To make the roux, stir together oil and flour in a medium saucepan until smooth.

Cook over medium-high heat for about 5 minutes, stirring constantly.

Reduce heat to medium; cook and stir constantly about 15 minutes more until it’s a dark, reddish-brown color. Cool.

Place water in a Crock Pot and add roux; stir.

Add sausage, chicken, okra, onion, pepper, celery, garlic, salt, black pepper, and red pepper.

Cover and cook on low heat for 6-7 hours, or on high heat for 3 hours.

Skim off the fat, and serve over rice.
