Crispy Smashed Potatoes with Truffle Parmesan Fondue

Imagine a cast iron skillet filled with golden, craggy smashed potatoes, their edges fried to a shattering crisp in foaming garlic-rosemary butter. Then comes a molten avalanche of gruyere and parmesan, laced with truffle oil, poured right over the top.

Every bite is a study in contrast: the crunch of the potato, the stretch of the cheese, the earthy perfume of truffle. This is the appetizer that steals the show—simple enough for a weeknight, luxurious enough for a dinner party. Get ready to dip, pull, and devour.

This recipe transforms humble potatoes into a showstopping skillet of crispy, buttery, cheesy goodness. The potatoes are boiled until tender, smashed to create maximum surface area, then fried in fragrant garlic-rosemary butter until every jagged edge is golden and crunchy.

Meanwhile, a velvety fondue of aged gruyere, parmesan, and truffle oil comes together in minutes. Pour it over the hot potatoes, scatter with chives, and serve straight from the pan. It's the kind of dish that invites communal dipping and happy, messy fingers.

Ingredients

Why this recipe works

Boiling the potatoes first ensures they are fully tender inside, so after smashing and frying, they develop a crisp exterior while staying fluffy within.

The smashing step is key—it creates thin, uneven edges that crisp up beautifully in the hot butter, giving you a maximum crunch-to-cream ratio in every bite. Frying in foaming butter with garlic and rosemary infuses the potatoes with aromatic flavor that complements the rich cheese fondue.

The fondue relies on the classic combination of gruyere and parmesan, which melt into a smooth, stretchy sauce when heated gently with cream. Gruyere brings nutty, alpine notes, while parmesan adds savory depth.

A touch of truffle oil elevates the whole dish with an earthy, luxurious aroma. Pouring the fondue over the potatoes just before serving keeps the cheese molten and dippable, making every bite a perfect harmony of crispy, creamy, and indulgent.

Notes and substitutions

Choose golden or Yukon Gold potatoes for their buttery flavor and ability to hold their shape when smashed. Avoid waxy red potatoes, which can become gummy, and starchy russets, which fall apart too easily. Smash the potatoes gently—you want large, craggy pieces, not mush. The uneven edges are what crisp up so beautifully in the butter.

For the fondue, grate the cheeses fresh from a block; pre-shredded cheese contains anti-caking agents that can make the sauce grainy. Use a good-quality aged gruyere for the best flavor. Truffle oil is potent—start with a small amount and add more to taste. If you don't have truffle oil, the fondue is still delicious without it, but the truffle adds that special touch that makes this dish memorable.

• aged alpine gruyere: Swiss cheese or fontina for a similar nutty, melty texture.
• golden potatoes: Yukon Gold or red potatoes work well; avoid russets as they fall apart.
• truffle oil: Omit for a non-truffle version, or use a few drops of truffle-infused honey.
• fresh rosemary: Dried rosemary (use 1 tbsp) or fresh thyme for a different herb note.
