Grilled Portobello mushrooms are a delicious and healthy alternative to meat, offering a rich, umami-packed flavor that satisfies even the most discerning palates. Perfect for summer BBQs, weeknight dinners, or gourmet appetizers, these mushrooms are marinated in a savory blend of olive oil, garlic, and balsamic vinegar, then grilled to smoky perfection.

  • Total Time: 25 minutes
  • Yield: 4 servings 1x

Ingredients

Scale
  • 4 large Portobello mushrooms
  • 3 tablespoons olive oil
  • 2 tablespoons balsamic vinegar
  • 3 garlic cloves, minced
  • 1 teaspoon dried thyme
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • Fresh parsley, chopped (for garnish)

Instructions

  1. Clean the mushrooms by gently wiping with a damp paper towel. Remove stems and gills if desired.
  2. Whisk together olive oil, balsamic vinegar, minced garlic, thyme, salt, and pepper to make the marinade.
  3. Place mushrooms in a shallow dish, pour marinade over them, and let sit for 15-20 minutes.
  4. Preheat grill to medium-high heat. Grill mushrooms cap-side down for 5-6 minutes, then flip and grill another 4-5 minutes.
  5. Serve hot, garnished with fresh parsley.

Notes

  • Choose fresh, firm Portobellos with no dark spots for best results.
  • Don’t skip the marinade—it enhances flavor and prevents dryness.
  • Grill on high heat for a nice sear and smoky taste.
  • Use a grill basket for smaller mushrooms to prevent them from falling through.
