150 grams sourdough, crust removed, torn into small pieces
¼ cup (40g) pine nuts
½ teaspoon ground nutmeg
¼ cup (60ml) extra virgin olive oil
Method
1
Preheat oven to 200°C/400°F.
2
Place one sweet potato on an oven tray. Bake for 1 hour or until tender; cool. Reduce oven temperature to 160°C.
3
Meanwhile, peel remaining sweet potatoes. Using a mandoline or V-slicer, cut sweet potatoes lengthways into 3mm thick slices. Trim slices into 6cm x 12cm rectangles; you will need 36 rectangles.
4
Bring a large saucepan of water to the boil; season with salt. Add half the sweet potato slices, boil for 1½ minutes or until softened. Remove from pan with a slotted spoon; place on a tray to cool. Repeat with remaining sweet potato slices.
5
When cool enough to handle, remove skin from baked sweet potato. Place sweet potato flesh in a processor with ricotta; process until smooth. Transfer to a large bowl. Stir in egg, green onion, herbs and half the parmesan. Season.
6
Grease a 4-litre (16-cup) shallow ovenproof dish (or two 2-litre (8-cup) shallow ovenproof dishes). Place 1 heaped tablespoon of filling mixture at the short end of a sweet potato slice; roll to enclose filling. Place, seam-side down, in dish. Repeat with remaining sweet potato slices and filling mixture, until dish is filled in a single layer.
7
Combine sourdough, pine nuts and nutmeg in a medium bowl with remaining parmesan and 2 tablespoons of the oil. Sprinkle mixture over sweet potato cannelloni.
8
Bake for 15 minutes or until top is golden and crunchy.
9
Serve sweet potato cannelloni topped with extra parsley and drizzled with remaining oil.
