There’s something especially comforting about turning leftover mashed potatoes into something completely new. These cheesy mashed potato puffs are golden and crisp on the outside, creamy and tender inside, and packed with melted cheese in every bite. They take simple leftover mashed potatoes and transform them into a warm, savory little treat that feels like a cross between a crispy potato croquette and the cozy side dishes that made family dinners feel special. With just a handful of everyday ingredients and about 30 minutes from start to finish, these potato puffs are an easy way to make leftovers feel exciting again.
They are wonderfully versatile, too. Serve them as a fun side dish alongside dinner, add them to a brunch spread, or put out a platter as a simple appetizer for family and friends. The combination of creamy mashed potatoes, melted cheddar or mozzarella, savory garlic, and a crisp breadcrumb coating makes these little puffs genuinely hard to resist.
Why You’ll Make These Again
The magic of these potato puffs is how easily ordinary mashed potatoes become something completely different. The mashed potatoes provide a soft, creamy center, while the shredded cheese melts throughout the mixture and gives every bite a rich, savory flavor. The egg helps hold everything together, while the breadcrumbs create the golden exterior that becomes wonderfully crisp in the oven. Garlic powder adds just enough savory seasoning to make the potatoes more flavorful without overpowering their comforting character.
The optional green onions add a fresh, lightly sharp contrast to the rich potatoes and cheese, but the recipe is just as delicious without them. Best of all, these puffs are baked rather than deep-fried, so you can get a beautifully golden exterior with very little oil. They are the kind of simple recipe that makes you want to save your leftover mashed potatoes instead of wondering what to do with them.
How This Comes Together
The preparation is wonderfully straightforward. Combine the mashed potatoes with cheese, egg, green onions, garlic powder, salt, and pepper, then shape the mixture into small balls or patties. Each one gets rolled in breadcrumbs before going onto a prepared baking sheet. The key to nicely shaped puffs is making sure the mashed potato mixture is firm enough to hold its shape. If your mashed potatoes are particularly soft or creamy, chilling the mixture briefly before shaping can make the process easier.
Once assembled, the puffs simply bake at 400°F until their breadcrumb coating becomes golden and crisp. A light spray of olive oil or cooking spray over the tops helps encourage that beautiful golden finish without requiring a lot of added fat. Let them cool slightly before serving so the centers have a chance to settle while remaining wonderfully warm and cheesy.
What You’ll Need
This recipe uses simple ingredients that are easy to keep on hand, especially if you already have leftover mashed potatoes in the refrigerator. Cheddar gives the puffs a classic sharp, cheesy flavor, while mozzarella creates a milder flavor with an especially melty center.
- 2 cups mashed potatoes
- 1 cup shredded cheddar or mozzarella cheese
- 1 large egg
- 1/2 cup breadcrumbs
- 1/4 cup chopped green onions, optional
- 1/2 tsp garlic powder
- Salt and pepper, to taste
- Olive oil or cooking spray
Step-by-Step Directions
1. Combine the Potato Mixture
In a large bowl, combine the mashed potatoes, shredded cheese, egg, chopped green onions, garlic powder, salt, and black pepper. Mix until everything is evenly incorporated.
2. Shape the Potato Puffs
Scoop out portions of the mixture and gently roll them between your hands to form small balls about 1–2 inches wide.
3. Coat with Breadcrumbs
Roll each potato ball in the breadcrumbs, turning gently until the entire outside is evenly coated.
4. Arrange on the Baking Sheet
Place the coated potato puffs on a parchment-lined baking sheet, leaving a little space between each one. Lightly spray the tops with olive oil or cooking spray.
5. Bake Until Golden
Bake in a 400°F oven for 20–25 minutes, until the puffs are golden brown and crisp on the outside.
6. Serve Warm
Remove from the oven and let the potato puffs cool slightly. Serve warm while the outside is crisp and the cheesy potato center is soft.
How to Serve Them
Serve these cheesy mashed potato puffs warm as a side dish, appetizer, or snack. They are especially delicious alongside a simple dipping sauce such as sour cream, ranch dressing, or a creamy garlic sauce.

For dinner, pair the puffs with roasted chicken, grilled meat, or a fresh green salad for a comforting meal. They also make a fun addition to brunch alongside eggs and fresh fruit. For another easy baked potato side with a beautifully crisp exterior, our Baked Garlic Parmesan Potato Wedges are just as comforting and crowd-pleasing.
Leftovers & Storage
Store leftover potato puffs in an airtight container in the refrigerator for up to 3 days. For the best texture, reheat them in the oven or air fryer rather than the microwave so the breadcrumb coating can crisp back up. Place refrigerated puffs on a baking sheet and warm them in a 375°F oven until heated through and crisp on the outside. They can also be reheated in an air fryer until hot and golden.
You can also prepare the shaped potato puffs ahead of time and keep them refrigerated until you are ready to bake them. This makes them especially convenient when preparing food for a gathering or when you want to get dinner components ready in advance.
Make Them Even Better (Pro Tips)
- Use cold or chilled mashed potatoes when possible — firmer potatoes are easier to shape into neat balls or patties.
- Don’t make the puffs too large — keeping them around 1–2 inches wide helps the exterior become crisp while the cheesy potato center stays soft.
- Coat each puff thoroughly with breadcrumbs so the entire exterior develops a crisp, golden crust during baking.
- Give the tops a light coating of olive oil or cooking spray before baking to encourage even browning and crispness.
- Don’t overcrowd the baking sheet — leaving a little space between the puffs allows the hot oven air to circulate around them.
- Let them cool for a few minutes after baking — the centers will be very hot and the brief resting time makes them easier to serve.
- Use cheddar for a sharper, more savory flavor or mozzarella for a milder, extra-melty result.
Easy Ways to Change It Up
- Cheddar and bacon: Add finely crumbled cooked bacon to the potato mixture for a smoky, savory variation that pairs beautifully with sharp cheddar.
- Herb and cheese: Stir in chopped parsley, chives, or dill along with the cheese for a fresher, more aromatic version.
- Jalapeño cheddar: Add finely chopped jalapeño and use cheddar cheese for a mildly spicy potato puff with plenty of savory flavor.
- Parmesan crust: Mix a little grated Parmesan into the breadcrumbs for an extra savory, deeply browned coating.
- Loaded potato puffs: Add cooked bacon, chopped green onions, and extra cheddar to the mixture for a bite-sized version of a classic loaded baked potato.
Quick Questions
Can I use leftover mashed potatoes?
Absolutely. Leftover mashed potatoes are ideal for this recipe because they are already cooked and seasoned. Cold mashed potatoes are often easier to shape than freshly made, softer potatoes. If your leftovers are especially loose or creamy, chill them before shaping to make the mixture easier to handle.
Can I make these without breadcrumbs?
Yes, although the breadcrumbs are what give the puffs their signature crisp exterior. You can leave them off for a softer baked potato puff, but the finished texture will be less crunchy on the outside.
Can I make these in an air fryer?
Yes. Arrange the coated potato puffs in the air fryer basket in a single layer, leaving space between them for the hot air to circulate. Cook until golden and crisp on the outside, checking them during cooking because air fryers can vary in temperature and cooking speed.
