Directions

1. In a 9-by-13-inch baking dish, whisk together eggs, milk, 1/4 cup sugar, vanilla, and salt.
2. Arrange bread in dish in a single layer; let soak 15 minutes. Turn bread over; cover, and refrigerate until most of the liquid is absorbed, at least 30 minutes and up to overnight.
3. Preheat oven to 350 degrees. Brush a rimmed baking sheet with butter. With a spatula, carefully transfer soaked bread to sheet. Bake until French toast is set in center and lightly browned on the bottom, 25 to 30 minutes.
4. Meanwhile, in a medium bowl, combine raspberries and remaining 1/4 cup sugar, mashing lightly with a fork.
5. Remove French toast from baking sheet with a thin metal spatula; serve with raspberry sauce and, if desired, sausage.
