Can I make these potato balls ahead of time?
Yes. Form and refrigerate uncooked balls for up to 4 hours, or freeze for up to 2 weeks. Fry from frozen or thawed; add 1–2 minutes if frying from frozen.
What oil temperature should I use for frying?
Heat vegetable oil to 350°F. Use a thermometer for consistent results; oil that's too cool produces greasy balls, while oil that's too hot burns the outside before the inside heats through.
How do I know when the potato balls are done?
They should be golden brown on all sides and float steadily in the oil. Internal temperature should reach 165°F if using a probe thermometer.
Can I use leftover mashed potatoes?
Yes. Use about 2 cups leftover mashed potatoes. They should be plain or lightly seasoned; skip additional salt to avoid over-seasoning.
What dipping sauces pair well with these?
Sour cream, ranch dressing, marinara sauce, and aioli all complement the savory cheese and potato flavor.
