Gathering the right ingredients is key to creating that dreamy texture and vibrant flavor this dish is famous for. Each simple component plays a crucial role, from the rustic bread that provides the perfect chewiness to the blueberries that bring a punch of freshness and color.

Rustic bread (1 pound, cut into 1-inch cubes): Using a sturdy loaf ensures the bread soaks up the custard without turning mushy.
Blueberries (1 1/2 to 2 cups, fresh or frozen): These add natural sweetness and a beautiful jewel-like pop throughout the casserole.
Large eggs (5): Eggs are essential for the custard base that binds the dish together and gives it that rich, creamy texture.
Milk (2 cups, whole or 2%): Milk balances the richness, creating the perfect custard consistency.
Heavy cream (1 cup): Adds a decadent creaminess that makes each bite silky and indulgent.
Vanilla extract (1/2 teaspoon): Brings subtle warmth and enhances the sweetness naturally.
Sugar (8 tablespoons, divided): Sweetens the custard and creates a delightful crust when sprinkled on top.
Lemon zest (1 tablespoon, finely grated): A zing of citrus cuts through the richness and brightens the flavor.
Kosher salt (1/8 teaspoon): Enhances all the sweet and savory notes perfectly.
Unsalted butter (2 tablespoons, diced): Dots of butter melt into the casserole’s top for a golden, luscious finish.

How to Make Baked Blueberry French Toast Casserole Recipe

Step 1: Prepare the Bread and Blueberries

Start by buttering a 9 x 13-inch baking dish to prevent sticking and add flavor. Lay half of the rustic bread cubes evenly in the dish, then sprinkle two-thirds of the blueberries on top. Layer the remaining bread cubes and finish with the remaining blueberries. If you’re using frozen blueberries, keep them frozen; this helps them retain their color and prevents the casserole from turning purple in spots.

Step 2: Whisk Together the Custard Mixture

In a large bowl, beat together the eggs, milk, heavy cream, vanilla extract, 6 tablespoons of sugar, lemon zest, and kosher salt until everything is smooth and well combined. This custard will soak into the bread, bringing softness without losing structure.

Step 3: Combine and Soak

Pour the custard evenly over the layered bread and blueberry mixture. Gently press down with your hands or a spatula, being careful not to burst the berries, ensuring the custard soaks into every nook and cranny. Cover and let it soak for at least 30 minutes, or for even better flavor, refrigerate overnight for a deep, custardy treat.

Step 4: Bake to Perfection

Preheat your oven to 350°F about 15 minutes before baking. If your casserole was refrigerated overnight, allow it to come closer to room temperature as the oven heats. Just before putting it in the oven, sprinkle the top with the remaining 2 tablespoons of sugar and scatter the diced butter evenly across. Bake for 45 minutes, or until the casserole puffs up slightly and turns a gorgeous golden brown. If chilled overnight, it may need a few extra minutes to cook through.

Step 5: Let It Rest Before Serving

Once out of the oven, allow the casserole to cool for about 10 minutes. This resting period helps the custard set and makes slicing easier. Serve it warm, either dusted with powdered sugar or drizzled with maple syrup for an extra special morning treat.

The pudding has three visible layers: a golden-brown crusty top with blueberries scattered throughout, a light yellow custard middle with soft bread pieces soaked in it, and a slightly darker purple layer from the blueberries swirling inside the custard at the bottom and sides.

Garnishes

Brighten up your dish with a light dusting of powdered sugar to add sweetness and a pretty finish. Fresh mint leaves, a dollop of whipped cream, or a drizzle of pure maple syrup are fantastic options that complement the blueberries beautifully and add an inviting touch.

Side Dishes

This casserole shines on its own but pairs wonderfully with a simple green salad to balance the richness or a side of crispy bacon or sausage for those who love a savory twist at breakfast. Fresh fruit salad is also an excellent companion to keep things light and refreshing.

Creative Ways to Present

For a festive brunch, serve your Baked Blueberry French Toast Casserole Recipe in individual ramekins for a charming personal touch. Alternatively, layer cubes of the casserole on a platter with extra fresh blueberries scattered around for a rustic yet elegant display. Adding edible flowers can also turn it into a stunning centerpiece for special occasions.

Make Ahead and Storage

Storing Leftovers

Leftover casserole keeps beautifully in the refrigerator for up to one week. Simply cover the dish tightly with plastic wrap or transfer to an airtight container to maintain its moisture and flavor.

Freezing

You can freeze the casserole before baking by assembling it in a freezer-safe dish, covering tightly, and freezing for up to one month. When ready, thaw overnight in the refrigerator and bake as usual. For baked leftovers, cool completely, then freeze in airtight containers for up to two months.

Reheating

To reheat, microwave individual portions for about 1 to 2 minutes until warm throughout, or bake the whole casserole at 350°F for 15 to 20 minutes until heated through and the top regains a bit of crispiness. Just be careful not to overheat to keep that custardy texture intact.

FAQs

Can I use bread other than rustic loaf for this casserole?

Yes! While a rustic bread is preferred for its firm texture, you can also use challah, brioche, or even a hearty sourdough. Just make sure it’s sturdy enough to absorb the custard without falling apart.

Do I have to soak the casserole overnight?

Overnight soaking is optional but highly recommended for maximum flavor and custard absorption. If you’re short on time, a 30-minute soak works, but longer soaking makes the bread irresistibly tender.

Can I substitute the blueberries with other fruits?

Absolutely! Raspberries, blackberries, or sliced strawberries work wonderfully and add their own unique flavor and color to the dish.

Is it necessary to use heavy cream?

Heavy cream adds richness and a silky texture, but you can substitute with all milk for a lighter casserole. Just expect a slightly less creamy result.

How do I prevent the casserole from turning soggy?

Using a sturdy, slightly stale bread helps soak up the custard without becoming mushy. Also, soaking the casserole uncovered during baking helps to evaporate excess moisture and keeps the crust golden and crisp.
