Spinach and Mushroom Strata

This strata, like its ham counterpart, is great for an easy wake-up-and-serve breakfast. Prep everything the night before and set it for the morning leaving no one hungry and waiting. This vegetarian breakfast option starts with a broil of mushrooms and shallots. Then incorporating milk, eggs, and spices into a savory custard which is tossed with bread cubes. Finally mixing in the mushrooms, spinach, and gruyère for a delightfully hearty breakfast casserole. Finish with a broil to brown the melted cheese and you’ll have the whole house peeking into the kitchen wondering what’s for breakfast.
