Dice the chicken breast and slice the andouille sausage into rounds.
In a large heavy-bottomed pot, heat the avocado oil over medium heat and whisk in the cassava flour constantly for 5-7 minutes until it turns a deep golden brown roux.
Add the diced onion, green bell pepper, and celery to the roux, sautéing until the vegetables are softened and aromatic.
Stir in the minced garlic, chicken, and sausage, cooking for 3 minutes to lightly brown the proteins.
Slowly pour in the chicken bone broth while stirring to incorporate the roux, then add the thyme, cayenne, smoked paprika, salt, and pepper.
Bring the mixture to a gentle boil, then reduce heat to low and stir in the sliced okra.
Cover and simmer for 20 minutes until the chicken is cooked through and the gumbo has thickened.
Garnish with fresh chopped parsley before serving in a deep bowl.
