• 1 cup teriyaki sauce (bottled or homemade)
• 1/2 cup pineapple juice
• 1/4 cup brown sugar
• 1 tablespoon minced garlic
• 1 teaspoon fresh ginger, grated
• 1/2 teaspoon red pepper flakes (optional for a little heat)
• 1 tablespoon sesame oil
• Sesame seeds for garnish
• Sliced green onions for garnish

To make this recipe, you’ll want a 6-quart slow cooker and I also recommend using slow cooker liners for easy cleanup.

Now let’s break it down step by step…

How to Make Slow Cooker Teriyaki Meatballs

Place the frozen meatballs into the bottom of your slow cooker.

In a medium bowl, whisk together the teriyaki sauce, pineapple juice, brown sugar, minced garlic, grated ginger, sesame oil, and red pepper flakes until the sugar is dissolved.

Pour the sauce mixture over the meatballs and stir gently to ensure every meatball is well-coated.

Cover the slow cooker and cook on Low for 3 to 4 hours or on High for 1.5 to 2 hours, until the meatballs are hot all the way through.

Stir the meatballs once or twice during the cooking process if possible to redistribute the glaze.

Once finished, sprinkle the meatballs with sesame seeds and sliced green onions.

If sauce is thin at the end, stir in the cornstarch slurry and cook 15–30 minutes more to thicken.

Slow Cooker Tips

Keep meatballs uniform in size so they cook evenly; use a cookie scoop for speed and consistency. If you Frozen meatballs work best for this recipe because they hold their shape well during slow cooking.

If the sauce seems thin at the end of cooking, mix 1 teaspoon cornstarch with 1 tablespoon cold water and stir it into the slow cooker. Cook on HIGH for 10–15 minutes until the sauce thickens.

For extra flavor, add a splash of rice vinegar or a pinch of red pepper flakes for heat.

Keep the slow cooker on warm when serving at parties so the meatballs stay hot.

Serving and Storage Suggestions

Serve meatballs over steamed white or brown rice for an easy bowl meal. Toss cooked noodles with a bit of sesame oil and place meatballs and sauce on top for a noodle dinner.

For parties, transfer to a slow cooker on warm and provide toothpicks.

Garnish with sliced green onions and toasted sesame seeds. Leftovers keep well in the fridge for 3–4 days and freeze for up to 3 months; reheat gently to avoid drying out.

Best Dishes to Pair With

Teriyaki meatballs pair well with simple sides like steamed white rice, fried rice, or lo mein noodles. For a lighter option, serve them with stir-fried vegetables such as broccoli, bell peppers, or snap peas.

They also work great alongside other appetizers like buffalo wings, spinach artichoke dip, or crock pot little smokies for a party spread.

Creative Leftover Ideas

Leftover teriyaki meatballs can easily be turned into new meals. Serve them in rice bowls with vegetables, tuck them into slider buns for mini sandwiches, or slice them and add them to fried rice or noodle stir-fries.

How to Store and Reheat Leftovers

Allow the meatballs to cool slightly before storing them in an airtight container. Store sauce and meatballs together so the sauce keeps them moist.

Reheat on the stove over low heat, stirring occasionally, until warmed through and sauce bubbles gently. Add a splash of water or broth if the sauce has thickened too much.

You can also reheat in the oven at 325°F (160°C) covered with foil for 15–20 minutes, or in the microwave in short 30–45 second bursts, stirring between intervals to keep even heat.
