The summer pie theme continues with a terrific version of Strawberry Rhubarb Pie which was a big hit when my parents came for lunch yesterday.

The recipe includes a few tips that I always use when baking what can be a pretty tricky pie to get right.

Fresh ripe perfect strawberries are great in summer but frozen fruit can also be used.

Blind baking the bottom crust will ensure that it remains crispy. Also, protecting the edges of the pastry with a collar of aluminum foil keeps it from over-baking on its second visit to the oven.

Any Strawberry Rhubarb filling is a bit of a challenging mixture of two ingredients that do not have equal cooking times. So, I find it much better to prepare the filling completely in advance so that the rhubarb is fully cooked and the strawberries are not overcooked and falling apart.

Following all three of these tips will help greatly to achieve a perfect pie.

Yield: 12 servings

Strawberry Rhubarb Pie with Oatmeal Crumble Topping

Prep Time: 40 minutes
Cook Time: 1 hour 10 minutes
Total Time: 1 hour 50 minutes


For the pie filling

  • 1 lb diced rhubarb
  • 1 1/4 cups sugar
  • pinch salt
  • 1 lb whole fresh or frozen strawberries
  • 1 tsp vanilla extract
  • 2 1/2 tbsp corn starch
  • 1/4 cup water

For the Butter Pastry

  • 1 cup very cold butter cut in small cubes
  • 2 ½ cups flour
  • 2 tbsp brown sugar
  • ½ tsp salt
  • 1/3 to 1/2 cup ice water, Only enough to make a dough form.
  • 1 tsp vanilla extract

For the Oatmeal Crumble

  • 1/2 tsp baking powder
  • 2/3 cup rolled oats, large
  • 2/3 cup flour
  • 1/3 cup brown sugar
  • ½ cup butter, cut in small cubes


To prepare the filling

  1. In a medium saucepan gently simmer the rhubarb, sugar and pinch salt for about 25 minutes over low heat.
  2. Add the frozen strawberries and vanilla extract.
  3. Bring to a boil simmer gently for another 5 minutes before adding a thickening slurry, made by mixing together the corn starch and water.
  4. Simmer only for an additional minute or two, stirring constantly. Remove from heat and cool to room temperature.

To prepare the butter pastry.

  1. Using a food processor or a pastry blender cut cold butter into flour, brown sugar and salt until mixture resembles a coarse meal. Small pieces of butter should still be visible.
  2. Pour vanilla into cold water then pour over the mixture and work in by tossing with a fork until dough begins to form. Use your hands as little as possible and work the dough as little as possible.
  3. Divide dough into 2 balls, flatten into 2 rounds, wrap in plastic wrap and place in the refrigerator to rest for a minimum of 20 minutes.You can make your dough the previous day but make sure you take it out of the fridge for 10 minutes to warm slightly before rolling out. Since this is a a one crust pie, freeze one of the pastry rounds for later.
  4. Roll the dough into a 12 inch round and place in the bottom of a 10 inch pie plate. Trim and flute the edges as desired. You will need to blind bake this bottom crust before adding the filling. Blind baking is essential so that the bottom crust will not get soggy.
  5. To blind bake a crust simply place a piece of parchment paper over the dough and cover the bottom of the pie plate with baking weights. (Marbles, dry beans, peas, rice or barley work just as well as anything else.) Bake at 400 degrees for about 15-20 minutes. Remove baking weights and parchment and bake for an additional 5 minutes.
  6. Cool the pastry for about 10 minutes before adding the fruit filing.

To prepare the oatmeal crumble topping

  1. In a large bowl toss together the baking powder, oats, flour and brown sugar.
  2. Using your fingers, rub the butter thoroughly through the dry ingredients.
  3. Sprinkle the crumble evenly over the fruit filling. At this point, cover the outside crust of the pie with strips of aluminum foil so that the edges will not overbake but allowing the crumble to brown evenly as in the photo above.
  4. Bake at 375 degrees F for approximately 30 -40 minutes or until the crumble s evenly golden brown. Allow the pie to cool to room temperature before cutting and serving.

Hi Barry, I have family coming, one is NF descended, both originally from NS and have been living in China (teachers). She craves rhubarb and I have some frozen and ready to use. Being here in AB I can't get new fresh strawberries like back home in the Maritimes, but I do have some nice frozen raspberries from my friend's garden I picked last summer. Can I substitute these?

Sounds like an awesome idea to me.

I always use real dairy butter for baking. If you are referring to soft margarine in tubs, it should never be used for baking. That is a recipe for disaster.

My wife just made a recipe for rhubard crumble... Won't tell her, but it was awful. Tasted too... Earthy (not in a good sense). Wish she had tried this
