This clever leftover mashed potato recipe transforms yesterday's side dish into today's star attraction. These cheesy potato puffs have become my signature potluck contribution because they disappear within minutes every single time.
I started making these when trying to use up holiday leftovers and now my family deliberately makes extra mashed potatoes just to ensure we can create these cheesy puffs the next day.
Ingredients
- Cold mashed potatoes: essential as they hold their shape better during mixing and baking
- Shredded cheese: provides gooey pockets of flavor choose a good melting variety like cheddar
- All-Purpose flour: helps bind everything together and creates structure
- Parmesan cheese: adds a nutty umami punch that elevates the entire dish
- Fresh chives: bring a mild oniony brightness that cuts through the richness
- Sour cream: adds tanginess and contributes to the fluffy texture
- Eggs: work as the binding agent and help the puffs rise beautifully in the oven
Step-by-Step Instructions
- Prepare Your Oven and Pan:
- Preheat your oven to exactly 400°F ensuring it reaches full temperature before baking. Thoroughly grease each cup of your muffin tin making sure to cover the sides completely to prevent any sticking which can be frustrating when removing the finished puffs.
- Create Your Base Mixture:
- In a large bowl whisk the eggs and sour cream until they form a smooth consistent mixture with no streaks of egg white visible. This creates the creamy foundation for your puffs so take your time with this step about 1 full minute of whisking.
- Add Flavor Components:
- Add the shredded cheese Parmesan and chopped chives to your egg mixture distributing them evenly. The cheese should be at room temperature to incorporate better and the chives should be finely chopped to disperse their flavor throughout.
- Incorporate The Potatoes:
- Gently fold in your cold mashed potatoes using a rubber spatula with a scooping motion from bottom to top. Work just until combined about 10 to 12 folds maintaining some texture rather than creating a completely smooth mixture which would result in dense puffs.
- Fill The Muffin Cups:
- Use an ice cream scoop or large spoon to portion the mixture evenly into your prepared muffin tin filling each cup about three quarters full. Smooth the tops slightly but don't compress the mixture as it needs space to rise and develop its signature puffy texture.
- Bake To Golden Perfection:
- Place the muffin tin in the middle rack of your preheated oven and bake for 20 to 25 minutes watching carefully after the 18minute mark. Look for deeply golden tops that have risen and set. The puffs should feel firm but still have some give when gently pressed.
- Rest And Serve:
- Allow the puffs to cool in the tin for about 5 minutes this brief resting period helps them set up and makes removal easier. Gently loosen the edges with a knife before carefully lifting them out to serve while still warm.

The secret ingredient in my version is always a touch of smoked paprika folded into the mixture. It started as an accidental addition when cooking for my inlaws but turned into such a hit that its now a permanent part of our family recipe.
Storage Solutions
These cheese puffs maintain their quality remarkably well when stored properly. After cooling completely place them in an airtight container lined with paper towels to absorb excess moisture. They'll keep in the refrigerator for up to 4 days. For longer storage freeze the puffs in a single layer on a baking sheet then transfer to a freezer bag once solid. This prevents them from sticking together and allows you to take out just what you need.
Creative Variations
The basic recipe serves as an excellent canvas for endless flavor combinations. Try mixing in crispy bacon bits and scallions for a loaded potato experience. For a sophisticated twist incorporate caramelized onions and Gruyère cheese. Spice lovers can add diced jalapeños and pepper jack cheese. My personal favorite variation includes roasted garlic and rosemary which creates an incredible aroma while baking and pairs beautifully with roasted meats.
Serving Suggestions
While these puffs shine as a standalone appetizer they truly excel as part of a complete meal. Serve them alongside a protein like roasted chicken or grilled steak where they'll replace traditional mashed potatoes with a fun textural twist. For brunch they pair wonderfully with a simple green salad dressed in vinaigrette the acidity balances their richness perfectly. During holiday gatherings place them in a breadbasket as an unexpected alternative to dinner rolls.
