Understanding the Ingredients
French Bread: The sturdy texture holds up beautifully when soaked in custard. Slightly stale breads work best to absorb flavors without falling apart.
Butter/Brown Sugar Base: This melts into a luscious caramel sauce as it bakes, adding sweetness and a golden crust underneath the bread cubes.
Milk & Eggs: The custard foundation that transforms the bread into soft, creamy layers inside the casserole, balancing richness and moisture perfectly.
The Best (and Worst) Breads for French Toast Casserole
Sturdy breads like French bread, brioche, or challah are ideal. They soak up the custard well and maintain texture through baking, which means you get a custardy yet structured casserole.
Flimsy sandwich bread or fresh soft bread can become too soggy and mushy. Avoid bread that’s very fresh or soft, as it lacks the density to hold the custard without collapsing.
| Bread Type | Texture | Suitable for Casserole? | Notes |
|---|---|---|---|
| French Bread | Firm, chewy | Yes | Holds custard well, classic choice |
| Brioche | Soft, airy | Yes | Rich flavor, absorbs beautifully |
| Challah | Slightly sweet | Yes | Soft but sturdy, adds sweetness |
| Sandwich Bread | Soft, thin | No | Becomes soggy, loses structure |
| Fresh White Bread | Very soft | No | Too delicate, results in mushy bake |
How to Make the Perfect French Toast Casserole
If you want an easy breakfast that feels special, this foolproof French Toast Casserole is your answer. Here’s exactly what you need and how to bring it together.
Ingredients
- ½ a loaf of French bread (about 8 oz) cut into cubes
- ½ cup butter
- 1 cup packed brown sugar
- 6 eggs
- 2 cups milk
- 2 teaspoons vanilla extract
- 2 teaspoons cinnamon (divided)
- 1 Tablespoon brown sugar (for topping)
- Powdered sugar for topping (optional)
Instructions
- Preheat your oven to 425 degrees. Butter a 13×9 inch baking pan and set it aside.
- Melt the butter in a small saucepan over medium heat. Stir in brown sugar until dissolved and smooth. Pour this mixture evenly into the prepared pan.
- Add the bread cubes by spreading them over the brown sugar and butter layer.
- Whisk together the eggs, milk, vanilla extract, and 1 teaspoon cinnamon in a medium bowl. Pour this custard mixture over the bread cubes, making sure every piece is soaked. Sprinkle the remaining 1 teaspoon cinnamon and 1 tablespoon brown sugar on top.
- Bake for 25-30 minutes until the top is golden brown. Remove from the oven and optionally dust with powdered sugar before serving. Enjoy!
Tips for a Foolproof Casserole Every Time
- Cut bread into uniform 1-inch cubes so they cook evenly and absorb custard consistently.
- Let the casserole sit for at least 20 minutes, or overnight if possible, to soak up all the flavors and soften perfectly.
- Check for doneness by ensuring the center is set and not jiggly; if needed, bake a little longer covered with foil.
- Using slightly stale bread prevents sogginess and improves texture.
Variations and Substitutions

Troubleshooting Guide: Avoiding a Soggy Casserole
| Problem | Solution |
|---|---|
| My casserole is soggy in the middle | This usually means the bread was too fresh or didn’t soak long enough. Cover with foil, bake 15-20 more minutes. Next time, use stale bread and soak at least 20 minutes before baking. |
