Ingredients
>
cooking spray
>
1 1/2 lbs Yukon Gold potatoes
>
1 lb parsnips
>
1 cup fat-free half and half
>
1 cup whole milk
>
1 tsp garlic powder
>
2 tsp fresh thyme leaves
>
6 oz Gruyère cheese, grated
Steps
1
Preheat oven to 350°F. Coat a 2-quart baking dish with cooking spray. Peel the potatoes and the parsnips. Using a mandoline, cut potatoes and parsnips into ⅛-inch-thick slices.
2
In a large heavy-bottomed pot, combine the half & half, milk, garlic powder, and thyme. Season with salt and pepper. Add the potatoes and parsnips and heat to a boil on high. Reduce heat and simmer 5‒6 min., until potatoes are almost tender and liquid has thickened. Remove from heat.
3
Spoon half of the mixture into the greased baking dish, spreading in an even layer. Top with half of the Gruyère. Repeat layering. Bake 50‒60 min., until golden brown. Let cool 10 min. before serving.

A food processor fitted with a slicing blade can also get the vegetables paper-thin in a flash.
