01 - Preheat the oven to 425°F.
02 - On a baking sheet, toss broccolini with olive oil, salt, and pepper. Spread in a single layer. Roast for 15-18 minutes, until tender and slightly crispy. Remove from oven, zest the lemon over the broccolini, and toss.
03 - While broccolini roasts, pat steaks dry with paper towels. Season both sides generously with salt and pepper.
04 - Heat olive oil in a large skillet over high heat until just smoking. Add steaks and sear undisturbed for 2-3 minutes on the first side.
05 - Flip steaks. Add butter, garlic, rosemary, and thyme to the pan. Tilt the pan and, using a spoon, baste steaks with the melted butter and aromatics for another 2-3 minutes, or until desired doneness (125°F for medium-rare).
06 - Transfer steaks to a plate, tent loosely with foil, and let rest for 5 minutes.
07 - Serve steaks with roasted broccolini and lemon wedges on the side.
