Gluten Free French Toast Casserole

Overnight Gluten Free French Toast Casserole

This delicious gluten-free French toast casserole is the perfect easy breakfast for a special occasion (or any day!). It is an easy breakfast to throw together the night before and pop in the oven when you wake up. It is gluten and dairy-free and so delicious.

For this recipe, you can sub in any additional add-ins if you aren’t a blueberry fan. Or omit them if you want a more traditional French toast taste. It tastes great as a blueberry french toast bake, strawberry french toast bake, or even chocolate chip french toast bake.

When this gluten and dairy-free french toast casserole is ready, it tastes great on its own, topped with syrup, or topped with dairy-free cream and additional blueberries (or other add-ins). It can be made in so many different combinations yet it is amazing every which way!

Tips for Success

*This recipe works best if you let the bread sit in the egg mixture overnight. This will help it to soak up as much of the mixture as possible and prevent it from getting dried out.

*You are able to use a number of different add-ins instead of the blueberries. This recipe tastes great with strawberries, raspberries, dairy-free chocolate chips, or pecans, and more. It also tastes great as is, with no add-ins.

*When cooking, cook for around 50 minutes at 350 degrees. Start checking to see if the top is browned and the inside is cooked through. Ovens tend to vary a bit so you may find it is looking done around 45 minutes. You may also find your oven takes a little bit longer and doesn’t finish for closer to an hour.

*If there are leftovers simply heat them up in the oven at 350 degrees for 10-15 minutes. The microwave for 60 seconds works as well but it changes the texture a bit.

Casserole Base Ingredients:

  • 1 15oz loaf gluten-free bread (we like to use honey oat bread)
