Step 1

Use a mandolin to thinly slice the vegetables (approx. 2mm thick), making sure you use a safety handle.

Step 2

Preheat the oven to 140°C fan / 325°F and line a large baking tray with baking paper.

Step 3

Place the vegetable slices in a mixing bowl and drizzle over the olive oil, then add all the remaining seasoning and spices.

Step 4

Give everything a good mix, making sure all the vegetable slices are separated and coated with the seasoning. Transfer to the baking tray, making sure the slices don't overlap (note: you might need to use two or three trays, depending on their size).

Step 5

Place in the oven for approximately 40–50 minutes, checking after 25 minutes and removing any crisps that are already cooked. The beetroot will be the last vegetable ready (it tends to take 20 minutes longer than the other vegetables).
