Easy Blueberry Crumble Recipe (Use Fresh or Frozen!)

Sharing is caring!

I love the summer season because that always means it’s blueberry season! We grow our own here, which sounds like a lot more work than it really is. We have several blueberry bushes, but one in particular produces buckets of juicy blueberries each summer, so I’m always looking for new ways to use them. 

This recipe is similar to my Fresh Raspberry Crumble and can be made with either fresh blueberries or frozen blueberries, and comes together in minutes. If you’ve been wary of fruit desserts (because chocolate is kind of hard to beat), then this is the perfect dessert. From the juicy blueberry filling to the tender crumble topping, this is sure to be a family favorite. 

What is a Fruit Crumble?

There are blueberry crisps, crumbles, and blueberry cobblers out there, but what’s the difference exactly? A fruit crumble is a dessert made with a layer of fruit, usually apples, berries, or stone fruits, topped with a crumbly mixture of butter, flour, sugar, and sometimes oats or nuts. (If you’re looking for a cobbler, check out my Whole Grain Skillet Peach Cobbler.)

The fruit is usually sweetened before being baked with the crumbly topping until it’s golden and crisp. For a consistent crumble topping, always use cold butter, just like you would for a pie crust. This easy recipe is commonly served warm, sometimes with a scoop of vanilla ice cream or a dollop of whipped cream.

  1. Begin by washing your fresh or frozen berries and letting them dry for just a few minutes. If your blueberries are fresh, you can place them on a clean kitchen towel to dry. If they are frozen, simply leave them in a colander for a few minutes. 
  2. Preheat oven to 350 degrees. Place clean blueberries in a bowl and add cornstarch and granulated sugar. Stir to combine. Pour berries into prepared baking dish. 
  1. In the same bowl (I’m all about reusing a bowl), whisk together the dry ingredients that are left: oats, flour, brown sugar, and cinnamon. 
  2. Using a pastry cutter or your hands, cut in cold butter until the mixture resembles coarse crumbles. (You could also use the food processor here, but note that your oatmeal will be less distinguishable.) 
  3. Spread crumble on top of the blueberries, making sure it covers them as much as possible. Place pan in the preheated oven.
  1. Bake for 40-45 minutes or until top is golden brown. 
  2. Serve warm with whipped cream or vanilla ice cream. 

How to Store Blueberry Crumble Leftovers

If you happen to have some blueberry crumble leftover, no worries. This easy fruit dessert can be stored in the fridge for 4-5 days in an airtight container. 

If your 8×8 pan doesn’t have a lid that came with it, try these silicone lids that sit on top and seal in. I love them for their ease of use! 

Substitutions and Additions for Fresh Blueberry Crumble

Don’t have exactly the ingredients I listed above or are you looking to add a bit of a different flavor to your fruit dessert next time? Here are some substitutions you can use!

  • Substitute blueberries alone for a mixed bag of berries from the frozen fruit section or use a mixture of fresh berries. 
  • Add lemon zest to the blueberry mixture for a tart, citrus zing to your blueberry crumble. 
  • Add extra cups of blueberries if you prefer a higher fruit to crumble ratio.
  • Swap the all-purpose flour for whole wheat for added nutrition
