Microwave cream, milk, butter, nutmeg, garlic and thyme in a medium microwave-safe jug on HIGH for 2 minutes or until just below boiling point. Stir well to melt butter; stand for 15 minutes. Discard garlic and thyme.
Meanwhile, preheat oven to 200°C/400°F. Grease a 2-litre (8-cup) shallow ovenproof dish.
Use a mandoline or V-slicer to slice potatoes thinly. Layer potato and cheddar in dish; pour cream mixture over the top. Cover dish with greased foil.
Bake, covered, for 45 minutes. Remove foil; sprinkle the potato bake with parmesan. Bake, uncovered, for a further 20 minutes or until potato is tender and browned. Stand for 10 minutes before serving, topped with extra thyme.
Use a floury variety of potato such as spunta, desiree or russet burbank for this recipe. You could use vintage cheddar or blue cheese instead of the smoked cheddar, if you like.Test Kitchen tip
