Ingredients

Main Ingredients

5-6 large croissants (fresh or a few days old)
5 eggs
1 cup whole milk (warm)
1/2 cup heavy cream
4 tbsp melted butter
1/3 cup sugar
2 tsp vanilla extract
2 tsp ground cinnamon
1/2 tsp fine sea salt
2 cups blueberries or mixed berries (plus more for garnish, such as strawberries, blackberries, raspberries)

Instructions

Prep the Oven and Dish: Preheat your oven to 350°F (175°C) and generously butter a 9″x13″ casserole baking dish to prevent sticking and ensure easy serving.
Cut Croissants: Slice the croissants into small cubes about 1 to 1.5 inches in size, then evenly distribute them in the prepared baking dish.
Prepare the Custard Mixture: In a bowl, whisk together the eggs, warm whole milk, heavy cream, melted butter, sugar, vanilla extract, ground cinnamon, and fine sea salt until smooth and well combined.
Assemble the Casserole: Pour the custard mixture evenly over the croissant pieces. Use a spatula to press down gently, helping the croissants absorb the custard. Scatter blueberries on top and tuck some between the croissant layers for bursts of fruity flavor. Let the casserole sit for 15 minutes at room temperature; for best results, refrigerate overnight to allow full absorption.
Bake the Casserole: Place the dish in the preheated oven and bake for 45 minutes, or until the custard is fully set and the top is golden brown. Serve warm, garnished with additional fresh berries if desired.

Notes

For best texture and flavor, use day-old croissants, which absorb the custard better without becoming mushy.
Letting the casserole soak overnight in the fridge enhances custard absorption and melds the flavors beautifully.
You can swap blueberries with any mixed berries or stone fruits like peaches for seasonal variations.
This recipe can be prepared ahead and refrigerated before baking, making it convenient for busy mornings.
Serve with maple syrup, powdered sugar, or whipped cream for extra indulgence.
