Make the Roux
In a large, heavy-bottomed pot, heat oil or melt butter over medium heat.
Gradually whisk in flour, stirring constantly.
Cook 10–15 minutes until deep caramel-brown.
Sauté the Vegetables
Add onions, bell peppers, and celery; cook 5–7 minutes until soft.
Add garlic; cook 1–2 minutes until fragrant.
Add Meats
Stir in chicken and sausage, coating with roux and vegetables.
Cook 5 minutes to lightly brown chicken and release sausage flavor.
Add Broth and Seasonings
Pour in chicken broth gradually, stirring to combine.
Add Cajun seasoning, smoked paprika, thyme, bay leaf, salt, and pepper.
Bring to a boil, then reduce heat to low.
Simmer
Cover and simmer 45–60 minutes, stirring occasionally, until chicken is tender and flavors meld.
Add Okra and Finish
Add sliced okra in the last 10–15 minutes.
Stir in chopped parsley before serving.
Sprinkle file powder at the end if using.
Serve
Serve hot over cooked white rice.
Garnish with parsley or green onions, optional hot sauce.
