Why You'll Like This Recipe

  • The pasta cooks in the sauce, so the starch it releases stays in the pan and thickens everything.
  • One pan, no colander, and nothing to drain.
  • Built almost entirely from cupboard ingredients.

Ingredient Notes

Tomato paste
Small amount, large effect. It concentrates the tomato flavour that canned diced tomatoes alone cannot provide, and it thickens the sauce as the pasta cooks.
Broth
The quantity is calculated for 340 g of penne. Different shapes absorb different amounts, so if you switch shapes keep a little extra broth to hand.
Heavy cream
Added at the end over low heat. Cream that boils in an acidic tomato sauce can split, and once it has split it will not come back.

Equipment

  • Large deep skillet or Dutch oven
  • Wooden spoon
  • Measuring cups/spoons
  • Cheese grater

Substitutions

Penne
Any short shape works — rigatoni, fusilli or shells. Long pasta does not, since it will not sit under the liquid.
Heavy cream
Evaporated milk or half-and-half work with a slightly thinner result. Cream cheese, about 60 g, gives a thicker sauce and holds together well.
Parmesan
Pecorino is sharper and saltier — reduce the added salt if you use it. Grate it yourself either way, since pre-grated cheese carries anti-caking starch that goes grainy.

Storage

Storing: Refrigerate for up to 3 days. The pasta keeps absorbing sauce, so reheat gently with a splash of broth or milk.

Frequently Asked Questions

Can you cook pasta directly in sauce?

Yes, provided there is enough liquid for the pasta to absorb. It works because the starch that would normally go down the sink with the cooking water stays in the pan instead, which is what thickens the sauce and makes it cling.

Why is my one-pot pasta sticking to the pan?

There is much less liquid than in a full pot, so the pasta settles on the base. Stir every two to three minutes and keep the heat at medium-low rather than a rolling boil.

My sauce is too thick — what do I do?

Add a splash of hot broth or water and stir. The sauce should look slightly loose in the pan, because it thickens noticeably as it stands.

Can I add chicken or vegetables?

Yes. Cook diced chicken first, set it aside and return it at the end with the cream. Spinach can be stirred in during the last minute; firmer vegetables like peppers go in with the garlic.

Can I make this dairy free?

Full-fat coconut milk in place of the cream works, and nutritional yeast can stand in for the Parmesan. The result is different but good — the coconut is noticeable against the tomato.

Why did my sauce split or look curdled?

The cream went in while the pan was too hot. Reduce the heat to low before adding it, and never let the sauce boil once the cream is in.
