When you need a fast seafood dinner that still feels special, this 30-minute air fryer cod with buttered fava beans gets it done with minimal mess. The cod turns out flaky with lightly crisp edges, and the fava beans get a simple lemon-butter finish that tastes like spring on a plate.
Why This Air Fryer Recipe Works
Cod is lean, which makes it quick to cook and easy to overdo. The air fryer’s circulating heat helps the fillets cook evenly while keeping the outside lightly browned.
Meanwhile, fava beans only need a short simmer (or quick warm-through if they’re already cooked), then a toss in butter, garlic, and lemon. Everything finishes at about the same time, so dinner lands on the table fast.
Quick cook time: cod cooks in under 10 minutes in most air fryers.
Simple flavors: butter, lemon, and herbs work with mild cod and favas.
Easy cleanup: one air fryer basket plus one small saucepan.
Ingredients You’ll Need
Try to buy cod fillets that are similar thickness so they cook at the same pace. If you’re using frozen cod, thaw fully and pat dry before seasoning.
Garlic powder and paprika (for gentle color and warmth)
Lemon (zest and juice)
Fresh parsley (or dill), chopped
Fava beans (about 1 to 1 1/2 pounds fresh in pods, or 2 cups shelled; frozen shelled also works)
Unsalted butter
Garlic, minced
Pinch of red pepper flakes (optional)
If you’re starting with fresh fava beans: shell them, blanch 1 minute in salted boiling water, chill in ice water, then peel the skins. It’s a bit of prep, but the buttery texture is worth it.
How to Make 30-Minute Air Fryer Cod with Buttered Fava Beans in the Air Fryer
1) Prep the cod. Pat the cod fillets very dry with paper towels. Brush lightly with olive oil (or mist with spray). Season with salt, pepper, garlic powder, and paprika. Finely zest the lemon over the top.
2) Preheat the air fryer. Preheat to 400°F for 3 minutes. If your model doesn’t preheat, just start cooking and add 1–2 minutes to the cook time as needed.
3) Air fry the cod. Place cod in the basket in a single layer with space around each piece. Cook until the fish flakes easily and looks opaque in the center.
4) Make the buttered fava beans. While the cod cooks, melt butter in a small saucepan over medium-low heat. Add minced garlic and cook 30–45 seconds until fragrant. Add peeled fava beans (or thawed frozen favas) and a pinch of salt. Toss to coat and warm through, 2–4 minutes. Finish with lemon juice, black pepper, chopped parsley, and red pepper flakes if using.
5) Finish and serve. Plate the fava beans first, then top with cod. Squeeze more lemon over everything and add a little extra parsley.
Air Fryer Time and Temperature
Use this as a starting point, then adjust based on thickness. Cod fillets that are 1 inch thick usually land in the sweet spot.
Temperature: 400°F
Time: 7–10 minutes, depending on thickness
Flip? Optional. If your fillets are thick, flipping at the halfway mark can help even browning.
Cod is done when it turns opaque and flakes easily with a fork. If you use an instant-read thermometer, aim for about 145°F at the thickest part.
Tips for the Best Results
Small details make a big difference with lean fish.
Dry the fish well: moisture is the enemy of browning and can make the surface steam.
Don’t crowd the basket: cook in batches if needed so hot air can circulate.
Use even thickness: if one end is thin, tuck it under so the fillet cooks more evenly.
Watch the last 2 minutes: cod can go from tender to dry quickly.
Salt the favas lightly first: then finish with lemon so the flavor stays bright.
If the cod looks pale, it may simply need a little more surface oil. A quick mist before cooking helps, especially with very lean fillets.
Variations and Substitutions
This recipe stays flexible without losing its “butter + lemon + herbs” backbone.
Swap the fish: try haddock, pollock, or halibut (adjust cook time for thickness).
Different bean: sub lima beans, edamame, or peas if favas aren’t available.
Add a light crunch: sprinkle toasted panko on the finished fish (no heavy breading needed).
Herb changes: dill and chives are great with lemony butter.
Dairy-free: use olive oil in place of butter and add a little extra lemon zest.
What to Serve With It
Keep sides simple so the cod and favas stay front and center.
Steamed jasmine rice or fluffy couscous to soak up the butter-lemon sauce
Roasted baby potatoes or air fryer fingerlings
A crisp green salad with vinaigrette (arugula works especially well)
Warm crusty bread if you want the easiest option

Storage and Reheating
Cod is best right after cooking, but leftovers can still be tasty if reheated gently. Store cod and fava beans in separate airtight containers if possible.
Fridge: up to 2 days
Freezer: cod can be frozen, but texture is best fresh; favas freeze well
To reheat in the air fryer: set to 325°F and warm the cod for 3–5 minutes until just heated through. Reheat fava beans in a small pan on low with a splash of water or a tiny knob of butter so they don’t dry out. For more air fryer leftover tips, visit Air Fryer Reheating Guide.
FAQ
Can I use frozen cod in the air fryer? Yes, but thawing first gives the best texture and helps seasoning stick. If you must cook from frozen, expect uneven moisture and add time; check often near the end so it doesn’t dry out.
How do I keep cod from sticking to the air fryer basket? Lightly oil the basket or use perforated parchment made for air fryers. Also, make sure the fish is lightly oiled—dry, un-oiled spots tend to grab.
Do I need to bread the cod for it to get crispy? No. This recipe goes for lightly crisp edges and a flaky center, not a thick crust. Drying the fillets well and cooking at 400°F helps the surface brown without breading.
Are fava beans hard to prep? Fresh favas take a few steps: shell, blanch, and peel. Frozen shelled favas are the shortcut and still taste great once warmed in garlicky butter and lemon.
What if my cod is thick in the middle? Add 1–3 minutes and consider flipping halfway through. If the outside is browning too fast, drop the temperature to 375°F and finish cooking a little longer.
