Sometimes the evening sneaks up on you, and you want something that feels a bit special but doesn’t eat up your whole night. This air fryer salmon with Dijon mustard and Old Bay seasoning hits that sweet spot — it’s fast, flavorful, and a little unexpected in its punch of tang and spice.
I remember the other night, I tossed this together while half-listening to a podcast and almost forgot about the salmon in the air fryer (classic me). That moment when I pulled it out and saw the crispy edges was totally worth the minor kitchen distraction. The aroma of mustard and that familiar Old Bay seasoning pulled me right back in. The salmon was tender and flaky, with just the right amount of crispy skin to make every bite interesting. It wasn’t fancy, but it felt like dinner had a little secret twist. I didn’t measure my patience perfectly, so a couple of edges were extra crispy — not a disaster, just a happy accident.
Why You’ll Love It:
- Ready in under 20 minutes, which means less time cooking and more time relaxing.
- The Dijon mustard and Old Bay combo offers a tangy, savory flavor that’s a step up from plain salmon.
- Air frying gives you a crispy exterior without extra oil — healthier and fuss-free.
- It’s simple — and that’s kind of the point. No complicated prep or fancy ingredients needed.
- It’s easy to adjust timing if you prefer your salmon a bit more or less crispy (though I usually lean toward a bit extra crisp).
If you’re new to air frying fish, don’t worry. Salmon is forgiving, and this recipe is a great place to start. Just keep an eye on it the first time — air fryer models can vary a bit. You’ll get the hang of it fast, and dinner will feel like less of a chore.

Description
A quick and flavorful air fryer salmon recipe featuring a tangy Dijon mustard and Old Bay seasoning glaze. Perfectly cooked salmon with a crispy exterior and tender interior, ready in under 20 minutes.
Ingredients
2 salmon fillets, skin on, about 6 ounces each
1 tablespoon Dijon mustard
1 teaspoon Old Bay seasoning
1 teaspoon olive oil
1/2 teaspoon garlic powder
1/4 teaspoon freshly ground black pepper
1/4 teaspoon salt
Instructions
Preheat the air fryer to 400°F (200°C) for 5 minutes.
In a small bowl, mix together the Dijon mustard, Old Bay seasoning, olive oil, garlic powder, black pepper, and salt until well combined.
Pat the salmon fillets dry with paper towels.
Brush the Dijon mustard mixture evenly over the top of each salmon fillet.
Place the salmon fillets in the air fryer basket skin side down, making sure they do not overlap.
Air fry the salmon at 400°F (200°C) for 10 to 12 minutes, or until the salmon flakes easily with a fork and reaches an internal temperature of 145°F (63°C).
Carefully remove the salmon from the air fryer and serve immediately.

Kitchen Notes: You don’t need anything special beyond a standard air fryer. Just make sure the basket isn’t overcrowded so the salmon can crisp nicely. I often serve this with a simple side salad or roasted veggies — something fresh to balance the rich tang of the mustard glaze. Sometimes I swap Old Bay for smoked paprika or a pinch of cayenne if I want a little heat, though I haven’t tested those swaps thoroughly. Also, if you like your salmon a bit less crispy, shaving a minute or two off the cook time works well. Leftovers reheat nicely in the air fryer, but keep the time short or it gets drier than I like.
FAQ
Can I use frozen salmon fillets? I usually prefer fresh or fully thawed fillets for best texture, but you can try frozen if you adjust the cook time and check doneness carefully.
Is Old Bay essential? It really adds that signature flavor, but you can experiment with other spice blends if you’re out of it.
How do I know when the salmon is done? It flakes easily with a fork and reaches 145°F internally. If you don’t have a thermometer, look for opaque flesh and gentle flaking.
Can I make this without air fryer? Sure, but the crispiness might not be quite the same. Oven broiling is a decent alternative.
Give this a whirl next time you want something quick but a little different. It’s a neat way to turn simple salmon into a dinner that feels like you actually planned ahead. Save it, print it, and get ready to enjoy that crisp tangy bite.
