For today’s Friday Favorites pick I’m reminding you about this amazing Air Fryer Salmon Recipe served with Mustard-Herb Sauce, and this is one of the tastiest recipes I’ve ever made for an easy low-carb dinner! 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 Air Fryer Salmon cooks but trust me, you MUST make the 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!

Why is Air Fryer Salmon a great method for cooking Salmon?
Fish literally cooks in minutes in the Air Fryer, and besides being quick it’s so easy and almost foolproof if you’re careful not to overcook the fish. And if you’re cooking in the summer, using this method will keep your kitchen cool.
How low in carbs is the Air Fryer Salmon Recipe?
This recipe for Air Fryer Salmon with Mustard Herb Sauce is not only amazingly delicious, but it only has about 1 net carb per serving!
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 with Air Fryer 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:
(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

Thaw salmon overnight in the fridge if frozen.
Drain salmon and pat dry. Then rub each piece with olive oil and Szeged Fish Rub (affiliate link) or your favorite fish rub.
Put salmon on the air fryer rack and let it come to room temperature while you make the sauce.
Finely chop green onions and fresh parsley for the sauce.
Then whisk together sour cream, mayo, Dijon mustard, chopped parsley, chopped green onion, and dried dill.
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.)
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 Glazed Salmon with Dijon Mustard Sauce at Beyond Salmon.
