Ruby Noodles

Leave it to Nigella to come up with a fantastic and unique noodle dish! It’s red, it’s spicy, it’s cold, and it’s delicious.

In her words, with her beautiful accent: “It’s true that these made their debut in the ‘Christmas Comforts’ chapter of Cook, Eat, Repeat as a sprightly and sharp antidote to all the rich feasting (and also, it must be admitted, because of their fabulously festive colours) but this cold tangle of sour-sweet noodles is to be found on my table all year around.”

The noodles become red after spending some time submerged in beet juice. To gather the beet juice I purchased canned beets, of good quality, drained them, and saved that luscious ruby liquid. I’ve always loved reduced beet juice for vinaigrettes, like this one, but I have to say I’ve never used the juice for spaghetti! It certainly works.

Ms. Lawson suggests that even if you’re hesitant about trying cold noodles, to take that jump. After all, these are flavored with Asian ingredients which work so well with noodles, as we all know!

Ruby Noodles

Scant 1 3/4 cups beetroot juice
2 limes, divided
2 fat cloves garlic
2 teaspoons grated fresh ginger
2 teaspoons Maldon sea salt flakes (or 1 teaspoon fine sea salt)
½ teaspoon dried chilli flakes
12 ounces spaghetti
2 teaspoons toasted sesame oil plus 2 teaspoons more
3 teaspoons fish sauce, divided
1 teaspoon plus 1 tablespoon brown rice vinegar
4 teaspoons soy sauce, divided
Roughly chopped fresh coriander
Finely chopped chives

Put water on to boil for the spaghetti, adding salt as usual when it comes to the boil. Pour the beetroot juice into another pan, also large enough for the pasta later, and add the juice of one of the limes. Peel and mince or grate in the garlic, then stir in (I’d advise against using a wooden spoon, unless you don’t mind its getting stained) the grated ginger, salt and chilli flakes. Once you put the pasta in to cook, bring this pan to a simmer over low heat.

Cook the spaghetti in the salted boiling water for 5 minutes, then drain, add to the simmering beetroot juice pan, turn up the heat so that the beetroot juice bubbles more robustly, and cook it until the pasta is al dente. This can take up to 8 minutes, but check at 5. It really depends on the spaghetti you are using but I find it cooks more slowly in the beetroot juice.

At any rate, you will need to hover over the pan a bit, tossing it around with a pasta fork every now and again to make sure it doesn’t stick. When the spaghetti’s cooked, it will have absorbed all the bubbling beetroot juice, except for a scant, shiny scarlet syrup. If the spaghetti has absorbed all the beetroot juice before it has cooked, add in a little hot water from a just-boiled kettle, very slowly, and in gradual increments, as needed.

Once the pasta is cooked, take the pan off the heat and add 2 teaspoons of the sesame oil, 2 teaspoons of the fish sauce, 1 teaspoon of the brown rice vinegar and 2 teaspoons of the soy sauce, toss well, and decant into a shallow bowl to cool.

It will be quite sticky when cold, but don’t panic. In a little jug, mix together the juice of half a lime, the remaining 2 teaspoons of sesame oil, the tablespoon of brown rice vinegar, the last teaspoon of fish sauce, and the last 2 teaspoons of soy sauce, pour over the noodles and toss to combine.

Taste for seasoning and sprightliness; you may want more lime juice or salt.

Add the chopped herbs, toss to mix, and devour.

    This looks so beautiful! Even though beets are not my favorite vegetable, I just might have to try this one.

      Oh, you don’t taste the beets at all. It’s all about the Asian flavors!

      • Dorothy's New Vintage Kitchen February 3, 2025 at 8:57 AM

        Wonderful, then I’m all in! I’ll feed my husband the beets and indulge in pretty spaghetti!

    The color adds some fun to the spaghetti, that’s for sure. I do think this sounds like a fun recipe to try. 😊

      The Asian flavors are fabulous of course. The color is just added fun!

      Oh, you’re in Thailand, right?! Well, I think this was my first time having cold noodles. I really didn’t think about them being cold. They were just so good!

      • CarolCooks2 February 4, 2025 at 7:53 AM

        Yes I am and even hot I don’t eat many I much prefer rice to noodles or pasta.

      • Chef Mimi February 5, 2025 at 7:19 AM

        Interesting! I think I love all of the different shapes!

    What a cool dish! I love the color. I love beets, so this is fine with me. I also love cold noodles, especially if they have Asian ingredients.

      Exactly Jeff! These are just exquisite!

  12. Charlie DeSando February 4, 2025 at 8:55 AM - Reply

    never thought about doing this, but it reminds me of squid ink, coloring the pasta and adding some taste

    • Chef Mimi February 5, 2025 at 7:19 AM - Reply

      Right! I’ve never done that at home! But I prefer the red….

    I have to colour rice for my husband – he doesn’t think white rice is to his liking and it’s so easy to colour it. I imagine you could just add beet juice to cooking water for pasta too? I wonder? I’d be happy with your lovely red and flavoured cold noodles. Sounds wonderful!

    • Chef Mimi February 5, 2025 at 4:16 PM - Reply

      Oh sure! In this recipe, the pasta gets partially cooked, then finishes cooking in pure beet juice. It works great!

    Beautiful noodles! I’ve actually had pasta with beetroot (pure) for a few times, so I can confirm it’s delicious (yet may not be for everyone’s taste.)

      It too me a long time to enjoy beets. I mean, they do taste like dirt! And these noodles have Asian flavors so anyone who doesn’t love beets won’t be bothered by these!

    Coming in from a week without Internet am very glad indeed to find this delight to read! Love beetroot and all your other ingredients and cannot wait to have a ‘local’ taste of this! And am a Nigella ‘fan’ also . . .

    Just showed this to my husband, and we are going to make this for our kids on Valentines Day. Hopefully it’s both fun, and a good way for them to try beets haha Thanks for sharing this.

      You don’t even have to tell them! It’s just for the color!!! Sweet idea.

    What a cool recipe, Mimi! I have used the beet juice for homemade pasta and for risotto, but have never seen anything like this (or your vinaigrette). Thanks for the intro to this recipe.

      I know! And white bean dip! These noodles are so pretty, but they’re also delicious. Of course!

    Nigella always knows how to bring something unexpected to the table! Love the idea of using beet juice to infuse both color and subtle earthiness into the noodles. The balance of sour, sweet, spicy, and umami sounds absolutely perfect, definitely adding this to my must-try list.
