Ingredients You’ll Need
Here’s everything you’ll need to make this overnight French toast casserole:
For the Casserole:
- 1 loaf of French bread or thick Texas toast
- 8 large eggs
- 2 cups half-and-half
- 1/2 cup milk
- 3 tablespoons granulated sugar
- 1 1/2 teaspoons pure vanilla extract
- 1/2 teaspoon ground cinnamon
- 1/2 teaspoon ground nutmeg
- 1/2 teaspoon salt
For the Cinnamon Crunch Topping:
- 1 1/2 sticks (3/4 cup) butter, softened
- 1 cup light brown sugar, packed
- 1 tablespoon light corn syrup (optional, for extra stickiness)
- 1 teaspoon ground cinnamon
- 1/2 teaspoon ground nutmeg
Kitchen Equipment Needed
- 9”x13” baking dish
- Mixing bowls (large and medium)
- Whisk
- Measuring cups and spoons
- Butter knife or spatula
- Foil for overnight refrigeration
Step-by-Step Instructions
Prepare the Casserole:
- Prep the Baking Dish: Coat a 9”x13” baking dish with butter or cooking spray to prevent sticking. Set it aside.
- Slice the Bread: Cut your French bread or Texas toast into 1-inch-thick slices. Arrange the slices in rows in the prepared baking dish, overlapping them slightly.
- Make the Custard: In a large bowl, whisk together the eggs, half-and-half, milk, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined.
- Pour Over Bread: Slowly pour the custard mixture over the bread slices, ensuring every piece is thoroughly coated. Use a spoon to spread the mixture between slices if needed. Cover the dish with foil and refrigerate overnight.
Bake the Casserole:
- Preheat the Oven: The next morning, preheat your oven to 350°F.
- Flip the Bread: Carefully flip each slice of bread to ensure it’s fully soaked in the custard. This step ensures even distribution of flavor and texture.
Make the Cinnamon Crunch Topping:
- In a medium bowl, mix together the softened butter, brown sugar, light corn syrup (if using), cinnamon, and nutmeg until smooth.
- Spread the topping evenly over the bread slices. For extra flavor, you can also spread some topping between the slices.
Bake:
Bake the casserole for 35-40 minutes, or until it’s puffed and golden. The topping should be slightly crispy, while the bread remains soft and custardy.
Tips and Variations
- Bread Options: While French bread and Texas toast work wonderfully, you can also use challah, brioche, or even cinnamon raisin bread for extra flavor.
- Add-ins: Sprinkle in fresh fruit like berries or diced apples before baking, or mix in chopped nuts like pecans or walnuts for added crunch.
- Dairy-Free Option: Substitute the half-and-half and milk with almond milk, oat milk, or any other non-dairy alternative. Use vegan butter for the topping.
- Spices: Feel free to adjust the cinnamon and nutmeg to taste, or add a pinch of ground ginger or cardamom for a unique twist.
How to Store and Reheat Leftovers
If you’re lucky enough to have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To reheat, place a slice in the oven at 325°F for 10-15 minutes or microwave it for 30-60 seconds until warmed through. The topping may lose some of its crispness, but the flavors will remain just as delicious.
Food and Drink Pairings
This casserole pairs beautifully with a fresh fruit salad, crispy bacon, or breakfast sausage. For beverages, serve with hot coffee, tea, or a refreshing mimosa for a festive touch.
FAQs
Can I Make This Recipe Gluten-Free?
Yes! Simply use your favorite gluten-free bread. Ensure that all other ingredients, like vanilla extract and spices, are gluten-free as well.
