Authentic Cajun Chicken and Sausage Gumbo

In a heavy-bottomed Dutch oven or large pot, heat the vegetable oil over medium heat. Gradually whisk in the flour until smooth.

Cook the roux, stirring constantly, for 45-60 minutes, or until it reaches a dark chocolate color. Be patient; this is crucial for flavor. Do not let it burn. If small black flecks appear, discard and start over.

Add the diced onion, bell pepper, and celery (the 'holy trinity') to the dark roux. Stir well and cook for about 8-10 minutes, until softened.

Add the minced garlic and cook for another minute until fragrant.

Add the sliced andouille sausage and cook for 5 minutes, stirring occasionally, until lightly browned.

Add the chicken pieces and cook until lightly browned on all sides.

Gradually whisk in the chicken broth, ensuring no lumps form from the roux. Bring the mixture to a simmer.

Stir in the Worcestershire sauce, Cajun seasoning, and bay leaves. Season with salt and black pepper to taste. Remember that Cajun seasoning and sausage can be salty.

Reduce the heat to low, cover, and let the gumbo simmer gently for at least 1.5 hours, stirring occasionally, to allow the flavors to meld and the chicken to become very tender. The gumbo should thicken slightly.

Remove the bay leaves before serving.

Ladle the hot gumbo over cooked white rice. Garnish with fresh parsley and sliced green onions, if desired.
