These mashed potato cheese puffs have saved me on countless busy nights when I needed a quick snack or wanted to make use of leftover mashed potatoes in a fun way. With their creamy center and crispy edges, they make any leftover feel like something new and special.
I first made these after a big holiday dinner when the mashed potatoes were taking up space in the fridge and now I look forward to leftovers just for this recipe.
Ingredients
- Mashed potatoes chilled: Make sure your mashed potatoes are firm from the fridge for best texture
- Shredded cheese: Cheddar mozzarella or any good melting cheese for gooey richness Try to use freshly shredded cheese for maximum melt and flavor
- All-purpose flour: Helps bind the puffs together Use a fresh bag for best results
- Parmesan cheese: Optional but adds a salty savory punch Look for a wedge of Parmesan and grate it yourself if possible
- Fresh chives: Brings freshness and a mild onion flavor Go for bright green chives without any wilt
- Sour cream: Adds tang and moisture Choose full fat for extra creaminess
- Salt to taste: Just enough to bring out the flavors Taste your mashed potatoes first to judge if more is needed
- Eggs beaten: Work as a binder for the whole mixture Use large fresh eggs for best puff
Step-by-Step Instructions
- Preheat the Oven:
- Set your oven to 400 degrees F or 200 degrees C and grease your muffin tin well so the puffs release easily after baking
- Mix the Wet Ingredients:
- In a large bowl whisk the eggs and sour cream until light and smooth This helps keep your potato puffs fluffy inside
- Combine Cheese and Chives:
- Add the shredded cheese Parmesan and chives to the bowl and gently stir making sure everything is evenly mixed for every bite to be cheesy and flavorful
- Fold in the Mashed Potatoes:
- Carefully add in your cold mashed potatoes mixing gently so the mixture stays light but well combined Do not overwork or the puffs may be dense
- Fill the Muffin Pan:
- Portion the potato mixture into the greased muffin tin cups filling each about three quarters full to allow room for them to puff up in the oven
- Bake Until Golden:
- Place the pan on the middle rack and bake for about twenty to twenty five minutes until the tops are richly golden and puffed up checking at the twenty minute mark for doneness
- Cool and Serve:
- Let the puffs cool for a few minutes before gently lifting out with a spoon and serving warm with your favorite dip

I love chives in these puffs the pop of green and gentle onion flavor remind me of the fresh herbs my grandmother would snip from her backyard Our family always saves a spoonful of chives just for this recipe
