Acorn Squash Stuffed with Cranberries, Wild Rice, and Chickpeas - Instapot

1/2 cup uncooked wild rice
1 teaspoon kosher salt divided
3 small acorn squashes (1 pound each), halved, lenghtwise, stems trimmed, seeded
1 tablespoon olive oil
1 medium shallot finely chopped, or 1/2 small yellow onion, finely chopped
3 cloves large garlic minced (about 1 tablespoon)
8 ounces baby bella mushrooms finely chopped, cremini
1/2 teaspoon black pepper
1 15 ounce can chickpeas rinsed and drained
1/3 cup Dried Cranberries
1/4 cup toasted pepitas or chopped pecans
1 tablespoon fresh thyme leaves chopped

Bring 1 1/2 cups water to a boil in a small saucepan. Add the rice and 1/2 teaspoon kosher salt. Reduce heat to low, cover, and let simmer until the rice is tender, about 55 minutes. Drain off any excess liquid. Set aside.
Pour 1/2 cup water into the bottom of an Instant Pot or electric pressure cooker. Place the steamer basket in the pot, then add the squash, cut sides up (they will overlap). Be sure not to exceed the max fill line. If your squash are larger and you exceed the line, cook the squash in two batches. Seal the lid, set pressure valve to sealing, and cook on HIGH (manual) for 4 minutes. Allow the pressure to release naturally for 5 minutes, then immediately vent to release any remaining pressure. Drain and arrange on a large serving plate or baking sheet.
Meanwhile, heat the olive oil in a large skillet over medium low. Add the shallot and cook until softened, about 4 minutes. Add the garlic and cook 30 seconds until fragrant, then add the mushrooms, black pepper, and remaining 1/2 teaspoon kosher salt. Increase heat to medium and cook until the mushrooms are softened and browned, about 5 to 7 additional minutes. Add the chickpeas, cranberries, pepitas, thyme, and cooked rice and stir to heat through, about 2 additional minutes. Taste and adjust seasonings as desired.
Spoon the hot filling into the squash halves. Serve immediately or keep warm in a 350 degree F oven.

To cook the squash in the oven instead of the Instant Pot: Preheat the oven to 425 degrees F. Brush a large rimmed baking sheet with extra-virgin olive oil. Slice a small piece off the bottom of each squash half so level it will sit level. Set the squash on the baking sheet, scooped sides down, and bake for 25 minutes. Remove the baking sheet from the oven and carefully turn the squash halves over. Lightly brush them with olive oil and sprinkle with salt and pepper. Return to the oven and continue baking until tender, 20 to 25 additional minutes. Stuff with wild rice–chickpea filling and enjoy.
Store leftovers in an airtight container in the refrigerator for up to 5 days. Reheat gently in the microwave or cover and reheat in the oven.
