Ingredients
Scale
Egg Mixture
- 10 large eggs
- 1/2 cup milk
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Sausage and Vegetables
- 1 pound Italian sausage
- 3 cups fresh spinach
- 2 cups sliced mushrooms
- 2 tablespoons olive oil
Cheese
- 1 cup shredded mozzarella cheese
Instructions
- Preheat and Prepare Baking Dish: Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish to prevent sticking.
- Cook Sausage: Heat 1 tablespoon of olive oil in a skillet over medium heat. Add the Italian sausage, breaking it apart as it cooks, and cook for 6–8 minutes until browned and fully cooked through. Transfer the cooked sausage to a plate and set aside.
- Sauté Vegetables: In the same skillet, add the remaining tablespoon of olive oil. Add the sliced mushrooms and cook for about 5 minutes until they are browned and tender. Then stir in the fresh spinach and sauté until wilted, about 1-2 minutes. Remove the skillet from heat.
- Mix Eggs: In a large bowl, whisk together the eggs, milk, salt, and black pepper until smooth and well combined.
- Combine Ingredients: Add the cooked sausage, sautéed vegetables, and shredded mozzarella cheese to the egg mixture. Stir thoroughly to combine all ingredients evenly.
- Pour and Smooth: Pour the combined mixture into the prepared baking dish, smoothing the top evenly with a spatula.
- Bake: Place the baking dish in the oven and bake for 30–35 minutes, or until the center is just set and the edges are golden brown.
- Cool and Serve: Remove the bake from the oven and let it cool for 5 minutes before slicing into portions and serving.
Notes
- Use fresh spinach for best texture and flavor; frozen can be used but make sure it is well drained.
- This dish can be made ahead and reheated in the oven or microwave.
- For a lower-fat option, use turkey sausage and reduced-fat mozzarella cheese.
- Feel free to add other vegetables such as bell peppers or onions for added flavor.
- Ensure the egg bake is fully cooked by checking that the center is set and there is no runny egg.
