Equipment

  • Chef's knife
  • Cutting board
  • Baking pan
  • Silicone baking mat
  • Large skillet

Ingredients
 

Squash

  • 3 medium-large acorn squash
  • 1-2 tablespoons olive oil (extra virgin)
  • Salt & pepper to taste

Filling

  • 1 tablespoon olive oil (extra virgin)
  • ½ white or yellow onion (diced)
  • 4 ounces (4 large) cremini mushrooms (diced)
  • 3 cloves garlic (minced)
  • ½ cup walnuts (finely chopped)
  • 2 tablespoons tamari (or soy sauce)
  • 1 ½ cups cooked quinoa
  • 1 can chickpeas (drained & rinsed)
  • cup dried cranberries
  • 1 tablespoon fresh thyme (minced)

For serving

  • Fresh flat-leaf parsley (chopped)

Instructions
 

Squash

  • Preheat the oven to 425°F and line a baking sheet with parchment paper or a silicone baking mat.
  • Slice each acorn squash in half vertically. Using a spoon, scoop out and discard the seeds.
  • Brush the cut side of each squash half with olive oil, and season them generously with salt and pepper.
  • Place the squash halves, cut side down, on the prepared baking sheet. Roast for 15-25 minutes, or until the squash is tender and easily pierced with a fork.

Filling

  • While the squash is roasting, heat 1 tablespoon of olive oil in a large skillet over medium. Add the diced onion and mushrooms and sauté for 5-6 minutes until the onions are translucent and the mushrooms are tender.
  • Add the minced garlic and chopped walnuts to the skillet, cooking for another 1-2 minutes until fragrant.
  • Pour in the tamari, then stir in the cooked quinoa, chickpeas, dried cranberries, and fresh thyme. Mix everything well, ensuring the ingredients are evenly distributed.

Assembly

  • When the squash halves are tender, remove them from the oven. Carefully flip each half so that the cut side is facing up.
  • Spoon the prepared filling into each squash half, pressing down gently to ensure it doesn’t fall out.
  • Return the stuffed squash to the oven at 425°F and bake for an additional 5-10 minutes, allowing the flavors to meld together.
  • Remove the stuffed squash from the oven and sprinkle each half with freshly chopped parsley, then serve immediately while hot. Happy eating!

Notes

  • Squash selection: Choose acorn squash that are similar in size for even roasting.
  • Season generously: Don’t skimp on seasoning the squash before roasting.
  • Sauté the veggies thoroughly: Sauté the onions and mushrooms until they’re quite tender for the most aromatic flavor.
  • Taste as you go: Adjust the seasonings in the filling before stuffing the squash.
  • Don't overfill: Overfilling can cause the stuffing to fall out during baking. Pack them tightly but don’t go overboard. You can also serve extra filling on the side.
  • Check for doneness: You want the squash to be fork-tender but not mushy.
  • Let them rest: Allow the stuffed squash to rest for a few minutes before serving.
  • Nutritional information is a rough estimate and should not be taken as health advice.
