Yield: Serves 4


  • 8 portobello mushrooms, stemmed and cleaned
  • 1 tablespoon olive oil
  • 20 ounces 1% extra lean ground turkey
  • 1 tablespoon fresh thyme, chopped
  • 1 clove garlic, minced fine
  • ½ red onion, medium dice
  • 1 red bell pepper, medium dice
  • 1 large tomato, medium dice
  • 1 tablespoon red wine vinegar
  • ½ cup fat free yogurt
  • 1 teaspoon extra fine capers, drained
  • 4 cornichons, chopped fine
  • 1 tablespoon fresh parsley, chopped rough


  1. Preheat a grill or grill pan on medium high heat.

  2. Rub the portobellos lightly with the olive oil and season with black pepper.

  3. Place on the grill and cook for 3 to 4 minutes on each side or until tender and cooked through.

  4. Remove the mushrooms from the grill to a plate lined with paper towels to catch any excess moisture.

  5. In a large mixing bowl combine the turkey, thyme, and garlic and mix well to combine.

  6. Portion the turkey into four five-ounce patties about ¾ inch thick.

  7. Grill the turkey patties for about 4 to 5 minutes on each side or until a meat thermometer reads 165F in the center of the patties. Remove burgers from the grill and let rest for 4 minutes.

  8. Mix the red onion, bell pepper, and tomato in a medium mixing bowl. Add the red wine vinegar and mix well, season with black pepper. In a separate mixing bowl, combine the yogurt, capers, cornichons, and parsley and mix well.

  9. To serve, place a portobello mushroom with the stem side up on a serving plate. Place a burger on top of the mushroom and top with the vegetable mixture followed by a spoonful of the yogurt sauce. Top with another portobello, stem side down. Repeat with the remaining four burgers, and serve immediately.

Thanks for posting this! I was so excited to see this dish on Biggest Loser. I would've never thought of using mushrooms as buns.
