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:

• 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 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.
