Ingredients
- Whole Milk
- Granulated sugar
- Large eggs
- Lemon zest
- Vanilla extract

Cooking Tips
- For this blueberry baked french toast fresh croissants are fine to use but day-old stale croissants work best to soak up the lemon scented custard.
- You can also use either homemade lemon curd or a good store-bought lemon curd
- Both fresh berries or frozen blueberries work well.
How to Make Blueberry Lemon Croissant French Toast Casserole
This french toast bake starts with making a simple creamy custard mixture with milk and eggs. In a large bowl whisk together the milk eggs, sugar, lemon zest and vanilla extract until smooth and creamy. If using large croissants tear or cut them into smaller pieces, if using smaller mini croissants you can keep them whole. Dip each croissant into the milk and egg mixture and layer them in a 9×13 inch baking dish prepared with butter or cooking spray, then pour in the remaining custard mixture over the croissants. Add in the blueberries throughout the croissants and place spoonfuls of lemon curd inbetween and on top of the croissants. Cover with aluminum foil and refrigerate for at least one hour or up to overnight to allow the croissants to soak up the custard.


Preheat the oven to 350 degrees F and allow the french toast to come to room temperature for at least 15 minutes. Remove the aluminum foil and bake for 35 minutes or until the top is golden. Allow to cool for 10 minutes and serve as desired.
I recommend a dusting of powdered sugar over the french toast or top with fresh blueberries, blueberry sauce, additional lemon curd, whipped cream or maple syrup!
