Step-by-Step Instructions
Step 1: Prepare Your Baking Dish
Generously grease a 9×13-inch baking dish with butter. This ensures your baked blueberry breakfast won’t stick and makes cleanup easier. Pro tip: If you have a ceramic or glass baking dish, use it for more even heat distribution.
Step 2: Arrange Bread and Blueberries
Spread half the bread cubes in the prepared baking dish. Scatter 1 cup of blueberries evenly over the bread. Top with remaining bread cubes and the other cup of blueberries, gently pressing down to create a relatively even surface.
Step 3: Create the Custard Mixture
In a large bowl, whisk together eggs, milk, cream, sugar, vanilla, cinnamon, nutmeg, salt, and lemon zest (if using) until well combined. The custard should be smooth and evenly spiced. For extra flavor depth, warm your milk and infuse it with a cinnamon stick before cooling and adding to the mixture.
Step 4: Pour and Soak
Pour the custard mixture evenly over the bread and blueberries, ensuring all pieces get saturated. Press down gently with a spatula to help the bread absorb the liquid. Cover with plastic wrap and refrigerate for at least 8 hours or overnight (up to 24 hours).
Step 5: Prepare the Streusel Topping
In a medium bowl, combine flour, brown sugar, cinnamon, and salt. Using a pastry cutter or your fingers, work the cold butter into the mixture until it resembles coarse crumbs. Refrigerate the streusel until ready to bake.
Step 6: Baking Preparation
When ready to bake, preheat your oven to 350°F (175°C). Remove the baking dish from the refrigerator and let it sit at room temperature for about 30 minutes while your oven preheats. Remove the plastic wrap and sprinkle the streusel topping evenly over the soaked bread mixture.
Step 7: Bake to Golden Perfection
Bake in the preheated oven for 45-55 minutes until the center is set and the top is golden brown. Insert a knife in the center – it should come out clean but moist. If the top browns too quickly, cover with foil during the last 15 minutes of baking.
Step 8: Rest and Serve
Allow the Overnight Blueberry French Toast to rest for 10 minutes before serving. This resting period allows the flavors to settle and makes serving easier. Dust with powdered sugar, add fresh blueberries, and drizzle with warm maple syrup.

- Substitute half the eggs with egg whites to reduce cholesterol
- Replace sugar with monk fruit sweetener or maple syrup for a less processed option
- Add chia seeds or ground flaxseed for omega-3 fatty acids and additional fiber
- Increase the berry-to-bread ratio for more antioxidants and natural sweetness
Serving Suggestions
- Create a breakfast buffet by pairing with a savory egg casserole for balance
- Serve with a side of Greek yogurt drizzled with honey for added protein
- For brunch gatherings, complement with a fresh fruit platter and sparkling mimosas
- During winter months, pair with warm spiced apple cider for a cozy experience
- For summer brunches, serve with a refreshing berry lemonade
Common Mistakes to Avoid
- Using Fresh Bread: Fresh bread doesn’t absorb the custard properly. Data shows day-old or slightly dried bread absorbs 30% more liquid.
- Skipping the Soaking Time: Rushing the overnight soak means uneven absorption. At least 8 hours creates the perfect texture.
- Overcrowding Blueberries: Too many berries release excessive moisture. Stick to the recommended amount for the perfect balance.
- Opening the Oven Frequently: Each opening drops oven temperature by about 25°F, extending cooking time and affecting rise.
- Serving Immediately: Not allowing a 10-minute rest means your casserole might fall apart when served.
Storing Tips for the Recipe
- Refrigerate Leftovers: Store in an airtight container for up to 3 days.
- Freezing Option: Portion and freeze for up to 2 months. Thaw overnight in the refrigerator.
- Reheating Method: Warm individual portions in the microwave for 60-90 seconds or in a 350°F oven for 10-15 minutes until heated through.
- Make-Ahead Streusel: The streusel topping can be made up to 3 days ahead and stored in the refrigerator.

FAQs
Can I use frozen blueberries instead of fresh?
Yes! Use frozen berries directly from the freezer without thawing. This prevents the color from bleeding too much into the custard.
Can this recipe be made dairy-free?
Absolutely. Substitute almond milk for regular milk, coconut cream for heavy cream, and use a plant-based butter alternative in the streusel topping.
What’s the best bread to use for this recipe?
Challah, brioche, or sourdough work best because of their structure and ability to absorb the custard without falling apart.
Can I prepare this more than one night ahead?
Yes, you can assemble it up to 24 hours in advance. The streusel should be added just before baking.
Why is my French toast soggy in the middle?
This typically happens if the bread-to-custard ratio is off. Ensure you’re using a full 16oz loaf of bread and that your baking dish is the correct size.
