  • In a baking dish whisk together balsamic vinegar, oil, soy sauce, garlic, and all spices.
  • Add portobello mushrooms, use a brush to brush with the marinade on all sides.
  • Marinate for at least 10-15 minutes (the longer the better). In the meantime, you can prep your favorite side dish.
  • Heat a grill or skillet over medium-high heat and spray with cooking spray.
  • Cook the portobello mushrooms on each side for about 4-5 minutes or until deep golden brown. Brush with the remaining marinade while cooking.


  • You can use tamari, coconut aminos, or regular soy sauce (gluten-free if needed) instead of low-sodium soy sauce.
