Instructions:

Heat oven to 325º. Arrange bread in a single layer on a baking sheet and bake for 15 minutes, turning over once. Remove from oven and set aside.

In large skillet set over medium-high heat, sauté sausage, breaking up large pieces, until it begins to brown, about 5 minutes. Add onion and cook until onion is translucent. With a slotted spoon transfer meat mixture to a medium bowl and stir in spinach. Season with 1/2 teaspoon salt and pepper. Set aside to cool.

To assemble: Butter a 9 x 13 inch baking pan. Arrange half of the bread in a single layer, cutting pieces to fit if necessary. Spread half of the sausage mixture evenly on top and sprinkle evenly with half of the cheese. Repeat with a second layer of bread, remaining sausage mixture and top with cheese.

In a medium bowl, whisk together eggs, milk and remaining 1/2 teaspoon salt. Pour evenly over bread layers and cover with plastic wrap. Refrigerate for 8 hours or overnight.

To bake: Remove strata from refrigerator and let stand at room temperature for 30 minutes. Place rack in middle of oven and preheat to 350º. Bake for about 65-75 minutes, until top is puffed and lightly browned. Cool 5 minutes and serve.
