8 burgers


  • 1 pound cremini mushrooms, halved if large

  • 3 tablespoons extra-virgin olive oil, divided

  • 5 tablespoons sherry vinegar, divided

  • 2 ½ teaspoons smoked paprika, divided

  • 2 teaspoons garlic powder

  • teaspoon salt plus 1/2 teaspoon, divided

  • Pinch of sugar

  • 2 cups sliced cucumber

  • 6 tablespoons mayonnaise

  • 2 teaspoons tomato paste

  • 2 pounds lean ground beef

  • 8 ounces piquillo or Padrón peppers

  • 6 ounces thinly sliced Manchego cheese

  • 8 brioche buns, split and toasted

  • Greens, red onion & tomato for serving


  1. In batches, pulse mushrooms in a food processor, scraping down the sides once or twice, until finely chopped.

  2. Heat 2 tablespoons oil in a large pot over medium-high heat. Add the mushrooms and cook, stirring occasionally, until browned and the liquid has evaporated, 5 to 7 minutes. Add 4 tablespoons vinegar, 2 teaspoons paprika and garlic powder. Cook, stirring, for 3 minutes. Scrape into a large bowl and spread into a thin layer. Let cool for 10 minutes.

  3. Meanwhile, combine the remaining 1 tablespoon vinegar, 1/8 teaspoon salt and sugar in a small bowl. Add cucumbers and toss to combine. Combine mayonnaise, tomato paste and the remaining 1/2 teaspoon paprika in a small bowl. Set the cucumbers and aioli aside.

  4. Preheat grill to medium-high.

  5. Add beef and the remaining 1/2 teaspoon salt to the mushrooms. Mix well. Form into 8 equal patties, about 4 inches in diameter. Toss peppers with the remaining 1 tablespoon oil in a medium bowl. Transfer to a grill basket.

  6. Oil the grill rack. Grill the burgers, flipping once, until an instant-read thermometer inserted in the thickest part registers 155 degrees F, 8 to 10 minutes total. Grill the peppers, stirring occasionally, until browned, 5 to 8 minutes total.

  7. Top the burgers with cheese and cook until melted, 1 to 2 minutes more. Serve the burgers on buns with greens, onion, tomato, the peppers, cucumbers and aioli.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
