Servings and timing

Serves about 4 people.
Prep time: ~30 minutes plus chilling time.
Cook time: ~15–20 minutes.
Chilling time: ~1 hour (helps the mash firm up for cutting).

Variations

Cheesy: Mix shredded cheddar or Parmesan into the mashed potatoes before chilling for extra flavor.
Herb‑infused: Add fresh parsley, oregano, or garlic powder to the mash for enhanced seasoning.
Spicy: Stir in a pinch of cayenne or chili flakes for a kick.
Oven/air fry option: Instead of deep‑frying, brush with oil and bake at high heat or air fry until crisp.

Storage/Reheating

Store leftover fries in the refrigerator in an airtight container for 2–3 days. To reheat, spread on a baking sheet and bake or air fry to restore crispiness. Avoid microwaving, which can make them soggy.

FAQs

What type of potatoes are best for these fries?

Can I use leftover mashed potatoes?

Yes, leftover mashed potatoes can be used, though you may need to adjust flour or starch to help them hold together.

How do I keep the fries from falling apart?

Chilling the mashed potato layer until firm before cutting helps them hold their shape during frying.

Can I make these gluten‑free?

Yes. Use gluten‑free flour and breadcrumbs in place of regular to make them gluten‑free.

What dipping sauces go well with these fries?

Classic ketchup, garlic aioli, chipotle sauce, or ranch are all great choices.

Can I prepare these ahead of time?

You can shape and coat the fries ahead of time and refrigerate or freeze before frying.

How do I reheat leftovers to keep them crispy?

Reheat in the oven or air fryer rather than the microwave to restore crispiness.

Can I add cheese inside the fries?
