This cheesy mashed potato puffs recipe transforms leftover mashed potatoes into a delightful snack or side. They come out light, fluffy, with melty cheese inside and a golden crust on top. Perfect for a cozy dinner accompaniment or a crowd-pleasing appetizer.
I once made these after a big family dinner with extra mashed potatoes. Everyone kept sneaking puffs before dinner because they smelled so good warm from the oven.
Ingredients
- 2 cups mashed potatoes: cooled for best texture leftover or freshly made both work well
- 2 large eggs: help bind the mixture and add moisture so the puffs hold their shape
- 1 cup shredded cheddar cheese: adds sharp, melty flavor choose a sharp aged cheddar for the best taste
- 1/4 cup grated Parmesan cheese: gives a savory, nutty edge that enhances the cheesiness
- 1/4 cup sour cream: contributes creaminess and a slight tang which keeps the puffs moist
- 2 tablespoons chopped green onions: optional for fresh brightness and mild onion flavor
- 1/2 teaspoon garlic powder: adds subtle warmth without overpowering
- 1/2 teaspoon salt: balances the flavors do not skip this or the puffs will taste flat
- 1/4 teaspoon black pepper: for gentle heat and depth
- 1/2 teaspoon baking powder: makes the puffs rise slightly for a lighter texture
Instructions
- Build The Batter:
- In a large bowl, combine the cooled mashed potatoes with eggs, cheddar cheese, Parmesan, sour cream, and green onions if using. Stir gently until the mixture is smooth and evenly combined. This ensures even baking and cheesy pockets inside.
- Add Seasonings And Leavening:
- Sprinkle in garlic powder, salt, black pepper, and baking powder. Mix thoroughly so the baking powder distributes evenly. This is key to giving the puffs a light airy texture instead of dense heaviness.
- Prepare The Muffin Tin:
- Preheat your oven to 400 degrees Fahrenheit or 200 degrees Celsius. Lightly grease a 12-cup muffin tin or line each cup with paper liners for easy removal and less mess.
- Fill And Bake:
- Scoop the batter into the muffin cups filling each about three quarters full. This gives room for the puffs to rise and crisp on top. Place in the oven and bake for twenty to twenty five minutes until the tops turn golden and have a slight crisp.
- Cool And Serve:
- Remove the puffs from the oven and allow them to cool for about five minutes in the pan before carefully removing. Serve warm alongside sour cream, ranch dressing, or your favorite dipping sauce.

My favorite ingredient is the Parmesan cheese because even a little adds a sophisticated depth. When I first shared these at a potluck my aunt said they reminded her of something her mother used to make, which made the moment feel extra special.
Storage Tips
Store leftover puffs in an airtight container in the refrigerator for up to three days. Reheat in an oven or toaster oven at 350 degrees Fahrenheit for about ten minutes to bring back the crispiness. Avoid microwaving if you want to keep the edges crisp.
Ingredient Swaps
For a dairy-free version substitute sour cream with plain coconut yogurt and choose dairy-free cheese alternatives. You can swap cheddar for any sharp melting cheese such as gruyere or monterey jack for a different twist. If you like a bit of spice, mix in finely diced jalapeños along with the green onions.
Serving Ideas
These puffs are perfect beside a bowl of soup or a fresh green salad for a quick lunch. They also work as finger food with cocktail parties or family movie nights. A dollop of sour cream or a tangy dip like salsa or tzatziki complements the cheesy richness well.

This recipe is a perfect way to turn leftovers into a delicious treat that everyone will love. Enjoy the cheesy goodness and the happy moments it brings.
