Ingredients for Garlic Butter Salmon in the Air Fryer

For the Salmon Fillets:
- 2 salmon fillets (6 oz / 170g each), skin-on or skinless
- 1 tablespoon olive oil
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon smoked paprika
- 1/4 teaspoon onion powder
For the Garlic Butter Sauce:
- 3 tablespoons unsalted butter, melted
- 3 garlic cloves, finely minced (fresh is best!)
- 1 tablespoon fresh lemon juice
- 1 tablespoon fresh parsley, finely chopped
- 1/4 teaspoon red pepper flakes (optional, for a little heat)
- Lemon wedges, for serving
Pro Tip: Use center-cut salmon fillets of even thickness for the most consistent cooking. Avoid very thin tail-end pieces — they’ll cook faster and can dry out.
Equipment You’ll Need
- Air fryer (basket or oven-style both work)
- Small mixing bowl for the garlic butter
- Pastry brush or spoon for basting
- Meat thermometer (optional but highly recommended)
- Tongs for removing fillets
How to Make Garlic Butter Salmon in the Air Fryer: Step by Step

Step 1: Prepare the Garlic Butter Sauce
In a small bowl, combine the melted butter, minced garlic, lemon juice, parsley, and red pepper flakes if using. Stir well and set aside. This is your flavor bomb — you’ll use it before and after cooking.
Step 2: Season the Salmon
Pat the salmon fillets completely dry with paper towels. This is important — removing excess surface moisture helps the seasoning stick and prevents steaming.
Drizzle or brush olive oil over both sides of each fillet. Mix together the salt, pepper, garlic powder, smoked paprika, and onion powder, then sprinkle evenly over the top of the salmon.
Step 3: Preheat the Air Fryer
Preheat your air fryer to 400°F (200°C) for 3 minutes. Preheating is a small step that makes a real difference — it ensures the salmon starts cooking immediately and develops a nicer exterior.
Step 4: Brush with Garlic Butter
Spoon or brush half of the garlic butter generously over the top of each seasoned salmon fillet. Don’t hold back here — this is what makes the recipe so irresistible.
Step 5: Air Fry the Salmon
Lightly spray the air fryer basket with cooking spray or brush with a little oil to prevent sticking. Place the salmon fillets skin-side down in the basket, leaving space between each piece for airflow.
Air fry at 400°F (200°C) for 8–10 minutes. You do not need to flip the salmon. Cooking time depends on thickness:
- 3/4 inch thick fillets: 7–8 minutes
- 1 inch thick fillets: 9–10 minutes
- 1.25 inch thick fillets: 11–12 minutes
Step 6: Check for Doneness
The salmon is done when it reaches an internal temperature of 125°F–130°F (52°C–54°C) for medium, or 145°F (63°C) for fully cooked. It should flake easily when pressed gently with a fork.
Pro Tip: Pull the salmon out 1–2 minutes before it looks fully done. Residual heat continues cooking it as it rests.
Step 7: Add More Garlic Butter and Serve
Remove the salmon from the air fryer and immediately spoon the remaining garlic butter sauce over the top. The heat from the salmon will melt it right in. Finish with fresh parsley and a squeeze of lemon. Serve right away!
Tips for Cooking Garlic Butter Salmon Perfectly in the Air Fryer
These are the little details that take your air fryer salmon from good to absolutely outstanding:
1. Always Pat the Salmon Dry First
Moisture on the surface of the fish causes steaming instead of crisping. A quick pat with paper towels takes 10 seconds and makes a noticeable difference in texture.
2. Don’t Skip the Preheat
Starting in a cold air fryer means uneven cooking. Three minutes of preheating is all it takes to ensure the exterior gets that beautiful golden color from the moment it hits the basket.
3. Use Fresh Garlic, Not Jarred
Fresh minced garlic in the butter sauce is genuinely worth the extra minute it takes. It has a more aromatic, less acidic flavor than jarred garlic, and it makes the whole dish smell incredible.
4. Don’t Overcrowd the Basket
Air fryers cook by circulating hot air around the food. If you stack or crowd the basket, you’ll end up steaming the salmon instead. Leave at least half an inch of space between fillets, and cook in batches if needed.
5. Use a Thermometer for Perfect Results
Timing is a guideline, but every air fryer and every piece of salmon is slightly different. A meat thermometer removes all the guesswork and guarantees you pull it out at exactly the right moment.
6. Let It Rest for 2 Minutes
Just like a steak, salmon benefits from a short rest after cooking. The juices redistribute and the internal temperature stabilizes. Two minutes is all it needs.
Pro Tip: If your air fryer runs hot, check at 7 minutes. If it tends to run cool, add a minute. You’ll get to know your machine after the first couple of tries.

FAQ: Garlic Butter Salmon in the Air Fryer
How long to cook salmon in the air fryer at 400°F?
At 400°F (200°C), a 1-inch thick salmon fillet takes 9–10 minutes. Thinner fillets (3/4 inch) take 7–8 minutes. Always check with a thermometer — internal temp of 125°F–130°F for medium, or 145°F for fully cooked.
Do I need to flip salmon in the air fryer?
No! That’s one of the best things about this method. The hot circulating air cooks the salmon from all sides, so there’s no need to flip. Just place it skin-side down and let the air fryer do its thing.
Should I use skin-on or skinless salmon fillets?
Either works great. Skin-on fillets are slightly easier to handle and the skin protects the bottom from overcooking. If you prefer skinless, that’s completely fine — just reduce the cook time by about 1 minute.
Can I cook frozen salmon in the air fryer?
Yes! Rinse the frozen fillets under cold water, pat dry, season, and add 4–5 extra minutes to the cook time. The result will be slightly less juicy than thawed salmon, but it’s a solid option when you’re in a pinch.
Why is my air fryer salmon sticking to the basket?
This usually happens when you skip the oil spray. Always lightly coat the basket with cooking spray or brush it with oil before placing the salmon. You can also use parchment paper liners made for air fryers.
Can I make this recipe dairy-free?
Absolutely. Swap the butter for vegan butter or simply use extra olive oil mixed with the garlic, lemon, and herbs. The flavor is slightly different but still delicious.
