Ingredients

Tomato Sauce Base

  • 1 can diced tomatoes with Italian herbs with juice (14 oz or 398 ml)
  • 1 cup marinara sauce
  • 3 cloves garlic, finely minced
  • 1 teaspoon salt
  • 1 teaspoon Italian seasoning
  • ½ teaspoon dried basil
  • ¼ teaspoon pepper

Cream Mixture

  • ½ cup heavy whipping cream
  • 2 tablespoons cornstarch

Chicken

  • 4 boneless skinless chicken breasts (about 2 lbs)

Finishing Touches

  • 2 tablespoons finely chopped fresh basil
  • Grated Parmesan cheese, for serving

Instructions

  1. Prepare Sauce Base: Add the diced tomatoes with Italian herbs and their juice, marinara sauce, minced garlic, salt, Italian seasoning, dried basil, and pepper into a 4- to 6-quart slow cooker. Stir these ingredients together thoroughly to combine the flavors.
  2. Mix Cream and Cornstarch: In a small bowl, whisk together the heavy whipping cream and cornstarch until smooth and well combined. This mixture will help thicken the sauce during cooking.
  3. Add Cream Mixture to Slow Cooker: Pour the cream and cornstarch mixture into the slow cooker with the tomato sauce base, stirring gently to incorporate.
  4. Place Chicken in Sauce: Add the boneless skinless chicken breasts into the slow cooker, pressing them down slightly so they are coated and submerged in the sauce.
  5. Cook on Low: Cover the slow cooker and cook on low heat for 3 to 4 hours. The chicken is done when a meat thermometer inserted into the thickest part reads 165°F (74°C).
  6. Finish and Serve: Once cooked, stir in the freshly chopped basil. Taste the sauce and adjust seasoning as desired. Serve the chicken topped with grated Parmesan cheese for added richness and flavor.

Notes

  • You can substitute heavy cream with half-and-half for a lighter sauce, but it may be less thick.
  • For best results, do not open the slow cooker lid during cooking to maintain temperature and cooking time.
  • Serve with pasta, rice, or crusty bread to soak up the creamy tomato basil sauce.
  • Leftovers keep well in the refrigerator for 3 days and reheat gently on the stovetop or microwave.
