Air Fryer Cod Fillets with Lemon Garlic Butter
Cod is a lean, delicate white fish prized for its mild, clean flavor and large, tender flakes. Because cod has low intramuscular fat, pan-searing it often causes the delicate fillets to break apart in the pan, while oven baking can dry them out. The air fryer's rapid convection airflow cooks the fish quickly from all sides, sealing in natural moisture while gently caramelizing the seasoned surface in just 10 minutes.
Instructions
- 01
If using frozen cod, thaw completely in the refrigerator overnight. Place the cod fillets on a cutting board lined with paper towels and pat them completely dry on both sides.
- 02
In a small ramekin, combine the smoked paprika, garlic powder, kosher salt, and black pepper.
- 03
Brush the cod fillets on all sides with 1 tablespoon of olive oil, then sprinkle the seasoning rub evenly over top and sides.
- 04
Preheat your air fryer to 375°F (190°C) for 3 minutes. Lightly grease the air fryer basket with olive oil spray or a light brush of oil.
- 05
Carefully place the seasoned cod fillets in a single layer in the air fryer basket with space between each piece.
- 06
Air fry at 375°F (190°C) for 9 to 11 minutes (9 to 10 minutes for 3/4-inch fillets; 11 to 12 minutes for thick center-cut loins). Do not flip the fish, as delicate cod can break apart.
- 07
Confirm food-safety doneness with a digital meat thermometer inserted into the thickest part of the fillet (target 145°F / 63°C, or until the flesh turns completely opaque and flakes easily when pressed with a fork).
- 08
While the cod cooks, stir together the melted butter, minced garlic, fresh lemon juice, and chopped parsley in a small bowl.
- 09
Carefully transfer the cooked fillets to plates using a wide fish spatula. Spoon the warm lemon garlic butter over the hot fillets, garnish with fresh parsley and lemon wedges, and serve immediately.
- ✦Thickness Governs Timing: Standard 3/4-inch cod fillets take 9 to 10 minutes; thick 1.25-inch center-cut cod loins require 11 to 13 minutes. Check internal temperature at the 9-minute mark.
- ✦Do Not Flip the Cod: Cod is delicate and tender. Flipping risks breaking the fillet apart. The rapid 360-degree convection airflow cooks both sides evenly without flipping.
- ✦Internal Temperature Rule: While flakiness is a traditional visual test, use a digital thermometer to confirm an internal temperature of 145°F (63°C) for food safety.
- ✦Thoroughly Dry the Fish: Patting the fish dry with paper towels prevents excess liquid from pooling in the basket, ensuring the fish roasts instead of boiling.
- ✦Other White Fish Swaps: This exact recipe and timing work identically for haddock, halibut, sea bass, or tilapia fillets.

Frequently Asked Questions
Q: How long does cod take in the air fryer?
A: Fresh or thawed cod fillets cook in 9 to 11 minutes at 375°F (190°C) without flipping, until the internal temperature reaches 145°F and the flesh flakes easily.
Q: Do you need to flip cod in the air fryer?
A: No, do not flip cod. Cod is a delicate fish and flipping can cause it to break. The circulating convection airflow cooks the fillet completely through from all angles.
Q: Can I cook frozen cod in the air fryer without thawing?
A: Yes, you can cook frozen cod using a two-stage method: air fry at 360°F for 6 minutes to thaw, brush with oil and spices, and finish at 390°F for 7 to 9 minutes until it reaches 145°F.
Q: How do you know when air fryer cod is cooked?
A: Cod is done when an instant-read digital thermometer reads 145°F (63°C) in the thickest center, the flesh turns opaque white, and flakes effortlessly with a fork.
Q: How do you reheat leftover cod in an air fryer?
A: Reheat leftover cod gently in the air fryer at 320°F (160°C) for 3 to 4 minutes until just heated through to avoid drying out the delicate fish.
