Use fresh cheese curds whenever possible for the authentic squeaky texture. If you can’t find them, small pieces of mozzarella cheese can be a substitute, though the texture will differ. Keep the fries hot and crisp before assembling to prevent sogginess. Double-fry fries for extra crispiness or bake at a high temperature with a light coating of oil. Store leftovers in an airtight container in the refrigerator for up to 2 days and reheat fries in the oven to restore crispiness. For variations, try vegetarian gravy alternatives, add spicy hot sauce, or top with bacon bits and herbs.
