Connecticut's unique steamed cheeseburger features a juicy patty topped with steamed cheddar for an incredibly moist, protein-packed burger. This regional family-friendly specialty delivers a distinctively different burger experience.
Form the ground beef into 4 equal-sized patties, each roughly 1-inch thick, handling gently for tenderness.
Season both sides of the patties evenly with kosher salt and black pepper.
Bring a steamer setup (or a pot with a tight-fitting lid and a steaming rack) to a rolling boil over medium-high heat, ensuring enough water to steam for at least 10 minutes.
Place each patty in a small heatproof ramekin or on a steaming tray. Cover tightly and steam for 8–10 minutes, until the patties are juicy and just cooked through (internal temperature about 160°F).
During the last 2–3 minutes of steaming, top each patty with 2 oz of thick-cut cheddar and cover until the cheese melts into a gooey blanket over the beef.
While patties steam, lightly toast the hamburger buns until warm and slightly crisp.
Transfer steamed patties with melted cheese directly onto buns. Add lettuce and tomato. Serve immediately for best texture and temperature.
