Notes

• For extra flavor, add bell peppers or bacon. Use a large sheet pan for crispier potatoes.
• Make sure your potatoes are cut into evenly sized pieces so they cook at the same rate.
• Spread everything out in a single layer for crispy potatoes instead of steaming them.
• Adding the cheese during the last few minutes keeps it perfectly melted without burning.
