How to Make the Perfect Autumn Harvest Stuffed Portobello
Getting these stuffed mushrooms ready is a straightforward process that yields incredible results. You’ll be amazed at how simple it is to create such a flavorful dish!
- Step 1: First things first, preheat your oven to 375°F (190°C). This ensures everything cooks evenly and the mushrooms get nice and tender.
- Step 2: Gently clean your portobello mushrooms with a damp paper towel – we want them clean but not waterlogged. Carefully remove the stems and scrape out the dark gills from the underside of the caps. This creates more room for our delicious filling.
- Step 3: Cook the diced butternut squash in boiling water until it’s tender, which usually takes about 10-15 minutes. Once tender, drain it well and set it aside.
- Step 4: Heat a little olive oil in a skillet over medium heat. Add your finely chopped onions and minced garlic, and sauté them until they become translucent and fragrant, about 3 minutes. The aroma will start to fill your kitchen!
- Step 5: Toss the chopped kale into the skillet with the onions and garlic. Cook, stirring occasionally, until the kale just begins to wilt, which takes another 2-3 minutes.
- Step 6: Now for the star of the show – the filling! In a large bowl, combine the cooked quinoa, tender butternut squash, the sautéed onion and garlic mixture, shredded cheese, chopped walnuts (if you’re using them for that extra crunch), dried thyme, dried rosemary, salt, and pepper. Mix everything together until it’s well combined. This savory mixture is what makes this an Easy Autumn Harvest Stuffed Portobello.
- Step 7: Generously fill each portobello mushroom cap with the quinoa mixture. Gently press the filling down to pack it in, making sure to get a good amount in each one.
- Step 8: Arrange your beautifully stuffed mushrooms on a baking sheet. Drizzle a little more olive oil over the tops and give them a final sprinkle of salt and pepper. This is another step in making this an Easy Autumn Harvest Stuffed Portobello.
- Step 9: Bake for 25-30 minutes, or until the mushrooms are tender and the cheese is beautifully melted and bubbly.
- Step 10: For the perfect finishing touch on your Easy Autumn Harvest Stuffed Portobello, drizzle with balsamic glaze just before serving, if you like.

How to Store and Reheat Autumn Harvest Stuffed Portobello
My favorite thing about these stuffed mushrooms is how well they keep, making them perfect for meal prep or as delicious Portobello Mushroom Autumn Sides. Once they’ve cooled completely, store any leftovers in an airtight container in the refrigerator for up to 3-4 days. If you want to keep them even longer, you can freeze them for up to 3 months! Just make sure they are wrapped tightly.
Reheating is super simple. For leftovers from the fridge, you can pop them in a 350°F (175°C) oven for about 10-15 minutes, or until heated through. If reheating from frozen, allow them to thaw in the refrigerator overnight first, then follow the same oven method, adding a few extra minutes. Microwaving works in a pinch, but the oven method gives you the best texture, keeping the mushrooms tender and the filling warm. For other great make-ahead meals, try these creamy tuscan scallops.
Frequently Asked Questions About Autumn Harvest Stuffed Portobello
What are the best things to stuff portobello mushrooms with in fall?
For fall, you can’t go wrong with seasonal vegetables like butternut squash, sweet potatoes, or Brussels sprouts. Combine them with grains like quinoa or farro, some herbs like thyme and rosemary, and a good cheese. This recipe offers a fantastic starting point for what to stuff portobello mushrooms with in fall, but feel free to experiment with other autumn produce!

How do I ensure my portobello mushrooms are tender?
