Cilantro Lime Burger

Ingredients

• 2 limes limes
• 0.5 cups mayonnaise
• 1 clove garlic – finely grated
• 0.5 cups cilantro – finely chopped
• 1.5 pounds ground beef
• 1.25 teaspoons kosher salt
• 0.5 teaspoons black pepper – freshly ground
• 1 tablespoon neutral oil
• 4 slices pepper jack cheese
• 4 buns brioche buns – split
• 0.5 medium red onion – thinly sliced

Instructions

1. Finely grate the zest of 1 lime and juice both limes. In a small bowl, whisk the mayonnaise with the lime juice, cilantro, and grated garlic until smooth; cover and refrigerate. Reserve the lime zest.
2. In a large bowl, gently combine the ground beef, kosher salt, black pepper, and the reserved lime zest. Form into 4 equal patties about 3/4 inch thick, making a shallow dimple in the center of each.
3. Heat a cast-iron skillet over medium-high heat (or preheat a grill to medium-high). Add the neutral oil to the skillet (or brush the grill grates).
4. Cook the patties until well browned, 3–4 minutes per side, to 130–135°F for medium-rare or 140–145°F for medium. In the last minute, top each patty with pepper jack cheese and cover to melt.
5. Place the brioche buns cut-side down in the skillet or on the grill to toast until lightly golden, 30–60 seconds. Spread the cilantro-lime mayo on the cut sides, set a patty on each bottom bun, add red onion slices, and cap with the top buns. Serve immediately.
