01 - Preheat your oven to 400°F. Line a baking sheet with parchment paper for easy cleanup.
02 - In a large bowl, combine ground beef, minced garlic, chopped green onions, egg, soy sauce, panko breadcrumbs, sesame oil, gochujang, brown sugar, grated ginger, black pepper, and salt. Mix until just combined—avoid overmixing for tender meatballs.
03 - Form the mixture into 20–24 bite-sized meatballs and arrange on the prepared baking sheet, leaving space between each for even cooking.
04 - Bake for 20–25 minutes, turning once halfway through, until browned and cooked through (internal temperature should reach 160°F).
05 - While the meatballs are baking, mix mayonnaise, sriracha, lime juice, sesame oil, honey, and salt in a small bowl until smooth. Adjust sriracha to your desired heat level.
06 - Arrange cooked meatballs on a serving platter. Sprinkle with toasted sesame seeds and sliced green onions. Serve hot with the spicy mayo dip on the side.
