Blackened Salmon

LOW EFFORT, HIGH REWARD. When it comes to easy, quick-cooking weeknight meals that taste restaurant delicious, salmon is often my answer.   Salmon is juicy, rich, buttery tender and literally takes minutes to cook!

I love re-inventing the friendly fish and couldn’t be more excited about this stellar Blackened Salmon recipe.  It might look fancy, but trust me, it is SO easy!  In less than 30 minutes, you’ll be sinking your teeth into tender, juicy, superbly crusted, spicy, smoky salmon fillets bathed in dreamy sauce.

RIDICULOUSLY DELICIOUS. The salmon is loaded with blackened seasonings then pan seared to create a charred, boldly seasoned exterior giving way to a buttery, juicy interior.  It’s then simmered in a sauce with onions, garlic, bell peppers, tomatoes and cream to drink up all the intoxicating flavors.

How to make Blackened Salmon

Let’s take a closer look at how to make Blackewith step-by-step photos (full recipe in the printable recipe card at the bottom of the post):

  1. Remove Salmon from the fridge:  Never cook salmon cold straight from the refrigerator otherwise it will cook unevenly. Instead, remove the fish from the refrigerator about 15 to 20 minutes before you’re ready to start cooking.
  2. Dry fillets:  Pat salmon dry with paper towels before brushing with oil or butter. Wet or moist salmon are more likely to stick to the pan and develop a lackluster crust.
  3. Grease salmon: Brush the salmon with melted butter or olive oil on ALL sides.  If you are using butter, the easiest way is to melt butter in a shallow dish then dip your salmon in the butter to coat all sides.
  4. Season salmon: Rub the salmon with the blackened seasoning just before you’re ready to cook. You don’t want to season it early or the  salt will draw moisture out of the fish and it will become dry.

5. Wait for a hot pan:  A hot pan doesn’t mean high heat, otherwise your salmon will burn on the outside and remain raw on the inside.  Instead, a hot pan means waiting until your pan is hot before anything touches the pan.  A hot pan keeps the salmon crispy on the outside and seals in the moisture.  The crust developed by a hot pan is not only flavorful but helps your salmon from sticking.  Without a golden crust, salmon is impossible to flip over without tearing.

6. Heat oil:  Once the pan is hot, add the oil and wait until it shimmers before adding the salmon. You want the oil to be hot but you don’t want it so hot that it is smoking. 

7. Cook salmon:  Add salmon to the pan and cook approximately 4 minutes per side, or until crispy and blackened.

8. Don’t fiddle:  Let your salmon cook undisturbed so it can sear properly and develop the charred, caramelized crust.  After the maillard reaction takes place, the caramelization will make the salmon automatically detach from the pan. Don’t disturb the salmon before this reaction or it will fall apart.

How to Make Blackened Salmon FAQs

Is blackened salmon good for you?

Blackened Salmon is not only delicious, but good for you too!  Salmon is a nutritional powerhouse. It is an excellent source of omega 3 fatty acids, protein, several B vitamins, antioxidants and potassium.
Studies show that salmon can help lower inflammation, which may reduce the risk factors for several diseases. A growing number of studies also suggest that including salmon in your diet might improve brain function and even reduce symptoms of anxiety, depression and the risk of age-related memory problems. In addition, this Blackened Salmon will make your taste buds happy.

What’s the difference between grilled and blackened?

While both methods can develop a flavorful char on the exterior of the food, blackening always involves coating the protein in blackened seasoning first.  Grilled foods can be blackened, but not all grilled foods are blackened.
Blackened foods, on the other hand, are intentionally cooked at high heat to develop the charred crispy crust.

Where did blackened salmon come from?

The blackening technique was populated by Chef Paul Prudhomme.  Chef didn’t have a grill at his New Orleans restaurant, so he used a hot cast iron skillet to develop the charred crust on his proteins.

What is blackened salmon seasoning?

You don’t need to be a chef or own a restaurant to make Blackened Salmon! It all starts with the seasoning.

Blackened seasoning is associated with Cajun or Creole cooking. It is a robust blend of herbs and spices resulting in a smoky, spicy, earthy, flavor. 

The red appearance on the blackened salmon is from the smoked paprika and cayenne pepper. Please do NOT substitute smoked paprika with regular paprika – the smokiness is everything. 

You can find smoked paprika with the rest of the spices at your grocery store.  I use it in ALL my Mexican recipes, so I promise your purchase will not go to waste. The rest of the blackened seasoning is a mix of common pantry seasonings you probably have on hand already.  You can also customize the heat by using more or less cayenne pepper.

Do you use oil or butter to blacken fish?

Oil is best for blackening fish due to its higher smoke point. Blackening involves cooking fish at very high temperatures, and oil can withstand these temperatures without burning or smoking excessively. Butter, on the other hand, has a lower smoke point and may burn at the intense heat required for blackening, leading to undesirable flavors and potentially a burnt appearance on the fish. Using oil allows for effective blackening without compromising the taste or appearance of the dish.

How do you get blackening seasoning to stick?

The best way to get blackening seasoning to stick is to brush your protein (fish, chicken, pork, etc.) with oil or butter before applying the spices. The fats provide a sticky surface for the spices to adhere to, contributes to the release of aromatic compounds in the spices, and helps retain moisture in the protein during cooking, preventing it from drying out.

Can you blacken fish without a cast iron skillet?

You don’t necessarily need a cast iron skillet to properly blacken fish. While cast iron is a popular choice due to its ability to retain and distribute heat evenly, other heavy-bottomed pans with high heat retention, such as stainless steel or carbon steel, can also be used effectively for blackening fish (seen in this recipe). The key is using a pan that can withstand the high temperatures required for the blackening technique.

Do you put olive oil on fish before seasoning?

Yes! Adding oil to a fish before seasoning helps the spices adhere, contributes to the release of aromatic compounds in the spices, and helps retain moisture in the fish during cooking, preventing it from drying out.

Blackened Seasoning

  • 2 tsp EACH smoked paprika, garlic powder, onion powder
  • 1 teaspoon salt
  • 1 tsp EACH dried oregano, dried thyme
  • 1/2 teaspoon pepper
  • 1/4-1/2 teaspoon cayenne pepper

Cream Sauce

  • 4 garlic cloves minced
  • 2 bell peppers (any color combo) chopped into 1” pieces
  • 1/2 medium red onion chopped
  • 1 1/2 cups low sodium chicken broth
  • 1 tablespoon cornstarch

  • Mix together all of the Spice Rub ingredients in a medium bowl. Remove 2 tablespoons and rub evenly all over salmon. Reserve remaining spice rub for the sauce.
  • In a large heavy bottom skillet, heat 1 tablespoon olive oil over medium-high heat (medium if your stove runs hot). Once hot, add fillets, turn heat down to medium and cook approximately 4 minutes, until crispy and blackened. Flip salmon over and cook an additional 3-6 minutes to your liking (will depend on thickness). If salmon is is browning too quickly, then turn down the heat. Remove salmon to a plate and tent with foil.
  • To the oil left in the skillet (don’t wipe out), add enough oil to equal 1 tablespoon if needed. Heat over medium-high heat. Once hot, add onions, and cook 3 minutes; then add bell peppers, garlic and reserved spice mix and cook 2 minutes.
  • Add half of the chicken broth to the pan (eyeball it) and whisk the remaining chicken broth with cornstarch until smooth. Add to pan along with heavy cream and diced tomatoes. Bring the sauce to a simmer and simmer until thickened, stirring occasionally.
  • Reduce heat to low and stir in Parmesan cheese until melted followed by lime juice. Add salmon back to the skillet and cook a minute or so to heat through. Taste and season with additional salt, pepper and/or cayenne pepper to taste. Garnish with freshly parsley and lime juice if desired.

    How are you doing.
    Hope everything is well?
    Can I substitute the roasted diced tomatoes for something else?
    This is very hard to find in the Netherlands.
    Chantalle x.

    • Jen says

      Hi Chantelle, I’m doing great, thank you! Yes, you can substitute them with regular diced tomatoes. I hope all is well with you! xo

  5. Chis says

    Do you think you could substitute another fish like tilapia?

  6. Heather says

    As another option, I made penne (8oz) and cooked just shy of al dente then added to the cream sauce to finish cooking. I put the salmon on top and covered to warm through and it was amazing!!! Your recipes are my go to when I want to cook a sure-fire favorite!

    • Jen says

      I LOVE your addition of penne – fabulous idea Heather! I’m so pleased this Blackened Salmon recipe was a winner and thank you for your kind words and making my recipes!

    FIVE STARS*****
    This is now one of my family’s favorite salmon recipes. There’s an excellent semi-upscale Louisiana seafood chain in Texas and a few other states beyond, called Pappadeaux Seafood Kitchen that would be proud to serve this. My husband kept saying, “Amazing. You’ve got to make this again.” Thanks for creating and sharing this great recipe.

    • Jen says

      Wahoo, thanks Jeanne! I’m honored this salmon is a “5 star recipe” in your book and a new favorite!

  9. Nicole A says

    Blackened Salmon was FANTASTIC!! Thank you for this recipe!

    • Jen says

      Thanks for taking the time to comment Nicole! I’m thrilled it was a hit!

  10. Summer says

    This recipe is so good! I served it with broccoli and quinoa and we gobbled it all up! Having the quinoa to pick up all of that tasty sauce was perfect. I’m thinking it would also be delicious over pasta or rice. Thank you for the amazing recipe!

    • Jen says

      Thank you so much Summer! I’m so pleased it was “gobble worthy!”

  11. Anjela says

    Hi! My fiancé rarely eats fish, but he loves this. Thank you so much for this wonderful recipe – it was a hit! Looking forward to making it again.

    • Jen says

      That is the ultimate compliment! Thank you so much Angela!

  12. Mai Allison says

    What if I can’t find skinless salmon?

    • Jen says

      You can cook the salmon with the skin on and remove the skin after cooking. Enjoy!

  13. Melanie says

    My family said this is so good they would eat the sauce on a flip-flop. Used fat-free half and half in the sauce instead of heavy cream with no loss of depth or flavor. And agree with adding pasta or rice we used whole wheat. Also if you have to substitute plain diced tomato be sure to add back some type of seasoning like paprika or cajun seasoning. Best thing I’ve made in a long time.

    • Jen says

      I’m so pleased your entire family loved this blackened salmon recipe so much Melanie, thank you! Thanks for sharing your tips as well!

  14. Debra says

    We had 3 for dinner and flaked the other the next day in a salad. Really good.

      Awesome Lisa! I’m thrilled this Blackened Salmon is a new favorite, thank you!

  16. Liz says

    This was wonderful. I’m a recipe following gal, did exactly what it said. Perfect. I did add pasta though, didn’t want to waste that great sauce.

    • Jen says

      Thanks so much Liz, I’m so happy you loved it!

  17. Hawke says

    My family loved this recipe! I couldn’t find any smoked paprika, but I was able to add some Liquid Smoke to the oil and coated the salmon in it. It turned out great!

    • Jen says

      I’m so happy it was such a hit, and what a great idea to add a hint of liquid smoke!

  18. Joy says

    I made this and there were 5 very happy people smiling throughout the dinner. Made a substitute for the cream because of my lactose intolerance, yet the sauce was very delicious. Had people using fingers to get every drop of sauce. Definitely a keeper! Thank you for sharing!

  28. Cindy says

    Not a review as I have not tried yet Looks fantastic and blackened is right up our alley. But hubby eats no cheese. Any recommendations to thicken sauce without the cheese? Can’t wait to try,

    • Jen says

      Thanks Cindy! I would increase the cornstarch to 1 tablespoon, enjoy!

  29. Erin Dumont says

    OMG this was amazing! A total crowd pleaser!!Will be making this regularly! More then 5 stars from my family!

    • Jen says

      Thank you so much Erin, I’m so pleased it was a hit!

  30. Amanda says

    My “go-to” for salmon now! Teenager approved! This is THE BEST blackened seasoning! I double the seasoning recipe and store it a mason jar so I always have some on hand. I usually smear it all over a full, half salmon filet and bake it in the oven at 425 for twenty minutes. Delicious! Thank you for another brilliant creation!

    • Jen says

      Awesome Amanda, I love that this will be on repeat as will the blackening seasoning! It sounds like I need to dedicate a post just to the seasoning!

  31. Gail says

    Fantastic! Will make this again and again. Also served sauce over angel hair pasta. Amazing dish!!

  32. Shanae says

    It was delicious, I added white wine (I added to much cornstach) and seasonings I added cajun with the blackened seasonings! OMG SO GOOD TY

    • Jen says

      Thank you Shanae, I’m so glad you loved it!

  33. MargieB says

    Excellent dish. My husband said that it was Restaurante quality. I had to change a few things. I didn’t have heavy cream so I substituted sour cream with a bit of milk. I also had some baby scallops so I added these at the end. My salmon wasn’t thick so I only cooked 2 minutes per side and it was perfect. Will make this again for sure.

    • Jen says

      Thank you so much Margie! I’m so pleased it was “restaurant quality” even with substitutions!

  34. Natalia says

    This recipe was fantastic! I added a cup of chopped asparagus with the bell pepper and garlic and increased the broth and cream by 1/2 cup. I served it over red lentil penne and made cornbread muffins on the side.
    I only made 1/2 the salmon and am going to make Cajun chicken to serve with the reserved sauce over spinach and ricotta ravioli later this week. Even so, I will absolutely be making it again! 10/10

    • Jen says

      Thank you so much for the 10/10 review Natalia! I love the idea of serving it over ravioli – yum!

  35. Selene says

    So easy to prepare following your instructions and OMG delicious!!! Thank you!

    • Jen says

      You’re so welcome Selene, I’m so pleased you loved it!

  36. Dllanclos says

    I’m going to try this, but I have one question…. Are you from Cajun Country?

    • Jen says

      I am not, just love the food!

  37. Keyla says

    I made this recipe and im adding it to one of my favorite ways of fixing salmon!!! I made it with pasta on the side and is perfect!! Thanks so much for sharing!

    • Jen says

      I love hearing that, thank you so much Keyla!

  38. Jen says

    I currently don’t have fire roasted tomatoes I’m hand, can I use just regular diced tomatoes instead?

  39. Sherry says

    Delicious! Will definitely be making it again! Can you make the sauce and salmon ahead and then put together for company? Also, only use 1/2 cup of drained fire roasted tomatoes? I have more than half a can of left over tomatoes. I served this on a bed of Faro and spinach.

    • Jen says

      Thanks Sherry! Yes, you can prepare the salmon and sauce ahead of time, and then I would slightly undercook the salmon. Reheat at 300 degrees in the oven just until warmed through.

  40. Kathleen says

    Amazing! Jen your recipes are legendary:)
    Love the confluence of flavors.

    • Jen says

      Thank you so much, Kathleen! I am so happy you enjoy my recipes!

  41. Sandy says

    YUM! Delicious and a nice kick to it. Definitely making again!
