Servings: 8 servings



  • 4 cups fresh blueberries - (frozen works too)
  • 3 tablespoons granulated sugar
  • 1 tablespoon + 1 teaspoon cornstarch
  • 3 teaspoons fresh lemon juice

Crumble topping

  • 3/4 cup all purpose flour
  • 3/4 (heaping) cup old fashioned rolled oats
  • 1/3 cup + 1 Tablespoon packed brown sugar
  • 1/4 teaspoon kosher salt
  • 1/4 teaspoon ground cinnamon
  • 1/2 cup butter, cold and cubed - (1 stick of butter)


  • Preheat the oven to 375°F. Spray or butter a 9"x6" inch pan. Set aside.
  • In a large bowl combine the blueberries, sugar, cornstarch, and lemon juice. Mix to combine. 
  • Place the blueberry mixture into the prepared baking pan. Spread into an even layer. Set aside.
  • In a medium size bowl add the flour, oats, brown sugar, sat, and cinnamon. Whisk to combine. 
  • Add the cold cubed butter. Using a pastry blender, cut the butter into the mixture until the butter is a tad larger than the size of peas. 
  • Evenly sprinkle the crumble mixture over the blueberries. Bake for 35-40 minutes, or until the crumble is golden brown and the blueberry juices are bubbling. 
  • Remove and let cool for 5-10 minutes. Serve warm with ice cream!


Blueberries: You can use fresh or frozen berries for this recipe. If using frozen, you do not need to thaw them prior to use. If using fresh, thoroughly wash them prior to using. 
Pastry blender: If you do not have a pastry blender that’s OK! You can use a fork to cut the butter into the flour mixture or use your hands. You can also freeze the butter and use a cheese grater and grate it into the mixture if you don’t have a pastry blender. 
Freezing: You can freeze the blueberry crisp prior to baking. Wrap it in plastic wrap and foil and store in the freezer for up to 3 months. Bake from frozen at 375 °F for 50-60 minutes. 
Storing: The blueberry crisp will last for 4-5 days in the fridge. Store covered or in an airtight container. The crumble topping will most likely soften with time, but it still tastes delicious!
