Cooking Steps

PDF

1

• Preheat oven to 240°C/220°C fan-forced. Cut the potato into fries, then place on a lined oven tray.

• Drizzle with olive oil, season with salt and toss to coat. Bake until tender, 25 minutes.

• Remove from the oven, then sprinkle with grated Parmesan cheese and bake until golden and crispy, a further 5-8 minutes.

2

• While the fries are baking, thinly slice onion and button mushrooms. Pick thyme leaves.

• In a large bowl, combine garlic & herb seasoning and a drizzle of olive oil. Add beef, season with salt and pepper and turn to coat.

3

• In a large frying pan, heat a drizzle of olive oil over high heat. Cook bacon and mushroom, stirring, until golden, 3-4 minutes.

• Reduce heat to medium, then add onion, and cook, 4-5 minutes.

• Add the thyme, balsamic vinegar, water and the brown sugar and mix well. Cook until dark and sticky, 3-5 minutes. Transfer to a bowl and cover to keep warm.

4

• Wipe out the frying pan, then return to medium-high heat with a drizzle of olive oil.

• When oil is hot, cook the beef for 4-5 minutes each side for medium-rare, or until cooked to your liking. Cook in batches if your pan is getting crowded. Transfer to a plate to rest.

5

• When the fries have 5 minutes cook time remaining, bake ciabatta directly on the wire oven rack until heated through, 5 minutes.

• Meanwhile, combine salad leaves and a drizzle of balsamic vinegar and olive oil in a second medium bowl. Season to taste.

6

• Slice the seared steak. Slice ciabatta in half, then spread with some garlic aioli.

• Top with steak, caramelised onion, mushrooms and dressed salad leaves.

• Serve with Parmesan fries and Italian truffle mayonnaise. Enjoy!
