Blackened Fish With Lemon Butter Sauce
Blackened fish with lemon butter sauce is an easy skillet seafood dinner made with thin white fish fillets, Cajun blackened seasoning, garlic, butter, and fresh lemon. The fish cooks quickly and comes out tender, flaky, and full of flavor.
Ingredients
Blackened Fish
- 2 thin boneless white fish fillets, about 6 ounces each, thawed if frozen
- 1 tablespoon blackened seasoning, homemade or store-bought
- 1 tablespoon olive oil
Lemon Butter Sauce
- 2 tablespoons unsalted butter
- 1 small garlic clove, minced or pressed
- 2 teaspoons fresh lemon juice
- 1 tablespoon chopped fresh parsley
- kosher salt and black pepper to taste
- lemon wedges for serving
Instructions
- Take the fish out of the refrigerator about 15 minutes before cooking. Pat dry with paper towels.
- Season both sides of the fish with blackened seasoning.
- Heat 1 tablespoon olive oil in a large nonstick, cast iron, or stainless steel skillet over medium-high heat.
- When the oil is hot but not smoking, add the fish. If the skin is still on, place the fish skin side down first.
- Cook thin fillets for 2 to 3 minutes per side, until the outside is dark and seasoned. The fish is done when it flakes easily with a fork and reaches 145°F in the thickest part.
- Transfer the fish to a plate and keep warm.
- Lower the heat to medium. Add the butter and garlic to the same skillet. Cook for about 30 seconds, scraping up the browned bits from the pan. Stir in the lemon juice and parsley. Taste and add salt and black pepper if needed.
- Spoon the sauce over the fish and serve with lemon wedges.
Notes
Thin white fish fillets usually cook in 2 to 3 minutes per side. Thicker fillets, such as mahi mahi or swordfish, may need 4 minutes per side.
Use our homemade blackened seasoning or a store-bought blend. Paul Prudhomme’s Blackened Redfish Magic works well.
Blackened seasoning usually contains salt, so do not add extra salt to the fish until after cooking.
Storage: Store leftover blackened fish in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over low heat with a little butter.
