Ingredients You’ll Need

Believe it or not, this simple blueberry French toast casserole comes together with just six simple ingredients. Here’s everything you need:

Croissants – Large croissants replace bread for an extra crisp exterior and a pillowy center. For the finest results, allow them to become slightly stale.
Milk – We recommend using whole milk for the richest taste. However, any milk you have on hand will work.
Eggs – These are crucial to form the custard, allowing the liquid to bake and set.
Sugar – Regular granulated sugar helps sweeten the custard for a dessert-like breakfast.
Vanilla Extract – High-quality vanilla extract helps enhance the flavor of the rest of the ingredients.
Blueberries – We prefer to use fresh blueberries, but frozen work, too. You don’t even have to thaw them! Just dust off any ice particles, and add them to the dish.

Simple Steps for the Finest Blueberry French Toast Bake

Create the silky custard. In a large mixing bowl, whisk the milk, eggs, sugar, and vanilla until well combined.
Cut the croissants. Slice each croissant into three pieces, and arrange them in a single layer in a large casserole dish.
Combine the ingredients. Sprinkle the blueberries over the croissants. Then, pour the egg mixture on top, coating the croissants completely. Press the pieces down gently to ensure they absorb the liquid.
Soak. Cover the baking dish, and transfer it to the fridge for at least two hours.
Bake. Place the blueberry French toast in a preheated oven. Bake until the top is golden brown and the custard sets.
Cool and serve. Remove the dish from the oven, allow the French toast to cool slightly, and serve warm drizzled with maple syrup, if desired.

Tips to Prevent Soggy French Toast

No one likes soggy French toast! Luckily, it’s simple to avoid.

Use stale croissants. They will be a bit dry and easily absorb the liquid.
Avoid using too much custard. You want the mixture to completely coat the croissants, but they shouldn’t be drowning in liquid.
Bake long enough. Be sure to allow your blueberry French toast to bake long eno

How to Make Stale Croissants in Minutes

Don’t have time for your croissants to turn stale? We’ve got a trick for you!

Arrange two racks on the upper and lower portion of your oven.
Preheat the oven to 350 degrees Fahrenheit.
Place the croissant pieces on a baking sheet, and transfer them to the oven for about ten minutes, tossing halfway through. By the end, the bread will dry out and become perfectly stale!

Common Questions About This Blueberry French Toast Casserole Recipe

Why use croissants instead of regular bread?

Croissants make it extra special! They’re buttery, flaky, and soak up the custard beautifully while still keeping some texture. It’s like leveling up French toast with pastry vibes.

What kind of milk should I use?

Whole milk or half-and-half gives the richest custard, but you can totally use almond, oat, or other non-dairy options if you’d like. Just be sure it’s unsweetened so you can control the sweetness.

Does it need a topping?

It’s memorable as-is, but you can definitely add a crumbly streusel topping, a drizzle of maple syrup (like we do!), powdered sugar, or even a dollop of whipped cream. No wrong choices here!

Is it good leftover?

Yes, and maybe even better! Reheat in the oven or air fryer to crisp it up a bit, or microwave it for a soft and cozy bite. Add syrup and it’s like breakfast round two.
