Steak, mash and mushroom sauce is a classic combo for a reason, and this dish highlights exactly why. Sirloin steak is cooked just how you like it, and a creamy dreamy mushroom sauce adds rich umami flavour. The roasted baby carrots are not to be overlooked either, adding sweet brightness to your plate!

Produced in a facility that processes eggs, milk, fish, peanuts, sesame, shellfish, soy, tree nuts, and wheat.

Cooking Steps

Roast the veggies
1

• See ‘Top Steak Tips!’ (below left). Preheat oven to 220°C/200°C fan-forced. Boil the kettle.
• Trim green tops from baby rainbow carrots (see ingredients) and scrub them clean.
• Trim green beans.
• Place carrots on a lined oven tray. Drizzle with olive oil, season with salt and pepper and toss to coat.
• Spread out in a single layer, then roast until golden and tender, 20-25 minutes.
• In the last 5 minutes of cook time, add green beans to the oven tray.
• Return the tray to the oven and roast until the beans are tender, 5-7 minutes.

Make the mash
2

• While the veggies are roasting, half-fill a large saucepan with boiling water, then add a generous pinch of salt.
• Peel potato and cut into large chunks.
• Cook potato in the boiling water over high heat until easily pierced with a fork, 12-15 minutes.
• Drain and return to the pan. Add the butter (for the mash), milk and salt to potato. Mash until smooth. Cover to keep warm.

TIP: Save time and get more fibre by leaving the potato unpeeled.

Cook the beef
3

• While the potato is cooking, heat a large frying pan over medium-high heat with a drizzle of olive oil.
• When the oil is hot, cook sirloin steak for 5-6 minutes each side for medium-rare, or until cooked to your liking.
• Using tongs, hold steak upright and sear fat until golden, 1 minute.
• Remove steak from pan, cover and rest for 5 minutes. Season with salt.

Get prepped
4

• Meanwhile, thinly slice button mushrooms. Finely chop garlic.
• Pick rosemary leaves (see ingredients).
• Return frying pan to medium-high heat with a drizzle of olive oil. Add garlic and cook until fragrant, 1 minute.
• Add mushrooms and the butter (for the sauce) and cook, stirring, until browned, 4-5 minutes.

TIP: Run your fingers down the rosemary stalk to remove the leaves easily.

Cook the mushrooms
5

• Reduce heat to medium, then add cream (see ingredients), rosemary and any steak resting juices. Stir until well combined and slightly reduced, 2-3 minutes.
• Season to taste with salt and pepper.

Finish & serve
6

• Thinly slice steak.
• Divide potato mash, roast rainbow carrots and green beans between plates. Top mash with sirloin steak.
• Spoon over the creamy mushroom sauce to serve. Enjoy!
