On a baking sheet, place the halved acorn squashes cut side up. Lightly drizzle them with olive oil and sprinkle generously with salt and pepper. Roast in the oven for approximately 25-30 minutes, or until the flesh is tender when pierced with a fork.
While the squashes are roasting, prepare the quinoa. In a medium saucepan, combine the rinsed quinoa and vegetable broth. Bring the mixture to a boil over medium-high heat, then reduce the heat to low. Cover and simmer for around 15 minutes, or until the quinoa is fluffy and all the liquid is absorbed.
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the finely chopped onion and minced garlic, sautéing until the onion becomes translucent and fragrant, about 3-4 minutes.
Stir in the dried cranberries, toasted walnuts, ground cinnamon, nutmeg, and the cooked quinoa. Season the mixture generously with salt and pepper to taste, stirring well to ensure all ingredients are combined.
Once the acorn squashes are perfectly roasted, remove them from the oven. Carefully spoon the quinoa stuffing mixture into each half, pressing it down slightly to pack it in.
Return the stuffed acorn squashes to the oven and bake for an additional 10-15 minutes. This allows the flavors to meld beautifully and the tops to become slightly golden.
After baking, remove the squashes from the oven and sprinkle them with fresh chopped parsley for a pop of color and freshness before serving.
Notes
Feel free to add other nuts or dried fruits to the stuffing.
