Pat the sirloin steak dry with paper towels and cut into 1-inch cubes.
Season the steak cubes evenly with the sea salt and black pepper.
Heat a large cast-iron skillet over medium-high heat and add the ghee.
Once the ghee is shimmering, add the steak bites in a single layer, ensuring they are not crowded to allow for proper browning.
Sear the steak for 2 minutes without moving them to develop a golden-brown crust, then flip and cook for another 2 minutes.
Lower the heat to medium and add the minced garlic, rosemary, and thyme to the skillet.
Toss the steak bites in the garlic herb butter for 1 minute until fragrant and well-coated.
While the steak rests for a moment, steam the broccoli florets until they are bright green and tender.
Serve the garlic herb steak bites immediately with the steamed broccoli on the side.
