Rich, delicious French Toast Casserole is over the top made with buttery croissants (regular or gluten-free). Make and bake or make it as an overnight breakfast casserole perfect for weekends or holiday mornings.
In a small saucepan, combine frozen blueberries, sugar and lemon juice. Bring to a low boil over medium heat.
Simmer until the blueberries are soft (approximately 5 minutes). Remove from heat.
In a large mixing bowl, whisk together the eggs, Half and Half, cinnamon, salt, honey, and vanilla.
Pour the remaining egg mixture over the croissants. Cover and place in the refrigerator for 1 hour or overnight (see below).
Cover loosely with foil and bake for 30 minutes. Remove the foil and bake 15 additional minutes until the croissants are golden and crisp.
Serve warm topped with sifted powdered sugar, fresh blueberries, syrup or a scoop of vanilla ice cream!
