Blueberry Lemon French Toast Casserole Ingredients
For the Cream Cheese Filling
- Cream Cheese – Adds creaminess. Substitution: Use dairy-free cream cheese for a lactose-free version.
- Powdered Sugar – Provides sweetness and helps to create a smooth filling. Substitution: No direct substitute for the texture but can reduce for less sweetness.
- Milk – Moistens the bread and filling. Substitution: Almond or oat milk can be used for a dairy-free option.
- Vanilla Extract – Enhances overall flavor. No substitutions recommended for best results.
- Blueberries – Add natural sweetness and tartness. Substitution: Fresh or frozen blueberries work; do not thaw frozen ones before use.
For the Casserole Base
- French Bread – Provides structure and absorbs egg mixture well. Substitution: Brioche for a richer flavor, avoid sourdough as it may clash with lemon.
- Eggs – Binds and gives structure to the casserole. No substitution unless using egg replacements like flax eggs (note: texture may vary).
For Flavor Enhancement
- Cinnamon – Adds warmth and flavor. Optional for those who prefer a milder taste.
- Nutmeg – Offers a nutty and sweet aroma. Completely optional; skip if undesirable.
- Lemon (zest + juice) – Contributes tanginess and bright flavor. Use additional lemon for more zest if desired.
Step‑by‑Step Instructions for Blueberry Lemon French Toast Casserole
Step 1: Prepare Cream Cheese Filling
In a mixing bowl, blend the cream cheese, powdered sugar, milk, and half of the vanilla extract until smooth and creamy, about 2-3 minutes. Gently fold in 1 cup of fresh blueberries, along with the lemon juice and zest. This delicious mixture will form a delightful filling that adds richness to your Blueberry Lemon French Toast Casserole.
Step 2: Layer Ingredients
Grease a 9×13-inch baking dish and layer half of the cubed French bread evenly across the bottom. Spoon the cream cheese mixture over the bread, ensuring an even distribution. Top with the remaining bread cubes, allowing the bread to soak up the creamy filling beneath. This layering creates a beautiful texture for your casserole.
Step 3: Create Egg Mixture
In a separate bowl, whisk together the eggs, milk, remaining vanilla extract, cinnamon, nutmeg, lemon zest, and lemon juice until thoroughly combined and slightly frothy. Carefully pour this egg mixture evenly over the layered bread, ensuring all the bread gets soaked. This crucial step will create a custard-like texture in the Blueberry Lemon French Toast Casserole.
Step 4: Chill Overnight
Cover the baking dish with aluminum foil and refrigerate for at least 8 hours, or overnight if possible. Chilling allows the flavors to meld and ensures the bread absorbs the creamy egg mixture fully. When morning arrives, you’ll have a casserole ready to bake, making your breakfast effortless.
Step 5: Bake
When you’re ready to bake, preheat your oven to 375°F (190°C). Let the casserole sit at room temperature for about 15 minutes while the oven heats. Bake the casserole covered with foil for 45 minutes, then remove the foil and continue baking for an additional 30 minutes, or until the top is golden brown and the edges are set. The warm aroma will fill your kitchen, making it impossible to resist!
Step 6: Serve and Enjoy
Remove the Blueberry Lemon French Toast Casserole from the oven and allow it to cool for about 10 minutes before serving. This resting time helps the casserole firm up for easier slicing. Serve warm with a drizzle of maple syrup, a dusting of powdered sugar, or a dollop of whipped cream, and enjoy a delightful breakfast that will have everyone asking for seconds!

Make Ahead Options
This Blueberry Lemon French Toast Casserole is perfect for meal prep! You can assemble the entire dish up to 24 hours in advance, allowing the bread to soak up the creamy filling overnight for maximum flavor. Simply complete steps 1 through 4, cover with foil, and refrigerate. For quality, ensure the casserole is well-covered to prevent any drying out. When it’s time to serve, preheat your oven to 375°F, let it sit at room temperature for about 15 minutes, then bake for about 75 minutes until golden brown. With this simple make-ahead plan, you’ll have a delicious breakfast ready with minimal morning effort!

Blueberry Lemon French Toast Casserole Recipe FAQs
What kind of blueberries should I use for this casserole?
Absolutely! You can use fresh or frozen blueberries in your Blueberry Lemon French Toast Casserole. I recommend avoiding thawed frozen blueberries, as they can make the filling soggy. If using frozen berries, just toss them straight in without thawing to ensure they maintain their shape and firmness.
How long can I store leftovers?
You can store your leftover casserole in an airtight container in the fridge for up to 4 days. Just make sure to seal it tightly to preserve its freshness and prevent any odors from impacting the flavor. It’s so convenient to have leftovers for busy mornings!
Can I freeze the casserole? What’s the best way to do that?
Definitely! You can freeze your Blueberry Lemon French Toast Casserole for up to 2 months. To do so, cut the casserole into individual portions, wrap each piece securely in plastic wrap, and place them in a freezer-safe bag. This way, you can easily reheat only what you need for breakfast.
What if my casserole is too soggy after baking?
If your casserole turns out too soggy, it’s likely that the egg mixture wasn’t evenly distributed, or perhaps the bread wasn’t allowed to soak long enough. For next time, ensure that every piece of bread is submerged in the egg mixture, and consider chilling it for a longer period, ideally overnight, to absorb all those delicious flavors fully.
Can I modify this recipe for dietary restrictions, like dairy allergies?
Very much! For a dairy-free version of the Blueberry Lemon French Toast Casserole, simply use dairy-free cream cheese, and opt for almond or oat milk instead of regular milk. Just ensure all your ingredients are dairy-free—take a moment to double-check labels. It’s a wonderful way to accommodate different dietary needs while still enjoying a delicious breakfast!
