Cooking Instructions
Here’s how to create this delightful slow cooker meal:
1. Prepare the Base: Begin extract by adding the can of diced tomatoes with their juice to your slow cooker. Don’t drain them; the liquid is packed with flavor and will contribute to the sauce. Next, pour in the cup of marinara sauce. This layered tomato base will form the foundation of our flavorful sauce. Now, add the finely minced garlic. Using fresh garlic really makes a difference here, as it infuses the sauce with a lovely pungent aroma and taste as it cooks. Stir in the salt, Italian seasoning, dried basil, and pepper. Give everything a good stir to combine these dry seasonings with the tomato mixtures. This ensures the flavors are evenly distributed throughout the slow cooker from the very begin extractning.
2. Add the Chicken: Place the four boneless, skinless chicken breasts into the slow cooker, nestling them into the tomato mixture. Try to arrange them so they are mostly submerged in the sauce. This will help them cook evenly and become incredibly tender. If your chicken breasts are particularly thick, you might consider gently pressing them down slightly to encourage even cooking. Don’t worry too much about perfection here; the slow cooker is quite forgiving.
3. Slow Cook to Perfection: Cover the slow cooker and set it to cook on low for 4-6 hours, or on high for 2-3 hours. The exact cooking time will depend on the size and thickness of your chicken breasts and your specific slow cooker model. The goal is for the chicken to be cooked through and incredibly tender, easily shreddable with a fork. I usually check for doneness around the 4-hour mark on low, especially if the chicken breasts are on the smaller side. It’s better to err on the side of caution and cook it a little longer to ensure it’s perfectly tender rather than undercooked.
4. Create the Creamy Finish: Once the chicken is cooked through and tender, carefully remove the chicken breasts from the slow cooker and set them aside on a plate. In a small bowl, whisk together the heavy whipping cream and the cornstarch until there are no lumps and the mixture is smooth. This cornstarch slurry will act as a thickener for our sauce. Pour this creamy mixture directly into the slow cooker with the tomato sauce. Stir well to combine. Place the lid back on the slow cooker and cook on high for another 15-20 minutes, or until the sauce has thickened to your desired consistency. Stir occasionally during this thickening phase to prevent any sticking at the bottom. The sauce should become glossy and rich.
5. Finish and Serve: While the sauce is thickening, you can shred or dice the chicken breasts that you removed earlier. I prefer to shred mine for a more rustic feel, but dicing works beautifully too. Once the sauce has thickened, return the shredded or diced chicken to the slow cooker and stir it into the creamy tomato sauce. Gently stir in the finely chopped fresh basil. The fresh basil adds a burst of bright, herbaceous flavor that complements the cooked sauce perfectly. Allow the chicken to heat through in the sauce for about 5-10 minutes. Serve the Slow Cooker Creamy Tomato Basil Chicken hot, generously spooned over your favorite starch or alongside crusty bread. Don’t forget to top each serving with grated Parmesan cheese for an extra layer of savory goodness. Enjoy this comforting and delicious meal!

Frequently Asked Questions:
Can I use chicken breasts instead of thighs?
Absolutely! You can certainly use boneless, skinless chicken breasts. However, chicken breasts tend to cook faster and can become dry if overcooked. I recommend reducing the slow cooker time to about 2-3 hours on low, or until the chicken is cooked through. It’s always best to check the internal temperature to ensure it reaches 165°F (74°C).
What if I don’t have heavy cream?
If you don’t have heavy cream on hand, you have a few good alternatives. You can use half-and-half, though the sauce might be slightly less rich. Another option is to use evaporated milk. For a dairy-free version, consider using full-fat canned coconut milk (just the solid cream part) or a dairy-free creamer alternative. Stir it in during the last 30 minutes of cooking.
Can I freeze leftovers?
Yes, leftovers of this Slow Cooker Creamy Tomato Basil Chicken freeze very well! Once completely cooled, portion the chicken and sauce into airtight containers or freezer bags. It should keep for up to 3 months in the freezer. Thaw overnight in the refrigerator and reheat gently on the stovetop or in the microwave.
