    The Best Slow Cooker Tomato Basil Chicken Recipe

    Slow cooker tomato basil chicken has the perfect combination of creamy, tangy and savory flavors! The fire-roasted tomatoes and tomato sauce add a rich, slightly smoky depth to the dish, while the heavy cream balances it out and adds a velvety texture! The chicken will cook gently in the sauce and come out perfectly tender, too.

    Slow cooker meals are always great for busy weekdays. So when you need a comforting, easy home-cooked meal, this meal is ideal for you! It is versatile, family friendly, and so easy to make. Serve it with pasta and some crusty bread on the side and you have the perfect meal!

    Ingredients NEeded

    • Chicken Breasts: I like to use chicken breasts here, but you can use boneless, skinless chicken thighs if you prefer.
    • Fire Roasted Tomatoes: These add a deep, smoky flavor that elevates the sauce and adds a contrasting flavor to the creamy ingredients.
    • Tomato Sauce & Tomato Paste: The tomato sauce and paste along with the fire-roasted canned tomatoes provide a tangy, flavorful base.
    • Seasonings: I used Italian seasoning, garlic powder, and onion powder to season this dish to perfection!
    • Heavy Cream: Adds creaminess and smooths out the acidity of the tomatoes, creating a luscious sauce.
    • Cornstarch: To thicken up the sauce a bit!
    • Basil: For garnish!

    How to Make Tomato Basil Chicken in the Slow Cooker

    1. Place Ingredients in Slow Cooker: Add the fire roasted tomatoes, tomato sauce, Italian seasoning, garlic powder, onion powder and tomato paste to a slow cooker.
    2. Stir in Cornstarch Slurry: In a bowl combine the heavy cream and cornstarch. Whisk until no clumps remain. Add in the cornstarch cream mixture to the slow cooker with the rest of the ingredients and stir to combine.

    Tips for Success

    • Keep an eye on the chicken! When cooking chicken breasts, you have to make sure that they don’t get overcooked. If they are overcooked, they will be dry! Check the chicken for doneness around the 2 hour mark. If you aren’t sure, you can use a meat thermometer to make sure the internal temperature is at 165 degrees F. 
    • Don’t add cornstarch directly! It is important to whisk together the heavy cream and the cornstarch separately before adding it to the rest of the ingredients. This will ensure that the cornstarch will not clump up. 
    • If you like a slightly spicy sauce, add a few shakes of red pepper flakes into the sauce before cooking! Alternatively, you can sprinkle some red pepper flakes on top of the sauce after serving!

    Frequently Asked questions

    How should I serve slow cooker tomato basil chicken?

    I recommend serving this tomato basil chicken and sauce over a bed of your favorite pasta! For a low carb option, you can serve them with zucchini noodles instead. As a side dish, I recommend some cheesy garlic bread or garlic knots and a fresh Italian chopped salad!

    How long does this sauce last in the fridge?

    You can store any leftovers in an airtight container in the refrigerator for up to 4 days. The sauce may thicken slightly in the fridge, but it will loosen up once reheated.
