If you are looking for a simple, flavorful weeknight dinner, this Air Fryer Haddock with Lemon Chive Butter Sauce might just become a new favorite. Tender, perfectly seasoned haddock fillets cook in minutes in the air fryer. Served with a buttery lemon chive sauce made with ingredients you probably already have on hand. Serve it over wide egg noodles, fluffy mashed potatoes, or steamed rice and dinner is on the table in under 30 minutes.
I've made firmer fish like Teriyaki Salmon, Mahi Mahi and Tuna Steak in the air fryer with great results. But haddock is a softer, more delicate fish and one I would normally reach for my cast iron skillet to cook or to grill it like in my Grilled Haddock recipe. So this was genuinely an experiment. I wasn't sure how it would hold up in the air fryer, and I'm happy to report it held up beautifully.
What I didn't expect was the sauce to completely steal the show. The Lemon Chive Butter Sauce is made while the fish cooked and was so good drizzled over both the haddock and the egg noodles alongside it. You'll love this quick sauce and like most homemade sauces, you can tweak the flavor and you'll want to put it on everything.

Ingredient Notes & Substitutions
- Haddock- Fresh is always the first choice but frozen works perfectly well here. I used individually frozen fillets that I defrosted overnight in the refrigerator. Atlantic haddock is mild, slightly sweet and holds up well to seasoning. If haddock isn't available, cod is an excellent substitute with a similar mild flavor and slightly firmer texture. Pollock also works well and both are typically a bit less expensive than haddock.
- Old Bay Seasoning- This is my first choice for fish and gives it a classic, slightly spiced flavor. If you don't have Old Bay, 1 teaspoon of Italian seasoning and some paprika work as a substitute.
- Fresh Chives- Fresh chives are one of those fresh herbs that give a sauce a clean, mild onion flavor without overpowering it. They go together with the lemon and butter really well. If fresh chives aren't available, 2-3 teaspoons of dried chives are a perfectly fine substitute.
- Fresh Lemon-I really do recommend fresh rather than bottled lemon juice. It adds a citrusy flavor without being too bitter that you just can't get from bottled juice.
How to Air Fry Haddock
Step 1. Preheat air fryer to 375°F for at least 5 minutes. Spray basket lightly with non-stick cooking spray. Combine the seasonings. Pat fish very dry, rub oil on haddock and press seasonings onto both sides of fish.
Step 2: Place the fillets in a single layer; cook in two batches if needed. Don't move the fillets for the first 5-6 minutes of cooking. No flipping needed. Cook for 10-12 minutes or until the fish reaches 145°F with an internal meat thermometer and flakes easily with a fork.
Step 3: Make the sauce. Melt butter. Finely chop the scallions or use a mini food processor. Process or stir together the butter, garlic, sugar, chives, lemon juice and lemon pepper. Taste for seasoning and adjust as you prefer. Drizzle over fish before serving. If the butter hardens, cook in microwave briefly to loosen, approximately 15 seconds or so.
Step 4: Serve haddock with some extra chopped chives and drizzle the sauce over the fish. Use any leftover sauce for your rice, noodle or potatoes.
Recipe Testing Tips
- Pat the fish very dry.This is the most important step in this recipe. Too much moisture prevents the seasoning from sticking to the fish and affects the final texture.
- Preheat your air fryer for at least 5 minutes. A fully preheated basket means the fish starts cooking the moment it makes contact, which helps set the coating and prevents sticking.
- Don't move the fish for the first 5 minutes. Haddock is a delicate fish and needs time to release naturally from the basket. Moving it too soon risks pulling the coating and causing it to stick to the basket.
- Cook in batches if needed. Crowding the basket traps steam and prevents even cooking. A second batch is worth the extra few minutes.
- Check temperature from the right angle. Insert your meat thermometer straight down from the top for thicker fillets. For thinner fillets, slide it in sideways through the side of the fillet. Fish is done at 145°F.
Frequently Asked Questions
Because this recipe has such a good sauce, I always make something to drizzle it over alongside the fish. Wide egg noodles are my personal favorite with this one, but mashed potatoes or steamed rice work equally well. For vegetables, Blackened Green Beans, Charred Broccoli and Sweet and Spicy Brussels Sprouts all cook on the stovetop while the fish air fries, making them perfect side dishes for this meal.
It is technically safe to cook fish from frozen but I don't recommend it here. Haddock is a soft, moist fish and cooking it from frozen releases too much moisture, making it very difficult to get a good result. I think it's worth taking the time to fully defrost it first.
If you didn't defrost overnight, you can place packaged fish in a large bowl of cold water. Check in about 30 minutes, (no ice crystals) and change the water if needed.
I rarely use a liner and especially not with fish. A liner prevents the juices from draining down through the basket, which keeps the fish too moist.
Yes, cod and pollock are both excellent substitutes. Cod has a similar mild flavor to haddock but is slightly firmer. Pollock is also mild and works well with this seasoning blend. Both tend to be a bit less expensive than haddock as well. For firmer fish like salmon, mahi mahi or tuna steak, have a look at my other air fryer fish recipes linked above.
This usually happens due to one of three things; the fish wasn't patted dry completely before seasoning, the air fryer wasn't fully preheated before the fish went in, or the fish was moved too soon during cooking.
Storage and Reheating
- Storage- Leftover haddock can be stored in an airtight container in the refrigerator for up to 2 days. Store the Lemon Chive Butter Sauce separately in a small covered container. The butter in the sauce may firm up when refrigerated. Just warm it briefly in the microwave for a few seconds and it will loosen right up.
- Reheating- Reheat the haddock in the air fryer at 350°F for 3-4 minutes for the best result. The microwave will work in a pinch but the texture won't be quite as good.
- Freezing- I don't recommend freezing cooked haddock. The texture of this delicate fish doesn't hold up well through freezing and thawing once cooked.

Notes
*If using frozen haddock, make sure it's fully defrosted without any ice crystals. Pat very dry with paper towel. Too much moisture will cause the fish to steam instead of fry.
*Cook in batches if needed. Crowding the basket traps steam and prevents even cooking. A second batch is worth the extra few minutes.
*Check temperature from the right angle. Insert your meat thermometer straight down from the top for thicker fillets. For thinner fillets, slide it in sideways through the side of the fillet. Fish is done at 145°F.
