Preheat oven to 350°F/180°C (all oven types).

Brush muffin tin with butter: Melt butter in a saucepan over medium heat then use what you need to lightly brush the muffin tin holes with butter.

Cream sauce: Into the remaining butter, add garlic and cook for 20 seconds. Add cream and salt then bring to a simmer. Simmer for 30 seconds, then remove from stove and keep warm.

Slice potato: Peel potatoes. Trim base so it stands upright. Then cut into cylinder shapes that fit the muffin tin. Cut into 2mm/⅒" slices using a mandolin or sharp knife.

Assemble stacks: Place potato slices into the muffin tin so they go halfway up the muffin tin holes. Try to match by size to make them into neat stacks.

Cream: Drizzle each potato stack with 1 tsp of cream mixture - use ½ of the mixture.

Cheese slice: Top with cheese slice.

Top with potato, cream then thyme: Top each stack with remaining potato slices so the height is about 1cm / ⅓" above the rim of the muffin tin. Drizzle with remaining cream mixture and sprinkle with most of the thyme (reserve some for topping).

Baked 40 minutes: Cover loosely with foil and bake for 40 minutes or until potato is cooked through.

Top with cheese, bake 10 minutes: Remove from oven, sprinkle with shredded cheese and bake without foil for 10 minutes or until golden.

Garnish with thyme: Sprinkle with remaining thyme.

Stand 5 minutes then remove to serve.
