Helpful tips

Make sure the bread is a day old, dry and crusty. It helps to cut the bread into cubes and let them sit uncovered on a baking sheet for a few hours to dry out. When the bread is dry, it will soak up the liquid ingredients and make for a tender, flavorful casserole.

Use the full 8 hours or ideally overnight to let the casserole soak. The longer it sits, the more flavorful the casserole will be.

Frequently Asked Questions

What bread is best for french toast casserole?

French bread is my favorite as it has a nice crust, but sourdough, brioche or Italian bread may be used instead.

Can you freeze french bread casserole?

Yes, it helps to bake the casserole in an aluminum dish for easy freezing. After the casserole is baked, allow it to cool completely. Wrap the entire dish in aluminum foil to prevent freezer burn. Freeze for up to 3 months. To defrost, bake uncovered at 350 F for 30 minutes.

Can you use gluten-free bread?

Yes, gluten-free bread may be used in this recipe. You can also use dairy-free milk and heavy cream.

Why is my French toast casserole soggy?

Either there wasn’t enough bread to soak up all the liquid or the casserole wasn’t baked long enough. Thick, dry bakery bread is best for this recipe.

Ingredients

  • 1 loaf (12 ounces) day-old crusty French bread
  • 8 large eggs
  • 2 cups (480 ml) whole milk
  • ½ cup (120 ml) heavy cream
  • ¾ cup (150 g) brown sugar, divided
  • ½ cup (100 g) granulated sugar
  • 1 tablespoon pure vanilla extract
  • ½ teaspoon ground cinnamon

Instructions 

  • Spray a 3-quart baking dish with non-stick spray (or grease with butter).
  • Cut the bread into cubes and evenly distribute them in the pan. In a large mixing bowl, whisk together the eggs, milk, heavy cream, ½ cup brown sugar, granulated sugar, and vanilla. Pour the mixture evenly over the bread, then sprinkle the cinnamon evenly over the top.
  • Cover the pan tightly with plastic wrap and chill in the refrigerator for 8 hours, or overnight if possible (for best flavor).
  • When ready to bake, remove the casserole from the refrigerator and take off the plastic wrap. Preheat the oven to 350 degrees F.
  • Sprinkle the remaining brown sugar on top of the casserole. Bake for 45-60 minutes, until golden brown and baked through. Serve with syrup and fresh fruit, if desired.

Notes

Bread: French bread is best, but any bakery bread will work. I suggest brioche, sourdough or Italian bread. Be sure it is dry and crusty. You can cut it into cubes and let the bread sit on a baking tray for 12 hours to speed up this process if it is fresh bread.
Leftovers may be kept in an airtight container in the refrigerator for up to 2 days or frozen.
Freeze french toast casserole after it is baked and cooled completely. Wrap securely and freeze for up to 3 months. To defrost, bake casserole uncovered at 350 F for 30 minutes.
