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.

Ingredient Checklist


Instructions Checklist
  • Preheat grill to medium-high.

  • Coat mushrooms with cooking spray and sprinkle with pepper. Grill, turning occasionally, until tender, 10 to 12 minutes total.

  • Meanwhile, mix mayonnaise, ketchup and relish in a small bowl.

  • 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.
