The #1 Tip for Making This Gluten-Free French Toast Bake

Just like every similar recipe, ensure your gluten-free bread is thoroughly toasted before starting this recipe. Dried-out bread soaks up the custard mixture better and is less likely to be soggy.

Frequently Asked Questions

Why Is My French Toast Casserole Soggy?

Your gluten-free bread was likely not dried out enough. Dried-out bread soaks up the custard mixture better, allowing for crispier edges.

How Do I Dry out Bread for French Toast?

Grease your baking dish, add 1” bread cubes, and bake for 5-7 minutes (right until it starts browning).

Can I Substitute Whole Milk for Plant Milk?

Instead of dairy milk, you can use a milk substitute so long as it creates a custard-like mixture. You can consider heavy cream, almond milk, coconut cream, or thicker plant-based milk.

Can I Use Regular Bread?

Yes, you can use regular bread in this recipe if you do not need a gluten-free dish.

Can You Make French Toast Casserole in Advance?

You can make all of the separate elements and store them until the next morning. Toasted bread cubes should be kept at room temperature. The custard should be covered and refrigerated. In the morning, combine and cook as recommended.

Can You Make Gluten-Free, Dairy-Free French Toast Casserole?

Absolutely. Instead of melted butter, you can use coconut oil. Instead of whole milk, choose a thick plant-based milk of your choice.

Can You Make This Gluten-Free French Toast Vegan?

Making French toast casserole vegan will be a bit difficult due to the six eggs required by this recipe. If you have success, please let us know in the comments!

How Do I Store Gluten-Free French Toast Casserole?

This casserole should be stored in an airtight container and can be refrigerated for up to 48 hours.

Can I Freeze This Gluten-Free French Toast Casserole?
