Ingredients

To Roast the Acorn Squash

  • ¼ teaspoon onion powder
  • ¼ teaspoon garlic powder
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon ground cumin
  • ½ teaspoon Kosher salt
  • ¼ teaspoon ground black pepper
  • 2 tablespoons olive oil
  • 4 large acorn squash cut in half and seeds removed

To Make the Stuffing:

  • 1 tablespoon olive oil
  • 1 onion medium-size / chopped (~1 1/4 cup)
  • 3 stalks celery chopped (~3/4 cup)
  • 1 apple peeled and cut into small ½ inch cubes
  • 2 cloves garlic minced
  • 2 ½ cups cooked quinoa from 1 cup uncooked quinoa
  • ½ cup dried cranberries chopped finely
  • ½ cup pecans coarsely chopped
  • 1 teaspoon kosher salt
  • ½ teaspoon black pepper
  • ¼ cup fresh parsley chopped, plus more as garnish
  • Handful of pomegranate seeds as garnish (optional)

Instructions

  • Preheat the oven to 400°F (204 °C). Line a baking sheet with parchment paper.
  • In a small bowl, mix together onion powder, garlic powder, cinnamon, cumin, salt, and pepper.
  • Brush the insides of acorn squash with olive oil.

  • Sprinkle each half with the spice mixture, ensuring that it is evenly distributed.
  • Arrange the squash cut-side down and roast for 40 minutes, or until a knife inserted into the flesh of one of the squash comes out easily. Let it cool on the counter for 10 minutes before stuffing.
  • While the acorn squash is roasting, make the stuffing. Heat olive oil in a large skillet over medium-high heat. Add the onion and celery, and cook, stirring frequently, until translucent, 8 to 10 minutes.
  • Add the apples and cook for 3 to 4 more minutes, or until softened.
  • Stir in the garlic and cook for 30 seconds.

  • Add the cooked quinoa, cranberries, pecans, and season with salt and pepper. Give it a stir and turn the heat to medium-low. Let it cook for 7-8 minutes, stirring occasionally to ensure it remains moist. If you feel like it is drying, add in a few tablespoons of water.
  • Taste for seasoning and add more, if necessary. At the last minute, stir in the parsley.
  • To assemble, fill each roasted acorn squash half with the stuffing and garnish it with pomegranate seeds (if using) and more parsley before serving.

Notes

Yields: This recipe makes 8 halved stuffed acorn squash, which is ideal for serving 8 as a side dish. If you are serving it as a main dish, I would recommend serving 2 halves per person. The nutritional values listed below are per serving of one half.
Filling: Take the time to cut up your apple evenly to ensure that you get some with each bite. I also recommend chopping up the cranberries for the same reason.
Make Ahead: You can prepare the quinoa stuffing 1-2 days in advance, bring it to room temperature, and store it in an airtight container in the fridge. You can also roast the squash halves a day ahead, let them cool to room temperature, and refrigerate. When you are ready to serve, reheat the filling, stuff the squash, and warm them in the oven at 275°F (135°C) until heated through.
Alternatively, you can assemble the whole thing a day in advance, bring to room temperature, and store it in an airtight container. An hour before serving, you can reheat it in a low-heat (275°F (135°C)) oven for 15 minutes, or until heated through.
Storage: After the stuffed squash has cooled to room temperature, it can be stored in an airtight container in the refrigerator for up to 3-4 days. The leftovers make the most delicious lunch the next day.
Freezing: While you can technically freeze baked acorn squash, I don’t recommend it. It causes the squash to release extra water when thawed, resulting in a mushy texture and minimal flavor.
