Slow Cooker Sweet Teriyaki Chicken Thighs

This is the set-it-and-forget-it dinner that delivers big flavor with almost no effort. Six chicken thighs, a pile of sweet Vidalia onions, and a generous pour of teriyaki glaze go into the slow cooker, then walk away.

Hours later, the chicken is pull-apart tender, the onions have melted into sweet ribbons, and the sauce has thickened into a glossy caramelized coating. Serve it over steamed jasmine rice for a weeknight meal that feels like a treat.

The beauty of this recipe is its simplicity. You don't need to brown the chicken, sauté the onions, or stand over the stove. The slow cooker does all the work, turning humble ingredients into a deeply savory-sweet dish with a sticky, caramelized finish.

The key is using boneless skinless chicken thighs, which stay moist and tender during the long cook, and sweet Vidalia onions that break down into silky strands. The teriyaki glaze reduces slightly as it simmers, concentrating its flavor into a rich sauce that clings to every bite.

Ingredients

Why this recipe works

Chicken thighs are the right choice here. They have enough fat and connective tissue to stay juicy and tender through hours of slow cooking, unlike chicken breasts which can turn dry and stringy. As they cook, the thighs become so tender that they shred easily with a fork, soaking up the teriyaki glaze like a sponge. The result is deeply flavorful, melt-in-your-mouth chicken that needs no extra work.

Vidalia onions are another key player. These sweet onions are low in sulfur, so they caramelize into soft, sweet ribbons without turning bitter. As they cook low and slow, they release their natural sugars into the sauce, balancing the salty-sweet teriyaki glaze and adding a subtle depth that you won't get from regular yellow onions. The onions essentially melt into the sauce, creating a rich, cohesive dish.

Notes and substitutions

Teriyaki glaze is thicker than standard teriyaki sauce, which helps it cling to the chicken and create that shiny, caramelized finish. Look for a bottle labeled 'glaze' or 'teriyaki glaze' in the international aisle.

If you only have regular teriyaki sauce, you can simmer it on the stovetop for a few minutes to reduce and thicken it, or add a teaspoon of cornstarch mixed with water to help it coat.

This recipe is endlessly adaptable. Swap the chicken thighs for boneless skinless chicken breasts, but reduce the cook time to 3-4 hours on low to avoid drying them out. For a spicier version, add a teaspoon of sriracha or red pepper flakes to the glaze.

To make it gluten-free, use a gluten-free teriyaki glaze and check that your sesame seeds are certified gluten-free. For a lower-sodium option, use a reduced-sodium teriyaki glaze.

• Vidalia onions: Any sweet onion, such as Walla Walla or Maui, or use yellow onions for a slightly sharper flavor.
• Teriyaki glaze: Use a thicker teriyaki sauce or homemade teriyaki glaze (soy sauce, mirin, sugar, and ginger).
• Boneless skinless chicken thighs: Bone-in chicken thighs work, but increase cook time to 4-5 hours on low and remove bones before serving.
• Toasted sesame seeds: Black sesame seeds or omit for a nut-free garnish.
