Can Frozen Fish Be Cooked in an Air Fryer? A Quick Guide

Imagine this: it’s 5:30 p.m., you’re tired after a long day, and you open the freezer hoping for a miracle. There, nestled between last week’s frozen veggies and a forgotten bag of peas, are a few fillets of frozen fish. No thawing, no prep time—just pure, frozen convenience. But can you really cook that frozen fish straight in your air fryer? The short answer: yes, absolutely. And the best part? It can taste just as good—or even better—than if you’d thawed it first.

I’ve been there. More than once. Whether it’s a last-minute dinner decision or a “I forgot to take something out of the freezer” moment, I’ve thrown frozen fish into my air fryer with mixed results. Sometimes it came out perfectly crispy on the outside and tender inside. Other times? Dry, uneven, or stuck to the basket. Through trial, error, and a few kitchen experiments, I’ve learned that cooking frozen fish in an air fryer isn’t just possible—it’s actually one of the best ways to get a quick, healthy, and delicious meal. In this guide, I’ll walk you through everything you need to know, from the science behind it to practical tips, timing, and even which types of frozen fish work best.

Why the Air Fryer Is a Game-Changer for Frozen Fish

Let’s start with why the air fryer is such a standout tool for cooking frozen fish. Unlike ovens, which take 10–15 minutes just to preheat, or stovetops, which require constant attention, the air fryer delivers fast, even heat with minimal effort. It’s essentially a mini convection oven that circulates hot air around food at high speed, creating a crispy exterior without needing to submerge the food in oil.

How Air Frying Works for Frozen Foods

When you cook frozen fish in an air fryer, the intense, circulating heat quickly penetrates the outer layer of ice, evaporating surface moisture. This is key—because moisture is the enemy of crispiness. The air fryer’s design prevents steam buildup (which happens in microwaves or ovens with poor airflow), so the fish doesn’t end up soggy. Instead, it gets a golden, slightly crunchy crust—especially if it’s breaded or coated.

Think of it like this: the air fryer acts like a turbocharged version of pan-frying, minus the oil splatter and mess. And because frozen fish goes in cold, the gradual warming helps the center thaw and cook evenly, reducing the risk of overcooking the outside while the inside is still icy.

Health and Convenience Benefits

One of the biggest perks of air frying frozen fish is the health angle. You can achieve a crispy, restaurant-style texture using just a light spray of oil—sometimes even none at all. Compare that to deep-frying, which can add hundreds of calories and grams of fat. Air frying typically uses 80–90% less oil, making it a heart-healthier choice, especially if you’re watching sodium or cholesterol.

Plus, there’s the convenience factor. No need to plan ahead. No need to remember to thaw. Just grab, season, and go. For busy families, meal preppers, or anyone trying to eat more seafood without the hassle, this is a total win.

Personal tip: I keep a variety of frozen fish in my freezer—tilapia, salmon, cod, and even breaded fish sticks—for those “what’s for dinner?” moments. Knowing I can air fry them in 10–15 minutes with zero prep is a lifesaver.

Which Types of Frozen Fish Work Best in the Air Fryer?

Not all frozen fish are created equal when it comes to air frying. Some handle the heat better, while others can become dry or fall apart. Here’s a breakdown of the most common types and how they perform.

Lean White Fish (Cod, Tilapia, Haddock, Flounder)

These are the stars of the air fryer. Lean, mild, and relatively firm, they hold their shape well and cook evenly from frozen. Cod and tilapia are especially popular because they’re widely available, affordable, and kid-friendly.

• Best for: Breaded or seasoned fillets, fish tacos, fish sandwiches
• Texture after air frying: Flaky, tender, with a light crust (if breaded)
• Pro tip: Lightly spray with oil to enhance browning—especially for unbreaded fillets.

Fatty Fish (Salmon, Mackerel, Trout)

Salmon is a bit trickier because of its higher fat content. While it’s delicious, it can release oils as it cooks, which may cause smoking or uneven cooking if the basket isn’t well-ventilated. That said, with the right technique, frozen salmon turns out beautifully in the air fryer.

• Best for: Lemon-garlic salmon, teriyaki-glazed fillets, or simple seasoned with salt and pepper
• Texture after air frying: Moist, rich, and slightly flaky—especially if not overcooked
• Pro tip: Pat the surface dry before air frying to reduce smoke. Use a lower temperature (350°F) and check early to avoid drying out.

Breaded or Coated Frozen Fish (Fish Sticks, Fish Fillets, Fish Nuggets)

These are the easiest to cook from frozen. The breading or coating acts like armor, protecting the fish from drying out and creating that satisfying crunch we all love. Brands like Gorton’s, Birds Eye, and Van de Kamp’s work great in the air fryer.

• Best for: Quick snacks, kid-friendly meals, fish and chips at home
• Texture after air frying: Crispy on the outside, moist inside—often better than oven-baked versions
• Pro tip: Don’t overcrowd the basket. Space the pieces so hot air can circulate. Flip halfway for even browning.

Frozen Fish Cakes, Patties, and Seafood Mixes

These can be hit or miss. Fish cakes (like salmon or crab cakes) often contain fillers (breadcrumbs, eggs, veggies) that help them hold together, but they can dry out if overcooked. Seafood mixes (shrimp and fish combos) may cook unevenly due to size differences.

• Best for: Fish burgers, appetizers, or adding to pasta
• Texture after air frying: Can be moist if cooked gently, but risk of drying out is higher
• Pro tip: Cook at a lower temperature (325–350°F) and check frequently. Brush with a little oil or sauce to keep them moist.

What to Avoid

While most frozen fish work, there are a few to be cautious about:

• Very thin fillets: Can cook too fast and dry out
• Fish with heavy marinades or sauces: May drip and smoke in the basket
• Fish with large ice crystals or freezer burn: Indicates poor freezing—skip these

My experience: I once tried air frying a thin, frozen sole fillet. It cooked in 6 minutes and was delicious—but only because I monitored it closely. Thin fish needs attention.

Step-by-Step Guide to Cooking Frozen Fish in the Air Fryer

Ready to cook? Here’s a foolproof method that works for most frozen fish fillets and products. I’ve tested this across multiple air fryer models (Ninja, Cosori, Instant Vortex) and found consistent results.

Step 1: Preheat the Air Fryer (Optional but Recommended)

Most air fryers don’t need preheating, but doing so (3–5 minutes at 375°F) helps ensure even cooking from the start. It’s especially useful for thicker fillets or breaded items.

Why it helps: A hot basket means faster evaporation of surface moisture, leading to better browning and less sticking.

Step 2: Prepare the Fish

• If unbreaded, lightly spray or brush with oil (avocado, olive, or canola work well)
• Season with salt, pepper, garlic powder, lemon pepper, or your favorite spice blend
• For breaded fish, no oil is usually needed—but a light spray can enhance crispiness
• Arrange in a single layer—no overlapping

Pro tip: If you’re cooking salmon, sprinkle a little brown sugar or maple syrup for a sweet crust. It caramelizes beautifully in the air fryer.

Step 3: Set the Temperature and Time

Here’s a general guide (adjust based on thickness and brand):

• Breaded fish (sticks, nuggets, fillets): 375°F for 8–12 minutes
• Unbreaded white fish (cod, tilapia): 380°F for 10–14 minutes
• Salmon fillets: 350°F for 12–15 minutes
• Fish cakes or patties: 325°F for 10–12 minutes

Remember: These are starting points. Always check for doneness.

Step 4: Flip and Check (Optional but Helpful)

After about half the cooking time, open the basket and flip the fish. This ensures even browning and prevents sticking. Use tongs or a silicone spatula to avoid damaging non-stick coatings.

Note: Some air fryers have a “shake” reminder—great for nuggets or small pieces.

Step 5: Check for Doneness

The best way to know if fish is done? Use a meat thermometer. The internal temperature should reach 145°F. If you don’t have one, gently flake the thickest part with a fork. It should separate easily and look opaque—not translucent or icy.

Caution: Overcooked fish turns dry and tough. When in doubt, undercook slightly—you can always add 1–2 more minutes.

Step 6: Rest and Serve

Let the fish rest for 1–2 minutes after cooking. This helps the juices redistribute, keeping it moist. Then serve with lemon wedges, tartar sauce, or a fresh salad.

Common Mistakes and How to Avoid Them

Even with the best intentions, things can go wrong. Here are the most common air frying mistakes—and how to fix them.

1. Overcrowding the Basket

This is the #1 culprit for soggy, unevenly cooked fish. When fish is stacked or touching, hot air can’t circulate, and steam builds up.

Solution: Cook in batches if needed. Leave at least 1/4 inch between pieces. For large fillets, cut them in half to fit.

2. Not Using Oil (or Using Too Much)

Too little oil = pale, dry fish. Too much = greasy, smoky mess.

Solution: For unbreaded fish, use a light spray (about 1/2 tsp per fillet). For breaded fish, you can skip oil—or use a light mist for extra crisp.

3. Cooking at the Wrong Temperature

Too high, and the outside burns before the inside thaws. Too low, and it steams instead of fries.

Solution: Start with 350–375°F for most fish. Adjust based on thickness. Thin fillets? Lower and slower. Thick salmon? Slightly higher.

4. Skipping the Flip

While not always required, flipping helps with even browning—especially for breaded or skin-on fish.

Solution: Set a timer for halfway through and flip gently. Use non-metal tools to protect the basket.

5. Ignoring the Brand’s Instructions

Pre-packaged frozen fish (like fish sticks) often have recommended cooking times for air fryers on the box. These are based on real testing and are usually spot-on.

Solution: Check the packaging first. Use it as a guide, then adjust based on your air fryer’s performance.

6. Not Cleaning the Basket

Fish residue and oil buildup can smoke or affect taste over time.

Solution: Clean the basket after every use with warm, soapy water. For stubborn residue, soak in vinegar water.
