Cooking Steps

Roast the potatoes
1

• See ‘Top Roast Tips!’ (below left).
• Preheat oven to 220°C/200°C fan-forced.
• Cut potato into bite-sized chunks.
• Place potato on a lined oven tray. Drizzle with olive 
oil, season with salt and toss to coat.
• Roast until tender, 20-25 minutes.  

Cook the steak
2

• In a large frying pan, heat a drizzle of olive oil 
over high heat. Season beef tri tip all over, then  
add to the 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. 
TIP: The meat will keep cooking as it rests!

Get prepped
3

• While the tri tip is roasting, trim green beans.
• Trim ends of asparagus.
• Thinly slice brown onion.
• Finely chop garlic.
• Pick thyme leaves. 

Cook the veggies
4

• While the steak is resting, return the frying pan to 
medium-high heat with a drizzle of olive oil. Cook 
asparagus, tossing, until tender, 5-6 minutes. Add a 
dash of water to pan to help asparagus cook.
• Add green beans, tossing, until softened,  
2 minutes.
• Add half the garlic and cook until fragrant,  
1-2 minutes.
• Transfer to a medium bowl and cover to keep warm. 

Make the creamy onion sauce
5

• Return frying pan to medium-high heat with a 
drizzle of olive oil. Cook onion, stirring, until tender, 
4-5 minutes.
• Stir through remaining garlic and thyme until 
fragrant, 1 minute.
• Add light cooking cream and the water and simmer 
until thickened, 2-3 minutes. Season  
with pepper. 
TIP: Add the steak resting juices to the sauce for extra 
flavour! 

Finish & serve
6

• Sprinkle pine nuts over the greens. Season with salt 
and pepper, then toss to combine.
• Very thinly slice beef. 
• Sprinkle over sea salt flakes.
• Divide the roast beef tri tip, potatoes and nutty 
sautéed greens between plates.
• Spoon the decadent onion sauce over the beef to 
serve. Enjoy!
