Prepare Ingredients: Chop all vegetables and debone the rotisserie chicken. Slice the sausage. Refrigerate until ready.
Make the Roux: Combine flour and oil in a large saucepan over medium-high heat. Stir constantly for about 1 hour until it reaches a milk-chocolate color. For a darker roux, cook slightly longer.
Cook Vegetables: Add bell pepper, onion, and celery to the roux. Cook for 10 minutes until softened.
Brown Sausage: In a separate pan, cook the sausage until lightly browned. Add chicken stock to loosen any drippings. Combine sausage with the roux and vegetables.
Add Stock and Spices: Pour in the remaining chicken stock. Add Cajun seasoning, garlic powder, salt, and bay leaves. Let simmer for 15–20 minutes.
Add Water: Stir in 2 cups of water. Bring gumbo to a gentle boil and skim excess oil from the surface.
Add Chicken: Stir in the deboned rotisserie chicken. Cover and simmer for 1.5 hours, stirring occasionally.
Serve: Remove bay leaves and serve hot over cooked white rice.
Notes
Use Richard’s Cajun Style Roux for a shortcut.Skim the oil for a lighter gumbo, or leave it for richer flavor.The recipe is forgiving – adjust Cajun seasoning according to taste.
