Ingredients You’ll Need
These ingredients come together so effortlessly, and each one plays a starring role in delivering the luscious texture and vibrant flavor that make this casserole a standout. From the rich creaminess of the custard base to the sweet-tart pop of blueberries, every component is essential.
- 8 slices thick-cut bread (brioche or challah): Choose slightly stale for the perfect custard absorption and soft interior.
- 1 1/2 cups fresh or frozen blueberries: Fresh for brightness, frozen if you want convenience—just don’t thaw them to keep the texture intact.
- 6 large eggs: The glue that sets the custard, providing richness and body.
- 1 1/2 cups milk: Adds creaminess and balances the custard’s flavor.
- 1/2 cup heavy cream: Elevates the custard texture to luxuriously smooth and silky.
- 1/3 cup granulated sugar: Sweetens gently without overpowering the natural blueberry tang.
- 1/4 cup brown sugar (packed): Brings a warm caramel note that deepens the flavor complexity.
- 2 teaspoons vanilla extract: Infuses the custard with its unmistakably sweet aroma and flavor.
- 1/2 teaspoon ground cinnamon: Adds a subtle hint of spice that pairs beautifully with the fruit and custard.
- Pinch of salt: Balances sweetness and enhances all the other flavors.
- 1/4 cup unsalted butter, melted: Drizzled on top for a golden, luscious finish.
- Powdered sugar for serving (optional): A delicate dusting for that picture-perfect brunch presentation.
How to Make Overnight Blueberry French Toast Casserole Recipe
Step 1: Prepare Your Baking Dish and Bread
Start by greasing a 9×13-inch baking dish with butter to keep your casserole from sticking and add flavor. Then, cube your thick-cut bread and spread it evenly inside the dish, setting the stage for those custard-soaked, fluffy bites. Sprinkle the fresh or frozen blueberries evenly over the bread cubes, so each slice gets a juicy punch.
Step 2: Whisk the Custard Mixture
In a large bowl, whisk together the eggs, milk, heavy cream, granulated and brown sugars, vanilla extract, ground cinnamon, and a pinch of salt until everything is smooth and combined. This custard mixture is the magic that transforms simple bread and berries into a melt-in-your-mouth breakfast delight.
Step 3: Combine and Refrigerate Overnight
Pour the custard evenly over the bread and blueberries, gently pressing down to make sure every cube soaks up the custard goodness. Cover the dish tightly with plastic wrap and refrigerate overnight. This slow soak gives the bread time to absorb all the flavors and moisture you want in every bite.
Step 4: Bake to Golden Perfection
The next morning, preheat your oven to 350°F. Drizzle the melted butter over the top of the casserole to encourage a beautiful golden crust. Bake uncovered for 45 to 50 minutes until the top is golden and the custard has set into a soft, custardy texture that’s irresistible. Let it cool for about 5 minutes before serving to let everything settle.
How to Serve Overnight Blueberry French Toast Casserole Recipe
Garnishes
A light dusting of powdered sugar adds a pretty, sweet touch that also enhances each bite. Fresh mint leaves or extra fresh blueberries scattered over the top bring bursts of color and freshness. For an indulgent finish, a drizzle of maple syrup or a dollop of whipped cream pairs beautifully without overwhelming the natural flavors.
Side Dishes
This casserole stands beautifully on its own, but if you want to round out your breakfast, consider crispy bacon or sausage on the side for contrast. Fresh fruit salad or a tangy yogurt parfait can brighten the meal, offering a refreshing counterpoint to the rich custard.
Creative Ways to Present
For a brunch with friends, cut the casserole into neat squares and serve on a rustic wooden board with bowls of extra fruit and syrup. Layer slices with whipped cream and berries for a parfait-style presentation, or serve it with a dusting of cinnamon sugar for that extra cozy, homemade touch.
Make Ahead and Storage
Storing Leftovers
Leftovers keep wonderfully in an airtight container in the refrigerator for up to 3 days. The flavors even deepen, and you can enjoy a quick breakfast or snack by simply reheating a portion or two.
Freezing
You can freeze the casserole either before baking (after soaking overnight) or after it’s baked. Wrap it tightly with plastic wrap and aluminum foil, then freeze for up to 2 months. Thaw overnight in the fridge before reheating to retain the best texture.
Reheating
Reheat single servings in the microwave for 1 to 2 minutes or until warmed through. For a crispier top, reheat larger portions in a preheated 350°F oven for about 15 minutes. This method revives that fresh-baked appeal.
FAQs
Can I use any type of bread for this casserole?
Yes, but thick-cut bread like brioche or challah works best because it absorbs custard well while maintaining structure. Slightly stale bread is ideal to avoid sogginess.
What if I only have frozen blueberries?
Frozen blueberries can be used directly from the freezer without thawing. Thawing first may release too much juice, making the casserole watery.
How long can I refrigerate the casserole before baking?
It’s best to refrigerate overnight, roughly 8 hours, but you can leave it up to 24 hours for convenience without sacrificing texture or flavor.
Can I prepare this casserole dairy-free or vegan?
This specific recipe relies on eggs and dairy for the custard, but you can experiment with plant-based milk and egg substitutes, adapting cook times and textures accordingly.
Is this recipe suitable for meal prepping?
Absolutely! It’s one of the best meal prep-friendly breakfasts since you prepare it ahead, then just bake fresh in the morning or reheat leftovers.
