How to Make Sausage Hash Brown Breakfast Casserole
-
Preheat your oven to 375°F (190°C). Greasing a 9×13-inch baking dish with cooking spray or butter will prevent any sticking, ensuring your casserole comes out in one beautiful piece.
-
Cook the breakfast sausage in a large skillet over medium heat for about 5-7 minutes, breaking it apart as it browns. Once fully cooked, drain any excess grease and set the sausage aside to keep it flavorful and moist.
-
Spread the thawed hash browns evenly across the bottom of your greased baking dish. For those who crave extra crispiness, lightly sauté the hash browns in the pan for a few minutes before layering for added texture.
-
Layer the cooked sausage evenly over the hash browns. In a separate mixing bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and onion powder. Pour this creamy egg mixture over the sausage and hash browns, and finish by topping it all off with a generous handful of shredded cheddar cheese.
-
Bake the casserole in your preheated oven for 35-40 minutes. Look for the eggs to be fully set and the cheese to develop a gorgeous golden brown melty crust on top.
-
Cool the casserole for about 5 minutes before slicing. This slight resting time ensures it holds together, making it easier to serve. Enjoy each warm slice filled with goodness!
Optional: Sprinkle fresh herbs on top for a pop of color and flavor before serving.

Chef's Helpful Tips
- To ensure your Sausage Hash Brown Breakfast Casserole turns out perfectly, always preheat your oven fully to 375°F before baking to promote even cooking.
- Avoid overcooking the sausage; browning it just until cooked through will keep it flavorful without becoming dry.
- When spreading the hash browns, make sure they are evenly layered to help the casserole hold its shape and achieve a nice crisp on the bottom.
- Lastly, aim for a baking time of 35-40 minutes, but check for doneness a few minutes early to prevent overcooking the eggs and drying out the dish.
Sausage Hash Brown Breakfast Casserole Recipe FAQs
How do I select the right breakfast sausage?
Absolutely! When choosing breakfast sausage, look for ones that have a good fat content for flavor, ideally around 20-30%. Checking for high-quality ingredients without fillers or preservatives is important, too. The flavor profile can vary widely, from mild to spicy, so choose based on your taste preferences. I often go for a blend that’s slightly spicy to give the casserole that extra kick!
How should I store leftovers?
Very! To keep your Sausage Hash Brown Breakfast Casserole fresh, store any leftovers in an airtight container in the fridge for up to 3 days. Reheating is a breeze—simply pop individual portions in the microwave or warm them up in the oven at 350°F (175°C) for about 15-20 minutes until warmed through.
Can I freeze the casserole?
Absolutely! To freeze, I recommend assembling the casserole but not baking it. Cover it tightly with aluminum foil or place it in a freezer-safe container. It can last up to 2 months in the freezer. When you’re ready to enjoy, thaw it overnight in the fridge, then bake at 350°F (175°C) for 20-30 minutes until the cheese is melted and the casserole is heated through.
What if my casserole is too watery?
Oh, that can happen! If your casserole ends up too watery, it could be due to excess moisture in the hash browns or undercooked sausage. To fix this, I suggest letting it cool a bit after baking, allowing excess moisture to evaporate. You can also try adding an extra egg or a bit more cheese to help bind it up when you prepare it next time.
Is this recipe allergy-friendly?
Very! This Sausage Hash Brown Breakfast Casserole can be made allergy-friendly by substituting ingredients. For a gluten-free option, ensure your hash browns and sausage are certified gluten-free. If you’re avoiding dairy, try using a non-dairy milk and cheese alternative. Always double-check labels for allergens if you’re cooking for someone with food sensitivities!
What is the best way to reheat frozen casserole?
For the best results, thaw your Sausage Hash Brown Breakfast Casserole in the fridge overnight before reheating. To reheat it, preheat your oven to 350°F (175°C). Bake for about 20-30 minutes or until heated throughout. If it’s still a bit cold in the middle, give it a few extra minutes, but check frequently to make sure it doesn’t overcook. Enjoy every delicious bite!
