Let’s walk through how this recipe comes together: you’ll start by prepping the bread and berries, whisking a custard that’s infused with cinnamon and vanilla, and then giving everything time to mingle in the fridge. Once it’s soaked through, a bake to golden perfection seals the deal. Here’s how to do it step by step:
1. Preheat your oven to 350°F (175°C). Thoroughly grease a 9x13-inch baking dish with butter or non-stick spray to ensure easy serving.
2. In a large mixing bowl, combine the cut French bread cubes and blueberries, gently tossing to distribute the fruit evenly. Transfer this mixture to the prepared baking dish, spreading it in an even layer.
3. In another bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until the mixture is smooth and uniform.
4. Pour the egg mixture evenly over the bread and blueberries. Use a spatula or clean hands to press the bread gently, making sure every cube is soaked in the custard.
5. Cover the baking dish tightly with aluminum foil and refrigerate for at least 1 hour or, for best results, overnight. This resting time helps the bread absorb all the flavorful custard.
6. When ready to bake, remove the dish from the fridge, uncover it, and let it sit at room temperature for about 15 minutes so it cooks evenly.
7. Bake uncovered for 40–45 minutes, until the top turns golden brown and the custard is set in the middle—you can insert a toothpick to check that it comes out clean.
8. Remove from the oven and let it cool for a few minutes. Serve warm, drizzled with maple syrup if you like, dusted with powdered sugar, and garnished with extra blueberries.

Here are answers to the most common questions—no guessing needed!
You’ll need about 15–20 minutes to cube the bread, toss it with blueberries, whisk the custard, and assemble the dish. After assembly, refrigerate for at least 1 hour or up to overnight. Baking takes 40–45 minutes, plus a 10–15 minute resting time before serving.
Absolutely. After pouring the custard over the bread and blueberries, cover the baking dish tightly with foil and refrigerate for 1 hour or overnight. This soaking period ensures the bread absorbs all the custard. When you’re ready to bake, let the dish sit at room temperature for 15 minutes, then remove the foil and bake as directed.
No, you can use frozen blueberries straight from the freezer. Gently toss them with the bread cubes so they stay distributed. They may release a bit of juice as they thaw in the custard, adding extra berry flavor without affecting texture.
Day-old French bread is ideal because it’s sturdy and soaks custard without turning mushy. If unavailable, use a sturdy brioche or challah loaf. Just make sure it’s at least a day old or slightly stale so the custard absorbs evenly.
The top should be golden brown and the custard set without jiggle in the center. Insert a toothpick into the middle—it should come out clean or with just a few moist crumbs but no raw custard.
Cover any leftover casserole tightly and refrigerate for up to 3–4 days. To reheat, slice individual portions and warm in the microwave for 30–60 seconds or in a 325°F oven for about 10 minutes until heated through and slightly crisp on top.
Yes. Swap blueberries for raspberries, strawberries, or mixed berries. For extra flavor, add a teaspoon of lemon zest or a pinch of nutmeg to the custard. You can also swirl in a spoonful of jam or layer sliced fruit between the bread cubes before pouring the custard.
Letting the chilled dish sit at room temperature for about 15 minutes helps the entire casserole bake evenly. If you bake it straight from the fridge, the center may need a few extra minutes to cook through, risking over-browning on top.
This Blueberry French Toast Casserole hits the sweet spot between easy prep and crowd-pleasing flavor—sturdy bread cubes soak up a creamy cinnamon custard, while juicy berries burst in every bite. It’s practically foolproof, holds up beautifully when made ahead, and doubles as dessert or breakfast.
