Instructions

Preheat Oven and Prepare 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 and cook until browned and fully cooked through, about 6 to 8 minutes. Once done, transfer the 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 just wilted. Remove the skillet from heat.
Mix Eggs and Seasoning: In a large bowl, whisk together the eggs, milk, salt, and black pepper until the mixture is smooth and evenly combined.
Combine Ingredients: Add the cooked sausage, sautéed vegetables, and shredded mozzarella cheese into the egg mixture. Stir everything well to combine all the ingredients thoroughly.
Assemble in Baking Dish: Pour the combined mixture evenly into the prepared baking dish, smoothing the top with a spatula for an even bake.
Bake: Place the baking dish in the preheated oven and bake for 30 to 35 minutes, or until the center is just set and the edges turn golden brown.
Cool and Serve: Remove from the oven and let the egg bake cool for 5 minutes before slicing and serving warm.

Notes

Use a 9×13-inch baking dish to ensure even baking.
Italian sausage can be spicy or mild depending on preference; adjust accordingly.
Fresh spinach is preferred for best texture but you can substitute with frozen spinach if drained well.
Allow the bake to cool slightly; this helps it set and makes slicing easier.
Leftovers can be refrigerated for up to 3 days and reheated before serving.
