This super easy Croissant French Toast Bake is a deliciously decadent dish to prepare for breakfast or brunch. Perfect for the Holidays or special gathering!
Preheat your oven on 180 degrees Celsius / 350 degrees Fahrenheit and prepare a 20 x 30 cm / 8 x 12 inch glass or ceramic baking dish (see note 2).
Cut each croissants into large chunks. Set aside.
In a large bowl, whisk together the eggs, milk, cinnamon, vanilla and salt until you get a smooth mixture. Cinnamon tends to float to the surface, that's normal!
Dip each croissant chunks into the egg mixture and let it soak of a few seconds, then transfer directly into the prepared baking dish. Repeat the process until all the croissants chunks have been soaked and you get a very tightly packed baking dish (see note 3).
Pour the remaining egg mixture over the croissants in the baking dish.
Bake for 45 to 60 minutes or until the top of the croissants are golden and flaky and the custard has fully set.
Allow to cool down for 15 minutes before serving - or store in the fridge covered with plastic wrap (once cooled down) if making in advance.
Optionally dust with powdered sugar once cooler. Serve with your choice of topping.
Notes
The number of croissants needed can vary based on their size. I used relatively large croissants and needed 6 1/2 croissants to make this recipe. If using smaller croissants, increase the quantity up to 8.
I used a 25 x 35 cm (10 x 14 inch) oval dish but any rectangular dish around 20 x 30 cm (8 x 12 inch) will work as well. If using a dish that is larger, you may want to adjust the baking time as the thickness will be thinner and the french toast will bake more quickly.
Depending on the size of your dish and how many croissants you used, the dish may appear more or less packed. If you get less height (when using a larger dish for example), you may need to adjust the baking time slightly.
