How to Make Sausage Breakfast Casserole Recipe
Step 1: Brown the Sausage
Start by heating a large skillet over medium heat and cook the breakfast sausage until it’s nicely browned and crumbled into flavorful bits. Draining the excess fat here is important to keep the casserole from being greasy while maintaining that deep savory flavor you crave.
Step 2: Whisk the Egg Mixture
In a large bowl, combine the eggs, whole milk, salt, and black pepper. Whisk everything together until the mixture looks smooth and uniformly blended. This egg custard is what sets your casserole apart, creating a rich and tender texture that holds all the ingredients together beautifully.
Step 3: Prepare the Baking Dish
Generously grease a 9×13-inch baking dish so nothing sticks. Then spread the frozen shredded hash browns evenly on the bottom, creating the first layer that will absorb all those delicious juices during baking.
Step 4: Layer the Sausage and Cheese
Scatter the cooked sausage evenly over the hash browns, ensuring each bite gets some meaty goodness. Next, sprinkle the shredded cheddar cheese across the top for that classic gooey layer that’s simply irresistible once baked.
Step 5: Pour the Egg Mixture
Carefully pour the whisked egg mixture over all the layers in the dish. Make sure the eggs cover everything evenly, letting the custard seep down to fill all the delicious nooks and crannies.
Step 6: Bake to Perfection
Place the casserole in a preheated oven at 350°F (175°C) and bake for 45 to 50 minutes. You’ll know it’s done when the center sets firm and the top turns a beautiful golden color, signaling that perfect blend of creamy and crispy.
Step 7: Rest and Serve
After removing from the oven, let the casserole rest for about 10 minutes before slicing. This resting time allows everything to settle, making sure each slice holds together nicely and is ready to be enjoyed.

Garnishes
Brighten your plates by adding fresh garnishes like chopped green onions or parsley for a pop of color and a fresh, mild crunch that contrasts the rich casserole beautifully.
Side Dishes
This casserole is hearty on its own but pairs wonderfully with light side options like fresh fruit salad, mixed greens tossed in a tangy vinaigrette, or even warm toasted English muffins to round out the meal.
Creative Ways to Present
For extra flair, try serving individual portions in small ramekins or muffin tins for a grab-and-go breakfast at brunch parties. You can even drizzle hot sauce or a dollop of sour cream on top to give each serving a personalized kick.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover leftovers tightly with foil or plastic wrap and pop them in the fridge. They’ll stay fresh for up to 3 days — perfect for quick breakfasts that still feel like a treat.
Freezing
This Sausage Breakfast Casserole Recipe freezes beautifully. Wrap the whole baked dish tightly or freeze individual portions in airtight containers for up to 2 months. Just thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through, about 15-20 minutes. For even quicker reheating, microwave individual slices covered loosely with a damp paper towel to maintain moisture.
FAQs
Can I use a different type of sausage?
Absolutely! While breakfast sausage is traditional, you can substitute with turkey sausage, spicy chorizo, or even a plant-based sausage to suit your dietary needs and flavor preferences.
Do I have to use frozen hash browns?
Frozen shredded hash browns are convenient and give the casserole that classic texture, but you can also use fresh shredded potatoes if you prefer, just be sure to squeeze out excess moisture before layering.
Can I make this casserole dairy-free?
Yes! Substitute whole milk with your favorite dairy-free alternative like almond or oat milk, and use a dairy-free cheese to keep the flavor without compromising your dietary restrictions.
How long does the casserole keep in the fridge?
Stored properly in an airtight container, it will stay delicious for up to 3 days, making it a fantastic option for meal prepping ahead of busy mornings.
Can I add vegetables to the casserole?
Definitely! Adding sautéed bell peppers, onions, spinach, or mushrooms boosts both flavor and nutrition. Just cook the vegetables beforehand to prevent excess moisture from affecting the casserole’s texture.
