Easy Low-Carb Air Fryer Salmon with Mustard-Herb Sauce is one of the tastiest things I’ve cooked in the Air Fryer!

Easy Low-Carb Air Fryer Salmon with Mustard-Herb Sauce


  • 4 salmon fillets, thawed if frozen

  • 4 tsp. olive oil, for rubbing on salmon (see notes)

  • 2 tsp. fish rub, for rubbing on salmon (see notes.)

  • 1/4 cup sour cream

  • 3 T mayo

  • 1 T Dijon mustard, or slightly more (Start with one tablespoon, then taste to see if you want a bit more.)

  • 1 T lemon juice

  • 1 T finely chopped fresh parsley

  • 1 T finely chopped green onion

  • 1/2 tsp. dried dill weed


  1. Thaw salmon overnight in the fridge if frozen.

  2. When you’re ready to cook, drain salmon and pat dry if needed. Then rub each piece with a small amount of olive oil and then with Szeged Fish Rub (affiliate link) (or your favorite fish rub.)

  3. Put salmon on the air fryer rack and let it come to room temperature while you make the sauce.

  4. Finely chop green onions and fresh parsley for the sauce.

  5. Then whisk together sour cream, mayo, Dijon mustard, chopped parsley, chopped green onion, and dried dill. Taste sauce and see if you want a little more Dijon Mustard.

  6. Set Air Fryer to 400F/200C.

  7. Cook the fish 6 minutes, then check for doneness by pressing down on the fish with a finger. It should feel barely firm but not hard when it’s done. (Our salmon pieces are quite small so thicker fish might take a minute or two longer to cook.)

  8. Serve salmon hot, with Mustard-Herb Sauce on the side.


Even though the air fryer can cook without oil, using some oil helps the fish rub stick and keeps the salmon moist. Just use enough oil to barely moisten the surface of the fish.
