This Blueberry French Toast Casserole is a yummy breakfast treat that combines fluffy bread, sweet blueberries, and creamy custard. Perfect for a crowd or just a special weekend brunch!
I love how you can prepare it the night before! Just pop it in the oven in the morning and enjoy the delicious smell wafting through the house. It’s almost like magic! 🍞✨
Key Ingredients & Substitutions
Bread: Brioche or challah adds a rich flavor and soft texture. If you’re looking for alternatives, use any thick bread like French or Texas toast. Just keep in mind that sturdier bread holds up better in the custard.
Blueberries: Fresh blueberries bring natural sweetness and juicy bursts. You can swap with frozen blueberries if you can’t find fresh, but don’t defrost them; add them straight from the freezer to avoid sogginess.
Eggs: Key for the custard texture. If you need an egg substitute for dietary reasons, try using 1/4 cup of unsweetened applesauce or a flaxseed egg (1 tablespoon flaxseed meal with 2.5 tablespoons water) per egg. The texture may vary slightly.
Cream Cheese: It adds a lovely creaminess. If you want a dairy-free option, try using plant-based cream cheese or simply skip it for a lighter version.
How Do I Make Sure My Casserole is Fluffy and Delicious?
To achieve the perfect texture, it’s crucial to let the bread soak in the custard overnight. This ensures every bite is moist and flavorful. Here’s a step-by-step:
- After mixing the custard, pour it over the bread cubes and gently press down. This helps the bread absorb the liquid.
- Cover it and refrigerate! Overnight soaking is best, but if you’re short on time, aim for at least 4 hours.
- Before baking, let it sit at room temperature for about 15 minutes. This prevents temperature shock and helps it bake evenly.
Finally, remember to bake until it’s golden on top for that ideal fluffy center. Enjoy your bake!
Blueberry French Toast Casserole
Ingredients You’ll Need:
For the Base:
- 1 loaf brioche or challah bread, cut into 1-inch cubes (about 8 cups)
- 2 cups fresh blueberries (plus extra for garnish)
For the Custard:
- 8 large eggs
- 2 cups whole milk
- 1/2 cup granulated sugar
- 1/4 cup brown sugar
- 2 teaspoons pure vanilla extract
- 1 teaspoon ground cinnamon
- 1/4 teaspoon salt
For Extra Creaminess (Optional):
- 4 oz cream cheese, cut into small cubes
For Serving:

How Much Time Will You Need?
This delicious casserole requires about 15 minutes of prep time and then you’ll need to let it sit for at least 4 hours (or ideally overnight) in the fridge. On baking day, it takes about 45-50 minutes in the oven. So, set aside some time the night before for the best results!
Step-by-Step Instructions:
1. Prepare Your Baking Dish:
Start by greasing a 9×13 inch baking dish with butter or non-stick spray. This helps to keep your casserole from sticking!
2. Assemble the Base:
Spread the cubed bread evenly in the greased dish. If you’re using cream cheese, sprinkle the cubes evenly over the bread, and then add the fresh blueberries on top.
3. Make the Custard Mixture:
In a large bowl, whisk together the eggs, milk, granulated sugar, brown sugar, vanilla, cinnamon, and salt until everything is well combined. This mixture is going to soak into the bread and make it delicious!
4. Combine Everything:
Pour the custard mixture evenly over the bread cubes. Use a spatula or your hands to gently press down the bread to ensure it soaks up the egg mixture.
5. Chill the Casserole:
Cover the casserole tightly with plastic wrap and place it in the refrigerator for at least 4 hours (or overnight!). This will help the flavors develop and the bread absorb the custard.
6. Preheat the Oven:
The next morning, preheat your oven to 350°F (175°C) while you prepare to bake!
7. Ready to Bake:
Take the casserole out of the fridge and let it sit at room temperature for about 15 minutes before baking. This helps it to bake more evenly.
8. Bake the Casserole:
Bake the casserole uncovered for 45-50 minutes, or until the custard is set and the top is golden brown. Your kitchen will smell amazing!
9. Finishing Touches:
Once baked, remove the casserole from the oven and let it cool slightly. Then, dust it generously with powdered sugar.
10. Serve and Enjoy:
Garnish with extra blueberries and fresh mint leaves if desired. Serve warm with maple syrup on the side. Dig in and enjoy your fluffy, creamy, and fruity breakfast treat!
Can I Use Frozen Blueberries Instead of Fresh?
Absolutely! Frozen blueberries work great in this casserole. Just add them straight from the freezer, and there’s no need to thaw them first to prevent excessive moisture.
How Do I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm individual portions in the microwave or in the oven set to low until heated through.
Can I Prep This Casserole the Night Before?
Yes! In fact, it’s recommended to let it soak overnight so the bread absorbs the custard fully. Just prepare it up to the baking step, cover tightly, and refrigerate until you’re ready to bake.
What Other Types of Bread Can I Use?
You can substitute brioche or challah with other types of bread like Texas toast or thick slices of sourdough. Just make sure the bread is sturdy enough to hold up to the custard!
