Instructions
Step 1: Prep the Fish
Pat 6 cod fillets dry with paper towels. Lightly dust them with 1/2 cup flour, a pinch of salt, and a pinch of black pepper on both sides.
Step 2: Start Air Frying
Place the coated cod fillets into the air fryer basket (lined with a baking sheet if needed). Cook on roast setting at 400°F for 6 minutes.
Step 3: Make Lemon Garlic Butter
In a bowl, mix 75g melted butter, 5–6 cloves finely grated garlic, 1 tsp salt, 1/2 tsp black pepper, 1 tsp dried parsley, 1 tsp smoked paprika, and 3 tbsp fresh lemon juice.
Step 4: Flip and Add Sauce
After 6 minutes, flip the cod fillets. Pour the lemon garlic butter mixture evenly over each piece.
Step 5: Finish Cooking
Air fry for another 3 minutes until the fish is flaky and fully cooked, then serve with your favorite sides like steamed broccoli, cauliflower rice, garlic green beans, or a simple side salad. Spoon any extra sauce over the top for even more flavor.
Pro Tips
- Pat the fish really dry—this helps the coating stick better
- Don’t skip flipping—it helps cook evenly and soak in the sauce
- Use fresh lemon juice for the best flavor
- Don’t overcrowd the air fryer—cook in batches if needed
- Spoon extra sauce over the fish before serving
Substitutions and Variations
- Swap cod for tilapia, haddock, or halibut
- Use ghee instead of butter for a deeper flavor
- Add chili flakes for a spicy kick
- Try fresh parsley instead of dried for a brighter taste
Make Ahead Tips
You can mix the lemon garlic butter ahead of time and store it in the fridge for up to 2 days. Just re-melt before using.

Why This Recipe Works (Quick Science)
The flour creates a light coating that helps the butter sauce stick to the fish. The air fryer uses hot circulating air to cook the cod quickly while keeping it moist inside. The butter carries fat-soluble flavors from garlic and spices, spreading them evenly across the fish.
Common Mistakes
- Not drying the fish (leads to soggy texture)
- Adding sauce too early (can make coating fall off)
- Overcooking (fish becomes dry fast)
- Using bottled lemon juice (flavor won’t be as fresh)
What to Serve With
- Steamed broccoli
- Cauliflower rice
- Garlic green beans
- Simple side salad
- Zucchini noodles
FAQ
Can I use frozen cod?
Yes, just thaw it completely and pat dry before using.
Do I need to preheat the air fryer?
It helps, but it’s not required. Just add 1–2 extra minutes if not preheated.
How do I know it’s done?
The fish should flake easily with a fork and look opaque.
Can I bake this instead?
Yes, bake at 400°F for about 12–15 minutes.
Leftovers and Storage
Store leftovers in an airtight container in the fridge for up to 2 days. Reheat in the air fryer for 2–3 minutes to keep it crispy. Avoid microwaving if possible—it softens the texture.
