Why You’ll Love Berry French Toast Casserole Recipe

I appreciate how easy this recipe is to prepare, especially on busy mornings or holidays. I like that I can assemble everything the night before and wake up knowing breakfast is already handled. I also love the balance of textures, from the tender soaked bread to the crisp, sweet topping and the bursts of fresh fruit throughout.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

Casserole
1 lb loaf Sourdough Or French Bread
1 ½ cups (195g) blueberries
1 lb strawberries, washed, hulled and chopped*
8 large eggs
2 cups (480ml) milk (whole or 2%)
1/2 cup (120ml) heavy whipping cream
1/2 cup (104g) granulated sugar
1/4 cup (36g) packed light brown sugar
2 tbsp vanilla extract
1 1/2 tsp ground cinnamon

Topping
3/4 cup (98g) all-purpose flour
3/4 cup (169g) packed light brown sugar
2 tsp cinnamon
1/4 tsp salt
1/2 cup (112g) butter, cut into pieces

Directions

I start by greasing a 9 x 13 casserole dish and setting it aside. I cut the bread into 1-inch chunks, then combine the bread and fruit and spread them evenly in the dish. In a large bowl, I whisk together the eggs, milk, cream, both sugars, vanilla, and cinnamon until smooth. I pour this mixture evenly over the bread, making sure everything gets well soaked.

I cover the casserole and store it in the fridge for several hours or overnight. When I’m ready to bake, I preheat the oven to 350 degrees F. For the streusel topping, I combine the flour, brown sugar, cinnamon, and salt, then cut in the butter until the mixture forms a crumble. I sprinkle the topping evenly over the casserole and bake it for 45 minutes to 1 hour, depending on how soft or firm I want the final texture. I serve it warm with syrup and optional toppings like powdered sugar or extra fruit.

Servings and Timing

I usually get about 10–12 servings from this casserole. Prep time takes around 20 minutes, and baking time is about 45 minutes, making the total time approximately 1 hour and 5 minutes.

Variations

I sometimes switch up the berries by using raspberries or blackberries instead of blueberries. I also like adding a little orange zest to the custard for a bright citrus note. For extra crunch, I occasionally mix chopped nuts into the streusel topping.

Storage/Reheating

I store leftovers covered in the refrigerator for up to 3 days. To reheat, I warm individual portions in the microwave or place the casserole in the oven at 325 degrees F until heated through. I find it stays moist and flavorful even after reheating.

FAQs

Can I make this casserole ahead of time?

Yes, I often prepare it the night before and let it soak in the fridge overnight.

What kind of bread works best?

I prefer sourdough or French bread because they hold up well and absorb the custard nicely.

Can I use frozen berries?

I can, but I usually thaw and drain them first to avoid excess liquid.

How do I know when it’s done baking?

I check the center with a knife and look for fruity juices rather than milky custard.

Can I make this dairy-free?

I can substitute dairy-free milk and butter alternatives with good results.

Is the streusel topping necessary?

I love the topping, but the casserole still tastes great without it.

Can I reduce the sugar?

I sometimes cut back slightly on the sugar without affecting the texture.

What toppings go well with this casserole?

I like maple syrup, powdered sugar, or extra fresh fruit on top.

Can I freeze leftovers?

I can freeze individual portions, though the texture is best when fresh.
