Step‑by‑Step Instructions for Blueberry French Toast Casserole
Step 1: Preparation
Preheat your oven to 350°F (175°C). While the oven is heating, grab a 9×13 inch baking dish and grease it generously with butter or cooking spray to prevent sticking. Cut the challah or brioche bread into cubes, about 1-inch in size, and spread them evenly across the bottom of the dish. Gently scatter fresh blueberries over the top, ensuring a good distribution for optimal flavor in your Blueberry French Toast Casserole.
Step 2: Make Custard
In a large mixing bowl, whisk together 4 large eggs, 2 cups of milk, and 1 cup of heavy cream until the mixture is smooth and well combined. Add in 1/2 cup of maple syrup, 1 tablespoon of vanilla extract, 1 teaspoon of ground cinnamon, and a pinch of salt. Continue whisking until all the ingredients are fully incorporated, creating a rich custard that will bring your casserole to life.
Step 3: Combine & Soak
Pour the prepared custard mixture evenly over the bread cubes and blueberries in the baking dish. Make sure each piece of bread is soaked thoroughly by gently pressing down with a spatula or spoon. To achieve the best flavor and texture, let the casserole sit for 30 minutes at room temperature to soak up the custard. For an even more indulgent result, cover and refrigerate it overnight, allowing the ingredients to meld beautifully.
Step 4: Bake
Once your casserole has soaked, place it in the preheated oven and bake for 45 to 50 minutes. You’ll know it’s ready when the top is golden brown and a toothpick inserted in the center comes out clean. The casserole should puff up beautifully, creating a delightful contrast between a crunchy top and a soft, custardy interior that defines this Blueberry French Toast Casserole.
Step 5: Serve
Remove the casserole from the oven and allow it to cool slightly for about 10 minutes. This will help it set and make slicing easier. Serve warm, dusted with powdered sugar if desired, and accompanied by a drizzle of maple syrup and generous dollops of whipped cream for added indulgence. Enjoy this warm, comforting dish with family and friends!
