Why we love this Slow Cooker Chicken Breast recipe:

  • it’s a Real Life recipe: it’s easy to prep, mostly hands off and the family loves. We all need more of that!
  • it’s a slow cooker win: with a lot of slow cooker recipes, I find you sacrifice either flavor or texture or both. With this chicken you dump and go, and the sauce is the perfect consistency when it’s done and the flavor is awesome!
  • it’s quick to prep: being a dump and go slow cooker, you don’t need to spend hours in the kitchen, which is a plus on busy weeknights!

Slow Cooker Tomato Basil Chicken Ingredients:

ingredients needed for slow cooker tomato basil chicken.
  • Chicken breasts: we always use chicken breasts for this recipe but boneless, skinless chicken thighs would also work well. If you choose bone-in chicken the cook time will increase significantly.
  • Tomato pasta sauce: this is simply a tomato sauce that you would use on pasta with herbs and seasonings, i.e., a marinara or something similar. This is not tomato paste. Choose your favorite well-seasoned brand!
  • Diced tomatoes: If you don’t like the chunks of tomato you can sub this out with an additional cup of tomato pasta sauce.
  • Garlic and seasonings: I’ve kept things simple, but feel free to experiment if you prefer. Add some red pepper flakes if you like things spicy!
  • Cream: I recommend heavy cream or evaporated milk in this recipe. I find that they have the lowest chance of curdling when cooked with the acidic tomatoes. I do not recommend low fat cream or milk, but you are always welcome to try!
  • Corn starch: A little corn starch helps to thicken our sauce. You can swap this out with flour if you don’t have any.
  • Fresh basil: fresh basil can be hard to find in the cooler months. Basil pesto is my favorite swap because it adds more of that fresh flavor than dried basil.

How to make Creamy Tomato Basil Crockpot Chicken Breast:

This is a simple overview to help guide you! Scroll down to find the detailed recipe in the pink recipe card.

  • Stir together sauce, tomatoes and herbs.
  • Whisk the corn starch into the cream.
  • Add the cream to the slow cooker and stir.
  • Add the uncooked chicken and cook until the internal temperature reaches 165 degrees F.

How long to cook chicken breasts in the crockpot?

Not overcooking slow cooker chicken breasts is the key to having juicy and flavorful chicken.

I usually recommend 3 hours on low — this might be a little less if your chicken breasts are small or a little more if your chicken breasts are large.

If you’re cooking on high, check the internal temperature at 2-2.5 hours and add time as needed.

Can I use half and half or milk?

Low fat dairy has more of a tendency to curdle.

For that reason, the addition of the tomatoes and the long cook time, I prefer not to take the chance. My exception is low fat evaporated milk, which I find works really well in slow cooker recipes.

You are always welcome to try it!

What kind of tomato pasta sauce do I need?

Choose your favorite brand of tomato-based pasta sauce, i.e., marinara sauce or something similar.

You’re looking for a relatively smooth and well-seasoned tomato sauce, rather than a can of plan crushed tomatoes.

Tips for making this slow cooker chicken recipe:

  • Don’t overcook it — I find 3 hours is plenty for the usual size of my chicken breasts. I recommend checking the temperature at 2.5 hours for smaller breasts, and 3 hours for larger breasts, and adding time as needed.
  • I made this recipe in a 4 quart slow cooker — if you want to double it, I suggest a 6 quart slow cooker (I have both, and use them for different things!).
  • I really, really love using slow cooker liners. I will gladly pay the 50 cents or whatever they cost to not have to wash that beast!
  • Please always, always check the temperature of your chicken with a meat thermometer before serving just to be safe! All slow cookers cook differently.

Servings 4
Calories 210cal


  • 14 oz can diced tomatoes with Italian herbs (398 ml)
  • 1 cup tomato pasta sauce
  • 2 teaspoons minced garlic
  • 1 teaspoon salt
  • 1 teaspoon Italian seasoning
  • ½ teaspoon dried basil
  • ¼ teaspoon black pepper
  • ½ cup evaporated milk or heavy cream
  • 2 tablespoons corn starch
  • 4 boneless skinless chicken breasts
  • 2 tablespoons finely chopped fresh basil


  • Add tomatoes, pasta sauce, garlic, salt, Italian seasoning, basil and pepper to a 3-6 quart slow cooker. Stir.
  • Whisk together cream and corn starch and add to the slow cooker.
  • Add chicken breasts and press down into the sauce.
  • Cook on low for 3-5 hours, until a meat thermometer reads 165 degrees F. The exact cook time will depend on your slow cooker — a fuller slow cooker will take longer to cook, so a larger one will cook faster.
  • Stir in fresh basil and serve over pasta, rice, or with a salad and veggies!


*Some sauce was removed from the pictures in the slow cooker to show detail. The recipe makes plenty of sauce for pasta!
Ingredients and Substitutions:
Chicken: this recipe will also work with boneless, skinless chicken thighs, or try it with chicken meatballs, sausages, or another cut for something unique!
Tomato pasta sauce: choose any tomato marinara-style sauce you like. The more flavor in the pasta sauce, the more flavor your chicken will have. 
Diced tomatoes: if you don’t like the chunks of diced tomatoes, I recommend just swapping with additional tomato sauce.
Cream or evaporated milk: Heavy cream or evaporated milk will work best because they do not curdle. Please do not use regular milk or a light cream. 
Herbs & seasonings: feel free to adjust the herbs and seasonings to your tastes. Like it spicy? Add some cayenne or red pepper flakes!
Fresh basil: we make this recipe all year round but fresh basil can be impossible to find. I like to swap with basil pesto for that fresh basil flavor.

    This is so easy and delicious! I added some home grown tomatoes from the yard and they really added to the flavor. Thank you for this recipe.

    • The Recipe Rebel says

      Hi Nick! You could either try reheating in a pan on the stovetop or in the microwave. If using a microwave I would reduce the power and watch your time so you don’t dry out your chicken.

  2. Bron says

    It’s very easy to make. It taste nice but needs a little ‘something’. Will work on it. Great base though. Will make it again.

    • Ashley Fehr says

      The overall flavor will definitely depend on the flavor of the sauce and tomatoes. I love using a roasted garlic or fire roasted tomato sauce for extra oomph 🙂

  3. Lisa says

    Hi, I have the Ninja foodi and I haven’t tried the slow cooker function yet. This looks delicious. Would you be able to tell me the conversion to a pressure cooked preparation?

  4. Toni says

    This is a family favourite. Very easy to make, can be done when in a rush by just putting everything into the slow cooker and leaving it to do its work.

  5. Irene says

    Absolutely AMAZING! chicken melts in your mouth. The flavors are amazing too! Tastes almost like a tomato Basil bisque sauce. Highly recommend

  6. Laura says

    I read the reviews that said it was bland, so I made sure to use extra seasonings. I tossed spaghetti noodles with olive oil and more seasonings, and put the chicken on top. I also made cheesy garlic bread (kinda like grilled cheese with tomato soup!). I thought it was AMAZING. Very light but also yummy. Definitely different, but in a good way. My 15yo loved it too. He even commented that the tomatoes were really good. My 12yo is the biggest fan of grilled cheese with tomato soup, so I figured he would love it, but he said it was partially bland and partially bad flavors. Not sure what happened there, but he wouldn’t eat his. More for me!!!

    • Ashley Fehr says

      Thanks for sharing Laura! The amount of seasonings required will definitely depend on the type of tomatoes and sauce that is used. I always use tomatoes with Italian herbs and seasoned pasta sauce, but there’s lots of room for customizing!

  7. ABC says

    Tried this and my whole family loved it. I followed the recipe exactly and everything was just delicious.

  8. Tauren says

    This was very bland. Honestly confused about all the good reviews. was not good at all. 0 stars.

    • The Recipe Rebel says

      Sorry to hear you didn’t enjoy the recipe Tauren. Myself (and others) have enjoyed and wished it would of been a hit with you. We all have different taste, so you should definitely adjust the seasoning based on your needs.

  9. Stephanie says

    This is absolutely fantastic!! A real hit! I am so glad I found your site. Thank for sharing your amazing talent!! I can’t wait to try other recipes.

    • The Recipe Rebel says

      Hi! I don’t actually calculate macros and actually have no knowledge of macros. The nutritional information is calculated automatically in the recipe card. When in doubt you should always use any free online resource that calculates nutritional information.

  10. C. says

    It’s one of my favorite meals! It’s easy and tasty. At the end of my meal I just want to lick the plate. Soooo good!!

  11. Noni says

    Hi, when using pasta sauce would I use like a jarred already seasoned sauce like Prego or just the unseasoned can of like hunts tomato sauce

    • Em says

      Hi, I’ve made this dish a few times and I’ve always used seasoned sauce from the jar. Today I used Rao’s Arrabbiata sauce, which has a little kick to it. Excited to see how it turns out!

    • Molly says

      I’ve always used a jarred sauce like Prego. I think unseasoned tomato sauce would lack flavor and be a little bitter.

  12. Angie Gettis says

    Just made this chicken dish. It was so easy! And the taste is so good! I’ve tasted so far. Waiting for everyone to get here so we can eat! Next time I make this I’ll double recipe and let it slow cook all day!

    • The Recipe Rebel says

      Hi Liza, I haven’t tried this in the instant pot before, but I do have a stove top version coming next Wednesday, so watch out for that one to post!

  13. Sheila says

    I’m making this for our dinner tomorrow. This will be my fourth time making it. It’s super delicious!!!! I serve ours over thin spaghetti. Definitely a favorite!!!

  14. Jordan says

    If I doubled the recipe do you think I could leave it on low for the day while I’m at work or will it dry the recipe out/over cook? New job, full time working mumma now so trying to sort my life out 😅

    • The Recipe Rebel says

      Hi Jordan! I’ve only tested the recipe as written, so I wouldn’t be able to advise how that would work. If you decide to experiment, let me know how it goes!

    • Sarah says

      I doubled the recipe and honestly it only takes about 6-7 hours to cook untill it is done, I forgot about about it and left it for 8 and nothing seemed dry just that the chicken fell apart on me which isn’t a big deal still super amazing
