Ingredients

Why this recipe works

The slow cooker is a master of transforming simple ingredients into something deeply flavorful. Cooking the chicken low and slow keeps it moist and tender, while the pasta shells cook in the sauce, absorbing the smoky red pepper flavor as they soften.

The cream cheese and mozzarella melt into the sauce, creating a rich, velvety texture that clings to every bite. Because everything cooks together in one pot, the flavors meld and intensify, resulting in a dish that tastes far more complex than its ingredient list suggests.

This recipe is designed for convenience without sacrificing taste. By layering the ingredients in the order they are added, the pasta stays submerged in the sauce, ensuring it cooks evenly without turning mushy.

The cream cheese and mozzarella melt slowly, creating a smooth, cohesive sauce rather than a greasy mess. The result is a hearty, satisfying meal that requires almost no hands-on time, making it ideal for anyone who wants a home-cooked dinner without the hassle.

Notes and substitutions

For the best results, use a 7-quart slow cooker to give the ingredients room to cook evenly. If using a smaller slow cooker, reduce the quantities proportionally. The pasta shells need enough liquid to soften, so make sure the sauce covers them as much as possible.

If the sauce seems too thick, add a splash of chicken broth before cooking. The cream cheese should be softened to room temperature before adding, so it melts more smoothly into the sauce.

This recipe calls for smoky roasted red bell pepper cream sauce, which is available in many grocery stores or can be made at home. If using a store-bought version, look for one without added sugar or heavy cream. The whole-milk mozzarella shreds better and melts more smoothly than part-skim, but part-skim will also work. For a spicier kick, add a pinch of red pepper flakes or a dash of hot sauce to the sauce before cooking.

• boneless skinless chicken breasts: boneless skinless chicken thighs, cut into bite-sized cubes (cook the same way; thighs stay moist and tender)
• medium conchiglie pasta shells: other short pasta shapes like penne, rigatoni, or fusilli (adjust cooking time as needed)
• smoky roasted red bell pepper cream sauce: store-bought roasted red pepper pasta sauce mixed with 1/2 cup heavy cream for a similar smoky, creamy flavor
• whole-milk mozzarella: part-skim mozzarella or a blend of Italian cheeses (shredded fresh mozzarella also works, but may be more watery)
