Ingredients
10 large eggs
1 cup milk
1 pound sausage, cooked and crumbled
2 cups fresh spinach
1 cup mushrooms, sliced
1 cup bell peppers, diced
1 small onion, diced
1 ½ cups shredded cheddar cheese
1 tablespoon olive oil or butter
1 teaspoon salt
½ teaspoon black pepper
Instructions
1. Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish and set aside.
2. In a skillet over medium heat, cook the sausage until browned and fully cooked. Drain and set aside.
3. In the same skillet, add olive oil or butter and sauté onion, bell pepper, mushrooms, and spinach until tender and wilted.
4. In a large bowl, whisk together eggs, milk, salt, and pepper. Stir in half of the cheddar cheese.
5. Fold in the cooked sausage and sautéed vegetables into the egg mixture.
6. Pour the mixture into the prepared baking dish and top with the remaining cheese.
7. Bake for 35–40 minutes, or until the center is set and the top is golden.
8. Let rest 5–10 minutes before slicing. Serve warm.
Notes
Be sure to sauté the vegetables until their moisture is cooked off to avoid a watery bake.
This recipe is ideal for meal prep—portion and refrigerate or freeze for future meals.
You can swap in different cheeses or veggies depending on your preferences.
