Gather all of your ingredients. Add vegetable oil to a large gumbo pot or dutch oven, and bring up to medium heat.
1 cup vegetable oil
In a second medium saucepan, cook the white rice.
2 cups white rice
Brown the chicken in batches (don't crowd the pan so the chicken browns properly). Remove to a platter and set aside.
8 chicken thighs
Reduce heat to medium-low, and add the flour to the hot oil and rendered chicken fat. Use your spatula to mix the flour and oil well, stirring constantly.
1 cup all-purpose flour
Continue stirring the flour in the hot oil. Keep things moving so the flour doesn't burn, which will ruin the roux.
For chicken gumbo, you want a dark chocolate colored roux. Continue cooking , constantly stirring the flour in the hot oil until you achieve a rich, dark color.
Add the onion, bell pepper, and celery. Sauté the vegetables until they are limp.
2 large onions, 1 cup green bell pepper, 1 cup celery
Add the chicken stock, garlic, thyme, bay leaves, cloves, allspice, cayenne and basil. Add salt and black pepper, to your liking.
3 clove garlic, 1 tsp fresh thyme, 3 bay leaves, 1/8 tsp powdered cloves, 1/8 tsp powdered allspice, 1/4 tsp cayenne pepper, 1/2 tsp fresh basil, 2 quart chicken stock, 1 tsp salt, 1/2 tsp black pepper
Reduce heat to low. Simmer 40 minutes, then add the chicken back to the pot and cook until tender, about 10 minutes more.
Remove from the heat, and add the chopped green onions.
1/2 cup green onions
Serve in a soup bowl over cooked long grain white rice. If desired, add a pinch of filé, which helps thicken the soup and adds flavor and aroma. Serve with freshly baked French bread.
1 tbsp gumbo filé
