Ingredients You’ll Need
To create this Slow Cooker Creamy Tomato Basil Chicken Recipe, you only need a handful of simple, staple ingredients, each playing a crucial role in building layers of flavor, creating a smooth texture, and even adding a pop of color that makes the dish inviting even before the first bite.
- 4 boneless, skinless chicken breasts: The main protein providing tenderness and a great base to soak up the creamy sauce.
- 1 (14 oz) can diced tomatoes: Fresh-tasting and juicy, these add bright acidity and texture.
- 1 (14 oz) can tomato sauce: Creates the rich, velvety foundation for the sauce.
- 1 cup heavy cream: Offers luxurious creaminess that balances the tomato’s acidity perfectly.
- 1/2 cup chicken broth: Enhances the savory depth and keeps the sauce moist.
- 1/4 cup grated Parmesan cheese: Adds nutty, umami-rich flavor for complexity.
- 1 medium onion, finely chopped: Builds aromatic sweetness that melts into the sauce.
- 4 cloves garlic, minced: Provides a punch of pungent, warming undertones.
- 1 teaspoon dried basil: Infuses that signature herbaceous note integral to the recipe.
- 1 teaspoon dried oregano: Gives rustic depth and a subtle earthiness.
- 1/2 teaspoon salt: Enhances all the flavors seasoning the chicken and sauce.
- 1/4 teaspoon black pepper: Adds mild heat and sharpness against the creamy backdrop.
- 1/4 teaspoon crushed red pepper flakes (optional): For just a touch of exciting, gentle heat to brighten the dish.
- Fresh basil leaves, chopped (for garnish): Provides fresh aroma and a vibrant green color that makes the dish pop.
How to Make Slow Cooker Creamy Tomato Basil Chicken Recipe
Step 1: Prepare the Chicken Base
Start by placing those lovely boneless, skinless chicken breasts directly into your slow cooker. This setup allows them to soak in flavors and remain juicy while cooking slowly throughout the day.
Step 2: Combine the Sauce Ingredients
Next, grab a medium bowl and mix together the diced tomatoes, tomato sauce, heavy cream, chicken broth, Parmesan cheese, finely chopped onion, minced garlic, dried basil, dried oregano, salt, black pepper, and crushed red pepper flakes if you want a hint of spice. Make sure everything is well blended to create a harmonious sauce that marries creamy richness with herbaceous, tangy notes.
Step 3: Pour Over Chicken
Pour this luscious tomato cream mixture evenly over the chicken breasts in the slow cooker. It’s like tucking the chicken into a warm, flavorful blanket that will transform into a creamy sauce by the time it’s done.
Step 4: Cook Low and Slow
Cover your slow cooker and set it to cook on low for 4 to 6 hours. This slow cooking time ensures the chicken becomes melt-in-your-mouth tender, while the flavors meld beautifully, creating that unforgettable creaminess you’re aiming for.
Step 5: Blend the Sauce (Optional)
Once the chicken is cooked through, remove the breasts and place them aside temporarily. Then, if you prefer a silky smooth sauce, use an immersion blender directly in the slow cooker to blend the sauce until it reaches your desired consistency. This step really elevates the dish’s texture.
Step 6: Return Chicken and Coat
Finally, nestle the chicken breasts back into the sauce and gently stir to coat them evenly. The chicken will absorb even more of that sumptuous sauce, making each bite incredibly flavorful and moist.
Step 7: Garnish and Serve
Sprinkle freshly chopped basil leaves on top to add brightness and freshness right before serving. This simple addition takes the dish to the next level, both visually and flavor-wise.

Garnishes
Fresh basil leaves are a must for garnishing, as they bring an aromatic, herbal pop that complements the creamy tomato undertones perfectly. For a little extra flair, you can also sprinkle some additional Parmesan cheese or a drizzle of high-quality olive oil to shine a luscious gleam on top.
Side Dishes
This dish pairs beautifully with a variety of sides. Creamy mashed potatoes or buttery polenta make a wonderful comforting base to soak up the sauce. For a lighter option, steamed green beans, sautéed spinach, or a crisp mixed green salad provide balance and freshness alongside this rich creamy chicken.

Reheating

FAQs
Can I use frozen chicken breasts in this recipe?
Yes, you can use frozen chicken breasts, but it may require extra cooking time. It’s best to check the chicken’s doneness before blending the sauce to ensure it’s cooked thoroughly.
Is there a substitute for heavy cream?

Can I add vegetables to this slow cooker meal?
Absolutely! Chopped bell peppers, mushrooms, or spinach can be added to the slow cooker at the beginning for extra nutrients and flavor. Just consider their cooking times and textures.
How spicy is this dish with the crushed red pepper flakes?
The crushed red pepper flakes only add a gentle warmth and a subtle kick. You can omit them if sensitive to spice or increase slightly if you love more heat.
Can I omit the Parmesan cheese?
While Parmesan adds a wonderful depth of flavor, you can omit it for a milder taste or if you have dietary restrictions, but keep in mind the sauce may be less savory.
