Can I prepare this casserole ahead of time?
Yes, assemble the casserole up to 8 hours ahead, cover, and refrigerate. Add 10-15 minutes to baking time if baking from cold.
How thin should I slice the pork and potatoes?
Slice both about 1/8 inch thick for even cooking. Use a mandoline or sharp knife to ensure consistent thickness.
What temperature should the pork reach for doneness?
The pork should reach an internal temperature of 145°F (63°C). The mozzarella topping browning indicates the casserole is done.
Can I use a different cheese instead of mozzarella?
Yes, mild cheddar or a blend of cheddar and gruyere work well, though mozzarella's mild flavor is traditional.
How do I know when the potatoes are tender?
Pierce the top layer with a fork; potatoes should slide through easily. The cheese should be golden brown and bubbly.
