Preheat your oven to 425°F.
Wash and halve the baby red potatoes, then toss them in olive oil, salt, and pepper on a baking sheet.
Roast the potatoes in the preheated oven for about 20-25 minutes until they are golden and crispy, turning halfway through.
Season the top sirloin steak generously with salt and pepper on both sides.
In a skillet over medium-high heat, melt the unsalted butter along with the crushed garlic clove. Allow the garlic to infuse the butter for about 1 minute.
Place the steak in the hot skillet and sear for about 3-4 minutes on each side or until it reaches your desired level of doneness.
Remove the steak from the skillet and let it rest for a few minutes, then slice if desired.
Plate the steak alongside the crispy roasted potatoes, drizzling any remaining garlic butter over the top.
Serve hot and enjoy your balanced, flavorful meal.
