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.

  • 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.

Total Time 4 hours 5 minutes
Cuisine American
Course Main Course
Servings 4
Calories 210cal

Ingredients

  • 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

Instructions

  • 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!

Notes

*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.

    Quick, easy, and very good. We especially liked the creamy sauce. Before serving I added some freshly grated parmesan with a bit of fresh basil; served with salad, roasted broccoli, and bread. Delicious!

  2. Vanessa says

    I am sure you know whether or not you can put aluminum foil over the top of the chicken loosely and add potatoes or rice or vegetables on top of that aluminum foil has this been done I’m sure it has. Thank you for your reply.

    This was delicious! And I love that it was a dump, set, and forget recipe. No cutting required! (Except for fresh basil at the end.) I doubled the recipe and following it exactly. I did find the sauce to be too runny for my liking. It was like soup, not thick like Alfredo, which is my preference. So I just made a quick roux on the side and whisked it into the sauce to get the thicker consistency. Not sure if it was just watery for me because extra water in the chicken breast? This is only the second time I’ve used my slow cooker. Love this recipe! Will be adding it to my favorites. Thank you!

    Made this today. Followed the recipe exactly other than combo chicken breasts & chicken thighs. Winter in Wisconsin so no fresh basil, but used basil pesto (strained to eliminate the oil). Perfect Recipe! Loved! Will definitely make again. I wasn’t sure at the store whether or not to purchase evaporated milk or heavy cream … seemed like evaporated milk was artificial so opted for heavy whipping cream … perfect … no curdling & great consistency with the sauce. Served it over a small bed of Ziti Rigatoni. My husband & I both loved it! Will definitely make again. GREAT FIND! It’s often times difficult to find a truly winning online recipe. Thank you Ashley! I look forward to perusing your other recipes!

    Is it supposed to be a 28 oz can of diced tomatoes? The can in the video looks bigger than a 14oz can. I used a 14oz can per the ingredients and my sauce looks less red than the video. Thanks!

    I made this recipe, and it was delicious. Instead of doing it in the slow cooker
    I made it on the stove, browning the chicken first, then adding the rest of
    the ingredients. I added half and half cream instead of evaporated milk.
    I added it just in the last few minutes, heating only, not bringing to boil.
    It worked great.

  7. Erika says

    This was delicious. It tasted like something I would order at a restaurant. I will definitely be making this again.
