What Ingredients are Best for Salmon Fajitas?

5 ingredients for salmon fajitas

If you want quick and simple salmon fajitas, you need an air fryer and only 5 ingredients. The only ingredients you need are 2-4 salmon fillets, avocado oil, 1 fajita seasoning kit, 12 ounce bag of frozen peppers and onion, and flour tortillas. You could also use corn tortillas instead.

Fajita Seasoning Substitute

I love to use a premade fajita seasoning mix because it cuts down the time. But if you don’t have a fajita seasoning kit, you can make this substitute instead.

Optional Homemade Fajita Seasoning:

  • 2 teaspoons chili powder
  • 1 teaspoon paprika
  • 1 teaspoon dried oregano
  • 1 teaspoon salt
  • 1 teaspoon sugar
  • ½ teaspoon cumin
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ¼ teaspoon cayenne pepper

Frozen Pepper and Onion Ingredient Substitute

Like the premade fajita seasoning, I love to use a frozen package of pepper and onions because it is so easy to throw into the air fryer. However, this is totally optional and you can use a real white or yellow onion and red bell pepper instead. If you go this route, use about ½ an onion and 1 red bell pepper, or any other bell pepper color of your choice.

Is an Air Fryer the Best Way to Cook Salmon?

What is the best way to cook salmon? Well, of course you could never beat smoked salmon or sometimes grilled salmon. But if you are looking for quick and quality salmon, then the air fryer is the best way to cook salmon. I’m sharing with you some really important tips for cooking salmon in the air fryer.

How Do You Keep Salmon From Sticking to the Air Fryer?

Tip #1: Make a foil sling. To make your salmon not stick to the air fryer, then you need to make a foil sling.

To make a foil sling, take a piece of foil the width of the foil is about ⅓ of the width of the air fryer basket. Place the foil in the air fryer basket and fold down the length of the foil so that it fits in the air fryer basket, but has handles so that you can pull it out of the air fryer basket after cooking. You will place the salmon on top of the foil sling. This will make cleaning up a breeze and the salmon will not stick to the basket.

If you don’t want to go the foil sling route, you could also use a piece of air fryer parchment paper, however the salmon may still stick to the paper if you don’t lightly spray it with avocado or olive oil. Plus, the foil sling makes it really easy to remove the salmon.

How to Make 10-minute Salmon Fajitas

Tip #2: Cook the salmon, peppers, and onions together in the air fryer. Cooking the salmon with the frozen peppers and onions will speed up the cooking process incredibly because you won’t need to cook them in batches.

To cook salmon fajitas in minutes, place the salmon on the foil sling and layer the onions and peppers around the salmon, in the air fryer basket. Then, lightly spray the contents with avocado oil. I love to use this Mistifi oil sprayer to spray avocado oil anytime I need oil for air fryer recipes. Then, sprinkle the fajita seasoning onto the salmon and vegetables. Rub a majority of the seasoning mixture onto the salmon.

What temp should salmon be cooked at?

Tip #3: Cook salmon in the air fryer basket at 350°F/175°C. Once the salmon and vegetables are covered in fajita seasoning- this is really going to make the fajitas taste amazing- set the air fryer to cook the salmon at 350°F/175°C.

You don’t need to preheat the air fryer to cook salmon in the air fryer. Yay! That’s just one of the many reasons I love the air fryer. Preheating is optional!

How long should salmon be cooked in the air fryer?

I love how incredibly fast this recipe is. Cook the salmon for 8-10 minutes in the air fryer at 350°F/175°C. Seriously, you can have dinner on the table in no time thanks to the air fryer!

How do you know when salmon is done in the air fryer?

Tip #4: Get an instant read thermometer. If you are a beginner to air fryer cooking, then you will want to check out this Air Fryer 101 guide. The number one thing you will learn as you experiment with cooking in the air fryer is that an instant read thermometer is incredibly important. It will help you know when your food is done cooking (baked goods included!)

Comments & Reviews

  • *** Using your recipe to make my own Fajita mix, do I use the entire seasoning mix to season the salmon?
    I know my husband and I will really love this which is why I gave it a 5 star rating. I trust your recipes because the ones that I have made have all turned out. My daughter and Granddaughter love your book and have also enjoyed the recipes that they have made.

    • 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.
