    I love mushrooms because they have a nice meaty texture and they are loaded with umami flavor. They don't replace meat exactly, but they make a great substitute in many recipes like Vegan Meatballs, and Vegan Bolognese Sauce. Even before I went vegan, I LOVED making Grilled Portobello Mushroom Steaks and Burgers. They are light, yet still satisfying!

    So, if you're looking for more Vegan Dinner Recipes to add to your rotation, you may want to give these mushroom steaks a try. You don't need an outdoor grill to char them to perfection either. A Grill Pan works great or you can use a regular skillet. You won't get the grill marks with the skillet, but they will still be smoky and savory!

    What do I need?

    (FULL INGREDIENT AMOUNTS IN RECIPE CARD BELOW)

    The ingredients are fairly simple. You just need 4 large portobello mushrooms and for the marinade, you'll need balsamic vinegar, tamari, grapeseed oil, vegan worcestershire sauce, fresh garlic, liquid smoke, granulated onion, salt, and fresh cracked pepper.

    How to make Grilled Portobello Mushroom Steaks

    3 process photos of making marinade, marinating and grilling mushrooms.

    STEP 1 - In a large and shallow baking dish, whisk all the marinade ingredients together. Taste and add more seasoning if desired.

    STEP 2 - Add the mushrooms to the dish and liberally brush the marinade on all sides. You can also spoon it on. Let them sit for 10-20 minutes, flipping and brushing again midway through the marinating time.

    STEP 3 - Heat a Grill, Grill Pan OR Skillet over medium-high heat. When fully heated, brush with oil and place the mushrooms on top. Don't move them once they are in the pan, just gently press down with a spatula or tongs. Give them a minimum of 4-5 minutes so they sear. Flip over and sear the other side, adding more oil if needed (you can also brush on more marinade). Grill until browned and tender about 4-5 minutes

    TIPS

    • Use a dry, slightly damp paper towel or a soft brush to clean each mushroom. They are like sponges and will absorb a lot of water which can make them soggy.
    • It's very important to heat the pan/grill thoroughly before adding the mushrooms or they won't sear properly. They should sizzle when they hit the pan.
    • Don't overcrowd the pan or the mushrooms will steam and cause a lot of moisture.

    Serving Suggestions

    Pretty much anything goes! You can serve them with French Fries, Vegan Potato Salad, Grilled Vegetables, Vegan Caesar Salad, Roasted Potatoes, Vegan Macaroni Salad or Tofu Scramble.

    You can also serve them in a burger bun with Roasted Peppers, Vegan Pesto, and Grilled Red Onion. It's delicious!

      First time cooking mushroom caps at all and these were amazing! Even my husband who hates mushrooms kept commenting about the smell of them and they tasted just as good!
