Instructions
1. How to Cook Blackened Salmon
2. In a small bowl, combine the paprika, cayenne pepper, onion powder, salt, white pepper, black pepper, basil, thyme, and oregano. Mix until evenly combined.
3. Pat the salmon fillets completely dry with a paper towel. This is crucial for getting a good crust.
4. Pour about half of the melted butter into a shallow dish. Dip each fillet in the butter, coating all sides.
5. Generously coat the fillets with the spice mixture, pressing gently to help it adhere. Drizzle the remaining butter over the seasoned fillets.
6. Preheat a heavy-bottomed skillet (cast iron is best!) over high heat until it is smoking slightly.
7. Carefully place the fillets in the hot skillet. Cook for 3 to 4 minutes, undisturbed, until the spices form a dark, blackened crust.
8. Flip the fillets and cook for another 2 to 3 minutes, or until the fish is opaque and flakes easily with a fork.
9. Remove from the skillet immediately to prevent overcooking. Serve warm and enjoy!

Pro Tips
• for the Best Crust
• Use a Cast-Iron Skillet: For that signature char, nothing beats cast iron. It gets screaming hot and retains heat evenly, which is key to toasting the spices without burning the fish.
• Bring Fish to Room Temp: Let your salmon sit on the counter for 15-20 minutes before cooking. A cold fillet hitting a hot pan can cook unevenly.
• Don’t Crowd the Pan: Give each fillet at least an inch of space. Overcrowding traps steam, which will ruin your chances of getting that beautiful, crispy blackened crust.
• Don’t Overcook: Salmon cooks fast! Pull it from the heat when the center is still slightly translucent (around 125°F / 52°C). It will continue to cook as it rests, resulting in a perfectly juicy fillet.
FAQ
Q: What makes salmon ‘blackened’
A: Blackened salmon gets its signature dark crust from a generous coating of spices, like paprika and cayenne, that are seared at a very high heat in a skillet. It’s the spices toasting, not the fish burning, that creates the delicious, dark, and flavorful crust.
Q: Can I make this recipe less spicy
A: Yes, you can easily adjust the spice level. The heat comes from the cayenne pepper. Simply reduce the amount of cayenne or omit it completely for a milder, but still incredibly flavorful, version of the dish.
Q: Is a cast-iron skillet necessary for blackened salmon
A: A cast-iron skillet is highly recommended for the best results because it gets extremely hot and holds heat evenly, which is perfect for creating the signature crust. However, any heavy-bottomed skillet that can handle high heat will also work.
Q: How do I prevent my salmon from overcooking
A: The key is to watch it closely as it cooks quickly. Cook for 3-4 minutes on the first side, then flip and cook for just 2-3 minutes more. Remove the salmon from the pan when it flakes easily and the center is still slightly translucent. It will finish cooking from the residual heat as it rests.
Pro Tips
- Use a cast-iron skillet heated over high heat until it smokes slightly. Its even, ferocious heat is what toasts the spice crust without burning the fish underneath.
- Pat the fillets completely dry with paper towels before dipping them in butter and spices. A dry surface is crucial for forming the crust.
- Let the salmon sit out for 15-20 minutes before cooking. A cold fillet hitting a hot pan cooks unevenly and can dry at the edges.
- Give each fillet at least an inch of space in the pan. Crowding traps steam, and steam is the fastest way to lose the blackened crust.
- Pull the fillets from the skillet when the center is still slightly translucent, around 125°F / 52°C. Carryover heat finishes them to a juicy medium as they rest.
Frequently Asked Questions
How do I know when the blackened salmon is done?
Pull it from the heat when the center is still slightly translucent, around 125°F / 52°C, and it flakes easily with a fork. It keeps cooking as it rests.
Can I cook blackened salmon in a non-stick pan?
You can, but cast iron is what produces the signature dark char because it holds high heat so evenly. With non-stick, get the pan properly hot before the fillets go in.
How spicy is the blackening seasoning?
It carries real heat from a tablespoon of cayenne pepper alongside the paprika. Halve the cayenne if you want a milder crust without losing the blackened flavor.
Is blackened salmon keto-friendly?
Very much so. One serving has just 3g total carbs with 2g of fiber and a full 66g of protein.
