Step-by-Step Instructions
1. Prepare the Meatballs
In a large mixing bowl, combine the ground beef, breadcrumbs, egg, garlic, ginger, soy sauce, green onions, and black pepper. Mix gently until just combined—avoid overmixing to keep the meatballs tender.
Shape the mixture into 1-inch meatballs and place them on a plate or tray. You should get about 18–22 meatballs depending on size.
Optional Tip: For extra flavor, lightly brown the meatballs in a skillet before adding them to the slow cooker. This step adds depth but can be skipped if you’re short on time.
2. Make the Teriyaki Sauce
In a bowl, whisk together soy sauce, brown sugar, honey, rice vinegar, sesame oil, garlic, and ginger.
Pour the sauce into the slow cooker.
3. Slow Cook
Place the meatballs into the slow cooker, gently turning them to coat in the sauce.
Cook on:
-
Low for 4–5 hours, or
-
High for 2–3 hours
The meatballs should be fully cooked and tender.
4. Thicken the Sauce
About 20 minutes before serving, mix the cornstarch with water to create a slurry. Stir it into the slow cooker.
Cover and cook on high for an additional 15–20 minutes until the sauce thickens and becomes glossy.
5. Garnish and Serve
Sprinkle with sesame seeds and fresh green onions before serving.
Serve hot over:
-
Steamed white rice
-
Brown rice
-
Fried rice
-
Noodles
-
Or as a party appetizer with toothpicks

✔️ Use fresh ginger and garlic for best flavor.
