Ingredients:
- 2 lb Top Sirloin Roast
- 2 tbsp Extra Virgin Olive Oil
- 1 tbsp Coarse Kosher Salt
- 2 tsp Cracked Black Pepper
- 3 cloves Garlic, minced
- 1 tbsp Fresh Rosemary, finely chopped
- 1 lb Fingerling Potatoes, halved lengthwise
- 3 medium Carrots, peeled and cut into 1-inch coins
- 2 large Parsnips, peeled and cut into 1-inch chunks
- 1 medium Red Onion, cut into thick wedges
- 2 tbsp Avocado oil
- 1 tbsp Balsamic Vinegar
Instructions:
- Preheat your oven to 425°F (220°C) and place an empty extra-large heavy-duty rimmed baking sheet inside to harness conductive heat.
- In a large mixing bowl, toss the halved potatoes, carrots, parsnips, and red onion wedges with avocado oil, balsamic vinegar, and a pinch of salt until evenly coated.
- Pat the beef roast bone-dry with paper towels to ensure a proper Maillard reaction. Rub the surface with olive oil, kosher salt, black pepper, minced garlic, and chopped rosemary.
- Carefully remove the preheated sheet pan from the oven. Place the beef roast in the center of the pan and arrange the vegetable mixture in a single layer around the meat.
- Roast for approximately 40 to 45 minutes. Use an instant-read digital thermometer to monitor the beef; remove from the oven when it reaches an internal temperature of 135°F (57°C) for medium-rare and the onions are charred at the edges.
- Transfer the beef to a cutting board and let it rest for 10 minutes before slicing against the grain to maintain succulence. Carryover cooking will bring the temp up to 145°F during the rest.
- If the vegetables aren't quite tender, slide the pan back in for 5 more minutes while the meat rests. They should be soft enough to crush with a fork.
