One Pan and One Pot

One-Pot Tomato Basil Pasta

Everything goes in together: spaghetti, tomatoes, onion and garlic are covered with boiling water, and in ten minutes the water turns into a glossy sauce. It sounds like a trick, but the pasta's starch does the work — all we have to do is stay close and stir often.

Ingredients

  • What to use instead

    Traditional parmesan is made with animal rennet. For a strictly vegetarian meal, choose a hard cheese made with microbial rennet — it's usually stated on the label.

Makes: 4 servings

Method

  1. Step 1: Put everything in

    Use a wide, deep frying pan or sauté pan about 28 cm across, so the spaghetti can lie flat. Add the pasta, tomatoes, onion, garlic, chilli, oil, salt and half the basil leaves.

  2. Step 2: Add boiling water

    Boil the kettle and pour the water into the pan — the pasta should be almost fully covered. Set over high heat and bring to the boil.

  3. Step 3: Separate the pasta

    As soon as the spaghetti starts to soften, after 1–2 minutes, use tongs to push it under the liquid and separate the strands so they don't stick together in clumps.

  4. Step 4: Boil and stir

    Keep it at a lively boil over medium-high heat for 9–11 minutes, turning the pasta with tongs every minute. The tomatoes will burst and the liquid will gradually thicken and turn orange-red.

  5. Step 5: Check doneness

    It's ready when the pasta is al dente and just a few spoonfuls of thick, glossy sauce remain in the pan. If the liquid has gone but the pasta is still firm, add 50–100 ml boiling water; if there's too much liquid, boil for another 1–2 minutes.

  6. Step 6: Finish and serve

    Take off the heat, add the parmesan and the remaining basil, tearing the leaves by hand, and season with pepper. Toss until the sauce turns creamy, taste for salt and serve at once.

Tips & variations

  • Tip

    The width of the pan matters: in a tall, narrow pot the pasta cooks unevenly. If you don't have a wide pan, snap the spaghetti in half.

  • Tip

    Stir more often in the last 3 minutes: there's more starch in the pan by then, and the pasta likes to catch on the bottom.

  • Swap

    Traditional parmesan is made with animal rennet. For a strictly vegetarian meal, choose a hard cheese made with microbial rennet — it's usually stated on the label.

  • Variation

    Stir in 100 g baby spinach at the end, or dot the top with small mozzarella balls that melt slightly into the hot pasta.

  • Storage

    Best eaten straight away. Keep leftovers in the fridge for up to 2 days and reheat in a pan with a splash of water.
