How to Make Pioneer Woman Blueberry Lemon French Toast Casserole Overnight Recipe
Step 1: Prepare the Bread Base
Start by cutting your day-old bread into 1-inch cubes. This size is perfect for absorbing the custard without becoming mushy. Place the cubes evenly into a 9×13-inch baking dish so every piece is ready to soak up those amazing flavors.
Step 2: Whisk Together the Custard
In a large bowl, combine the eggs, milk, heavy cream, sugar, lemon zest, fresh lemon juice, vanilla extract, cinnamon, and a pinch of salt. Whisk everything thoroughly until the mixture is smooth and the sugar starts to dissolve. This custard is the magic that transforms the humble bread into a decadently creamy French toast casserole.
Step 3: Assemble and Add Blueberries
Pour the custard evenly over the bread cubes in your baking dish, then gently stir to ensure each piece is coated. Next, sprinkle the fresh blueberries on top and fold them in lightly, spreading the fruit throughout the casserole for bursts of fruity flavor in every bite.
Step 4: Refrigerate Overnight
Cover the baking dish tightly with plastic wrap and place it in the refrigerator overnight. This step allows the bread to soak up all the custard and the lemon and blueberry flavors to meld beautifully, creating a harmonious and perfectly textured casserole.
Step 5: Bake to Golden Perfection
The next morning, remove the cover and bake the casserole uncovered at 350°F (175°C) for 45 to 50 minutes. You want the top to turn a gorgeous golden brown while the inside remains luscious and custardy.
Step 6: Let It Rest and Serve
Allow the casserole to rest for about 10 minutes after taking it from the oven. This resting period helps the dish set up just right, making sure every slice holds together perfectly and is ready to be enjoyed.

Garnishes
Adding the right garnishes takes this casserole from delicious to downright irresistible. A dusting of powdered sugar creates a delicate snow-kissed look, while a few extra fresh blueberries and lemon zest on top add brightness and visual appeal. For an indulgent touch, a drizzle of warm maple syrup or a dollop of whipped cream is simply divine.
Side Dishes
This casserole shines on its own but pairs wonderfully with light sides like crispy bacon or savory breakfast sausages, which provide a salty contrast. A fresh fruit salad is another perfect companion, enhancing the fresh berry and citrus notes in the casserole. For a brunch feast, consider adding coffee or a mimosa for a delightful morning celebration.
Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
If you have leftovers, store them in an airtight container in the refrigerator. The casserole keeps well for up to 3 days, making it a convenient option for quick breakfasts or snacks that still taste fresh and flavorful.
Freezing
You can freeze leftover portions by wrapping them tightly in plastic wrap and placing them in a freezer-safe bag or container. Frozen casserole pieces can be stored for up to 2 months, perfect for busy mornings when you need a fast, satisfying breakfast.
Reheating
Reheat refrigerated or thawed casserole slices gently in the microwave or oven. To keep the top from drying out, cover lightly with foil if reheating in the oven at 325°F until warmed through. This method helps maintain that creamy, custardy goodness and crispy edges without sacrificing texture.
FAQs
Can I use frozen blueberries instead of fresh?
Yes, frozen blueberries can be used if fresh ones aren’t available. Just thaw and drain them before adding to the casserole to avoid excess moisture, which could make the dish soggy.
Is it necessary to use day-old bread?
Using day-old or slightly stale bread is best because it absorbs the custard without becoming mushy. Fresh bread tends to soak up too much liquid and fall apart during baking, so if you must use fresh, consider toasting it lightly first.
Can I make this recipe dairy-free?
Absolutely! Substitute the milk and heavy cream with your favorite dairy-free alternatives like almond milk, oat milk, or coconut cream. The flavor might slightly change, but the casserole will remain delicious.
How long should the casserole soak overnight?
Ideally, refrigerate the casserole for at least 6 to 8 hours. This ensures the bread absorbs the custard fully and the flavors meld perfectly, making each bite rich and cohesive.
Can I prepare this casserole without blueberries?
Yes, though blueberries add a wonderful fresh flavor and texture contrast. You could substitute other fruits like raspberries, strawberries, or even diced peaches, depending on your preference and seasonality.
