Ingredients You’ll Need

Gathering the essentials for Tasty Blueberry French Toast Casserole couldn’t be easier. Each ingredient is thoughtfully chosen to create just the right texture, flavor balance, and pop of color in every forkful—it’s amazing how simple staples come together to make something special.

Day-old bread (8 slices, brioche or challah): Using slightly stale bread ensures it soaks up the custard beautifully without turning soggy.
Fresh blueberries (2 cups): The star of the show, adding bursts of sweetness, color, and juiciness in every bite.
Large eggs (4): Eggs create that creamy, custard-like base that holds the casserole together.
Milk (1 1/2 cups): Adds moisture and richness; whole milk will yield the creamiest texture, but any variety works.
Maple syrup (1/4 cup): Brings gentle, caramel-like sweetness and depth to the custard mixture.
Vanilla extract (1 teaspoon): Lends warmth and a comforting aroma that elevates the overall flavor.
Ground cinnamon (1/2 teaspoon): Gives the casserole a cozy, slightly spiced note that pairs perfectly with blueberries.
Salt (1/4 teaspoon): Just a pinch heightens all the other flavors and balances the sweetness.
Butter, melted (2 tablespoons): Drizzling butter over the top adds golden color and a rich finish as the casserole bakes.
Powdered sugar (1 tablespoon, optional): For that final pretty touch and a little extra sweetness as a garnish.
Extra blueberries (optional): Sprinkle on top after baking for extra freshness and color.

How to Make Tasty Blueberry French Toast Casserole

Step 1: Prepare Your Pan and Preheat

First things first—preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish. A slick of butter or a spritz of nonstick spray will do the trick, ensuring every serving comes out effortlessly golden and intact.

Step 2: Layer the Bread and Blueberries

Take your day-old bread and arrange the slices in the dish, laying them out in a cozy, single layer. This is where the magic starts: scatter two cups of vibrant blueberries evenly over the bread, letting them nestle into the nooks and crannies. They’ll burst with flavor as the casserole bakes.

Step 3: Whisk the Custard

In a large mixing bowl, whisk together eggs, milk, maple syrup, vanilla extract, cinnamon, and salt until smooth and well-combined. This rich custard both sweetens and softens the bread layers while giving the Tasty Blueberry French Toast Casserole its signature creamy texture.

Step 4: Pour and Soak

Gently pour the egg mixture evenly over the bread and blueberries. Every morsel should get a good soaking, so use the back of a spoon to gently push the bread down into the mixture, ensuring that creamy custard seeps into every slice.

Step 5: Butter and Rest

Drizzle the two tablespoons of melted butter all over the top of the casserole. This step adds richness and ensures a beautiful golden crust. Cover with aluminum foil and let it sit for 15 to 20 minutes—this allows every bit of bread to fully absorb all those luscious flavors.

Step 6: Bake to Perfect Golden-ness

Place the covered casserole in your preheated oven and bake for 30 minutes. Then, remove the foil and let it bake for another 15 to 20 minutes. You’re looking for a deeply golden top, bubbling edges, and a center that’s just set—this means the Tasty Blueberry French Toast Casserole is perfectly done!

Step 7: Cool, Garnish, and Serve

Let the casserole cool slightly before serving. Finish your masterpiece with a dusting of powdered sugar and an extra sprinkle of fresh blueberries, if you like. Every slice is full of irresistible color and comforting warmth.

Side Dishes

This Tasty Blueberry French Toast Casserole shines alongside crisp bacon, savory breakfast sausage, or a platter of mixed fresh fruit. A side of creamy Greek yogurt or vanilla-infused ricotta is also a winning pairing. For drinks, freshly brewed coffee and a pitcher of orange juice round out the ultimate breakfast or brunch spread.

Make Ahead and Storage

Storing Leftovers

Leftover Tasty Blueberry French Toast Casserole stores beautifully! Simply cover the baking dish tightly with foil or plastic wrap, or transfer slices to an airtight container. Keep them in the fridge for up to 3 days. The flavors become even richer, making this casserole a fabulous next-day breakfast or snack.

Freezing

If you want to make your mornings ultra-convenient, this casserole also freezes well. After it cools completely, cut into individual squares and wrap tightly in plastic wrap before placing in a freezer bag or airtight container. Freeze for up to 2 months. When cravings hit, just grab-and-go—a true breakfast lifesaver!

Reheating

For the best texture, reheat slices in the oven at 325°F (about 10-15 minutes) until warmed through and slightly crisp on top. Microwaving also works for a speedy option; just pop a slice on a plate and heat in 30-second bursts. Either way, it’s just as delicious as day one!

FAQs

Can I use frozen blueberries instead of fresh?

Absolutely! If using frozen blueberries, there’s no need to thaw them first—just toss them in straight from the freezer. This ensures they don’t bleed too much color and keeps the Tasty Blueberry French Toast Casserole looking and tasting fantastic.

What’s the best type of bread for this casserole?

Brioche and challah are top choices for their slight sweetness and pillowy, rich crumb. French bread or even sturdy sandwich bread will work well too, especially if it’s a day or two old, so it can fully absorb the custard without falling apart.

Can I prepare the casserole ahead of time?

Yes! You can assemble the entire casserole (through the soaking and butter-drizzling step) the night before. Cover and refrigerate overnight. When ready to bake, let it come to room temperature for about 20 minutes, then bake as directed. The overnight soak makes it even more lush and flavorful!

Is it possible to make a dairy-free version?

Definitely! Simply swap the milk for your favorite non-dairy milk (like almond, coconut, or oat milk) and use a plant-based butter. The Tasty Blueberry French Toast Casserole will still be delicious and creamy, perfect for dairy-free guests.

Can I double the recipe for a crowd?

You sure can! Just use a larger baking dish or make two casseroles side by side. Make sure to increase your baking time a bit and check that the center is set before removing from the oven. It’s a guaranteed crowd-pleaser at any brunch table!

With its cheerful bursts of blueberry, tender golden bread, and comforting custard, Tasty Blueberry French Toast Casserole is a crowd-pleasing recipe worth adding to your breakfast repertoire.
