In a heavy pot, melt butter over medium heat. Whisk in almond flour and cook, stirring constantly, 12–15 minutes until deep mahogany brown.
Add onion, bell pepper, and celery (the 'trinity') to the roux, stirring to coat. Cook 5 minutes until softened.
Add garlic and cook 1 minute more.
Slowly whisk in chicken broth, then add bay leaves, thyme, and Cajun seasoning.
Add chicken and sausage. Bring to a simmer and cook, partially covered, 45 minutes.
Stir in okra and simmer 15 more minutes, until everything is tender and the gumbo has thickened.
Remove bay leaves, season with salt and pepper, and garnish with parsley and green onion before serving.
