The creamy texture is achieved with heavy whipping cream and cornstarch, creating a comforting and easy meal perfect for busy days.

Ingredients

Chicken and Sauce

  • 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
  • 4 boneless skinless chicken breasts (about 2 lbs)

Cream Base

  • ½ cup heavy whipping cream
  • 2 tablespoons cornstarch

Garnish

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

Instructions

  1. Prepare the sauce: Add the diced tomatoes with Italian herbs, marinara sauce, finely minced garlic, salt, Italian seasoning, dried basil, and pepper to a 4- to 6-quart slow cooker. Stir the mixture well to combine all the flavors evenly.
  2. Mix cream and cornstarch: In a small bowl, whisk together the heavy whipping cream and cornstarch until smooth. This mixture will thicken the sauce during cooking.
  3. Add cream mixture and chicken: Pour the cream and cornstarch mixture into the slow cooker with the tomato sauce. Add the boneless skinless chicken breasts and press them down gently into the sauce to ensure they are submerged.
  4. Slow cook the chicken: Cover the slow cooker and cook on low for 3 to 4 hours. The chicken is done when a meat thermometer inserted into the thickest part reads 165°F (74°C), ensuring it is fully cooked and tender.
  5. Finish and serve: Stir in the freshly chopped basil leaves, then taste the sauce and adjust the seasoning if needed. Serve the chicken topped with grated Parmesan cheese for added flavor and richness.

Notes

  • Use fresh basil for garnish to brighten the dish just before serving.
  • For a thicker sauce, you can add an additional tablespoon of cornstarch mixed with water before cooking.
  • Pair this dish with pasta, rice, or crusty bread to soak up the creamy tomato sauce.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
