Ingredients needed

  • Slices of sourdough bread, ideally a few days old or slightly stale

Substitutions

If you don’t have some of the suggested ingredients or you would like to make some adjustments, here are a few of my recommended substitutions:

  • Homemade sourdough bread
    • If you prefer to make your own sourdough bread instead of using store-bought, way to go and all the power to you!
  • Whole milk
    • I typically use 2% dairy milk but if you would rather use whole milk, this will just make the mixture even creamier – delish!
  • Plant-based milk
    • Using a plant-based milk in this recipe will absolutely work! My favourite is soy milk because it provides similar amounts of protein per serving as dairy milk. Almond or oat milk provide much less protein. However, in terms of accessibility and ease, use whatever one you like and have available.
  • Nut butter
    • Instead of Biscoff, you can absolutely incorporate a nut butter. Peanut butter, almond butter, cashew butter, pistachio butter… these would all be absolutely scrumptious in this recipe!
  • Brown sugar, maple syrup or honey
    • If you like a sweeter french toast, feel free to add 1-2 teaspoons of brown sugar, maple syrup or honey into the wet ingredients before blending.

 

How to make Biscoff Sourdough French Toast

Now that we have all of the ingredients, or substitutions, together, let’s get started on making the french toast!

  1. Place the eggs, milk, Biscoff spread, vanilla extract and cinnamon in a blender and blend on high until the mixture is smooth. This typically takes roughly 10 seconds, depending on the power of your blender.
  2. Place this egg mixture in a shallow baking dish, big enough to fit a piece of bread.
  3. Start with one of the slices of sourdough bread and dip it in the egg mixture, soaking up the moisture for about 10-20 seconds. Flip and repeat on the other side of the bread.
  4. Grease a frying pan or skillet with butter or cooking spray over medium heat. 
  5. Transfer the soaked piece of bread to the prepared pan or skillet and cook for 3-4 minutes on each side, or until golden brown. If your pan or skillet is large enough, you may be able to fit and cook multiple slices of sourdough at the same time.
  6. Once all of the bread is cooked, transfer to a clean plate, top with your desired ingredients and enjoy!

Make it into a french toast casserole!

If you want to mix it up from the classic french toast and create a french toast casserole instead, here’s how to do that! 

  1. Preheat your oven to 350°F and grease an 8”x8” baking dish with butter or cooking spray.
  2. Place the eggs, milk, Biscoff spread, vanilla extract and cinnamon in a blender and blend on high until the mixture is smooth. Pour this into a large bowl.
  3. Rip or chop the crusty sourdough bread into slightly larger than bite sized pieces and toss them into the wet ingredients until all of the bread is torn apart and in the bowl. Using a wooden spoon, mix the bread into the egg mixture until each piece of the bread is soaked through.
  4. Transfer this to the greased 8×8” baking dish and sprinkle a pinch of brown sugar evenly across the casserole. Bake for 30-40 minutes uncovered, or until the bread has started to turn a golden brown and there are some crispy pieces. Let the casserole cool for 5 minutes before you serve it. Finish it off with your desired toppings and enjoy!

FAQ

  • Can sourdough be used for french toast?
    • Absolutely! Sourdough has a crunchy and crispy crust with soft dough on the inside so it makes a great bread to soak up the egg mixture and isn’t soggy when it’s cooked.
  • Should I toast my bread for french toast?
    • Ideally, the bread you use is a few days old or a little stale. This way, the bread will soak up a lot of the egg mixture. However, if you have fresh sourdough bread, you can always very lightly toast it before soaking it in the wet ingredients.
  • How do you make french toast crispy and not soggy?
    • To make sure your French toast stays crispy, there are a few considerations:
    • Don’t soak the bread for too long! I recommend about 10-20 seconds on each side. Soaking for too long will result in an oversaturated bread, which would make it difficult to cook it to the desired texture.
    • When you’re cooking the bread, make sure you don’t overcrowd the pan or skillet. Give each piece of toast at least an inch on all sides. This will help make it crispier.
    • Make sure the pan or skillet is at the correct temperature. If it’s too low, the bread will take forever to cook and it may become too soggy. If it’s too high, the outer edges of the bread can burn but the inside will be mushy. Cooking at medium-low or medium heat is best.
  • Can I make french toast with brown bread?
    • You can absolutely make French toast with brown bread! Follow the recipe as instructed.
  • How do I make french toast for one person?
    • This recipe calls for 4 slices of sourdough bread. Depending on your appetite, this may be enough for 1 person. However, if you want to reduce it further, you can cut the recipe in half and it should work well, making enough for 2 slices of French toast.
  • How do I make french toast for a crowd?
    • Feel free to double, triple or quadruple this recipe to suit your needs!
