Crispy Potato Poppers

Featured in Appetizers & Snacks.

These crunchy potato poppers are a fantastic way to turn leftover mashed potatoes into golden bites in 20 minutes. Just blend mashed potatoes with cornstarch, give them your favorite seasonings, and cook them in an air fryer until crisp. You can get creative with coatings like breadcrumbs or seeds for extra crunch. They're awesome paired with dipping sauces and work as a snack or a side. No air fryer? Use your oven to bake them instead!

Turning day-old mashed potatoes into crunchy, irresistible potato balls is pure kitchen magic that makes basic leftovers totally mouthwatering. These snackable treats form an amazingly crunchy shell while keeping a soft, velvety middle - you'll grab one after another. I've started purposely making too many mashed potatoes during dinner just so I can whip up these tempting little morsels the next day.

Just yesterday, I used leftover buttery mashed potatoes from our family meal. My little girl helped roll them into shapes, and seeing her excitement when they turned golden in the air fryer showed me how the simplest cooking brings the biggest joy.

Key Ingredients

  • Mashed Potatoes: Refrigerated leftover mashed potatoes shape much better. If you're making fresh ones, cool them totally first.
  • Cornstarch: This secret ingredient gives you that amazing crunch factor. Pick a decent brand for best outcomes.
  • Cooking Spray: Go with a mild-flavored oil spray for complete coverage. Don't use butter sprays as they might burn.
  • Optional Seasonings: Try adding chopped herbs, a dash of garlic powder, or some smoked paprika for extra taste.
  • Salt and Pepper: Even when your mashed potatoes already have seasoning, a bit more really brings out their flavor.

Step-by-Step Cooking Guide

Getting Your Potatoes Ready
Begin with chilled mashed potatoes for easier handling. Mix in cornstarch bit by bit until the mix feels sturdy. Check by making a small ball - it shouldn't stick to your hands. Let it sit for 5 minutes so the cornstarch blends in fully. Add more seasoning if needed, but remember the flavors get stronger when cooked.
Making The Balls
Grab a small cookie scoop or spoon for even sizes. Roll between your hands to make nice round balls. Put them on a tray lined with parchment. If they get sticky, lightly dust your hands with cornstarch. Try to make them about 1-inch across for perfect cooking.
Using An Air Fryer
Heat your air fryer to 400°F. Put the potato balls in with some room between them. Spray them well with cooking oil from every side. Cook them for 8 minutes, then gently move the basket. Keep cooking another 7-12 minutes until they look golden. Do smaller batches so they don't crowd each other.
Oven Method
Heat your oven to 425°F. Place the balls on a lined baking tray. Spray them thoroughly with cooking oil. Bake them for 20-25 minutes, turning them over halfway. Watch them closely at the end so they don't burn.
Getting Ready To Serve
Let them cool for 2-3 minutes before eating. Arrange them nicely with different dipping sauces. Add some fresh herbs on top if you want. Serve them right away while they're still crunchy.

When I was younger, my grandma always found clever ways to use up leftovers. These potato balls remind me of how she could take ordinary ingredients and make something everyone loved.

Heat Management

Getting that perfect crunch outside means keeping the heat steady. In your air fryer, don't pack too many in at once and keep an eye on the first batch since every air fryer cooks a little differently.

Getting The Right Feel

The cornstarch doesn't just hold everything together - it creates that amazing crunchy exterior. If your mashed potatoes seem too wet, you might need to add extra cornstarch. You want them firm enough to keep their shape but not dry.

Plan Ahead Options

You can form your balls up to a day before and keep them in the fridge. Just take them out about 15 minutes before cooking so they aren't too cold when they hit the air fryer.

These potato balls have become my favorite way to save leftover mashed potatoes, turning what might get thrown out into something everybody fights over. Served as a snack or next to a main dish, they vanish in minutes, showing that sometimes the easiest recipes turn out the tastiest.

→ Main Ingredients

01 Cooking spray
02 5 tablespoons arrowroot powder or cornstarch
03 2 cups mashed potatoes (fresh or leftovers)

Instructions

Step 01

Toss the mashed potatoes into a bowl with the arrowroot or cornstarch. Stir until it turns into a dough that’s firm, easy to shape, and kinda like thick gnocchi dough. Need extra flour or starch? Sprinkle some in!

Step 02

With clean hands, mold the mixture into little balls—go for something just a tad smaller than a golf ball.

Step 03

Place the balls in your air fryer basket, giving them a generous spritz of oil. Cook them at 450°F for about 15–20 minutes, until they have a crispy golden shell.

Notes

  1. Tastes great with vegan green goddess dip, ketchup, or aioli
  2. If you don’t have cornstarch or arrowroot, go ahead and swap in flour
  3. Roll them in breadcrumbs, seeds, or cornmeal before cooking for extra texture
  4. Spice it up before making your dough—add seasoning
