In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the halved baby potatoes, ensuring they are evenly seasoned with salt and pepper. Cook for approximately 15-20 minutes, occasionally stirring to promote even browning, until the potatoes are golden-brown and fork-tender. Once cooked, transfer the potatoes to a plate and set aside.
Using the same skillet, increase the heat to medium-high. Add the cubed sirloin steak to the pan, seasoning generously with salt and pepper. Sear the steak for about 3-4 minutes, stirring occasionally, until it’s browned on all sides while remaining tender.
Lower the heat back to medium, and sprinkle in the minced garlic, chopped rosemary, and thyme. Sauté for about 1 minute, or until the garlic releases its fragrant aroma, being careful not to let it burn.
Introduce the unsalted butter into the skillet. Stir well to incorporate the melted butter with the steak and aromatic herbs, ensuring everything is evenly coated and luscious.
Gently return the cooked potatoes to the skillet, mixing them with the steak and garlic butter mixture. Stir everything together to combine and allow it to heat through for an additional 2-3 minutes.
Remove the skillet from the heat and generously garnish with freshly chopped parsley.

For a rustic and inviting look, serve the dish directly from the skillet.
