Ingredients:

How to Make Croissant French Toast Casserole
- Preheat the oven to 350ยฐF. Grease a 9x13-inch casserole dish with butter or nonstick spray.
- Cut the croissants into large chunks and arrange them evenly in the prepared baking dish.
- In a large bowl, whisk the eggs, milk, vanilla extract, brown sugar, cinnamon, and salt until fully combined.
- Pour the egg mixture evenly over the croissants, ensuring all pieces are coated. Gently press down on the croissants to help them absorb the liquid. Let sit for 30 minutes, or cover and refrigerate overnight for enhanced flavor.
- Place the dish in the preheated oven and bake for 35-40 minutes, or until the top is golden brown and the custard is set. If the top browns too quickly, tent loosely with foil for the last 10 minutes of baking.
- Remove from the oven and let cool for a few minutes. Dust with powdered sugar or drizzle with pure maple syrup before serving. Serve warm.

Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days or freeze for up to 2 months.
To reheat, microwave individual servings forย 30-45 secondsย or warm in aย 350ยฐF oven for 10-15 minutes. If frozen, thaw in the fridge overnight before reheating.

Quick Tips
- Day-Old Croissants Work Best - Slightly stale croissants absorb the custard better, creating the perfect texture.
Use Whole Milk for Richness - You can substitute with half-and-half for an extra indulgent casserole or use almond milk for a lighter breakfast. - Let It Soakย - For best results, allow the croissant pieces to absorb the custard for at least 30 minutes before baking.
