Ingredients

For the Mushrooms

  • 4 large portabella mushrooms
  • 2 tablespoons olive oil
  • Salt and pepper to taste

For the Stuffing

  • 1 cup breadcrumbs
  • 1/2 cup grated Parmesan cheese
  • 1/4 cup chopped fresh parsley
  • 2 cloves garlic, minced
  • 1 small onion, finely chopped
  • 1/2 cup sun-dried tomatoes, chopped
  • 1 cup fresh spinach, chopped
  • 1/2 cup feta cheese, crumbled
  • 1 egg, beaten
  • Salt and pepper to taste

Optional Add-ins

  • 1/2 cup cooked quinoa
  • 1/4 cup chopped walnuts
  • 1/4 cup chopped bell peppers

How To Make Stuffed Portobello Mushrooms

First, preheat your oven to 375°F (190°C). Clean the portabella mushrooms with a damp cloth to remove any dirt. Next, gently remove the stems and scoop out the gills using a spoon to create space for the stuffing. Brush both sides of the mushrooms with olive oil and season with salt and pepper.

Step 2: Prepare the Stuffing

In a large bowl, combine the breadcrumbs, Parmesan cheese, parsley, garlic, onion, sun-dried tomatoes, spinach, and feta cheese. Then, add the beaten egg to the mixture and season with salt and pepper. Mix well until all ingredients are evenly combined. If you’re adding optional ingredients like quinoa, walnuts, or bell peppers, fold them into the mixture now.

Step 3: Stuff and Bake

Place the prepared mushrooms on a baking sheet lined with parchment paper. Next, spoon the stuffing mixture into each mushroom cap, pressing down gently to ensure it’s packed in. Lastly, bake the stuffed portabella mushrooms in the preheated oven for 25–30 minutes, or until the mushrooms become tender and the stuffing turns golden brown on top.

Step 4: Serve

Remove the mushrooms from the oven and let them cool for a few minutes. Then, serve warm as a main dish or alongside your favorite entrée.

Tips for the Best Stuffed Portobello Mushrooms

  • Choose Fresh Mushrooms: Select firm, fresh portabella mushrooms with a smooth cap. Avoid any that appear slimy or have dark spots.
  • Pre-Cook the Stuffing Ingredients: Sauté the onions and garlic before mixing them into the stuffing. This step enhances their flavor and ensures they’re fully cooked.
  • Add Moisture to the Stuffing: If the stuffing mixture seems too dry, add a splash of vegetable broth or a bit more olive oil to keep it moist and cohesive.
  • Experiment with Cheeses: While feta and Parmesan are excellent choices, try other cheeses like mozzarella, goat cheese, or even blue cheese for different flavor profiles.
  • Top with a Crunch: Sprinkle some panko breadcrumbs mixed with a bit of olive oil on top of the stuffing before baking for an extra crunchy topping.

Common Mistakes to Avoid

  • Overcrowding the Baking Sheet: Give each mushroom enough space on the baking sheet. Overcrowding causes uneven cooking.
  • Undercooking the Mushrooms: Ensure the mushrooms bake until tender. Undercooked mushrooms turn out tough and less enjoyable.
  • Too Watery Stuffing: Avoid adding too much liquid to the stuffing mixture. The mushrooms release moisture as they cook, so a stuffing that’s too wet becomes soggy.
  • Skipping the Pre-Bake Seasoning: Don’t forget to season the mushrooms with salt and pepper before adding the stuffing. This step infuses flavor into the mushrooms themselves.
