I had never heard of Butter Burgers until we moved to the Midwest. There is a hamburger/frozen custard chain, Culvers, here that is what they are known for. I never really thought about what a Butter Burger was until I started researching it to find out what makes them different from regular hamburgers. There really is butter IN the burger!
Verdict: These were so juicy when we grilled them. We made some nice 1/3 lbs. burgers and the juices were running down our arms and faces. We all said we will be making these burgers again! I served them with some roasted corn salsa and a green salad to complete the meal.
1 cup (2 sticks) butter, frozen for at least 30 minutes
3 pounds ground beef
black ground pepper
9 slices of sharp cheddar cheese, deli or pre-sliced
For serving: hamburger buns, lettuce, sliced tomato, thinly sliced red onion
Place the ground beef in a large bowl. Using a box grater grate the frozen butter over the top of the meat.
Form the patties quickly and gently folding the butter into the beef. Shape the burgers into 8-9 patties about 3/4″ thick.
Season the patties. Place the patties on a rimmed baking sheet and season both sides with black pepper.
Heat an outdoor grill to direct, Grill for 4 minutes each side. Grill the burgers for 4 minutes — expect a few flare-ups as the butter melts. Using a thin metal spatula, flip the burgers and grill until the burgers are browned and crisp on the outside, about 4 minutes more.
Serve the burgers. If using cheese, place a slice on each patty during the last minute of grilling.
Serve immediately. On hamburger rolls that have been slathered on the cut sides with butter and toasted.
