How to Make Cajun Air Fryer Salmon with Zucchini

The steps for making this air fryer salmon recipe are short and sweet. You almost don’t need them – it’s all super intuitive. Here’s how to make it:

  • Season the Veggies. Start by preheating the air fryer to 400°F. Then combine the onion, zucchini, and half of the oil in a bowl, sprinkle in some salt and pepper, and transfer the mixture into the air fryer basket.
  • Air-Fry the Veggies. Make sure the vegetables are in an even layer, and cook them for 6-7 minutes, giving the basket a shake halfway through.
  • Season and Cook the Fish. Once the veggies are nicely cooked, set them aside. In the same bowl, toss the salmon with the remaining oil and Cajun seasoning. Place the seasoned salmon in the air fryer and cook for 5-6 minutes, or until it’s thoroughly cooked.
  • Enjoy! Now it’s time to plate up! Divide the flavorful salmon and veggies onto plates, and serve hot.

Air Fryer Salmon Recipe FAQs

Do You Put Skin Side Up or Down When Air Frying Salmon?

For this recipe, I like to use skinless salmon, but you could use skin-on salmon if you like. To get a crispy skin, you would want to cook it skin-side-down first, and then flip the pieces to cook skin-side-up. In general, you want to crisp up salmon skin, so always expose it to the heat during cooking, and rotate it as needed so it cooks evenly.

Why Does My Salmon Turn White in the Air Fryer?

If you’ve ever made salmon in the air fryer before, you might have noticed some white stuff forming on the surface during the cooking process. But don’t worry – it’s just a natural protein called albumin. Drying the salmon before coating and cooking it can prevent the albumin from seeping out during the cooking process. Still, if you see this, it’s no problem! You can wipe it off with a paper towel if you like, or leave it as-is.

How Long Should You Cook Salmon in the Air Fryer?

It takes just minutes to cook salmon in the air fryer. This air fryer salmon recipe cooks at 400°F for about six minutes, but if you’re not sure that the salmon is done, just use the “flake” test. Twist a fork gently in the thickest part of the salmon. If it flakes apart easily, it’s done. If it sticks stubbornly together, it needs another minute or two (or three). This will depend on how thick your salmon is, how cold it is, etc.

Tips for Success

These helpful tips will ensure that your cajun air fryer salmon turns out perfect. Keep them in mind, and enjoy every bite!

  • Pat Dry: Pat the salmon fillets dry with a paper towel before tossing them in the Cajun seasoning. This step removes excess moisture, helping the spices stick well and giving the salmon an irresistible, crispy finish.
  • Even Slices: When cutting the zucchini, aim for even slices, to get that ideal tenderness and a slight crunch.
  • Preheating: While some recipes don’t call for preheating the air fryer, I find that it gives consistent results. Plus, it takes such a short amount of time! Just a few minutes will do the trick.
  • Frequent Checks: Keep an eye on the cooking process. Fish cooks quickly, and air fryers can vary, so check for doneness a little early to avoid overcooking.

What to Serve with this Cajun Air Fryer Salmon Recipe

To complement the Cajun spices here, I like to serve classic Southern side dishes. Need some recipes? These would be perfect:

  • Cornbread: Everyone loves sunny, yellow cornbread, but this Sweet Potato Cornbread takes it over the top. The touch of healthy sweetness is perfect with this spicy air fryer salmon recipe.
  • Potato Salad: Creamy, tangy Red White and Blue Potato Salad is easy to make with colorful fingerling potatoes, or any potatoes you like.
  • Succotash: Spicy Corn Succotash is a summery side dish that goes with everything, especially zucchini and salmon!

How to Store and Reheat Leftovers

If you have leftovers, you can store them in the refrigerator for 2 – 3 days. Let the salmon and zucchini cool to room temperature (but don’t leave them out for more than one hour!) before refrigerating in airtight containers or food storage bags.

Reheat in the air fryer for just a minute or two, until heated through. Don’t overcook the dish or the salmon will be tough!

Will This Air Fryer Salmon Recipe Freeze Well?

To be honest, the textures will change a bit if you freeze and thaw the salmon and zucchini. However, it will still be totally safe to eat. Just cool the dish, and pack it into freezer-safe containers or bags. Mark with the date, freeze, and use within 1-2 months for the best quality. It’s best to thaw this in the fridge before reheating.
