Ingredients You’ll Need

The best thing about this recipe is how straightforward the ingredients are. Each part works together to build that rich tomato and basil flavor you want, while keeping prep super simple. I always recommend grabbing the freshest basil you can find, but I’ll share a little secret if you’re out of season.

• Diced tomatoes with Italian herbs: Look for canned tomatoes with added Italian herbs to boost flavor without extra effort.
• Marinara sauce: I like to use a quality store-bought marinara for convenience; a more flavorful sauce means more flavor in the final dish.
• Garlic: Fresh and finely minced—garlic really wakes up the whole dish.
• Salt: Enhances all the flavors, just be sure to taste and adjust as you go.
• Italian seasoning: This blend keeps the herb profile balanced and familiar.
• Dried basil: Adds another layer of basil flavor along with the fresh later.
• Pepper: Just a pinch to round out the spices.
• Heavy whipping cream: The key to that silky, creamy texture that makes this dish so indulgent.
• Cornstarch: Helps thicken the sauce beautifully without needing extra flour or roux.
• Boneless skinless chicken breasts: I usually opt for breasts, but thighs can work if you want juicier meat.
• Fresh basil: Adds brightness and freshness right at the end—don’t skip it if you can help it!
• Parmesan cheese: Grated on top for that lovely salty finish and a bit of extra richness.

Variations

One of my favorite things about this recipe is how easy it is to make your own. Over time, I’ve tweaked it depending on what’s in my fridge or what my family is craving. Feel free to get creative with herbs, proteins, or even how creamy you want the sauce.

• Protein swaps: I’ve had great success swapping chicken breasts for boneless, skinless thighs when I want a richer taste and more tender texture.
• Spice it up: When I want a little heat, I add red pepper flakes right before serving—it perks things up without overwhelming the creaminess.
• Basil alternatives: Out of fresh basil? No worries! Stirring in a spoonful of basil pesto at the end is a lifesaver and still delivers that fresh-herby punch.
• Dairy-free: I’ve tried coconut cream as a substitute to keep it dairy-free; it changes the flavor profile but still results in a creamy sauce.

How to Make Creamy Tomato Basil Chicken in Slow Cooker Recipe

Step 1: Combine All the Saucy Goodness

Start by adding the diced tomatoes (with their Italian herb-filled juice), marinara sauce, minced garlic, salt, Italian seasoning, dried basil, and pepper right into your slow cooker. Give it a good stir to mix everything together evenly. This step is key because you want that sauce base to infuse the chicken with tons of flavor all day long.

Step 2: Whisk and Add the Cream Mixture

In a small bowl, whisk together the heavy whipping cream and cornstarch until fully combined—this little trick ensures that your sauce thickens up beautifully without lumps. Pour this creamy blend into the slow cooker and stir gently to incorporate with the tomato base.

Step 3: Add the Chicken and Slow Cook

Place the boneless skinless chicken breasts into the sauce, pressing them down a bit so they’re mostly submerged. This helps the chicken absorb all the flavors. Cover and cook on low for 3 to 4 hours. You’re aiming for a juicy chicken breast that hits an internal temperature of 165°F—tender but not dry. I learned that going too long can dry it out, so keep an eye on the time!

Step 4: Finish with Fresh Basil and Parmesan

Once the chicken is done, stir in the chopped fresh basil for a big burst of freshness. Give the sauce a taste, and adjust salt, pepper, or seasoning if needed. Serve with a generous sprinkle of grated Parmesan cheese and watch it disappear. I love pairing this with pasta because the sauce is perfect for soaking up those noodles.

How to Serve Creamy Tomato Basil Chicken in Slow Cooker Recipe

Garnishes

I’m a huge fan of topping this dish with freshly grated Parmesan and a sprinkle of extra fresh basil leaves. Sometimes I add a quick drizzle of good-quality olive oil or a few red pepper flakes for a bit of heat. It turns a simple meal into something that feels special without extra work.

Side Dishes

My go-to pairing is a bed of pasta, like spaghetti or penne, because the sauce clings so well and makes every bite delicious. Roasted vegetables or a simple green salad with lemon vinaigrette also complement the creamy tomato flavors perfectly if you want something lighter or gluten-free.

Creative Ways to Present

For dinner parties, I sometimes plate the chicken breasts over creamy polenta or risotto instead of pasta. It’s a stunning twist that impresses guests and feels upscale while still being comforting. Plating with a sprig of fresh basil and a Parmesan shaving really elevates the look.

Make Ahead and Storage

Storing Leftovers

I store leftovers in airtight containers in the fridge, and it keeps well for up to 3 days. The sauce thickens as it chills, so if it feels too thick when reheating, just add a splash of water or broth to loosen it up.

Freezing

This recipe freezes beautifully. I portion out the chicken and sauce into freezer-safe containers and thaw overnight in the fridge before reheating. Just a heads up—the cream sauce may separate slightly, but stirring during reheating brings it back to silky perfection.

Reheating

I prefer reheating gently on the stovetop over low heat, stirring often until warmed through, which helps maintain the creamy texture. Microwave works too, but I recommend stirring halfway through to keep the sauce even.
