Baked French Toast

  • 1 bakery-style loaf of sourdough bread
  • 1 cup chopped pecans
  • 8 large eggs
  • 1/2 cup full-fat Greek yogurt
  • 1/2 cup maple syrup
  • 2 teaspoons ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1.5 cups milk (any kind)

Streusel Topping

  • 1/3 cup white whole wheat flour
  • 1/2 cup chopped pecans
  • 1/4 cup brown sugar (or coconut sugar)
  • 4 tablespoons butter, room temperature (or coconut oil)


  1. Preheat oven to 350ºF and spray a 10 x 7-inch casserole dish* with cooking spray.
  2. Use a knife to chop your sourdough into bite-sized pieces around 1 to 1.5-inches wide. If your sourdough is fresh from the bakery, it might be easier to tear the pieces apart with your hands. Transfer bread into casserole dish.
  3. Then, sprinkle on 1 cup of chopped pecans and toss with sourdough pieces.
  4. In a large bowl, whisk together eggs, Greek yogurt, maple syrup, cinnamon, nutmeg, and milk.
  5. Pour egg mixture on top of sourdough and use your hands to press the bread into the egg mixture, submerging it. You want to make sure you do this to fully coat all pieces of bread.
  6. Place in refrigerator overnight OR for at least 30 minutes if you’d like to bake it immediately.
  7. Make streusel topping by mixing together white whole wheat flour, chopped pecans, brown sugar, and butter. Combine to form a crumble, not a paste. This will depend on how soft your butter is, so make sure not to fully melt it.
  8. Remove French toast bake from the refrigerator and use your hands to submerge the bread in the egg mixture one more time before baking. Cover with tin foil and bake at 350ºF for 30 minutes, covered. Remove and add streusel topping. Bake for another 15-25 minutes, uncovered depending on how wet you like your French toast.
  9. Let cool for at least 5-10 minutes before slicing.

Tips & Notes

  • Option to use a store-bought loaf that is used for sandwiches. Make sure to measure out 8 cups.
  • If you’re using a bigger casserole dish (such as a 9×13-inch), you’ll likely need to reduce the bake time by 5-10 minutes.
  • Nutrition is for 8 servings.
