A better (grass-fed) beef burger with microgreens, mint aioli & feta

Recipe by Ms. Renee Lynn

When it comes to cooking the perfect burger, a few things are key: Handle the meat as little as possible. Make the patties ahead, and refrigerate until you’re ready for them to hit a hot pan. For best results, use a cast-iron skillet to cook the patties.


PREP TIME: 15 minutes COOK TIME: 10 minutes TOTAL TIME: 25 minutes


For the quick-pickled onion

  • 1/2 cups apple cider vinegar
  • 1 tablespoon sugar
  • 1 1/2 teaspoons kosher salt
  • 1 red onion, thinly sliced


For the aioli

  • 2 large garlic cloves
  • 1 teaspoon kosher salt
  • 1 cup loosely packed fresh mint leaves
  • 1 ripe avocado
  • 1/4 cups olive oil
  • 2 tablespoons fresh lemon juice
  • ¼ teaspoon ground mustard


For the burger

  • 2 pounds grass-fed ground beef
  • 1 tablespoon olive oil
  • 1 tablespoon butter
  • 1 ½ teaspoons kosher salt
  • Freshly ground black pepper
  • 6 brioche buns
  • 1 ½ tablespoons chipotle in adobo sauce
  • ½ cup crumbled feta cheese
  • ½ cup microgreens



  1. To make the quick pickled onions, whisk together the first three ingredients and 1 cup water in a small bowl until the sugar and salt dissolve. Place the onion in a jar and pour the vinegar mixture over top. Let sit at room temperature for 1 hour.
  2. To make the aioli, add all the ingredients into the base of an immersion blender. Blend on high speed until all the ingredients are incorporated and you have a smooth sauce. Alternatively, blend in a food processor.
  3. To make the burgers, shape the beef into 6, 1-inch thick patties. Handle the meat as little as possible – the more you work it, the tougher it gets. Using your thumb, make a shallow depression in the center of each burger to prevent them from ballooning up. Place in the fridge to chill.
  4. Meanwhile, heat the oven to 350°F. Spread a thin layer of chipotle sauce on each bun and bake until toasted, 4 to 6 minutes.
  5. In a large cast-iron skillet over high heat, warm the oil and butter until melted. Add the patties, working in batches if needed, until browned on each side, about 6 minutes for medium-rare.
  6. Remove patties from the heat and let cool.
  7. Layer brioche buns with aioli, burger patties, a few onions, a sprinkle of feta and a handful of microgreens.
