Ingredients and Equipment
To create this scrumptious casserole, you'll need the following ingredients and equipment:

- 1 loaf of day-old bread (such as brioche, challah, or Texas toast)
- 8 large eggs
- 2 cups of milk (whole or 2%)
- 1 cup of heavy cream
- 1/2 cup of granulated sugar
- 1 teaspoon of vanilla extract
- 1 teaspoon of ground cinnamon
- 1/2 teaspoon of salt
- Optional mix-ins: fresh berries, sliced bananas, chocolate chips, nuts, or dried fruits
- Cooking spray or butter for greasing
- 9x13-inch baking dish
- Large mixing bowl
- Whisk
Choosing the Right Bread
Using day-old bread is crucial for achieving the perfect texture in your French Toast Breakfast Casserole. Stale bread absorbs the custard mixture better than fresh bread, resulting in a creamy interior and crispy edges. Brioche, challah, or Texas toast are excellent choices due to their rich, tender crumb and ability to hold their structure when soaked in liquid.
Preparation and Assembly
To prepare the French Toast Breakfast Casserole, follow these simple steps:
- Grease a 9x13-inch baking dish with cooking spray or butter.
- Tear the bread into 1-inch pieces and evenly distribute them in the prepared baking dish.
- In a large mixing bowl, whisk together eggs, milk, heavy cream, sugar, vanilla extract, cinnamon, and salt until well combined.
- Pour the custard mixture evenly over the bread pieces, ensuring they are all well-coated. Gently press down on the bread to help it absorb the custard.
- Cover the baking dish with plastic wrap and refrigerate for at least 2 hours, or up to overnight. This allows the bread to soak up the custard and ensures a creamy interior.
- Preheat your oven to 375°F (190°C).
- If using any optional mix-ins, gently fold them into the casserole at this point.
- Bake the casserole for 45-55 minutes, or until the top is golden brown, and the edges are lightly puffed.
- Let the casserole rest for 10-15 minutes before serving to allow it to set slightly.
Mix-In Ideas and Variations
One of the best things about French Toast Breakfast Casserole is its versatility. You can customize it with various mix-ins and variations to suit your taste preferences. Here are some ideas to inspire you:

| Mix-In | Description |
|---|---|
| Fresh berries | Stir in 1-2 cups of fresh berries, such as blueberries, raspberries, or sliced strawberries, for a fruity twist. |
| Bananas and nuts | Combine sliced bananas and chopped nuts, like pecans or walnuts, for a classic breakfast flavor combination. |
| Chocolate chips | Add 1-2 cups of semi-sweet or dark chocolate chips for a decadent, indulgent treat. |
| Dried fruits | Mix in 1 cup of dried fruits, such as raisins, cranberries, or chopped apricots, for a chewy, sweet contrast. |
| Savory options | For a savory twist, try adding cooked bacon, sausage, or spinach, and using shredded cheese as a topping. |
Make-Ahead Tips
French Toast Breakfast Casserole is an excellent make-ahead dish, perfect for busy mornings or entertaining. Here are some tips for preparing it in advance:
- Assemble the casserole up to 24 hours ahead, cover it tightly with plastic wrap, and refrigerate.
- To save even more time, you can also bake the casserole ahead of time. Let it cool completely, then cover it with foil, and refrigerate. Reheat in a 300°F (150°C) oven for 20-25 minutes, or until warmed through.
- If you prefer to bake the casserole fresh in the morning, you can still prepare the custard mixture and soak the bread the night before. Cover both the custard and the bread separately, and refrigerate until ready to use.
