Why this recipe works
This French Toast Casserole works beautifully because it allows all the flavors to meld overnight. As the bread soaks in the egg mixture, it absorbs the rich flavors of milk, vanilla, cinnamon, and sugar, leading to a custardy texture that is dreamy when baked.
The combination of strawberries and blueberries not only adds fruity freshness but also enhances the color and visual appeal of the dish. My previous attempts at traditional French toast have sometimes resulted in uneven cooking. Batching it into a casserole ensures a consistent, perfectly set dish.

Additionally, the make-ahead aspect is a game-changer. Preparing the casserole the night before means that come morning, all you need to do is pop it in the oven and let it bake while you enjoy your first cup of coffee. This ease makes it an excellent choice for busy weekdays or special weekend brunches when extra time is at a premium.
Ingredients
- 1 loaf of bread (such as challah or brioche)
- 6 large eggs
- 2 cups milk (whole, 2%, or non-dairy alternatives like almond milk)
- 1/2 cup granulated sugar (or coconut sugar for a less refined option)
- 1 teaspoon vanilla extract
- 1 teaspoon ground cinnamon (substitute with nutmeg for a different flavor)
- 1/4 teaspoon salt
- 1 cup strawberries (sliced; blueberries can also be substituted with raspberries)
- 1 cup blueberries (can use blackberries as an alternative)
- Maple syrup (for serving)
Step-by-step instructions
Prep
- Grease a baking dish with butter or cooking spray.
- Cut the bread into cubes and place them evenly in the greased dish.
Cooking
- In a large bowl, whisk together the eggs, milk, sugar, vanilla extract, cinnamon, and salt until fully combined.
- Pour the egg mixture over the bread cubes, pressing down slightly to ensure the bread absorbs the liquid.
- Add the sliced strawberries and blueberries on top of the bread mixture.
Finishing
- Cover the baking dish with plastic wrap and refrigerate overnight to let the flavors meld.
- Preheat the oven to 350°F (175°C) and bake for 35-40 minutes, or until the casserole is golden brown and set in the middle.
- Serve warm, topped generously with maple syrup.
Chef’s tips for perfect results
- Maintain a consistent soak: Ensure the bread pieces are fully saturated in the egg mixture for even texture. Press down gently to aid absorption.
- Choose the right bread: Using high-quality challah or brioche enhances both flavor and texture, yielding a richer result than standard sandwich bread.
- Monitor baking time: Keep an eye on the casserole towards the end of the baking process to avoid overcooking. It should be golden but not dry.
- Rest before serving: Allow the casserole to sit for about 5 minutes after baking. This helps it set and makes it easier to cut into servings.
Common mistakes to avoid
- Not using enough eggs: Using fewer than six eggs can lead to a lack of custard-like texture. Always stick to the amount recommended for best results.
- Skipping the overnight soak: For optimal flavor and texture, avoid the temptation to skip refrigerating the dish overnight. This crucial step allows the bread to absorb the flavors.
- Underbaking: Removing the casserole too soon can result in a soggy texture. Make sure it is set and golden before taking it out.
- Using stale bread: Stale bread is perfect for this dish because it absorbs the egg mixture better. Fresh bread can lead to an overly mushy outcome.
- Too much liquid: Be cautious with the amount of milk used. Excessive liquid can prevent the casserole from baking properly and may lead to a soggy center.
Variations and substitutions
- Berries: Feel free to swap the strawberries and blueberries with other fresh fruits like peaches, mangoes, or even chocolate chips for a sweeter option.
- Sugar alternatives: Coconut sugar or honey can work well in place of granulated sugar if you prefer less refined options.
- Non-dairy milk: Substituting regular milk with almond, oat, or soy milk will maintain the integrity of the dish while catering to dairy-free diets.
- Flavor variations: Experiment by incorporating different spices, such as cardamom or cloves, to vary the flavor profile.
Serving suggestions and pairings
- Serve the French Toast Casserole with sides of crispy turkey bacon or chicken ham for a balanced breakfast platter.
- Pair it with fresh fruit salads or yogurt for added texture and flavor.
- Consider serving alongside a stout cup of coffee or a refreshing glass of orange juice for a complete meal.
Storage and reheating
- Store leftover casserole in an airtight container in the refrigerator for up to 3 days.
- Reheat portions in the microwave for about 30-60 seconds, or reheat in the oven at 350°F (175°C) until warmed through (approximately 10-15 minutes).
