How Long to Air Fryer Salmon at 400

Air fryer salmon is one of my go-to busy weeknight dinners because it only takes 10 minutes to cook in a preheated air fryer at 400 degrees F. I always recommend placing salmon or any other fish skin-side down in the air fryer. I find this cooks the fish more evenly and also makes it easier to remove from the air fryer once it’s ready. I cook salmon in the air fryer at 400 degrees F. This helps the skin get crispy without drying out the fillets. It is done when it reaches a temperature of 145 degrees F. To reheat salmon in the air fryer, I preheat the air fryer to 370 degrees F, then cook the fish skin-side down for about 4 minutes or until it’s heated all the way through. When I’m cooking salmon in the air fryer, I usually don’t flip it. It cooks beautifully without it, plus it’s easier! The only time I flip salmon is when I’m cooking it with the skin on and want extra crispy skin, and then I’ll flip it with 3-4 minutes left in the cooking time.

Salmon is a fantastic choice for a quick, healthy, and flavorful meal, and using an air fryer at 400°F makes it even easier to achieve restaurant-quality results at home. The air fryer’s high-heat circulation creates a crispy exterior while keeping the interior moist and flaky, all in a fraction of the time it takes to bake or pan-sear. But how long should you cook salmon at 400°F, and what factors influence the timing? Let’s dive into the details to ensure your salmon comes out perfectly every time.

Why Use an Air Fryer for Salmon?

The air fryer is a game-changer for cooking salmon because it combines speed, ease, and excellent texture. Unlike traditional frying, which uses a lot of oil, air fryers rely on hot air circulation to mimic the crispiness of fried food with minimal oil. This makes it a healthier option without sacrificing flavor. The even heat distribution ensures the salmon cooks uniformly, avoiding the common pitfalls of overcooking or uneven doneness. Plus, cleanup is a breeze—especially if you line the basket with parchment paper or foil, as suggested by Well Plated.

Factors Affecting Cooking Time

The time it takes to air fry salmon at 400°F depends on several variables:

Thickness of the Fillets: Thicker fillets ( inches or more) may need 10-12 minutes, while thinner ones (around 1 inch) can be done in 6-8 minutes.

Skin-On vs. Skinless: Skin-on salmon tends to cook more evenly because the skin acts as a barrier, protecting the flesh from direct heat. Skinless fillets may require slightly less time to avoid drying out.

Fresh vs. Frozen: Fresh or fully thawed salmon cooks faster than frozen. If using frozen salmon, you’ll need to add 5-7 minutes to the cooking time, often starting with a few minutes to thaw in the air fryer before seasoning.

Air Fryer Model: Different air fryers vary in wattage and airflow. Basket-style air fryers may cook slightly faster than oven-style models, so always check for doneness early.

Desired Doneness: The FDA recommends an internal temperature of 145°F for fully cooked salmon, but many prefer it medium (130-135°F) for a juicier texture, allowing it to rest and finish cooking off the heat.

Step-by-Step Guide to Air Frying Salmon at 400°F

Here’s how to get perfectly cooked salmon in your air fryer:

Tips for Success

Use a Thermometer: A meat thermometer is the most reliable way to avoid overcooking. Insert it into the thickest part of the fillet to check the temperature.

Avoid Overcrowding: Ensure there’s space between fillets for proper air circulation, which is key to achieving that crispy exterior.

Experiment with Flavors: Beyond basic seasonings, try a teriyaki glaze, a honey-garlic mix, or even a spicy Cajun rub for variety. Apply sweet glazes toward the end of cooking to prevent burning.

Frozen Salmon Hack: If cooking from frozen, start by air frying at 400°F for 5 minutes to thaw, then season and continue cooking for 5-7 more minutes, as suggested by Cotter Crunch.

Easy Cleanup: Line the basket with parchment paper or foil to minimize mess, especially for skinless fillets that might stick.

Common Mistakes to Avoid

Overcooking: Check early to prevent dry salmon. It’s better to undercook slightly and add more time if needed.

Skipping the Pat-Down: Excess moisture can make the salmon steam instead of crisp, so always pat it dry.

Overloading Seasonings: Too much seasoning, especially salt, can overpower the salmon’s natural flavor. Start light and adjust to taste.

Ignoring Air Fryer Variations: Since models differ, use the suggested times as a guide and adjust based on your machine’s performance.

Serving Suggestions

Air fryer salmon pairs beautifully with a variety of sides. For a light meal, try a green salad with a citrus vinaigrette or sautéed greens like spinach or kale. For something heartier, roasted potatoes or quinoa add substance without overwhelming the dish. You can also cook air fryer asparagus or green beans at 400°F for 2-4 minutes before adding the salmon, making it a one-appliance meal.

Storage and Reheating

Leftover salmon can be stored in an airtight container in the fridge for up to 3 days or frozen for up to 2 months. To reheat, use the air fryer at 370°F for 3-4 minutes or gently warm in a skillet over medium heat to avoid drying it out. Cold leftover salmon is also great flaked over salads or mixed into a creamy dip.

Cooking salmon in an air fryer at 400 degrees Fahrenheit is a convenient and healthy way to enjoy this delectable fish. By following the recommended timing and proper preparation, you can achieve flawless results without the need for excessive oil. The crispy exterior and tender, flavorful interior of air-fried salmon will undoubtedly impress your taste buds. So why not give it a try and add a new twist to your salmon recipes? Your taste buds and health will thank you!
