Ingredients

  • 2 medium acorn squashes (about 1.5 pounds each)
  • 1 cup quinoa, rinsed
  • 2 cups vegetable broth (or water)
  • 1 small onion, finely diced
  • 2 cloves garlic, minced
  • 1 cup mushrooms, chopped (cremini or button work well)
  • 1 cup fresh spinach, chopped
  • 1/2 cup dried cranberries or raisins
  • 1/2 cup chopped walnuts or pecans, toasted
  • 1/2 cup grated Parmesan cheese (optional for vegetarians; omit for vegan)
  • 2 tablespoons olive oil
  • 1 teaspoon dried thyme
  • 1 teaspoon smoked paprika
  • Salt and pepper to taste
  • Fresh parsley for garnish (optional)

Equipment

  • Baking sheet
  • Mixing bowls
  • Medium saucepan with lid
  • Skillet or sauté pan
  • Spoon and spatula
  • Knife and cutting board
  • Measuring cups and spoons
  • Aluminum foil or parchment paper (optional for baking sheet)

Instructions

  1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it.
  2. Prepare the acorn squashes: Slice each acorn squash in half from stem to tip. Use a spoon to scoop out the seeds and stringy pulp. Brush the cut sides with 1 tablespoon olive oil and sprinkle lightly with salt and pepper.
  3. Roast the squash halves: Place them cut side down on the prepared baking sheet. Roast for about 30-40 minutes until the flesh is tender and easily pierced with a fork.
  4. Cook the quinoa: While the squash roasts, rinse the quinoa under cold water. In a medium saucepan, bring the vegetable broth to a boil. Add the quinoa, reduce heat to low, cover, and simmer for about 15 minutes or until the liquid is absorbed. Remove from heat and let it sit covered for 5 minutes, then fluff with a fork.
  5. Sauté the vegetables: In a skillet over medium heat, warm the remaining 1 tablespoon olive oil. Add the diced onion and cook for 3-4 minutes until translucent. Add the minced garlic and cook for another minute. Stir in the mushrooms and cook until they release their moisture and start to brown, about 5-6 minutes. Add the chopped spinach, dried cranberries, thyme, smoked paprika, salt, and pepper. Cook until the spinach wilts, about 2 minutes.
  6. Combine the filling: In a large bowl, mix the cooked quinoa with the sautéed vegetables, toasted walnuts, and grated Parmesan cheese (if using). Taste and adjust seasoning as needed.
  7. Stuff the squash: Once the acorn squash halves are cool enough to handle, carefully turn them cut side up. Spoon the quinoa mixture generously into each squash half, pressing lightly to pack the filling.
  8. Bake again: Return the stuffed squash to the oven and bake for an additional 15-20 minutes. This allows the flavors to meld and the top to crisp slightly.
  9. Garnish and serve: Remove from oven, sprinkle with fresh parsley if desired, and serve warm.

Tips & Variations

For a vegan version, omit the Parmesan cheese or substitute it with nutritional yeast for a cheesy flavor.

You can easily swap quinoa for other grains like farro, bulgur, or couscous depending on your preference.

Add chopped fresh herbs like sage or rosemary for a more aromatic stuffing.

Try adding cooked lentils or crumbled tofu for extra protein.

For a nut-free option, replace walnuts with pumpkin seeds or omit nuts altogether.
