Season and Prep the Chicken: Pat the chicken dry and season with salt, pepper, and a pinch of paprika. If using bone-in, leave the skin on for now; it adds flavor you’ll render out.
Brown the Sausage: In a large heavy pot or Dutch oven over medium heat, brown the andouille until nicely caramelized, about 5–7 minutes.
Remove to a plate, leaving the rendered fat in the pot.
Brown the Chicken: Add the chicken to the pot and brown on both sides, 3–4 minutes per side. Don’t fully cook it yet. Remove to the plate with the sausage.
Make the Roux: Add enough oil so you have about 1/2 cup fat total in the pot (use the sausage/chicken drippings plus extra oil if needed).
Sprinkle in the flour. Cook over medium to medium-low heat, stirring constantly with a flat-edged spatula, until the roux turns the color of dark chocolate, 25–40 minutes. Do not rush this step. If it starts to smell burnt, reduce the heat.
Sweat the Trinity: When the roux is dark, add the onion, bell pepper, and celery.
Stir well. Cook 5–7 minutes until softened. Add the garlic and cook 1 minute more.
Season the Base: Stir in paprika, thyme, oregano, cayenne, and bay leaves.
Toast the spices for 30 seconds to wake them up.
Add Stock Gradually: Slowly whisk in the chicken stock, a cup at a time, until smooth. Bring to a gentle simmer.
Return Meat to the Pot: Add the browned sausage and chicken (if using skin-on, you can remove the skin now). Reduce heat to low and simmer uncovered for 45–60 minutes, stirring occasionally to prevent sticking.
Shred the Chicken: Remove the chicken to a board.
Shred or chop into bite-size pieces; discard bones if used. Return meat to the pot. Simmer another 10–15 minutes to meld flavors.
Adjust thickness with a splash of stock if needed.
Final Seasoning: Taste and add salt, pepper, and optional Worcestershire or hot sauce. Stir in green onions and parsley. Off heat, you can add filé powder to slightly thicken and add earthiness. Do not boil after adding filé or it can turn stringy.
Serve: Spoon gumbo into bowls with a scoop of hot white rice.
Offer extra hot sauce at the table.
