Savory grilled portobello mushroom burgers, topped with a creamy house sauce, fresh lettuce, and ripe tomatoes, served on toasted buns. A delicious and satisfying alternative to traditional burgers.

Ingredients

Scale
  • 4 large portobello mushroom caps
  • 2 tablespoons olive oil
  • 1 teaspoon balsamic vinegar
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon salt
  • 4 burger buns
  • 4 slices provolone cheese (optional)
  • Lettuce leaves
  • Tomato slices
  • House Sauce:
  • 1/2 cup mayonnaise
  • 2 tablespoons ketchup
  • 1 tablespoon relish
  • 1 teaspoon mustard
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon garlic powder
  • Pinch of paprika

Instructions

  1. Prepare the portobello mushrooms: Gently wipe the mushroom caps clean with a damp cloth. Remove the stems. In a shallow dish, whisk together olive oil, balsamic vinegar, garlic powder, black pepper, and salt. Place the mushroom caps gill-side up in the marinade and let sit for 10-15 minutes.
  2. Make the house sauce: In a small bowl, combine mayonnaise, ketchup, relish, mustard, onion powder, garlic powder, and paprika. Stir well until smooth. Set aside.
  3. Preheat grill to medium-high heat.
  4. Grill the mushrooms: Place the marinated mushroom caps on the preheated grill, gill-side down. Grill for 5-7 minutes per side, or until tender and slightly charred. If using cheese, place a slice on each mushroom during the last minute of grilling to melt.
  5. Toast the buns: While the mushrooms are grilling, lightly toast the burger buns on the grill or in a toaster.
  6. Assemble the burgers: Spread a generous amount of house sauce on both halves of each toasted bun. Place a grilled portobello mushroom on the bottom half of each bun. Top with lettuce, tomato, and the top half of the bun.
  7. Serve immediately and enjoy your grilled portobello burgers.

Notes

  • For extra flavor, consider adding a pinch of smoked paprika to the mushroom marinade.
  • You can customize the house sauce with your favorite spices or a touch of hot sauce for a kick.
  • These burgers are excellent with a side of sweet potato fries or a fresh green salad.
  • Leftover house sauce can be stored in an airtight container in the refrigerator for up to a week.
