Air Fryer Salmon Fajitas (Easy 5-Ingredient Dinner Recipe)

Easy-to-Make Salmon Fajitas in the Air Fryer (Fast Weeknight Win)

Salmon is kind of like a delicacy in our home — we don’t always eat it. But when we do, I love cooking it in the air fryer because it’s quick, simple, and consistently delicious.

This air fryer salmon fajitas recipe is one of our favorites (even picky eaters and “I don’t like fish” people enjoy it). It’s packed with flavor, uses just a handful of ingredients, and feels restaurant-worthy without being fussy. You can have dinner on the table in about 15 minutes — and the cleanup is easy, too.

What Ingredients are Best for Salmon Fajitas?

If you want quick and simple salmon fajitas, you need an air fryer and just a few ingredients. Here’s what you’ll use:

• Salmon fillets (2–4 fillets)
• Avocado oil (or olive oil)
• Fajita seasoning kit (or homemade seasoning below)
• Frozen peppers and onions (12-ounce bag) — or fresh sliced vegetables
• Tortillas (flour or corn)

Quick note: If your salmon fillets are especially thick, you may need an extra minute or two. If they’re thinner, start checking early so they don’t dry out.

Fajita Seasoning Options (Store-Bought or Homemade)

I love using a premade fajita seasoning mix because it cuts down prep time and still delivers big flavor. But if you don’t have a kit on hand, this homemade seasoning works beautifully.

Optional Homemade Fajita Seasoning:

• 2 teaspoons chili powder
• 1 teaspoon paprika
• 1 teaspoon dried oregano
• 1 teaspoon salt
• 1 teaspoon sugar
• 1/2 teaspoon cumin
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/4 teaspoon cayenne pepper

Reader Tip: How much homemade fajita seasoning should I use?

This recipe makes enough seasoning to coat the salmon and vegetables well. If you like fajitas bold (I do!), go ahead and use it all. If you prefer milder flavor, start with about 2/3 of the mix and adjust from there.

Frozen Pepper and Onion Substitute

Like the premade seasoning, I love using a frozen package of peppers and onions because it’s so easy to toss into the air fryer.

If you’d rather use fresh veggies, use about 1/2 onion (white or yellow) and 1 bell pepper (red, yellow, or orange are especially sweet). Slice thin for even cooking.

Air Fryer Tips for Perfect Salmon Fajitas

Is an air fryer the best way to cook salmon? For quick + quality salmon, it’s hard to beat. You get a tender, flaky center with very little effort — and it’s ideal for busy weeknights.

Tip #1: Prevent sticking with a foil sling

To keep salmon from sticking (and make cleanup easier), create a simple foil sling:

• Tear a piece of foil about 1/3 the width of your air fryer basket.
• Fold it lengthwise so it fits neatly in the basket, leaving “handles” on the sides.
• Place the salmon on top of the foil and cook as directed.

If you don’t want to use foil, parchment paper can work — just lightly spray it with oil so the salmon releases easily.

Tip #2: Cook salmon and veggies together

Cooking the salmon with the peppers and onions speeds everything up. Place the salmon on the foil sling, then nestle the peppers and onions around it. Lightly spray with avocado oil (I love the Mistifi oil sprayer for this), then sprinkle seasoning over the salmon and veggies. Rub most of the seasoning onto the salmon for maximum flavor.

What temp should salmon be cooked at?

Tip #3: Cook at 350°F/175°C. Set the air fryer to 350°F and cook the salmon and vegetables together. You don’t need to preheat (yay!), though preheating is optional if you prefer.

How long should salmon be cooked in the air fryer?

Cook for 8–10 minutes at 350°F. Thicker fillets may need a touch longer; thinner fillets may finish sooner. Start checking around the 8-minute mark.

Tip #4: Use an instant-read thermometer

Salmon is done at 145°F/62.8°C and should flake easily. An instant-read thermometer makes it simple to get perfect results.

What Should I Put on Top of Fajitas?

Tip #5: Finish with fresh toppings! This is where salmon fajitas go from “good” to “WOW.” Try:

• Avocado slices or guacamole
• Fresh lime wedges
• Salsa or pico de gallo
• Shredded cabbage or a crunchy slaw mix
• Cilantro
• Cotija, feta, or shredded cheese

Make-Ahead & Party Planning Tips

These salmon fajitas are fast enough for weeknights, but they’re also a sneaky-good “host move” for get-togethers — they feel a little fancy without the stress.

• Prep ahead: Mix your seasoning and set out toppings earlier in the day. Slice fresh peppers/onions (if using) and store in the fridge.
• Set up a fajita bar: Put tortillas in a towel-lined basket, then set out toppings in small bowls so everyone builds their own.
• Leftover win: Store salmon and veggies in an airtight container for up to 2 days. Reheat at 325°F just until warmed through.

Air Fryer Salmon Fajitas FAQ

Do I use all of the homemade fajita seasoning on the salmon?

This recipe makes enough seasoning to coat the salmon and vegetables well. You can absolutely use less if you prefer milder flavor, but if you like bold, restaurant-style fajitas, using the full amount works great.

Reader question: “Using your recipe to make my own fajita mix, do I use the entire seasoning mix to season the salmon?”

Answer: The recipe makes enough to season well. You may want less or all of it, depending on your taste. I like it bold so I would use it all. Enjoy! Thanks for the 5 stars.

Can I use fresh peppers and onions instead of frozen?

Yes! Slice fresh veggies thin so they cook evenly with the salmon. Tossing them with a little oil helps prevent drying.

How do I keep salmon from drying out in the air fryer?

Cook at 350°F and start checking early. Salmon should reach 145°F and flake easily. Pull it as soon as it’s done — overcooking is the #1 cause of dry salmon.

Can I turn these into salmon tacos?

Absolutely. Use smaller tortillas, add a crunchy slaw mix, and finish with lime + salsa. It’s the same great flavor in a slightly more “taco night” vibe.
