This is the perfect dish for weekend brunch. It is especially convenient because you assemble it the night before and then bake it just before serving. For even more flavor, use Italian sausage instead of plain sausage. I make mine in a 4x8-inch Emile Henry ceramic loaf dish and serve it directly from the pan—along with a fruit salad—but it works equally well in a glass loaf pan.
MAKES 2 SERVINGS
1. Generously grease a 4x8-inch glass or ceramic loaf pan.
2. Place the bread in a medium bowl. Add the mushrooms, sausage, half of the mozzarella, the spinach, and onion and stir together with a spatula. Spread evenly in the baking dish.
3. In a medium bowl, whisk together the eggs, milk, garlic, Italian seasoning, salt, and pepper until thoroughly blended. Pour the mixture evenly over the bread. With a spatula, press on the bread cubes to flatten them a bit and make sure they are fully immersed in the liquid. Tightly cover and refrigerate for at least 1 hour or up to overnight to let the bread soak up the liquids.
4. Place a rack in the middle of the oven. Preheat the oven to 350°F. Uncover the casserole and bake for 30 minutes. Sprinkle with the Parmesan and remaining mozzarella and continue baking until the cheese is melted and browned, about 5 more minutes. Let cool on a wire rack for 10 minutes. Cut and serve, garnished with the parsley.
