Position a rack in the center of the oven and preheat to 175°C. Generously spray a 12-cup muffin tin with cooking spray.
02 -
In a large bowl, whisk together Parmesan, half-and-half, fresh thyme, garlic powder, kosher salt, black pepper, and smoked paprika. Add potato slices and toss until evenly coated.
03 -
Form stacks by layering 2 potato slices into each muffin cup, then place one ham square on top. Repeat layering four times with potatoes and ham, finishing each stack with one potato slice. Pour any remaining Parmesan mixture over and around the stacks, then tightly cover the pan with aluminum foil.
04 -
Bake the stacks for 35 minutes, covered with foil, allowing potatoes to cook through and absorb flavors.
05 -
Remove foil, sprinkle shredded cheddar around and on top of the stacks. Return to oven and bake uncovered for an additional 10 to 15 minutes, or until cheese melts and begins to brown at the edges. Let rest in pan for 5 minutes.

Use an offset spatula to carefully transfer each stack to a serving platter. Garnish with chopped fresh parsley before serving.
