Ingredients

Scale

French Toast Casserole

  • 8 large eggs
  • 3 cups half and half
  • ¼ cup dark brown sugar, packed
  • ½ tablespoon vanilla extract
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon ground nutmeg
  • ½ teaspoon salt
  • 1 (12-16 oz) baguette, cubed into 1-inch chunks (preferably at least 1 day old)

Crumble

  • 2 cups old fashioned oats
  • 2 cups all-purpose flour
  • 1 cup pecans, roughly chopped
  • 2 cups dark brown sugar, packed
  • ½ tablespoon ground cinnamon
  • ½ teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup unsalted butter, melted

Toppings (Optional)

  • Maple syrup
  • Strawberries, sliced
  • Whipped cream

Instructions

  1. Prepare Baking Dish: Grease a 9×13 inch baking dish with cooking spray and set it aside.
  2. Mix Wet Ingredients: In a very large bowl, whisk together the eggs, half and half, brown sugar, vanilla extract, ground cinnamon, ground nutmeg, and salt until fully combined.
  3. Add Bread: Gently fold the cubed baguette pieces into the egg mixture, ensuring the bread is evenly coated.
  4. Refrigerate Overnight: Pour the mixture into the prepared baking dish, cover tightly with aluminum foil, and refrigerate overnight or for at least 4 hours to allow the bread to soak and flavors to meld.
  5. Preheat Oven & Prepare Crumble: Preheat your oven to 350ºF (175ºC). Remove the casserole from the refrigerator and take off the foil. In a large bowl, mix together rolled oats, all-purpose flour, chopped pecans, brown sugar, ground cinnamon, baking powder, baking soda, salt, and melted butter until the mixture is evenly combined and crumbly.
  6. Add Crumble Topping: Evenly sprinkle the crumble mixture over the surface of the soaked bread casserole.
  7. Bake: Bake uncovered for 40 minutes in the preheated oven, until the casserole is puffed up and the crumble topping is golden and crisp.
  8. Serve: Remove from the oven and serve warm topped with optional maple syrup, sliced strawberries, and whipped cream if desired for added sweetness and flavor.

Notes

  • Use day-old baguette or bread for best texture to absorb the custard without becoming mushy.
  • The casserole can be refrigerated for up to 4 days before baking.
  • You can freeze the baked casserole for up to 2 months; reheat in microwave or oven until warmed through.
  • Feel free to substitute pecans with walnuts or almonds based on preference.
  • Adjust cinnamon and nutmeg amounts to taste for a more or less spiced flavor.
