1/2 teaspoon black pepper
1/2 teaspoon salt

Ingredient Notes

Salmon: Use fresh or fully thawed salmon fillets of similar thickness so they cook evenly. Skin-on or skinless fillets will work. If using frozen salmon, thaw it completely and pat it dry before seasoning.

Olive oil: A small amount helps the seasoning stick to the salmon and promotes better browning. You can substitute avocado oil or another neutral cooking oil.

Cajun seasoning: This is the main source of the recipe’s bold, savory flavor. Cajun blends can vary in salt and heat, so check the label before adding the extra salt.

Paprika: Paprika adds color and a mild, slightly sweet pepper flavor. Smoked paprika can be used if you want a deeper smoky taste.

Garlic and onion powder: These add savory flavor without making the seasoning mixture too heavy.

Black pepper: Adds a little extra warmth and complements the Cajun seasoning.

Fresh parsley: Parsley adds a fresh finish and brightens the rich seasoning.

Lemon: Fresh lemon juice adds acidity that balances the Cajun spices and salmon’s natural richness.

How to Make Air Fryer Cajun Salmon

Prepare the Salmon

Pat the salmon fillets dry with paper towels. Removing excess moisture helps the seasoning stick and encourages better browning in the air fryer.

Make the Seasoning

In a small bowl, combine the Cajun seasoning, paprika, garlic powder, onion powder, black pepper, and salt. Mix well.

If your Cajun seasoning is already quite salty, reduce or skip the additional salt.

Season the Salmon

Brush each salmon fillet lightly with olive oil. Sprinkle the seasoning mixture evenly over the top and gently press it onto the salmon so it sticks.

Try to cover the surface evenly without using an overly thick layer of seasoning.

Preheat the Air Fryer

Preheat your air fryer to 400°F (204°C) for about 3 minutes if your model recommends preheating.

Preheating helps the salmon start cooking immediately and can improve the texture of the outside.

Air Fry Until Cooked

Place the salmon fillets skin-side down in the air fryer basket. Leave a little space between each piece so the hot air can circulate.

Air fry at 400°F for 8–10 minutes, depending on the thickness of the fillets and your particular air fryer.

You generally do not need to flip salmon during cooking. Start checking it around 8 minutes. The salmon is ready when it flakes easily with a fork and reaches a safe internal temperature of 145°F (63°C) at the thickest part.

Serve and Enjoy

Carefully remove the salmon from the air fryer. Sprinkle with fresh parsley and serve with lemon wedges.

For the best texture, serve the salmon shortly after cooking while the edges are still nicely browned and the center is moist.

Serving Suggestions

Air Fryer Cajun Salmon works especially well with simple sides that balance its bold seasoning. Try serving it with steamed broccoli, roasted asparagus, green beans, or a fresh garden salad.

For a heartier meal, pair the salmon with white rice, brown rice, roasted potatoes, or mashed potatoes. A spoonful of fresh salsa or a light lemon-yogurt sauce can also add a refreshing contrast to the Cajun seasoning.

Recipe Tips

Pat the salmon dry first. Excess moisture can prevent the seasoning from browning nicely.
Do not overcrowd the basket. Leave space around the fillets for proper air circulation.
Don’t automatically flip the salmon. Salmon usually cooks well skin-side down without flipping.
Check the thickest part. Thicker fillets may need a few extra minutes.
Watch the salt. Cajun seasoning often contains salt, so taste the seasoning blend before adding extra.
Avoid overcooking. Salmon can become dry if left in the air fryer too long.
Use a thermometer when possible. Check the thickest part of the fillet for an accurate temperature.
Adjust for your air fryer. Air fryers vary in power, so cooking time can differ slightly between models.

Variations and Substitutions

Make It Spicier

For extra heat, add a pinch of cayenne pepper or use a hotter Cajun seasoning blend. You can also add a little crushed red pepper.

Add a Smoky Flavor

Replace the regular paprika with smoked paprika for a deeper, smoky flavor that pairs beautifully with Cajun seasoning.

Try Different Herbs

Parsley is a simple choice, but fresh cilantro, dill, or green onions can also work well.

Add a Sweet Glaze

For a sweet and spicy version, mix a small amount of honey with the olive oil before brushing it onto the salmon. Keep an eye on the salmon while cooking because the honey can brown quickly.

Use a Different Oil

Avocado oil can replace olive oil if preferred. Choose an oil that works well at high cooking temperatures.

Make It Dairy-Free

The recipe is naturally dairy-free as written, so no changes are necessary.

Storage and Reheating

Store leftover salmon in an airtight container in the refrigerator for up to 3 days.

To reheat, place the salmon in the air fryer at 350°F (177°C) for about 3–5 minutes, checking frequently so it does not dry out. Thicker pieces may need slightly longer.

Freezing cooked salmon is possible, although the texture may be slightly softer after thawing. For best quality, wrap individual portions tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
