After returning from New Orleans, I felt inspired to revisit and refresh some older recipes from my blog. This Cajun-inspired Blackened Red Snapper is one I originally developed in 2015, drawing major inspiration from the late New Orleans chef Paul Prudhomme and his classic cookbook “Chef Paul Prudhomme Louisiana Kitchen.” I aim to keep the bold, authentic flavors while simplifying and lightening the method for everyday home cooking.
Blackened fish is one of my favorite preparations for seafood: a generous coating of spices, seared in a very hot pan until a dark, flavorful crust forms. A squeeze of lemon brightens the dish and balances the robust Cajun-seasoned crust. This Blackened Red Snapper recipe is an easy weeknight winner that’s packed with flavor but refreshingly simple to prepare.
I like to serve this Cajun-Inspired Blackened Red Snapper with dirty Cajun-style cauliflower rice and either roasted okra or a crisp green salad. The spicy, smoky fish pairs well with light, bright sides that absorb the pan juices and contrast the charred crust.
Blackened Red Snapper
Ingredients
For the seasoning mixture
- 1 tsp kosher salt
- 1/2 tsp freshly cracked black pepper
- 1/4 tsp cayenne pepper (optional, for heat)
- 1 tsp paprika
- 1/2 tsp dried thyme
- 1/2 tsp dried oregano
- 1/4 tsp garlic powder
- 1/4 tsp onion powder
For the fish
- 2 red snapper fillets (8–10 ounces each)
- 2 tbsp avocado oil (or other high smoke-point oil)
- 1 lemon, cut into wedges (for serving)
- Fresh parsley, chopped (optional, for garnish)
Instructions
Make the seasoning mixture
- In a small bowl, stir together all seasoning ingredients until well combined. Taste and adjust salt or cayenne if you prefer more heat.
Cook the fish
- Pat the snapper fillets dry with paper towels. Generously coat the flesh side of each fillet with the seasoning mixture. There will likely be leftover seasoning if you only season two fillets—store the remainder for another use.
- Heat 2 tablespoons of oil in a large nonstick or cast-iron skillet over medium-high heat. The pan should be very hot but not smoking—when the oil shimmers, swirl to evenly coat the bottom of the pan.
- Place the fillets flesh side down and cook without disturbing until a dark brown to blackened crust forms and the fish is almost cooked through, about 5–7 minutes depending on thickness.
- Carefully flip the fillets onto the skin side. Press gently with the back of a spatula so the skin makes full contact with the pan (this prevents curling). Cook until fully opaque and it flakes easily with a fork, about 2–4 more minutes.
- Use a sturdy spatula to transfer the cooked fillets to plates. Serve immediately with lemon wedges and a sprinkle of fresh parsley if desired.

Tips, Serving Suggestions and Notes
This blackened red snapper works with many firm white fish such as grouper, mahi-mahi, sea bass, or cod. Swap fillet sizes and adjust cooking time accordingly. Use a high smoke-point oil like avocado, grapeseed, or refined coconut oil to achieve a proper sear without burning the oil.
To reduce splatter, make sure fillets are as dry as possible before seasoning. If you have a strong spice preference, increase or decrease the cayenne and paprika. Leftover seasoning stores well in an airtight jar for several weeks and is great on chicken, shrimp, or roasted vegetables.
For sides, try dirty Cajun cauliflower rice, simple cilantro-lime rice, roasted vegetables, or a bright salad to balance the bold spices. A wedge of lemon brightens the dish and cuts through the richness of the crust.
Storage
Store any cooked fish in an airtight container in the refrigerator for up to 2 days. Reheat gently in a low oven (250–275°F / 120–135°C) just until warm to preserve texture. Crispy char will soften with refrigeration.
