Step‑by‑Step Instructions for Leftover Mashed Potato Cheese Puffs
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature will ensure that your Cheesy Leftover Mashed Potato Puffs bake evenly, resulting in that perfectly crisp exterior. While the oven heats up, gather all your ingredients and equipment, including a large mixing bowl, measuring cups, and a parchment-lined baking sheet.
Step 2: Mix the Ingredients
In a large mixing bowl, combine your leftover mashed potatoes, shredded cheese, flour, egg, and your choice of seasonings, such as garlic powder, salt, and pepper. Using a spatula or wooden spoon, mix everything together until it forms a smooth, cohesive mixture. Take a moment to admire the cheesy goodness that’s about to become your delightful puffs!
Step 3: Shape the Puffs
With your mixture ready, scoop out golf ball-sized portions of the mixture using your hands or a cookie scoop. Gently roll each scoop into a ball and place it on the prepared parchment-lined baking sheet. Make sure to leave some space between each puff to allow for even cooking and puffing up in the oven.
Step 4: Bake the Puffs
Once all your puffs are shaped and on the baking sheet, slide them into the preheated oven. Bake for 20-25 minutes, or until they are golden brown and crispy on the outside. You’ll know they’re ready when they turn a lovely golden hue and give off a delicious, cheesy aroma that wafts through your kitchen.
Step 5: Cool and Serve
After baking, remove the Cheesy Leftover Mashed Potato Puffs from the oven and let them cool slightly on the baking sheet for about 5 minutes. This brief cooling period will help them set. Serve them warm with your favorite dipping sauces, like ranch or sour cream, and watch them disappear in a flash!

How to Store and Freeze Leftover Mashed Potato Cheese Puffs
Fridge: Store any leftover puffs in an airtight container for up to 3 days. This keeps them fresh while maintaining their delightful texture.
Freezer: For longer storage, freeze uncooked puffs arranged on a baking sheet until firm, then transfer to a freezer bag for up to 3 months. Bake from frozen, adding a few extra minutes to the cooking time.
Reheating: To reheat, bake leftover puffs at 375°F (190°C) for about 10-15 minutes. This helps restore their crispy exterior and warms them through.
Make-Ahead: Shape the puffs ahead of time and refrigerate them until you’re ready to bake. This is a perfect strategy for effortless entertaining!

Leftover Mashed Potato Cheese Puffs Recipe FAQs
How do I choose the right leftover mashed potatoes?
Absolutely! For the best results, use smooth, creamy leftover mashed potatoes without lumps, which helps ensure a uniform texture in your puffs. If you don’t have any leftovers, store-bought mashed potatoes are a great substitute and will save time!
What’s the best way to store leftover puffs?
To keep your leftover puffs fresh, store them in an airtight container in the fridge for up to 3 days. For longer preservation, you can freeze the uncooked puffs. Arrange them on a baking sheet until firm, then transfer them to a freezer bag where they can last up to 3 months.
Can I freeze the puffs after baking?
