- Heat one tablespoon of olive oil over medium heat in a large pot or deep skillet. Add bell pepper, celery and onion. Sauté for 5 minutes. Add garlic and sausage. Continue to cook for 3 minutes longer until sausage is lightly browned. Transfer to a bowl.
- Wipe pot clean. Add butter and remaining 2 tablespoons of oil over medium-low heat. Once butter is melted, add flour and stir well. Cook for 20-30 minutes or until roux turns a rich chocolate brown color, stirring frequently to prevent burning.
