- 1 8-ounce boneless New York strip steak
- Kosher salt, freshly ground pepper
- 1 tablespoon olive oil, plus more for drizzling
- 1 sprig rosemary
- 2 garlic cloves, unpeeled
- Flaky sea salt
- Coarsely chop steak into 1/4″ pieces, including fat but removing any gristle.
- Transfer to a small bowl; season with kosher salt and pepper and toss to combine. Form into a 3 1/2″-diameter patty about 1″ thick. Season top and bottom generously with kosher salt and pepper.
- Heat a dry medium skillet, preferably cast-iron, over medium. Cook patty undisturbed until a nicely seared brown crust forms, about 3 minutes. Turn patty and add 1 Tbsp. oil, then rosemary sprig and garlic cloves to skillet. Cook, turning garlic occasionally to keep it from burning, until second side of patty is nicely browned, about 3 minutes (inside will still be fairly pink).
- Transfer steak to a plate and top with rosemary and garlic; sprinkle with sea salt and drizzle with oil.
