How to Make the Recipe

Step 1: Prepare the Custard

In a large bowl, whisk together half and half (or milk), eggs, vanilla extract, brown sugar, cinnamon, nutmeg, and salt until smooth and combined.

Step 2: Assemble the Casserole

Place the halved croissants in a greased baking dish, cut side up. Distribute the strawberries and blueberries evenly between the croissants. Pour the custard mixture evenly over the croissants, ensuring all pieces are well soaked.

Step 3: Soak

Cover and refrigerate for at least 2 hours or overnight to allow the croissants to absorb the custard fully.

Step 4: Bake

Preheat the oven to 350°F (175°C). Remove the casserole from the fridge and bake uncovered for 45–50 minutes until golden brown and the custard is set.

Step 5: Make the Rum Maple Syrup

While the casserole bakes, gently warm the maple syrup in a small saucepan. Stir in dark rum and heat through but do not boil. Remove from heat and set aside.

Step 6: Serve

Dust the casserole with powdered sugar. Serve warm topped with whipped cream (if using) and drizzle generously with rum maple syrup.

Tips for Making the Recipe

Use day-old or slightly stale croissants for better soaking and texture.

Soaking overnight improves custard absorption and flavor.
Avoid overcrowding croissants in the dish to ensure even soaking.
Adjust the amount of brown sugar based on desired sweetness.

Keep an eye on the casserole near the end of baking to prevent over-browning.

How to Serve

Serve this French Toast Casserole warm, ideally with a dollop of whipped cream and a drizzle of the rum maple syrup. Pair it with fresh fruit, crispy bacon, or sausage for a well-rounded brunch spread. It also pairs nicely with a hot cup of coffee or freshly squeezed juice.
