Preheat your oven to 400°F (200°C) to prepare for roasting the vegetables.
Prepare the sweet potato by piercing it with a fork and microwaving for 4 minutes until soft, then slice it in half.
Mince the garlic cloves, fresh rosemary, and fresh thyme finely on a cutting board.
In a small bowl, combine the minced herbs and garlic with half of the olive oil, sea salt, and black pepper to form a thick paste.
Pat the beef eye round steak dry with a paper towel and rub the herb paste generously over both sides of the meat.
Heat a cast-iron skillet over medium-high heat with the remaining olive oil until shimmering.
Sear the steak for 3 minutes per side to develop a golden-brown crust, then remove from heat and let rest for 5 minutes.
While the steak rests, place the asparagus on a baking sheet, drizzle with a tiny bit of water or oil spray, and roast in the oven for 10 minutes.
Slice the rested steak thinly against the grain and serve immediately with the roasted asparagus and the warm sweet potato half.
