How to Cook Salmon in the Air Fryer: A Complete Guide for Perfectly Flaky, Juicy Results Every Time​

2025-11-09

Cooking salmon in the air fryer is one of the easiest, fastest, and most reliable ways to achieve restaurant-quality results at home. Whether you’re a beginner or a seasoned home cook, this method delivers tender, flaky flesh with a crispy, golden skin—all while using minimal oil. The key lies in understanding the science of heat distribution in air fryers, proper prep, and adjusting for variables like salmon thickness and your specific appliance. By following this step-by-step guide, you’ll master how to cook salmon in the air fryer consistently, avoiding common pitfalls like dryness, sticking, or undercooking.

Why Air Fryer Salmon Is a Game-Changer

Before diving into the “how,” let’s address the “why.” Air fryers work by circulating hot air at high speeds, mimicking deep frying but with little to no oil. For salmon, this means:

  • ​Speed: Cooks in 8–12 minutes vs. 15–20 minutes in an oven.

  • ​Crispiness: The air flow renders fat from the skin, creating a crunchy exterior without soggy bottoms.

  • ​Even Heating: Unlike stovetops (where heat can pool), air fryers distribute heat uniformly, reducing hot spots that burn edges.

  • ​Health: Uses 70–90% less oil than pan-searing, keeping salmon light yet flavorful.

  • ​Versatility: Works for fillets, steaks, or even whole small salmon (if your air fryer is large enough).

Step 1: Choose the Right Salmon

The foundation of great air fryer salmon starts with selecting the best fish. Here’s what to look for:

​Type of Salmon​

  • ​Wild vs. Farmed: Wild salmon (e.g., Sockeye, King) has a firmer texture and deeper flavor, while farmed (e.g., Atlantic) is milder and higher in fat—both cook beautifully in air fryers.

  • ​Fillets vs. Steaks: Fillets (boneless, skin-on or off) are easiest for beginners. Steaks (cross-sections with bone) add flavor but require slightly longer cooking.

  • ​Thickness Matters: Aim for fillets 1–1.5 inches thick. Thinner pieces (under 1 inch) risk overcooking; thicker ones (over 1.5 inches) may need extra time.

​Freshness Tips​

  • Buy from a trusted fishmonger; salmon should smell like the ocean, not “fishy.”

  • If using frozen, thaw overnight in the fridge (never at room temp). Pat dry with paper towels before cooking—excess moisture steams the fish instead of crisping it.

Step 2: Prep the Salmon for Optimal Results

Preparation is where many home cooks go wrong. Follow these steps to set your salmon up for success:

​Pat It Dry​

Use paper towels to thoroughly dry both sides of the salmon. Moisture is the enemy of crispiness—even a thin film will prevent the air fryer from browning the skin.

​Season Generously (But Simply)​​

Overcomplicating seasoning can clash with the salmon’s natural flavor. Stick to basics:

  • ​Oil: Brush 1 tsp olive oil (or avocado oil) on the top (non-skin side) to promote browning. Avoid spraying—too much oil causes smoking.

  • ​Salt: Sprinkle coarse sea salt or kosher salt just before cooking. Salting too early draws out moisture, leading to dryness.

  • ​Pepper & Herbs: Freshly cracked black pepper, dill, parsley, or a pinch of red pepper flakes add brightness without overpowering.

  • ​Optional Extras: For bold flavors, try lemon zest, garlic powder, or a paste made from Dijon mustard and honey (apply sparingly to avoid burning).

​Skin-On or Skin-Off?​​

Leaving the skin on is ideal—it acts as a protective barrier, keeping the flesh moist. The skin will crisp up beautifully if the salmon is patted dry and placed skin-side down. If using skin-off fillets, be extra careful not to overcook.

Step 3: Master the Air Fryer Settings

Every air fryer is slightly different, but these guidelines will work for most models (1200–1800W):

​Temperature & Time​

  • ​Preheat: Always preheat your air fryer to 180°C (360°F) for 3–5 minutes. Preheating ensures even cooking from the start.

  • ​Cook Time: For 1-inch thick fillets, cook 8–10 minutes. For 1.5-inch fillets, aim for 10–12 minutes. Thinner pieces (0.75 inches) need 6–7 minutes.

  • ​Check Doneness: The internal temperature should reach 63°C (145°F) for medium (still slightly translucent in the center) or 71°C (160°F) for well-done. Use an instant-read thermometer inserted into the thickest part.

​Placement & Space​

  • Place the salmon skin-side down in the air fryer basket. If cooking multiple fillets, arrange them in a single layer with space between—overcrowding traps steam and leads to uneven cooking.

  • For extra crispiness, you can place a wire rack inside the basket (set the salmon on top). This allows air to circulate all around, mimicking a convection oven.

Step 4: Pro Tips to Avoid Common Mistakes

Even with perfect prep, small missteps can ruin your salmon. Here’s how to troubleshoot:

​Sticky Basket? No More.​​

  • Lightly coat the basket with avocado oil spray or line it with parchment paper (cut to fit, with holes poked for air flow). Avoid non-stick sprays with high smoke points—they can damage the basket over time.

  • After cooking, let the basket cool, then wipe with a damp cloth. Never use steel wool; it scratches the non-stick coating.

​Dry Salmon? Adjust These Factors.​​

  • ​Thickness: Thinner fillets cook faster—set a timer and check early.

  • ​Overcooking: Remove salmon at 63°C (145°F); residual heat will carry it to 68°C (155°F), which is still juicy.

  • ​Brining (Optional)​: For extra moisture, brine thin fillets for 15 minutes in a solution of ¼ cup salt + 4 cups water, then rinse and pat dry.

​Skin Not Crispy?​​

  • Ensure the skin is completely dry before cooking.

  • Press the salmon gently onto the basket with a spatula to ensure contact—air can’t crisp a loose piece.

  • If the skin is still soft, broil for 1–2 minutes at the end (watch closely to avoid burning).

Step 5: Serving & Pairing Ideas

Once your salmon is cooked, let it rest for 2–3 minutes before serving. This allows juices to redistribute, preventing them from spilling out when you flake the fish.

​Classic Pairings​

  • ​Veggies: Roasted asparagus, broccoli, or zucchini (toss with olive oil, salt, and pepper; air fry alongside the salmon at 180°C for 10–12 minutes).

  • ​Starches: Quinoa, mashed cauliflower, or crusty bread to soak up pan juices.

  • ​Sauces: Lemon-dill sauce (mix Greek yogurt, lemon juice, dill, and garlic), teriyaki glaze, or a drizzle of chili crisp.

​Garnishes​

Fresh herbs (dill, chives), lemon wedges, or a sprinkle of flaky sea salt add brightness and texture.

Step 6: Troubleshooting: What If…?

  • ​Salmon Sticks to the Basket: You likely didn’t dry it enough or used too much oil. Next time, pat thoroughly and use a light oil spray.

  • ​It’s Overcooked: Reduce time by 1–2 minutes next round. Use a thermometer to avoid guesswork.

  • ​Skin Is Rubbery: The salmon was probably too cold when it went in. Let it sit at room temp for 10 minutes before cooking.

Nutritional Benefits of Air Fryer Salmon

Beyond taste, air fryer salmon is a nutritional powerhouse:

  • ​Omega-3 Fatty Acids: Supports brain health, reduces inflammation, and lowers heart disease risk.

  • ​High-Quality Protein: A 4-oz serving provides 25g of protein, ideal for muscle repair.

  • ​Vitamins & Minerals: Rich in vitamin D, B12, selenium, and astaxanthin (an antioxidant that gives salmon its pink color).

Final Thoughts: Practice Makes Perfect

Cooking salmon in the air fryer is as much about technique as it is about following a recipe. Pay attention to thickness, preheat your appliance, and adjust time based on your model. With a little practice, you’ll consistently turn out flaky, juicy salmon that impresses family and friends.
