Absolutely. During a big calorie cut I made a lighter version I ate almost every week. File and thyme gave solid taste without the usual roux calories. Smoked chicken breast replaced the sausage smokiness. Garlic, Creole seasoning, thyme, a little Worcestershire, bay leaves and file went in along with tomato for body even though I skip it normally. Gumbo rules.
The taste of gumbo stands out thanks to browned flour combined with paprika.
