In a small bowl combine all seasonings (salt, poultry seasoning, pepper, cayenne, and garlic powder) and beef base.
In a separate bowl, mix together celery, onions, and bell pepper (Holy Trinity).
In a Dutch oven over medium-high heat, heat oil until it shimmers.
Carefully add flour and stir constantly (if you are new to making roux start at a lower temp). Cook roux until dark brown (~20 minutes). Stir constantly or your roux will burn. It should look like melted chocolate when done.
Remove pot from heat and add seasonings, onions, celery, bell peppers. Stir until thick and well combined (~2 minutes).
Return pot to heat and add broth, okra, minced garlic, and bay leaves.
Combine and bring to boil, cover and let simmer for 10 minutes.
Add meat and let simmer for 15 minutes.
Serve over rice. Top with green onions and parsley. Enjoy.
