Ingredients You’ll Need
Don’t let the simple ingredient list fool you: each component plays a key role in delivering that perfect blend of taste, texture, and color. These essentials come together beautifully, creating a dish that’s both wholesome and bursting with flavor.
- 10 large eggs: The foundation of this bake, providing a light and fluffy texture that holds the dish together.
- 1/2 cup milk: Adds creaminess and moisture for a tender egg base.
- 1 pound Italian sausage: Brings robust, savory flavor and juicy richness.
- 3 cups fresh spinach: Offers a pop of green freshness and subtle earthiness.
- 2 cups sliced mushrooms: Adds a meaty, umami layer that complements the sausage perfectly.
- 1 cup shredded mozzarella cheese: Melts into gooey pockets of cheesy goodness.
- 1/2 teaspoon salt: Balances and enhances all the flavors.
- 1/4 teaspoon black pepper: Adds a mild heat and depth.
- 2 tablespoons olive oil: For sautéing the sausage and vegetables, enriching flavor and texture.
How to Make Hearty Sausage Spinach Mushroom Egg Bake Recipe
Step 1: Preheat and Prepare Your Dish
Start by heating your oven to 375°F and greasing a 9×13-inch baking dish. This step ensures your egg bake doesn’t stick, making cleanup a breeze and helping the final product come out perfectly shaped and ready to slice.
Step 2: Cook the Italian Sausage
Heat 1 tablespoon of olive oil in a skillet over medium heat. Add the Italian sausage and cook it until it’s beautifully browned and fully cooked through, about 6 to 8 minutes. Cooking the sausage first builds a rich base flavor layer, and transferring it to a plate keeps it ready while you prepare the vegetables.
Step 3: Sauté the Mushrooms and Spinach
Using the same skillet, add the remaining tablespoon of olive oil. Toss in the sliced mushrooms and cook for 5 minutes until they are golden and carry that deep, meaty flavor. Then stir in the fresh spinach, sautéing just until it wilts. This combination adds earthiness and a lovely pop of color to your bake.
Step 4: Whisk the Egg Mixture
In a large bowl, whisk together the eggs, milk, salt, and black pepper until everything is smoothly combined. This mixture is the creamy canvas that holds all your flavorful ingredients together, giving the bake its light yet substantial structure.
Step 5: Combine Everything
Now, fold the cooked sausage, sautéed mushrooms, spinach, and shredded mozzarella into the egg mixture. Stir everything gently but thoroughly to make sure each bite delivers a perfect medley of flavors and textures.
Step 6: Bake the Egg Mixture
Pour the combined mixture into your prepared baking dish and smooth the top evenly. Pop it into your preheated oven and bake for 30 to 35 minutes. You’ll know it’s done when the edges turn golden and the center of the bake is just set to the touch—a sign of perfect, light fluffiness inside.
Step 7: Cool and Slice
After baking, let your egg bake rest for about 5 minutes. This little pause lets everything set up nicely, making it easier to slice and serve without it falling apart. Plus, it’s the perfect moment to take in that wonderful aroma!

Side Dishes
This egg bake pairs beautifully with crisp breakfast potatoes, a fresh mixed green salad, or some crusty bread to soak up any lingering flavors. For a lighter touch, sliced avocado or a simple fruit salad adds refreshing contrast, balancing out the rich, savory nature of the bake.
Creative Ways to Present
To impress guests or make everyday meals feel special, serve slices of the egg bake in individual ramekins or cut it into smaller bite-sized squares for a brunch buffet. You can also top each portion with a dollop of sour cream or a spoonful of salsa to add color and an exciting flavor kick.
Make Ahead and Storage

Freezing
This egg bake freezes beautifully. After baking and cooling completely, slice it and wrap individual portions tightly in plastic wrap or foil, then place them in a freezer-safe container or bag. Frozen, it can last up to 2 months, ready to be reheated whenever you need a hearty, home-cooked meal in minutes.
Reheating
Reheat leftovers in the microwave for one to two minutes or until warmed through. For a crispier texture, you can pop slices into a 350°F oven for about 10 minutes. Either way, you’ll enjoy a warm, comforting meal that tastes just as good as fresh out of the oven.
FAQs

Simply skip the sausage and add extra mushrooms or your favorite vegetarian protein like crumbled tofu or tempeh. Using a flavorful vegetarian sausage alternative also works great.
What’s the best way to reheat leftovers without drying them out?
