Preheat your oven to 220°C/200°C fan/gas mark 7.

Chop the potatoes lengthways into 1cm slices, then chop into 1cm wide fries (no need to peel).

Pop the fries onto a large baking tray. Drizzle with oil, season with salt and pepper, then toss to coat. Spread out in a single layer. TIP: Use two baking trays if necessary.

When the oven is hot, bake on the top shelf until golden, 25-30 mins. Turn halfway through.


Meanwhile, peel and grate the garlic (or use a garlic press).

In a large bowl, combine the garlic, half the mustard, breadcrumbs, salt and water for the breadcrumbs (see pantry for both amounts), then add the beef mince. Season with pepper and mix together with your hands. 


Roll into even-sized balls, then shape into 1cm thick burgers, 1 per person. TIP: The burgers will shrink a little during cooking. IMPORTANT: Wash your hands and equipment after handling raw mince.

Pop the burgers onto a large baking tray. Bake on the middle shelf until cooked through, 12-15 mins. IMPORTANT: The burgers are cooked when no longer pink in the middle.

Meanwhile, halve, peel and thinly slice the onion.


Pop a large frying pan on medium heat and melt in the butter (see pantry for amount).

Once melted, add the onion, season with salt and pepper and fry, stirring occasionally, until golden, 10-12 mins. Add the sugar (see pantry for amount) and half the cider vinegar. Cook until caramelised, 1-2 mins more.

Meanwhile, in a medium bowl, combine the olive oil and sugar for the dressing (see pantry for amount) and remaining cider vinegar. Season with salt and pepper. This is your dressing.

Grate the cheese. Halve the burger buns.


Once the burgers are cooked, carefully place the cheese on top of the burgers and pop back into the oven until the cheese has melted, 2-3 mins.

Pop the buns into the oven to warm through, 2-3 mins.

In a small bowl, mix the remaining mustard and mayo (see pantry for amount).

Just before everything's ready, toss the baby leaves through the dressing.


When everything's ready, spread the mustard mayo over the bun bases.
Top the bases with the cheeseburger and load on the caramelised onion, then sandwich shut with the bun lids.

Serve the fries and baby leaf salad alongside.
