From: EatingWell Magazine, June 2019

Portobello mushrooms stand in for meat patties in this recipe for veggie burgers with all the fixings. Mushrooms are a source of glutamate, a naturally occurring compound that gives the fungi their umami flavor. But to really give these "patties" a savory boost, we brush them with steak sauce. Add a simple side salad or some grilled veggies for a satisfying and easy dinner on the grill.

  • 4 portobello mushroom caps, gills removed if desired
  • Cooking spray
  • ¼ teaspoon ground pepper
  • 2 tablespoons mayonnaise
  • 1 tablespoon ketchup
  • 1 tablespoon sweet pickle relish
  • 4 teaspoons steak sauce
  • 4 slices American cheese
  • 4 whole-wheat buns, toasted if desired
  • 1 cup shredded iceberg lettuce
  • 4 large tomato slices
  • Thinly sliced red onion & pickles (optional)


  • Prep

  • Ready In

  1. Preheat grill to medium-high.
  2. Coat mushrooms with cooking spray and sprinkle with pepper. Grill, turning occasionally, until tender, 10 to 12 minutes total.
  3. Meanwhile, mix mayonnaise, ketchup and relish in a small bowl.
  4. Transfer the mushrooms to a plate and pat dry with paper towels. Brush with steak sauce and top the gill side of each mushroom with a slice of cheese. Return the mushrooms to the grill and cook until the cheese is just melted, about 1 minute more. Serve on buns with the sauce, lettuce, tomatoes and onion and pickles, if desired.

My husband and I really liked this and we’ll definitly make it again. The only change we made was using Cheddar cheese rather than American.
