Ingredients

Gathering the right ingredients is key to achieving delicious air fryer salmon that’s cooked perfectly at 400°F. Here’s what you’ll need for a simple, flavorful preparation.

Salmon

• 2 salmon fillets (6 ounces each, skin-on or skinless)
• Make sure the fillets are fresh or properly thawed if frozen
• Pat fillets dry with a paper towel for a crispier finish

Seasonings

• 1 teaspoon olive oil (or your preferred cooking oil)
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ½ teaspoon paprika (optional, adds smokiness)

• Lemon wedges for serving
• 1 teaspoon garlic powder or minced garlic for added flavor
• Fresh dill or parsley for garnish
• 1 teaspoon honey or maple syrup for a touch of sweetness

Tools And Equipment

To cook salmon perfectly in an air fryer at 400°F, you’ll need the right tools and equipment. Gather these essentials to ensure a smooth and efficient cooking process.

Air Fryer

An air fryer is the centerpiece for this recipe. Choose an air fryer with a basket large enough to hold your salmon fillets without overcrowding. Ensure it has adjustable temperature controls and a timer for precise cooking at 400°F. Models with non-stick baskets make cleanup easier and prevent the salmon from sticking.

• Tongs or a Spatula: Use heat-resistant tongs or a spatula to handle the salmon safely when transferring it into or out of the air fryer.
• Brush: A silicone brush helps evenly coat the salmon with olive oil or honey/maple syrup for a perfectly golden exterior.
• Meat Thermometer: To achieve tender and flaky salmon, use a meat thermometer to check if the internal temperature reaches 145°F, the USDA’s recommended safe temperature for cooked salmon.
• Parchment Paper: Optional but useful for lining the air fryer basket to prevent sticking and make cleanup simpler. Choose air fryer-safe parchment paper with pre-punched holes for proper airflow.

Directions

Follow these clear and simple steps to cook salmon in your air fryer at 400°F. With proper preparation and timing, you’ll achieve tender, flavorful salmon every time.

Prep The Salmon

1. Rinse the salmon fillets under cold water and pat them dry with paper towels.
2. Check for pin bones by running your fingers over the flesh; remove any with tweezers for a smooth fillet.
3. If the skin is still on, leave it intact to help retain moisture during cooking.

Season The Salmon

1. Drizzle the salmon fillets with 1 tablespoon of olive oil, ensuring a thin and even coating on all sides.
2. Sprinkle evenly with salt, black pepper, and 1 teaspoon of paprika for a smoky flavor.
3. Add a light dusting of garlic powder or spread 1 teaspoon of minced garlic across the top.
4. For added sweetness, brush 1 teaspoon of honey or maple syrup over each fillet.
5. Garnish with freshly chopped dill or parsley for a fragrant finish.

1. Set your air fryer to 400°F and allow it to preheat for 3-5 minutes.
2. If needed, place parchment paper or a liner in the basket to prevent sticking.
3. Ensure the basket is clean and dry for even cooking.

Cook The Salmon

Cooking salmon in an air fryer at 400°F ensures a golden, crisp exterior and tender interior. Follow these steps to achieve perfectly cooked salmon every time.

Cooking Temperature

Set your air fryer to 400°F. This high temperature helps create a deliciously crispy exterior while locking in the natural moisture inside the fillet. Use your air fryer’s preheat function to ensure consistent cooking.

Cooking Time

Place the seasoned salmon fillets in the air fryer basket, skin side down if applicable. Cook for 7 to 10 minutes, depending on the thickness of your fillets. For thinner cuts (under 1 inch thick), 7 minutes typically suffices, while thicker pieces may require up to 10 minutes. Always keep an eye on the salmon during the last few minutes to avoid overcooking.

Thickness of Salmon	Cooking Time at 400°F
Under 1 inch	7 minutes
1 inch or thicker	8 to 10 minutes

Checking For Doneness

Use a meat thermometer to check if the salmon has reached an internal temperature of 145°F, as recommended by the USDA. Insert the thermometer into the thickest part of the fillet. If you don’t have a thermometer, test the doneness by pressing gently with a fork. Fully cooked salmon will flake easily and appear opaque with a slight pink center. Adjust cooking time in 1-minute intervals if needed.

Tips For Perfectly Cooked Salmon

Cooking salmon in an air fryer at 400°F is simple when you follow a few key strategies. These tips will help you achieve consistently tender, flavorful, and perfectly cooked salmon every time.

Choosing The Right Salmon

Select fresh, high-quality salmon fillets for the best results. Look for fillets with vibrant color and a firm texture. Wild-caught salmon is often more flavorful, while farm-raised salmon tends to be milder and richer in fat. Choose fillets of even thickness to ensure consistent cooking—about 1-inch thickness works well for air frying. Decide between skin-on or skinless fillets based on preference, but keeping the skin on can help the salmon retain moisture during cooking.

Avoiding Overcooking

Prevent overcooking by closely monitoring the air frying time. Use a meat thermometer to check the internal temperature of the salmon; it should reach 145°F in the thickest part. If you don’t have a thermometer, test the salmon by gently flaking it with a fork—properly cooked salmon will separate easily and have an opaque appearance. Adjust the timing in small increments, such as 1 minute, if needed, especially for thinner or thicker fillets. Removing the salmon from the air fryer as soon as it’s done and allowing it to rest for a couple of minutes maintains its juiciness.

Serving Suggestions

Enhance your salmon with thoughtful accompaniments. Serve it alongside roasted vegetables, green salads, or steamed rice for a complete meal. Add a squeeze of fresh lemon juice or a drizzle of honey glaze just before serving to boost flavor. Pair it with light sauces like dill yogurt or a simple garlic butter sauce for added richness. For a garnish, sprinkle fresh herbs like parsley, dill, or chives to provide a pop of color and freshness.

Make-Ahead And Storage

Preparing your salmon ahead of time or storing leftovers properly ensures you enjoy the same fresh and delicious taste even after reheating. Follow these simple tips to store and reheat your air-fried salmon effectively.

How To Store Leftovers

• Allow the salmon to cool to room temperature before storing to prevent moisture buildup.
• Place the salmon in an airtight container or wrap it tightly with plastic wrap or aluminum foil to maintain freshness.
• Store it in the refrigerator for up to 3 days. Use a label to keep track of the storage date.
• For longer storage, transfer the salmon to a freezer-safe container or freezer bag. It can be frozen for up to 1 month for optimal quality.

• For reheating in the air fryer, preheat the air fryer to 350°F. Place the salmon in the basket and heat for 3-4 minutes, checking for a warm interior.
• If using a microwave, place the salmon on a microwave-safe plate. Cover it with a microwave-safe lid or damp paper towel. Heat on medium power in 30-second intervals until warmed through, avoiding overheating to prevent drying out.
• Alternatively, reheat in the oven at 300°F for about 10-12 minutes. Wrap the salmon in foil to help retain moisture.

Conclusion

Cooking salmon in an air fryer at 400°F is a game-changer for preparing a quick, healthy, and flavorful meal. With the right ingredients, tools, and timing, you can achieve perfectly cooked salmon that’s tender, crisp, and full of natural flavor.
