Blackened salmon is the ultimate salmon recipe: fast, easy and seasoned to perfection! It’s guaranteed to become a favorite.

Speechless. That’s what I was when Alex made this beautiful salmon recipe for me…and we hope you will be too. This Blackened Salmon is so flavor filled, you’ll feel like you ordered it at a restaurant. Even better: it’s fast and easy. The cooking process takes just 5 to 8 minutes. The homemade blackened seasoning has a savory intrigue and makes a crispy black crust on the outside of the fish. (Yeah, it blackens your pan too…but it’s 100% worth it.)

What is blackening, anyway?

First, let’s talk about the cooking method: blackening! Blackening is a style of cooking fish and meat in a cast iron skillet with a special blend of Cajun-style spices until the outside is crispy and blackened. It’s a technique that was popularized by celebrity Cajun chef Paul Prudhomme of Louisiana. He created a recipe for blackened redfish in this 1980’s cookbook that took the world by storm. Since then, blackening has become a popular technique. It’s all about the spices: and each chef has their own special blend. Let’s talk spices!

Ingredients in blackened seasoning

Here’s the thing about blackened seasoning: every chef has their own recipe, so there’s no “true” definition! The famous chef Paul Prudhomme had his own technique, and ours is heavily influenced by his method. Most recipes have spices familiar to Cajun cuisine: paprika, garlic, onion, oregano, thyme, and of course, cayenne for the heat. To our recipe we added a hint allspice and cloves to add intrigue and nuance.

This blackened seasoning blend has a hint of heat, but it’s mild. We wouldn’t even call it medium (our 3 year old loved it and didn’t detect heat). We recommend making this blend homemade because it’s just not the same otherwise! The ingredients in our homemade Blackened Seasoning are:

• Smoked paprika or sweet paprika
• Onion powder
• Garlic powder
• Oregano
• Celery seed
• Allspice
• Cloves
• Cayenne
• Salt and black pepper

How to buy a great piece of salmon

Aside from blackened seasoning, you’ll also need a fantastic piece of salmon for this blackened salmon. Lower quality salmon can taste very fishy and have a mushy texture. Here’s how to buy a great piece of salmon:

• Buy wild caught salmon. Wild caught is the way to go! It’s most sustainable and has the best flavor. Buy it either fresh from the fish counter or frozen works too.
• Coho is a good choice. We tend to like Coho salmon for its mild flavor: it’s a good middle of the road option in terms of price.
• Make sure to buy skin on. You’ll need skin-on salmon for this recipe.

Basic steps for how to make blackened salmon

You can skip right to the recipe if you’re ready to start this blackened salmon. But let’s chat briefly about the method, because knowing why you’re doing something in the kitchen is just as important as doing it.

• Brine the salmon. Brining takes 15 minutes, but it makes the best crispy on the outside, moist on the inside piece of salmon. Simply place the salmon in a salt water solution for 15 minutes; this also allows the salmon to come to room temperature.
• Add blackened seasoning. Pat the salmon dry and season with the homemade seasoning blend (you can mix it up while the salmon is brining).
• Sear the salmon skin side up for 2 to 3 minutes. Use a stainless steel or cast iron pan to get the best sear (not a non-stick pan)! Cook it over medium high heat until it’s cooked about halfway.
• Flip and cook 2 to 5 more minutes. The timing depends on the thickness of the piece of salmon, so use your best judgement. It should be just tender and pink at the center (about 130 degrees Fahrenheit).

Helpful tool: a fish spatula!

You don’t need any special tools for blackened salmon, but here’s one that makes the process a little easier: a fish spatula! A fish spatula is a wide slotted metal spatula that’s used to gently slide underneath fish when you’re searing it. It’s actually useful for many more tasks outside of seafood: like flipping eggplant pizzas or fries.

Use any large, wide spatula if you don’t have a fish spatula. Metal is nice so that it can easily slide under the fish skin. Want to grab one for yourself? Here’s a link to our fish spatula.

How to clean your pan after making blackened salmon

After making blackened salmon, your pan will have a lovely blackened char as well. (Sorry, it’s part of the fun!) Here are a few things to note about cleaning your pan:

• Don’t leave it for hours. You can eat your food first, of course! But don’t leave it for hours or overnight so that the black crust solidifies.
• “Deglaze” the pan. Deglazing the pan is a cooking technique where you add wine or another liquid to loosen the browned bits from the bottom of the pan. You can use it for cleaning too! Simply place water in the pan and heat it on a burner over medium heat. When the blackened bits start to loosen, scrape them off gently with a wooden spoon or silicon spatula.
• Use a non-toxic kitchen cleaner. If you have bits that are really stuck, we like to use a cleaner like Bon Ami.
