FAQs

Can I use day-old croissants for this recipe?
Yes, day-old croissants work great! They will soak up the egg mixture even better.

Is it possible to make it dairy-free?
Yes, substitute whole milk with almond or oat milk and use dairy-free cheese.

Can I cook it immediately instead of letting it sit overnight?
While it’s best to let it sit overnight for the best flavor, you can bake it right away. Just make sure to adjust the baking time, as it may need a bit longer.
