01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
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. Mix gently until just combined—avoid overworking the mixture to keep the meatballs tender.
03 - Roll the mixture into approximately 20 small, evenly sized meatballs and arrange them on the prepared baking sheet with space between each one.
04 - Bake for 15–18 minutes until the meatballs are browned on the outside and cooked through to an internal temperature of 160°F.
05 - While the meatballs bake, whisk together the soy sauce, honey, gochujang, sesame oil, rice vinegar, and minced garlic in a small saucepan. Heat over medium heat, stirring occasionally, until the sauce slightly thickens, about 2–3 minutes. Remove from heat and set aside.
06 - In a small bowl, whisk together the mayonnaise, sriracha or gochujang, lemon juice, and sugar until smooth and creamy. Adjust the spice level to your preference.
07 - Once the meatballs are fully cooked, transfer them to a large bowl and gently toss with the prepared Korean BBQ sauce until evenly coated.
08 - Serve the glazed meatballs hot alongside the spicy mayo dip. Garnish with additional sliced green onions and toasted sesame seeds if desired.
