Peel the potatoes and keep in a bowl under cold water, when ready you need to VERY thinly slice them, I suggest a mandolin for this but please take care they are also known as 'Japanese finger slicers'. If you do this by hand you must keep the slices consistent in size

Now drain the sliced potato and allow the excess water to drain away, drizzle olive oil and seasoning in a non-stick frying pan. Then start arranging the potato slices around the edge slightly overlapping them. When you have completed the circle if there is a gap in the centre carefully lay slices in there.

Season the top of the potatoes and pick thyme, drizzle more olive oil and then repeat another 2 layers. Sit pan over a medium heat and cook until the bottom is lovely and golden, add a few knobs of butter to help the colour, this will hopefully set the slices so them stick together. Be careful as you lit the edge to check for the colour.

To turn the galette you must firstly be very careful not to spill hot fat on you, sit a large plate over the pan, sit a tea towel over the plate. Grip the bottom of the pan so that the pan and plate are firmly together and in one confident movement turn through 180 degrees.

Return the pan to the stove oil, butter and slide the galette back on the underside, cook this side until lovely and golden brown again. The galette will need to be oven cooked to finish the centre so if you are happy to you can put your pan in the oven, I made 2 this time so I transferred the potato to a lined baking tray, repeated the process with the other galette and then baked at 180c for 10 minutes

You can serve immediately or simply re-heat later in the day, so these are perfect for saving you time later when you finish your meal, you see me looking very pleased in the second image and a nice stylish close up of the very delicious Pommes Anna.
