Ingredients for Blueberry French Toast Casserole
Gather these simple ingredients for a delightful French toast casserole with blueberries. The beauty of this dish is how common pantry staples transform into something truly special. Using day-old bread is key, as it soaks up the custard beautifully without getting soggy. Fresh or frozen blueberries both work wonderfully, adding bursts of sweet-tart flavor throughout the casserole.
- 1 loaf brioche or French bread, cubed (about 10-12 cups) – stale is best for soaking
- 1 1/2 cups fresh or frozen blueberries – adds pops of juicy flavor
- 8 large eggs – the base for our rich custard
- 2 cups whole milk – for a creamy texture
- 1/2 cup heavy cream – adds extra richness and a velvety mouthfeel
- 1/2 cup granulated sugar – balances the tartness of the berries
- 1 tbsp pure vanilla extract – essential for that classic French toast flavor
- 1 tsp ground cinnamon – a warm spice that complements the blueberries
- Zest of 1 lemon (optional) – brightens the flavors beautifully
How to Make Blueberry French Toast Casserole
Get ready to create a breakfast masterpiece! This recipe guides you through making the most delicious Overnight Blueberry French Toast Casserole. The process is straightforward, and the results are incredibly rewarding.

- Step 1: Start by preparing your baking dish. Generously butter or spray a 9×13-inch baking dish. This prevents sticking and ensures a lovely golden crust.
- Step 2: Layer the foundation of your casserole. Scatter half of the cubed bread evenly in the prepared dish. Then, sprinkle 1 cup of blueberries over the bread. Repeat this layering with the remaining bread and blueberries.
- Step 3: Whisk together the custard base. In a large bowl, whisk the 8 large eggs until they are smooth and well combined. Slowly stream in the 2 cups whole milk and 1/2 cup heavy cream while continuing to whisk.
- Step 4: Add the flavorings. Stir in the 1/2 cup granulated sugar, 1 tbsp pure vanilla extract, 1 tsp ground cinnamon, and the lemon zest (if you’re using it). Whisk everything until it’s thoroughly combined.
- Step 5: Pour the custard over the bread and berries. Slowly and evenly pour the rich custard mixture over the bread and blueberries in the baking dish. Gently press down on the bread cubes with a spatula to help them soak up all that delicious custard, ensuring every bite is moist and flavorful.
- Step 6: Chill for maximum flavor absorption. Cover the dish tightly with plastic wrap. Refrigerate for at least 2 hours, but for the absolute best flavor and texture, let it sit overnight. This allows the bread to fully absorb the custard, transforming it into a delightful blueberry bread pudding casserole.
- Step 7: Prepare for baking. When you’re ready to bake, remove the casserole from the refrigerator about 20-30 minutes beforehand to let it come closer to room temperature. Preheat your oven to 350°F (175°C).
- Step 8: Bake to golden perfection. Remove the plastic wrap from the dish. Bake, uncovered, for 45-50 minutes. You’re looking for the top to be beautifully golden brown and the center to be fully set, with no liquid custard remaining.
- Step 9: Let it rest. Once baked, allow the casserole to rest for 10-15 minutes. This resting period is crucial for the casserole to set up properly, making it easier to slice and serve.
- Step 10: Serve and enjoy! Dust the top with powdered sugar and serve warm with pure maple syrup.
Pro Tips for the Best Blueberry French Toast Casserole
Achieving a truly exceptional Blueberry French Toast Casserole is all about a few simple tricks. These tips will elevate your breakfast bake from good to absolutely unforgettable. Trust me, I’ve learned a few things over the years that make all the difference!
- Always use slightly stale bread; it soaks up the custard like a sponge without getting mushy. Day-old brioche or challah is perfect.
- Don’t skip the overnight chilling! This is crucial for allowing the bread to fully absorb the custard, leading to a richer flavor and perfect texture.
- Ensure your oven is fully preheated to the correct temperature. An oven that’s too cool can result in a soggy casserole instead of a beautifully golden one.
- Let the casserole rest after baking. This allows it to set up properly, making it easier to serve neat slices.
