Peel and wash parsnips and carrots and cut them into long sticks. Peel beetroot (caution, it stains strongly! Wear disposable gloves) and cut it first into slices, then into sticks. Roughly chop the nuts. Wash rosemary, dab dry, pluck needles and chop.
Preheat oven (electric cooker: 200 °C/circulating air: 180 °C/gas: see manufacturer). Mix vegetables separately with 1 tablespoon of oil, 1⁄3 nuts and rosemary. Season with salt, pepper and 1 pinch of sugar. Arrange the vegetables side by side on a small tray. Bake in the oven for 20-25 minutes.
Heat 1 tablespoon of oil in a frying pan. Fry the minced meat until crumbly. Season with salt and pepper. Grate the Parmesan finely.
Remove the baking tray, pour cream over it and spread minced meat and parmesan cheese on top. Bake in the hot oven for about 10 minutes.
TIP: For a nice colour gradient, dribble the cream over the centre of the vegetables, keep the mould straight when taking it out and try not to tilt it when applying it.
