Ingredients

  • 1 pound ground sirloin
  • ½ pound ground brisket
  • ½ pound ground meat from beef back ribs
  • 16 small portobello mushrooms , stems removed
  • 1 tablespoon sesame seeds
  • Olive oil
  • Kosher or fine sea salt
  • Freshly ground black pepper

Instructions

  • In a medium bowl, combine ground meats, 1½ teaspoons of salt and ½ teaspoon of pepper. Shape mixture into patties, about 3 inches in diameter and 1-inch thick. Press an indentation into the center of each patty.
  • In a large sauté pan set over medium-high, heat 1 tablespoon of olive oil. Add patties and cook, covered, for 6-8 minutes per side or until an instant-read thermometer inserted into the side of the burger reads 160°F. Transfer to a plate and cover to keep warm.
  • Meanwhile, generously brush mushrooms with olive oil and season with salt and pepper to taste. In a large sauté pan set over medium-high, cook in batches for 2-3 minutes each side or until golden and tender. Sprinkle half of the cooked mushrooms with sesame seeds. These will be the “tops”.
  • Place half of the cooked mushrooms top-side down. Add beef patties and desired toppings. Sandwich with remaining mushrooms, top-side up, to serve.
  • Serving suggestion: Top burgers with spring mix, heirloom tomatoes, red onions, and horseradish mayonnaise.
  • To make horseradish mayo: Stir together ½ cup mayo (I use soy-free mayo), 2 teaspoons of prepared horseradish, 1 teaspoon of drained and chopped capers, 1 teaspoon of lemon juice, 1 teaspoon of finely chopped fresh dill, and salt and pepper, to taste.
