Season and make the gravy
- Season the chicken thighs with salt, pepper, and onion powder, coating all sides evenly. Aim for full coverage so the flavor goes right to the meat.
- Whisk cream of mushroom soup, chicken broth, ranch seasoning mix, garlic, and dried thyme together until combined and smooth. This creates the creamy gravy base that will cook with the chicken.
Slow-cook
- Place the chicken thighs in the slow cooker and pour the gravy mixture over them. Make sure the thighs are mostly covered.
- Cook on Low for 5–6 hours until fall-apart tender, or on High for 2.5–3 hours, with the gravy visibly bubbling around the edges. Check doneness by testing if the meat pulls apart easily.
Finish and serve
- Remove the chicken from the slow cooker and stir the sour cream into the gravy until smooth. The sauce should turn glossy and creamy with no streaks.
- Return the chicken to the slow cooker briefly to coat, then serve over mashed potatoes with fresh parsley on top. Spoon extra creamy gravy over the potatoes so it pools at the base.
Notes
For the creamiest texture, stir the sour cream into the gravy off the heat if your slow cooker runs very hot—then return the chicken just to warm. Refrigerate leftovers in a covered container up to 3–4 days; reheat gently to avoid thinning. Freezing is not ideal because sour cream-based gravy can separate after thawing, but you can freeze chicken separately and re-make the gravy. For a lower-fat swap, use light sour cream instead of regular sour cream.
