We’re big breakfast people, and French toast is one of our favorite recipes. With endless options like cannoli baked French toast, bananas foster French toast, and churro French toast, we never get bored!

Plus, it’s such an easy option to prepare in advance and always makes enough to feed the whole family. So, with summer in full swing, it only makes sense to take advantage of our favorite fruit with this blueberry French toast recipe!

It’s crispy on the outside, fluffy in the center, and full of plump blueberries. As a result, it totally elevates your average French toast recipe to a whole new level. It’ll be your new go-to for weekend brunches, holiday gatherings, and weekday breakfasts, too!

Ingredients You’ll Need

Believe it or not, this easy 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 best 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 Best Blueberry French Toast Bake

Create the creamy 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 easy 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
