This overnight pumpkin spice French toast bake is a cozy, custardy breakfast casserole that requires just 15 minutes of prep the night before. The bread soaks up a spiced pumpkin custard overnight, then bakes to golden perfection in the morning, making it perfect for busy mornings, holiday brunches, or impressing guests with minimal effort.
Use stale bread for best texture; if using fresh, cube and toast at 300°F for 10 minutes. Don’t skip the overnight soak—it ensures even flavor and prevents dry spots. Start checking for doneness at 35 minutes. For a homemade pumpkin pie spice blend, mix 3 tablespoons cinnamon, 2 teaspoons ground ginger, 2 teaspoons ground nutmeg, 1½ teaspoons ground allspice, and 1½ teaspoons ground cloves. Room temperature ingredients blend more smoothly.
