Crispy Cheese Potato Puffs are my go-to fix for old mashed potatoes hanging out in the fridge. Tossing them in the oven with a pile of cheese makes boring leftovers feel exciting. These little bites always vanish fast at gatherings, and you can count on them to be just as satisfying when you warm them up for an easy lunch or a last-minute side.
I actually first made these for a family movie night because I wanted something quick but a little fun. Well, now every holiday my kids beg for them with the leftovers.
Irresistible Ingredients
- Eggs: Two Crack them in and beat until they're all mixed up. Helps stick everything together. Go for large ones if possible
- Salt: Toss in just a bit to bring out all those flavors. Try your potatoes first and add more if you want
- Sour cream: One third cup Makes the inside rich and smooth. Full-fat gives the best flavor
- Fresh chives: Two tablespoons Bright green bits for color and a sharp taste. Grab the firmest, freshest ones you can find
- Parmesan cheese: Two tablespoons Gives a tangy, nutty layer. Shred it super fine for easy mixing
- All-purpose flour: Quarter cup Builds the structure so the puffs set nicely. You can swap for any gluten-free blend that works for you
- Shredded cheese: One cup Grated cheddar or mozzarella melts great—get a cheese block and shred it yourself for extra flavor
- Mashed potatoes: Three cups Leftover and cold is best—it keeps the puffs firm and crispy
Effortless Directions
- Cool and Serve
- Let them chill a bit in the pan till you can pick them up. Use a little offset spatula or butter knife to lift them out. Tasty with dip or just plain.
- Bake Until Golden
- Put the tray in your already hot oven at four hundred degrees. Let them bake about twenty to twenty five minutes. You want them golden with slightly loose edges—that means crispiness.
- Season and Prepare to Bake
- Give it a try and sprinkle extra salt if you think it needs more. Scoop big spoons into greased muffin cups about three-quarters up so they've got space to expand.
- Fold in the Mashed Potatoes
- Add your mashed spuds to the egg mix gently. Use a spatula—don't overmix, or they'll get gummy. Some chunkiness is perfect.
- Add the Cheeses and Flavor
- Drop in the grated cheese, parmesan, and snipped chives. Stir until the cheese and herbs look even throughout.
- Mix the Wet Ingredients
- Whisk up eggs with sour cream until it looks smooth and blended—no streaks. This gets the mixture super creamy and ready for potatoes.

Never skip parmesan for me—it gives the puffs deeper flavor. Once I baked these after a big Thanksgiving meal, and it was like discovering a hidden treasure in my plain mashed potatoes. Everyone wanted seconds!
Leftover Storage
Just toss extra puffs in a tight container; they'll be good in the fridge three days. They crisp up awesome in the oven or toaster oven next day. Want to keep them longer? Pop on a tray to freeze, then bag them up. You can bake them straight from frozen too!
Easy Ingredient Swaps
Cheeses are totally flexible—Gruyere brings a nutty vibe or grab a lactose-free one if that's your thing. Any good gluten-free flour blend swaps in just fine if you stay away from wheat. Throw in extra herbs or small veggies if you want more color inside.

Enjoy It Your Way
These make a cozy side next to roast chicken or steak. They're also great with a swipe of sour cream, herby yogurt, or spicy sriracha. At birthday parties, I put out ketchup and ranch—kids can't get enough!
