- 1 can (8 ounces) tomato sauce

- Use low sodium if your canned tomatoes taste salty.
- 4 ounces cream cheese, softened and cubed
- Full fat melts smoother, but reduced fat still works.

- Keep the lid on the slow cooker as much as possible so the heat stays consistent.
- Add dairy near the end of cooking so the sauce stays smooth and creamy.
- Taste the sauce at the end and adjust salt, pepper, and sugar so the tomato flavor tastes balanced.

How to Make Slow Cooker Creamy Tomato Basil Chicken Recipe
Step 1: Prep the slow cooker base
Add crushed tomatoes, tomato sauce, and chicken broth to the slow cooker. Stir in garlic, onion, sugar, salt, pepper, dried basil, dried oregano, dried thyme, and crushed red pepper flakes. Mix until everything looks combined and the spices spread evenly through the tomato mixture.
Step 2: Add the chicken
Nestle the chicken breasts into the tomato mixture in a single layer as much as possible. Spoon a little sauce over the top of each piece so they all sit coated. Cover the slow cooker with the lid.
Step 3: Cook the chicken
Cook on low for 4 to 6 hours or on high for 2½ to 3½ hours. Check at the earlier time mark, since slow cookers run differently. The chicken finishes when it feels very tender and reaches 165°F in the thickest part.
Step 4: Add the creamy elements
Transfer the chicken to a plate and tent it loosely with foil or a lid. Add the cream cheese cubes to the hot tomato sauce in the slow cooker. Whisk or stir until the cream cheese melts and blends into the sauce.
Step 5: Finish the sauce
Pour in the heavy cream or half and half and whisk again until the sauce looks smooth and silky. Stir in the Parmesan cheese until it melts. Taste and adjust seasoning with more salt, pepper, or a pinch of sugar if the tomatoes taste sharp.
Step 6: Add the chicken back
Slice or shred the cooked chicken, depending on how you want to serve it. Return the chicken to the slow cooker and stir so the pieces soak in the creamy tomato basil sauce. Sprinkle in the fresh basil and stir again, saving a little for garnish if you like.
Step 7: Serve
Spoon the Slow Cooker Creamy Tomato Basil Chicken over hot pasta, rice, or mashed potatoes. Top with extra Parmesan and more fresh basil. Serve right away while the sauce tastes hot and creamy.
What to Serve with Slow Cooker Creamy Tomato Basil Chicken Recipe
Serve this Slow Cooker Creamy Tomato Basil Chicken Recipe over penne, rotini, or spaghetti for a cozy pasta night. Pair it with a simple green salad, garlic bread, or warm crusty rolls to soak up the extra sauce. Steamed broccoli, green beans, or roasted zucchini balance the richness nicely. A side of fluffy white rice, brown rice, or cauliflower rice also works well when you want a gluten free option.
Storage Options
- Store leftovers in an airtight container in the fridge for 3 to 4 days.
- Reheat gently on the stove over low heat, and add a splash of milk or broth if the sauce thickens too much.
- Reheat in the microwave in short bursts, stirring between each burst so the sauce heats evenly.
- Freeze in freezer safe containers for up to 2 months, then thaw overnight in the fridge before reheating.
