Instructions
- Preheat the oven to 240°C/220°C fan/gas mark 9.
- Chop the potatoes into 2cm chunks.
- Pop them onto a lined baking tray.
- Drizzle with oil and season with salt and pepper.
- Roast on the top shelf of the oven until fork tender, 25-35 mins. Turn the tray halfway through cooking.
TIP: Use two baking trays if necessary.
- Trim the leek. Halve lengthways. Thinly slice one-half widthways (double for 4p).
- Place a pan over medium heat with a knob of butter and a drizzle of oil.
- Once hot, add the sliced leek and season with salt and pepper.
- Cook until softened, stirring occasionally, 6-8 mins.
- Once softened, remove from the pan and set aside.
- In a large bowl, combine the Worcester sauce, half the mustard (double for 4p) and breadcrumbs.
- Add 2 tsp water and ¼ tsp salt (double both for 4p).
- Add the beef mince, season with pepper and mix everything together by hand.
- Roll into evenly-sized balls, then shape into 1cm thick burgers—one per person. IMPORTANT: Wash hands and equipment after handling raw mince.
TIP: The burgers will shrink a little during cooking.
- Return the pan to medium-high heat with a drizzle of oil.
- Once hot, fry the burgers until browned on the outside and cooked through, 10-12 mins. Turn every 2-3 mins, adjusting the heat if necessary.
- Once cooked, remove the pan from the heat. IMPORTANT: Burgers are cooked when no longer pink in the middle.
- Place some cheese on top of each burger.
- Cover the pan and set aside (off the heat) until the cheese melts, 3-4 mins.
- While the burgers cook, separate the buns.
- Pop into the oven to warm through, 2-3 mins.
TIP: Keep an eye on them so they don't burn!
- To assemble the burgers, spread some aioli and ketchup over each base bun.
- Top with the cheesy beef burger and buttered leeks.
- Sandwich closed with the top bun.
- Serve with crispy potatoes alongside.
