Follow these straightforward steps to prepare and cook Korean BBQ meatballs with spicy mayo dip:

1. Preheat the Oven: Begin by preheating your oven to 400°F (200°C). Prepare a baking sheet by lining it with parchment paper for easy cleanup.

2. Mix Meatball Ingredients: In a large bowl, combine the ground beef or pork, breadcrumbs, green onions, soy sauce, sesame oil, grated ginger, minced garlic, egg, gochujang, salt, and pepper. Mix well until all ingredients are thoroughly combined.

3. Form the Meatballs: Using your hands, shape the mixture into meatballs, around 1 to 1.5 inches in diameter. Place each meatball onto the prepared baking sheet, ensuring they are evenly spaced.

4. Bake: Transfer to the oven and bake the meatballs for about 20-25 minutes, or until they’re cooked through and nicely browned.

5. Prepare Spicy Mayo Dip: While the meatballs are baking, prepare the dip. In a small bowl, combine mayonnaise, gochujang, lime juice, and sesame oil. Mix until smooth and well combined. Adjust seasoning if necessary.

6. Serve: Once the meatballs are cooked, remove them from the oven. Serve them warm alongside the spicy mayo dip. Garnish with additional green onions for an appealing presentation.
