Cook Time



  • 2 acorn squash (or other small squash for roasting), halved and seeds removed
  • 1 tablespoon olive oil
  • 8 ounces Shiitake mushrooms, sliced
  • 1 medium onion, finely chopped
  • 1-2 tablespoons fresh rosemary, chopped
  • 1/2 cup dried cranberries

  2. On a greased or foil-lined sheet pan, place squash cut side down on pan. Roast for 30 or until browning achieved.
  3. While the squash roasts, in a large skillet or pan, heat olive oil on medium-high heat. Add the onions and mushrooms and cook for 5-7 minutes (until slightly both mushrooms and onions slightly browned).
  4. Stir in the rosemary and cook an additional 2-3 minutes. Turn off the heat.
  5. Transfer the onion mixture to a large mixing bowl. Combine the quinoa and cranberries. Stir well to combine. Set aside.

  7. Optional: Return the stuffed squash to the oven to heat the stuffing for an additional 2 minutes.
  8. Turn off the oven. Serve with a side salad or other non-starchy vegetables for a delicious meal.
