Few dishes look as impressive and are as easy to make as cod foil parcels with green pesto and tomatoes. When you wrap the fish in foil with ripe tomatoes at the base and a generous spoonful of green pesto on top, something special happens in the air fryer — the concentrated heat presses the flavours together, and the little splash of white wine gently steams the fish so it ends up tender and juicy without the slightest dryness.

It’s a starter I come back to every time I have guests. It needs no preparation worth mentioning, everything goes into the air fryer in one go, and it looks elegant when the parcel is opened on the plate. The result: cod that flakes apart at the mere touch of a fork.

Why I love cod foil parcels with green pesto and tomatoes in the air fryer
The air fryer has a knack for concentrating the heat around the foil parcel so the fish steams in its own juices and the white wine. That means tender, juicy cod every time — and you avoid the dry, dull state that oven-baked fish often ends up in if you misjudge the time or temperature.
The combination of sweet, ripe tomatoes at the base and fresh green pesto on top gives the dish depth without drowning out the fish’s own flavour. The pesto oil seeps into the fish during cooking and leaves a delicate, herby layer that ties the whole dish together.
The difference between air fryer and oven
A traditional oven needs 10-15 minutes of preheating and takes 20-25 minutes to heat a fish parcel through. The air fryer skips the preheating almost entirely and is done in 12-14 minutes — a time saving of 30-40 per cent, and the fish cooks more evenly because the heat circulates closely around the parcel.
My kitchen test of cod foil parcels with green pesto and tomatoes
I’ve tested the dish several times in my Cosori Dual Blaze at 180 °C, and the sweet spot is 12-14 minutes depending on the thickness of the cod. At 13 minutes the core temperature hit 56 °C — exactly where the cod is firm yet still juicy and not the least bit dry. Two parcels fit nicely in the basket at the same time without needing to be moved around during cooking.
I quickly discovered that one tablespoon of white wine per parcel is plenty. Use more and the base turns soupy and the flavour gets diluted. A squeeze of fresh lemon over the fish just before serving lifts the dish noticeably — it isn’t necessary, but it’s the kind of small detail that makes the difference between good and fantastic.
Only salt the cod after it’s wrapped up with the tomatoes — if you salt it beforehand, the salt draws moisture out of the fish and the result turns dry.
Tips and tricks from the author: Morten Jensen
The typical mistakes and how to avoid them
The most common mistake is sealing the foil parcel too loosely, letting the steam escape during cooking. The result is dry fish and a base that never gets to caramelise the tomatoes properly. Fold the ends of the parcel together tightly and press the sides firmly — there must be no openings. Another classic is using frozen cod without patting it thoroughly dry with kitchen paper first; the extra liquid waters down the whole parcel and dilutes the flavour of the pesto.
The third mistake is overdoing the white wine. More is not better here — one tablespoon traps the heat nicely and adds aroma, but 50 ml boils the fish down into a soup that drains the pesto of its nuances. Stick to a small splash, and let the fish’s own juices do the work.
How to serve cod foil parcels with green pesto and tomatoes
The starter calls for a bit of bread to soak up the flavourful juices from the parcel. Serve with:
- Crusty country bread or toasted baguette
- A glass of dry white wine — ideally the same type as in the parcel
- A simple green salad with lemon vinaigrette
- A dollop of aioli on the side
- Fresh basil or parsley as garnish on top
Storage and reheating
The fish parcels taste best straight from the air fryer, but they keep for 1-2 days in the fridge in the sealed parcel. Reheat gently at 150 °C for 4-5 minutes directly in the air fryer — a higher temperature makes the fish dry and grainy. Don’t freeze the dish: the tomatoes turn to mush after thawing and the pesto loses both its colour and freshness.
With a fish parcel like this you have a starter that works every time and only needs ten minutes of your attention. Assemble the parcels well in advance, and let the air fryer take care of the rest while your guests take their seats at the table.
FAQ
Yes, but thaw it completely and pat it thoroughly dry with kitchen paper first. Otherwise the extra liquid waters down both the pesto and the tomatoes. Add 1-2 minutes to the cooking time if needed.
Yes, coley, haddock and salmon all work fine. Adjust the time to the thickness — salmon is typically done quicker than cod and coley.
Let your guests open the parcel themselves at the plate — it adds a lovely visual touch, and the aroma is only released at the table, making the experience more intense.

Fish parcel
How to make it
Preparation
- Rinse the 400 g cod fillet and pat dry with kitchen paper. Cut into 4 equal pieces.
- Cut 4 large pieces of foil for the parcels, big enough to seal tightly around the fish with room for steam.
- Halve the 200 g cherry tomatoes and finely chop the 1 clove garlic. Mix in a small bowl with 2 tbsp olive oil and 1 tsp dried oregano.
Assemble the parcels
- Divide the tomato mixture between the bases of the 4 pieces of foil.
- Place the pieces of fish on top of the tomatoes.
- Pour the 50 ml white wine evenly over the 4 parcels — roughly 12 ml per parcel.
- Seal the parcels tightly by gathering the foil at the top and folding the edges together, so the liquid doesn’t seep out during cooking.
Cooking in the air fryer
- Preheat the air fryer to 180 °C.
- Place the parcels in the air fryer basket in a single layer and cook for 12-14 minutes, until the fish is cooked through and flakes easily with a fork.
- Remove the parcels and let them rest unopened for 2 minutes, so the steam finishes the cooking.
Serving
- Open the parcels carefully with a knife — watch out for the hot steam from the white wine.
- Sprinkle with the 1 tbsp fresh basil leaves and serve straight away in the parcel or plated up.
Our notes for the recipe
Choose cod fillets of even thickness so they finish cooking at the same time. Thick pieces (3-4 cm) need the full 14 minutes, while thinner pieces are often done in 10-12 minutes. The fish is ready when it flakes easily with a fork and is opaque all the way through. Variation:
Swap the cod for salmon, wolffish or haddock. Red pesto or a homemade lemon pesto gives the dish a completely different flavour profile. Add black olives or capers to the base for a Mediterranean twist. Serving:
Serve as a starter just as it is, or turn it into a light main course with boiled potatoes, toasted bread to soak up the sauce, or a simple rocket salad with lemon. Foil tip:
Seal the parcels thoroughly — leaky parcels give you dry fish because the steam escapes. Test by turning the parcel over and checking for drips.
