Baked Blueberry French Toast Casserole Ingredients

• Unsalted butter, room temperature, for baking dish
• 6 large eggs
• 3 cups whole milk
• ⅓ cup sugar
• ½ teaspoon ground cinnamon
• ½ teaspoon coarse salt
• 10 ½-inch-thick slices brioche (from one 10-ounce loaf)
• 1 cup blueberries
• Confectioners’ sugar, for serving

How To Make Baked Blueberry French Toast Casserole

1. Prep the dish and make the custard: Generously butter a shallow 2-quart baking dish. In a large bowl, whisk together the eggs, milk, sugar, cinnamon, and salt until well combined.
2. Soak the bread: Dip each slice of brioche into the egg mixture, then arrange the slices in the prepared dish, overlapping them slightly. Pour any remaining egg mixture evenly over the top of the brioche.
3. Rest the casserole: Cover the dish with plastic wrap and let it stand at room temperature for 30 minutes, or refrigerate for up to one day.
4. Add blueberries and bake: Preheat the oven to 325°F. Sprinkle the blueberries in between and on top of the bread slices. Bake for 55 to 65 minutes, until the casserole is puffed and the custard is just set. If the top begins to brown too quickly, you can tent it loosely with foil.
5. Cool and serve: Let the casserole cool on a wire rack for 15 minutes. Dust with confectioners’ sugar just before serving.

Recipe Tips

• How to prevent a soggy casserole? Using slightly stale or day-old brioche is a great trick. It’s a bit drier, so it can absorb more of the custard without becoming overly soft or falling apart.
• Can I use a different kind of bread? Yes, if you can’t find brioche, a thick-cut challah or a good quality Texas toast would be excellent substitutes.
• Can I use frozen blueberries? Absolutely. There is no need to thaw the blueberries first. Simply sprinkle them directly from the freezer over the casserole before baking.
• Why is it important to let the casserole rest before baking? Letting it stand for at least 30 minutes (or overnight) is a crucial step. It gives the bread time to fully absorb the custard, which ensures a creamy, consistent texture and prevents a layer of unabsorbed liquid at the bottom of the dish.

What To Serve With French Toast Casserole

This is a complete breakfast dish on its own, but it’s even more delicious with a few simple additions.

• A drizzle of warm maple syrup
• A side of crispy bacon or sausage links
• A fresh fruit salad
• A dollop of fresh whipped cream

How To Store French Toast Casserole

• Refrigerate: Store leftovers tightly covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave or place the entire dish back in a 350°F oven until warmed through.
