If there’s one recipe I’d return to again and again, it’s this Slow Cooker Creamy Tomato Basil Chicken. After making it last week, I couldn’t wait to share the slow cooker creamy tomato basil chicken recipe with you all! The chicken was so tender, the creamy tomato-basil sauce was downright addictive, and it required minimal effort.
It reminded me of the comforting flavors you’d expect from something like these chicken enchiladas with homemade red enchilada sauce, but with a completely unique twist. This recipe is versatile enough for a family dinner or a special occasion, and trust me, it will wow your taste buds.

Ingredients you Will Need
Here’s everything you’ll need to whip up this amazing dish, along with some tips to get it just right:
- Boneless skinless chicken breasts (4 pieces): These work perfectly since they cook evenly and remain juicy. If preferred, you can swap them for chicken thighs.
- Tomato pasta sauce (1 cup): Opt for a marinara-style sauce with bold, rich flavors for the best results.
- Canned diced tomatoes with Italian herbs (14 oz): Adds texture and depth; if you’re not a fan of tomato chunks, use an extra cup of pasta sauce instead.
- Minced garlic (2 teaspoons): Freshly minced garlic really enhances the flavor.
- Salt (1 teaspoon) and Italian seasoning (1 teaspoon): These spices tie everything together with a classic Mediterranean kick.
- Dried basil (½ teaspoon) and black pepper (¼ teaspoon): For a subtle yet essential seasoning.
- Heavy cream or evaporated milk (½ cup): Gives the sauce its creamy texture without curdling. Avoid low-fat options here.
- Corn starch (2 tablespoons): Helps to thicken the sauce beautifully.
- Fresh basil (2 tablespoons), finely chopped: The finishing touch for a fresh and aromatic flair.
Note: This recipe serves four people generously. Adjust the proportions if making it for more or fewer servings.
Variations to Try
You can customize this recipe to suit your dietary preferences or experiment with flavors:
- Dairy-Free Version: Use full-fat coconut cream instead of heavy cream for a subtle sweetness that pairs well with the tomato base.
- Spicy Twist: Add red pepper flakes for a kick of heat.
- Low-Carb Swap: Serve the chicken with spiralized zucchini noodles or cauliflower rice instead of pasta.
- Herb Alternatives: If fresh basil isn’t available, use basil pesto for an equally bright flavor.

How to Make Slow Cooker Creamy Tomato Basil Chicken
This recipe is straightforward, and the slow cooker does most of the work. Here’s how you can recreate the magic step by step:
Step 1 – Prepare the Base
Start by pouring the tomato pasta sauce and canned diced tomatoes into your slow cooker. Add the minced garlic, salt, Italian seasoning, dried basil, and black pepper. Stir everything thoroughly to create a flavorful base.
Step 2 – Whisk the Cream
Next, whisk together the heavy cream and corn starch in a mixing bowl until smooth. This mixture will give your sauce its creamy and luscious consistency. Add it to the slow cooker and gently stir to combine with the tomato base.
Step 3 – Add the Chicken
Place the chicken breasts into the slow cooker, ensuring they are well-coated with the sauce. Submerge them slightly for even cooking and better flavor absorption.
Step 4 – Cook to Perfection
Set your slow cooker to low for 3-4 hours or high for 2-2.5 hours. Check the internal temperature of the chicken toward the end of the cooking time to ensure it has reached 165°F.
Step 5 – Add Fresh Basil
Stir in the finely chopped fresh basil just before serving. This step adds a burst of freshness and rounds out the flavors beautifully.
Additional Tips for Making This Recipe Better
I’ve made this recipe multiple times, and here are some tips for making it even better:
- Don’t overcrowd the slow cooker. If the chicken is crammed together, it may not cook evenly.
- Use a high-quality marinara sauce for the best flavor. This truly makes a difference.
- Stir the sauce gently halfway through cooking to prevent any separation.
- Always use a meat thermometer to avoid overcooking the chicken.
- For an easier cleanup, consider using slow cooker liners.
