What Kind of Teriyaki Sauce Should I Use?

You can use store-bought teriyaki sauce for convenience, but for extra depth of flavor, consider enhancing it with a few ingredients like garlic, ginger, and brown sugar. If you’re making your own, go for a blend of soy sauce, rice vinegar, honey, and sesame oil. The key is achieving a thick, slightly sticky consistency that coats the meatballs well.

Ingredients for the Slow Cooker Teriyaki Meatballs

Frozen Meatballs: These are the foundation of this easy dish. You can use beef, turkey, or even plant-based meatballs depending on your dietary preference.

Teriyaki Sauce: The heart of the flavor. Use a quality sauce or upgrade it with your own twist by adding minced garlic, grated ginger, or a splash of pineapple juice.

Brown Sugar: Helps thicken and sweeten the sauce, balancing the saltiness of soy sauce.

Garlic and Ginger: These aromatics add warm, earthy undertones that make the sauce more complex and authentic.

Cornstarch + Water (Slurry): Optional but great for thickening the sauce toward the end of cooking.

Green Onions or Sesame Seeds (for garnish): These brighten up the final dish with color and crunch.

How To Make the Slow Cooker Teriyaki Meatballs

Step 1: Prep the Sauce

In a medium bowl, combine teriyaki sauce, brown sugar, minced garlic, and grated ginger. Stir until the sugar dissolves and the mixture is well blended.

Step 2: Add Everything to the Slow Cooker

Place frozen meatballs into the slow cooker. Pour the teriyaki mixture over the top and toss gently to coat all meatballs evenly.

Step 3: Let It Cook Low and Slow

Cover and cook on low for 4–5 hours or on high for 2–3 hours, stirring once or twice during cooking to keep the sauce evenly distributed.

Step 4: Thicken the Sauce (Optional)

If you prefer a thicker glaze, mix 1 tablespoon of cornstarch with 2 tablespoons of water and stir it into the slow cooker about 30 minutes before serving.

Step 5: Garnish and Serve

Once cooked through and coated in that glossy sauce, sprinkle with chopped green onions or sesame seeds for extra flavor and color.
