Ingredients

Scale

For the Marinade

  • 2 tablespoons balsamic vinegar
  • 2.5 tablespoons extra virgin olive oil
  • 2 tablespoons low sodium soy sauce
  • 3 garlic cloves, minced
  • 1 teaspoon onion powder
  • 1 teaspoon paprika
  • 0.33 teaspoon ground cumin
  • 0.33 teaspoon smoked paprika
  • Freshly ground black pepper, to taste
  • Cayenne pepper, optional, to taste

Main Ingredient

  • 4 large portobello mushrooms, stems removed and caps wiped clean

Instructions

  1. Prepare the Marinade: In a baking dish, whisk together balsamic vinegar, extra virgin olive oil, low sodium soy sauce, minced garlic, onion powder, paprika, ground cumin, smoked paprika, black pepper, and cayenne pepper if using. This creates a flavorful base that will soak into the mushrooms.
  2. Marinate the Mushrooms: Add the cleaned portobello mushrooms to the dish and use a brush to coat each mushroom thoroughly with the marinade, making sure all surfaces are well covered to ensure maximum flavor infusion.
  3. Rest the Mushrooms: Let the mushrooms marinate for at least 10 to 15 minutes at room temperature. For a deeper taste, marinate longer if time allows, which will enhance the smoky and tangy flavors.
  4. Heat the Cooking Surface: Preheat a grill pan or large non-stick skillet over medium-high heat and lightly coat it with cooking spray. This will help achieve a beautiful sear without sticking.
  5. Cook the Mushrooms: Place the marinated mushrooms on the hot grill or skillet and cook each side for 4 to 5 minutes or until they develop a deep golden-brown color. Brush with remaining marinade periodically during cooking to keep them moist and flavorful.
  6. Serve: Transfer the cooked portobello steaks to serving plates and enjoy immediately with your choice of sides such as roasted vegetables, salad, or grains.

Notes

  • To enhance flavor, marinate mushrooms up to 1 hour in the refrigerator.
  • For extra smoky flavor, consider finishing mushrooms on an outdoor grill.
  • Substitute low sodium soy sauce with tamari for gluten-free option.
  • Use a clean brush or spoon to apply marinade to avoid contamination.
  • Portobello mushrooms are best cooked fresh but can be stored refrigerated for 1-2 days before cooking.
