01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper if desired.
02 - Arrange the broccolini on a baking sheet. Drizzle with 2 tablespoons olive oil, sprinkle with lemon zest, half the minced garlic, salt, and pepper. Toss to coat evenly. Roast for 18–20 minutes, turning once halfway through, until tender and slightly crispy at the edges.
03 - Remove the broccolini from the oven and drizzle with fresh lemon juice. Set aside.
04 - Pat the steaks dry with paper towels. Season both sides generously with salt and freshly ground black pepper.
05 - In a small bowl, combine the remaining minced garlic, chopped rosemary, and thyme leaves.
06 - Heat 2 tablespoons olive oil in a large skillet over medium-high heat until shimmering. Add the steaks and sear for 3–4 minutes per side for medium-rare, adjusting time for desired doneness.
07 - In the last minute of cooking, add the butter and garlic-herb mixture to the skillet. Tilt the pan and continuously spoon the melted herb butter over the steaks to baste.
08 - Transfer the steaks to a plate, tent loosely with foil, and rest for 5 minutes. Serve alongside the roasted broccolini with lemon wedges.
