Smoked Sausage Gumbo Casserole

Preheat oven to 350°. Spray a 4-quart baking dish with cooking spray. Set aside.

In a large Dutch oven, heat 14 cup vegetable oil over medium-high heat. Add onion, celery, and bell peppers. Cook, stirring frequently, for 10 minutes. Add rice; cook for 2 minutes, stirring constantly. Add broth and tomatoes; bring to a boil. Reduce heat to medium-low, and cook, covered, until rice is tender, approximately 20 minutes. Remove from heat.

In a medium skillet, combine remaining ½ cup vegetable oil and flour; cook over medium heat, stirring constantly, until roux is a caramel color, about 10 minutes. Transfer roux to Dutch oven.

Add sausage, okra, hot sauce, Worcestershire sauce, Creole seasoning, and garlic powder to Dutch oven, stirring to combine. Spoon mixture into prepared pan.

Cover with heavy-duty foil, and bake until heated through, 30 to 45 minutes. Uncover, and garnish with green onions and oregano, if desired.
