Step 1: Preheat Your Oven - Start by preheating your oven to 400°F (200°C) to ensure even cooking.
Step 2: Mix the Meatball Ingredients - In a large mixing bowl, combine the ground beef, salt, pepper, low-sodium soy sauce, grated ginger, minced garlic, panko crumbs, egg, and sliced green onions. Mix until just combined.
Step 3: Form the Meatballs - Shape the mixture into meatballs, about 1 to 1.5 inches in diameter, and place them on a baking sheet lined with parchment paper.
Step 4: Bake the Meatballs - Bake for about 20-25 minutes or until cooked through, reaching an internal temperature of 160°F (70°C).
Step 5: Prepare the Sauce - In a skillet, combine the low-sodium soy sauce (or coconut aminos), water, brown sugar, sesame oil, cornstarch, and crushed red pepper flakes. Stir until smooth and bubbling, then simmer for about 5 minutes until thickened.
Step 6: Coat the Meatballs - Transfer baked meatballs to the skillet with the sauce and toss to coat. Cook for an additional 2-3 minutes on low heat.
Step 7: Serve and Enjoy - Serve hot, garnished with green onions and sesame seeds. Enjoy with steamed rice or in lettuce wraps!
