01 - Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper and set aside.
02 - In a large mixing bowl, combine the ground beef, minced garlic, grated ginger, panko breadcrumbs, egg, green onions, soy sauce, sesame oil, gochujang, brown sugar, black pepper, and salt. Gently fold the mixture until evenly incorporated, being careful not to overwork the meat.
03 - Using your hands or a small scoop, roll the mixture into approximately 20 uniform meatballs. Place them on the prepared baking sheet with space between each for even cooking.
04 - Bake for 15–18 minutes, or until the meatballs are golden brown on the outside and cooked through to an internal temperature of 160°F (71°C).
05 - While the meatballs bake, combine the soy sauce, honey, gochujang, sesame oil, rice vinegar, and minced garlic in a small saucepan. Heat over medium, whisking constantly, until the glaze thickens slightly, about 2–3 minutes. Remove from heat.
06 - In a small bowl, whisk together the mayonnaise, sriracha or gochujang, lemon juice, and sugar until smooth. Adjust the heat level to your preference.
07 - Once the meatballs are fully cooked, transfer them to a large bowl. Drizzle the warm Korean BBQ glaze over the top and gently toss to coat each meatball evenly.
08 - Arrange the glazed meatballs on a serving platter alongside the spicy mayo dip. Garnish with additional sliced green onions and toasted sesame seeds if desired. Serve immediately while hot.
