Step-by-Step Instructions

Prepare the Chicken
Pat chicken dry and cut into 1-inch pieces. Toss with 1 tsp Cajun seasoning, ½ tsp salt, and ¼ tsp black pepper. Set aside.

Prep Vegetables and Spices
Finely dice onion, celery, and green bell pepper (holy trinity). Mince garlic. Combine 2 Tbsp Cajun seasoning, smoked paprika, thyme, and cayenne in a small bowl. Measure broth. Chop parsley and green onions for garnish.

Sear the Chicken
Heat olive oil in a large Dutch oven over medium-high heat. Sear chicken in batches until golden brown, 3–4 minutes per side. Remove and set aside.

Make the Roux
Reduce heat to medium. Melt butter, scraping up fond. Whisk in flour and cook 3–5 minutes until light golden or peanut-butter colored.

Sauté Aromatics
Add holy trinity to the roux. Sauté 7–10 minutes until softened and onion is translucent. Stir in garlic for 1 minute, then add spice blend and cook 1 minute more to bloom.

Build the Soup
Gradually whisk in 1 cup broth, scraping the bottom. Add remaining broth. Return seared chicken and bay leaf to the pot.

Simmer
Bring to a gentle simmer, then reduce to low, cover, and cook 20–25 minutes until chicken is tender and flavors meld.

Finish with Cream
Remove bay leaf. Taste and adjust seasoning. Remove from heat and slowly stir in heavy cream until fully incorporated.

Garnish and Serve
Ladle into bowls. Garnish generously with chopped parsley and green onions. Serve immediately.

Troubleshooting Common Issues

Why This Recipe Works

Searing the chicken builds flavorful fond while the roux provides silky body and nutty undertones. The holy trinity sautéed in that roux creates the aromatic foundation of Cajun cooking, and blooming the spices releases their full potential. Gentle simmering tenderizes the chicken and melds flavors, while adding cream off-heat ensures a stable, luxurious finish without separation. The result is a perfectly balanced, hearty soup with bold yet harmonious Cajun character.
