Ingredients

Scale

Mushrooms

  • 4 large portobello mushrooms

Quinoa Mixture

  • 1 cup quinoa
  • 1 cup butternut squash, diced
  • 1/2 cup dried cranberries
  • 1/2 cup walnuts, chopped
  • 2 cloves garlic, minced
  • 1 tablespoon fresh thyme leaves
  • 2 tablespoons olive oil
  • 2 cups vegetable broth or water

Topping and Seasoning

  • 1/2 cup parmesan cheese, grated
  • Salt and pepper, to taste

Instructions

  1. Preheat Oven: Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper to prepare for baking the stuffed mushrooms.
  2. Prepare Mushrooms: Clean the portobello mushrooms by removing the stems and scraping out the gills. Brush both sides with olive oil and season with salt and pepper.
  3. Cook Quinoa: Rinse the quinoa under cold water. In a pot, cook the quinoa in vegetable broth or water until fluffy, about 15 minutes. Drain any excess liquid.
  4. Sauté Butternut Squash: In a skillet, heat olive oil over medium heat and sauté the diced butternut squash until tender, approximately 5-7 minutes. Add minced garlic and fresh thyme leaves, cooking for another 1-2 minutes until fragrant.
  5. Mix Filling: In a bowl, combine the cooked quinoa, sautéed butternut squash mixture, dried cranberries, and chopped walnuts. Mix well to evenly distribute the ingredients.
  6. Stuff Mushrooms: Spoon the quinoa mixture into each portobello mushroom cap, pressing down gently. Sprinkle grated parmesan cheese evenly over the stuffed mushrooms.
  7. Bake: Place the stuffed mushrooms on the prepared baking sheet and bake in the preheated oven for 20-25 minutes, until the mushrooms are tender and the cheese has melted and turned golden brown.

Notes

  • For a nuttier quinoa flavor, toast the quinoa in a dry skillet for 2-3 minutes before cooking.
  • You can substitute walnuts with pecans or almonds according to preference or allergies.
  • To make this dish vegan, omit the parmesan cheese or replace it with a plant-based cheese alternative.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
  • Serve with a side salad or roasted vegetables for a complete meal.
