A Hatch green chile cheeseburger topped with roasted New Mexico green chiles and melted cheese is a Southwest carnivore's dream. This high protein, family-favorite burger has bold, smoky heat in every bite.
Shape the ground beef into four even patties, handling minimally for a tender result. Season both sides with kosher salt and black pepper.
Preheat a cast iron skillet or grill to medium-high heat. Lightly brush with canola oil to prevent sticking.
Cook the beef patties for about 3–4 minutes per side, flipping once, until well-seared and cooked to your desired doneness.
During the final minute of cooking, top each patty with sliced cheddar cheese and allow it to melt completely; tent with foil if needed for thorough melting.
Toast the hamburger buns cut-side down on the skillet or grill for 1–2 minutes until golden.
Assemble: Place patties on buns, top generously with roasted Hatch green chiles and sliced onion. Serve immediately for best flavor and texture.
