Ingredients You’ll Need

What’s magical about the Blueberry French Toast Casserole is how a handful of straightforward ingredients combine for maximum flavor and texture. Each one adds its own special touch, from the bread’s heartiness to the sweet pop of blueberries. Here’s what you’ll need, along with why it matters:

French bread: The sturdy texture absorbs the custard beautifully without getting soggy—ideal for casserole perfection.
Blueberries: Fresh or frozen, each berry adds a tangy-sweet pop and gorgeous color.
Eggs: They’re the backbone of the custard, binding everything together for creamy richness.
Milk: Provides moisture and helps melt everything into that classic French toast flavor.
Heavy cream: Adds extra indulgence and a silky, melt-in-your-mouth bite.
Maple syrup or honey: Sweetens the custard and deepens the brunchy flavor profile.
Vanilla extract: Brings a hint of warmth and rounds out the flavors.
Ground cinnamon: Just the right amount of spice for cozy notes.
Salt: Balances the sweetness and enhances every other ingredient.
Butter: A touch of melted butter keeps everything moist and golden.
Topping (optional): For extra crunch and decadence, combine flour, brown sugar, cinnamon, and cold butter—crumbled over the top for the perfect finish.

How to Make Blueberry French Toast Casserole

Step 1: Prep Your Baking Dish and Layer the Goodies

Start by greasing a 9×13-inch baking dish so nothing sticks. Scatter half of your bread cubes across the bottom, then sprinkle half of the blueberries evenly over the bread. Repeat with the remaining bread and blueberries, creating irresistible pockets of berry goodness in every slice.

Step 2: Whisk Up the Custard

In a large bowl, whisk together the eggs, milk, heavy cream, maple syrup (or honey), vanilla, cinnamon, and salt. The key is to whisk until it’s smooth and everything is beautifully combined—this custard bath is what transforms dry bread into luscious French toast casserole magic.

Step 3: Soak It and Chill

Pour the custard mixture evenly over all the bread and blueberries. Gently press down so every cube gets saturated. Cover the dish tightly with plastic wrap and let it sit in the fridge. Overnight gives the richest flavor, but even four hours will do if you’re short on time.

Step 4: Mix Up the Crumb Topping (Optional)

If you want to add a sweet, crunchy topping, combine flour, brown sugar, and cinnamon in a small bowl. Cut in the cold butter pieces with a fork or your fingers until it clumps into small crumbs. Keep this in the fridge until you’re ready to bake.

Step 5: Bake to Perfection

When you’re ready to bake, preheat your oven to 350°F (175°C). Sprinkle the crumb topping evenly over the soaked bread and drizzle with melted butter. Bake uncovered for 45 to 50 minutes until the top is golden and set. Let the casserole cool for about 10 minutes before diving in for those perfect, custardy slices.

How to Serve Blueberry French Toast Casserole

Garnishes

Finish your Blueberry French Toast Casserole with a dusting of powdered sugar, a drizzle of warm maple syrup, or extra fresh blueberries on top. These little extras make every serving feel special and look brunch-worthy for any occasion.

Side Dishes

This casserole pairs perfectly with crispy bacon, savory sausage links, or a fresh fruit salad. If you want to keep things simple, serve with a dollop of vanilla yogurt or lightly whipped cream for a cool, creamy touch.

Creative Ways to Present

For gatherings, slice and serve your Blueberry French Toast Casserole in neat squares on a platter, or scoop out heaping spoonfuls straight from the baking dish for a rustic vibe. Individual ramekins work beautifully for a personalized touch, and a sprinkle of granola or chopped nuts can bring extra flair and crunch.

Make Ahead and Storage

Storing Leftovers

Leftover Blueberry French Toast Casserole can be a real breakfast gift all week long! Allow the casserole to cool to room temperature, then cover tightly or transfer slices to an airtight container. Store in the refrigerator for up to three days—the flavors just get better as they meld together.

Freezing

This casserole is freezer-friendly! Wrap individual slices or the whole (cooled) casserole tightly in plastic wrap and then foil. Freeze for up to two months. Thaw overnight in the refrigerator before reheating so it keeps its creamy, tender texture.

Reheating

Reheat slices in the microwave for quick convenience, or warm your whole casserole in a 350°F oven, covered with foil, for about 20 minutes or until heated through. If you want the topping extra crispy, remove the foil for the last few minutes.

FAQs

Can I make Blueberry French Toast Casserole with dairy-free ingredients?

Absolutely! Substitute almond milk for regular milk and coconut cream for the heavy cream. Use plant-based butter (or omit the topping), and your casserole will still come out creamy, flavorful, and perfect for dairy-sensitive guests.

Should I use fresh or frozen blueberries?

You can use either! Frozen blueberries are especially handy out of season and don’t even need to be thawed. Fresh blueberries give extra pop and color, but both will burst deliciously during baking.

Can I assemble the casserole the same day I bake it?

You can let your Blueberry French Toast Casserole chill for as little as four hours in the fridge, although overnight is ideal for the bread to soak up the custard for maximum flavor and creaminess.

Is it possible to halve the recipe?

Yes! If you’re cooking for a smaller group, simply prepare the ingredients as written but split everything in half. Use an 8×8-inch baking dish and reduce baking time by about 10 minutes, watching closely until the casserole is golden and set.

What other toppings can I add instead of the crumb topping?

Feel free to add chopped pecans or walnuts for crunch, sprinkle on toasted coconut, or even swirl a bit of cream cheese into the custard before baking for a cheesecake twist. This dish is endlessly customizable!
