Ingredient Selection:

  • Bread: The heart and soul of this dish, the choice of bread matters. Opt for a high-quality French bread or a rustic country loaf. The bread’s texture is crucial; you want it to be slightly stale or day-old, as it will absorb the custard beautifully.
  • Eggs: Fresh, large eggs work best for a rich and creamy custard. If you prefer a lighter option, you can use egg whites or a combination of whole eggs and egg whites.
  • Dairy: A blend of milk and heavy cream provides that luscious, velvety texture. Whole milk or half-and-half are great options. For a lighter version, you can use low-fat milk or a milk alternative like almond or oat milk.
  • Sweeteners: Granulated sugar adds sweetness to the custard, while brown sugar creates that irresistible caramelized topping. Adjust the sugar to your taste, or experiment with alternatives like honey or maple syrup.
  • Flavorings: Vanilla extract, ground cinnamon, and a pinch of nutmeg infuse the dish with warmth and depth of flavor. Feel free to get creative with spices like cardamom or a dash of almond extract for a unique twist.

Preparation Tips:

  • Bread Slicing: When slicing the bread, aim for roughly 1-inch thick slices. This thickness allows the bread to soak up the custard without becoming too mushy.
  • Soaking Time: The key to a perfect French Toast Casserole is allowing it to rest in the fridge overnight or at least 6 hours. This long soak lets the flavors meld and ensures a creamy, custardy center.
  • Topping: The butter and brown sugar topping create a delightful crunch and caramelization. Ensure it’s evenly distributed for a consistent layer of sweetness.

Variations and Substitutions:

  • Fruit Additions: Elevate your casserole by layering in sliced bananas, berries, or apple slices before pouring the custard. This adds a fruity burst to each bite.
  • Nutty Crunch: Sprinkle chopped nuts like pecans or almonds on top of the brown sugar layer for extra texture and flavor.
  • Chocolate Lover’s Delight: Chocolate chips or chunks can be folded into the bread layers for an indulgent twist.
  • Vegan Option: To make it vegan, substitute eggs with a flax or chia seed egg, use plant-based milk, and vegan butter. Ensure your bread is vegan-friendly too.
  • Gluten-Free: Opt for gluten-free bread and check that all ingredients are gluten-free if you have dietary restrictions.

Easy Overnight French Toast Casserole


  • 1 loaf of French bread (about 16 ounces)
  • 8 large eggs
  • 2 cups of milk
  • 1/2 cup of heavy cream
  • 1/2 cup of granulated sugar
  • 1 tablespoon of vanilla extract
  • 1/2 teaspoon of ground cinnamon
  • 1/4 teaspoon of ground nutmeg
  • 1/4 teaspoon of salt
  • 1/2 cup of unsalted butter (1 stick), melted
  • 1/2 cup of brown sugar
  • Optional toppings: maple syrup, fresh berries, powdered sugar


  • Slice the French bread into 1-inch thick slices and arrange them in a greased 9×13-inch baking dish.
  • In a large bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined.
  • Pour the egg mixture evenly over the bread slices. Make sure all the bread is soaked in the mixture. You can press down on the bread gently with a fork to ensure it absorbs the liquid.
  • Cover the baking dish with plastic wrap and refrigerate it overnight, or for at least 6 hours. This allows the bread to absorb all the flavors.
  • In the morning, preheat your oven to 350°F (175°C).
  • In a separate bowl, mix the melted butter and brown sugar until you have a smooth mixture. Pour this evenly over the bread.
  • Bake in the preheated oven for about 45-55 minutes, or until the top is golden brown and the center is set.
  • Remove from the oven and let it cool for a few minutes before serving. You can drizzle maple syrup over the top and add fresh berries or a dusting of powdered sugar for extra flavor.
