Use frozen potatoes and vegetables straight from the freezer. Start meat or fish fresh or fully thawed. Allow packet preheating and any longer cooking time; thawing meat or fish takes extra time.

Method

  1. Start the frozen potato cubes

    Weigh 350 g potato cubes for 1 portions in total. Split all listed ingredients equally between 1 one-portion cooking batches. Toss the plain frozen potato cubes with half the measured oil for that batch. Fit the crisper plate and spread the cubes loosely in one drawer. AIR FRY at 200°C for 25–30 minutes, shaking regularly. Follow any longer packet time; the centres must be hot and soft. Do not use coated chips or wedges with these nutrition values.

  2. Cook the fish

    Pat the fully thawed tuna dry. Brush with the remaining half of the oil for this batch and put in the second drawer with the crisper plate fitted. AIR FRY at 180°C for about 8–12 minutes, turning halfway. Thickness affects timing: check the centre reaches 75°C for 30 seconds and cook longer if needed. These settings are for thawed fish; defrost in the fridge according to the packet before starting.

  3. Add the frozen vegetables

    Add the frozen broccoli to the potato drawer with 15 minutes left, leaving space for airflow. If the potato packet time is shorter than 15 minutes, start both together. Shake during cooking. Remove the potatoes if they finish first and continue cooking the broccoli until tender and steaming hot throughout. Follow any longer packet instruction. Divide each finished batch into equal portions.

Reference values and assumptions
  • Tuna steak, raw, fully thawed. Reference values are per 100 g as sold, excluding ice glaze. Weigh after defrosting and draining; do not use cooked-weight values. Other packets may differ. Source
  • Lemon juice. Fibre uses the Matvaretabellen reference for lemon juice bottled; the other values retain the CoFID estimate. Source

Recipe notes

  • Timings are starting estimates for small pieces. Cook until tender and follow the meat or fish doneness checks.
  • Keep the broccoli frozen and follow any longer cooking time on the Freshona packet.
  • Use plain frozen potato cubes without added oil. Measure the oil for each batch; oil-coated chips or wedges change the nutrition.
