How to Make Slow Cooker Creamy Tomato Basil Chicken Recipe

Step 1: Layer the base flavors

Start by adding the diced tomatoes with their juices, marinara sauce, minced garlic, salt, Italian seasoning, dried basil, and pepper right into your slow cooker. Give everything a good stir to combine these fundamentals—the tomato herbs and spices will mingle and start releasing their magic as the chicken cooks.

Step 2: Mix the cream and cornstarch

In a small bowl, whisk together the heavy whipping cream and cornstarch. This little mixture is your secret weapon for that luscious, silky sauce. Pour it over the tomato mixture in the slow cooker, ensuring it’s well incorporated for smooth consistency.

Step 3: Add the chicken

Place your chicken breasts directly into the sauce, pushing them down gently so they’re fully nestled and soaking up all those incredible flavors. This simple step ensures each bite will be moist and infused with the creamy tomato basil sauce.

Step 4: Cook low and slow

Set your slow cooker on low and let the dish work its magic for 3 hours. You’re looking for the chicken to be tender and juicy, hitting an internal temperature of 165°F. This long, slow cooking is what makes the chicken absorb every ounce of cream and herb goodness.

Step 5: Finish with fresh basil and Parmesan

Once done, stir in the finely chopped fresh basil to brighten every bite with a fragrant punch. Taste your sauce and adjust the seasoning if needed. Serve the chicken warm, topped with a generous sprinkle of grated Parmesan to add that irresistible salty crunch.

FAQs

Can I use chicken thighs instead of chicken breasts?

Absolutely! Chicken thighs work wonderfully in this Slow Cooker Creamy Tomato Basil Chicken Recipe because they stay juicy and tender during slow cooking. Just adjust cooking time if needed to ensure tenderness.

Is it possible to make this recipe dairy-free?

Yes, you can substitute the heavy whipping cream with coconut cream or a non-dairy cream alternative. Just keep in mind this will slightly alter the flavor but you'll still get a creamy, delicious result.

Can I add vegetables to the slow cooker?

Definitely! Adding sliced bell peppers, mushrooms, or zucchini at the start can boost nutrition and flavor. Just be cautious with watery vegetables so they don’t dilute the sauce too much.

How thick should the sauce be? Can I make it thicker?

The sauce should be creamy and slightly thickened thanks to the cornstarch and cream. If you want a thicker sauce, you can mix a little more cornstarch with cold water and stir it in near the end of cooking, then cook a few minutes longer.

What’s the best way to serve leftovers?

Leftovers are fantastic over freshly cooked pasta or rice. You can also shred the chicken and use it as a filling for wraps or sandwiches with some fresh veggies for a quick, tasty lunch.
