Ingredients

1 can diced tomatoes with Italian herbs, with juice (14 oz)
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-by-Step Instructions

Preparing the Ingredients

Start by lightly spraying the slow cooker insert with nonstick spray. Mince the garlic and chop the fresh basil so everything is ready to go. Measure the seasonings, cream, and cornstarch ahead of time. This quick prep step makes the rest of the recipe feel effortless and keeps the process smooth from start to finish.

Cooking Instructions

Add the diced tomatoes, marinara sauce, garlic, salt, Italian seasoning, dried basil, and pepper to the slow cooker, then stir until well combined. In a small bowl, whisk together the heavy cream and cornstarch until smooth, then pour it into the sauce. Nestle the chicken breasts into the mixture, pressing them down so they are mostly covered. Cover and cook on low for 3 to 4 hours, until the chicken reaches an internal temperature of 165°F. Stir in the fresh basil just before serving and finish with grated Parmesan.

Tips for Perfect Results

Common Mistakes to Avoid

Avoid lifting the lid during cooking, since heat loss increases cook time and affects texture. Do not substitute regular milk for heavy cream, because it can separate and change the sauce consistency. Also, resist overcooking the chicken, as slow cookers vary and chicken breasts can dry out if left too long.

Pro Tips for Better Flavor

For deeper flavor, use a high-quality marinara sauce with bold seasoning. If you prefer extra richness, add a little more cream near the end of cooking. This recipe also works well as Crockpot Creamy Chicken when served over pasta, where the sauce clings beautifully to every bite.

Serving and Storage

How to Serve

Serve Slow Cooker Tomato Basil Chicken over pasta, rice, or mashed potatoes to soak up the sauce. Roasted vegetables or a crisp green salad balance the richness well. For a lighter option, spoon the chicken and sauce over zucchini noodles or steamed cauliflower for a Healthy Slow Cooker dinner that still feels comforting.

How to Store Leftovers

Store leftovers in an airtight container in the refrigerator for up to three days. Reheat gently on the stovetop or in the microwave until warmed through. Add a splash of cream or water if the sauce thickens during storage.

Conclusion

Slow Cooker Tomato Basil Chicken proves that simple ingredients and smart cooking can still deliver big results. This recipe fits perfectly into busy schedules while offering comforting flavor and flexibility.
