Pan Seared Salmon

Skinless portions of pan seared salmon hit with Cajun seasoning. Seared in a hot skillet, then basted in butter and thyme. Asparagus goes in first so it comes out charred. Whole dinner is done in thirty minutes. Cajun seasoning pairs perfectly with salmon.

Why Skinless Changes the Cook

Almost every pan seared salmon recipe you find is really a recipe for crispy skin. The skin renders, the fat protects the flesh of the filet and basically does all the work cooking.

Skinless portions don’t have that buffer. The difference between moist salmon and chalky salmon is about sixty seconds when you’re going skinless. So we take the pan down to medium high instead of screaming hot, and we add the butter after the flip.

The butter is doing the work here that skin would have done. Once it melts you’re spooning it back over top of the fish which gently finishes cooking the top from above while the bottom finishes below. Thyme gets added to the butter because hot butter wilts herbs and pulls flavor into the fish better than dry seasoning can.

If your portions come with skin then cook them skin down first, and give that side the majority of the cook time.

Right Up Your Alley

This is a very quick meal. You can probably have it ready within 30 minutes. If you love salmon this is right up your alley, and the Cajun seasoning just pairs perfectly with salmon.

You don’t wanna overcook it otherwise it’ll dry it out, so please pull it off around 125 internal temperature.

For the asparagus just a nice quick sear on those. I like a nice and crunchy, but you can always cook them to your liking.

Pull It Early

Cooking salmon isn’t difficult but drying it out is an easy way to screw it up.

I pull mine at 125 for medium rare and the salmon continues to cook a few degrees while it rests after coming off the pan. If 145 seems better to you because that’s what the USDA recommends then cook it that far. Just know that every degree you cook past 125 you lose moisture. Past 140 you’ll start to see the fat begin to sweat out on the surface of the fish as white curds.

Asparagus is the exact opposite concept. If you like it crunchy then it’s a quick hard sear and off the pan. Cook it a little longer if you want it softer.

Make-Ahead and Storage

This recipe is not make-ahead friendly. Thirty minutes start to finish and salmon doesn’t reheat kindly.

Leftovers can keep in the fridge and be fantastic cold the next day flaked over a salad, more than they are reheated. If you’re reheating, go medium low and take it out early.

Miguel’s Tips

  • Asparagus first, dry pan, high heat = Char.
  • Drop the heat before adding salmon. High heat is only for our veggie friends.
  • Leave salmon alone for the first side. Don’t slide it around and try to flip it early for a sear.
  • Butter goes on after you flip salmon, not before. Butter burns fast if you add it to a hot pan.
  • Pull your salmon early! There is absolutely no coming back from dried out salmon.

Frequently Asked Questions

What temperature should I cook salmon to?

Pulling mine at about 125 for medium rare. USDA recommends salmon be cooked to 145. You do you boo boo! Just keep in mind that it will continue to cook once you pull it off the pan.

Can I use skin-on salmon?

Absolutely. Just remember to cook the skin side down first and give it the majority of the cook time. Then flip it and baste as normal.

Do I need a cast iron pan?

No, but you need something that will hold heat. Cast iron or heavy stainless both work. You don’t want cookware that dips in temperature when you add food to it.

Cajun Pan Seared Salmon with Charred Asparagus

Skinless salmon portions seasoned with Cajun, seared in a hot skillet and basted with butter and fresh thyme. The asparagus goes in first on high heat so it comes out charred. The whole dinner is done in about thirty minutes.
Prep Time 10 minutes
Cook Time 15 minutes
Total Time 25 minutes
Servings: 3 servings
Course: Dinner, Main Course
Cuisine: American, Cajun

Ingredients
  

Salmon
  • 3 salmon portions, 6 oz each skinless
  • Cajun seasoning To taste, all over the salmon.
  • 2 tbsp cooking oil For the salmon only. The asparagus goes in a dry pan.
  • 2 tbsp butter Added after the flip.
  • Fresh thyme A few sprigs, into the butter.
Charred Asparagus
  • 1 lb asparagus Woody ends trimmed off and rinsed.
  • Cajun seasoning To taste, added while it chars.

Equipment

  • Heavy skillet Cast iron or heavy stainless. You want something that holds heat when the food goes in.
  • Tongs
  • Spoon For basting.
  • Instant-Read Thermometer

Method
 

Prep and Char the Asparagus
  1. Pat the salmon portions dry and season all sides generously with Cajun seasoning. Set aside.
  2. Trim the woody ends off the asparagus and rinse. Heat the skillet over high heat and add the asparagus to a dry pan. Cook until nicely charred, turning occasionally.
  3. Hit the asparagus with a little Cajun seasoning, then pull it out of the pan and set it aside. A quick hard sear leaves it crunchy. Cook it a little longer if you want it softer.
Sear and Baste the Salmon
  1. Turn the heat down to medium high and add about 2 tablespoons of cooking oil to the pan.
  2. Place the seasoned salmon in the pan and leave it untouched for about 3 minutes.
  3. Flip the salmon, then add the butter and a few sprigs of fresh thyme. As the butter melts, tilt the pan and spoon it back over the fish to baste.
  4. Cook for about 3 more minutes. Pull the salmon at around 125°F internal for medium rare. It will keep climbing a few degrees off the heat.
Serve
  1. Serve the salmon over the charred asparagus.

Notes

Doneness: Miguel pulls this at 125°F for medium rare, and it keeps cooking a few degrees off the heat. The USDA recommends 145°F for fish. Cook to the temperature you are comfortable with, knowing that every degree past 125°F costs moisture and past 140°F the fat starts to surface as white curd.
Skinless changes the cook: Without skin there is no fat buffer between the fish and the pan, so the heat comes down to medium high and the butter goes in after the flip to do the job the skin would have done.
Asparagus first, dry pan: The char comes from high heat and a dry surface. Oil goes in only when the salmon does.
Butter after the flip: Butter added to a screaming hot pan will burn before the fish is done.
Not a make ahead: Thirty minutes start to finish and salmon does not reheat well. Leftovers are better cold, flaked over a salad.
