That’s where this casserole-style French toast comes in. It can be quickly assembled in the morning, or even the night before, before being baked off and served by the slice. This version has a punch of lemon zest in the rich custard and lots of bright blueberries throughout. Use fresh blueberries in the summer when they’re in season. But other times of year, frozen berries are a fine swap. (Don’t thaw frozen berries; adding them while still frozen helps prevent them from coloring the casserole too much.)

Baking, Freezing, and Reheating French Toast Casserole
The fully cooked casserole can be frozen, although it’s better when freshly baked. However, if you have leftovers to freeze, wrap individual portions in plastic wrap and then a layer of foil. Defrost the individual slices in the refrigerator overnight or in the microwave using the defrost setting. Heat till just warmed through in the microwave. If using frozen blueberries, add them to the casserole while still frozen (do not thaw). This helps prevent the berries from coloring the casserole too much. Leftovers will keep, refrigerated, for about 1 week and can be reheated in the microwave.
