This slow cooker 5-ingredient creamy tomato basil chicken leans on a carton of store‑bought creamy tomato basil soup for both flavor and ease. You literally pour the soup and four simple pantry ingredients over raw chicken breasts in a slow cooker, then let gentle heat do the work. The result is a cozy, Italian‑leaning dish with a velvety tomato sauce and tender chicken—very much in the spirit of American slow-cooker comfort food, but with a nod to classic tomato-basil flavors from Italy. It’s the kind of weeknight dinner you can set up in minutes before work and come home to something that tastes like you fussed.
Serve the creamy tomato basil chicken over a bed of buttered pasta, creamy polenta, or simple steamed rice to catch all the sauce. A crisp green salad with a sharp vinaigrette or roasted vegetables (broccoli, green beans, or zucchini) balances the richness nicely. Warm crusty bread or garlic bread is perfect for mopping up the extra sauce, and a light Italian-style red wine or sparkling water with lemon makes an easy pairing if you’d like to round it out.
Slow Cooker Creamy Tomato Basil ChickenServings: 4
Ingredients
2 pounds boneless, skinless chicken breasts (about 4 medium)
1 (32-ounce) carton store-bought creamy tomato basil soup
1 cup heavy cream
1 cup shredded mozzarella cheese
1 teaspoon dried Italian seasoning
1/2 teaspoon kosher salt (or to taste)
1/4 teaspoon freshly ground black pepper (or to taste)
2 tablespoons chopped fresh basil or flat-leaf parsley, for serving (optional)
Directions
Place the raw chicken breasts in an even layer on the bottom of a 5- to 7-quart slow cooker. If the thicker ends are very large, you can tuck them toward the outer edges where the heat is a bit stronger.
Season the chicken lightly with the kosher salt, black pepper, and dried Italian seasoning, sprinkling the seasonings evenly over the top.
In a large measuring cup or bowl, whisk together the creamy tomato basil soup and heavy cream until smooth and well combined. This quick step helps the cream integrate nicely so it doesn’t separate as it cooks.
Pour the creamy tomato basil soup mixture evenly over the seasoned chicken breasts in the slow cooker, making sure the chicken is mostly submerged in the sauce. Use a spatula to nudge the chicken so the sauce can run underneath if needed.
Cover the slow cooker with the lid and cook on LOW for 4 to 5 hours, or on HIGH for 2 1/2 to 3 hours, until the chicken is very tender and registers at least 165°F in the thickest part.
Once the chicken is cooked, sprinkle the shredded mozzarella cheese evenly over the top. Cover again and let it cook on LOW (or keep on WARM) for about 10 to 15 minutes, just until the cheese is melted and the sauce is slightly thicker and creamier.
Taste the sauce and adjust seasoning with a pinch more salt or pepper if needed. If you prefer the chicken in pieces, you can slice or shred it directly in the slow cooker and stir it back into the sauce.
Spoon the creamy tomato basil chicken and sauce over your chosen base (pasta, rice, or polenta). Garnish with chopped fresh basil or parsley just before serving for a fresh, aromatic finish.
Variations & Tips
For a lighter version, swap the heavy cream for half-and-half; the sauce will be a bit thinner but still pleasantly creamy. If you prefer dark meat, boneless, skinless chicken thighs work beautifully and stay very tender—just add about 30 minutes to the LOW cook time. To add vegetables directly to the slow cooker, tuck 1 to 2 cups of sliced mushrooms, baby spinach, or zucchini around the chicken before you pour in the soup mixture; they’ll soften into the sauce as it cooks. For a little heat, add 1/4 to 1/2 teaspoon crushed red pepper flakes with the Italian seasoning. If you’d like more pronounced basil flavor, stir in 2 tablespoons of prepared basil pesto at the end of cooking instead of (or in addition to) the fresh basil garnish. Leftovers reheat well on the stovetop over low heat with a splash of extra soup, cream, or broth to loosen the sauce; they also make an excellent filling for baked pasta, stuffed peppers, or a hearty toast topper.
