Ingredients for Croissant Casserole

Simple and easy – that’s what I love about this French toast recipe! You’re sure to have all the ingredients you need to make this recipe already. For the full list of ingredients, head down to the recipe card below.

  • Croissants – I like to use medium-sized, day-old croissants for this recipe. Stale or dry croissants will be easier to cut and will absorb more of the egg custard. You can also use other types of bread for this recipe; brioche bread will also work well.
  • Eggs – while I recommend room temperature eggs for most of my recipes, you can use cold eggs for this one, too.
  • Milk & Cream – using a combination of these two makes for a richer tasting casserole!
  • Pure Maple Syrup – adds tons of great flavor! Pure maple syrup has no corn syrup or artificial flavors and is the best option.
  • Ground Cinnamon – you can also add a touch of ground nutmeg.
  • Berries – I used a combination of fresh raspberries, blueberries, and strawberries. Frozen and thawed berries will also work well. If you’re making an overnight casserole, frozen berries will work.

Preparing Your Casserole Dish.

Start by preheating your oven to 375F. You can use a large oval, round or square casserole dish for this recipe. Spray the inside of the dish with a baking spray and brush it evenly over the dish.

Using a baking spray will prevent the caramelized sugars from sticking to the bottom and sides of the casserole dish, making for an easier cleanup! You can also line the sides with parchment paper (easier for a square pan).

Making the Easy Egg Custard

I start this overnight croissant French toast casserole with the egg custard! We’ll dip the croissants into this custard. Here’s how to make it.

  1. Break the eggs into a large mixing bowl and add in the maple syrup, sugar, vanilla extract, salt and ground cinnamon. Use a whisk to beat the eggs for a few minutes, until they’re well beaten.
  2. Next, pour in the milk and cream. You can use all milk (for less calories), or all cream (for a richer tasting toast).
  3. Whisk the eggs and dairy together, then set aside the custard.

Preparing the Croissants

Once you have the custard ready to go, it’s time to prepare the croissants. You can also use this recipe with brioche bread, or a thicker cut French bread.

Using a serrated knife, carefully split each croissant in half lengthwise. If you’re croissants are extra-large, you can also split in them in half vertically so the casserole is easier to serve.

How to Make Croissant French Toast Casserole

Now, lets put it all together! You’ll love how easy it is to make this French toast casserole!

  1. Prepare the berries by washing them first. If adding strawberries, section them into smaller pieces.
  2. Drop one piece of halved croissant at a time into the prepared egg custard, allowing the bread to become well saturated with the mixture.
  3. Layer the croissants into the prepared casserole dish, adding a small handful of berries with each croissant. I like to add the berries in between the halves, too. Continue with these steps until the entire casserole is filled.
  4. Pour any remaining custard over the top of the casserole and sprinkle more berries over the top.
  5. Cover the casserole with foil and bake the French toast at 375F for 35 to 40 minutes, until the custard is completely set. Remove the foil for the last 6 to 8 minutes, to allow the croissants to become golden brown.

  2. In the morning, remove the casserole from the refrigerator while you’re preheating the oven.
  3. Bake the casserole at 375F for about 50 minutes; you’ll need the additional 10 to 15 minutes time since the bread will be cold out of the fridge.

Serving the Croissant French Toast

Once the croissant casserole is done, dig right in! I recommend serving it right away or keeping it warm until you’re ready to serve. Add a few dabs of butter on top while it’s still warm.

Using a large spoon, scoop out each croissant onto a serving plate. Add a drizzle of pure maple syrup and more fresh berries, then enjoy!
