Mixed Berry Crisp Pie

I can’t think of a better way to eat berries. This crisp pie is topped with a oatmeal crumble that makes it irresistible.

Ingredients (for a 9” pie)

  • 6 cups frozen mixed berries (blueberries, blackberries, and raspberries)
  • 1 cup sugar
  • ¼ cup cornstarch
  • 2 tbsp lemon juice
  • 1 tsp vanilla extract
  • 9 in deep dish pie crust

Oatmeal Crumble Topping

  • 1 cup old-fashioned oats
  • ¾ cup brown sugar
  • ½ cup all purpose flour
  • 1 tsp cinnamon
  • 9 tbsp salted butter


Create the Oatmeal Crumble Topping

  1. Preheat oven to 400 degrees
  2. Cut 9 tbsp of salted butter into slices.
  3. In a separate mixing bowl, combine 1 cup old-fashioned oats, ¾ cup brown sugar, 1 tsp cinnamon, ½ cup all purpose flour, and butter slices. Mix with a pastry blender until pea sized clumps form. Set aside and work on filling. 


  1. Completely thaw 6 cups of frozen mixed berries. Drain any excess liquid.
  2. .In a large mixing bowl, mix berries, 1 cup sugar, ¼ cup cornstarch, 2 tbsp lemon juice and 1 tsp vanilla. Toss until evenly coated. 
  3. Pour berry filling into a 9 inch pie crust. Pour berry mixture into a 9 inch deep dish pie crust.

Assembly and Bake

  1. Sprinkle oatmeal crumble topping evenly over the mixed berries until completely covered.
  2. Bake for 30 minutes.
  3. Reduce oven temperature to 350 and bake for an additional 15-20 minutes.
  4. Cool for 2 hours at room temperature before serving. 


*It is important to drain any excess liquid from the frozen berries.

**Resist the temptation to cut into this pie immediately. It is important not to skip cooling for 2 hours. Cooling it allows the filling to thicken.
