It quickly became one of those recipes we turn to whenever we want a breakfast that feels a little extra special without a lot of extra work.

Ingredients You’ll Need
For the Casserole:
- 1 loaf brioche or challah bread, cut into cubes (about 8 cups)
- 5 large eggs
- 1 1/2 cups whole milk
- 1/2 cup heavy cream
- 1/3 cup granulated sugar
- 2 tablespoons brown sugar

Pro Tips
Use a mix of fresh berries for the best flavor and texture. Combining different berries adds depth and balance.
If using frozen berries, thaw and drain them first to avoid excess moisture. This helps prevent the casserole from becoming too watery.
Use slightly stale bread for the best results. It absorbs the custard better and maintains its structure.
Whisk the custard thoroughly to ensure even flavor throughout the dish. This helps distribute the sweetness and spices.
Layer the berries evenly throughout the casserole. This ensures every bite has a good balance of fruit and bread.
Let the casserole rest for a few minutes after baking. This helps it set and makes it easier to serve.
Tools You’ll Need
- Large mixing bowl
- Whisk
- 9×13-inch baking dish
- Measuring cups and spoons
- Knife and cutting board
- Spatula
Substitutions and Variations
If you don’t have brioche or challah, you can use French bread or another sturdy loaf. Slightly dried bread works best for soaking up the custard.
You can use frozen berries if fresh are not available. Just make sure to thaw and drain them before adding.
For a lighter version, you can reduce the cream and use more milk instead. This will slightly change the richness but still taste great.
You can add a hint of lemon zest to brighten the flavor. It pairs beautifully with the berries.
For a dairy-free option, use plant-based milk and a dairy-free cream alternative. The dish will still be delicious and satisfying.
Make Ahead Tips
Mixed berry French toast casserole is ideal for preparing ahead, making your mornings feel easy and relaxed. After assembling the casserole, cover it tightly with plastic wrap or foil and place it in the refrigerator overnight. This allows the bread to fully absorb the custard and helps the berry flavors blend into the dish.
If you’re using fresh berries, you can wash and prep them ahead of time. Store them in the refrigerator until you’re ready to assemble. This helps streamline the process and keeps everything fresh.
You can also bake the casserole ahead of time and reheat it before serving. While it’s best fresh, reheating works well when done properly. This makes it a convenient option for gatherings or busy mornings.
Instructions
Step 1: Prepare the Baking Dish
Lightly grease a 9×13-inch baking dish with butter or cooking spray. This helps prevent sticking and makes serving easier. Set aside.
Step 2: Layer the Bread and Berries
Place half of the cubed bread into the baking dish. Add half of the mixed berries evenly over the bread. Repeat with the remaining bread and berries to create even layers.
Step 3: Make the Custard
In a large mixing bowl, whisk together the eggs, milk, heavy cream, granulated sugar, brown sugar, vanilla extract, cinnamon, and salt. Continue whisking until the mixture is smooth and fully combined. This creates a rich custard base.
Step 4: Combine and Chill
Pour the custard evenly over the layered bread and berries. Gently press the bread down with a spoon or spatula to ensure all pieces are coated. Cover and refrigerate overnight.
Step 5: Preheat the Oven
When ready to bake, remove the casserole from the refrigerator and let it sit at room temperature for about 20 minutes. Preheat your oven to 350°F. This helps ensure even baking.
Step 6: Add the Topping
If using the optional topping, mix the brown sugar, cinnamon, and melted butter in a small bowl. Sprinkle it evenly over the casserole. This creates a slightly crisp and caramelized finish.
Step 7: Bake the Casserole
Place the dish in the preheated oven and bake for 40–45 minutes. The top should be golden brown, and the center should be set but still soft. If needed, cover loosely with foil to prevent over-browning.
Step 8: Cool and Serve
Remove the casserole from the oven and let it cool for a few minutes before serving. This helps it set and makes it easier to slice. Serve warm for the best flavor.
Serving Suggestions
Mixed berry French toast casserole pairs beautifully with a dusting of powdered sugar. This adds a light sweetness and enhances the presentation. It’s a simple but effective finishing touch.
A drizzle of maple syrup or honey can add extra sweetness if desired. The syrup blends with the berry juices and custard for a rich and flavorful bite. A little goes a long way.
For a fresh contrast, serve with additional berries or a fruit salad. This enhances the natural flavors and adds brightness to the dish. It also makes the presentation more vibrant.
You can also serve it with whipped cream or a spoonful of yogurt. This adds a creamy element that complements the soft texture. It’s perfect for brunch or special occasions.
Leftovers and Storage
Allow any leftover casserole to cool completely before storing. Cover the dish tightly or transfer portions to an airtight container. Store in the refrigerator for up to three days.
To reheat, place portions in a 300°F oven until warmed through. This helps maintain the texture and prevents the casserole from becoming too soft. You can also reheat individual portions in a skillet.
For longer storage, the casserole can be frozen. Cut it into portions and place them in a freezer-safe container. It can be stored for up to two months.
When ready to eat, thaw overnight in the refrigerator and reheat in the oven. This helps preserve both flavor and texture. Avoid microwaving if possible.
