Meanwhile, cook spaghetti in a large saucepan of boiling, salted water, following packet instructions, until tender. Reserve 1 cup of the cooking water, then drain.

Heat oil in a large non-stick frying pan over medium heat. Cook sage for 1-2 minutes, until leaves start to crisp. Remove sage with tongs and transfer to a paper towel-lined plate to drain.

Add garlic to the pan and cook, stirring occasionally, for 1-2 minutes, until light golden. Stir in ⅔ cup (165ml) of the reserved cooking water and bring to the boil. Boil for 2-3 minutes, until liquid reduces by about half. Add spaghetti and pumpkin. Season with salt and pepper and toss to combine. Add remaining reserved cooking water if needed to loosen the spaghetti. Divide the spaghetti among 4 bowls. Scatter over sage and walnuts. Serve.
