Pro Tips for the Perfect Make Ahead French Toast Casserole

  1. Bread Choice Matters: Use day-old bread for best results. The slightly dried-out texture helps the bread absorb the custard without becoming too soggy.
  2. Don’t Skip the Soak: Allow at least 4 hours for the bread to soak up the custard mixture. Overnight is ideal for the best texture and flavor development.
  3. Room Temperature Baking: Remove the casserole from the refrigerator while your oven preheats. This helps ensure even baking.
  4. Customize Your Praline: Feel free to swap pecans for walnuts or almonds in the praline topping, or add a touch of maple extract for extra flavor.

Storage and Reheating

  • Store leftover French toast casserole in an airtight container in the refrigerator for up to 3 days.
  • Reheat individual portions in the microwave for 1-2 minutes.
  • For larger portions, reheat in a 350°F oven for 10-15 minutes until warmed through.

Make Ahead French Toast Casserole FAQs

Can I freeze this French toast casserole?

Yes! Assemble the casserole but don’t bake it. Wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before baking.

What’s the best bread to use?

We love a hearty sourdough, but french bread, brioche, challah, all work best. The key is using slightly stale bread that will hold up to the custard mixture.

How do I prevent the casserole from becoming too soggy?

Use slightly stale bread and ensure your custard mixture isn’t too heavy to prevent it from being too soggy. You want the bread to absorb the liquid without becoming overly mushy.

Can I make this without nuts?

Absolutely! You can skip the pecans and still enjoy a delicious caramelized sugar topping.

How do I know when it’s done?

The casserole should be golden brown on top and slightly puffy. Insert a knife in the center – it should come out clean without liquid custard.

This make ahead baked French toast casserole with praline topping is perfect for holiday mornings, special brunches, or any time you want to make breakfast extra special without the morning stress. The combination of custardy French toast and crunchy praline topping creates an irresistible breakfast that your family and guests will request again and again.

    1. Hi Laura,
      I have not tried to make this and freeze it. It might work. I would be most worried that the bread would end up soggy, but I don’t really know. If you try it, come back and let me know! 🙂

  2. Why not make things heart and vascular healthy ?
    Using plant based ingredients!
    No sugar,salt or oil.
