Sourdough French Toast Casserole

This sourdough French toast casserole is one of the most delicious and most versatile breakfasts that I’ve ever tried! It’s a sweet and satisfying spin off of my other delicious recipe, Maple Cinnamon Sourdough Bread. And while this is of course most delicious with that bread specifically, you can adapt this to use your favorite bread recipe, or even a store-bought bread! Also, the best French toast toppings to make it seasonally enjoyable are below. Keep reading to see how to make the best sourdough French toast casserole that you’ve ever had!

Why Sourdough French Toast

In my post about how to make a sourdough starter, you can see how many benefits there are to using sourdough in your recipes as opposed to commercialize yeast!

The colony of yeasts in a sourdough starter is a natural probiotic, making it gut healthy. It is also much easier to digest because the grains (flours) are partially broken down, which leaves less work for your digestive system to do!

In addition to these benefits, sourdough contains a variety of vitamins such as calcium, magnesium, folate, potassium, niacin, antioxidants, and more.

And of course, one of my favorite benefits is…it tastes so much better! Now that I’ve had sourdough bread as part of my regular meals, I don’t think I could ever go back to store-bought bread. It just lacks flavor and personality. Give sourdough a try, and you won’t regret it!

Can I make this ahead of time?

Yes! You can assemble this sourdough French toast casserole up to 1-2 days before baking. Be sure to store it in the refrigerator until you’re ready to bake it.

Substitutions

  • You may substitute a regular (homemade or store bought) loaf of bread for the one called for in the recipe. If you substitute a plain loaf though, consider adding an extra 1/4 cup of brown sugar to the butter mixture and 1 tsp. ground cinnamon to the egg mixture before assembling the casserole. This will make up for the cinnamon and sweetness lost from the bread substitution.
  • You may substitute white sugar instead of the brown sugar if desired.
  • For a creamier casserole, you can swap half and half instead of the milk.
  • In a pinch, you can omit the vanilla extract without a significant loss of flavor.
