Ingredients

Scale
  • 6 cups fresh or frozen blueberries (do not thaw if frozen)
  • 1/2 cup granulated sugar
  • 2 tablespoons all-purpose flour
  • 1 teaspoon lemon juice
  • 1/2 teaspoon ground cinnamon
  • 1 cup old-fashioned rolled oats
  • 1/2 cup all-purpose flour
  • 1/2 cup packed light brown sugar
  • 1/4 teaspoon salt
  • 1/2 cup (1 stick) unsalted butter, cold and cut into small pieces

  • Instructions

    1. Preheat your oven to 375 F (190 C). Lightly grease an 8×8 inch or 9×9 inch baking dish with butter or non-stick spray. This prevents the blueberry filling from sticking and makes for easier serving.

    2. In a large bowl, combine the fresh or frozen blueberries, granulated sugar, 2 tablespoons of all-purpose flour, lemon juice, and ground cinnamon. Stir gently until the blueberries are evenly coated. The flour helps to thicken the juices as the crisp bakes, creating a luscious filling.

    3. Pour the blueberry mixture into your prepared baking dish, spreading it out into an even layer. This ensures consistent cooking and a balanced ratio of fruit to topping in every bite.

    4. In a separate medium bowl, combine the old-fashioned rolled oats, 1/2 cup all-purpose flour, light brown sugar, and salt. Mix these dry ingredients together thoroughly.

    5. Add the cold, cubed butter to the dry oat mixture. Using your fingertips, a pastry blender, or two knives, cut the butter into the mixture until it resembles coarse crumbs with some pea-sized pieces remaining. Avoid overworking the mixture; the goal is a crumbly texture, not a smooth dough.

    6. Sprinkle the oat crumble topping evenly over the blueberry filling in the baking dish. Place the dish on a baking sheet (to catch any potential drips) and bake for 35-40 minutes, or until the blueberry filling is bubbly around the edges and the oat topping is golden brown and crisp.

    7. Once baked, remove the crisp from the oven and let it cool for at least 10-15 minutes before serving. This allows the filling to set slightly, preventing it from being too runny, and ensures the topping remains crisp.

    INGREDIENTS:

    • 6 cups fresh or frozen blueberries (do not thaw if frozen)
    • 1/2 cup granulated sugar
    • 2 tablespoons all-purpose flour
    • 1 teaspoon lemon juice
    • 1/2 teaspoon ground cinnamon
    • 1 cup old-fashioned rolled oats
    • 1/2 cup all-purpose flour
    • 1/2 cup packed light brown sugar
    • 1/4 teaspoon salt
    • 1/2 cup (1 stick) unsalted butter, cold and cut into small pieces

    For the blueberries, using fresh berries when they are in season will give you the best flavor, but frozen blueberries work perfectly well and are a great option for convenience. If using frozen, there’s no need to thaw them beforehand; they will cook down beautifully in the oven. The lemon juice is a small but mighty addition, brightening the flavor of the blueberries and preventing the filling from becoming too sweet.

    When it comes to the oat topping, old-fashioned rolled oats are preferred over instant oats as they provide a better texture and chewiness. For the butter, ensure it is cold and cut into small pieces; this is crucial for achieving that perfectly crumbly topping. If you prefer, you can use a plant-based butter alternative for a dairy-free version, or even coconut oil, though the flavor profile will shift slightly. Feel free to adjust the amount of cinnamon in the topping to your preference, or even add a pinch of nutmeg for extra warmth.

    Making this blueberry crisp is a simple process, broken down into easy-to-follow steps that ensure a delicious outcome every time.

    1. Prepare your baking dish and oven: Preheat your oven to 375°F (190°C). Lightly grease an 8×8 inch or 9×9 inch baking dish with butter or non-stick spray. This prevents the blueberry filling from sticking and makes for easier serving.
    2. Mix the blueberry filling: In a large bowl, combine the fresh or frozen blueberries, granulated sugar, 2 tablespoons of all-purpose flour, lemon juice, and ground cinnamon. Stir gently until the blueberries are evenly coated. The flour helps to thicken the juices as the crisp bakes, creating a luscious filling.
    3. Transfer filling to the dish: Pour the blueberry mixture into your prepared baking dish, spreading it out into an even layer. This ensures consistent cooking and a balanced ratio of fruit to topping in every bite.
    4. Prepare the oat crumble topping: In a separate medium bowl, combine the old-fashioned rolled oats, 1/2 cup all-purpose flour, light brown sugar, and salt. Mix these dry ingredients together thoroughly.
    5. Incorporate the butter into the topping: Add the cold, cubed butter to the dry oat mixture. Using your fingertips, a pastry blender, or two knives, cut the butter into the mixture until it resembles coarse crumbs with some pea-sized pieces remaining. Avoid overworking the mixture; the goal is a crumbly texture, not a smooth dough.
    6. Assemble and bake the crisp: Sprinkle the oat crumble topping evenly over the blueberry filling in the baking dish. Place the dish on a baking sheet (to catch any potential drips) and bake for 35-40 minutes, or until the blueberry filling is bubbly around the edges and the oat topping is golden brown and crisp.
    7. Cool before serving: Once baked, remove the crisp from the oven and let it cool for at least 10-15 minutes before serving. This allows the filling to set slightly, preventing it from being too runny, and ensures the topping remains crisp.

    Easy Variations And Serving Ideas That Fit Real Life

    This blueberry crisp is fantastic on its own, but it’s also incredibly adaptable to different tastes and occasions. For a fun twist, consider mixing in other berries with the blueberries, such as raspberries or blackberries, for a “mixed berry” crisp. A handful of chopped nuts like pecans or walnuts can be added to the oat topping for extra crunch and a nutty flavor. For a touch of citrus, you could add some orange zest to the blueberry filling along with the lemon juice.

    When serving, a warm scoop of vanilla bean ice cream is the classic accompaniment, creating a delightful contrast between hot and cold, creamy and crunchy. For a lighter option, a dollop of Greek yogurt or a drizzle of heavy cream can be just as satisfying. This crisp is also wonderful served with a simple custard sauce or even a sprinkle of powdered sugar. It’s perfect for a casual family dessert, but elegant enough to serve at a small dinner party. For a buffet, you can bake it in individual ramekins for easy portioning. Kids often love helping sprinkle the topping, making it a fun activity to involve them in the kitchen.

    Common Slip-Ups And How To Avoid Them

    Even simple recipes can have common pitfalls. One frequent mistake with fruit crisps is not allowing the filling to thicken properly. This often happens if you reduce the amount of flour in the fruit mixture or don’t bake it long enough. The flour is crucial for absorbing the fruit juices and creating a luscious, not watery, filling. Ensure the crisp bakes until the filling is visibly bubbling around the edges, indicating it’s hot enough to activate the thickening properties of the flour.

    Another common issue is an overly soft or greasy topping. This usually occurs if the butter isn’t cold enough or if the topping mixture is overworked. Cold butter creates steam as it bakes, which helps form those desirable crisp pockets. If the butter is too warm, it melts into the flour too quickly, leading to a dense, less crumbly texture. Use cold butter and work it into the dry ingredients just until coarse crumbs form, avoiding the temptation to knead it like dough. Also, make sure to spread the topping evenly; large clumps can prevent even baking and crisping. Finally, resist the urge to cut into the crisp immediately after removing it from the oven. Giving it 10-15 minutes to cool allows the filling to set, preventing it from spilling out when served.

    How To Store It And Make It Ahead Without Ruining Texture

    Storing your blueberry crisp properly will ensure it stays delicious for days, and making it ahead can be a real time-saver. Once cooled completely, cover any leftover crisp tightly with plastic wrap or aluminum foil and store it at room temperature for up to 2 days. If you live in a warm or humid climate, or if you want to extend its freshness, you can store it in the refrigerator for up to 4-5 days.

    To reheat, you can warm individual portions in the microwave for 30-60 seconds, though the topping might lose some of its crispness. For best results and to restore the topping’s crunch, reheat the entire crisp (or larger portions) in a preheated oven at 350°F (175°C) for 15-20 minutes, or until warmed through and the topping is crisp again. If the topping starts to brown too much, you can loosely tent it with foil.

    For making ahead, you have a couple of options. You can assemble the entire crisp (fruit filling and topping)
