Cooking Instructions
1. Prepare the Chicken and Sauce Base: Before we get anything into the slow cooker, it’s a good idea to prepare your chicken. I like to trim any excess fat from the chicken breasts, although this is optional. Patting the chicken dry with paper towels can help it brown slightly if you choose to sear it beforehand (though it’s not strictly necessary for this slow cooker recipe). Now, let’s create the flavor base. In your slow cooker insert, add the can of diced tomatoes with their juice, the cup of marinara sauce, and the finely minced garlic. Stir these together to combine. This forms the foundation of our delicious sauce.
2. Season the Sauce and Add Chicken: Next, it’s time to bring in those essential seasonings that will elevate the tomato base. Add the teaspoon of salt, the teaspoon of Italian seasoning, the half teaspoon of dried basil, and the quarter teaspoon of pepper to the tomato mixture. Stir everything well to ensure the seasonings are evenly distributed. Now, place your four boneless, skinless chicken breasts directly into the slow cooker, nesting them into the sauce mixture. You want the chicken to be mostly submerged in the liquid for even cooking.
3. Slow Cook for Tenderness: Cover the slow cooker with its lid and set it to cook on LOW for 4-5 hours, or on HIGH for 2-3 hours. The exact cooking time will depend on your slow cooker model and the thickness of your chicken breasts. The goal is for the chicken to be completely cooked through and incredibly tender. You’ll know it’s ready when it easily shreds with a fork. I usually opt for the LOW setting as it tends to yield more tender results and provides more flexibility in cooking time, which is one of the beauties of slow cooking. Avoid the temptation to lift the lid too often during cooking, as this can release precious heat and extend the cooking time.
4. Create the Creamy Element: Once the chicken is cooked and tender, it’s time to transform the sauce into its creamy, luxurious state. Remove the cooked chicken breasts from the slow cooker and set them aside on a plate. In a small bowl, whisk together the half cup of heavy whipping cream and the two tablespoons of cornstarch until you have a smooth slurry. This cornstarch slurry is the key to thickening our sauce without any lumps. Slowly pour this mixture into the liquid remaining in the slow cooker.
5. Thicken the Sauce and Reincorporate Chicken: Stir the cornstarch slurry into the tomato sauce in the slow cooker. Once combined, turn the slow cooker to the HIGH setting (if it wasn’t already) and cook for another 15-30 minutes, uncovered, stirring occasionally, until the sauce has thickened to your desired consistency. It should be rich and luscious. While the sauce is thickening, you can shred the chicken breasts with two forks or cut them into bite-sized pieces. Once the sauce is perfectly thickened, return the shredded or cut chicken to the slow cooker and stir it into the creamy tomato basil sauce. Allow it to simmer for a few more minutes to warm the chicken through.
6. Final Touches and Serving: Just before serving, stir in the two tablespoons of finely chopped fresh basil. The fresh basil adds a vibrant, aromatic finish that really brightens up the entire dish. Taste the sauce and adjust salt and pepper if needed. Serve this delightful Slow Cooker Creamy Tomato Basil Chicken over your favorite pasta, rice, or even mashed potatoes. It’s also fantastic served with crusty bread for soaking up every last drop of that amazing sauce. Don’t forget to top each serving with a generous sprinkle of grated Parmesan cheese – it’s the perfect salty, nutty finish to this incredibly satisfying meal. Enjoy!

I love serving this creamy chicken over fluffy rice, pasta, or even with some crusty bread for dipping.

If you’re feeling adventurous, try swapping out the chicken for thighs for an even more decadent texture, or add a pinch of red pepper flakes for a touch of heat. I truly hope you give this Slow Cooker Creamy Tomato Basil Chicken a try soon. I’m confident it will become a regular in your rotation!
Frequently Asked Questions:
Can I use frozen chicken for this recipe?
Yes, you can! If using frozen chicken breasts or thighs, you can place them directly into the slow cooker. However, they may take a little longer to cook through, so be sure to check the internal temperature to ensure it reaches 165°F (74°C) before serving. It’s always best to ensure it’s fully cooked.
What if I don’t have fresh basil?
No problem at all! You can substitute dried basil for fresh. A good rule of thumb is to use about one-third of the amount of dried basil compared to fresh. So, if the recipe calls for 1/2 cup of fresh basil, use about 2 tablespoons of dried basil. Add it in with the other dried herbs and spices earlier in the cooking process for the best flavor infusion.
Can I make this recipe dairy-free?
Absolutely! To make this dairy-free, you can replace the heavy cream with full-fat coconut milk (from a can) or a dairy-free creamer alternative. You might need to adjust the seasoning slightly to achieve your desired richness and flavor profile. The tomato flavor will still shine through beautifully!
