Crispy Smashed Cacio e Pepe Potatoes Step-by-step instructions

Before you start

Before beginning, ensure all ingredients are measured and ready. The Pecorino Romano should be finely grated to ensure quick and even melting. Preheat your oven to 450°F (230°C) well in advance, as the high heat is essential for achieving the necessary crispness.

Have a heavy cast-iron skillet ready, and if you are using a masher, ensure it is clean and dry. A clear workspace is important for the smashing step, which can be done efficiently with a heavy-bottomed glass or a traditional potato masher.

Instructions

Boiling and Drying

1. 1Boil the Potatoes
   Place the baby Yukon Gold potatoes in a large pot of salted water. Bring to a boil and cook until the potatoes are fork-tender throughout. Drain the potatoes thoroughly and allow them to steam-dry in the colander for a few minutes to ensure maximum crispiness during roasting.
   Look for The potatoes should be soft enough to be easily pierced by a fork without falling apart.
   Tip Ensure the potatoes are completely dry before smashing to prevent steaming in the oven.

The potatoes should be soft enough to yield easily when pressed with a fork. After draining, they must look matte and dry, with no visible water droplets remaining on the skin. This drying phase is critical for the final texture, as any residual moisture will inhibit the crisping process in the oven.

Smashing and Roasting

2. 2Smash and Roast
   Preheat the oven to 450°F (230°C). Pour the extra-virgin olive oil into a preheated cast-iron skillet. Place the boiled potatoes into the skillet and use a masher to smash each one until flat with jagged edges. Roast in the oven for 25 minutes until the edges are golden and ultra-crisp.
   Look for Look for deep golden brown edges and a crisp, jagged exterior texture on the potatoes.
   Tip Using a cast-iron skillet helps achieve a superior crust compared to lighter baking sheets.

The smashed potatoes should look like rustic, flat discs with plenty of jagged edges. When roasting, listen for the sound of the oil sizzling in the skillet. The potatoes should be deep golden brown, and the edges should look brittle and crunchy, indicating that they have achieved the desired level of crispness before the butter and cheese are added.

Finishing the Dish

3. 3Finish with Pepper Butter and Cheese
   While the potatoes roast, melt the butter in a small saucepan and toast the cracked black peppercorns until fragrant. Remove the skillet from the oven, pour the foaming pepper butter over the crispy potatoes, and toss to coat. Blanket with the grated Pecorino Romano and return to the oven for 3 minutes to melt and blister the cheese.
   Look for The cheese should be melted and lightly blistered, creating a savory, crusty layer on top.
   Tip Grate the Pecorino finely to ensure it melts evenly over the hot potatoes.

After adding the pepper butter and cheese, the potatoes should be aromatic and visually appealing. The melted Pecorino should create a cohesive, slightly browned layer that clings to the crispy potato edges.

The final result should be a harmonious blend of textures, with a crunchy exterior, a soft center, and a savory, melted cheese and pepper finish.

Common mistakes

A common error is failing to dry the potatoes thoroughly after boiling; excess moisture will cause them to steam rather than crisp, leading to a soft, mushy texture. Do not overcrowd the skillet, as this prevents the potatoes from getting enough contact with the hot surface to develop a proper crust.

Additionally, avoid using pre-grated cheese, which often contains anti-caking agents that hinder the smooth melting required for the characteristic Cacio e Pepe coating.

How to tell it’s done

The potatoes are ready when they have reached a deep, dark golden-brown color and the edges are brittle and crisp to the touch. The Pecorino Romano topping should be fully melted and exhibit small, golden-brown blisters, signaling that the cheese has toasted slightly.

Because this dish does not contain raw proteins, you do not need to check for internal temperatures; rely instead on the visual cues of a crispy, jagged exterior and the inviting, aromatic scent of toasted black pepper and melted, browned cheese.
