Hello May! This is the perfect time to make Strawberry Rhubarb Crumble Pie using fresh and local Ontario field strawberries and Ontario rhubarb! Did you know, Ontario field strawberries are in season this month and rhubarb is in season until June? Combine these two fresh Ontario fruits and the goodness of Ontario oats to get a tasty spring dessert! 

Yield: 8 servings (1 pie)

Prep time: 30 minutes

Cook time: 50 minutes



  • 1 ½ cups rhubarb, chopped into 1-inch pieces 
  • 4 cups strawberries, hulled and quartered 
  • 1 lemon, juiced 
  • ½ cup granulated sugar 
  • 3 tbsp cornstarch 
  • Pinch of salt  


  • ¾ cup all-purpose flour 
  • ½ cup brown sugar, packed 
  • 2 tbsp granulated sugar 
  • ½ tsp baking powder 
  • Pinch of salt 
  • ½ cup unsalted butter, cut into ½-inch cubes 
  • ¾ cup rolled oats 

You will also need 1 pie crust – store bought or homemade! We like this homemade one from Sally’s Baking Addiction.


  1. Place rack in the middle of the oven, and preheat to 375°F. In a large bowl, toss the rhubarb, strawberries, lemon juice, granulated sugar, cornstarch and salt. Toss until fruit is evenly coated. Set aside. 
  1. In the bowl of a food processor, combine flour, both sugars, baking powder and salt. Process until well combined, about 30 seconds. Add the cold butter and pulse until topping resembles coarse crumbs with small clumps of butter. Transfer to medium bowl and stir in oats. Set aside. 
  1. Place pie crust in a 9×2-inch pie dish. Tuck it in with your fingers, making sure it is smooth. Spoon the filling into the crust, leaving all excess liquid in the bowl. Cover the filling thickly with the topping.  
  1. Place pie dish on a foil-lined baking sheet. Bake for 40-50 minutes, until the topping is golden brown, and the fruit begins to bubble. Let rest at least 15 minutes. Serve warm with vanilla ice cream or whipped cream and enjoy!
