Marionberry Pie

Jump to Recipe

Quick Bite

Marionberry pie is Oregon’s signature berry dessert, made with sweet-tart marionberries baked into a flaky crust. It is deep purple, juicy, summery, and basically the Willamette Valley in pie form.

History

The marionberry was developed in Oregon by the USDA and Oregon State University’s berry breeding program. It was introduced in the 1950s and named after Marion County, where much of the testing took place. Oregon did not just adopt this berry; it helped create it.

Marionberries are a type of blackberry, but they have their own personality. They are known for being juicy, aromatic, sweet, tart, and slightly earthy, with a flavor that feels more intense than a standard blackberry. That bold flavor makes them excellent for pies, jams, syrups, ice cream, cobblers, and sauces.

The Willamette Valley became the heart of marionberry country. Oregon’s climate is ideal for caneberries, and the state produces a huge share of the marionberries people eat. That local abundance helped make marionberry pie a natural Oregon dessert.

A great marionberry pie should not taste like generic berry filling. The crust should be flaky, the filling should be glossy and tart-sweet, and the berries should still taste like berries rather than sugar wearing purple.

Fun Facts

• Marionberries were developed in Oregon and named for Marion County.

• 5 cups marionberries, fresh or frozen
• ¾ cup granulated sugar, plus more if berries are very tart
• ¼ cup cornstarch
• 1 tablespoon lemon juice
• 1 teaspoon lemon zest, optional
• ¼ teaspoon salt
• 1 tablespoon butter, cut into small pieces

For finishing

• 1 egg beaten with 1 tablespoon water
• Coarse sugar, optional

Instructions

1. Make the crust: Whisk flour, salt, and sugar in a bowl.
2. Cut in butter: Cut in the cold butter until the mixture has pea-size pieces.
3. Add water: Add ice water gradually and mix just until the dough holds together.
4. Chill: Divide into two disks, wrap, and chill for at least 1 hour.
5. Heat the oven: Heat the oven to 400°F.
6. Roll bottom crust: Roll out one dough disk and fit it into a 9-inch pie plate.
7. Make the filling: In a bowl, gently mix marionberries, sugar, cornstarch, lemon juice, lemon zest if using, and salt.
8. Fill: Pour the filling into the crust and dot with butter.
9. Add top crust: Roll out the second crust and place it over the filling, or cut into strips for a lattice.
10. Seal: Seal and crimp the edges.
11. Finish crust: Brush with egg wash and sprinkle with coarse sugar if desired.
12. Vent: Cut vents if using a solid top crust.
13. Start baking hot: Bake for 20 minutes at 400°F.
14. Finish baking lower: Reduce heat to 350°F and bake for 35 to 45 minutes more, until the crust is golden and the filling bubbles.
15. Cool: Cool for at least 2 hours before slicing.

Traditional note: To make it more traditional, use Oregon marionberries when you can get them, keep the filling simple, and let the berry flavor lead. A scoop of vanilla ice cream is not required, but Oregon will understand if you add one.
