A warm, golden baked French toast casserole made with simple pantry ingredients. Perfect for Christmas morning, it can be assembled the night before or baked right away, allowing you to enjoy the festivities while the oven does the work.
For overnight preparation, assemble the casserole completely (including streusel), cover tightly with plastic wrap, and refrigerate for up to 12 hours. In the morning, let it sit at room temperature for 20 to 30 minutes while the oven preheats, then bake as directed, adding 5 to 10 minutes to the baking time if needed. Leftovers keep in the refrigerator for up to 3 days and can be frozen for up to 3 months.
