This easy blueberry crumble recipe is bursting with fresh blueberry flavor! (You’ll love the crispy crumble topping.) 



For The Blueberry Filling:

  • 6 cups fresh blueberries, washed and dried
  • 1/3 cup sugar
  • 2 teaspoons lemon zest 
  • 1 Tablespoon fresh lemon juice
  • 2 Tablespoons cornstarch
  • pinch salt

For The Crumble Topping:


  1. Preheat The Oven & Prep Your Pan. Start by pre-heating the oven to 350 degrees F. Set out an 8×8″ or 9×9″ square baking dish.
  2. Start The Blueberry Filling. In a large bowl, combine fresh blueberries, sugar, lemon zest, lemon juice, cornstarch, and salt. Stir to coat the berries well. (You want the cornstarch really evenly distributed)
  3. Pour The Filling Into Your Baking Dish and set aside.
  4. Next, Start The Crumble Topping. Using the same large bowl (yay for saving dishes!), combine cubed butter, brown sugar, gluten-free flour, oats, vanilla, and salt.
  5. Mix Until Crumble Forms. Using a fork, pastry blender (or your hands–my favorite!), work the butter into the dry ingredients until clusters form and the dry ingredients and butter are well combined.
  6. Sprinkle Crumble Over The Blueberry Filling. Distribute the crumble clusters over the blueberry filling. I like to try for a variety of sizes and shapes–some larger pieces mixed with some smaller pieces.
  7. Bake The Crisp. Put the blueberry crisp in the oven and bake at 350 degrees for 40-50 minutes, or until the filling is bubbling and the crisp topping is golden. (If your crisp happens to brown quicker than you expect, feel free to cover the pan loosely with foil.)
  8. Cool A Bit Before Serving. Remove from the oven and cool 20-30 minutes before serving, if possible, to allow the filling to set. (It’ll be more liquid when piping hot, but it’ll set and thicken as it cools.) Serve with vanilla or lemon ice cream for best results! 


Can You Use Frozen Blueberries To Make Blueberry Crisp? Yes! The ice crystals on the frozen berries will make the filling a bit more liquid, so you can offset this by adding 1/2 Tbsp. more cornstarch to the filling or baking a bit longer to allow the filling more time to thicken.
