Can I Cook Frozen Fish in an Air Fryer? The Short Answer

You just opened your freezer and realized you forgot to thaw the fish for dinner. Panic sets in—until you remember your air fryer is sitting on the counter, ready to save the day. Can you cook frozen fish in an air fryer? Yes, absolutely! Not only is it possible, but it might be one of the easiest, most efficient ways to get dinner on the table in under 20 minutes. No thawing, no mess, no stress.

As someone who’s burned frozen fish in the oven and ended up with rubbery fillets, I was skeptical at first. But after testing dozens of batches—from breaded cod to wild-caught salmon—I’ve found that the air fryer delivers crispy exteriors, flaky centers, and minimal cleanup. It’s a game-changer for busy weeknights, last-minute guests, or anyone tired of defrosting meat in the microwave. Whether you’re a seasoned air fryer pro or just starting out, this guide will walk you through everything you need to know to cook frozen fish perfectly—every single time.

How the Air Fryer Works (and Why It’s Great for Frozen Fish)

Understanding the Magic of Hot Air Circulation

An air fryer isn’t actually a fryer—it’s a compact convection oven. A heating element warms the air, and a powerful fan circulates that hot air around the food at high speed. This creates a crispy, golden exterior without needing to submerge the food in oil. For frozen fish, this means the surface thaws and crisps simultaneously while the inside cooks evenly.

Unlike traditional ovens, which can take 15–20 minutes just to preheat, air fryers heat up in 2–3 minutes. The small cooking chamber also retains heat better, which speeds up the process. This is especially helpful when cooking from frozen, as the fish doesn’t have time to dry out or cook unevenly.

Why Frozen Fish Works So Well

Frozen fish is often flash-frozen at peak freshness, locking in moisture and flavor. When you cook it from frozen in an air fryer, the rapid circulation of hot air helps the exterior develop a crisp crust while the interior thaws and cooks through. The key is not to overcrowd the basket—each piece needs space for air to flow.

Here’s a quick tip from my own kitchen: I once tried cooking four large breaded fish fillets at once. The result? Soggy, unevenly cooked fish. After that, I learned to cook in batches. Now, I get golden, restaurant-quality fish every time. The air fryer’s design rewards patience—don’t rush it!

Common Misconceptions About Cooking Frozen Food

• “It’ll cook unevenly.” Not if you follow proper spacing and timing. The air fryer’s circulation minimizes hot spots.
• “It’ll dry out the fish.” Actually, the opposite can happen. The crust seals in moisture, especially with breaded or battered varieties.
• “It’s not safe to cook from frozen.” As long as the internal temperature reaches 145°F (63°C), it’s perfectly safe. Use a meat thermometer to check.

One of my favorite things about cooking frozen fish in the air fryer? No oil splatter, no greasy stovetop, and the basket is usually dishwasher-safe. It’s like cooking with a self-cleaning oven.

Step-by-Step Guide: How to Cook Frozen Fish in an Air Fryer

1. Prep the Air Fryer Basket

Start by lightly spraying or brushing the basket with cooking oil (avocado, olive, or canola work well). This prevents sticking and helps the fish crisp up. You can also use parchment paper liners—just make sure they don’t block airflow. I’ve found that reusable silicone liners are eco-friendly and work great.

Pro tip: If your fish has a breading or batter, a light spritz of oil on top before cooking adds extra crispiness. But don’t overdo it—too much oil can drip into the heating element and cause smoke.

2. Arrange the Fish Properly

Place the frozen fish in a single layer with at least ½ inch of space between each piece. Overlapping or stacking leads to uneven cooking. If you’re cooking fillets, place them skin-side down (if applicable) for even browning.

For smaller items like fish sticks or popcorn shrimp, toss them in the basket and shake halfway through to ensure all sides cook evenly. I once skipped the shake step and ended up with half-cooked fish sticks—lesson learned!

3. Set the Temperature and Time

Here’s a general rule of thumb:

• Breaded/battered fish (fillets, sticks): 375°F (190°C) for 12–15 minutes
• Uncoated fish (salmon, cod, tilapia): 390°F (200°C) for 10–14 minutes
• Large or thick fillets: Add 2–3 minutes

Always flip halfway through for even cooking. Use tongs or a spatula to avoid breaking delicate fillets. I use a fish spatula—it’s thin and flexible, perfect for flipping without tearing.

4. Check for Doneness

Insert a meat thermometer into the thickest part of the fish. It should read 145°F (63°C). The fish should flake easily with a fork. If it’s still icy in the center, cook in 1–2 minute increments.

For breaded fish, the coating should be golden brown and crispy. If it’s browning too quickly, reduce the temperature by 10–20°F and extend the time slightly.

5. Rest and Serve

Let the fish rest for 2–3 minutes after cooking. This allows the juices to redistribute, resulting in a more tender bite. I learned this trick from a chef friend—it makes a noticeable difference!

Serve with lemon wedges, tartar sauce, or your favorite sides. A quick squeeze of lemon brightens up the flavor, especially with mild white fish like cod or haddock.

Best Types of Frozen Fish for Air Frying

Breaded and Battered Fish (Fillets, Sticks, Popcorn Shrimp)

These are the easiest to cook from frozen. The breading crisps up beautifully, and the air fryer eliminates the need for deep frying. I’ve had great success with store-bought brands like Gorton’s, Van de Kamp’s, and Trident. For a healthier twist, look for panko-breaded or gluten-free options.

One of my favorite hacks: Sprinkle a little garlic powder or smoked paprika on top before air frying. It adds depth without extra calories.

Uncoated White Fish (Cod, Haddock, Tilapia)

These lean fillets cook quickly and stay tender when air fried. Since they don’t have a coating, you’ll want to brush them lightly with oil or spray them to prevent drying out. Season simply with salt, pepper, and lemon zest—or go bold with Cajun seasoning or lemon-herb mix.

I once tried air frying frozen tilapia with a lemon-garlic butter sauce drizzled on top. It was so good, my family asked for seconds!

Salmon Fillets

Frozen salmon can be tricky—it’s thicker and fattier than white fish. But when done right, it’s incredibly rich and flaky. Cook at 390°F (200°C) for 12–15 minutes, flipping halfway. The skin crisps up beautifully, and the flesh stays moist.

Pro tip: If the salmon is skin-on, cook skin-side down first for 7–8 minutes, then flip to finish. This ensures the skin gets crispy without overcooking the top.

Fish Cakes, Nuggets, and Specialty Items

Frozen fish cakes (like salmon or crab cakes) work well in the air fryer. Cook at 375°F (190°C) for 10–12 minutes, flipping once. They develop a golden crust while staying moist inside.

Fish nuggets and fish balls are perfect for kids (or adults!). They cook faster—usually 8–10 minutes—and stay tender. I’ve even made “fish tacos” with frozen nuggets, avocado, and salsa. Quick, easy, and crowd-pleasing.

Common Mistakes to Avoid (and How to Fix Them)

Overcrowding the Basket

This is the #1 mistake. When you pack the basket too full, hot air can’t circulate. The result? Soggy, unevenly cooked fish. I’ve been guilty of this when I’m in a hurry, but I’ve learned to slow down and cook in batches. It’s worth the extra 5 minutes.

Solution: Cook 2–3 fillets at a time (or 1 cup of fish sticks). You’ll get better results and avoid frustration.

Not Flipping the Fish

Flipping ensures even cooking and crispiness on both sides. Skipping this step can leave one side pale and soft. I use tongs to gently flip—no need to be aggressive.

For fish sticks or nuggets, shake the basket halfway through instead of flipping. It’s faster and works just as well.

Using Too Much or Too Little Oil

Too much oil can drip into the heating element and cause smoke or a burning smell. Too little oil leads to dry, tough fish.

Solution: Lightly spray or brush the fish with oil. For breaded fish, 1–2 teaspoons per fillet is plenty. For uncoated fish, ½ teaspoon per fillet.

Ignoring Thickness and Starting Temperature

A 1-inch thick salmon fillet needs more time than a thin tilapia fillet. And a fish that’s been in the freezer for weeks might be colder than one just pulled out.

Solution: Adjust cooking time based on thickness. Use a thermometer to check doneness. If the fish is still icy, add 1–2 minutes.

Not Preheating (Sometimes)

Most air fryers don’t require preheating, but preheating for 2–3 minutes can help frozen fish start cooking faster. This is especially useful for thick or large fillets.

I preheat mine when I’m cooking salmon or large cod fillets. For fish sticks, I skip it—they cook fast anyway.
