  • Step 1

    Spread butter in base of pot. Sprinkle over caster sugar. Place onion halves cut side up in pot in an even layer and squeeze in as many pieces as possible as they will shrink once cooked. Season to taste.

  • Step 2

    Move slider to AIR FRY/COOKER position. Select SEAR/SAUTÈ and set temperature to 4. Select START/STOP to begin. Heat until the butter and sugar melt together and turn a golden-brown colour, (approximately 3 minutes).

  • Step 3

    Reduce temperature to 3, add 150ml water and thyme sprigs. Close lid and allow to simmer occasionally opening lid to check until water has evaporated and there is a golden caramel forming again. Select START/STOP to turn off SEAR/SAUTÉ.

  • Step 4

    Carefully turn the onion halves over and add remaining water to pot. Select SEAR/SAUTÈ and set temperature to 3. Select START/STOP to begin cooking again. Close lid and allow to simmer, opening lid to check when onions are tender, water has evaporated and there is a deep golden brown caramel forming. The onions will take 15-20 minutes to cook altogether. Select START/STOP to turn off SEAR/SAUTÉ.

  • Step 5

    Place puff pastry circle over onions and use a wooden spoon or silicone spatula to tuck pastry in around edges. Prick pastry a few times all over with a fork.

  • Step 6

    Close lid and select AIR FRY, set temperature to 200°C and time to 15 minutes. Press START/STOP to begin cooking.
