These burgers are a delightful twist on the classic, featuring a buttery surprise inside each patty for an extra juicy and flavorful bite.
Combine the ground beef, steak sauce, egg yolk, salt, and pepper in a mixing bowl until just mixed.
Avoid overmixing the meat to keep the patties tender and juicy.
Divide the mixture into four portions and shape each into a patty.
Make a small indentation in the center of each patty to prevent it from puffing up during cooking.
Press a tablespoon of cold butter into the center of each patty and seal the meat around it.
Ensure the butter is fully encased to avoid it leaking out during cooking.
Preheat the grill to medium-high heat.
Clean and oil the grill grates to prevent sticking.
Cook the patties on the grill for 4 minutes on one side, then flip and cook for another 3 minutes for medium-rare.
Adjust the cooking time based on your preferred doneness.
Remove the patties from the grill and let them rest under aluminum foil for 5 minutes.
Resting allows the juices to redistribute, keeping the burgers moist.
Toast the burger buns on the grill, cut side down, for 1 minute.
Watch closely to avoid burning the buns.
Assemble the burgers with lettuce, tomato slices, and your favorite toppings.
Customize with cheese, pickles, or condiments to your liking.
Serve the burgers warm and enjoy your delicious creation.
Pair with a side of fries or a fresh salad for a complete meal.
