Ingredients
- 1 (13-16 ounce) loaf challah or brioche bread, cut into 1-inch cubes (about 8-10 cups)
- 2 cups fresh or frozen blueberries
- 8 large eggs
- 2 cups whole milk
- 1/2 cup heavy cream (or more milk for a lighter version)
- 1/2 cup granulated sugar
- 2 teaspoons vanilla extract
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- Pinch of salt
- For the Topping:
- 1/2 cup all-purpose flour
- 1/2 cup packed light brown sugar
- 1/4 cup granulated sugar
- 1 teaspoon ground cinnamon
- 1/2 cup (1 stick) cold unsalted butter, cut into small pieces
- Optional: 1/2 cup chopped pecans or almonds
- For Serving:
- Powdered sugar
- Maple syrup
Instructions
- Lightly grease a 9×13 inch baking dish with butter or non-stick spray.
- Arrange half of the bread cubes evenly in the prepared baking dish. Scatter 1 cup of blueberries over the bread.
- Layer the remaining bread cubes over the blueberries, then scatter the remaining 1 cup of blueberries on top.
- In a large bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined.
- Pour the egg mixture evenly over the bread and blueberries in the baking dish, making sure all the bread is soaked. Gently press down on the bread with the back of a spoon to ensure it absorbs the liquid.
- Cover the baking dish tightly with plastic wrap and refrigerate for at least 4 hours, or preferably overnight (up to 24 hours).
- About 30 minutes before baking, remove the casserole from the refrigerator to come to room temperature. Preheat your oven to 375°F (190°C).
- Prepare the streusel topping: In a medium bowl, combine the flour, brown sugar, granulated sugar, and cinnamon. Add the cold butter pieces and, using your fingertips or a pastry blender, cut the butter into the dry ingredients until the mixture resembles coarse crumbs. If using, stir in the chopped pecans or almonds.
- Sprinkle the streusel topping evenly over the French toast casserole.
- Bake for 45-55 minutes, or until the casserole is golden brown, puffed, and a knife inserted into the center comes out clean (no raw egg mixture). If the topping starts to brown too quickly, you can loosely tent it with aluminum foil.
- Let the casserole rest for 10 minutes before serving. Dust with powdered sugar and serve warm with a generous drizzle of maple syrup.
Tips & Variations
- Smart Bread Choice: For a quick, perfect result, use challah or brioche. Day-old bread is your best friend here – it soaks up all that delicious custard without getting mushy, guaranteeing a perfect texture every time.
- The Overnight Advantage: Don’t skip the overnight chill! This is where the magic happens, ensuring every bite is infused with flavor. It’s your ‘5-minute’ secret to a truly decadent outcome with zero morning fuss.
- Berry Quick Swaps: Blueberries are divine, but feel free to quickly swap in any berries you have on hand – raspberries, sliced strawberries, or a frozen berry blend work beautifully for instant variety.
- Batch & Breeze: This casserole is ideal for effortlessly feeding a crowd. Double the recipe and use two dishes for a stress-free brunch that looks impressive but was a cinch to prepare.
- Speedy Leftover Revival: Store any extra in an airtight container for up to 3 days. Reheat individual portions in the microwave for a super-fast, comforting breakfast treat whenever a craving strikes!
