Method

Step 1

Preparation: Preheat the oven to 200°C. Prepare all ingredients as indicated above.

Step 2

Sweet potato chips: Cut off the ends, then cut them into 1cm slices lengthways and cut those slices into 1cm chips. Place on a tin foil lined baking tray. Drizzle with olive oil, season with salt and pepper, mix and then spread in a single layer. Roast for 25 minutes, until golden and cooked.

Step 3

Caramelised onion: Place a pan on low-medium heat with a generous knob of butter. When the butter has melted, add the onion with a pinch of salt. Cook for 20 minutes, stirring every now and then, until soft and slightly sweet.

Step 4

Mayo sauce: Mix together the mayonnaise, garlic and wholegrain mustard. Set aside.

Step 5

Patties: Mix together the beef mince and fresh rosemary, season generously with salt and pepper and shape into patties (1 per person). Add a drizzle of olive oil to a pan on medium-high heat. When hot, add the patties (they should sizzle when they hit the pan) and cook for 4-6 minutes per side until cooked to your preference.

Step 6

Serve the patty topped with the mayo sauce and caramelised onion. Mix together the tomatoes and baby spinach and serve on the side with the sweet potato chips.
