Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Trim beef sirloin of excess fat and cut into 1-inch strips.
  2. Step 2: Cut zucchini and broccoli into 1-inch florets. Toss with 2 tbsp olive oil, sea salt, and black pepper in a large bowl.
  3. Step 3: Heat 1 tbsp olive oil in a large oven-safe skillet over medium-high heat. Sear beef strips for 2 minutes per side until browned, then transfer to a plate.
  4. Step 4: Add zucchini and broccoli to the skillet, spreading in a single layer. Scatter garlic and rosemary over vegetables, then drizzle with remaining 1 tbsp olive oil.
  5. Step 5: Return beef to the skillet, nestling it among vegetables. Roast for 15-18 minutes until beef reaches 135°F (57°C) and vegetables are tender-crisp.
