This small cheesy snack has been a family favorite whenever I need to turn leftover mashed potatoes into something exciting. I discovered the basic combination in a sleepy weeknight moment when I had two cups of mashed potatoes left over from a Sunday roast. Instead of reheating them plain I mixed in sharp cheddar and a couple of pantry staples and formed small rounds. The results were golden outside and pillowy inside with a bright cheddar pull that even my picky niece loved. The texture is creamy within and slightly crisp on the surface which makes each bite satisfying.

I remember serving these at a casual gathering where everyone reached for more than one. They work equally well as a snack with a dipping sauce or as a playful side for a burger plate. The formula is forgiving which makes it a perfect go to for busy cooks. I like to make a double batch when I have company because they keep well in the refrigerator and reheat beautifully in an air fryer or oven for a few minutes to restore the crisp exterior.

Ingredients

• Mashed potatoes 2 cups prepared mashed potatoes made with milk and butter if you have them. For best texture use slightly cooled potatoes that are smooth and not overly runny. If using store bought instant mash choose a full flavor brand for better taste.
• Sharp cheddar cheese 1 cup shredded sharp cheddar. A block cheddar shredded at home melts more uniformly than pre shredded blends. Choose a sharp variety for a bright cheesy note that stands up to the potato.
• Eggs 2 large eggs to bind the mixture. Room temperature eggs incorporate more easily and help create a tender interior.
• All purpose flour 1/2 cup to give structure. If you want a lighter texture you can add a little more but start with 1 2 3 cup and adjust as needed.
• Salt 1 teaspoon kosher or sea salt to season. If your mashed potatoes were already salted taste before adding the full amount.
• Black pepper 1/2 teaspoon freshly ground for balanced spice. Freshly ground pepper has more aroma than pre ground pepper.
• Oil or cooking spray for frying or baking. Use a neutral oil like vegetable or canola for pan frying or spray a baking sheet if baking.

Instructions

Combine the basePlace 2 cups of prepared mashed potatoes into a large mixing bowl. Add 1 cup shredded sharp cheddar, 2 large eggs that are at room temperature, 1/2 cup all purpose flour, 1 teaspoon salt and 1/2 teaspoon black pepper. Use a sturdy spoon or spatula to fold until the mixture is cohesive. If the mixture feels too loose add additional flour one tablespoon at a time until you can form small balls without them falling apart. This step is about balance between moisture and binding.Shape the puffsLightly flour your hands and scoop about 1 tablespoon of mixture per puff for bite size or 2 tablespoons for larger puffs. Roll gently to form smooth rounds. Placing formed rounds on a parchment lined tray helps them keep their shape until cooking. If making ahead refrigerate the tray for at least 30 minutes to firm the exterior before cooking.Choose your cooking methodFor pan frying heat 2 tablespoons of neutral oil in a skillet over medium heat and cook in batches for 3 to 4 minutes per side until golden and crisp. For baking preheat the oven to 400 degrees Fahrenheit and bake on a parchment lined baking sheet for 15 to 18 minutes turning once halfway through. For air frying preheat at 375 degrees Fahrenheit and air fry for 8 to 10 minutes, turning once, until golden. Visual cues are a golden surface and a warm center.Finish and serveTransfer cooked puffs to a wire rack briefly to avoid sogginess. Serve warm with a dipping sauce such as sour cream and chive, a tangy mustard dip, or a simple marinara. Leftovers can be chilled and reheated crisp in an oven or air fryer.

Storage Tips

To store uncooked shaped puffs place them on a parchment lined tray and cover with plastic wrap then refrigerate for up to 24 hours before cooking. Cooked puffs will keep in an airtight container in the refrigerator for three to four days. For freezing set shaped puffs on a tray and place in the freezer until firm about one hour then transfer to a resealable freezer bag and label with the date. When reheating from frozen pop them into a preheated oven at 375 degrees Fahrenheit for 10 to 12 minutes or air fry at 360 degrees Fahrenheit until heated through and crisp. Avoid microwaving unless you plan to finish in the oven for texture recovery.

Ingredient Substitutions

If you need to avoid gluten replace the all purpose flour with an equal amount of a certified gluten free flour blend or with 1 2 cup of rice flour plus 1 2 teaspoon xanthan gum for structure. To make the puffs dairy free choose a dairy free cheese alternative that melts well and adjust salt since those products can vary in seasoning. For egg free adaptations use a commercial egg replacer or 1 4 cup aquafaba per egg but expect a slightly different texture and plan to chill the shaped pieces longer before cooking. For more flavor fold in finely chopped green onions, cooked crumbled bacon, or a pinch of smoked paprika to alter the taste profile.

Serving Suggestions

These puffs pair well with bright condiments. Try a lemony yogurt dip, a herbed sour cream, or a tomato based sauce. For more substantial plates serve alongside a crisp salad dressed with an acid forward vinaigrette or place them next to roasted vegetables and a protein for a cozy meal. Garnish with chopped chives or parsley for contrast. For party service present them on a platter with small bowls of assorted dips to invite guests to mix and match flavors.

Cultural Background

The idea of transforming mashed potato leftovers into small fried or baked bites can be found in many food cultures where nothing is wasted and leftovers are reinvented. Variations are common across Europe and the Americas from potato cakes to croquettes. The addition of cheese gives an American comfort food twist and sharp cheddar adds the kind of boldness common in modern home cooking where convenience meets rich flavor. This dish sits in the lineage of thrifty cooking that elevates humble ingredients through technique.

Seasonal Adaptations

Spring calls for folding in fresh herbs like dill and chives and serving with a lemony sour cream. In summer consider adding finely diced roasted peppers and pairing with a cool tomato salad. For autumn add a touch of nutmeg and swap in a smoked cheddar to compliment roasted squash. Winter invites heartier additions such as caramelized onions or chopped cooked bacon and a warm mustard dip. Small changes in seasoning and garnish adapt the puffs to seasonal produce while keeping the base method intact.

Meal Prep Tips

Shape the puffs and store them on a tray covered with plastic wrap in the refrigerator for up to 24 hours so cooking becomes an assembly task. For busy weeks make a large batch then freeze uncooked puffs for quick reheating. When cooking from frozen add a couple of minutes to the bake time and avoid overcrowding to ensure even crisping. Use an oven thermometer to confirm temperature and a nonstick surface or light oil spray to prevent sticking while using minimal fat.

There is something joyful about taking a humble leftover and turning it into something people reach for. These small rounds are approachable, forgiving, and full of comfort. I hope you find them as satisfying as we do and that they become one of your simple go to solutions for leftover mashed potatoes.
