There’s something comforting about a creamy tomato sauce simmering away in the slow cooker all afternoon. This Crock Pot Creamy Tomato Basil Chicken is one of those easy dinners that feels cozy and homemade without requiring much effort. The sauce is rich and creamy with plenty of garlic, herbs, and tomato flavor, and the chicken turns out tender enough to cut with a fork.

This is the kind of recipe that works on busy weeknights when you want something filling but don’t want to stand over the stove. Serve it over pasta, rice, or mashed potatoes to soak up all that creamy tomato sauce. A sprinkle of Parmesan and fresh basil at the end makes it taste like you spent way more time on dinner than you actually did.

Helpful Tips

- Test the internal temperature of the chicken to make sure you don’t overcook it. Smaller chicken breasts may not need 4 hours to cook through.
- Whisk the cream and cornstarch together until completely smooth before adding it to the slow cooker to avoid lumps in the sauce.
