What You'll Need
The equipment is wonderfully simple.
- 12-cup muffin pan
- Mixing bowl
- Measuring cups and spoons
- Wooden spoon or rubber spatula
- Cheese grater
- Ice cream scoop or spoon
A standard muffin pan works perfectly for these.
Ingredient Additions and Substitutions
This recipe is very forgiving, so don't be afraid to make it your own.
Change the Cheese
Try:
- Sharp cheddar
- Mild cheddar
- Monterey Jack
- Pepper Jack
- Gruyère
- Mozzarella
- Parmesan
A mixture of cheddar and Parmesan is especially delicious.
Add Bacon
Cooked, crumbled bacon makes these potato puffs even more irresistible.
Fold about 1/2 cup into the mixture.
Add Ham
Diced cooked ham is another wonderful option, especially if you're making these after a holiday meal.
Add Vegetables
Finely chopped cooked broccoli, spinach, roasted peppers, or green onions can add extra flavor and color.
Just avoid adding vegetables that contain lots of excess moisture, since they can make the puffs softer.
Make Them Spicy
Add a pinch of cayenne, a little smoked paprika, or some finely chopped jalapeño.
Pepper Jack cheese works beautifully here too.
How to Make Cheesy Mashed Potato Puffs
Step 1: Preheat the Oven
Preheat your oven to 400°F.
Grease a standard 12-cup muffin pan generously with cooking spray or butter.
Don't skip the greasing step!
Cheesy potatoes have a habit of wanting to stick to the pan.
Step 2: Prepare the Potato Mixture
Add the mashed potatoes to a large mixing bowl.
Stir in the shredded cheddar, Parmesan, eggs, sour cream, green onions, garlic powder, onion powder, black pepper, and parsley if using.
Mix until everything is evenly combined.
The mixture should be thick and scoopable.
Step 3: Fill the Muffin Cups
Divide the potato mixture evenly among the prepared muffin cups.
Fill each cup nearly to the top.
There's no need to smooth them perfectly. Those little uneven edges can become deliciously golden in the oven.
Step 4: Add a Little Extra Cheese
If you're a serious cheese lover—and I absolutely understand if you are—sprinkle a little extra shredded cheddar or Parmesan over the tops.
It creates an irresistible golden cheesy crust.
Step 5: Bake
Place the muffin pan in the preheated oven.
Bake for approximately 20–25 minutes, or until the potato puffs are heated through and the tops are golden brown.
If you want extra color on top, you can place them under the broiler for a minute or two at the end.
Just watch them closely!
Cheese can go from beautifully golden to very brown in a hurry.
Step 6: Let Them Rest
Remove the pan from the oven and allow the puffs to cool for about 5 minutes.
Run a butter knife gently around the edges if necessary, then carefully lift them from the pan.
Serve warm.
And don't be surprised if you need to make a second batch.
Tips for Making Perfect Potato Puffs
Use Cold Leftover Mashed Potatoes
Cold mashed potatoes are actually easier to work with because they're firm.
If your potatoes are freshly made and very hot or loose, allow them to cool before mixing.
Don't Make the Mixture Too Wet
Mashed potatoes vary quite a bit.
Some are thick and fluffy, while others contain lots of milk, cream, or butter.
If your potato mixture seems unusually loose, you can add a little extra shredded cheese or a tablespoon of breadcrumbs to help firm it up.
Grease the Pan Well
This is one of the most important tricks.
The combination of cheese and potatoes can stick.
A generous coating of cooking spray or butter makes removal much easier.
Don't Overbake
You want the tops golden and the centers soft.
Overbaking can dry out the potatoes.
Let Them Rest Before Removing
Give them those five minutes after baking.
They'll firm up slightly and become easier to remove without falling apart.
What to Serve With Cheesy Mashed Potato Puffs
These little bites can go with almost anything.
Serve them alongside:
- Roast chicken
- Turkey
- Meatloaf
- Roast beef
- Pork chops
- Grilled steak
- Baked ham
- Sausage
- Green beans
- Roasted vegetables
- A fresh salad
For a holiday meal, they make a fun alternative to ordinary mashed potatoes.
For breakfast, serve them with scrambled eggs and crispy bacon.
And for an appetizer?
Put out a platter with sour cream, ranch dressing, or a creamy herb dip for dunking.
Can You Make Mashed Potato Puffs Ahead of Time?
Yes!
You can assemble the potato mixture and refrigerate it before baking.
Cover the bowl tightly and refrigerate for up to about 24 hours.
When you're ready to bake, scoop the mixture into the greased muffin pan and bake as directed.
If the mixture is very cold, it may need a few extra minutes in the oven.
How to Store Leftover Potato Puffs
Store cooled potato puffs in an airtight container in the refrigerator.
They should keep for about 3–4 days when properly refrigerated.
To reheat, use the oven, toaster oven, or air fryer for the best texture.
Microwaving works too, although the outside won't stay as crisp.
Can You Freeze Cheesy Mashed Potato Puffs?
Yes!
Allow the baked puffs to cool completely, then arrange them in a single layer on a baking sheet and freeze until firm.
Transfer them to a freezer-safe bag or container.
For best quality, use them within about 2–3 months.
Reheat from frozen in a 375°F oven or air fryer until hot throughout.
Frequently Asked Questions
Can I use instant mashed potatoes?
You can, although homemade leftover mashed potatoes generally provide better flavor and texture.
If using instant potatoes, make sure they're thick rather than very loose.
Why are my potato puffs falling apart?
The mixture may be too wet, or they may need a little more time to set.
Allowing them to cool for several minutes after baking also helps them firm up.
Can I make these without Parmesan?
Absolutely.
Simply replace the Parmesan with additional cheddar or another cheese you enjoy.
Can I use sweet potatoes?
Yes! Sweet potato puffs can be delicious.
Because sweet potatoes have a naturally sweeter flavor, consider adding a little less savory seasoning and experimenting with Parmesan, cheddar, or even a touch of smoked paprika.
Can I add bacon?
Definitely.
Cook and crumble the bacon first, then stir it into the potato mixture before baking.
Can I make these in a mini muffin pan?
Yes.
Mini potato puffs are especially nice for parties and appetizers.
Because they're smaller, start checking them earlier and adjust the baking time as needed.
How do I keep the potato puffs from sticking?
Grease the muffin pan generously with butter or cooking spray.
A nonstick muffin pan can also make removal easier.
