Portobello Cap Mushroom Burgers


Tasty Portobello cap mushroom burgers are a mouthwatering vegetarian alternative that demonstrates the incredible versatility of mushrooms in the culinary world. These burgers redefine the concept of a meatless patty by featuring large, meaty Portobello mushroom caps as the star of the show. Grilled or roasted to perfection, these caps offer a savory, umami-rich flavor and a satisfyingly hearty texture that can rival any traditional burger.

The preparation of these mushroom burgers often involves marinating the Portobello caps in a flavorful mixture of balsamic vinegar, olive oil, garlic, and herbs, infusing them with an extra layer of depth and complexity. Once grilled or roasted, the mushrooms develop a smoky, charred exterior while remaining juicy and tender inside. They are typically served on a toasted bun with all the fixings you’d expect from a classic burger, such as lettuce, tomato, onions, and condiments like mayo or ketchup.

One of the joys of savoring Portobello cap mushroom burgers is the explosion of flavors and textures with each bite. The umami-rich mushrooms, combined with the freshness of the vegetables and the creaminess of the condiments, create a truly satisfying and wholesome burger experience. Whether you’re a vegetarian or simply seeking a delicious meatless option, these burgers are a delightful and flavorful choice that will leave your taste buds craving more.

For the Portobello Marinade

  • 4 large Portobello mushroom caps
  • 1/4 cup balsamic vinegar
  • 2 tsp olive oil
  • 2 cloves garlic, minced
  • 1 tsp dried thyme
  • 1 tsp dried rosemary
  • salt and black pepper to taste

For Assembling

  • 4 burger buns choose vegan buns for a vegan burger
  • 4 lettuce leaves
  • 1 large tomato, sliced
  • 1 red onion, thinly sliced
  • 4 slices vegan cheese optional
  • ketchup, mustard, vegan mayonnaise, or your favorite condiments


  • In a small bowl, whisk together the balsamic vinegar, olive oil, minced garlic, dried thyme, dried rosemary, salt, and black pepper to create the marinade.
  • Clean the Portobello mushroom caps by gently wiping them with a damp paper towel or brushing off any dirt. Remove the stems and gills if desired.
  • Place the mushroom caps in a shallow dish, gill side up. Pour the marinade over the mushrooms, ensuring they are well coated. Let them marinate for at least 15 minutes, or longer if time allows. You can marinate them in the refrigerator for a few hours for a more intense flavor.
  • Preheat your grill or a grill pan over medium-high heat. Once hot, grill the marinated Portobello mushrooms for about 4-5 minutes on each side, or until they are tender and have grill marks. You can also use a stovetop skillet if you don't have a grill.
  • During the last minute of grilling, add a slice of vegan cheese to each mushroom cap, if using. Cover the grill or pan to help the cheese melt.
  • While the mushrooms are grilling, toast the burger buns on the grill or in a toaster until they're lightly browned.
  • To assemble the Portobello Mushroom Burgers, start with the bottom bun, add a lettuce leaf, a grilled Portobello mushroom cap with melted cheese, a slice of tomato, and some red onion slices. Top with your choice of condiments, and finish with the top bun.
  • Serve the burgers immediately with your favorite side dishes, such as fries, coleslaw, or a fresh green salad.
