Step‑by‑Step Instructions for Leftover Mashed Potato Cheese Puffs
Step 1: Gather Ingredients
Start by gathering all your ingredients to make these delightful Leftover Mashed Potato Cheese Puffs. Ensure your leftover mashed potatoes are at room temperature, as this will make the mixing process easier. Have your shredded cheese, breadcrumbs, egg, garlic powder, onion powder, salt, and pepper ready to go in a clean workspace.
Step 2: Mix Ingredients Together
In a large mixing bowl, combine the room-temperature leftover mashed potatoes, shredded cheese, breadcrumbs, and the egg. Sprinkle in the garlic powder, onion powder, salt, and pepper to taste. Mix everything together until fully combined. You want the mixture to be uniform and slightly sticky, which will help shape them into puffs later.
Step 3: Shape the Puffs
With your mixture ready, take small portions and roll them into balls or pat them into small discs about 1 to 2 inches in diameter. Make sure to keep your hands lightly damp to prevent sticking. This step is key to forming the perfect little puffs that will be crispy on the outside and cheesy on the inside.
Step 4: Heat the Oil
In a large frying pan, add enough olive oil to cover the bottom and heat over medium heat. You want the oil to reach about 350°F (175°C) for optimal frying. This temperature ensures that the Leftover Mashed Potato Cheese Puffs will fry up nice and crispy without absorbing too much oil, keeping them light.
Step 5: Fry the Puffs
Carefully place the shaped puffs into the hot oil in batches, making sure not to overcrowd the pan. Fry each puff for approximately 3 to 4 minutes on one side until they turn golden brown. Once browned, gently flip using a spatula and cook for another 3 to 4 minutes until both sides are deliciously crispy.
Step 6: Drain and Serve
After frying, use a slotted spoon to remove the Leftover Mashed Potato Cheese Puffs from the oil and let them drain on a plate lined with paper towels. This will help absorb any excess oil. Serve them warm, either on their own or with your favorite dipping sauce for an extra flavor kick.

Leftover Mashed Potato Cheese Puffs Recipe FAQs
What type of mashed potatoes should I use?
Absolutely! For the best results, use cold leftover mashed potatoes right from the fridge. This makes it easier to shape the puffs without them being too sticky. If you're making fresh mashed potatoes for this recipe, allow them to cool down significantly before proceeding.
How do I store leftover mashed potato cheese puffs?
To keep your delicious cheese puffs fresh, store them in an airtight container in the fridge for up to 3 days. Make sure they are completely cooled before sealing to prevent moisture buildup. When you're ready to enjoy them, a quick reheat in the oven for about 10-15 minutes restores their crispy exterior.
Can I freeze leftover mashed potato cheese puffs?
Yes, you can! To freeze, I recommend laying the puffs out on a baking sheet in a single layer and placing them in the freezer for about an hour until they’re firm. Once they've firmed up, transfer them to a resealable freezer bag, where they can remain good for up to 2 months. When you want to enjoy them, just fry them straight from frozen for a quick snack!
What can I do if my puffs are falling apart?
Very! If your mixture feels too loose, try adding a touch more breadcrumbs to help bind it together. Additionally, ensure that your leftover mashed potatoes are adequately cooled; warm potatoes can lead to less structured puffs. If they’re still falling apart when frying, a little more egg or even flour can help hold everything together!
Can pets enjoy any of the ingredients in these cheese puffs?
While the ingredients like mashed potatoes and some cheese are safe for most pets in moderation, it's best to avoid giving your furry friends anything with garlic, onion, or added seasonings. Some cheeses can upset their tummy too. Always check with your vet if you’re uncertain!
