How to Make Slow Cooker Creamy Tomato Basil Chicken Recipe
Step 1: Prepare the Chicken Base
Start by placing your chicken breasts in the slow cooker. This creates the foundation for your meal, ensuring every morsel becomes infused with the luxurious sauce that will blanket them later.
Step 2: Mix the Tomato Basil Sauce
In a medium bowl, blend together diced tomatoes, tomato sauce, heavy cream, chicken broth, Parmesan cheese, finely chopped onion, minced garlic, dried basil, dried oregano, salt, black pepper, and red pepper flakes if using. This mixture is where all the delicious flavor begins to develop—make sure it’s well combined to create a cohesive sauce for your chicken.
Step 3: Combine and Cook
Pour the vibrant tomato and cream mixture evenly over the chicken breasts in the slow cooker. Cover the cooker with its lid, and set it to cook on low for 4 to 6 hours. This slow, gentle heat tenderizes the chicken while letting all the wonderful flavors mingle and intensify.
Step 4: Blend the Sauce (Optional)
Once the chicken is cooked through and tender, carefully remove it from the slow cooker and set aside. Use an immersion blender right in the slow cooker to blend the sauce until smooth, if you prefer a silky texture. This step transforms the chunky sauce into a velvety, spoon-worthy accompaniment.
Step 5: Return Chicken and Finish
Place the chicken breasts back into the slow cooker and gently stir so the creamy tomato basil sauce coats every piece. This final step ensures the chicken stays juicy and fully enveloped in flavor.
How to Serve Slow Cooker Creamy Tomato Basil Chicken Recipe

Garnishes
Finishing off the dish with freshly chopped basil leaves adds a burst of vibrant green color and bright herbal notes that contrast beautifully with the creamy, red sauce. Sprinkle a little extra Parmesan cheese on top for an appetizing melt and slight tang.
Side Dishes
This Slow Cooker Creamy Tomato Basil Chicken Recipe pairs wonderfully with simple sides like fluffy rice, creamy mashed potatoes, or even al dente pasta. A side of sautéed green beans or a crisp garden salad rounds out the meal perfectly by adding freshness and crunch.
Creative Ways to Present
For a charming presentation, serve the chicken over polenta for a smooth, comforting base that soaks up the sauce. Alternatively, pile it on toasted ciabatta for an open-faced sandwich, garnished with a drizzle of balsamic glaze to add a touch of sweet acidity.
Make Ahead and Storage
Storing Leftovers
Place any leftover Slow Cooker Creamy Tomato Basil Chicken Recipe in an airtight container and refrigerate for up to 3 days. The flavors actually deepen overnight, so leftovers can be even more delicious!
Freezing
This dish freezes well, making it perfect for meal prep. Store individual portions in freezer-safe containers or heavy-duty freezer bags for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
Gently reheat leftovers on the stovetop over low heat to prevent the cream from separating, stirring occasionally until warmed through. If using a microwave, heat in short intervals, stirring in between to keep the sauce smooth and creamy.
FAQs
Can I use chicken thighs instead of breasts?
Absolutely! Chicken thighs will add even more juiciness and flavor. Just adjust the cooking time slightly, as thighs may take a bit longer to become tender.
Is it necessary to blend the sauce?
Not at all. Blending is optional—if you prefer a chunkier texture with bits of tomato and onion, you can skip this step for a rustic feel.
Can I make this recipe dairy-free?
You can swap the heavy cream for coconut milk or a creamy non-dairy alternative, and substitute Parmesan with a dairy-free cheese or nutritional yeast for a similar savory boost.
How spicy is this dish?
The crushed red pepper flakes add just a subtle hint of heat, which you can easily omit or increase based on your spice preference.
What is the best way to serve this for a family dinner?
Serving it over a bed of pasta or rice with fresh veggies on the side keeps it simple and satisfying for everyone, including picky eaters who appreciate familiar flavors.
