Ingredients for Slow Cooker Tomato Basil Chicken Breast

• 1 (14-ounce) can diced tomatoes with Italian herbs, including the juice
• 1 cup marinara sauce
• 3 cloves garlic, finely minced
• 1 teaspoon salt
• 1 teaspoon Italian seasoning
• ½ teaspoon dried basil
• ¼ teaspoon black pepper
• ½ cup heavy whipping cream
• 2 tablespoons cornstarch
• 4 boneless, skinless chicken breasts (about 2 pounds)
• 2 tablespoons finely chopped fresh basil
• Grated Parmesan cheese, for serving

Step 1: Prepare the Sauce

In a mixing bowl, combine the diced tomatoes with their juice, marinara sauce, minced garlic, salt, Italian seasoning, dried basil, and black pepper. Stir until everything is evenly mixed.

Step 2: Add the Chicken

Arrange the chicken breasts in a single layer inside the slow cooker. Pour the prepared tomato sauce over the chicken, making sure each piece is well coated.

Step 3: Slow Cook

Cover the slow cooker with the lid and cook on Low for 5–6 hours or High for 2½–3 hours, until the chicken reaches an internal temperature of 165°F (74°C) and is tender.

Step 4: Make the Cream Sauce

Whisk together the heavy whipping cream and cornstarch until completely smooth. Pour the mixture into the slow cooker and gently stir it into the tomato sauce.

Step 5: Finish Cooking

Cover again and cook for an additional 15–20 minutes, allowing the sauce to thicken into a rich, creamy consistency.

Step 6: Garnish and Serve

Sprinkle with freshly chopped basil and grated Parmesan cheese before serving. Enjoy over pasta, rice, mashed potatoes, or with crusty bread.

Notes

• Chicken thighs can be substituted for chicken breasts if you prefer darker meat.
• Fresh basil adds the best flavor, but dried basil works in a pinch.
• If the sauce becomes thicker than desired, stir in a small amount of chicken broth.
• For extra richness, add additional Parmesan directly into the sauce.
• Use freshly grated Parmesan for the smoothest texture and best flavor.

Watch Out for These Mistakes While Cooking

• Overcooking the chicken can make it dry, even in the slow cooker.
• Don’t skip whisking the cream with the cornstarch first, or lumps may form.
• Avoid adding the cream at the beginning, as it can separate during long cooking.
• Resist opening the lid frequently, which slows down cooking.
• Don’t forget to season the sauce before serving, especially if using low-sodium tomatoes.
• Using frozen chicken may increase cooking time and release excess moisture.

Frequently Asked Questions

1. Can I use frozen chicken breasts?

Yes, but for food safety it’s recommended to thaw the chicken completely before placing it in the slow cooker. Using thawed chicken also helps it cook more evenly.

2. Can I substitute chicken thighs?

Absolutely. Boneless, skinless chicken thighs stay extra juicy during slow cooking and work just as well in this recipe.

3. Can I make this recipe dairy-free?

Yes. Replace the heavy whipping cream with a dairy-free cooking cream or full-fat coconut cream. Skip the Parmesan cheese or use a dairy-free alternative.

4. How do I know when the chicken is done?

The chicken is fully cooked when it reaches an internal temperature of 165°F (74°C) and is tender enough to slice or shred easily.

5. Can I shred the chicken instead of serving it whole?

Definitely! Shredded chicken mixes beautifully into the creamy tomato basil sauce, making it perfect for serving over pasta, rice, or even in sandwiches.

6. What pasta pairs best with this dish?

Fettuccine, penne, rigatoni, spaghetti, and linguine all pair wonderfully because they hold the creamy tomato sauce well.

7. Can I prepare everything ahead of time?

Yes. Combine the tomatoes, marinara, garlic, and seasonings in advance and refrigerate them separately. Add everything to the slow cooker when you’re ready to cook, then stir in the cream mixture near the end.

8. Can I add vegetables to the slow cooker?

Yes. Mushrooms, spinach, zucchini, bell peppers, or chopped onions are excellent additions that complement the tomato basil flavors.
