01 - Preheat oven to 425°F (220°C).
02 - Toss the broccolini with 1 tablespoon olive oil, half the minced garlic, a pinch of salt, and pepper. Spread in an even layer on a baking sheet and roast for 15–18 minutes until crisp-tender with light charring.
03 - While the broccolini roasts, pat the steaks dry with paper towels and season both sides generously with kosher salt and freshly ground black pepper.
04 - Heat 1 tablespoon 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. For thicker cuts, reduce heat to medium and cook an additional 1–2 minutes per side.
05 - During the last minute of cooking, add the butter, remaining garlic, thyme, and rosemary to the pan. Tilt the skillet and baste the steaks repeatedly with the melted herb butter.
06 - Transfer steaks to a cutting board and let rest for 5 minutes to allow juices to redistribute.
07 - Arrange the rested steaks and roasted broccolini on plates. Sprinkle the broccolini with lemon zest and chopped parsley, then squeeze fresh lemon juice over the top. Serve with additional lemon wedges on the side.
