  • Hearty and filling: Big mushrooms provide a meaty texture that satisfies even the biggest appetites.

  • Healthy and nutrient-dense: Packed with fiber, antioxidants, and essential vitamins.
  • Quick to prepare: Ready in under 30 minutes, making it ideal for busy weeknights.

Ingredients

  • 4 large portobello mushroom caps, cleaned and stems removed
  • 3 tablespoons olive oil
  • 4 cloves garlic, minced
  • 1 small onion, finely chopped
  • 1/4 cup balsamic vinegar
  • 1 teaspoon dried thyme or 1 tablespoon fresh thyme leaves
  • 1 teaspoon dried rosemary or 1 tablespoon fresh rosemary, chopped
  • Salt and black pepper to taste
  • 1/4 cup vegetable broth (optional, for extra moisture)
  • Fresh parsley, chopped (for garnish)
  • 1 tablespoon nutritional yeast (optional, for a cheesy flavor)

Equipment

  • Large skillet or frying pan
  • Mixing bowl
  • Wooden spoon or spatula
  • Knife and cutting board
  • Basting brush (optional)
  • Measuring spoons and cups

Instructions

  1. Prepare the mushrooms: Gently wipe the mushroom caps with a damp cloth to clean them. Remove the stems carefully and set aside. This creates a nice cavity if you want to stuff them later.
  2. Make the marinade: In a mixing bowl, combine the olive oil, minced garlic, balsamic vinegar, thyme, rosemary, salt, and pepper. Mix well to create a flavorful marinade.
  3. Marinate the mushrooms: Brush the mushroom caps generously with the marinade on both sides. Let them sit for at least 10 minutes to absorb the flavors. If you’re short on time, you can proceed immediately but marinating enhances taste.
  4. Sauté the onions and stems: Chop the reserved mushroom stems finely. Heat a tablespoon of olive oil in a skillet over medium heat. Add the chopped onion and mushroom stems, sautéing until tender and fragrant, about 5 minutes.
  5. Add broth and seasoning: Pour in the vegetable broth (if using) to deglaze the pan, stirring to lift any browned bits. Cook for another 2 minutes until most of the broth evaporates and the mixture thickens slightly. Stir in nutritional yeast for a subtle cheesy flavor.
  6. Cook the mushrooms: In the same skillet or a separate one, heat the remaining olive oil over medium heat. Place the marinated mushroom caps gill-side down and cook for about 5 minutes until they start to soften and brown.
  7. Flip and baste: Flip the mushroom caps, spoon the sautéed onion mixture over the gill side of the mushrooms, and let cook another 5 minutes. Baste occasionally with leftover marinade for extra flavor and moisture.
  8. Finish and serve: Once the mushrooms are tender and juicy, remove from heat. Garnish with freshly chopped parsley and a drizzle of extra virgin olive oil if desired. Serve hot.

Tips & Variations

For an extra burst of flavor, try stuffing the mushrooms with vegan cheese or cooked quinoa mixed with sautéed vegetables before cooking.

  • Grill option: Instead of pan-frying, marinate and grill the mushrooms for a smoky flavor that pairs perfectly with fresh summer salads.
  • Spice it up: Add a pinch of smoked paprika or chili flakes to the marinade for a subtle heat.
  • Herb swaps: Fresh basil or oregano can be used in place of thyme and rosemary for a Mediterranean twist.
  • Serve with sauce: Pair with a creamy vegan sauce like a Classico Sun Dried Tomato Alfredo Sauce Recipe for an indulgent finish.
