Buttery tomato and onion pasta sauce
A famously simple sauce: tinned tomatoes simmered with a halved onion and a knob of butter until sweet and velvety. Three main ingredients, no chopping.
You have (Pasta + Tinned tomatoes)
- 400g spaghetti or penne
- 2 x 400g tins whole plum tomatoes
You’d add
- 1 onion, peeled and halved
- 60g butter
- grated Parmesan or hard cheese, to serve
- salt (store cupboard)
Method
- Put the tomatoes, onion halves and butter in the medium saucepan with a pinch of salt and bring to a gentle simmer.
- Cook uncovered for 40–45 minutes, crushing the tomatoes against the side of the pan with a wooden spoon every so often, until the sauce is thick and the butter has pooled on top.
- About 12 minutes before the sauce is ready, cook the pasta in a large pan of well-salted boiling water until just tender. Scoop out a mugful of the cooking water, then drain.
- Lift out and discard the onion (or chop it and stir it back in). Taste the sauce for salt.
- Toss the pasta with the sauce, adding a splash of the cooking water to loosen it, and serve with the cheese.
