Ingredients for Blueberry Crisp

This recipe uses simple pantry staples and fresh (or frozen) blueberries to create a dessert that feels indulgent without being fussy.

For the Blueberry Filling:

• 6 cups fresh or frozen blueberries

• 2 tablespoons cornstarch (or arrowroot powder)

• 1/3 cup granulated sugar (adjust based on berry sweetness)

• 1 tablespoon lemon juice

• 1 teaspoon lemon zest

• 1 teaspoon pure vanilla extract

• Pinch of salt

For the Crisp Topping:

• 1 cup old-fashioned rolled oats

• 3/4 cup all-purpose flour (or almond flour for a gluten-free version)

• 1/2 cup brown sugar, packed

• 1/2 teaspoon ground cinnamon

• 1/4 teaspoon salt

• 1/2 cup (1 stick) unsalted butter, cold and cut into cubes (or coconut oil for vegan)

Step-by-Step Instructions

1. Preheat the Oven

Start by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish or a 2-quart casserole dish with butter or nonstick spray.

2. Prepare the Blueberry Filling

In a large mixing bowl, combine the blueberries with the sugar, cornstarch, lemon juice, lemon zest, vanilla extract, and a pinch of salt. Toss everything together until the blueberries are evenly coated.

Pro Tip: If using frozen blueberries, do not thaw them first — this helps prevent excess moisture in the filling.

Transfer the mixture into your prepared baking dish and spread it out evenly.

3. Make the Crisp Topping

In a separate bowl, stir together the oats, flour, brown sugar, cinnamon, and salt. Add the cold butter and use a pastry cutter, fork, or your fingers to mix until the topping resembles coarse crumbs.

Optional Add-In: For extra crunch, stir in 1/3 cup chopped nuts such as pecans or almonds.

4. Assemble and Bake

Sprinkle the crisp topping evenly over the blueberry mixture. Don’t press it down — the loose crumble texture is what creates that irresistible crispy top.

Bake in the preheated oven for 35–45 minutes, or until the topping is golden brown and the blueberries are bubbling around the edges.

5. Cool and Serve

Let the crisp cool for at least 10–15 minutes before serving. This gives the filling time to thicken slightly, making for a better texture.

Serve warm, topped with a generous scoop of vanilla ice cream, a dollop of whipped cream, or a drizzle of heavy cream.

Blueberry Crisp Variations

The beauty of this recipe lies in its flexibility. Here are a few delicious ways to make it your own:

Mixed Berry Crisp

Replace some of the blueberries with raspberries, blackberries, or strawberries for a mixed berry version that’s even more colorful and flavorful.

Apple-Blueberry Crisp

Add two peeled, chopped apples to the filling for an extra layer of sweetness and texture.

Gluten-Free Version

Use almond flour or a certified gluten-free flour blend in place of all-purpose flour. Make sure your oats are labeled gluten-free.

Vegan and Dairy-Free Option

Swap butter with coconut oil or a vegan butter alternative. Use plant-based ice cream or yogurt for serving.

Maple Sweetened Crisp

Replace the granulated and brown sugar with maple syrup or honey (about 1/4 cup in the filling, and 1/3 cup in the topping) for a naturally sweetened option.

Tips for the Best Blueberry Crisp

• Use Fresh, Ripe Berries: For the best flavor, use blueberries that are sweet and juicy. However, high-quality frozen berries also work well — just skip thawing.

• Taste and Adjust Sweetness: Blueberries can vary in sweetness. Taste a few before mixing the filling and adjust sugar accordingly.

• Cold Butter Is Key: Keeping the butter cold when making the topping helps create a crumbly, crisp texture.

• Don’t Overbake: Bake until the top is golden and the filling is bubbling, but avoid overbaking, which can dry out the topping.

Make-Ahead and Storage Tips

Make-Ahead:

• Assemble Ahead: You can assemble the crisp up to 1 day in advance. Store covered in the refrigerator until ready to bake.

• Freezer-Friendly: Prepare and freeze before baking. Wrap tightly and freeze for up to 3 months. Bake directly from frozen, adding an extra 10–15 minutes to the baking time.

Storage:

• Refrigerator: Leftovers can be stored in the fridge for up to 5 days. Reheat in the oven at 350°F until warm and crisp again.

• Freezer: Freeze baked blueberry crisp for up to 2 months. Reheat in the oven for best texture.

Serving Suggestions

Blueberry Crisp is delicious on its own, but here are a few ways to take it to the next level:

• Classic: A scoop of vanilla ice cream melting into the warm crisp.

• Light and Fresh: A dollop of whipped cream or Greek yogurt.

• Brunch-Ready: Serve with crème fraîche and a side of bacon or sausage for a sweet-savory combo.

• Elegant Dessert: Top with lemon zest or a sprinkle of toasted almonds.

Frequently Asked Questions

Can I use frozen blueberries?

Yes. No need to thaw them — just toss them with the other filling ingredients and bake as directed.

Can I reduce the sugar in this recipe?

Absolutely. Feel free to cut back on the sugar if your berries are naturally sweet or if you prefer a tarter dessert. You can also use natural sweeteners like maple syrup or coconut sugar.

What’s the difference between a crisp and a crumble?

Both desserts feature fruit with a streusel-like topping, but crisps typically include oats, which give them a crunchier texture. Crumbles, on the other hand, usually rely solely on flour, butter, and sugar for a softer topping.

Can I double the recipe for a crowd?

Yes — simply double the ingredients and bake in a larger 9×13-inch pan. You may need to extend the baking time slightly.

Can I make individual servings?

Absolutely. Divide the filling and topping into ramekins and bake for 25–30 minutes.
