HOW TO MAKE THE BEST KETO FRENCH TOAST CASSEROLE

While I don’t usually eat breakfast during the week, I am still a fan of breakfast foods and enjoy a big breakfast on Saturday mornings with my family. Often we will stick to just eggs and bacon, but sometimes it is nice to have a little variety like this Keto Blueberry French Toast Casserole. Even though it looks a bit fancy, it is effortless to make. 

Making a keto french toast simply requires a few of the swaps you’d normally make when baking on a low carb and sugar diet. As long as your bread is keto and the sweeteners used are keto-friendly, you’re on your way to perfect low carb french toast! For this keto french toast, I started off by making my Keto Homemade Blueberry Bread. It’s the perfect bread for a blueberry french toast bake. I did adjust the recipe for this breakfast casserole, since a french toast bread must be drier in order to soak up all of the custard.

Ingredients for Blueberry Keto French Toast:

  • Coconut flour – If you prefer using almond flour, keep in mind that the ratio is ¼ cup coconut flour = 1 cup almond flour, not a 1:1 substitution.
  • Swerve Granulated or Monkfruit Classic – Whichever keto sweetener you have on hand works great for this recipe.
  • Lakanto Sugar-Free Maple Syrup – What would french toast be without the maple syrup drizzle?! I love using this maple syrup whenever I’m enjoying a sweet pancake, waffle, or french toast breakfast.
  • Monkfruit Powdered – This is optional, but I recommend it for sprinkling on top of the casserole before serving. 
  • Blueberries – These little blue berries give this keto french toast that perfectly sweet and fruity taste. I definitely recommend using fresh berries, not frozen.
  • Cream cheese – Dots of cream cheese keep the casserole super moist and flavorful. Yum!
  • Pecans – The nuts throughout this keto french toast casserole give it a wonderful crunch and flavor. Feel free to omit these if you’re allergic, of course!
  • Cinnamon and vanilla – In my opinion, french toast wouldn’t be french toast without the aromatic flavors of cinnamon and vanilla.

How to make this keto french toast recipe:

Sliced loaf of keto blueberry bread

Step 1: Preheat your oven to 350 degrees and grease a 9 X 13 casserole dish. Next, make my Homemade Keto Blueberry Bread recipe (without the glaze). However, be sure to leave out 1 of the eggs and the heavy whipping cream because you will need a bread that is a bit more sturdy to make the French Toast Casserole.

Step 2: Slice the bread into 12 equal slices and place on a cookie sheet in the oven. Bake one side for 10 minutes at 300 degrees then turn the bread over and bake the other side for 10 min. The purpose is to dry out the bread but not to brown it. Allow the bread to cool then cut up into small cubes. Spread out the blueberry bread cubes in the bottom of the casserole dish.

Step 3: Combine the heavy whipping cream, eggs, vanilla, and cinnamon in a bowl and beat with a mixer on medium/high until thoroughly combined.

Step 4: Drop the chopped pieces of cream cheese on top of the blueberry bread. Make sure to space them out evenly. Pour the egg mixture on top. Finally, sprinkle chopped pecans on top of the Keto Blueberry French Toast Casserole.

Step 5: Bake for 23-30 minutes or until it reaches desired doneness. Serve with sugar-free Lakanto Maple Syrup. You can also sprinkle Monkfruit Powdered on top if desired.

CAN YOU MAKE THIS KETO FRENCH TOAST CASSEROLE THE NIGHT BEFORE?

I’ve had several of you ask if the Low Carb Blueberry French Toast Casserole can be made the evening before and then baked the next morning. I do not think that it would hold up soaking overnight in the egg mixture. My advice is to bake your bread the night before to save some time the morning of. You could get the casserole ready and leave the egg mixture in a bowl, then combine the two before baking.

HOW DO YOU STORE KETO BLUEBERRY FRENCH TOAST CASSEROLE LEFTOVERS?

I stored my leftovers in the fridge, which worked out very well. It should keep for about a week in the fridge — if it lasts that long! If you need to store the keto french toast leftovers for longer, I would recommend freezing it for up to 6 months. To save space in your freezer, cut squares out of the casserole, place them neatly in a freezer bag, and stow that in the freezer. I find it helpful to label my freezer bags with the name of the food and the date so that I know what’s what and when things should be thrown out.

CAN YOU OMIT THE BLUEBERRIES FROM THIS RECIPE?

Not a blueberry fan? Don’t have any on hand and can’t get to the store? Not a problem! You can absolutely leave out the blueberries when making the keto blueberry bread at the beginning of this recipe. It won’t have that same balance of sweet, fresh, and fruity flavor, but it will still be delicious. Alternatively, you could sub in a berry you do like in place of the blueberries.

  1. I love the blueberry bread. Have you ever done it with orange and cranberries for the holidays? I’m going to try this recipe for Christmas morning.

  2. Hi Kasey – This looks delicious! Do you have a suggestion for how to make this without berries? The recipe calls for 3/4 cup but my husband doesn’t like berries. Would it affect the recipe to follow it as written but omitting the berries? Not sure if there would need to be something else added for bulk. Looking forward to trying this next weekend with company!

    1. Hmmmmm…I’m not sure as I’ve only made it as is. I have a pumpkin bread recipe that should work for this if he likes pumpkin.

    2. Donna, I just made this without blueberries simply because I didn’t have any and it turned out perfect! Great receipe, thank you!

  3. 4 stars
    How to tell if it’s done baking? What should I look for? I baked it for 30min, and it was still pretty liquidy in the center.

    1. The center will begin to set up. You’ll know it is ready then. Each oven bakes differently so you just have to watch it.

  4. I live in a high altitude area. My blueberry bread came out very greasy, the blueberries sank and it was a fail. Do I need to adjust the flour for the altitude?

    1. Typically recipes have to be adjusted for high altitudes. However, I am not familiar with the adjustments as I don’t live in a high altitude area so I can’t test recipes to know what needs to be converted.

    1. I’ve only fixed the recipe as is. I would think boxed blueberry bread would not be keto friendly.

  5. 5 stars
    I really appreciate your effort with coconut flour recipes. I made this recipe for my family birthday brunch. It was a hit with both keto and non-keto family members.
