Keto French Toast Casserole is the breakfast casserole you are dreaming of. This incredible french toast has a comforting bread layer, cream cheese filling, creamy custard, and a crumb topping. It’s completely keto, low-carb, gluten-free, and grain-free!

French toast is the breakfast of champions, right? Okay, maybe not, but it is DELICIOUS and the best way to start the day. We don’t eat this keto french toast casserole all the time, but it’s a total treat when we do.

You can whip it up for breakfast of course, but it also makes a lovely brunch recipe too. It’s sweet, but we don’t actually use any refined sugar, just powdered erythritol and brown sugar sweetener. They are the perfect combination to give you that amazing French toast that we all are accustomed to and love.

Brunch is my favorite meal of the week and we love having an assortment of sweet and savory such as my Keto Eggs Benedict Casserole or my Sausage and Egg Pie, Low Carb Cinnamon Roll Cake or Almond Crumb Cake, some bacon, and fresh berries.

What You’ll Need To Make French Toast Casserole

There are four key components to this keto french toast recipe. First, is the low carb bread, then a sweet cream cheese filling. Next are a creamy custard and crumb topping.

Despite this having 4 parts it only has 12 ingredients and they are all common ingredients you probably have already if you've done any low carb baking in the past. And the recipe comes together quickly!

Almond flour - I find the flavor of almond flavor mild enough that it is a great low carb choice for both sweet and savory recipes.
Baking powder - Always check the date!
Brown sugar sweetener - You can make a white sugar sweetener into a brown sweetener just by adding 1 tsp of molasses per cup.
Butter - Coconut oil is a good sub if you run out.
Cinnamon - Or sub in pumpkin spice for a fall flavor!
Coconut flour - Coconut flour works well in combination with almond but can be hard to use on its own. I do not recommend using all coconut flour in this recipe.
Coconut milk - From the carton. Or any unsweetened plain nut milk.
Cream cheese - Other delicious choices are ricotta cheese or mascarpone.
Eggs - They are a must in this. They are the binding agent in the bread and thickener in the custard.
Heavy cream - Full-fat canned coconut milk can work for dairy-free.
Powdered erythritol - You only need a little bit. If you don't have any just sweeten the cream cheese to taste with whatever you have on hand.
Vanilla - Standard in baking and enhances the flavor of everything. Almond extract is another nice choice.

How To Make Keto French Toast Casserole

There are only a handful of steps and nothing too hard to make this incredible breakfast casserole. Let’s take a look at the easy-to-follow steps:

First Step: Begin by warming the oven to 350 degrees.

Second Step: Combine the butter, almond flour, coconut flour, eggs, coconut milk, and baking powder for the gluten free keto bread.

Spread the batter out into an 8x8 baking dish and bake for 20-25 minutes. Let the bread cool for 10 minutes, then cut it into cubes. You don't need to wash the baking dish because the bread is going right back into it!

Expert Tip: This is based on a 90 second bread I use in my Keto Grilled Cheese. If you are in a hurry you can just microwave the bread instead of baking it!

Expert Tip: You can prepare the bread a day ahead of time. This is great if you are making the french toast casserole for holidays or an event.

Third Step: Combine the vanilla, cream cheese, and powdered erythritol for the cream cheese filling until smooth. Put the cubes of bread into the baking dish and add cream cheese dollops on top.

Fourth Step: Prepare the custard by combining the eggs, coconut milk, brown sugar sweetener, heavy whipping cream, and cinnamon together. Gently pour the custard over the top of the bread.

Fifth Step: Cut the butter into the flour, sweetener, and cinnamon until you end up with a crumb for the topping. Sprinkle the crumbs on top of the casserole.

Sixth Step: Bake the keto breakfast casserole for 40-45 minutes or until it is golden brown and the center has set up. Serve with some sugar-free maple syrup and enjoy!

Can I Double This Recipe?

Yep! Of course, you can double this keto breakfast casserole recipe! Simply replace the 8x8 pan with a 9x13 pan and double the ingredients. Everything else should remain the same. The cook time may end up being a few minutes longer, so check it when the time is almost up.

Is It Add Fruit to the Keto French Toast Casserole?

Yes, adding fruit is a lovely way to add more flavor and color to the low carb french toast casserole. I recommend sticking with berries, so it stays low carb. Strawberries and blueberries are so yummy with the cream cheese and custard layers.

Can I Add Nuts?

Sure! If you add some nuts, it will have a yummy crunch to it. I recommend pecans or walnuts because they are so tasty with french toast. But, you can really add any kind of nut that you enjoy.

How Do You Store Leftovers?

For best results, let the low carb keto french toast cool down, then put inside of a food container that’s sealed well. Place in the fridge for up to 5 days. Or in the freezer for up to 2 months. Warm-up in the microwave or oven.

What Syrup Should I Use?

I recommend using a naturally sweetened sugar free maple syrup. This keto breakfast casserole is lightly sweetened on its own and really does need either a sugar free syrup, sugar-free jam, or some powdered sweetener on top.
