Instructions
In a large bowl, whisk together: eggs, whole milk, half and half, maple syrup, vanilla, cinnamon, and salt.
One slice at a time, place the sourdough bread slices into the egg mixture and turn several times to coat well. Place the bread slices in a 9x13 baking dish. If you're using a boule, you should have 3 slices on the bottom, followed by 2 more layers (you'll have 2 slices on top). Pour the remaining egg mixture, evenly, on top. Cover with plastic wrap, and refrigerate overnight.
In the morning, preheat the oven to 400 degrees F. and generously grease a light-colored non-stick sheet pan with butter (preferred) or cooking oil spray.
Set the top layer of bread slices aside and place the bottom layer pieces onto the sheet pan, allowing any excess egg mixture to drip back into the dish. Place the top slices back into the baking dish to soak up any remaining egg mixture and place them onto the sheet pan.
Bake for 8 minutes, flip and brush with melted butter, and bake 6-8 minutes more until puffed and lightly golden.
While warm, brush with melted butter (if desired), and garnish with your favorite toppings. Enjoy immediately for the best texture.
Notes
Tips
Sourdough slicing. I use a boule and slice it into 12 ¾ inch slices (sourdough brioche is also fabulous for this recipe- but I recommend 1" slices for this loaf since it's softer and more delicate to flip). Set aside the 8 larger interior slices of the loaf for the french toast and save the remaining slices for another use.
Bake time. If you are using a boule- you'll want to flip it using a sturdy spatula around the 8-minute mark, and continue baking to your desire doneness anywhere from 6-8 minutes more. If you are using brioche, adjust the bake time slightly and flip around the 6-minute mark and cook 6-8 minutes more, until lightly golden.
Equipment. I recommend a lighter baking sheet for this recipe since French toast is more likely to burn on a dark sheet pan since it absorbs heat faster. I don't recommend using parchment paper because it can stick to the bread. You can swap the butter for cooking spray, if needed.
Don't skip the overnight soak. It's essential for perfect sourdough french toast that has a fluffy interior and crispy exterior texture.
Alternate skillet method. After soaking the sourdough overnight, heat a non-stick skillet or griddle over medium heat, grease it with butter, and cook each slice for 2-3 minutes per side or until golden brown and cooked through.
