Heat a heavy- bottom stock pot over medium heat. Add the vegetables and allow it to heat up.
Gently place the seasoned chicken into the oil and sear on each side for 4 minutes (this is to brown the chicken). Remove the chicken and set aside.
Next, add the sliced sausage directly into the same pot and brown on each side for about 2 minutes. Remove the sausage and set it aside.
Start the roux: Turn the heat up to medium-high.Add the vegetable oil and allow it to heat up for at least one minute.
Begin to gently add in the flour a little at a time, while whisking continuously. Once all of the flour is added to the oil, continue to whisk for about 15 minutes.
The flour/oil mixture will begin to get more and more brown as it cooks, (it is not burnt)! The roux is ready when it is a deep chocolate brown color, and it is thick like a cookie batter.
Once the roux reaches the right color and consistency, add all of the veggies (okra, celery, onion, and green bell pepper) directly into it and sauté them for 5 minutes.
While the veggies are sautéing, cut the chicken into bite-size pieces.
Pour the chicken stock directly into the roux and stir it until everything is combined.
Gently add in the chicken and sausage and mix it all together. Add in all of the seasonings: bay leaves, Cajun seasoning, black pepper, and salt (to taste). Cover the pot and allow it to simmer for at least one hour.
Adjust desired thickness by adding water if needed (may need to adjust salt as well). Serve with file powder if desired.
Serve over cooked white rice.

Notes
Add file powder to each individual serving instead of the whole pot of gumbo.
