What is a French Toast Casserole?

Think of all the goodness in a traditional French Toast. Throw it all together in a baking dish and bake and you’ve got French Toast Casserole. This is an easy way to serve a crowd for breakfast. 

I’ve added blackberries to this delicious breakfast to add even more delicious taste.

Ingredients for making French Toast Casserole.

Weekend breakfasts are a big deal in our house. We often have pancakes or waffles, banana muffins, or English muffin sandwiches. We love to eat breakfast! This baked French toast with blackberries was a huge hit with my kids! 

Ingredients needed:

  • French bread
  • Milk
  • Eggs
  • Sugar
  • Vanilla
  • Cinnamon
  • Nutmeg
  • Blackberries

What fruit can I add?

I used frozen blackberries. You can also use fresh blackberries. Other fruit you could use include fresh or frozen blueberries, raspberries, strawberries, huckleberries, and peaches. Use the same amount of fruit called for in the recipe. 

If using frozen fruit, do not thaw fruit before using. 

French bread cut up for French Toast Casserole.

To make this breakfast casserole you’ll start with a loaf of French bread. The best is to use a day old loaf of bread, not a super fresh one. If your loaf is extra fresh, cut up the bread and let it sit out for a bit. 

You want these bread cubes just slightly stale or dry. This helps absorb the custard mixture a bit more without losing the texture of the bread.

Can I make this the night before?

Yes, you can make this an overnight French toast. I made this in the morning. You do want everything to rest for at least 30 minutes before baking so all the custard gets absorbed into the bread.

To make this the night before, follow directions in recipe. Add the mixture to a baking dish, cover and refrigerate overnight. 

Pull out casserole dish and let sit at room temperature while your oven is preheating. Increase baking time by 15 minutes.

How long do you bake French Toast Casserole?

Baking time can vary depending on the size of your casserole dish. Bake in a preheated 350 degree oven for 55-60 minutes. Increase baking time by 15 minutes if casserole was refrigerated. 

To check if you casserole is done, look for browned tops and a set middle. Give the baking dish a little jiggle. If the center is wiggly, the custard hasn’t cooked through yet. Just pop in for another 5-10 minutes. 


Don’t forget to PIN for later!

Recipe Notes

This recipe works best with an older loaf of bread. If yours is soft and fresh, just let the cut pieces dry slightly before adding to the custard mixture. 


Fresh or frozen berries can be used. If using frozen, do not thaw before adding. 


To check if casserole is cooked through, give the pan a little jiggle. If the center is wiggly, the custard isn't cooked. Pop back into the oven for an additional 5-10 minutes.

    Hi Kathy
    If making this dish overnight, will I still be able to use frozen fruit since you suggest to not thaw the fruit if using frozen.

      Hi Jackie,
      You can still use frozen fruit and make it ahead of time.
