Ingredients You’ll Need for Blueberry French Toast Casserole
Main Ingredients
-
1 loaf of day-old brioche, challah, or French bread (cut into cubes)
-
1 ½ cups fresh or frozen blueberries
-
6 large eggs
-
2 cups milk or half-and-half
-
½ cup cream cheese (optional for richness)
-
½ cup maple syrup or brown sugar
-
1 teaspoon vanilla extract
-
1 teaspoon ground cinnamon

How to Make Easy Blueberry French Toast Casserole – Step-by-Step
Step 1: Prepare the Bread
Cut your bread into bite-sized cubes, about 1 inch each. Arrange half of them in a greased 9×13-inch baking dish.
Step 2: Add the Blueberries
Sprinkle half of your blueberries evenly over the bread. Add the remaining bread cubes and top with the rest of the blueberries.
Step 3: Make the Custard
In a mixing bowl, whisk together the eggs, milk, vanilla, cinnamon, and maple syrup until smooth. Pour the custard mixture evenly over the bread, pressing down lightly so every piece gets soaked.
Step 4: Make the Crumb Topping
In a separate bowl, combine the flour, brown sugar, and cinnamon. Cut in the butter with a fork or your hands until the mixture looks crumbly. Sprinkle this over the top of the casserole for that perfect golden crust.
Step 5: Chill or Bake
-
For make-ahead: Cover and refrigerate overnight.
-
For same-day baking: Let it sit for at least 30 minutes so the bread absorbs the custard.
When ready, bake at 350°F (175°C) for about 40–45 minutes, or until the top is golden and the center is set.
Step 6: Serve and Enjoy
Once baked, let it rest for 5–10 minutes before serving. Top it with powdered sugar, maple syrup, or even a scoop of whipped cream for an extra indulgent touch.
Tips for the Best Blueberry French Toast Casserole
-
Choose the right bread: Brioche or challah gives you a soft, rich texture. Avoid thin sandwich bread — it gets too soggy.
-
Let it soak: If you have time, let the casserole rest before baking so the bread fully absorbs the custard.
-
Use frozen blueberries: No need to thaw — just toss them in with a tablespoon of flour to prevent them from bleeding color into the mixture.
-
Add texture: Sprinkle crushed pecans, almonds, or oats on top for an extra crunch.
-
Make it extra creamy: Add a few dollops of cream cheese between the layers of bread before baking.
Variations & Customizations
Lemon Blueberry Twist
Add a teaspoon of lemon zest or a squeeze of lemon juice to the custard for a bright, fresh flavor that pairs beautifully with the berries.
Mixed Berry Version
Replace some of the blueberries with raspberries or strawberries for a colorful and tangy variation.
Healthier Option
Use whole-grain bread, almond milk, and a touch of honey instead of sugar. You can also cut back on the topping for a lighter dish.
Cinnamon Roll Style
Add a swirl of cinnamon and sugar between the bread layers for a sweet, bakery-inspired twist.
What to Serve with Blueberry French Toast Casserole
-
Fresh fruit salad – adds color and freshness.
-
Greek yogurt or whipped cream – creamy and light.
-
Crispy sausage – a savory side to balance the sweetness.
-
Hot coffee or tea – because no cozy breakfast is complete without it.
Storing and Reheating Tips
-
Refrigerate: Store leftovers in an airtight container for up to 3 days.

Can I use frozen blueberries?

Brioche, challah, or French bread are ideal because they’re sturdy and absorb custard without falling apart.
