Preheat your oven to 425°F for the roasted potatoes and prepare a baking sheet lined with parchment paper.
Wash the baby potatoes and cut them into halves or quarters depending on their size. Toss them with a pinch of salt, black pepper, and a drizzle of olive oil if desired (optional, note: it may slightly increase calories).
Spread the potatoes out on the baking sheet in a single layer and roast in the oven for 20-25 minutes until crispy and golden, stirring halfway through.
While the potatoes are roasting, pat the steak dry with a paper towel. Season both sides with a pinch of salt and pepper.
Heat a skillet over medium-high heat. Once hot, add the steak and sear for about 3-4 minutes per side for medium-rare (adjust time according to preferred doneness).
During the last minute of cooking, add the butter and minced garlic to the skillet. Spoon the garlic butter over the steak to enhance its flavor.
Finally, steam or lightly sauté the green beans until they are tender-crisp, about 4-5 minutes. Season with a small pinch of salt and pepper if desired.
Plate the steak with a side of crispy roasted potatoes and green beans. Drizzle any remaining garlic butter from the pan over the steak for extra flavor.
