Why This Recipe Is Awesome

First of all, it’s ridiculously easy. Like, “even-I-can’t-mess-this-up” easy. You season it, air fry it, drizzle it with lemon butter, and boom dinner.

Second, it’s fast. We’re talking under 15 minutes total. That’s less time than it takes to decide what to watch on Netflix.

Third, cod is mild and flaky. If you think you don’t like fish, this recipe might change your mind. It doesn’t punch you in the face with ocean flavor. It’s gentle. Polite. Respectful.

And let’s not forget the lemon butter situation. That sauce? It’s bright, rich, and slightly dramatic in a good way. It makes the cod taste like you ordered it at a cute seaside café, not made it in pajamas.

Oh, and cleanup? Minimal. The air fryer basket handles the mess, and you move on with your life.

Ingredients You’ll Need

Here’s your short and sweet shopping list:

2 cod fillets (fresh or thawed no icy bricks, please)
1–2 tablespoons olive oil (helps it crisp up nicely)
Salt (don’t skip it, unless bland is your brand)
Black pepper (freshly cracked if you’re feeling fancy)
½ teaspoon garlic powder (because garlic = life)
½ teaspoon paprika (adds subtle warmth and color)
2 tablespoons butter (real butter. This is not the time to be shy.)
1–2 tablespoons fresh lemon juice (bright and zesty)
Lemon slices (optional, but they make it look Instagram-ready)
Fresh parsley (optional garnish for “chef energy”)

That’s it. No complicated marinades. No 27-step prep process. Just simple ingredients doing their thing.

Step-by-Step Instructions

1. Preheat the air fryer

Set your air fryer to 400°F (200°C) and let it preheat for about 3–5 minutes. Yes, preheating matters. Don’t skip it. It helps the cod cook evenly and get that slight crisp on the outside.

2. Pat the cod dry

Use paper towels to pat the fillets dry. This step is low effort but high reward. Dry fish = better seasoning and better texture. Wet fish = sad, steamy fish.

3. Season like you mean it

Brush the fillets lightly with olive oil. Sprinkle salt, pepper, garlic powder, and paprika on both sides. Don’t dump everything in one corner—spread it evenly. You want flavor in every bite.

4. Air fry

Place the cod in the basket in a single layer. No stacking. No overlapping. Give them personal space.
Air fry for 8–10 minutes, depending on thickness. The fish should flake easily with a fork and reach an internal temperature of 145°F.

5. Make the lemon butter

While the cod cooks, melt the butter in a small pan or microwave. Stir in fresh lemon juice. Taste it. Smile. Resist drinking it straight.

6. Drizzle and serve

Once the cod is done, drizzle that glorious lemon butter over the top. Add lemon slices and parsley if you want extra flair. Serve immediately and act casual about your impressive skills.

Common Mistakes to Avoid

Not drying the fish.
I know it seems unnecessary. It’s not. Moisture prevents crisping. Don’t sabotage yourself.

Overcooking it.
Cod cooks fast. Walk away for too long and you’ll end up with dry, flaky sadness. Check it at the 8-minute mark.

Overcrowding the basket.
Thinking you can squeeze in four fillets because “they’ll shrink anyway”? Rookie move. Air needs to circulate.

Skipping seasoning.
Cod is mild. That’s great—but it also means you need to season it properly. Bland fish is a crime against dinner.

Forgetting to preheat.
Yes, again. Preheat. Your future self will thank you.

Alternatives & Substitutions

No cod? No problem.

You can swap in:

Haddock – Similar texture and flavor. Works beautifully.
Tilapia – Slightly thinner, so reduce cooking time a bit.
Halibut – A bit meatier and more expensive, but wow.

Want to switch up the flavor?

Add a pinch of cayenne for heat.
Mix in Italian seasoning for a herby vibe.
Add minced garlic to the butter if you’re feeling bold.

No fresh lemon? Bottled works in a pinch. IMO, fresh tastes brighter but we’re not judging.

Trying to keep it dairy-free? Use a plant-based butter alternative. It won’t be quite as rich, but it’ll still get the job done.

FAQ (Frequently Asked Questions)

Can I use frozen cod?
Yes but thaw it first. Cooking it straight from frozen will mess with the texture and cooking time. Pat it dry after thawing, too.

How do I know when it’s done?
It should flake easily with a fork and look opaque throughout. If you have a thermometer, aim for 145°F. No guessing games needed.

Can I marinate the cod beforehand?
Sure, but keep it simple. A quick 15–20 minute marinade with lemon, olive oil, and herbs is plenty. Cod is delicate don’t drown it.

Can I use margarine instead of butter?
Technically, yes. But why hurt your soul like that? Real butter gives the best flavor.

What should I serve it with?
Roasted veggies, rice, mashed potatoes, or a crisp salad. It’s versatile. Even air-fried asparagus makes a great sidekick.

Can I store leftovers?
Absolutely. Store in an airtight container in the fridge for up to 2 days. Reheat gently in the air fryer for a few minutes so it doesn’t dry out.

Will my kitchen smell super fishy?
Nope. That’s one of the perks of the air fryer. Way less lingering fish smell compared to pan-frying.
