Perhaps best of all, this Sausage Egg Casserole is a complete meal in one dish, eliminating the need to prepare multiple breakfast items.

Ingredients

For this delicious breakfast egg bake, you’ll need:

• 1 pound (454g) breakfast sausage, casings removed
• 6 large eggs
• 2 cups (473ml) whole milk
• 2 cups (226g) shredded cheddar cheese, divided
• 6 slices white bread, cubed (about 6 cups)
• 1 teaspoon salt
• ½ teaspoon dry mustard
• ¼ teaspoon black pepper
• ¼ teaspoon onion powder

The quality of sausage makes a significant difference in this Sausage Egg Casserole – use a premium breakfast sausage with a flavor profile you enjoy (mild, spicy, or maple-flavored all work wonderfully). For the cheese, a sharp cheddar provides the best flavor contrast, but you can substitute part of it with Gruyère or Monterey Jack for variety. Fresh eggs are essential since they’re the foundation of this breakfast casserole recipe.

Pro Tips

Use Day-Old Bread: One of the secrets to a perfect Sausage Egg Casserole is using slightly stale bread. Fresh bread tends to become too soggy, while day-old bread absorbs the egg mixture perfectly while maintaining some texture. If you only have fresh bread, cube it and leave it out for a few hours before assembling your casserole.

Brown The Sausage Thoroughly: Take the time to properly brown your sausage, breaking it into small, even pieces as it cooks. This develops a deeper flavor and ensures the sausage is fully cooked before it goes into the casserole. Drain excess fat to prevent a greasy final dish, but leave a little for flavor.

Overnight Rest Is Essential: While you can bake this casserole immediately after assembly, allowing it to rest in the refrigerator for at least 4 hours (or overnight) yields dramatically better results. This resting period allows the bread to fully absorb the egg mixture, resulting in a more uniform texture and better flavor distribution throughout your Sausage Egg Casserole. The difference is remarkable and worth planning ahead for.

Instructions

Step 1: Prepare The Sausage

Heat a large skillet over medium-high heat. Add the breakfast sausage, breaking it apart with a wooden spoon as it cooks. Brown the sausage thoroughly until no pink remains, about 7-8 minutes. As you cook, continue breaking the sausage into small, evenly-sized pieces to ensure it distributes well throughout the casserole. Once fully cooked, transfer the sausage to a paper towel-lined plate to drain excess grease.

Step 2: Prepare The Baking Dish

Grease a 9×13 inch baking dish with butter or cooking spray. This prevents sticking and helps create those desirable crispy edges that add texture to your Sausage Egg Casserole. Spread the cubed bread evenly across the bottom of the prepared dish.

Step 3: Layer The Ingredients

Sprinkle the cooked sausage evenly over the bread cubes. The meat should be distributed uniformly to ensure every serving has plenty of sausage flavor. Next, sprinkle 1½ cups of the shredded cheese over the sausage layer, reserving the remaining ½ cup for the top.

Step 4: Create The Egg Mixture

In a large bowl, whisk together the eggs, milk, salt, dry mustard, black pepper, and onion powder until well combined. Beat the mixture thoroughly to incorporate air, which helps create a fluffier texture in your finished Sausage Egg Casserole. The dry mustard adds a subtle depth of flavor that complements the sausage beautifully.

Step 5: Assemble And Rest

Pour the egg mixture evenly over the layered ingredients in the baking dish. Press down gently with a spatula to ensure all bread pieces are submerged in the egg mixture. Sprinkle the remaining ½ cup of cheese on top. Cover the dish with plastic wrap and refrigerate for at least 4 hours or overnight. This resting period is crucial for the best texture and flavor development.

Step 6: Bake To Perfection

When ready to bake, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature while the oven preheats. Bake uncovered for 45-50 minutes, or until the center is set and the top is golden brown. A knife inserted in the center should come out clean. Let the Sausage Egg Casserole rest for 10 minutes before serving to allow it to set up properly for easier cutting and serving.

Variations

Mediterranean Sausage Egg Casserole: Transform this classic breakfast into a Mediterranean delight by using Italian sausage instead of breakfast sausage. Add ½ cup chopped roasted red peppers, ¼ cup sliced Kalamata olives, 1 cup fresh spinach, and substitute feta cheese for half of the cheddar. The combination creates a flavor-packed breakfast egg bake with a delightful Mediterranean twist.

Vegetarian Option: Create a meatless version by replacing the sausage with 2 cups of sautéed vegetables like bell peppers, onions, and mushrooms. Add 1 teaspoon of Italian seasoning and a pinch of red pepper flakes to maintain the robust flavor profile of the original Sausage Egg Casserole. This variation is equally satisfying and perfect for vegetarian guests.

Low-Carb Adaptation: For those following a low-carb diet, substitute the bread with 2 cups of cauliflower rice that has been sautéed until tender and thoroughly dried. This creates a similar texture while significantly reducing the carbohydrate content. The Sausage Egg Casserole maintains its hearty appeal while becoming keto-friendly.

Storage and Serving

The Sausage Egg Casserole can be stored in an airtight container in the refrigerator for up to 4 days. For longer storage, cut the cooled casserole into individual portions and freeze them wrapped in plastic wrap and aluminum foil for up to 2 months. Reheat refrigerated portions in the microwave for 1-2 minutes or in a 350°F oven for about 10 minutes until heated through.

Serve this hearty breakfast dish with a side of fresh fruit for a refreshing contrast to the savory flavors. For a more substantial brunch, pair it with a light arugula salad dressed with lemon vinaigrette, which cuts through the richness of the Sausage Egg Casserole. Another excellent serving suggestion is to offer warm maple syrup on the side – the sweet and savory combination is unexpectedly delicious and a favorite among those who enjoy flavor contrasts.

For a special touch when entertaining, garnish each serving with fresh herbs like chives or parsley and provide hot sauce on the side for those who enjoy a spicy kick.
