What you need to make it
Ingredient notes

Ingredient substitutions
- Butter can be swapped for olive oil
- Fresh basil can be omitted or switched for another fresh herb like thyme
- Black pepper can be fresh ground or pre-ground
- Sea salt flakes can be swapped for fine table salt at half the amount stated
- Cod can be swapped for another white fish like haddock, bass or tilapia.
How to make it

- Top with sliced potato, tomato and lemon
- Place the cod on top
- Squeeze over half a lemon
- Season with black pepper and sea salt flakes
- Top with basil
- Wrap up the foil packs tightly and place on a sheet pan or other oven-safe dish. Cook in the middle of the oven for 25 minutes.
- Bring out the packs from the oven and let sit for 5 minutes. Serve still wrapped and let your guests unwrap their dinner themselves
Tips & tricks
- Use frozen cod - this is the best way to ensure it's not overcooked and cooks in about the same time as the potatoes
- Slice the potatoes thin to make sure they cook through
- Test your fish and potatoes by using a cake tester and sticking it into the package. This way you don't need to open the package to test it.
- Make it on the grill instead and it will cook in about the same time
- Make it dairy free by using olive oil instead of butter
Recipe FAQ
Do things cook faster wrapped in foil?
No, it's actually the opposite. Foil reflects heat and so the food inside the foil packet will get less of it. However, wrapping food in foil ensures the moisture is trapped inside and the longer cook time tends to make food juicier and tastier.
Which side of aluminium foil should touch the food?
It doesn't matter! The difference in shiny vs not shiny comes from the manufacturing process but makes no difference to the finished product.
How do you tell if baked cod is done?
Cod is done when it flakes easily when a cake tester or fork is put through it. It should be white all the way through.
