How to Make Leftover Mashed Potato Cheese Puffs
Follow these straightforward steps to create crispy, cheesy puffs your whole family will enjoy.
- Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or a silicone mat for easy cleanup.
- In a large bowl, combine the leftover mashed potatoes, shredded cheddar cheese, flour, egg, garlic powder, onion powder, salt, pepper, and chopped green onions. Mix until everything is well incorporated and the mixture is slightly sticky but firm enough to shape.
- Using a tablespoon or small cookie scoop, form the mixture into bite-sized balls and place them on a plate.
- Brush each ball lightly with melted butter, then roll them in panko breadcrumbs until fully coated for a crispy outer layer.
- Arrange the coated puffs evenly on the prepared baking sheet, spacing them about an inch apart.
- Bake for 12 to 15 minutes, turning halfway through, until the cheese puffs are golden brown and crispy on the outside.
- Remove from the oven and let them cool for 3-5 minutes before serving to allow the cheese to set slightly.
The mashed potato cheese puffs are perfectly done when they have a golden, crunchy exterior and a warm, gooey center with melted cheese. They should hold their shape but be soft inside, with a satisfying crisp bite.
Tips for the Best Results
Here are some tips to ensure your mashed potato cheese puffs come out perfect every time.
- Use leftover mashed potatoes that are chilled or at room temperature for easier shaping.
- If the mixture feels too wet, add a little more flour to help it bind better.
- Coat the puffs generously with panko breadcrumbs for maximum crispiness.
- Don’t overcrowd the baking sheet; give each puff room to crisp evenly.
- Experiment with different cheeses or add spices like smoked paprika or cayenne for a flavor twist.
Serving Suggestions
Serve these mashed potato cheese puffs as a tasty appetizer with a side of sour cream or your favorite dipping sauce like ranch or spicy aioli. They also pair beautifully with a fresh green salad or roasted vegetables for a light meal.
They’re perfect for casual occasions like family movie nights, game days, or weekend brunches. For drinks, try pairing them with a crisp white wine, a cold beer, or even a refreshing iced tea.
Storage and Reheating
You can store leftover mashed potato cheese puffs in an airtight container in the refrigerator for up to 3 days. Reheat them in the oven at 350°F for about 8-10 minutes to restore crispiness.
For longer storage, freeze the cheese puffs on a baking sheet until solid, then transfer to a freezer-safe bag or container. Reheat from frozen in a preheated oven at 375°F for 15-20 minutes until warmed through and crispy.
Frequently Asked Questions
Can I use fresh mashed potatoes instead of leftovers?
Yes, you can use freshly made mashed potatoes, but make sure they are cooled completely before mixing. Warm mashed potatoes may cause the mixture to be too soft and difficult to shape.
What if I don’t have panko breadcrumbs?
You can substitute regular breadcrumbs, crushed crackers, or even crushed cornflakes to coat the cheese puffs. Panko gives the crispiest texture, but alternatives work fine in a pinch.
Can I make these cheese puffs dairy-free?
Yes, substitute the cheddar cheese with a plant-based cheese and use a dairy-free butter alternative for coating. Just keep in mind the texture and flavor will be slightly different but still delicious.
Are these cheese puffs suitable for freezing?
Absolutely! They freeze well and can be reheated straight from the freezer. Just bake a little longer when reheating to ensure they’re heated through and crispy on the outside.
