Prep: Slice the potatoes in half and cut the broccoli into bite sized pieces. Mince the garlic and parsley. Cut the steaks into 2 inch pieces and pat them dry on all sides with a few paper towels to dry the pieces. Season lightly with salt and pepper.
Cook the vegetables: Heat 2-3 tablespoons of oil in a large cast iron skillet over medium heat. Set the potatoes in the skillet, cut side down. Cook for about 7-8 minutes, or until the cut side begins to get crispy and will easily release from the skillet.Flip the potatoes and add the broccoli. Cook together for another 7-8 minutes, or until the potatoes are cooked through and the broccoli is softened. Transfer everything to a large plate.
Cook the steak: Heat 2 tablespoons of oil in the same skillet over medium high heat. Once the oil is shimmering, add the steak. Sear the steak for about one minute per side, turning the pieces as soon as they begin to brown, then set the steak aside on the same plate as the vegetables.
Make the garlic butter sauce: Lower the heat. Add the garlic, remaining 2 tablespoons of oil, and butter to the skillet. Saute over low heat until the garlic is fragrant, about 3-4 minutes.
Finishing steps: Add the steak and vegetables back into the skillet, turning to fully coat the steak and vegetables in the butter and garlic. Sprinkle with parsley and season lightly with salt and pepper. Serve immediately!

Notes
You can substitute the sirloin steak with another cut of steak of your choice. NY strip and ribeye are good options.
To help create a good sear, pat the meat dry with paper towels before seasoning it.
Only want steak and potatoes in your meal, that's fine! Including broccoli makes this a complete, all-in-one meal.
Reduce the burner heat to medium-low before making the garlic butter sauce. This prevents the garlic from burning.
