Ingredients You’ll Need
Gathering simple, fresh ingredients is the key to making this bake so delicious and vibrant. Each component plays a role in building layers of flavor, from the savory sausage to the fresh, green spinach which adds a nutritious pop of color and tender texture.
- 10 large eggs: The base of your bake, providing richness and a light, fluffy texture when whipped with milk.
- 1/2 cup milk: Creates a creamy custard consistency, making every bite smooth and tender.
- 1 pound Italian sausage: Adds robust, savory flavor and protein, perfectly browned for depth.
- 3 cups fresh spinach: Brings in earthiness and vibrancy, wilting down to add a tender bite and nutritional boost.
- 2 cups sliced mushrooms: Contribute an amazing umami element and satisfyingly meaty texture.
- 1 cup shredded mozzarella cheese: Melts beautifully, adding gooey, mild cheesiness that complements the other flavors.
- 1/2 teaspoon salt: Enhances all the natural flavors without overpowering.
- 1/4 teaspoon black pepper: Adds a gentle kick and warmth.
- 2 tablespoons olive oil: Used for sautéing the sausage and vegetables, adding richness and ensuring golden browning.
How to Make Hearty Sausage Spinach Mushroom Egg Bake Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 375 degrees Fahrenheit. Grease a 9-by-13-inch baking dish so your hearty egg bake won’t stick and will come out easily after baking.
Step 2: Brown the Sausage
Heat one tablespoon of olive oil over medium heat in a large skillet. Add the Italian sausage, breaking it apart with your spatula, and cook until it’s nicely browned and fully cooked, about 6 to 8 minutes. Once done, transfer the sausage to a plate to keep warm.
Step 3: Sauté Mushrooms and Spinach
In the same skillet, pour in the remaining tablespoon of olive oil. Toss in the sliced mushrooms and cook for about five minutes until they turn golden brown and fragrant. Next, stir in the fresh spinach and sauté just until it wilts. Then remove the skillet from the heat, letting those beautiful flavors meld together.
Step 4: Whisk the Eggs and Milk
In a large mixing bowl, crack in all ten eggs. Pour in the half cup of milk, then season with salt and black pepper. Whisk everything until the mixture is smooth and slightly frothy—this is what gives the bake that light, airy texture.
Step 5: Combine Ingredients
Add the cooked sausage, sautéed mushrooms and spinach, plus the shredded mozzarella cheese directly into the egg mixture. Stir everything gently and evenly to make sure each bite has a good balance of all those amazing flavors and textures.
Step 6: Pour and Smooth
Pour your combined mixture into the prepared baking dish. Use a spatula to smooth the top so it bakes evenly and looks inviting once it’s out of the oven.
Step 7: Bake
Pop the dish into your preheated oven and bake for 30 to 35 minutes. You want the center to be just set but still moist, with the edges turning a lovely golden brown. The aroma alone will have you counting down the minutes!
Step 8: Cool and Serve
Once baked, allow the egg bake to cool for about five minutes before slicing. This cool-down lets it firm up a bit, so your slices hold together beautifully when served.
How to Serve Hearty Sausage Spinach Mushroom Egg Bake Recipe
Garnishes
Sprinkle chopped fresh herbs like parsley or chives on top for an extra fresh burst and beautiful pop of color. A light dusting of parmesan cheese can also elevate the dish with a subtle nutty flavor and extra savory notes.
Side Dishes
Pair your egg bake with some crisp, fresh fruit like orange slices or berries to balance the richness. A simple green salad tossed with lemon vinaigrette or even some crusty toast rounds out the meal perfectly.
Creative Ways to Present
For a brunch gathering, serve the egg bake in individual ramekins or muffin tins for single portions. You can even jazz it up by topping each slice with a dollop of sour cream or avocado slices for added creaminess and flair.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftover Hearty Sausage Spinach Mushroom Egg Bake tightly with plastic wrap or store in an airtight container. It will keep well in the refrigerator for up to four days, making it a perfect meal prep option.
Freezing
If you want to store it longer, slice the egg bake into portions and wrap each piece in plastic wrap and aluminum foil or use freezer-safe containers. It can be frozen for up to two months, retaining most of its texture and flavor when thawed.
Reheating
Reheat leftover slices gently in the oven at 325 degrees Fahrenheit for about 10 to 15 minutes or microwave on medium power for a couple of minutes until warmed through. Add a sprinkle of cheese on top before reheating for a melty finish.
FAQs
Can I substitute turkey sausage for the Italian sausage?
Absolutely! Turkey sausage is a great leaner alternative that still brings plenty of flavor, just make sure it’s fully cooked before mixing it into the egg bake.
Is fresh spinach necessary or can I use frozen spinach?
Fresh spinach works best here for its texture and color, but if you only have frozen, thaw it completely and squeeze out excess moisture to avoid a watery bake.
Can I make this egg bake vegetarian?
Yes! Simply omit the sausage and consider adding extra mushrooms, bell peppers, or your favorite veggies to maintain hearty flavor and substance.
What type of cheese works best besides mozzarella?
Cheeses like cheddar, Monterey Jack, or even feta can be delicious substitutions, each adding their own unique twist to this classic egg bake.
How do I know when the egg bake is fully cooked?
The center should be just set and not jiggly. A knife inserted in the middle should come out clean or with only a few moist crumbs attached when the bake is done perfectly.
