Ingredients You’ll Need

Each ingredient here plays a part in building that dreamy Blueberry Croissant French Toast Casserole Recipe. I recommend using fresh or day-old croissants since they soak up the custard beautifully without getting soggy. Also, whole milk and heavy cream make the custard rich and velvety, so don’t skip those if you want that perfect texture.

• Croissants: Day-old ones work great—they hold their shape better and soak up custard perfectly without falling apart.
• Eggs: Provide structure and richness; always use fresh eggs for the best custard.
• Whole milk: Warmed to help the custard mix smoothly and soak into the bread.
• Heavy cream: Adds luxurious creaminess to the custard.
• Melted butter: Gives that buttery depth in the custard and keeps it rich.
• Sugar: Just enough to sweeten the custard without overpowering the fresh blueberries.
• Vanilla extract: The secret flavor enhancer that brings warmth and aroma.
• Ground cinnamon: Adds a cozy spice that pairs beautifully with the blueberries.
• Fine sea salt: Balances the sweetness and intensifies all the flavors.
• Blueberries: Fresh or frozen; bursting with juice and freshness to wake up every bite.

Variations

I love how forgiving and versatile this Blueberry Croissant French Toast Casserole Recipe is — I’ve played around with it plenty and highly encourage you to personalize it to your taste and occasion! Whether you swap berries or swap croissants, this recipe is your canvas.

• Mixed Berries: I often substitute or add raspberries, strawberries, or blackberries for more color and a variety of tartness that keeps it fresh.
• Gluten-Free Version: Use gluten-free croissants (found at specialty stores) and it still turns out just as indulgent.
• Nutty Twist: Sprinkle chopped toasted almonds or pecans on top before baking for a delightful crunch.
• Spiced Up: For fall vibes, add a pinch of nutmeg or allspice to the custard mix.

How to Make Blueberry Croissant French Toast Casserole Recipe

Step 1: Prep Your Dish and Croissants

Start by preheating your oven to 350°F. Butter a 9”x13” casserole dish to keep the edges from sticking and add a subtle richness. While the oven is warming, cut your croissants into roughly 1 to 1.5-inch cubes—this size lets the croissant soak up plenty of custard while keeping some flaky texture. Arrange the cubes evenly in the casserole dish—don’t be shy about filling every corner!

Step 2: Whisk Up That Perfect Custard

In a bowl, whisk together 5 eggs with 1 cup of warmed whole milk, ½ cup heavy cream, 4 tablespoons melted butter, ⅓ cup sugar, 2 teaspoons vanilla, 2 teaspoons cinnamon, and ½ teaspoon fine sea salt. I love how the warm milk helps everything mix smoothly without any stubborn lumps. This custard will soak into the croissants, turning them tender and custardy.

Step 3: Build and Let It Soak

Pour the custard right over the croissant pieces, then gently press down with a spatula so the bread starts absorbing those flavorful liquids. Scatter 2 cups of blueberries on top and poke some between the croissant layers — this creates juicy pockets of sweetness inside every bite. Now, here’s the magic: let it sit for 15 minutes minimum, but if you have the time, cover it with foil and refrigerate overnight. I discovered this trick—it seriously makes the casserole taste even better and helps the custard fully soak in.

Step 4: Bake to Golden Heaven

Bake your casserole for about 45 minutes until it’s fully set and the top is beautifully golden brown. You’ll know it’s done when a knife inserted near the center comes out clean. The edges will be a bit crispy, contrasting with the soft custard center. Let it cool for a few minutes before serving, but honestly, if you’re like me, you’ll want to dig in right away!

How to Serve Blueberry Croissant French Toast Casserole Recipe

Garnishes

I love topping this casserole with an extra handful of fresh blueberries and a light dusting of powdered sugar—it just makes the whole thing look and taste irresistible. Maple syrup is a must in my book; I drizzle it generously over each serving for that sweet, sticky goodness that complements the berry tang. Sometimes, for a little pop of color and texture, I add sliced strawberries or a few mint leaves on top.

Side Dishes

This casserole is pretty hearty on its own, but if you want to round out the meal, I like pairing it with crispy bacon or turkey sausage for a salty balance. Fresh fruit salad on the side or a dollop of Greek yogurt can lighten things up as well. And for drinks? A strong cup of coffee or some freshly squeezed orange juice makes the combo feel like brunch perfection.

Creative Ways to Present

For special occasions, I’ve baked this casserole in individual ramekins—super cute for a brunch party and perfect for portion control! Another fun trick is layering the croissant and blueberry mixture in a clear glass baking dish or trifle bowl so you can see all those beautiful layers. You could even sprinkle on some toasted almonds or edible flowers as a fancy garnish to wow your guests.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftovers (and you usually will unless you’re feeding a crowd), store them in an airtight container in the fridge. I like to portion them into individual servings with plastic wrap or foil so I can grab breakfast on the go. They’ll keep well for up to 3 days.

Freezing

I’ve frozen this casserole successfully! After baking and cooling completely, I cut it into portions and freeze them in airtight containers or freezer bags. When you want to enjoy it, thaw overnight in the fridge and reheat gently. The texture stays great, and it’s a lifesaver for busy mornings.

Reheating

To reheat leftovers, I pop individual portions into a 350°F oven for about 15 minutes or until warmed through and crisped up again. You can also microwave them covered for about 1-2 minutes, but the oven method preserves that lovely contrasting texture best.
