🍗 What Makes This Recipe So Good
- Bright, bold, delicious Cajun flavors shine in this recipe, highlighted by tender chicken, tangy tomatoes, and rich heavy cream. It’ll earn a permanent spot in your soup-season meal rotation for sure. It has one in mine!
- Every bit of this creamy Cajun chicken soup is robust, hearty, and satisfying. Packed with lean protein and naturally low carb, this is one soup that won’t have you raiding the pantry shortly after dinner.

👩🏼🍳 Chef’s Tips
- To get the juiciest, most flavorful chicken in your creamy Cajun chicken soup, use thinly sliced chicken breasts or even chicken tenders. I like to use 4 thin chicken breasts that weigh roughly ¼ pound each, or I’ll take 2 thicker chicken breasts and halve them into cutlets. That gives me more Cajun seasoning per chicken breast, and also helps them cook faster and more evenly.
- For a thicker, creamier soup, add 2 ounces of softened (room temperature) cream cheese when you add the heavy cream. For a thinner, more broth-like soup, use an additional ½ cup chicken stock.
- You can make your own holy trinity (onion, celery, and bell pepper blend) or you can probably find a frozen, pre-packaged blend at your local grocery store. It might be called mirepoix or even Cajun-style mirepoix.
