    This Gluten Free French Toast Casserole is super simple to make and so delicious! No one will ever know it is gluten free. This french toast bake has become a weekend special in our home and a go to for special occasions. Unlike traditional french toast, this recipe can be made and prepped in advance so it is one less thing you have to do in the mornings!

    This recipe is a go to in our home. From holiday brunch, Sunday brunch, Christmas morning, to Mother’s Day this recipe is always a huge hit. It pairs well with just about anything. I love making it with my Hashbrown Breakfast Casserole, Protein Overnight Oats, Air Fryer Sausages, Dairy Free Hollandaise Sauce, Blueberry Maple Turkey Breakfast Sausage, Apple Oatmeal Bake, or my Spinach Mushroom Frittata.

    Why I Love This Recipe

    • It has become a go to for weekend brunch. My husband loves it, I love it and kids love it too!
    • You can turn this recipe into an overnight french toast casserole. This make-ahead dish can be prepped the night before (which I highly recommend if you are hosting or having it on a holiday morning) by putting everything together in a casserole dish then just baking it the morning of. You can prep it 2-3 days in advance. 
    • This recipe is naturally gluten free, refined sugar free, dairy free, soy free, nut free and can be made grain free if you use grain free bread. 
    • No one will even know this recipe is a gluten-free version! It takes just like the real thing. 
    • This recipe can easily feed a crowd and is so easy to make in bulk. 
    • Unlike traditional baked french toast casserole, this recipe does not have any processed sugars in it!

    Simple Ingredients

    French toast ingredients laid out in small glass bowls on the counter.
    • Gluten free bread-Any kind will work. Be sure to cut the bread into small 1 inch bread cubes. My favorite is the bread from our local meal prep company, it is so good! We ship it nationwide. You can check out our ordering website here. 
    • Maple syrup-I like the Kirkland brand. Make sure whatever brand you have it is pure maple syrup. I use this in this recipe in place of brown sugar. It is better for you and keeps this gluten-free french toast casserole moist.  
    • Eggs-This acts as the base of the french toast custard mixture. 
    • Full fat whole milk-This enhances the creaminess in the custard mixture.
    • Melted butter-This helps keep this french toast casserole moist and gives it that buttery taste.  
    • Cinnamon-This enhances the flavor even more. 
    • Vanilla extract-For flavor.

    See the recipe card below with a full list of ingredients and measurements.

    Recipe Substitutions and Variations

    • Bread-You can also use cinnamon raisin bread if you want to spice this recipe up! Any kind of gluten-free bread would work. 
    • Milk-If you are dairy free like myself you can also use non-dairy milk. Full-fat coconut milk will mimic the whole milk flavor and richness the most. Unsweetened almond milk will also work as well. You can also use heavy cream if that is your thing. 
    • Butter-If you are dairy free like myself you can also use ghee or dairy-free butter. I have a recipe up on my blog for how to make your own Homemade Ghee too!
    • Fresh berries-You can jazz up this recipe by fresh berries into the mixture. Fresh blueberries and fresh strawberries are my favorite!
    • Banana-I love adding banana slices on top to serve. 
    • Bacon-Totally not necessary, but this is my husband’s favorite part! I love adding cooked bacon into the mix. Check out my Instant Pot Bacon Recipe or my blog post on the best way to Cook Turkey Bacon.

    This recipe has not been tested with any other substitutions or variations. If you try something else out please let me know how it turns out in the comments below!

    Recipe Instructions

    All french toast wet ingredients in a large glass bowl.
    Step #1: First, whisk together all of the ingredients aside from the bread in a large bowl to make the custard mixture. Make sure the butter is melted. 
    Cubed bread in a pan with french toast custard drizzled on top.
    Step #2: Next, in a baking dish, add in the cubed bread in the casserole dish then slowly pour the egg mixture over top. 
    Now, allow the casserole to sit with a lid on for at least two hours to allow it to set. 
    Then, preheat the oven to 350 degrees F. 
    Bake the casserole for 30 minutes or until it is golden brown on top and done in the middle. 

    Recipe Tips and Tricks

    • Tip #1: If time permits, it is better to leave the bread out so it is a little stale! The dryer the bread, the better the casserole will be!
    • Tip #2: If you have extra time, allow the casserole to soak overnight. This will ensure your casserole is nice and fluffy!

    Recipe FAQs

    What kind of toppings can I add?

    I love fresh fruit, bananas, and even chocolate chips! You can even drizzle my Seedless Raspberry Jam on top too.

    Can I freeze french toast casserole?

    Yes, however, it tastes best fresh. If you do freeze it, make sure it is sealed in plastic wrap plus a freezer container so that it does not get freezer burnt.

    How long does this recipe last?

    This recipe can last in the fridge for up to 6 days in an airtight container.

    Can I use regular bread?

    Yes! If you do not have a sensitivity to gluten or do not have celiac, you can use regular bread. French bread or sourdough would be perfect for this recipe.

    How can I reheat french toast casserole?

    This casserole can reheat quickly in the microwave for 30 seconds or in the oven for 5-10 minutes at 350 degrees.
