Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Mince the garlic cloves and finely chop the fresh rosemary and thyme leaves.
In a small bowl, whisk together the extra virgin olive oil, minced garlic, rosemary, thyme, sea salt, and black pepper.
Cut the red potatoes into small 1-inch cubes and toss them with half of the garlic-herb oil on the baking sheet.
Roast the potatoes in the oven for 15 minutes until they begin to soften.
While the potatoes roast, coat the top sirloin steak and trimmed green beans with the remaining marinade.
Remove the sheet from the oven, slide the potatoes to one side, and place the steak and green beans on the other side.
Return the sheet to the oven and bake for 10 to 12 minutes, or until the steak reaches your preferred level of doneness.
Let the steak rest for 5 minutes before slicing against the grain to ensure every bite is juicy and tender.
