Air Fryer Salmon with Mustard-Herb Sauce was one of the tastiest recipes I’ve ever made for an easy low-carb dinner, and it made me wonder why it has taken me so long to cook salmon in the Air Fryer! And our salmon pieces (which were slightly small) were perfectly cooked in six minutes!

So even with the time for the salmon to come to room temperature this is one of the quickest and easiest dinners you can imagine. You’ll barely have time to make the Mustard-Herb Sauce while the salmon cooks but trust me, you MUST make this sauce.

The creamy, slightly mustardy sauce with sour cream, mayo, Dijon mustard, lemon juice, chopped parsley, chopped green onion, and dried dill was so delicious on the salmon. The other thing that made this recipe so tasty was the Szeged Fish Rub (affiliate link) I rubbed on the salmon.; I’ve used that for so many years that now I can’t even imagine cooking fish without using it.

 And just how good was this salmon? I ate a piece of leftover cold salmon with the sauce for breakfast two days in a row!

What ingredients do you need for this recipe?

Why is the Air Fryer such a great way to cook Salmon?

Fish literally cooks in minutes in the Air Fryer, and besides being quick it’s so easy. And if you’re cooking in the summer, using the Air Fryer will keep your kitchen cool.

Which Air Fryer Did I Use?

The Cuisinart Convection Air Fryer Toaster Oven (affiliate link) is the one I used for this recipe. This air fryer has a larger basket, which lets me fit four pieces of salmon (it would probably hold six), and I find this model very easy to use. I also like the convenience of having an air fryer that stays out on the counter.

What if you don’t have an Air Fryer?

I’m not trying to convince you to buy an air fryer; you can use the old printer-friendly recipe for Broiled Wild Salmon with Mustard-Mint-Parsley Sauce to cook this in the oven or toaster oven.

What other sauces could you serve on this salmon?

I love sauce on fish and if you don’t make the mustard-herb sauce I’d happily eat this salmon with my Double-Dill Homemade Tartar Sauce, Tzatziki Sauce, or Market Street Grill Creamy Cucumber Sauce for Fish.

How to Make Air Fryer Salmon with Mustard-Herb Sauce:

(Scroll down for complete recipe with nutritional information.)

  1. Thaw salmon overnight in the fridge if frozen.
  2. Drain salmon and pat dry. Then rub each piece with olive oil and 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.
  6. Cook the fish 6 minutes in the Air Fryer, 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.)
  7. Serve salmon hot, with Mustard-Herb Sauce on the side.

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

 

Ingredients

  • 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

Instructions

  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.

Notes

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. I used Szeged Fish Rub (which I absolutely LOVE), but use your favorite seasoning blend for fish (affiliate link).

The inspiration for this recipe came from Broiled Wild Salmon with Mustard-Mint-Parsley Sauce, which was adapted from Glazed Salmon with Dijon Mustard Sauce at Beyond Salmon. You can use that recipe if you'd prefer broiled salmon cooked in the oven or the toaster oven.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Air Fryer Salmon with Mustard-Herb Sauce is a great dish for low-carb or Keto diet plans, and for any phase of the original South Beach Diet. For the sauce South Beach would recommend light sour cream and light mayo, or use all sour cream if you prefer and it will still be good.
