Blueberry Lemon French Toast Casserole: From Prep to Plate

Step 1: Prepare the Bread
Begin by preheating your oven to 350°F (175°C). Next, take your Dave’s Killer Blues Bread and cut it into 1-inch cubes. Spread the cubes evenly in your greased 9×13 inch baking dish. This hearty bread will soak up all the delicious custard, making for a satisfying texture.
Step 2: Make the Custard Mixture
In a large mixing bowl, whisk together the eggs, milk, coconut milk, sugar, maple syrup, ground cinnamon, kosher salt, and lemon zest. Make sure everything is well combined; you want a smooth mixture that will envelop the bread and blueberries beautifully.
Step 3: Combine Bread and Custard
Pour the custard mixture evenly over the bread cubes in the baking dish. Using a spatula, gently press down on the bread to ensure that all pieces are soaked in the custard. This step is essential for achieving that creamy texture throughout.
Step 4: Add the Blueberries
Sprinkle the fresh blueberries over the soaked bread, making sure to distribute them evenly. The blueberries will burst during baking, adding juicy pockets of flavor that complement the lemon perfectly.
Step 5: Chill (Optional)
If you’d like to prepare this casserole the night before, cover the baking dish with plastic wrap and refrigerate it overnight. This allows the bread to soak in the custard even more, enhancing the flavors.
Step 6: Bake
Remove the casserole from the refrigerator, if applicable, and uncover it. Bake in the preheated oven for 45-50 minutes, or until the top is golden brown and the custard is set. If you notice the top browning too quickly, you can cover it with aluminum foil for the last 10-15 minutes of baking.
Step 7: Serve
Let the casserole cool for about 10 minutes before slicing into squares. Drizzle with additional maple syrup and serve warm. This Blueberry Lemon French Toast Casserole pairs wonderfully with a side of fresh fruit or a dollop of whipped cream for an extra special touch.
Quick Replacement Ideas

- Milk: Use almond milk or oat milk for a dairy-free version.
- Coconut Milk: Substitute with extra milk if coconut flavor isn’t preferred.
- Maple Syrup: Honey or agave syrup can be used as alternatives.
- Blueberries: Feel free to swap in raspberries or strawberries if you prefer.
What Could Go Wrong
- Overbaking: Keep an eye on your casserole to avoid dryness. The edges should be golden, and the center should be set but not overly firm.
- Not soaking the bread: If the bread cubes aren’t sufficiently coated in custard, they may turn out dry. Ensure even soaking!
- Using stale bread: Fresh bread is ideal, but if you use stale bread, make sure to let it soak longer to achieve the right texture.
- Not enough blueberries: Adjust the amount based on your preference, but a good amount will provide that burst of flavor in every bite.
Save for Later: Storage Tips
If you have leftovers (though it’s hard to imagine!), allow the casserole to cool completely before covering it tightly with plastic wrap or aluminum foil. It will keep in the refrigerator for up to 3 days. To reheat, place individual portions in the microwave for about 30-45 seconds, or reheat in the oven at 350°F (175°C) until warmed through.
Common Qs About Blueberry Lemon French Toast Casserole
Can I use frozen blueberries?
Absolutely! Frozen blueberries work well in this recipe. Just make sure to add them directly from the freezer to prevent excess moisture from leaking into the custard.
Can I make this casserole gluten-free?
Yes! Simply swap out Dave’s Killer Blues Bread for a gluten-free bread of your choice. The rest of the ingredients are naturally gluten-free as well.
How do I know when the casserole is done baking?
The casserole should be golden brown on top, and a knife inserted in the center should come out clean. If it still looks wet, give it a few more minutes in the oven.
Can I add nuts or other toppings?
Certainly! Chopped pecans or walnuts can be sprinkled on top before baking for added crunch. You can also top with powdered sugar or a lemon glaze after baking for a sweet finish.
