Method
Prep the fruit filling
- Heat oven to 425°F (220°C). Place a sheet pan in the oven while it heats so the bottom crust bakes crisp.
- Combine rhubarb, strawberries, granulated sugar, brown sugar, cornstarch, lemon juice, cinnamon, and salt in a mixing bowl. Toss until the fruit is evenly coated and glossy.
Assemble the pie
- Fit one pie crust into a pie dish and trim the edges. Spoon the fruit filling into the crust, keeping it level.
- Cover with the second pie crust and seal the edges by crimping or pressing gently. Cut 4 to 6 vents in the top crust so steam escapes.
- Brush the top crust with milk and sprinkle turbinado sugar if using. Dot with butter for a deeper golden color.
Bake
- Bake at 425°F (220°C) for 15 minutes. Look for bubbling filling near the vents and a lightly set crust.
- Reduce heat to 350°F (175°C) and bake for 20 minutes. Bake until the crust is deep golden and the filling bubbles steadily, not just at the edges.
Cool & slice
- Let the pie cool for at least 2 hours before slicing. The filling should thicken as it cools, so the slices hold together.
Notes
Prep ingredients ahead so fruit can be mixed and assembled quickly before the oven is ready. Store covered in the refrigerator up to 3 days; reheat individual slices in a 300°F (150°C) oven for 10–15 minutes. Freezing is best only for the unbaked assembled pie (wrap well and freeze up to 2 months); bake straight from frozen with a longer bake time. For a lighter option, use a reduced-sugar filling by lowering granulated sugar to 1/2 cup and relying on the fruit’s natural sweetness.
