How To Air Fry Frozen Fish Fillets In Air Fryer
This is the core method for most types of frozen breaded or battered fish fillets. Brands like Gorton’s, Van de Kamp’s, or store-brand options all work well. The key is to not thaw them first. Cooking from frozen ensures the coating gets crispy while the inside heats through properly.
What You’ll Need
- Frozen fish fillets (breaded, battered, or plain)
- Air fryer
- Cooking oil spray (like avocado or canola oil)
- Tongs or a spatula
- Instant-read thermometer (optional but helpful)
Step-by-Step Instructions
1. Preheat Your Air Fryer
Start by preheating your air fryer to 400°F (200°C). This usually takes about 3-5 minutes. Preheating is crucial for getting that immediate crispiness when the cold fish hits the basket. It helps the cooking process start right away.
2. Arrange the Fillets in the Basket
Take your frozen fillets and place them in the air fryer basket in a single layer. Do not overcrowd them. They need space for the hot air to circulate all around. If they are touching, they will steam instead of getting crispy. You may need to cook in batches.
3. Lightly Spray with Oil
Give the tops of the frozen fillets a light spray with cooking oil. This step enhances browning and helps achieve a golden, crunchy texture. You don’t need a lot—just a quick spritz. If your fillets are already very oily, you can skip this.
4. Cook the First Side
Air fry at 400°F for 7-8 minutes. The exact time can vary a bit based on the thickness of the fillets and your specific air fryer model. Don’t shake the basket during this initial cook. Let the coating set and start to crisp.
5. Flip and Continue Cooking
Carefully flip each fillet using tongs. Spray the second side lightly with oil if it looks dry. Then, air fry for another 5-7 minutes. The total cook time is typically between 12 and 15 minutes. The outside should be deep golden brown and very crispy.
6. Check for Doneness
The best way to check is with an instant-read thermometer. Insert it into the thickest part of the fillet; it should read at least 145°F (63°C). If you don’t have a thermometer, the fish should be opaque all the way through and flake easily with a fork.
7. Serve Immediately
Take the fillets out of the basket and serve them right away. They are at their crispiest when they’re fresh from the air fryer. They pair great with fries, coleslaw, tartar sauce, or a simple squeeze of lemon.
Tips for the Best Results
- Always check your air fryer’s manual for specific recommendations.
- Shake the basket gently when flipping, don’t just toss them around.
- For extra crispiness, you can add a minute or two at the end.
- Let the fillets sit for a minute before cutting into them, this helps the coating stay intact.
Adjustments for Different Types of Fish
Not all frozen fish is the same. Here’s how to adjust for different varieties.
Breaded or Battered Fillets (Like Fish Sticks or Beer-Battered)
These are the most common. Follow the standard method above. The breading creates a protective layer that keeps the fish moist. Be sure not to overlap them, as the batter can stick together.
Unbreaded, Plain Frozen Fillets (Like Salmon, Cod, or Tilapia)
For plain frozen fish, you need a different approach. Brush or spray the fillets with a bit more oil. Season them generously with salt, pepper, and your favorite herbs (like dill or paprika) before cooking. You might need to reduce the temperature to 380°F to prevent the outside from drying before the inside is done. Cook for 10-14 minutes total, flipping halfway.
Thick Frozen Fillets (Like Salmon or Halibut Steaks)
Thicker cuts require a lower temperature and longer time. Try 375°F. Cook for 10 minutes, then flip and cook for another 8-10 minutes. Always use a thermometer to ensure the center is hot. Letting them rest for 2-3 minutes after cooking helps the heat distribute evenly.
Frozen Fish Burgers or Patties
These are often denser. Cook them at 380°F for about 12-15 minutes, flipping halfway through. Make sure the internal temperature reaches 145°F. You can toast the buns in the air fryer for the last minute of cooking.
Common Mistakes to Avoid
Even simple methods have pitfalls. Here’s what to watch out for.
- Overcrowding the Basket: This is the number one cause of soggy fish. Air needs to flow. Cook in batches if you have to.
- Skipping the Preheat: Putting frozen food into a cold air fryer leads to uneven cooking and a less crispy texture.
- Not Flipping: Flipping is essential for even browning and cooking on all sides. Don’t forget this step.
- Using Parchment Paper with Holes: While parchment liners can be helpful, they can also block air flow from the bottom. If you use one, make sure it’s perforated or cut to fit well, and consider spraying it with oil so the fish doesn’t stick.
- Ignoring Your Model’s Quirks: Some air fryers run hotter than others. Get to know yours. It might require slight time or temp adjustments.
Seasoning and Flavor Ideas
You can easily customize your frozen fish. Add these seasonings after the first flip, so they don’t burn.
- Lemon Pepper: A classic. Spray with oil, then sprinkle generously with lemon pepper seasoning.
- Cajun Spice: For a bit of heat, use a Cajun or blackening spice blend.
- Garlic & Herb: Sprinkle with garlic powder, dried parsley, and a little onion powder.
- Simple Lemon: Just serve with fresh lemon wedges. The bright acid cuts through the richness perfectly.
Serving Suggestions
What to serve with your air fried fish? Plenty of easy options.
- Classic Sides: Air fryer french fries, sweet potato fries, or onion rings. You can cook these right after the fish, or in a second basket if you have a dual-zone model.
- Lighter Sides: A simple green salad, steamed vegetables, or a tangy coleslaw.
- Sauces: Tartar sauce, remoulade, cocktail sauce, or a quick dill yogurt sauce.
- For a Meal: Make fish tacos with cabbage slaw and a creamy sauce, or put the fillet on a bun for a sandwich.
Cleaning Your Air Fryer Afterwards
Fish can leave a odor. Here’s how to clean up fast.
- Unplug the appliance and let it cool completely.
- Remove the basket and pan. Wash them in warm, soapy water. Most are dishwasher safe.
- Wipe the inside of the air fryer with a damp cloth. Never submerge the main unit.
- For lingering smells, place a slice of lemon or a bowl of baking soda in the dry basket and run it at 350°F for 5 minutes.
FAQ Section
Do I need to thaw frozen fish before air frying?
No, you should not thaw it. Cooking frozen fish fillets directly in the air fryer gives the best results. Thawing can make the coating soggy and lead to overcooked fish.
What temperature is best for air frying frozen fish?
400°F (200°C) is the ideal temperature for most breaded frozen fish. For plain or very thick fillets, you might reduce it to 375°F to ensure the inside cooks through without burning the outside.
How long does it take to air fry frozen fish fillets?
It typically takes 12 to 15 minutes total. Cook for 7-8 minutes, flip, then cook for another 5-7 minutes. Always check for an internal temperature of 145°F.
Can I cook multiple frozen fish fillets at once?
Yes, but they must be in a single layer without touching. If your basket is small, cook in batches. Overcrowding will give you steamed, soft fish instead of crispy fish.
Why is my air fried fish not crispy?
The most common reasons are overcrowding the basket, not preheating the air fryer, or not using a little oil spray. Also, ensure you are cooking at a high enough temperature (400°F).
Can I use aluminum foil in the air fryer with fish?
You can, but use it sparingly. A small piece under the fish can help with cleanup, but don’t let it cover the entire basket as it will severely restrict air flow. Always secure the foil so it doesn’t get blown around by the fan.
Troubleshooting Guide
If things didn’t go as planned, here’s how to fix it next time.
- Soggy Bottom: This happens from overcrowding or using a solid liner. Give each piece space and ensure air can get underneath.
- Coating Falling Off: You might be handling them to roughly. Use a gentle touch with your tongs when flipping. Also, a light spray of oil can help the coating adhere as it cooks.
- Undercooked Center: Your fillets might be thicker than you thought. If the outside is done but the inside is cold, lower the temperature to 370°F and cook for a few more minutes. A thermometer is your best friend here.
- Burnt Edges: Your air fryer might have hot spots. Try rotating the basket (not just flipping the food) halfway through cooking. You can also lower the temperature by 25 degrees next time.
Mastering how to air fry frozen fish fillets in air fryer is all about following a few simple rules. Remember the key steps: preheat, don’t overcrowd, flip halfway, and always check for doneness. With this method, you have a reliable way to prepare a fast, tasty, and healthier fish dinner any night of the week. Experiment with different seasonings and sides to keep it interesting. The air fryer makes it so simple, you’ll find yourself using this technique again and again.
