Ingredients

Scale

Marinade and Mushrooms

  • 4 large portobello mushrooms, stems removed and dry brushed clean
  • 3 tablespoons balsamic vinegar
  • 3 tablespoons gluten-free tamari (substitute soy sauce if preferred)
  • 2 tablespoons grapeseed oil (or preferred oil)
  • 1 tablespoon vegan Worcestershire sauce (substitute vegan steak sauce)
  • 12 teaspoons liquid smoke (or 1 teaspoon smoked paprika as substitute)
  • 1 large garlic clove, minced or crushed
  • 1/2 teaspoon granulated onion
  • Salt and fresh cracked pepper, to taste

Instructions

  1. Prepare the Marinade: In a large shallow baking dish, whisk together balsamic vinegar, tamari, grapeseed oil, vegan Worcestershire sauce, liquid smoke, minced garlic, granulated onion, salt, and pepper. Taste the marinade and adjust seasonings if needed, keeping in mind the flavors will concentrate during marination.
  2. Marinate the Mushrooms: Add the cleaned portobello mushrooms to the marinade dish. Brush the marinade generously on all sides of each mushroom. Alternatively, spoon marinade over them to ensure even coverage. Allow mushrooms to sit and absorb flavors for 10-20 minutes, flipping and brushing with more marinade halfway through.
  3. Preheat the Grill or Pan: Heat a grill, grill pan, or heavy skillet on medium-high until fully hot. Lightly brush the grill or pan with oil to prevent sticking.
  4. Grill the Mushrooms: Place the marinated mushrooms on the hot grill or pan. They should sizzle upon contact. Avoid moving them initially; gently press down with a spatula or tongs to ensure good contact. Grill the mushrooms for 4-5 minutes to achieve a nice sear.
  5. Flip and Finish Cooking: Turn the mushrooms over and continue grilling the other side for another 4-5 minutes until browned and tender. Add more oil or brush additional marinade as desired during cooking to enhance flavor and prevent drying.
  6. Serve: Remove mushrooms from heat and enjoy them as a satisfying main dish or side.

Notes

  • Use dry brushing to clean mushrooms instead of washing with water to prevent them from becoming soggy.
  • Adjust the amount of liquid smoke or smoked paprika according to your preferred smoky intensity.
  • You can use a grill, grill pan, or skillet depending on your available equipment and weather conditions.
  • For extra flavor, allow mushrooms to marinate for the full 20 minutes or longer if time allows.
  • These mushroom steaks pair well with side dishes like roasted vegetables, salads, or grains.
