01 - Pat chicken thighs dry with paper towels and season lightly with salt and black pepper. Slice smoked turkey sausage into 1/4-inch rounds.
02 - In a large heavy-bottomed pot or Dutch oven, heat 1/4 cup vegetable oil over medium heat. Whisk in 1/2 cup all-purpose flour gradually, stirring constantly to prevent lumps. Cook the roux for 10-15 minutes, stirring continuously, until it reaches a deep peanut butter color. Be careful not to burn it.
03 - Add diced onion, green bell pepper, and celery to the roux. Cook for 4-5 minutes, stirring occasionally, until vegetables are softened and translucent.
04 - Stir in minced garlic, diced tomatoes, smoked paprika, dried thyme, dried oregano, cayenne pepper, bay leaves, salt, and black pepper. Cook for 2 minutes until fragrant, stirring constantly to prevent sticking.
05 - Add seasoned chicken pieces and sliced turkey sausage to the pot. Stir thoroughly to coat with the vegetable and spice mixture, ensuring everything is well incorporated.
06 - Gradually pour in 6 cups low-sodium chicken broth while scraping up any browned bits from the bottom of the pot. Bring to a boil, then reduce heat to low and simmer uncovered for 45 minutes, stirring occasionally, until chicken is very tender and flavors have melded together.
07 - Remove bay leaves from the pot. Taste the gumbo and adjust salt and pepper seasoning as needed. If desired, add hot sauce to adjust heat level.
08 - Ladle hot gumbo over cooked white rice. Garnish generously with sliced green onions and chopped fresh parsley. Offer additional hot sauce at the table.
