Ingredients You’ll Need

The ingredients for this Blueberry Croissant French Toast Casserole Recipe are simple but come together in such a delicious way. The croissants soak up the custard perfectly, while the blueberries add a pop of juicy freshness that keeps it from being overly rich. Here’s what I’ve found works best when shopping and prepping.

• Croissants: Fresh or a few days old work best – slightly stale croissants soak up the custard better without turning mushy.
• Eggs: They’re the backbone of the custard, so use large eggs for richness.
• Whole Milk: Warm it slightly so it mixes better with eggs and cream for a silky custard.
• Heavy Cream: Adds the perfect indulgent creaminess that makes this casserole extra luscious.
• Melted Butter: Butter melts into the custard giving it that signature rich flavor and helps the croissants crisp nicely.
• Sugar: Just enough to sweeten but not overpower – I stick to granulated for even sweetness.
• Vanilla Extract: A must-have for that warm, comforting note.
• Ground Cinnamon: It brings a subtle spice that pairs beautifully with the blueberries.
• Fine Sea Salt: A pinch balances the sweetness and helps all the flavors shine.
• Blueberries: Fresh or frozen, these jewels add bursts of natural sweetness and gorgeous color. You can also mix berries if you like.

Variations

I love how flexible the Blueberry Croissant French Toast Casserole Recipe is. Over the years, I’ve experimented with a few tweaks and would encourage you to make it your own! It’s the perfect base to try different berries, spices, or even add-ins.

• Mixed Berry Medley: Swapping in raspberries, blackberries, or strawberries adds complexity and extra color, which I did for a Fourth of July brunch – stunning and delicious!
• Gluten-Free: Use gluten-free croissants if you want to keep this indulgent while avoiding gluten. Just make sure the croissants are sturdy enough to hold the custard.
• Less Sweet: You can reduce the sugar slightly if you prefer to drizzle maple syrup or honey on top instead – gives you more control over sweetness.
• Nutty Touch: Adding chopped toasted almonds or pecans on top before baking gives a wonderful crunch that pairs beautifully with the soft custard.

How to Make Blueberry Croissant French Toast Casserole Recipe

Step 1: Prep Your Pan and Croissants

First things first, preheat your oven to 350°F (175°C) and generously butter a 9″x13″ casserole dish. Butter is key here—it prevents sticking and adds flavor to the edges of your casserole. Then, take your croissants and cut them into roughly 1 to 1.5-inch cubes. I find that cutting them into medium chunks lets you get that perfect mix of crunchy edges and custardy centers. Toss the croissant pieces into your prepared dish and spread them out evenly.

Step 2: Whisk together the Custard

In a large bowl, whisk together the eggs, warm whole milk, heavy cream, melted butter, sugar, vanilla extract, ground cinnamon, and sea salt. Warming the milk just a little warms up the mixture and helps everything combine smoothly without scrambling the eggs. Whisk until the custard is fully blended, and you get a nice cinnamon-speckled mixture.

Step 3: Build the Casserole with Blueberries

Pour the custard over the croissant pieces, gently pressing down with a spatula to help them absorb the liquid. This part is fun—see how the croissants soak up the custard like little sponges! Sprinkle the blueberries evenly over the top and push some gently between layers of croissant so the fruit is baked right in. Let the whole dish sit for about 15 minutes to let the custard soak in fully; if you have more time, cover and refrigerate overnight. Overnight soaking makes the custard even richer and the croissants delightfully tender.

Step 4: Bake It to Golden Perfection

Bake your casserole at 350°F for about 45 minutes. You’re looking for the custard to set completely—no jiggle in the center—and the top to turn a beautiful golden brown. I like to peek around the 40-minute mark because ovens vary, but don’t open the oven too often or the temperature will drop. Once done, let it cool a few minutes before serving so it holds its shape when you cut into it.

How to Serve Blueberry Croissant French Toast Casserole Recipe

Garnishes

I always top mine with a handful of fresh blueberries and a dusting of powdered sugar. Sometimes I add sliced strawberries or a few mint leaves for color and freshness. If you’re feeling indulgent, a drizzle of maple syrup or a dollop of whipped cream takes it to brunch-level deliciousness.

Side Dishes

To round out the meal, I like pairing this casserole with crispy bacon or savory breakfast sausage. A light side salad or fresh fruit bowl is also a nice balance to the richness of the casserole. For a crowd, coffee and orange juice make a perfect pairing.

Creative Ways to Present

For holidays or baby showers, I’ve served this casserole in a beautiful ceramic dish topped with a mix of fresh berries and edible flowers for a show-stopping centerpiece. You can also cut it into smaller squares to create elegant finger food bites at brunch gatherings.

Make Ahead and Storage

Storing Leftovers

Leftover Blueberry Croissant French Toast Casserole keeps well in an airtight container in the fridge for up to 3 days. I like to cover it tightly with foil if I’m leaving it in the casserole dish itself to preserve moisture and prevent the croissants from drying out.

Freezing

If you make a big batch, you can freeze portions individually wrapped in plastic wrap and foil for up to 2 months. I recommend freezing before baking—just thaw overnight in the fridge and bake as usual. This trick has saved me more than once when I’m prepping ahead for holidays!

Reheating

To reheat, I pop leftovers in the oven at 325°F for 10-15 minutes until warm and crisp again. The microwave works in a pinch but can make the croissants a bit soggy. Using the oven helps bring back that freshly baked texture and flavor.
