Step 1

Preheat oven to 200°C. Line a baking tray with non-stick baking paper. Place potatoes and pumpkin on the tray and bake in oven for 1 hour or until tender. Set aside for 20 minutes to cool.

Step 2

Peel the potatoes and pumpkin and place in a large bowl. Season with salt and pepper. Use a potato masher or fork to mash until smooth.

Step 3

Add the flour and stir with a wooden spoon until combined. Turn dough onto a lightly floured surface and knead until smooth. Divide dough into 4 portions. Roll 1 portion into a 2cm-diameter log. Use a lightly floured knife to cut into 2cm pieces. Place on the lined tray. Repeat with remaining dough portions.

Step 4

Roll each piece of dough into a ball. Roll each ball over the back of a lightly floured fork. Place on the tray.

Step 5

To make the leek & basil butter, heat the oil in a frying pan over medium-high heat. Add the leek and cook, stirring, for 1-2 minutes or until golden. Use a slotted spoon to transfer to a plate lined with paper towel. Add the basil and chilli to the pan and cook for 1 minute or until crisp. Transfer to the plate. Add butter to the pan and stir for 1-2 minutes or until melted and golden. Pour into a small jug and cover to keep warm.

Step 6

Bring a saucepan of water to the boil over high heat. Add one-quarter of the gnocchi and cook for 2-3 minutes or until the gnocchi rises to surface. Use a slotted spoon to transfer to serving plates. Repeat with remaining gnocchi. Drizzle over butter and top with leek, basil and chilli to serve.
