Ingredients

For this Blueberry Lemon French Toast Bake, you’ll need:

• 1 large loaf (16-18 oz) day-old challah or brioche bread, cut into 1-inch cubes (slightly stale bread absorbs the custard better)
• 2 cups fresh blueberries (or frozen, not thawed)
• 8 large eggs
• 2½ cups whole milk
• ½ cup heavy cream
• ¾ cup granulated sugar
• 2 tablespoons fresh lemon zest (from about 2 medium lemons)
• ¼ cup fresh lemon juice
• 1 tablespoon pure vanilla extract
• ½ teaspoon ground cinnamon
• ¼ teaspoon salt
• 2 tablespoons turbinado sugar (for topping)

For the optional lemon glaze:

• 1 cup powdered sugar
• 2-3 tablespoons fresh lemon juice
• ½ teaspoon lemon zest

Pro Tips

Achieving the perfect Blueberry Lemon French Toast Bake comes down to mastering a few key techniques:

Use Day-Old Bread: Fresh bread will become too soggy when soaked in the custard mixture. Day-old or slightly stale bread maintains its structure while still absorbing the flavorful liquid. If you only have fresh bread, cube it and leave it out uncovered for a few hours, or toast it in a 275°F oven for 10 minutes to dry it out slightly.

Don’t Skip the Overnight Soak: While you can bake this dish immediately after assembly, allowing it to rest in the refrigerator overnight produces a significantly better texture and flavor profile. This resting period gives the bread time to fully absorb the custard mixture and allows the lemon and blueberry flavors to meld beautifully.

Master the Baking Technique: Start baking your French toast covered with foil to prevent over-browning, then remove the foil during the last 15-20 minutes to achieve that perfectly golden, slightly crispy top. The center should be set but still moist – if it’s jiggly, it needs more time. Using an instant-read thermometer to check for an internal temperature of 160°F ensures food safety while preventing overcooking.

Instructions

Step 1: Prepare the Baking Dish

Generously butter a 9×13-inch baking dish, making sure to coat the sides as well as the bottom. This prevents sticking and adds a subtle richness to the outer edges of your Blueberry Lemon French Toast Bake. If you’re planning to serve directly from the dish, consider using a pretty ceramic baking dish that can go from oven to table.

Step 2: Arrange the Bread and Berries

Spread half of your bread cubes in an even layer in the prepared baking dish. Scatter 1 cup of blueberries over the bread, then add the remaining bread cubes on top. Sprinkle the remaining cup of blueberries over everything. This layering technique ensures the berries are distributed throughout the entire bake rather than sinking to the bottom.

Step 3: Create the Custard Mixture

In a large bowl, whisk together the eggs, milk, heavy cream, granulated sugar, lemon zest, lemon juice, vanilla extract, cinnamon, and salt until completely combined. Take your time with this step – a thoroughly mixed custard ensures even flavor throughout your Blueberry Lemon French Toast Bake. The mixture should be smooth with the sugar fully dissolved.

Step 4: Combine and Soak

Pour the custard mixture evenly over the bread and blueberries, making sure all bread pieces get saturated. Gently press the bread down with a spatula to help absorption. Cover the dish with plastic wrap and refrigerate for at least 2 hours or overnight (preferred). This resting time is crucial for the bread to soak up all those wonderful flavors.

Step 5: Bake to Perfection

When you’re ready to bake, preheat your oven to 350°F and remove the dish from the refrigerator to take off the chill while the oven heats up. Sprinkle the turbinado sugar evenly over the top for a delightful crunch. Cover with aluminum foil and bake for 30 minutes. Then remove the foil and bake for an additional 25-30 minutes until the top is golden brown and the center is set but still slightly moist.

Step 6: Prepare the Optional Glaze

While the Blueberry Lemon French Toast Bake is cooling, whisk together the powdered sugar, lemon juice, and lemon zest in a small bowl until smooth. Adjust the consistency by adding more lemon juice if too thick or more powdered sugar if too thin. It should be pourable but not runny.

Step 7: Finish and Serve

Let the bake cool for about 10 minutes before drizzling with the lemon glaze if using. This brief cooling period allows the custard to set up slightly, making it easier to portion. Serve warm with maple syrup, a dollop of whipped cream, or additional fresh berries for the ultimate breakfast experience.

Variations

Mixed Berry Delight: Transform this Blueberry Lemon French Toast Bake by using a combination of strawberries, raspberries, and blackberries alongside the blueberries. This colorful variation adds different flavor notes and makes for a stunning presentation, especially for summer brunches. The mixed berries create beautiful pockets of jewel-toned fruit throughout the bake.

Dairy-Free Adaptation: Create a dairy-free version by substituting the whole milk and heavy cream with full-fat coconut milk or almond milk, and use dairy-free butter for greasing the dish. The coconut milk adds a subtle tropical note that pairs wonderfully with the lemon and blueberries, while still maintaining the rich, custard-like texture essential to a good French toast bake.

Orange-Cranberry Twist: For a holiday version, swap the lemon zest and juice for orange, and replace blueberries with fresh or frozen cranberries. Add ½ teaspoon of ground nutmeg to the custard mixture and finish with a sprinkle of chopped pecans before baking. This festive variation makes a spectacular Christmas morning breakfast that fills your home with warming holiday aromas.

Storage and Serving

Store any leftover Blueberry Lemon French Toast Bake covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 60-90 seconds until warmed through, or place the entire bake (covered with foil) in a 325°F oven for about 15-20 minutes. The flavor actually improves after the first day as the lemon notes mellow and integrate more fully.

For an elegant brunch presentation, serve slices with a dusting of powdered sugar, a side of warm maple syrup, and fresh blueberries. Add a dollop of lemon-infused whipped cream by folding a teaspoon of lemon zest into whipped cream for an extra special touch.

This dish pairs beautifully with savory breakfast sides like crispy bacon or breakfast sausage to create a balanced meal. For a special occasion brunch, complement it with a chilled prosecco mimosa featuring a splash of blueberry juice for a color-coordinated, festive touch.

FAQs

Can I use frozen blueberries instead of fresh?
Yes, frozen blueberries work perfectly in this Blueberry Lemon French Toast Bake. Use them directly from the freezer without thawing to prevent color bleeding throughout the custard. You may need to add 5-10 minutes to the baking time if using frozen berries.

Can I prepare this without an overnight soak?
While an overnight soak yields the best results, you can prepare and bake this immediately. Allow at least 30 minutes of soaking time at room temperature so the bread can absorb some of the custard mixture before baking.

What’s the best bread to use?
Challah and brioche are ideal because of their buttery richness and ability to absorb custard while maintaining structure. French bread or sourdough are good alternatives if you prefer a less sweet base.

Can I make this recipe gluten-free?
Absolutely! Substitute your favorite gluten-free bread, ensuring it’s slightly stale or toasted first. The texture may be slightly different, but the flavor will still be delicious.

How do I know when it’s done baking?
The top should be golden brown and slightly crisp, while the center should be set but still moist. An instant-read thermometer inserted in the center should read 160°F. If the top browns too quickly, cover loosely with foil.

Conclusion

This Blueberry Lemon French Toast Bake is comfort food at its finest — a perfect balance of bright citrus notes and sweet berry bursts wrapped in a custardy, bread pudding-like embrace. It’s the kind of dish that transforms ordinary mornings into memorable gatherings, bridging the gap between everyday breakfast and special occasion brunch.
