Cooking Steps

Cook the beef
1

• See ‘Top Roast Tips!’ (below left). Preheat oven to 
220°C/200°C fan-forced. 
• In a large frying pan, heat a drizzle of olive oil over 
high heat.
• Season premium sirloin tip all over and add to hot 
pan. Sear until browned, 1 minute on all sides.
• Transfer beef to a lined oven tray and roast for  
15-20 minutes (for a 300g piece), 17-22 minutes 
(for a 450g piece) or 18-23 minutes (for a 600g 
piece) for medium-rare, or until cooked to your 
liking. Remove from oven and cover with foil to rest 
for 10 minutes.

Get prepped
2

• Meanwhile, thinly slice fennel into wedges.
• Trim green tops from Dutch carrots, scrub clean and 
halve lengthways.
• Cut chat potatoes into bite-sized chunks.
• Pick thyme leaves.
• Roughly chop roasted almonds. 

Roast the veggies
3

• Place fennel and carrots on a second lined 
oven tray. 
• Drizzle with olive oil, sprinkle with thyme leaves, 
season with salt and toss to coat.
• Roast until tender, 15-20 minutes. 

Cook the potatoes
4

• While the veggies are roasting, boil the kettle. 
• Half-fill a medium saucepan with boiling water, then 
add a generous pinch of salt.
• Cook chat potatoes over high heat, until just tender, 
12-15 minutes.
• Drain and return potatoes to saucepan.
• Add a drizzle of olive oil and truffle oil, season with 
salt and toss to combine.

Make the gremolata
5

• Finely chop garlic and parsley.
• Zest lemon to get a good pinch, then slice into 
wedges.
• In a small microwave-safe bowl, microwave garlic 
and olive oil (1/2 tbsp per person) until fragrant,  
30 seconds.
• Add lemon zest, roasted almonds, a good squeeze 
of lemon juice and parsley to the garlic oil. Season 
to taste with salt and pepper. 

Finish & serve
6

• Very thinly slice beef. Season with a pinch of 
sea salt flakes.
• Divide roast beef sirloin, truffle chat potatoes, 
roasted fennel and Dutch carrots between plates.
• Drizzle herby gremolata over beef.
• Serve with any remaining lemon wedges. Enjoy!
