Ingredients

Scale

Marinade

  • 3 Tbsp balsamic vinegar
  • 3 Tbsp tamari
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 2 tsp vegan steak sauce
  • 2 tsp smoked paprika
  • 2 Tbsp olive oil

Main

  • 4 portobello mushrooms

Serving

  • Fresh leafy green salad (optional)

Instructions

  1. Prepare the marinade: In a baking dish or wide bowl, combine balsamic vinegar, tamari, garlic powder, onion powder, vegan steak sauce, smoked paprika, and olive oil. Whisk everything until well blended and cohesive to create a flavorful marinade.
  2. Marinate the mushrooms: Add the portobello mushrooms to the marinade, placing them cap side down first to coat evenly. Then flip them to coat the stem side. Let the mushrooms marinate for about 20 minutes, flipping several times and brushing with more marinade to maximize flavor absorption.
  3. Heat the grill pan: Warm a grill pan over medium-high heat and brush it lightly with olive oil to prevent sticking and promote a beautiful sear on the mushrooms.
  4. Cook the mushrooms cap side down: Place the marinated portobello mushrooms cap side down on the grill pan. Cook for 5 minutes, pressing them gently with a spatula to flatten slightly and ensure even contact and caramelization.
  5. Flip and cook the other side: Turn over the mushrooms so the stem side hits the grill pan. Continue cooking for another 4 to 5 minutes, again pressing with the spatula for even cooking and to develop a nice crust.
  6. Serve: Serve the vegan portobello steaks warm. Drizzle with any remaining marinade for extra flavor and pair with a fresh leafy green salad if desired for a wholesome meal.

Notes

  • You can substitute tamari with soy sauce if tamari is unavailable, but tamari is typically gluten-free.
  • For a smokier flavor, consider adding a small amount of liquid smoke to the marinade.
  • Ensure the grill pan is hot before placing mushrooms to get a good sear.
  • Pressing the mushrooms during cooking helps achieve a steak-like texture.
  • Leftover marinade can be boiled for a few minutes and drizzled on the mushrooms when serving, but do not reuse raw marinade directly.
  • To keep it gluten-free, verify that your vegan steak sauce is gluten-free or substitute with a gluten-free barbecue sauce.
