Ingredients You’ll Need

The ingredients here are simple but thoughtfully combined to create a sauce that’s both flavorful and creamy. I recommend using good-quality canned tomatoes and fresh basil when you can — it makes a big difference in flavor.

• Diced tomatoes with Italian herbs: Using tomatoes already seasoned with herbs saves time and adds depth. I like San Marzano style for sweetness.
• Tomato pasta sauce: A good jarred sauce works fine; avoid anything too sweet or spicy to preserve balance.
• Minced garlic: Fresh is best if you have it, but jarred garlic works in a pinch.
• Salt: Enhances all the flavors in the dish — I usually go light and adjust later if needed.
• Italian seasoning: A classic blend that complements tomato and basil beautifully.
• Dried basil: Adds extra herbaceous notes; don’t skip it even if you have fresh basil later.
• Black pepper: A bit of spice to balance the creamy sauce.
• Evaporated milk or heavy cream: I prefer heavy cream for richness, but evaporated milk gives a lighter touch while still creamy.
• Corn starch: This is the secret to thickening the sauce without altering the flavor.
• Boneless skinless chicken breasts: They absorb the sauce perfectly and stay juicy when cooked low and slow.
• Fresh basil: Added at the end for that fresh, vibrant pop of green and flavor.

Variations

I love how flexible this Slow Cooker Creamy Tomato Basil Chicken Recipe is. Over time, I’ve tweaked it to suit our taste buds and the seasons, so feel free to experiment and make it truly yours.

• Spicy Kick: I sometimes add crushed red pepper flakes for a gentle heat that wakes up the creamy sauce. My family goes crazy for it with this twist.
• Leafy Greens: Toss in baby spinach or kale during the last 30 minutes for extra nutrition and color.
• Dairy-Free: Swap heavy cream for coconut milk and make sure your tomato sauce has no dairy — you’ll still get a creamy, dreamy sauce.
• Chicken Thighs: If you want juicier, more forgiving meat, bone-in thighs work great; just adjust the cooking time accordingly.

How to Make Slow Cooker Creamy Tomato Basil Chicken Recipe

Step 1: Layer the Tomato Base

Start by adding the diced tomatoes with Italian herbs, tomato pasta sauce, minced garlic, salt, Italian seasoning, dried basil, and black pepper into your slow cooker. Give everything a good stir to combine. This mix is aromatic already, and it forms the flavorful foundation for the whole dish — don’t skip the gentle stir so the seasonings distribute evenly.

Step 2: Whisk Cream and Corn Starch

In a separate bowl, whisk together the evaporated milk or heavy cream with the corn starch until smooth. This step is crucial for avoiding lumps and ensuring a silky thick sauce. Once combined, pour the mixture into the slow cooker and gently stir to blend it evenly with the tomato base.

Step 3: Add Chicken and Cook

Place the boneless skinless chicken breasts into the sauce, pressing them down slightly to cover them. Cover with the slow cooker lid and cook on low for 3 to 5 hours. Keep an eye on the time based on your slow cooker’s size — a fuller crock usually takes longer, while a smaller one might cook faster. Use a meat thermometer to check for 165°F to be sure your chicken is perfectly cooked.

Step 4: Stir in Fresh Basil and Serve

Once the chicken is cooked through, stir in the finely chopped fresh basil just before serving. This final step brings brightness and that amazing fresh aroma, giving the dish a vibrant lift that contrasts beautifully with the creamy tomato sauce.

How to Serve Slow Cooker Creamy Tomato Basil Chicken Recipe

Garnishes

I usually top this dish with an extra sprinkle of freshly chopped basil and a little grated Parmesan if I’m feeling indulgent. Sometimes I throw on a few fresh basil leaves whole — it just looks so pretty and adds a subtle herbal aroma right at the table.

Side Dishes

This creamy chicken pairs wonderfully with simple sides like buttery pasta, fluffy rice, or even creamy polenta. I’ve also served it alongside a crisp green salad and roasted veggies like asparagus or zucchini to balance the richness.

Creative Ways to Present

For special occasions, I like to plate the chicken over a nest of angel hair pasta with a drizzle of basil oil and a scattering of toasted pine nuts for extra crunch. It feels restaurant-worthy and always impresses guests without a ton of extra work.

Make Ahead and Storage

Storing Leftovers

Leftovers keep beautifully in an airtight container in the fridge for up to 3 days. I’ve found the flavors even deepen after a day, so it’s a fantastic make-ahead meal. Just make sure to cool before refrigerating to keep it fresh.

Freezing

I’ve frozen this Slow Cooker Creamy Tomato Basil Chicken Recipe a few times with no loss in flavor or texture. Freeze in portions in freezer-safe containers, then thaw in the fridge overnight before reheating gently. The sauce may separate slightly but just stir it back together.

Reheating

I reheat leftovers on the stovetop over low heat to gently warm without curdling the cream. Stir frequently and add a splash of water or broth if the sauce thickens too much. The chicken stays tender, and the sauce remains rich and velvety.
