These Autumn Harvest Stuffed Portobello Mushrooms are a hearty and flavorful celebration of fall, bringing together earthy mushrooms with a savory blend of quinoa, sausage, and seasonal produce. The sweetness of diced butternut squash and dried cranberries perfectly balances the savory notes of the ground sausage and aromatic garlic and thyme. Toasted walnuts add a delightful crunch to every bite, making this a satisfying and complete meal that is as nutritious as it is delicious.

To prepare this dish, start by cooking the quinoa in vegetable broth for added depth of flavor while you sauté the sausage and butternut squash until tender. After combining these with the onions, herbs, and textures of nuts and fruit, the mixture is piled high into cleaned portobello caps and topped with a sprinkle of parmesan cheese. Baked until the mushrooms are tender and the cheese is golden and melted, these stuffed portobellos make for an impressive main course or a robust side dish for any autumn gathering.

Key Ingredients

• 5-6 portobello mushrooms
• 1 cup quinoa
• 1 lb ground sausage
• 1 cup butternut squash, diced
• 1/2 cup dried cranberries

Step-by-Step Instructions

1. Preheat your oven to 375°F (190°C) and line a large baking sheet with parchment paper.
2. Clean the portobello mushrooms by removing the stems and scraping out the gills with a spoon; brush the caps with olive oil and season with salt and pepper.
3. In a medium saucepan, cook the quinoa in vegetable broth over medium heat until all liquid is absorbed and quinoa is fluffy, about 15 minutes.
4. In a large skillet, brown the sausage over medium-high heat until cooked through, then remove the meat and set aside.
5. In the same skillet, sauté the diced butternut squash in olive oil until tender, then add the onion, garlic, and thyme and cook for another 2 minutes.
6. In a large mixing bowl, combine the cooked quinoa, sausage, sautéed squash mixture, dried cranberries, and chopped walnuts.
7. Generously stuff each mushroom cap with the quinoa and sausage mixture and place them on the prepared baking sheet.
8. Top each mushroom with grated parmesan cheese and bake for 20–25 minutes until the mushrooms are tender and the cheese is golden brown.
9. Remove from the oven and allow the mushrooms to cool for 5 minutes before serving.
