Main Ingredients
- 6–8 fresh buttery croissants, roughly torn into bite-sized chunks
- 6 large eggs
- 1 cup whole milk
- 1 cup heavy cream
- 1/2 cup granulated sugar
- 1 teaspoon ground cinnamon
- 1 teaspoon pure vanilla extract
- 1/4 teaspoon salt
- 2 tablespoons unsalted butter, cut into small pieces
Optional Toppings
- Sliced almonds
- Fresh berries (such as blueberries, raspberries, or strawberries)
- Maple syrup
- Powdered sugar
- Prepare the Croissants: Roughly tear or cut the croissants into bite-sized chunks to create plenty of surface area for soaking up the custard.
- Whisk Custard Ingredients: In a large bowl, whisk together the eggs, milk, heavy cream, sugar, cinnamon, vanilla extract, and salt until the mixture is smooth and well combined.
- Combine and Soak: Place the croissant pieces evenly in a greased baking dish. Pour the custard mixture over the croissants, then gently press them down to help absorb the custard. Cover the dish and refrigerate for at least 2 hours or overnight for best results.
- Add Butter and Bake: Before baking, dot the top of the casserole with small pieces of butter. Bake in a preheated oven at 350°F (175°C) for 45-50 minutes, until the top is puffed, golden brown, and the custard is set.
- Let It Rest and Serve: Let the casserole rest for a few minutes after baking to firm up slightly, making it easier to slice and serve. Add desired toppings such as powdered sugar, fresh berries, or maple syrup before serving.
Notes
- Use day-old croissants for better custard absorption without becoming mushy.
- Refrigerate the assembled casserole overnight for richer flavor and cohesive texture.
- Use high-quality pure vanilla extract to elevate the flavor.
- Ensure croissant pieces are spread evenly for consistent soaking and fluffiness.
- Monitor baking time towards the end to avoid over-browning; use a foil tent if needed.
