Ingredients
Gather your simple ingredients to create this fantastic Blueberry French Toast Casserole. You will need a dense bread, fresh or frozen blueberries, and common pantry staples. The streusel topping adds an irresistible crunch that sets this dish apart.
- 1 (12–14-ounce/340–400g) loaf French bread, sourdough bread, brioche, or challah
- 1 cup (140g) fresh or frozen blueberries
- 8 large eggs
- 2 and 1/4 cups (540ml) whole milk
- 1/2 teaspoon ground cinnamon
- 3/4 cup (150g) packed light brown sugar
- 1 Tablespoon (15ml) pure vanilla extract
- 1/3 cup (69g) packed light or dark brown sugar (for streusel)
- 1/3 cup (41g) all-purpose flour (spooned & leveled) (for streusel)
- 1/2 teaspoon ground cinnamon (for streusel)
- 6 Tablespoons (85g) unsalted butter, cold and cubed (for streusel)
- Optional toppings: extra blueberries, maple syrup, and/or confectioners’ sugar for topping
Notes & Substitutions
- Bread Choice: For the best results, use a dense, day-old bread like French bread, sourdough, brioche, or challah. Culinary experts often recommend using day-old bread for dishes like French toast and bread pudding because its drier texture allows for better absorption of liquids. Stale bread absorbs the custard better, preventing a soggy casserole.
- Staling Shortcut: If using fresh bread, cut it into cubes and spread on a baking sheet. Bake at 250°F (120°C) for 10-15 minutes until slightly dry, then cool completely.
- Blueberries: Fresh or frozen blueberries work wonderfully here. There is no need to thaw frozen blueberries; simply add them straight to the pan.
- Other Berries/Fruit: Feel free to swap blueberries for raspberries, sliced strawberries, cranberries, or even thinly sliced apples for a seasonal twist.
- Milk: Whole milk creates the richest custard, but 2% milk works too. For dairy-free, oat milk can be substituted, though the final texture may vary slightly.
- Streusel: Always use cold butter for the streusel. This ensures a crumbly texture and prevents it from melting too quickly.
Equipment
You only need a few basic kitchen tools to prepare this delightful overnight French toast bake.
- 9×13 inch baking dish
- Large mixing bowls (2-3)
- Whisk or electric mixer
- Pastry blender (for streusel)
- Measuring cups and spoons
Instructions
Creating this delicious Blueberry French Toast Casserole is straightforward, even for beginners. Follow these steps for a perfect make-ahead breakfast or brunch. The key to success is allowing the bread ample time to soak up the creamy custard.
Step 1: Prepare Baking Dish & Bread
First, grease a 9×13-inch pan thoroughly with butter or nonstick spray. This prevents sticking and ensures easy removal. Next, slice your chosen bread, then cut it into 1-inch cubes. Spread these bread cubes evenly across the bottom of the prepared baking pan. Finally, scatter the blueberries evenly over the bread layer.
Step 2: Make & Pour Custard
In a large mixing bowl, whisk together the eggs, milk, ground cinnamon, brown sugar, and vanilla extract. Continue whisking until the brown sugar is fully dissolved and the mixture is smooth, with no lumps remaining. Slowly and evenly pour this delicious custard mixture over the bread and blueberries in the pan. Gently press down any floating bread pieces to ensure they are well-coated and submerged in the custard.
Step 3: Chill Overnight
Cover the baking dish tightly with plastic wrap or aluminum foil. Refrigerate the casserole for a minimum of 3 hours, but ideally, let it chill overnight (up to 24 hours). This crucial chilling time allows the bread to fully absorb the custard, leading to a richer flavor and a perfectly tender, custardy texture after baking. Do not skip this step for the best results.
Step 4: Prepare Streusel Topping
When you are ready to bake, begin preparing the streusel topping. In a medium bowl, whisk together the brown sugar, all-purpose flour, and cinnamon until well combined. Add the cold, cubed unsalted butter to the dry ingredients. Use a pastry blender or your fingertips to cut the butter into the flour mixture. Work quickly until the mixture resembles coarse crumbs, with some pea-sized pieces of butter remaining. This texture will create a wonderfully crisp topping.
Step 5: Bake the Casserole
Preheat your oven to 350°F (177°C). Remove the covered casserole dish from the refrigerator. Remove the plastic wrap or foil. Evenly sprinkle the prepared streusel topping over the entire surface of the soaked bread and blueberries. Place the casserole in the preheated oven and bake for 45–55 minutes. According to USDA guidelines, cooking egg-based casseroles to 160°F (71°C) ensures food safety. The casserole is done when the streusel is golden brown and crisp, and the custard is set, with an internal temperature reaching 160°F (71°C). I often bake for 45 minutes for a softer center.
Step 6: Serve Warm
Once baked, remove the Blueberry French Toast Casserole from the oven. Let it cool slightly for about 5-10 minutes before serving. This brief cooling time helps the casserole set further, making it easier to portion. Serve warm with your favorite toppings.
Pro Tips & Troubleshooting
- Preventing Soggy Casserole: Always use dense, day-old bread, as it absorbs the custard without becoming mushy. Avoid over-soaking the bread in custard; overnight is perfect, but don’t go past 24 hours.
- Achieving Crisp Streusel: Add the streusel topping just before baking, not the night before. This keeps it from absorbing moisture and ensures maximum crunch.
- Even Baking: For a consistently golden-brown finish, rotate the baking pan halfway through the cooking time. This helps prevent hot spots in your oven.
- Adjusting Sweetness: The recipe offers a balanced sweetness. If you prefer it less sweet, slightly reduce the brown sugar in both the custard and streusel.
- Golden Brown Top: If the streusel is browning too quickly before the casserole is cooked through, lightly tent the dish with aluminum foil. This protects the top while the inside finishes baking.
Serving, Storage & Variations
This Blueberry French Toast Casserole is incredibly versatile for serving and easy to manage for storage.
Serving Suggestions
- Drizzle generously with warm maple syrup for classic sweetness.
- Dollop with fresh whipped cream or a scoop of vanilla ice cream for a decadent treat.
- Garnish with extra fresh blueberries or a mix of seasonal berries.
- Pair it with a side of crispy bacon, savory sausage, or a light fruit salad for a complete brunch spread.
- A dusting of confectioners’ sugar adds a beautiful finishing touch.
Storage
- Refrigerate: Store leftover Blueberry French Toast Casserole tightly covered in the refrigerator for 2-3 days.
- Reheating: Reheat individual portions in the microwave until warm. For larger amounts, warm in an oven preheated to 300°F (150°C) until heated through.
Freezing Instructions
- Unbaked: Assemble the casserole as directed, but do not add the streusel. Cover tightly with plastic wrap, then foil, and freeze for up to 1 month. Thaw in the refrigerator overnight before adding streusel and baking.
- Baked: Once completely cooled, cut the casserole into individual servings. Wrap each piece tightly in plastic wrap, then foil, and freeze for up to 1 month. Reheat from frozen in the microwave or oven.
Variations
- Mixed Berry: Use a delightful combination of raspberries, blackberries, and strawberries along with the blueberries.
- Cream Cheese Swirl: Beat 4 ounces softened cream cheese with 1/4 cup sugar and an egg yolk. Dollop and swirl into the custard before chilling.
- Lemon Zest: Add 1 tablespoon of fresh lemon zest to the custard mixture to brighten the blueberry flavor.
- Nutty: Stir 1/2 cup of chopped pecans or walnuts into the streusel topping for added crunch and flavor.
