Ingredients

Why this recipe works

The slow cooker's low, steady heat breaks down the collagen in chicken thighs, making them exceptionally tender and juicy. Unlike chicken breasts, thighs stay moist even after hours of cooking, so they absorb the teriyaki glaze without drying out.

The long cooking time also allows the flavors of the peppers, onion, and sauce to meld together into a cohesive, savory-sweet dish.

Cooking everything in one pot means the chicken and vegetables simmer in the same glaze, so every bite is infused with the same rich flavor.

The natural juices from the chicken and vegetables mix with the teriyaki sauce, creating a glossy, thick sauce that clings to each piece. This method is foolproof and requires minimal hands-on time, making it ideal for busy cooks.

Notes and substitutions

Choose boneless, skinless chicken thighs for the best texture; they are more forgiving than breasts and become incredibly tender. If using chicken breasts, reduce the cooking time to about 2 hours on low to avoid dryness. The bell peppers and onion add sweetness and color, so use a mix of red, yellow, and green for a vibrant presentation.

Teriyaki glaze is thicker than traditional teriyaki sauce, which helps it coat the ingredients and caramelize slightly during cooking. If you only have teriyaki sauce, add a tablespoon of honey or brown sugar to thicken it.

Toasted sesame seeds add a nutty aroma and a pleasant crunch; toast them in a dry skillet for a minute until fragrant if using untoasted seeds.

• chicken thighs: Chicken breasts can be used, but they may dry out; reduce cooking time to about 2 hours on low.
