How to Cook Salmon for Tacos and Fajitas
The trick to perfect seared salmon starts with a HOT skillet. Salmon cooks quickly, about 8 minutes total. Once you place it on the skillet’s surface, try not to touch it- otherwise, the fillets will stick and break apart.
Cast-iron skillets and stainless steel pans work best for searing; they do a great job of convecting heat which helps the fish cook evenly and develop a bronze sear.
How to Assemble Salmon Fajita Tacos
These salmon fajita tacos take less than 30 minutes to cook and assemble from start to finish. Here’s what to do:
- Prep
Preheat the oven to 350F and line a baking sheet with parchment paper. Season the salmon with fresh lime juice and taco seasonings. - Sauté the veggies
Grease a cast-iron skillet with oil and heat over medium-high heat. Add the veggies and sauté until tender. Transfer to a plate and set aside. - Sear the salmon
Add the salmon fillets to the hot skillet and cook for 3 to 4 minutes, on both sides, until tender. Transfer to a plate and roughly chop into large pieces. - Roast

Blackened Salmon Fish Tacos
Ingredients
- 2 limes, 1 juiced and 1 cut into wedges
- 2 teaspoons Cajun seasoning
- 1 lb salmon fillets, 4 pieces, skin removed
- 3 tablespoons vegetable oil, divided
- 1 red bell pepper, seeded and sliced
- 1 onion, sliced
- 1 cup grape tomatoes
- 1 tablespoon olive oil
- ¼ teaspoon salt
- 8 corn tortillas
- 1 avocado, pitted, peeled, and sliced
- Cilantro Lime Dressing
Instructions
- Preheat the oven to 350F and line a baking sheet with parchment paper.
- In a small bowl, combine the juice of 1 lime and Cajun seasoning. Spread the mixture on all sides of the salmon pieces.
- In a large cast-iron skillet, heat 1 tablespoon of the vegetable oil over medium-high heat. Add the sliced bell pepper and onion and cook, stirring constantly, for 5 to 7 minutes, until crisp-tender. Transfer the vegetables to a plate and tent with aluminum foil to keep warm.
- Heat the remaining 2 tablespoons of vegetable oil in the skillet. Add the salmon pieces and cook for 3 to 4 minutes until the bottoms blacken, then flip and cook the other side for 3 to 4 minutes until blackened. Transfer the salmon to a plate and give it a rough chop into smaller pieces.
- While the veggies and salmon cook, put the grape tomatoes on the prepared baking sheet; drizzle with olive oil, and sprinkle with the salt. Roast until the tomatoes start to burst and turn black on a few sides, 5 to 10 minutes.
- To assemble the tacos, start with a later of pepper and onion on each tortilla, top with some salmon, charred tomatoes, and avocado slices, and drizzle with the dressing. Serve with lime wedges.
