Blackened salmon is so easy to make and the crispy skin is truly life-changing! In just 10 minutes, you too can be feasting on this flavorful and healthy dinner!
Salmon is one of my staple foods – we make it one or two times a week usually, and I never get tired of it!
My go-to recipe for a long time has been this foil packet salmon with lemon and soy sauce. It’s so easy I can practically do it in my sleep and has almost no hands-on time, so it’s perfect for a quick dinner after a long day at work! Just throw a couple ingredients in a foil packet, bake, and peel off the salmon skin after it’s cooked.
But recently I made some blackened salmon fillets — with the skin on. A quick sear on the top in a cast iron skillet, and a few minutes sizzling on the skin side resulted in the most flavorful, moist and flaky salmon with shatteringly crispy skin.
It was a pretty mind-blowing difference for someone who usually removes the skin after cooking salmon in a foil packet! (still an advisable move for that kind of recipe where the skin is moist and never crisps up)
Leaving the skin on and getting it nice and crispy… It’s like eating bacon-wrapped salmon without using bacon. It’s like when you add potato chips to a sandwich for that nice bit of crunch. It’s just freaking amazing.
It is a little more hands-on than the foil packet recipe I love, but not by much.
I do recommend descaling your salmon fillets if they haven’t already had the scales removed (a couple minutes per fillet, and worth it so the scales don’t get stuck in your teeth), and if this is a flavor you like I’d also suggest making a jar full of homemade blackened seasoning so you don’t have to mix together all the spices every time.
Once the scales are off and the spices are blended, the salmon is ready to eat in less than 10 minutes. That’s what I call a quick dinner!
What is blackened seasoning?
If you’re not familiar with blackened seasoning, it’s a classic Cajun spice blend commonly used on fish and chicken. The spice blend and blackening technique was popularized in the 1980s by Chef Paul Prudhomme of K-Paul’s Louisiana Kitchen in New Orleans with his blackened redfish recipe.
Blackened seasoning is a little spicy (however spicy you want, since you’re mixing the seasoning yourself!) and gets nice and toasted when you sear your meat in a cast iron skillet. I’m basically addicted to the stuff now.
I’ve been using it in all kinds of recipes, not just blackened salmon! (okra and tomatoes, for example, or a cajun shrimp and sausage vegetable stir fry I just had this week – YUM!)
I’ve already gone through about a jar and a half of blackened seasoning since I posted the recipe a few weeks ago! Having a jar handy instead of having to mix up the spices every time I make blackened salmon shaves off that extra bit of prep time.
Plus, I don’t have to use measuring spoons — just sprinkle on top of the salmon fillets until they’re well-coated.
How to make blackened salmon
Chef Paul Prudhomme’s blackened redfish relied on a very simple technique that we will use for the salmon too.
It consists of first dredging the fish in melted butter (never a bad way to start a recipe), and then coating it with blackened seasoning.
I drizzle the butter over the fleshy side of the salmon fillets, then flip them over and swirl the tops around in any excess butter that’s on the plate to get them nice and evenly coated in butter.
Then, I spoon plenty of blackened seasoning over the fleshy side of the salmon and pat it down to adhere as much of the spice blend as possible to the fish. Yum!
Then, you cook the salmon in a preheated cast iron skillet with a little drizzle of olive oil.
A quick sear of 2-3 minutes on the fleshy side is just enough to form a nice toasty crust on the top, and finishing it off with an additional 5-6 minutes on the skin side cooks it through while giving that unparalleled crispy skin I can’t get out of my head.
Blackened salmon is very quickly rising in the ranks as the most frequently-made salmon recipe in my house.
If you haven’t tried eating crispy skin-on salmon or making it at home, you have GOT to give this recipe a shot. Let me know how you like it! Enjoy!

The Best 10-Minute Crispy-Skinned Blackened Salmon
- 4 4-oz. salmon fillets descaled, if necessary
- 2 tbsp butter
- 3 tbsp homemade blackened seasoning or use recipe below
- 2 tbsp olive oil
- 2 tsp paprika or smoked paprika
- 1 tsp chili powder
- 1 tsp kosher salt
- 1 tsp garlic powder
- 1 tsp dried oregano
- 1 tsp dried thyme
- 1/2 tsp onion powder
- 1/2 tsp black pepper
- 1/4 to 1/2 tsp cayenne pepper to taste
- Mix together blackened seasoning spices in a small bowl, or use a few tablespoons of homemade blackened seasoning.
- Descale salmon fillets if necessary. Pat salmon fillets dry on both side with paper towels. This helps the skin get crispy!
- Melt butter in the microwave for 30 seconds. Drizzle or brush butter over the fleshy side of the salmon fillets, and make sure the fleshy side is fully coated. I usually flip them over to mop up any melted butter that dripped off the sides onto the dish. You do not need to coat the skin side with butter (but it won't hurt anything either).
- Sprinkle blackened seasoning over the butter-coated fleshy side of the salmon fillets until fully coated, and pat down with dry fingers to make sure the spices adhere to the fish.
- Preheat a cast iron skillet over medium. Although tempting, don't preheat over high, or you will burn your spices! Medium will be plenty hot for this. Once hot, add about 1 tbsp olive oil.
- Place salmon fillets fleshy-side down in the cast iron skillet and cook for 2-3 minutes without moving, or until spices are nice and toasty brown-black. Flip them over so they're skin-side down and cook for an additional 5-6 minutes. After flipping them, I like to add another tbsp or so of olive oil and swirl it around a little so it gets under the skin to help them crisp up even more. Salmon should flake easily with a fork.
- Remove from pan and serve immediately, garnished with parsley, if desired. Enjoy that crispy skin!
