Storage
Store leftover cheese puffs in an airtight container in the refrigerator for up to 3 days. To reheat, warm in a preheated oven at 350°F (175°C) for about 8-10 minutes to restore their crispiness. Avoid microwaving as it may make them soggy.

FAQs
Can I use fresh mashed potatoes instead of leftovers?
Yes, you can use fresh mashed potatoes, but let them cool completely before mixing to help the puffs hold their shape better while baking.
Can I freeze the cheese puffs?
Absolutely. Freeze baked puffs in a single layer on a baking sheet, then transfer to a freezer-safe bag. Reheat in the oven directly from frozen for best results.
