3-Ingredient Steak With Crispy Parmesan Potatoes

Preparation

1. Step 1

   Place potatoes in a medium pot; add cold water to cover by 1". Season with salt, bring to a boil, and cook until potatoes are fork-tender, 12–15 minutes. Transfer to a rimmed baking sheet; let cool slightly, then lightly crush with your palm.

   Step 2

   Heat 3 Tbsp. oil in a large heavy skillet over medium-high. Reduce heat to medium-low and add half of the potatoes; season with 3/4 tsp. salt. Cook, turning once, until golden brown, 15–20 minutes. Transfer potatoes to a plate. Add 3 Tbsp. oil, 3/4 tsp. salt, and remaining potatoes to pan; cook, turning once, until golden brown, 15–20 minutes. Return all potatoes to pan, sprinkle with cheese, and cook, tossing to coat, until cheese begins to crisp, 1–2 more minutes.

   Step 3

   Meanwhile, heat remaining 2 Tbsp. oil in a large skillet over medium-high. Season steak with salt and pepper and cook, turning occasionally, until deep brown and an instant-read thermometer registers 125°F for medium-rare, about 3 minutes per side.

   Step 4

   Transfer steak to a cutting board. Thinly slice steak against the grain and serve with potatoes alongside.
