  • 1 (9-inch) unbaked pie crust
  • 4 cups chopped fresh rhubarb
  • 1 large egg
  • 1 ½ cups white sugar
  • 1 cup sour cream
  • ⅓ cup all-purpose flour
  • ½ cup all-purpose flour
  • ½ cup brown sugar
  • ¼ cup butter, melted


  1. Preheat and Prepare: Preheat your oven to 400°F (200°C). Place the unbaked pie crust in a 9-inch pie dish, crimping the edges as desired.
  2. Prepare Rhubarb Filling: In a large mixing bowl, combine the chopped rhubarb, egg, white sugar, sour cream, and ⅓ cup of all-purpose flour. Mix until well combined.
  3. Pour into Pie Crust: Pour the rhubarb mixture into the prepared pie crust, spreading it out evenly.
  4. Make Streusel Topping: In a separate bowl, mix together the remaining ½ cup of all-purpose flour, brown sugar, and melted butter until crumbly. Sprinkle the streusel topping evenly over the rhubarb filling.
  5. Bake: Place the pie in the preheated oven and bake for 10 minutes. Then reduce the oven temperature to 350°F (175°C) and continue baking for an additional 40-45 minutes, or until the filling is bubbly and the crust is golden brown.
  6. Cool and Serve: Allow the pie to cool on a wire rack for at least 1 hour before serving. Serve warm or at room temperature, and enjoy the delicious taste of old-fashioned goodness!

Cook Notes and Variations:

  • Fresh vs. Frozen Rhubarb: While fresh rhubarb is preferred for its vibrant flavor and texture, you can also use frozen rhubarb if fresh is not available. Thaw and drain the frozen rhubarb before using it in the pie.
  • Adjusting Sweetness: The sweetness of the pie can be adjusted according to personal preference. Feel free to increase or decrease the amount of sugar used in the filling and streusel topping to suit your taste.
  • Adding Spices: For extra flavor, consider adding spices such as cinnamon or nutmeg to the rhubarb filling or streusel topping.

Keto and Low-Carb Versions:

  • Keto Version: To make a keto-friendly version of this pie, you can replace the white sugar with a low-carb sweetener such as erythritol or stevia. Use a keto-friendly pie crust made with almond flour or coconut flour, and substitute the all-purpose flour in the filling and topping with a low-carb flour alternative such as almond flour or coconut flour. For the sour cream, use full-fat Greek yogurt or coconut cream.
  • Low-Carb Version: Similarly, for a low-carb version, use a low-carb sweetener in place of sugar and opt for a low-carb flour alternative in the filling and topping. Reduce the amount of sweetener used in the streusel topping for a lower carb count.

Frequently Asked Questions (FAQs):

Q: Can I use frozen rhubarb instead of fresh? A: Yes, you can use frozen rhubarb if fresh is not available. Be sure to thaw and drain the frozen rhubarb before using it in the pie to prevent excess moisture.

Q: Can I make the pie crust from scratch? A: Absolutely! You can make a homemade pie crust using your favorite recipe or a store-bought crust for convenience.

Q: Can I omit the streusel topping? A: While the streusel topping adds a delicious crunch and sweetness to the pie, you can omit it if desired. Simply bake the pie without the topping for a simpler version.
