Autumn Harvest Stuffed Portobello Mushrooms Ingredients

For the Stuffing

  • Portobello Mushrooms – The star of the dish, use large, firm caps for the best stuffing experience. If unavailable, large cremini mushrooms can be a great substitute.
  • Quinoa – Packed with protein and acts as the perfect binder; cooking it in vegetable broth enhances the overall taste and nutrition.
  • Butternut Squash – Adds a sweet, creamy texture to the filling; fresh or frozen diced squash works seamlessly.
  • Dried Cranberries – Provide a tart sweetness that complements savory flavors; feel free to swap with raisins or chopped dates if desired.
  • Walnuts – Their crunch and nutty flavor elevate the dish; chopped walnuts blend beautifully, but pecans or almonds can be used as alternatives.
  • Garlic – Fresh garlic amplifies the aromatic quality of the stuffing; always choose fresh for optimal flavor.
  • Fresh Thyme – Adds a lovely herbal note; if you don’t have it, dried thyme is a suitable replacement—just adjust the amount.
  • Parmesan Cheese – Melts into a deliciously crusty topping; for a vegan option, replace with vegan cheese.

For Preparation

  • Olive Oil – Used to sauté and coat the mushrooms, enhancing their flavor; avocado oil can replace it if needed.

Step‑by‑Step Instructions for Autumn Harvest Stuffed Portobello Mushrooms

Step 1: Preheat and Prepare Baking Sheet
Begin by preheating your oven to 375°F (190°C). While the oven warms up, line a baking sheet with parchment paper. This will prevent the mushrooms from sticking and make cleanup a breeze. The parchment paper will also help the portobello mushrooms roast evenly, giving them a delightful, tender texture.

Step 2: Clean the Portobello Mushrooms
Next, clean each portobello mushroom under cool water, gently wiping any dirt. Carefully remove the stems and use a spoon to scrape out the dark gills. Afterward, brush both sides with olive oil and season generously with salt and pepper. This preparation enhances the earthy flavor of the mushrooms, making them perfect vessels for your stuffing.

Step 3: Cook the Quinoa
In a medium saucepan, combine 1 cup of quinoa with 2 cups of vegetable broth or water. Bring it to a gentle boil over medium heat, then reduce to low and cover. Let this cook for about 15 minutes, until the liquid is absorbed and the quinoa is fluffy. Once done, remove from heat and let it sit covered for 5 minutes to steam.

Step 4: Sauté Butternut Squash
While the quinoa is cooking, heat a tablespoon of olive oil in a large skillet over medium heat. Add diced butternut squash and sauté for about 8–10 minutes, stirring occasionally, until it’s tender. In the last 2 minutes of cooking, add minced garlic and fresh thyme, allowing them to bloom and fill your kitchen with an aromatic fragrance.

Step 5: Combine the Stuffing Ingredients
In a large mixing bowl, combine the cooked quinoa, sautéed butternut squash, dried cranberries, and chopped walnuts. Stir everything together until the mixture is well combined. This flavorful stuffing mixes the earthy quinoa and tender squash with the sweetness of cranberries and the crunch of walnuts, enhancing the overall profile of your Autumn Harvest Stuffed Portobello Mushrooms.

Step 6: Stuff the Mushrooms
Generously fill each portobello mushroom cap with the quinoa stuffing mixture, packing it in well. Ensure that each cap is evenly stuffed to promote even cooking and flavor distribution. After stuffing, top each mushroom with a sprinkle of parmesan cheese, allowing it to melt beautifully during baking, creating a delicious crust over the vibrant filling.

Step 7: Bake the Stuffed Mushrooms
Place the stuffed portobello mushrooms on the prepared baking sheet and bake in your preheated oven for 20–25 minutes. You’ll know they are done when the mushrooms are tender and the cheese has turned a lovely golden color. The inviting aroma wafting from the oven will make it hard to wait but will be well worth it!

Autumn Harvest Stuffed Portobello Mushrooms Recipe FAQs

What are the best mushrooms to use for stuffing?
Absolutely! For this recipe, large, firm portobello mushrooms are ideal as they hold their shape and provide a sturdy vessel for the stuffing. If you cannot find portobello mushrooms, large cremini mushrooms can serve as a great substitute.

How should I store leftover stuffed mushrooms?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. This ensures that your Autumn Harvest Stuffed Portobello Mushrooms stay fresh and delicious, ready for a quick meal at any time!

Can I freeze the stuffed mushrooms?
Of course! To freeze, prepare the stuffed mushrooms but do not bake them. Individually wrap each mushroom in plastic wrap, then place them in a freezer-safe container or bag. They can be frozen for up to 3 months. When ready to enjoy, thaw them in the refrigerator overnight, then reheat them in the oven at 350°F (175°C) for 15-20 minutes until heated through.

What should I do if my mushrooms are soggy after baking?
Very! If you find your mushrooms are soggy, it may be due to excess moisture in the gills. To prevent this, ensure you scrape out the gills completely before stuffing. Skipping this step can lead to a watery texture during baking. Also, consider baking the mushrooms for a few extra minutes to enable any excess moisture to evaporate.

Can I make this recipe gluten-free?
Definitely! This Autumn Harvest Stuffed Portobello Mushrooms recipe is already gluten-free, as it features quinoa as the base. Just ensure any broth used is also gluten-free. You can feel good about serving this wholesome dish to those with gluten sensitivities.

Are there any allergies I should consider?
Absolutely, it’s important to know! This recipe contains common allergens like nuts (walnuts), dairy (parmesan cheese), and gluten (if substituting quinoa). For a nut-free version, you can simply omit the walnuts or use seeds like sunflower or pumpkin seeds instead. For dairy-free options, use vegan cheese for the topping. Always check for allergies with your guests for happy dining!
