These tender chicken thighs are slow-cooked to perfection in a rich and creamy pesto and ranch sauce. The combination of basil pesto, ranch seasoning, chicken broth, heavy cream, and Parmesan creates a flavorful sauce that infuses the meat while cooking gently in a slow cooker. Perfect for an easy, comforting meal, this dish pairs well with steamed rice, mashed potatoes, or roasted vegetables. Garnishing with fresh basil and extra Parmesan adds a finishing touch of freshness and depth.
My sister texted me at 7pm on a Tuesday, completely frazzled after a brutal day at work, begging for something that would basically cook itself. I threw this combination together on impulse, having no idea if pesto and ranch would actually be friends in the same pot. She called me two hours later from her couch, half-asleep and utterly in love with what happened in that slow cooker.
Last winter, my neighbor smelled this cooking through our shared apartment wall and actually knocked on my door to investigate. Now she makes it every Sunday for meal prep, and Ive started doing the same because theres nothing quite like opening the fridge to find leftover chicken in that sauce.
Ingredients
- 8 boneless skinless chicken thighs: Thighs stay impossibly tender during long cooking, whereas breasts would turn into something closer to sadness than dinner
- 1/2 cup basil pesto: Store-bought works perfectly fine, but if you have access to fresh summer basil, homemade pesto makes this sing a different song entirely
- 1 packet ranch seasoning mix: This is the shortcut that pulls everything together into something familiar and comforting
- 1/2 cup chicken broth: Use whatever you have in the pantry, even if its just water with better than bouillon mixed in
- 1/2 cup heavy cream: Half-and-half works if youre watching calories, though the sauce wont be quite as luxurious
- 2 tablespoons grated Parmesan cheese: Sprinkle this right into the sauce, not on top, so it melts into the cream and creates tiny salty pockets throughout
- Fresh basil leaves and extra Parmesan: These are completely optional but make everything look intentional when you serve it
Instructions
- Arrange the chicken:
- Lay the thighs in your slow cooker, letting them overlap slightly if needed but trying to keep everything relatively even so they cook at the same pace
- Mix the sauce:
- Whisk the pesto, ranch packet, broth, cream, and Parmesan in a bowl until you cant see any white cream streaks anymore
- Pour and cover:
- Drizzle that green-flecked sauce all over the chicken, put the lid on, and walk away like you just accomplished something enormous
- Cook on low:
- Let it go for 4 to 6 hours, checking that the chicken reaches 165°F in the thickest part if youre the type who owns a meat thermometer
- Serve it up:
- Transfer everything to a platter, spoon that gorgeous sauce over the top, and scatter some fresh basil around so it looks like you tried harder than you actually did
My now-husband admitted on our third date that he thought this chicken took me hours to prepare, which I cleverly did not correct until months later. Sometimes the easiest meals make the biggest impressions.
Serving Suggestions That Actually Work
The sauce is rich enough to stand up to plain steamed rice, which is honestly what I serve most often when I want something filling but not complicated. Mashed potatoes soak up that pesto cream like they were born for it, creating these little flavor pockets in every bite. Roasted vegetables add some needed brightness and crunch to balance how tender everything else becomes.
Make Ahead Magic
You can assemble everything the night before and keep the slow cooker insert in the fridge, which means dinner is literally ready to start with the push of one button in the morning. The chicken actually gets better as it sits in that sauce, so leftovers arent just acceptable, theyre arguably improved. I portion mine into glass containers and have genuinely looked forward to cold lunches straight from the fridge.
Customization Ideas
Sometimes I add sun-dried tomatoes to the sauce for extra tang and these chewy little bursts that surprise you in every few bites. A handful of spinach stirred in during the last hour wilts down into something silky and makes me feel like Im eating something slightly more virtuous.
- Mozzarella cheese melted on top creates this incredible bubbly crust that my kids fight over
- Garlic powder or fresh minced garlic takes the ranch flavor to a place that feels more homemade
- Red pepper flakes add just enough heat to cut through all that cream if you like things with a little kick
Good food doesnt have to be complicated, and sometimes the best dinners are just a few pantry ingredients and a little bit of faith.
