Naturally heart-healthy and gluten-free, this enticing seafood recipe is an excellent way to enjoy lean protein without sacrificing the bold, "blackened" crust you crave from a traditional cast-iron skillet preparation.
This recipe prioritizes heart health by using lean red snapper and a nutrient-dense sauce made from fresh peppers, celery, and tomatoes. By controlling the sodium in the Creole seasoning and using healthy fats in moderation, you get all the traditional Louisiana flavor while maintaining a low-cholesterol profile.
No, red snapper is a lean fish that is naturally low in cholesterol and saturated fat, making it an excellent choice for a heart-healthy diet.
While lemon butter is popular, a tomato-based Creole sauce is often considered the "best" for blackened fish because the acidity of the tomatoes balances the smoky heat of the spices.
Yes! Red snapper is one of the best fish for blackening because its firm texture prevents it from falling apart in the pan while the skin gets beautifully crisp.
A healthy Creole sauce consists of sautéed garlic, onions, bell peppers, and celery (the "holy trinity") simmered with tomatoes, low-sodium broth, and a blend of Mediterranean herbs like oregano and thyme.
Explore our collection of heart-healthy seafood and Southern fish recipes that deliver authentic Creole flavor while staying low in saturated fat and sodium.

Recipe yields 4 servings
Heat a large skillet over medium heat. Brush red snapper with 1 tablespoon melted butter; sprinkle with blackened seasoning. Place, skin side down, in hot skillet; drizzle 1/2 tablespoon melted butter over fillets. Cook for about 4 minutes, or until blackened; turn fillets carefully and drizzle remaining 1/2 tablespoon butter over fillets. Cook for 2 to 3 minutes. Serve with Creole sauce.
In a medium saucepan, heat 1 tablespoon butter and oil over medium low heat. Add garlic, onions, peppers and celery. Sauté vegetables for about 2 minutes, or until just tender.
Meanwhile, in a small cup, combine the paprika, Creole seasoning, thyme, oregano, basil, Worcestershire sauce, hot-pepper sauce and black pepper. Stir tomatoes and seasoning mixture into the vegetables. Sauté for 1 minute longer.
Add chicken broth and bring to a boil. Stir in the scallions. Simmer, uncovered, for 10 minutes or until the mixture thickens. Stir in the tomato paste until fully blended. Remove from heat and stir in the remaining 2 tablespoons butter.
In a bowl, mix the blackened seasoning ingredients well and funnel into a shaker.
To round out this meal, pair your snapper with high-fiber sides that soak up the delicious Creole sauce. Brown rice or quinoa are perfect bases, while roasted okra or a crisp green salad add a refreshing crunch. For a more traditional feel, serve it alongside a piece of low-sodium cornbread.
If you can't find red snapper, tilapia, cod, or grouper are excellent firm white fish substitutes that stand up well to the blackening process.
Use a high-quality vegetable broth if you prefer to avoid chicken broth; just ensure it is low-sodium.
For an even more heart-healthy profile, you can swap the butter for a light avocado oil, which has a high smoke point perfect for blackening.
