Creating these fantastic Sticky Mongolian Beef Meatballs is a breeze when you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Mix Meatball Ingredients: In a large bowl, combine ground beef, breadcrumbs, egg, green onions, garlic, ginger, soy sauce, salt, and pepper. Mix until well combined.
3. Form Meatballs: Shape the mixture into small meatballs, approximately 1 inch in diameter, and place them on a baking sheet lined with parchment paper.
4. Bake the Meatballs: Bake in the preheated oven for about 15-20 minutes or until golden brown and cooked through.
5. Prepare the Sauce: While the meatballs are baking, combine brown sugar and soy sauce in a saucepan over medium heat. Stir until the sugar dissolves.
6. Thicken the Sauce: Gradually whisk in the cornstarch mixture, allowing the sauce to thicken. Remove from heat once it reaches your desired consistency.
7. Coat the Meatballs: Once cooked, remove the meatballs from the oven and transfer them to the saucepan. Gently toss them in the sticky sauce until evenly coated.
8. Serve: Transfer the saucy meatballs to a serving platter, sprinkle with sesame seeds, and garnish with additional green onions.
