The Secret to the Best French Toast Casserole
The key to a perfect French toast casserole is slightly stale bread. Day-old bread absorbs the custard without turning mushy, giving the casserole structure and texture after baking.
Best Bread Options
- French bread (classic and sturdy)
- Brioche (rich and lightly sweet)
- Challah (soft, eggy, and luxurious)
Cut the bread into generous cubes rather than small pieces so it holds its shape while soaking.
Ingredients
- 1 loaf day-old French bread, brioche, or challah, cubed
- 8 large eggs
- 2 cups milk (whole milk recommended)
- ½ cup heavy cream (optional for extra richness)
