Why I love this Recipe!

I love me a good taco. In fact, tacos are one of those foods I can never tire of. Probably because there are so many opportunities to introduce variety – you can vary up the protein, the veggies, the cheeses, the sauces, the heat, etc. Speaking of sauces, these tacos would pair perfectly with my avocado lime crema.

I’m a big fan of fish tacos too, especially in the summer. They’re light and refreshing and oh, so satisfying.

As a dietitian and mama, I’m all about quick salmon recipes I can make on a weeknight like my Sheet Pan Salmon and Veggies or my Baked BBQ Salmon.

And taco recipes are great for little ones (like my toddler) because you can serve it deconstructed and they can choose which toppings they’d like to put on. Usually for my 3 year old that means just cheese and avocado ;).

The blackened seasoning is easy to whip up or make in advance and the salmon only takes 6-8 minutes to cook in the cast iron! When’s the last time you cooked something in 6-8 minutes?!

I also really enjoy the flavor contrast of spicy blackened salmon with salty Cotija cheese and sweet corn as a topping. Cotija cheese is an aged Mexican cheese that’s firm and salty. I LOVE LOVE LOVE using it on my tacos. It’s kind of comparable to a feta cheese in terms of its texture and saltiness.

Ingredients You’ll Use

notes on ingredients:

salmon: the protein source and foundation of this taco! buttery, flaky, and packed with omega-3s!

Cotija cheese: an aged-Mexican cheese that’s white, firm and salty! Sub with feta if you can’t find it!

cilantro: a fresh herb that pairs well with Mexican-inspired cuisine and has a fresh citrus, lemony-peppery taste!

corn tortillas: I like using corn tortillas for tacos but you can also use flour or whole-wheat.

smoked paprika: spice that is smoky and spicy with hints of sweetness

thyme: gives spice rub an earthy lemony flavor

oregano: offers an earthy slightly bitter flavor to the blackened seasoning

cayenne: packs in some spicy heat to the rub

brown sugar: adds some sweetness to the seasoning

onion powder: adds a zesty, sharp pungent flavor to the spice rub

garlic powder: adds a milder garlic taste to the seasoning

Dietitian Geeks out Over Salmon!

It’s true. As a registered dietitian, I get a little nerdy about how much I love salmon, not only for its taste, but its nutritional content too.

Salmon is loaded with vitamin D, magnesium, selenium, and B vitamins, and omega-3s which are essential fatty acids because we don’t produce them in our body naturally (we need to get them from food sources and/or supplements).

Omega-3s (primarily DHA and EPA) are well-studied have been associated with a whole host of health benefits including reducing risk of cardiovascular disease, cancer, Alzheimer’s disease, dementia, and supporting infant health and brain development, and cognitive function. They are also being studied for their effects on depression, ADHD, inflammatory bowel disease and childhood allergies.

Let’s hear it for omegaaaaaas!

How to Make Blackened Salmon Tacos

  1. Make the seasoning. Whisk together smoked paprika, onion powder, garlic powder, thyme, oregano, cayenne pepper, salt and pepper until combined.
  2. Rub that salmon! Rub blackened seasoning all over flesh of salmon until its covered.
  3. Cook salmon. Heat olive oil in a cast iron pan over medium heat. Once the oil is hot, place salmon flesh side down into the pan, cooking until blackened, about 2-3 minutes. Flip salmon over, skin side down, and cook until internal temperature reaches 125-125 degrees F (for medium rare) or the filet flakes easily when a fork is inserted into the center, about 4-5 minutes.
  4. Assemble your tacos! Divide flaked salmon, Cotija cheese, and other desired toppings like my avocado lime crema among tortillas.

Expert Tips!

  1. I like to cook my salmon to medium-rare, which is an internal temperature of 125-135 degrees F, however the USDA recommends cooking seafood to well done or 145 degrees F to ensure it’s safe from possible food borne illness. This will result in a dryer, tougher piece of salmon. You choose which temp is right for you!
  2. Since this recipe is super quick to make, I like to take the extra 5 minutes to make my avocado lime crema to pair with these tacos. You could also whip it up ahead of time or while the salmon is cooking.

Storage and Preparation

Leftover blackened salmon can be stored in an airtight container in the refrigerator for up to three days. If you make different components like the avocado lime crema, I recommend storing those separately.

Blackened salmon leftovers can be reheated in the microwave for 30-60 seconds.

Description

These blackened salmon tacos are ready in just 20 minutes! Rubbed with blackened seasoning, seared in the cast iron, and topped with Cotjia cheese, these tacos are extra delicious when paired with my avocado lime crema.


Ingredients

Scale
  • 1.5 lbs salmon
  • 1 1/2 tablespoons smoked paprika
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon thyme
  • 1 teaspoon oregano
  • 1/2 teaspoon cayenne pepper
  • 1 teaspoon brown sugar
  • 1 teaspoon salt
  • 1/4 teaspoon pepper
  • 1 tablespoon olive oil
  • 8–10 corn tortillas
  • 1/2 cup grated or crumbled Cotija cheese
  • Optional toppings: sliced cabbage, cilantro, corn, avocado, or avocado lime crema

Instructions

  1. In a small bowl, whisk together smoked paprika, onion powder, garlic powder, thyme, oregano, cayenne pepper, salt and pepper until combined.
  2. Rub seasoning onto salmon filets or place seasoning onto shallow bowl or plate and press salmon, flesh side down, into the rub, coating the entire filet.
  3. In a cast iron pan, heat olive oil over medium heat. Once the oil is hot, place salmon flesh side down into the pan, cooking until blackened, about 2-3 minutes. Flip salmon over, skin side down, and cook until internal temperature reaches 125-125 degrees F* or the filet flakes easily when a fork is inserted into the center, about 4-5 minutes, depending on thickness. If salmon is thick (over 1.5 inches), you may need to cook a little longer.
  4. Divide flaked salmon, Cotija cheese, and other desired toppings like corn, avocado, cabbage or my avocado lime crema among tortillas.

Notes

  1. I like to cook my salmon to medium-rare, which is an internal temperature of 125-135 degrees F, however the USDA recommends cooking seafood to well done or 145 degrees F to ensure it’s safe from possible food borne illness. This will result in a dryer, tougher piece of salmon.

  1. best tacos recipe ever. sharing it with mom and asking her to make it for me hehe

  2. Your tacos look pure artistic and delicious; I’d gobble them up in minutes!

    I am definitely going to make these. Mouth already watering.
    Question though…how did you prepare the corn tortillas exactly, i.e., how did you blacken them around the edges, and how did you get the tortillas to keep their shape, like in your photos? Thanks in advance!

    • Hi Becky! I placed the tortillas over open fire on my gas stove range. Place tortilla on range, turn heat on to medium-high, let tortillas blacken around edges, about 15-30 seconds, and then using tongs, flip tortillas over and let cook until blackened around edges, another 15-30 seconds. And how I got them to keep their shape, some food styling magic :). I placed them right next to each other and then placed two lime halves on the outside.

    What a fun way to upgrade taco Tuesday! We tried these this week and they are a major hit! They reminded us of the Fish Shop tacos in PB!

  5. There are so many different things going on in this recipe that I love! The corn salsa, the salmon, the crispy shells – such a great, delicious combo!

  6. It looks like you doubled up the tacos: very important if using homemade ones too.

  7. Amy Lorraine Camenisch

    These look so delicious!!!

  8. Putting this on my menu for next week!

  9. Mmmm this looks like the perfect taco night idea :-).

  10. These sound incredible (I love all things salmon!), and your photography is fantastic!

    I made the salmon tacos with the corn avocado salsa for dinner last night for dinner. My husband and I both thought it was delicious! I can’t support using Norwegian salmon because we get our salmon from Sitka Salmon Shares and believe we need to support our local economy.
