Overhead view of all of the raw ingredients needed to make French toast casserole on a clean countertop.
  • Bread: French bread, challah, or French country bread are ideal for their ability to absorb the custard without becoming too soggy.
  • Milk: Whole milk provides creaminess, but 2% milk can be used for a lighter version. For a dairy-free alternative, your favorite plant-based milk can be used.
  • Eggs: Essential for the custard base, providing structure and richness. For an egg white only version, substitute 2 egg whites for every 1 egg called for in the recipe. For a plant-based substitute, use a commercial egg replacer or flax egg.
  • Brown Sugar: Adds sweetness and a hint of molasses flavor. If unavailable, granulated sugar can be used.
  • Vanilla Extract & Spices: Vanilla, cinnamon, and nutmeg are key for flavor. Feel free to adjust the amounts to your liking.
  • Heavy Cream: Adds richness; half-and-half can be used as a lighter alternative.
  • Berries: Optional but add a fresh, tart contrast to the sweetness. Use any berries you like or omit them entirely.

Flavor Options

To keep your mornings interesting, try these flavor variations:

  • Apple Cinnamon: Add diced apples and extra cinnamon for a fall-inspired twist.
  • Chocolate Chip: Sprinkle in some chocolate chips for a sweet surprise that kids will adore.
  • Berry Medley: Mix in a variety of berries like strawberries, blueberries, and raspberries for a burst of freshness.
  • Pumpkin Spice: In the fall, add pumpkin puree and pumpkin spice to the custard mixture for a seasonal treat.
  • Coffee Creamer: For a unique and flavorful twist, replace the milk, cream, sugar, and spices with 2 1/2 cups of your favorite flavored coffee creamer. Whisk the creamer with the 8 eggs called for in the recipe and pour over the cubed bread. This variation infuses the casserole with the subtle flavors and sweetness of the creamer, adding a delightful new dimension to the dish.

Toppings

A French toast casserole is delightful on its own, but the right toppings can elevate it to new heights of deliciousness. Whether you’re looking for extra sweetness, a touch of freshness, or a bit of crunch, there’s a plethora of options to choose from. Here are some topping ideas to make your casserole truly special:

  • Syrups and Sauces: Traditional maple syrup is always a winner, but don’t hesitate to try other flavors like blueberry, strawberry, or Cinnamon Buttermilk Syrup. A drizzle of chocolate sauce or a dollop of fruit compote can also add a delightful twist.
  • Fresh Fruit: Nothing beats the freshness of seasonal fruits. Berries, sliced bananas, diced apples, or peaches offer a refreshing contrast to the rich casserole. In the summer, try tropical fruits like mango or pineapple for a unique twist.
  • Whipped Cream or Yogurt: A dollop of whipped cream adds a luxurious touch, while a spoonful of Greek yogurt can provide a tangy contrast and make the dish a bit lighter.
  • Sweet Spreads: Nutella, peanut butter, or any nut or seed butter can add a creamy, rich element. These are particularly popular with kids and can make the casserole more filling.
  • Spices and Herbs: A light dusting of cinnamon, nutmeg, or powdered sugar can enhance the flavors beautifully. For a hint of freshness, consider a sprinkle of finely chopped mint or basil.
  • Crunchy Elements: Chopped nuts, granola, toasted coconut flakes, or a crumble topping made from brown sugar and butter can add an irresistible crunch and depth of flavor.

Troubleshooting

  • Soggy Casserole: Ensure the bread is adequately cubed and the egg mixture is evenly distributed. Avoid over-soaking the bread.
  • Dry Casserole: Cover with foil if the top is browning too quickly. Make sure not to overbake.
  • Not Sweet Enough: Adjust the amount of sugar in the custard or topping, or serve with additional maple syrup.

Tips From the Chef

  • Use stale bread in your casserole. It absorbs the egg mixture without falling apart.
  • Whisk the egg mixture thoroughly to avoid lumps.
  • Let the casserole sit for a few minutes after baking for it to set properly.
