Why this recipe works

Celeriac needs longer than apple

Three side servings from a shallow dish about 18 × 14 cm. Weigh celeriac and apple peeled. Layer no deeper than 3 cm so the centre heats reliably.

Recipe

Air fryer celeriac apple gratin

Air fryer celeriac and apple gratin with Gouda and mustard cream. Precook thin celeriac slices, then layer with raw apple in a shallow dish.

Ingredients

3 servings

Method

  1. 1

    Prepare

    Slice celeriac about 3 mm thin. Boil about 8 minutes until nearly tender, then drain well. Slice apple thinly too.

  2. 2

    Mix and season

    Butter dish and loosely layer celeriac and apple. Mix milk, cream, mustard, salt and pepper and pour over. Grate Gouda and reserve. Use a heatproof dish suitable for the appliance, leaving space around it for airflow. Do not preheat with loose paper.

  3. 3

    Cook

    If required by the manufacturer, preheat for 3 minutes at 170 °C. Cook first about 20 minutes at 170 °C. Test slices with a knife. Add Gouda and finish about 5 minutes at 170 °C.

  4. 4

    Check and serve

    Bottom celeriac slices should be tender too. Remove with gloves and serve with sauce as a side. Golden cheese alone is not a doneness test.

Frequently asked questions

FAQ about Air fryer celeriac apple gratin

Not with the same timing. This method uses thin slices and a shallow layer.

A tart apple works well; no extra sugar is included.

No, without flour it remains an unthickened mustard cream served with the slices.
