1 cup marinara sauce
3 cloves garlic, finely minced
1 teaspoon salt
1 teaspoon Italian seasoning
½ teaspoon dried basil
¼ teaspoon black pepper

How to Make Slow Cooker Creamy Tomato Basil Chicken Recipe

This recipe is wonderfully straightforward, which is exactly what busy days call for.

Step 1: Build the Sauce

In a 4- to 6-quart slow cooker, add the diced tomatoes (with all that flavorful juice), marinara sauce, garlic, salt, Italian seasoning, dried basil, and pepper. Give it a good stir so everything gets cozy together.

Step 2: Add the Creamy Magic

In a small bowl, whisk together the heavy cream and cornstarch until smooth. This little step makes all the difference—it’s what turns the sauce from “nice” into luxuriously creamy. Pour it into the slow cooker and stir gently.

Step 3: Nestle in the Chicken

Add the chicken breasts and press them down into the sauce so they’re fully coated. They’ll slowly soak up all that tomato-basil goodness as they cook.

Step 4: Let the Slow Cooker Do Its Thing

Cover and cook on low for 3 to 4 hours, until the chicken is tender and a meat thermometer reads 165°F at the thickest part. No babysitting required.

Step 5: Finish and Serve

Stir in the fresh basil, taste the sauce, and adjust the seasoning if needed. Serve warm with a generous sprinkle of grated Parmesan cheese. (Because Parmesan makes everything better.)

My Favorite Serving Ideas

One of the things I adore about Slow Cooker Creamy Tomato Basil Chicken is how flexible it is. Here are a few ways to serve it, depending on your mood:

Over pasta: Penne, fettuccine, or spaghetti soak up that sauce like a dream.
With rice: White rice, brown rice, or even cauliflower rice all work.
On mashed potatoes: Ultimate comfort food territory.
With crusty bread: For scooping up every last drop of sauce—non-negotiable.

Helpful Tips for Foolproof Results

Because even easy recipes deserve a few insider tricks:

Don’t rush it. Cooking on low keeps the chicken tender and juicy.
Sauce too thick? Add a splash of chicken broth or milk to loosen it up.
Sauce too thin? Let it sit uncovered for a few minutes, or stir gently—it thickens as it cools.
Want extra flavor? A pinch of red pepper flakes adds warmth without overwhelming the dish.
Short on time? You can cook on high for about 2 hours, but low-and-slow really shines here.

And if your sauce looks extra thick, don’t panic. That’s just comfort concentrating itself.
