How to Make Mushroom Quinoa Stuffed Squash
Ingredients for Mushroom Quinoa Stuffed Squash
- 2 medium acorn squashes
- 8 oz sliced baby bella (cremini) mushrooms
- 1/2 cup finely chopped shallots
- 2 cloves garlic, minced
- 6 sprigs fresh thyme
- 1/2 cup dry quinoa
- 1 cup vegetable broth (or chicken broth)
- 3/4 cup whole milk (or cashew milk for dairy-free)
- 6 tbsp grated Parmesan cheese
- 2 to 3 tbsp balsamic glaze
- Pomegranate arils for garnish (optional)
Instructions for Preparing Mushroom Quinoa Stuffed Squash
- Roast the Acorn Squash: Preheat your oven to 425°F. Cut the acorn squash in half lengthwise, scoop out the seeds, and brush the flesh with olive oil. Season with salt, and roast the squash halves flesh-side down on a baking sheet for about 30 minutes or until tender.
- Prepare the Quinoa Filling: While the squash is roasting, heat olive oil in a large skillet over medium-high heat. Add the mushrooms and shallots, and sauté for 6-8 minutes until softened. Add minced garlic and cook for another minute. Stir in the quinoa and toast the grains for 1-2 minutes. Add vegetable broth, milk, salt, and pepper, and bring to a simmer. Add fresh thyme sprigs, cover, reduce heat to low, and cook until the quinoa absorbs the liquid and becomes fluffy (about 17-20 minutes). Stir in the Parmesan cheese and remove the thyme sprigs.
- Stuff the Squash: After the acorn squash is roasted, remove it from the oven. Stuff each squash half with the quinoa and mushroom mixture. Sprinkle the remaining Parmesan cheese over the top and return to the oven for 10-15 minutes until the cheese is golden.
- Finish with Balsamic Glaze: Drizzle the stuffed squash with balsamic glaze and garnish with pomegranate arils (if desired) for a festive touch.
