Seared Steak With Cipolline Onions And Radicchio

1. 1

   Preheat oven to 350u00b0F. Let steaks sit at room temperature 1 hour (this will help them cook more quickly and evenly).

2. 2

   Meanwhile, toss onions on a rimmed baking sheet with 1 Tbsp. oil; season with salt. Roast, turning halfway through, until deeply caramelized and tender, 25-30 minutes. Keep warm.

3. 3

   Heat a cast-iron or ovenproof skillet over medium-high. Rub steaks with 2 tsp. oil (you want just enough to coat them); season with salt. Cook steaks 25-30 seconds. Turn and cook another 25-30 seconds. Continue process of cooking and turning steaks until both sides are deeply browned and an instant-read thermometer inserted into the thickest part registers 130u00b0F, 8-10 minutes.

4. 4

   Add butter to skillet and cook, tilting pan and spooning melted butter over meat, until steaks look glossy on top. Transfer to a cutting board and let rest 10 minutes before slicing against the grain.

5. 5

   While steaks are resting, toss radicchio and vinegar in a large bowl to combine. Drizzle with oil and season with salt; toss to coat.

6. 6

   Serve steak with onions and radicchio.
