01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Place green beans on the prepared baking sheet. Drizzle with olive oil, sprinkle with salt, pepper, garlic powder, and oregano. Toss until evenly coated and arrange in a single layer.
03 - Roast green beans for 18 to 20 minutes, tossing halfway through, until tender and lightly caramelized.
04 - While green beans roast, pat steaks dry with paper towels. Season both sides of steaks with kosher salt and freshly ground black pepper.
05 - Heat olive oil in a large skillet over medium-high heat until hot but not smoking. Add steaks and sear undisturbed for 3 to 4 minutes per side for medium-rare, adjusting cook time as needed for preferred doneness.
06 - In the last 2 minutes of cooking, add butter, minced garlic, rosemary, and thyme to the pan. Tilt skillet and continuously spoon melted herb butter over the steaks until fragrant.
07 - Transfer steaks to a plate, loosely cover with foil, and allow to rest for 5 minutes.
08 - Plate steaks, spooning pan juices over the top, and serve alongside roasted green beans.
