Ingredients

  • 1 (15 oz) loaf dry or slightly stale gluten-free bread* cut into 1-inch cubes (you'll have about 9-10 cups cubed bread) (I like Canyon Bakehouse for this!)
  • 5 large eggs
  • 2 cups milk regular or dairy-free milk: I use unsweetened almond milk
  • 1/3 cup pure maple syrup white sugar, or brown sugar
  • 2 Tablespoons butter or vegan butter melted
  • 1 Tablespoon vanilla extract
  • 2 teaspoons ground cinnamon
  • 1/8 teaspoon salt
  • OPTIONAL TOPPINGS: pure maple syrup powdered sugar, fresh berries, sliced peaches, toasted pecans, sliced almonds, etc.

Instructions

TO MAKE THIS CASSEROLE THE NIGHT BEFORE:

  • Prep Your Pan. Grease a 9x13" (3-quart) baking dish with a little butter or spray oil.
  • Prep Bread. Place dry bread cubes in the prepared baking dish.
  • Make The Custard Mixture. In a medium bowl, whisk together eggs, milk, syrup/sugar, melted butter, cinnamon, vanilla, and salt. (The cinnamon may look a little clumpy. Don't worry!)
  • Pour the egg/milk mixture over the bread in the baking dish, doing your best to evenly coat the bread. Use a spatula to *gently* pat down the bread so it's all coated in the egg mixture.
  • Cover & Chill. Cover the baking dish with aluminum foil and refrigerate 8-12 hours overnight in the refrigerator.
  • The Next Morning, Preheat the oven to 350 degrees F and let the casserole come up to room temperature while the oven preheats.
  • Bake. Place the baking dish in the oven and bake 30 minutes covered.
  • Remove the foil and bake the French toast casserole an additional 15-20 minutes or until the top is golden.
  • Cool 5 minutes or so, then cut into slices + top with powdered sugar or your favorite garnishes.

TO MAKE THIS CASSEROLE RIGHT AWAY (SAME MORNING)

  • Preheat & Prep Your Pan. To start, preheat the oven 350 degrees F. Grease a 9x13" (3-quart) baking dish with a little butter or spray oil.
  • Prep Bread. Place dry bread cubes in the prepared baking dish.
  • Make The Custard. In a medium bowl, whisk together eggs, milk, syrup/sugar, cinnamon, vanilla, and salt. (The cinnamon may look a little clumpy. Don't worry!)
  • Pour the egg/milk mixture over the bread in the baking dish, doing your best to evenly coat the bread. Use a spatula to *gently* pat down the bread so it's all coated in the egg mixture.
  • Cover, Rest & Bake. Cover the baking dish with foil and let rest 20-30 minutes before baking. Bake COVERED 30 minutes.
  • Remove the foil and bake the French toast casserole an additional 15-20 minutes UNCOVERED or until the top is golden.
  • Cool 5 minutes or so, then cut into slices + top with powdered sugar or your favorite garnishes.

Notes

  • *HOW TO DRY BREAD FOR FRENCH TOAST CASSEROLE: If your bread isn't dry, you can leave it out overnight or all day to dry, or pop it in a 200 degree oven on a baking sheet for about 10 minutes to speed things along. Let the bread cool completely before proceeding with the recipe.
  • Budget-Friendly Tip! I like to save all the ends of my bread loaves over a few weeks, then use them all for this when I get enough. My kids won't use the ends for sandwiches or toast, but they'll happily eat them in this gluten-free French toast casserole!
  • Tips For Leftovers. Cover the pan with foil or transfer slices of the casserole to an airtight container and store in the fridge 1-2 days. Reheat in the microwave, or place the entire pan in a 300 degree oven for 15-20 minutes to reheat.
