Can I prepare the potato roll ahead of time?
Yes, assemble the roll-up up to 4 hours ahead, cover with plastic wrap, and refrigerate. Bake just before serving, adding 5–10 minutes to the bake time if starting from cold.
What's the best way to slice potatoes thinly for this recipe?
Use a mandoline slicer or the thin-slice blade on a food processor to get consistent 1/8-inch slices. Soak slices in cold water for 10 minutes to remove excess starch and prevent browning.
How do I know when the potato roll is done baking?
The potato exterior should be golden brown and crispy, and a fork should easily pierce the potatoes. Internal temperature should reach 160°F if using raw ham, or 140°F if using pre-cooked deli ham.
Can I use a different type of ham or cheese?
Yes. Prosciutto, Black Forest ham, or smoked turkey work well. For cheese, try sharp cheddar, Gruyère, or a blend instead of mozzarella.
How do I store and reheat leftovers?
Store covered in the refrigerator for up to 3 days. Reheat at 350°F for 10–15 minutes until warmed through.
