Creating Korean BBQ Meatballs with Spicy Mayo Dip is a straightforward process. Follow these steps to ensure success:

1. Preheat Oven: Start by preheating your oven to 400°F (200°C).
2. Mix Meatball Ingredients: In a large bowl, combine the ground beef, panko breadcrumbs, green onions, soy sauce, sesame oil, garlic, ginger, egg, black pepper, sugar, and red pepper flakes. Mix well until all ingredients are fully incorporated.
3. Shape Meatballs: Scoop about 1-2 tablespoons of the mixture and roll it into balls. Place the formed meatballs on a lined baking sheet, ensuring they’re slightly spaced apart.
4. Bake Meatballs: Bake the meatballs in the preheated oven for 20-25 minutes, or until they are cooked through and browned on top.
5. Prepare Spicy Mayo Dip: While the meatballs are baking, prepare the dip. In a small bowl, combine the mayonnaise, sriracha, lime juice, and soy sauce. Mix well until smooth. Adjust the sriracha to your spice preference.
6. Garnish Meatballs: Once cooked, remove the meatballs from the oven and let them cool for about 10 minutes. Garnish with sesame seeds and additional sliced green onions if desired.
7. Serve: Arrange the meatballs on a serving platter alongside the spicy mayo dip.
