This drool-worthy easy recipe for slow cooker teriyaki meatballs is a delicious dinner to throw in the slow cooker and serve along with a pot of rice for a complete meal!

Frozen meatballs are a great tool for getting dinner on the table on busy days. Also, try my Barbecue Meatballs or Slow Cooker Meatball Soup.

Whether you’re looking for a quick appetizer for game day or something delicious to take to a potluck, these meatballs make a quick, tasty, and easy dinner. All you need are just three ingredients and your crock pot to make these Italian-style meatballs.

I like the fact that you can change the flavors by simply choosing a meatball and/or sauce that tastes different. Although I used Island Teriyaki flavor, the Pineapple Paradise Teriyaki flavor is great too! This is a meal the whole family (and friends) is sure to enjoy.

Key Ingredients

Here is all you need to make these meatballs. Find the full recipe in the recipe card below the images.

• Meatballs – Use turkey or homestyle beef pre-cooked frozen meatballs.
• Teriyaki sauce – I use Kona Coast Island Teriyaki but their Pineapple Paradise Teriyaki is great too! You can also use a homemade teriyaki sauce.
• Sweet yellow onion – diced.

How to Make Teriyaki Meatballs

Step One – Add the teriyaki sauce, diced sweet onion, and frozen meatballs in the slow cooker.

Step Two – Toss the meatballs in the sauce.

Step Three – Cover and cook on HIGH for 2.5 hours or LOW for 4 hours. Or until the meatballs are hot on the inside. Stir occasionally for teriyaki can tend to burn in the slow cooker.

Step Four – When the cooking time is done add sliced green onion. Serve or rice or as an appetizer with toothpicks. Enjoy!
