I’ve never met a fruit crumble I haven’t liked, whether it’s apple crumble in the fall or strawberry-rhubarb in the spring. Come summer, however, I only want to eat blueberry crumble on repeat.
Here, the slightest hint of citrusy, bright, and earthy ground coriander in the filling turns this particular blueberry crumble into something truly spectacular. Coriander is a surprising yet natural match for blueberries, enhancing both flavor and sweetness and resulting in better-tasting berries.
As the crumble bakes, the berries transform into a sweet-tart, jammy delight that’s offset by the crunchy streusel. Finishing with a scoop of vanilla ice cream on top is, in my opinion, non-negotiable.
What Is Blueberry Crumble Made Of?
Like most fruit crumbles, the ingredients you need are, for the most part, pantry staples you already have on hand. The addition of ground coriander, however, makes this particular blueberry crumble stand out among the rest.
- Fresh or frozen blueberries
- Granulated sugar
- Cornstarch
- Vanilla extract
- Ground coriander
- Unsalted butter
- Lemon
- All-purpose flour
- Light or dark brown sugar
- Baking powder
- Sliced almonds (optional)
What’s the Difference Between a Crumble and a Crisp?
The difference between fruit crumble and crisp has gotten less distinct over the years. Generally speaking, both are baked fruit desserts with a streusel-like topping. The topping for crumbles traditionally doesn’t contain oats, while the topping for a crisp does, however the lines have blurred over time.
This crumble stays true to the traditional definition and doesn’t contain oats in the topping. It does, however, contain optional sliced almonds for added crunch.
Can I Use Frozen Blueberries?
Yes! While nothing beats fresh blueberries, their season is short. When summer is over, feel free to make this crumble with regular (not wild) frozen blueberries.
You’ll just want to thaw them before using. Our favorite way to do this is to spread the frozen blueberries out in a single layer on a baking sheet and let them sit at room temperature until thawed, which will take about an hour.

- 1/2 cup
packed light or dark brown sugar
- 1 teaspoon
baking powder
- 1/4 teaspoon
kosher salt
- 1/4 cup
sliced almonds (optional)
For the filling:
- 5 cups
fresh or frozen blueberries (2 pints or about 24 ounces)
- 1/2 cup
granulated sugar
- 1/4 cup
cornstarch
- 1/2 teaspoon
ground coriander
- 1/2 teaspoon
kosher salt

Vanilla ice cream, for serving (optional)
Instructions
If using frozen blueberries, thaw 5 cups (about 24 ounces). Cut 1 stick unsalted butter into a few large pieces and let sit at room temperature until softened.
Arrange a rack in the middle of the oven and heat the oven to 375°F. Coat an 8- or 9-inch square or other 2- to 2 1/2-quart baking dish with butter.
Make the crumble topping:
Finely grate the zest of 1/2 small lemon into a medium bowl (about 1 teaspoon); reserve the zested lemon for the filling. Add 1 cup all-purpose flour, 1/2 cup packed light or dark brown sugar, 1 teaspoon baking powder, and 1/4 teaspoon kosher salt, and whisk to combine.
Add the butter and toss and work with your fingers into the dry ingredients until large, heavy crumbles are formed and no loose flour remains.
Make the filling:
Drain the liquid from the thawed frozen blueberries.
Place 1/2 cup granulated sugar, 1/4 cup cornstarch, 1/2 teaspoon ground coriander, and 1/2 teaspoon kosher salt in the baking dish and whisk to combine and break up any lumps.
Add the blueberries and 1 teaspoon vanilla extract. Juice the zested lemon until you have 1 tablespoon juice, then add to the baking dish. Toss gently to combine, then spread into an even layer.
Break the crumble topping into large clumps with your fingers and arrange over the filling in an even layer. Sprinkle with 1/4 cup sliced almonds if using.
Bake until the crumble topping is golden-brown and the filling is bubbling, 30 to 35 minutes. Let cool for at least 15 minutes before serving. Top with vanilla ice cream if desired.
