Frozen Salmon in Air Fryer (No Thaw Recipe Ready in 20 Minutes)

This air fryer salmon recipe is hands-down one of the easiest and fastest ways to cook frozen salmon—no thawing required. The salmon cooks straight from frozen in under 20 minutes, and my method is foolproof. It turns out perfectly flaky and tender with crisp edges and a delicious flavor from the dijon-lemon glaze that caramelizes in the air fryer. I’ve created countless salmon recipes over the years—like my miso salmon and bourbon salmon—and those never disappoint, so you know this frozen salmon recipe will deliver. 

Why I Love This Frozen Salmon Recipe

I love this recipe because it takes the stress out of cooking salmon. You don’t have to plan ahead or wait for frozen fillets to thaw—it goes straight from the freezer to the air fryer and cooks perfectly every time. The Dijon, lemon, and olive oil glaze adds the right balance of tangy, savory, and fresh flavors, while the air fryer seals in moisture and gives the salmon crisp, golden edges that I've found hard to achieve in other salmon recipes.

This is one of my favorite dinners to make on busy nights when I want something quick but still healthy and satisfying. I usually pair it with a side of roasted frozen broccoli and French fries or rice for a complete meal that's balanced but effortless. Once you try it, you’ll see why this frozen air fryer salmon is just as good as any fresh salmon recipe—and maybe even better.

My Expert Tips To Make The Best Frozen Salmon Recipe

• No need to thaw—cook straight from frozen: That’s the beauty of this recipe! The air fryer’s circulating hot air cooks the salmon evenly from frozen, keeping the center tender and flaky while crisping up the edges. No defrosting, no waiting—just delicious results every time.
• Pat off any ice crystals before seasoning: If your frozen fillets have visible ice on the surface, gently pat them dry with paper towels. This small step prevents the salmon from steaming in the air fryer and helps the Dijon glaze stick better for more flavor and color.
• Use a meat thermometer for accuracy: Air fryer times can vary depending on the thickness of your fillets, but most frozen salmon cooks perfectly in 12–18 minutes at 390°F. For restaurant-quality results, check for an internal temperature of 145°F in the thickest part of the fillet.
• Brush with extra glaze halfway through: For thicker fillets, pause the air fryer around the halfway point and brush on another layer of the Dijon-lemon glaze. This builds flavor and creates a light, caramelized crust that makes the salmon taste even more flavorful.
• Don’t overcrowd the air fryer basket: Give each piece of salmon space so the hot air can circulate freely. If you’re cooking more than two fillets, work in batches to ensure even cooking and that perfect flaky texture.
• Finish with acid and herbs: Right before serving, squeeze fresh lemon juice over the salmon and sprinkle with chopped parsley or dill. That hit of acid brightens the glaze and adds a pop of freshness that balances the richness of the fish.
• Great for meal prep: This air fryer salmon reheats well, making it ideal for quick lunches or easy dinners later in the week. Store leftovers in an airtight container in the fridge for up to 3 days, and reheat in the air fryer at 350°F for 3–4 minutes to bring back that just-cooked texture without drying it out.

Frozen Salmon Variations To Try

• Garlic Butter Salmon: For a rich, savory twist, replace the Dijon mustard with 1 tablespoon melted butter and add 1 teaspoon minced garlic to the glaze. The butter gives the salmon a silky finish, while the garlic adds depth and that irresistible aroma as it cooks.
• Spicy Salmon: If you like a little heat, stir ¼ teaspoon cayenne pepper or ½ teaspoon red pepper flakes into the glaze before brushing it over the salmon. The spice cuts through the richness and gives the dish a bold, flavorful kick.
• Maple Dijon Salmon: Swap the lemon juice for 1 tablespoon pure maple syrup for a sweet-and-savory glaze. The maple caramelizes in the air fryer, pairing well with the tangy Dijon and flaky salmon. This version is especially good with roasted sweet potatoes or rice.
• Herb-Crusted Salmon: Before cooking, sprinkle the fillets with ½ teaspoon dried dill, Italian seasoning, or a mix of thyme and parsley. The herbs infuse the salmon as it cooks, adding a layer of freshness that complements the buttery texture and mild flavor of the fish.
• Asian-Inspired Salmon: For an umami-forward twist, mix 1 tablespoon soy sauce, 1 teaspoon sesame oil, and ½ teaspoon honey into your glaze. Garnish with sesame seeds and green onions for a flavorful, Asian restaurant-style meal that’s ready in minutes.

Frozen Air Fryer Salmon FAQs

Do I need to thaw salmon before air frying?

No! This recipe is designed specifically for frozen salmon. The air fryer’s circulating heat cooks the fillets evenly from frozen, keeping them tender, juicy, and perfectly flaky. Skipping the thawing step not only saves time but also prevents the salmon from drying out.

Can I air fry salmon with the skin on?

Yes, you can. Place the fillets skin-side down in the air fryer basket. The skin crisps up beautifully during cooking, helping to protect the salmon from overcooking. You can eat the crispy skin for added texture or peel it off easily after cooking.

How long do I cook frozen salmon in the air fryer?

Frozen salmon fillets typically cook in 12–18 minutes at 390°F, depending on their thickness. Thinner fillets will be ready closer to the 12-minute mark, while thicker pieces may need the full 18 minutes. Always check for an internal temperature of 145°F in the thickest part to ensure it’s fully cooked and perfectly moist.

What sides go well with salmon?

This frozen air fryer salmon pairs with a variety of sides. Try it with Mediterranean bean salad, Cajun mashed potatoes, or rosemary garlic bread. For something lighter, serve it with a fresh green salad or  roasted brussel sprouts.

Can I make this salmon recipe ahead of time?

Yes! You can cook the salmon in advance, let it cool completely, and store it in an airtight container in the fridge for up to 3 days. To reheat, warm it in the air fryer at 350°F for 3–4 minutes until heated through. It’s also delicious served cold over salads or grain bowls for an easy, protein-packed lunch.

Can I use other sauces or glazes?

Absolutely. This recipe works as a blank canvas for different flavors. Try teriyaki glaze, McDonald's gold sauce, honey garlic sauce, or a spicy Cajun rub for variety. Just brush or drizzle your sauce during the last few minutes of cooking to keep it from burning.

Is air fryer salmon healthy?

Yes! Salmon is rich in omega-3 fatty acids, protein, and essential nutrients, and the air fryer method uses minimal oil. It’s one of the easiest and healthiest ways to cook salmon at home.
