Instructions

Prepare cream mixture: In the slow cooker insert, whisk together the heavy cream and cornstarch until fully combined to ensure a smooth, thickening base for the sauce.
Add tomato ingredients: Stir in the tomato paste, canned diced tomatoes, cherry tomatoes, minced garlic, dried basil, dried thyme, sea salt, and black pepper. Mix well to evenly distribute all ingredients and create a flavorful sauce.
Place chicken in slow cooker: Add the chicken breasts to the slow cooker, gently pressing them down slightly so they are submerged and coated with the tomato cream sauce.
Cook: Cover with the lid and cook on HIGH for 3 hours or on LOW for 10 hours, allowing the chicken to cook through and the sauce to thicken and meld flavors.
Serve: Once done, optionally garnish with fresh basil leaves and serve hot with your choice of sides such as rice, pasta, or crusty bread.

Notes

This dish is full of rich, comforting flavors and uses simple, wholesome ingredients you likely already have on hand.
Cooking on LOW for 10 hours yields extra tender chicken with even more developed flavors.
Fresh basil as a garnish brightens the creamy tomato sauce with freshness.
If you don’t have cherry tomatoes, adding extra canned diced tomatoes works just as well.
