Method
For the Roast Beef
- Using a sharp pointed knife, score the fat on the top of the beef.
- Heat the oven to 190°C. Heat a large frying pan, add 1 tablespoon vegetable oil, and brown the beef all over.
- Remove the beef from the pan and brush the scored, seared fat with mustard. Sprinkle generously with cracked black pepper.
- Lay the carrots, onion, garlic, and thyme in a large roasting tray.
- Place the beef on top and roast for 40–50 minutes.
- Remove from the oven and allow the beef to rest.
For the Broccoli
- Put the broccoli in a bowl and dress with olive oil, salt, and pepper.
- Heat a griddle pan over medium heat and grill the broccoli until charred and cooked through.
- Transfer to a warm serving plate, drizzle with extra virgin olive oil, and finish with a squeeze of lemon.
For the Potatoes
- Heat the oven to 200°C.
- Place the potato between two wooden chopsticks or skewers and slice carefully, stopping at the chopsticks to avoid cutting all the way through.
- Place the potatoes cut-side up on a baking tray and drizzle with oil, rubbing well to coat and get oil between the slices.
- Add the bashed garlic and rosemary, season well, and roast for 50 minutes to 1 hour until tender and crisp.
- Baste with the oil in the tray halfway through cooking for extra crisp potatoes.
For the Salsa Verde
- Put all ingredients into a blender and blend until combined.
- Season well with salt and pepper.
