You’ll need these…




Lightly grease a 20cm round cake pan. Arrange potatoes upright in stacks of slices around the edge of the pan, then work towards the centre to completely cover the base of the pan, scattering with thyme as you go.


Combine soup mix, cream, milk and parmesan in a large jug; season with salt and pepper. Pour mixture evenly over the potatoes and let it settle. Cover the pan with foil. Place pan in the inner pot. Cover with the instant pot’s air fryer lid. Select Bake and set temperature to 180°C and time for 2 hours.


Remove the foil, then re-cover with the air fryer lid. Select Bake and set temperature to 200°C and time for 30 minutes; Bake until potato is tender and top is golden.


Stand bake for 10 minutes before serving. Serve topped with extra thyme leaves.

Fold two lengths of foil into long strips and cross under base of the cake pan to act as a sling; this will make it easier to lower and lift the pan into and out of the inner pot.

The Ultimate Instant Pot

One appliance, nine functions.

What is an Instant Pot?

An Instant Pot is a multicooker appliance that can be used across a broad range of cooking applications, and combines many kitchen appliances into the one space-saving machine.

A multicooker will streamline the cooking process for a variety of cooking functions – roast, air fry, pressure cook, slow cook, bake and more. Less hands-on cooking and less washing-up throughout the cooking process are the rewards when using a multicooker. All this time saved means you’ll be getting delicious meals on the table a lot more quickly.

There are an assortment of Instant Pot models for sale in the marketplace. For this recipe, we used the 8-litre Instant Pot Duo Crisp + Air Fryer. Always read the safety and operating instructions for your specific model.
