the microwave or oven, making this casserole perfect for grab-and-go breakfasts.
