This slow cooker 4-ingredient creamy pesto chicken is the kind of bright, savory dish my daughter asks for again and again. It reminds me of the church potlucks I grew up with here in the Midwest, where simple ingredients and a trusty slow cooker could turn an ordinary weeknight into something a little special. Tender chicken breasts simmer in jarred basil pesto and a splash of cream until they’re fall-apart soft, then get finished with a blanket of melted white cheese. It’s unfussy, comforting, and just fancy enough to feel like a small celebration at the end of a long day.
Serve this creamy pesto chicken spooned over hot buttered egg noodles, mashed potatoes, or plain white rice so all that pale green sauce has something to soak into. A simple green side—steamed broccoli, green beans, or a tossed salad with a tangy vinaigrette—keeps the plate fresh and balanced. Warm dinner rolls or a thick slice of crusty bread are wonderful for swiping up the extra sauce, and if you like a little color, a few halved cherry tomatoes on the side make a pretty, bright contrast.
Slow Cooker Creamy Pesto ChickenServings: 4
Ingredients
2 pounds boneless, skinless chicken breasts
1 cup prepared basil pesto (store-bought jar or homemade), divided
1 cup heavy cream or half-and-half
1 1/2 cups shredded mozzarella or other mild white cheese
Directions
Lightly spray the inside of your slow cooker with nonstick cooking spray or rub with a bit of oil to help with cleanup later.
Lay the boneless, skinless chicken breasts in a single layer in the bottom of the slow cooker. If they overlap a little, that’s fine, but try not to stack them too high.
In a small bowl, stir together 3/4 cup of the basil pesto and the heavy cream (or half-and-half) until the mixture is smooth and pale green.
Pour the creamy pesto mixture evenly over the chicken breasts, turning the pieces once or twice with a spoon or tongs so they’re well coated in the sauce.
Cover the slow cooker with the lid and cook on LOW for 3 1/2 to 4 1/2 hours, or on HIGH for about 2 to 3 hours, until the chicken is cooked through and very tender. The internal temperature should reach at least 165°F (74°C).
Once the chicken is done, use two forks to slice or thickly shred the chicken breasts right in the slow cooker, then gently stir so every piece is coated in the creamy pesto sauce.
Stir the remaining 1/4 cup basil pesto into the sauce for a fresh, bright flavor boost. Taste and add a pinch of salt or pepper if needed.
Sprinkle the shredded mozzarella (or other white cheese) evenly over the top of the saucy chicken. Cover the slow cooker again and let it sit on LOW or the WARM setting for 10 to 15 minutes, just until the cheese is melted and gooey.
Serve the creamy pesto chicken hot, spooning the sliced or shredded chicken and plenty of the pale green sauce onto plates, then topping each serving with some of the melted cheese from the top of the slow cooker.
Variations & Tips
For a slightly lighter version, you can use half-and-half in place of heavy cream, though the sauce will be a bit thinner. If you’d like more tang, stir in a spoonful of grated Parmesan (in addition to the mozzarella) when you add the last bit of pesto. Any mild white melting cheese works nicely—Monterey Jack, provolone, or an Italian blend will all give you that stretchy, comforting top layer. You can also swap boneless, skinless chicken thighs for the breasts; they stay very moist and are more forgiving if cooked a little longer. If using frozen chicken, always thaw it completely in the refrigerator before adding it to the slow cooker to ensure even cooking and food safety; starting with frozen chicken in the slow cooker can keep the meat at unsafe temperatures too long. Use a meat thermometer to confirm the chicken reaches 165°F (74°C) in the thickest part. Refrigerate leftovers within 2 hours of cooking, and reheat gently on the stovetop or in the microwave until steaming hot, adding a splash of cream or milk if the sauce has thickened too much.
