Prep the potatoes: Wash and dice the Yukon gold potatoes into roughly 1-inch pieces. No need to peel unless you prefer them that way.
Layer in the slow cooker: Add the diced potatoes to the bottom of the slow cooker in an even layer.
Add the chicken: Place the boneless skinless chicken breasts on top of the potatoes in a single layer as best you can.
Mix the sauce: In a small bowl, whisk together the condensed cream of chicken soup, chicken broth, and dry ranch seasoning mix until smooth.
Pour and coat: Pour the sauce evenly over the chicken and potatoes, making sure everything is lightly coated.
Cook: Cover and cook on LOW for 5–6 hours or on HIGH for 2.5–3.5 hours, until the chicken is cooked through (165°F internally) and the potatoes are tender when pierced with a fork.
Finish and serve: Taste and add a pinch of salt and pepper if needed. Serve the chicken breasts with a generous scoop of the potatoes and spoon some of the creamy sauce over the top.
Variations & Tips
To keep this as a true 5-ingredient recipe, I rely on pantry staples to do the heavy lifting, but there are plenty of easy ways to switch things up. If you prefer dark meat, boneless skinless chicken thighs work beautifully and stay extra juicy; just keep an eye on the cook time since they can be done a bit sooner. For a slightly lighter version, swap the cream of chicken soup for a 98% fat-free version or use cream of mushroom instead for a deeper, savory flavor. You can also change up the seasoning packet—Italian dressing mix gives it a herby, almost rotisserie-style vibe. If your slow cooker tends to run hot and you’re worried about dry chicken, check it 30–45 minutes earlier than the suggested time and switch to the “keep warm” setting once the chicken hits 165°F. For meal prep, portion the chicken and potatoes into containers with a handful of fresh spinach or green beans; when you reheat, the veggies will steam lightly and you’ve got a full lunch ready to go. And if you like things a little cheesier, you can stir in a small handful of shredded cheddar right at the end of cooking so it melts into the sauce without counting as one of the core ingredients.
