Ingredients & Why Each One Matters
- 2 pounds bone-in, skinless chicken thighs – Chicken thighs are ideal for slow cooking because they stay moist and become incredibly tender. The bone adds extra depth of flavor to the cooking liquid.
- 1 large yellow onion, thinly sliced – As the onions cook slowly, they soften and release natural sweetness, creating a flavorful base and silky texture for the sauce.
- 1 cup chicken broth (low-sodium preferred) – This adds moisture and richness, helping create a savory sauce while preventing the chicken from drying out.
- 1 packet dry onion soup mix or chicken seasoning blend – This single ingredient brings layers of seasoning, salt, and umami, making the recipe incredibly flavorful with no extra work.
Step-by-Step Instructions
-
Prepare the slow cooker:
Lightly spray the inside of your slow cooker with nonstick cooking spray or rub it with a small amount of oil. This helps prevent sticking and makes cleanup easier. -
Layer the onions:
Spread the sliced onions evenly across the bottom of the slow cooker. This creates a flavorful bed for the chicken and keeps it from sticking to the bottom. -
Season the chicken:
Pat the chicken thighs dry with paper towels. Sprinkle the dry onion soup mix or seasoning blend evenly over all sides of the chicken, pressing gently so it adheres well. -
Add chicken and broth:
Place the seasoned chicken thighs on top of the onions in a single layer if possible. Carefully pour the chicken broth around the chicken, not directly over it, to avoid washing off the seasoning. -
Slow cook to perfection:
Cover with the lid and cook on LOW for 6–7 hours, or until the chicken is very tender and easily pulls away from the bone. For a faster option, cook on HIGH for 3–4 hours, though low and slow gives the best results. -
Taste and adjust:
Once cooked, taste the cooking liquid. Add a pinch of salt or pepper if needed, then gently stir the onions and juices around the chicken. -
Serve:
Carefully remove the chicken thighs using tongs—they will be very tender. Spoon the soft onions and flavorful juices over the chicken and serve hot.

- For extra richness: Add a small pat of butter on top of the chicken before cooking.
- For a creamy finish: Stir in sour cream or Greek yogurt at the end on WARM setting.
