This Easy Low-Carb Air Fryer Salmon with Mustard-Herb Sauce was one of the tastiest recipes I’ve made all summer and it made me wonder why it has taken me so long to cook salmon in the Air Fryer! I guess I thought it might be a little boring, but I promise you this is not even the tiniest bit boring! 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.

In fact, you’ll barely have time to make the Mustard-Herb Sauce but trust me, you MUST make this sauce. Of course I love sauce on fish and I’d happily eat this salmon with my Ultra Easy Double-Dill Diet-Friendly Tartar Sauce, Tzatziki Sauce, or Market Street Grill Creamy Cucumber Sauce for Fish as well. But this 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 the salmon so tasty is the beloved Szeged Fish Rub that I’ve mentioned many times on the blog. I’ve used that for so many years that now I can’t even imagine cooking fish without using it.

I know some people don’t have an Air Fryer and don’t want to buy one, so if you want to make this in the oven or toaster oven you can check out Broiled Wild Salmon with Mustard-Mint-Parsley Sauce, which is the long-ago recipe that inspired this one. Have fun seeing how my food photography skills have improved since 2007! 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!

Which Air Fryer Did I Use?

When Air Fryers started to be a thing, I first bought a NuWave Air Fryer and used it to make Air Fryer Spicy Sweet Potato Fries. Then I discovered the Cuisinart Convection Air Fryer Toaster Oven which 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. I’m not trying to convince you to buy an air fryer; you can follow the cooking instructions for Broiled Wild Salmon with Mustard-Mint-Parsley Sauce to cook this in the oven or toaster oven.

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

(This is just a summary of the steps shown in the photos above. Scroll down for complete recipe.)

  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 (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.

The fish is shown with Easy Low-Carb Cucumbers Caesar, which is about perfect for an easy summer side dish. This would also be delicious with Spicy Tomato-Cucumber Salad with Peperoncini or Low-Carb Spicy Mexican Slaw.

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

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

 

Ingredients:

Salmon Ingredients:

  • 4 salmon fillets, thawed if frozen
  • olive oil, for rubbing on salmon (see notes)
  • fish rub, for rubbin on salmon (see notes.)

Sauce Ingredients

  • 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

Directions:

  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 (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.

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:
Easy Low-Carb Air Fryer Salmon with Mustard-Herb Sauce is a great dish for low-carb diet plans, and for any phase of the 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.
