1 cup uncooked whole-grain (not pearled) farro, such as Bob's Red Mill
3 cups water
1/2 cup dried cherries, chopped
2 tablespoons olive oil
1 cup chopped yellow onion (from about 1/2 large onion)
1/2 cup finely chopped celery (from about 2 small ribs)
1/2 cup finely chopped carrot (from about 1 large carrot)
1 tablespoon chopped fresh sage
1 15- to 16-oz. can no-salt-added cannellini beans, drained and rinsed
1/2 cup chopped hazelnuts, toasted
1 1/2 teaspoons kosher salt
1 teaspoon black pepper
3 medium acorn squash (about 1 1/2 lb. each)
1/4 cup unsalted butter, melted
How to Make It
Rinse farro under cold running water. Combine farro and water in a medium saucepan; bring to a boil over high heat. Reduce heat to medium-low and simmer, stirring occasionally, until farro is tender, about 30 minutes. Stir in cherries after 27 minutes of cooking time. Drain cooked farro mixture.
Heat oil in a medium skillet over medium heat. Add onion, celery and carrot; cook, stirring often, until tender and beginning to brown, 10 to 12 minutes. Add sage; cook, stirring constantly, for 1 minute. Remove from heat and stir in farro mixture, beans, hazelnuts, 3/4 teaspoon of the salt and 1/2 teaspoon of the pepper.
Cut each squash in half lengthwise; scoop out and discard seeds. Place squash cut-side up on a large rimmed baking sheet. (Trim bottoms, if necessary, so squash will sit flat.) Brush insides of squash with 2 tablespoons of the butter; sprinkle with remaining 3/4 teaspoon salt and 1/2 teaspoon pepper. Bake until tender, about 45 minutes.
Spoon farro mixture evenly into squash halves, pressing lightly and mounding in the center. Drizzle farro with remaining 2 tablespoons butter. Return to oven and bake until filling is lightly browned, 10 to 15 minutes.
