Description

Best Portobello Mushroom Steaks are a flavorful, meaty vegetarian alternative to traditional steak. Marinated in a savory balsamic and garlic mixture, these large mushroom caps are grilled or pan-seared to juicy perfection. Perfect as a main dish or alongside your favorite sides, they offer a rich umami flavor with tender texture.


Ingredients

  • 4 large portobello mushroom caps, cleaned and stems removed

  • 1/4 cup olive oil

  • 3 tbsp balsamic vinegar

  • 2 cloves garlic, minced

  • 1 tsp dried thyme or rosemary

  • 1 tsp soy sauce or tamari

  • Salt and freshly ground black pepper, to taste

Instructions

  • Prepare Marinade:
    In a small bowl, whisk together olive oil, balsamic vinegar, garlic, thyme, soy sauce, salt, and pepper.

  • Marinate Mushrooms:
    Place mushroom caps in a shallow dish or resealable bag.
    Pour marinade over mushrooms, turning to coat evenly.
    Let marinate for at least 30 minutes, up to 2 hours.

  • Cook Mushrooms:
    Grilling: Preheat grill to medium-high heat. Grill mushrooms 5-7 minutes per side until tender and slightly charred.
    Pan-Searing: Heat a skillet over medium-high heat. Cook mushrooms 5-7 minutes per side until golden and cooked through.

  • Serve:
    Serve warm, optionally topped with fresh herbs or a drizzle of extra marinade.
