Cooking Instructions:
1. Prepare the Chicken and Base: Begin extract by placing the boneless, skinless chicken breasts into the bottom of your slow cooker. Aim for a single layer if possible, though it’s not absolutely critical as the chicken will shrink as it cooks. Next, open your can of diced tomatoes with Italian herbs and pour the entire contents, including the juice, over the chicken. This juice is packed with flavor and will form the foundation of our sauce. Then, add the cup of marinara sauce. If you have a favorite brand of marinara, feel free to use that, as it will contribute its own unique flavor profile to the dish. Finally, add the finely minced garlic to the slow cooker. Ensure the garlic is spread evenly over the chicken and tomato mixture.
2. Seasoning and Flavor Infusion: Now it’s time to layer in the seasonings that will bring this dish to life. Sprinkle the teaspoon of salt evenly over the ingredients. This salt will enhance all the other flavors and prevent the dish from tasting bland. Next, add the teaspoon of Italian seasoning. This blend typically includes oregano, basil, thyme, rosemary, and marjoram, offering a complex herbal profile that complements the tomato and basil beautifully. Follow this with the ½ teaspoon of dried basil. While we’ll be adding fresh basil later for a vibrant finish, dried basil provides a deeper, more concentrated basil flavor that melds into the sauce as it cooks. Lastly, season with ¼ teaspoon of pepper. You can adjust the salt and pepper to your personal preference. Stir everything gently to distribute the seasonings, making sure the chicken is somewhat coated.
3. Slow Cooking for Tenderness: Cover your slow cooker with its lid, ensuring a good seal. Set your slow cooker to the LOW setting for 6 to 8 hours, or on the HIGH setting for 3 to 4 hours. The exact cooking time will depend on your specific slow cooker model and the thickness of your chicken breasts. The goal is for the chicken to be cooked through and incredibly tender, easily shredded with a fork. Cooking on low for a longer period tends to yield the most tender results, allowing the flavors to deepen and meld more effectively. Avoid the temptation to lift the lid frequently, as this releases heat and can extend the cooking time.
4. Creating the Creamy Sauce: Once the chicken is cooked and tender, carefully remove the chicken breasts from the slow cooker and place them on a plate. They will be very soft. Using two forks, shred the chicken into bite-sized pieces. While the chicken rests, we’ll thicken the sauce. In a small bowl, whisk together the ½ cup of heavy whipping cream and the 2 tablespoons of cornstarch until completely smooth. This mixture is often referred to as a slurry. It’s important to ensure there are no lumps of cornstarch, as this can lead to a lumpy sauce. Once the slurry is smooth, pour it into the slow cooker with the tomato mixture. Stir well to combine the cornstarch mixture with the existing liquid in the slow cooker.
5. Reuniting and Finishing Touches: Return the shredded chicken to the slow cooker. Stir the shredded chicken into the creamy tomato sauce, ensuring all the pieces are well-coated. At this point, you have a couple of options for the final stage. You can either turn the slow cooker to the WARM setting for about 15-30 minutes to allow the sauce to thicken further and for the flavors to meld with the chicken, or if you prefer a thicker sauce and have time, you can transfer the sauce and chicken to a saucepan and simmer gently on the stovetop over medium-low heat for about 5-10 minutes, stirring occasionally, until the sauce has reached your desired consistency. Finally, stir in the 2 tablespoons of finely chopped fresh basil just before serving. Fresh basil adds a burst of bright, herbaceous flavor that really elevates the dish. Serve this delicious Creamy Tomato Basil Chicken hot, garnished generously with grated Parmesan cheese. It’s a simple yet elegant meal that’s sure to become a family favorite. Enjoy!

Frequently Asked Questions:
Can I use chicken thighs instead of chicken breasts?
Absolutely! Chicken thighs work wonderfully in this recipe. They tend to stay even more tender and moist in the slow cooker. Just be aware that cooking times might vary slightly, so check for doneness before serving.
What kind of tomatoes should I use?
I recommend using crushed tomatoes for the sauce base, as they provide a great texture. Diced tomatoes would also work, but the sauce might be a bit chunkier. Ensure they are good quality for the best flavor.
How can I make this recipe dairy-free?
To make this dairy-free, you can swap the heavy cream for full-fat coconut milk or a dairy-free creamer. Be sure to choose an unsweetened variety to maintain the savory profile of the dish.
