Step 1

Preheat oven to 400 F.

Step 2

Grease the bottom of the medium casserole pan with melted butter.

Step 3

Spread 1/4 of the sliced potatoes in an even layer on the bottom of the pan. Sprinkle the potatoes with 1/8 teaspoon salt, then top with 1 minced garlic clove, 1/4 cup of grated Parmesan cheese, 1/4 amount of thyme leaves (removed from sprigs). Top with 1/4 cup of heavy creamy, pouring it evenly over the potatoes.

Repeat layers 3 more times (total of 4 layers of potatoes). For the last layer, use 1/2 cup of shredded Parmesan cheese (or more).

Step 5

Bake at 400 F, uncovered, for about 1 hour, or until the potatoes are cooked through.
