Position oven rack in center of oven. Preheat oven to 375°F.

Butter eight (8) regular-sized non-stick muffin cups with butter. Set aside.

In small, microwave-safe bowl, melt the butter. Add the olive oil, liquid chicken bouillon, garlic salt, onion powder, thyme, parsley, nutmeg, salt, and pepper. Stir well to mix. Stir in the Parmesan and Cheddar cheeses along with the milk or cream.

Choose potatoes that are not overly starchy and that will hold their shape after cooking – e.g., Yukon Gold or an all-purpose round white variety. Select potatoes the size that, when sliced horizontally, the slices will easily fit flat into the muffin cups. Using a mandolin, slice potatoes horizontally into slices 3/16” thick. Place half the potato slices in large bowl. Add half the mixed butter, seasonings, and cheese ingredients. Using hands, toss the potatoes in the mixture until the slices are well coated. Add the remaining potato slices and butter mixture and continue mixing until the potato slices are coated with the mixture. Either create the stacks of potatoes in hands and place in buttered muffin cups or individually stack the potato slices directly in the muffin tin cups, stacking the slices as evenly as possible until they are about ¾ - 1” above the muffin cup rims. The stacks will shrink a bit during the roasting but building them a little higher than the muffin cup rim will ensure a good sized potato stack when cooked.

Bake the potato stacks for about 25 minutes, then sprinkle each stack with additional grated Parmesan cheese and a light sprinkle of paprika. Bake for 20 minutes longer, or until the tops of the potato stacks are golden and crispy, and a skewer or thin knife inserted in center of a stack indicates potatoes are tender and cooked through. Remove from oven and let rest for 5 minutes then carefully run the tip of a knife around the perimeter of each muffin cup to ensure the potato stacks are loose for easy removal. With the aid of a fork, or soup spoon, and the tip of the knife, carefully remove each potato stack and serve immediately sprinkled with additional finely-grated Parmesan cheese and fresh parsley.
