Crispy Frozen Battered Fish in the Air Fryer – Quick, Mess-Free & Delicious
When I’m craving a flaky piece of battered fish without deep frying or greasy cleanup, I always prefer to go for the air fryer.
It’s hands-down the easiest way to get a crispy finish while keeping the inside juicy and tender. No thawing, no oil splatter — just pop the frozen fish in and let the air fryer work its magic.
I suggest using a basket-style air fryer set at 390°F for frozen battered fish fillets. The batter crisps up beautifully while the fish inside stays moist.
I prefer not to add oil spray, as most battered fish already has oil in the coating. Just flip once halfway through for even browning, and they’re done in about 12–14 minutes.
Serve with lemon, tartar sauce, or even a side of chips for a classic feel.

How Long to Cook Frozen Battered Fish in Air Fryer?
Time varies depending on air fryer style, fish thickness, and coating type. Here’s a breakdown:
- Basket-style air fryer:
- Standard fillets: 390°F for 12–14 minutes
- Thicker fillets: 400°F for 14–16 minutes
- Fish fingers: 380°F for 8–10 minutes
- Oven-style air fryer:
- 400°F for 15–17 minutes; rotate trays halfway
- Compact air fryer:
- Reduce to 375°F and monitor closely after 10 minutes
- Flip gently to prevent batter sticking
Tips based on batter/coating:
- Thicker batter may take longer to crisp up
- Pre-oiled fish may brown faster — no need for extra spray
- Always flip halfway for even texture and golden crust
How to Make Frozen Battered Fish in Air Fryer – Step-by-Step
For this recipe, I recommend using a basket-style air fryer preheated to 390°F.
Step 1: Preheat the Air Fryer
Preheat at 390°F for about 3 minutes. A hot basket ensures the fish starts crisping immediately.
Step 2: Arrange the Fish
Place frozen fish fillets in the basket — keep space between pieces. Don’t stack or overlap.
Step 3: No Need for Oil
Most battered fish already contains oil. Adding spray may make them greasy or soggy.
Step 4: Cook and Flip
Air fry for 6–7 minutes. Then flip each piece gently with a spatula and cook for another 6–7 minutes or until golden brown and crispy on all sides.
Step 5: Cool Briefly
Let them sit for 2 minutes. This allows the coating to firm up and the steam to settle inside.
Serving & Decoration Tips
- Serve with lemon wedges, tartar sauce, or halal garlic mayo
- Pair with air-fried potato wedges or coleslaw
- Add chopped parsley or dill for a fresh, vibrant finish
- A slice of toasted bread or wrap turns this into a quick sandwich
Variations to Try
- Fish Tacos: Flake the fish and serve in soft tortillas with slaw and creamy sauce
- Spicy Twist: Sprinkle chili powder or paprika before serving
- Fish & Chips Night: Add frozen fries in a second basket — cook both side-by-side
- Mini Fish Sliders: Use smaller fillets in buns with lettuce and sauce
Storing Tips
- ✅ Store cooled leftovers in an airtight container in the fridge up to 2 days
- ✅ Reheat in the air fryer at 370°F for 4–5 minutes
- ✅ Use a paper towel underneath to absorb excess moisture
- ❌ Don’t microwave — it ruins the crisp coating
- ✅ Avoid freezing after cooking — the batter gets soft when reheated from frozen
Extra Tips for Best Air Fryer Results
- ✅ Preheat every time for a crispy shell
- ✅ Don’t overcrowd — give each piece space
- ✅ Flip gently to avoid tearing the coating
- ✅ Use parchment with holes if sticking is a problem
- ✅ Serve immediately after cooking for best texture
Common Mistakes, Solutions & Prevention
| Mistake | Cause | Solution | Prevention |
|---|---|---|---|
| Coating sticks to basket | No parchment or flipping too early | Use parchment with holes or wait before flipping | Flip halfway only once |
| Undercooked center | Too thick or too short cooking time | Increase cook time by 2–3 mins | Use thermometer if unsure (145°F inside) |
| Soggy batter | Overcrowding or no preheat | Cook fewer pieces and preheat | Don’t layer or stack |
Air Fryer Tips for Frozen Battered Fish
- Use a silicone liner or parchment with holes for easy cleanup
- Thinner fish cooks faster — keep an eye around the 10-minute mark
- If cooking more than one batch, subsequent batches may cook quicker
- Keep a digital meat thermometer handy if unsure about doneness
Helpful FAQs
Q1: Can I cook battered fish and fries together in one air fryer?
A1: Yes, if your air fryer is large enough. Use a divider or cook fries in a second round to avoid crowding.
Q2: Should I defrost the fish before air frying?
A2: No — it’s designed to be cooked from frozen. Thawing makes the coating soggy.
Q3: How do I keep the batter from flaking off?
A3: Flip gently only once, and avoid stacking or pressing the fish. Also, don’t use tongs with too much pressure.
Q4: Can I add seasoning before cooking?
A4: Avoid adding spices before cooking; they may burn. Add them lightly after cooking instead.
