Those cold mashed potatoes sitting in your fridge are about to become the star of the show. This recipe for crispy mashed potato cheese puffs transforms boring leftovers into golden snacks that are crisp on the outside and gooey in the middle. These puffs are fast family favorites perfect for after-school munchies or a party platter that disappears in minutes.
The first time I made these was after a holiday feast when the fridge was overflowing with extra mash. Now everyone in my family cheers when I suggest cheese puffs for dinner or a snack.
Ingredients
- Cold mashed potatoes: from the fridge keep puffs easy to shape and help the texture stay perfect
- Shredded cheddar cheese: choose a sharp version for big cheesy flavor and grate it fresh if you can
- Eggs: at room temperature let everything mix together smoothly
- All-purpose flour: just enough to bind the puffs and give them structure
- Salt: make sure to taste your potatoes before adding more since leftovers may already have seasoning
- Black pepper: freshly cracked offers the best pop of flavor
- Garlic powder: a sprinkle adds savory depth and warmth
- Breadcrumbs: panko makes them extra crunchy but any variety works in a pinch
Step-by-Step Instructions
- Mix the Dough:
- Add your cold mashed potatoes to a large bowl. Pour in the cheese eggs flour salt pepper and garlic powder. Using your hands mix everything together until you have a thick sticky dough that holds its shape. If the mixture is too wet sprinkle in a little more flour. If it is dry add a splash of milk.
- Shape and Coat the Puffs:
- Scoop out a tablespoon of dough and roll it into a smooth ball about the size of a ping pong ball. Roll each ball in a plate of breadcrumbs until fully coated pressing gently so they stick all over. Set them on a lined baking sheet.
- Bake to Crispy Perfection:
- Arrange the puffs with a bit of space between each one on a parchment lined baking tray. Bake in a preheated 400 degree oven for twenty to twenty five minutes until the puffs are deep golden and the aroma turns irresistible. If you like an even crunchier texture turn them halfway through baking.

I am obsessed with adding chopped chives to the mix. Once my daughter and I made these together on a rainy day and now she asks for “rainy day puffs” whenever clouds roll in.
Storage Tips
Keep leftovers in an airtight container in the fridge for up to three days. When ready to reheat pop them in a 350 degree oven or an air fryer for five minutes to get the crunchy exterior back. Avoid the microwave for these cheese puffs as it makes them soggy.
Ingredient Substitutions
Swap cheddar cheese for your favorite melting cheese like gouda or pepper jack for extra kick or even smoked provolone for depth. For a gluten free version use a one to one gluten free flour and gluten free breadcrumbs. You can add cooked crumbled bacon diced ham or fresh herbs like parsley or green onion for a flavor twist.
Serving Suggestions
Serve cheese puffs as a party appetizer with a bowl of sour cream and chives or classic ketchup. They pair beautifully with tomato soup or make a fun addition to a brunch buffet. Try them as a side with grilled chicken or alongside a simple salad for an easy weeknight dinner.

Recipe FAQs
- → Can I freeze these puffs?
Yes, freeze the baked puffs on a tray to prevent sticking, then store in a freezer bag. Reheat from frozen in a 375°F oven for about 10 minutes for best texture.
- → What if I don't have leftover mashed potatoes?
No worries—make fresh mashed potatoes, omit milk for firmer texture, and let them chill completely before shaping to avoid stickiness.
- → Are gluten-free versions possible?
Absolutely. Use a 1:1 gluten-free flour blend and gluten-free breadcrumbs to maintain crispiness and structure.
- → Why did my puffs turn out dense?
Overmixing the dough or using warm potatoes often leads to dense puffs. Mix until just combined and always use chilled mashed potatoes.
- → Can these be cooked in an air fryer?
Yes, air frying at 380°F for about 12 minutes with a shake halfway produces extra crunchy puffs with less oil.
