Cook 140 g Spaghetti according to the packet instructions - this will be 10-12 minutes.
Drain the pasta (reserving 75 ml Pasta water). Return to the pan with the pasta water,1 tablespoon Marmite, 2 tablespoon Butter, 30 g Parmesan and 1 pinch Sea salt and ground black pepper. Mix well until the butter has melted and all of the spaghetti is coated.
Serve with 3 g Fresh parsley.
Notes
To loosen the sauce up a little, we reserved a little pasta water and stirred it in to the marmite pasta mix. This is optional, but you really shouldn't skip this step. This starchy water it was helps to make the sauce nice and silky and much more of a sauce texture.
You can add an extra kick of flavour by sprinkling some dried red chilli flakes on top before serving.
Add some protein by adding some cooked bacon, grilled chicken breasts or chickpeas.
