This hearty slow cooker creamy tomato basil chicken has become my go-to dinner solution on busy weeknights. The magic happens when tender chicken simmers in a rich tomato sauce that transforms into a velvety dream with just a splash of cream.
I first discovered this recipe during a particularly chaotic month when my family needed comforting meals but I had zero time to stand over the stove. The delicious aroma that filled our home convinced me that slow cooker meals could truly rival anything made with more complicated techniques.

Step-by-Step Instructions
- Base Sauce Preparation:
- Add your diced tomatoes pasta sauce garlic salt Italian seasoning dried basil and pepper to the slow cooker. Mix these ingredients thoroughly to create a flavorful foundation that will infuse into the chicken during cooking. The combination of dried and fresh herbs creates layers of flavor that develop beautifully over time.
- Create The Creamy Element:
- Whisk together the evaporated milk or heavy cream with cornstarch until completely smooth with no lumps. This mixture will thicken your sauce without forming clumps. Pour this into your tomato base and give everything a good stir to incorporate it evenly throughout the sauce.
- Add The Protein:
- Place your chicken breasts into the sauce mixture making sure to press them down so they're fully submerged. This ensures even cooking and allows the chicken to absorb all those wonderful flavors from every direction.
- Slow Cooking Magic:
- Cover and cook on low heat for 3-5 hours until the chicken reaches 165 degrees F on a meat thermometer. Cooking low and slow allows the proteins in the chicken to break down gently resulting in incredibly tender meat that practically falls apart when touched with a fork.
- Final Fresh Touch:
- Just before serving stir in the freshly chopped basil. This last-minute addition brings a burst of color and fresh flavor that complements the long-cooked sauce perfectly. The heat from the dish will release the essential oils in the basil for maximum aroma.

My family particularly loves the way the sauce clings to pasta creating the perfect bite every time. My daughter who normally picks around tomato chunks in other dishes happily devours this one declaring it "restaurant fancy" which is the highest praise from a picky preteen.
Storage Tips
This creamy tomato basil chicken keeps beautifully in the refrigerator for up to 4 days in an airtight container. The flavors actually continue to develop making it sometimes even better on day two. For freezing transfer cooled portions to freezer-safe containers leaving about half an inch of space at the top to allow for expansion. Freeze for up to 3 months. Thaw overnight in the refrigerator before gently reheating on the stovetop or microwave adding a splash of cream if needed to revive the sauce.
Make It Your Own
This recipe welcomes adaptation based on what you have available. Boneless chicken thighs make an excellent substitute offering even more moisture and flavor. For a vegetarian version replace the chicken with chickpeas or white beans and vegetable broth. If you enjoy heat a pinch of red pepper flakes or cayenne pepper adds a wonderful warming element without overwhelming the dish. During winter months when fresh basil is scarce substitute with a tablespoon of prepared basil pesto stirred in at the end for that same bright flavor profile.
Serving Suggestions
While this chicken is delicious simply served over pasta consider some creative serving options to keep meals interesting throughout the week. Spoon it over creamy polenta for a comforting Italian-inspired dish. Use it as a filling for twice-baked potatoes topped with a sprinkle of mozzarella cheese. For a lighter option serve the chicken and sauce over roasted spaghetti squash or zucchini noodles. The versatility of this recipe means you can transform one cooking session into several distinctly different meals.
