In a large bowl, mix ground beef, gochujang, soy sauce, garlic, ginger, sugar, sesame oil, chopped onions and salt and allow the mixture to rest for 30 minutes or up to 24 hours in a refrigerator.
Divide the meat into four portions and form round patties, with a slight depression in the middle to prevent the burgers from puffing out into a dome-shape while cooking.
Set your air fryer to 360F for 10 minutes and place the patties in a single layer in the air fryer basket.
Make the Gochujang Mayonnaise: While the patties cook, mix together the mayonnaise, gochujang, sesame oil, sesame seeds and scallions.
Using a meat thermometer, ensure that the meat has reached an internal temperature of 160F and remove to a serving tray.
Serve the patties with hamburger buns and the gochujang mayonnaise.
Nutritional Info does not include buns
I suspect the final recipe has less fat since the air fryer renders fat into the basket. Either way, these are keto/lowcarb so enjoy!
