Ingredients You’ll Need
The beauty of Cheesy Mashed Potato Puffs lies in their simplicity—each ingredient is easy to find and plays a deliciously important part. These humble staples come together to create a snack that’s packed with flavor, color, and irresistible texture.
- Mashed potatoes: Cold, leftover mashed potatoes work best for structure and easy mixing.
- Large eggs: These bind everything together and help the puffs rise and hold their shape.
- Shredded cheddar cheese: Melts into gooey, golden pockets while adding sharp, cheesy flavor.
- Grated Parmesan cheese: Brings a salty, nutty punch and helps create a crispy top.
- Sour cream: Adds tang and keeps the puffs moist and creamy inside.
- Chopped fresh chives or green onions: Lend fresh color, a mild oniony bite, and a pop of green.
- Garlic powder: Infuses gentle savory depth without overpowering the other flavors.
- Salt: Enhances all the flavors—taste your potatoes and adjust if they’re already salted!
- Black pepper: Adds a subtle warmth and balances the cheesy richness.
- Olive oil spray: Prevents sticking so your puffs pop right out of the muffin tin with crispy edges.
How to Make Cheesy Mashed Potato Puffs
Step 1: Prep Your Muffin Tin
Start by preheating your oven to 400°F (200°C). Lightly grease or spray a 12-cup muffin tin with olive oil. This quick step ensures your Cheesy Mashed Potato Puffs release easily after baking and develop those irresistible golden edges.
Step 2: Mix the Batter
In a large bowl, combine your cold mashed potatoes, eggs, shredded cheddar, Parmesan, sour cream, chives or green onions, garlic powder, salt, and black pepper. Stir everything together until the mixture is smooth and uniform. Don’t overmix—just enough to combine, so you keep the puffs light and fluffy inside.
Step 3: Fill the Muffin Tin
Spoon the mixture into your prepared muffin cups, filling each one almost to the top. If you love extra cheesiness (and who doesn’t?), sprinkle a little more cheddar or Parmesan over each mound. This creates a bubbling, golden lid as they bake.
Step 4: Bake to Golden Perfection
Pop the muffin tin into your preheated oven and bake for 25 to 30 minutes. You’ll know your Cheesy Mashed Potato Puffs are ready when they’re deep golden brown on top and slightly crispy around the edges. Let them cool in the pan for 5 minutes to set, then gently lift each puff out with a spoon.
How to Serve Cheesy Mashed Potato Puffs

Garnishes
For the perfect finishing touch, sprinkle your Cheesy Mashed Potato Puffs with extra chopped chives, a dusting of Parmesan, or even a tiny dollop of sour cream. These simple garnishes add color, flavor, and a little restaurant-worthy flair to every bite.
Side Dishes
Pair these puffs alongside roasted meats, grilled veggies, or a crisp salad for a meal that hits every craving. They’re a fantastic match with barbecue, chicken, or a bowl of homemade soup. No matter the main, Cheesy Mashed Potato Puffs round out the plate beautifully.
Creative Ways to Present
Serve them as party appetizers on a platter with toothpicks, tuck them into lunchboxes for a fun surprise, or stack them high for a brunch buffet. Try mini versions in a mini muffin tin for bite-sized treats, or layer them with cooked bacon crumbles for an extra-indulgent twist.
Make Ahead and Storage
Storing Leftovers
Leftover Cheesy Mashed Potato Puffs keep beautifully! Store any extras in an airtight container in the fridge for up to 3 days. They’re just as delicious the next day—maybe even better as the flavors mingle.
Freezing
To freeze, let the puffs cool completely, then arrange them in a single layer on a baking sheet and freeze until solid. Once frozen, transfer to a zip-top bag or airtight container. They’ll keep for up to one month—just thaw and reheat when you need a cheesy snack fix!
Reheating
For best results, reheat Cheesy Mashed Potato Puffs in the oven or air fryer at 350°F until hot and crisped up—about 8 to 10 minutes. The microwave works in a pinch, but you’ll miss out on that signature crispy exterior.
FAQs
Can I use instant mashed potatoes instead of homemade?
Absolutely! Instant mashed potatoes will work in a pinch; just make them on the thicker side and let them chill before using. The texture will still yield fluffy, delicious Cheesy Mashed Potato Puffs.
What cheeses can I substitute for cheddar?
Feel free to swap in mozzarella for extra stretch or pepper jack for a little kick. Any good melting cheese will bring its own personality to your puffs, so have fun trying different combos!
Do I have to use a muffin tin?
While a muffin tin gives the puffs their perfect shape and crispy edges, you can also dollop the mixture onto a lined baking sheet. Just keep an eye on the bake time, as they may cook a little faster.
Can these be made ahead for a party?
Yes! Bake them a day in advance, store in the fridge, and reheat in the oven right before serving. They’ll be hot, crispy, and ready to delight your guests in minutes.
Are Cheesy Mashed Potato Puffs gluten free?
They sure are! The recipe contains no flour or breadcrumbs, making Cheesy Mashed Potato Puffs a naturally gluten-free treat (just double-check your cheese and sour cream labels, if needed).
