Ketchup Spaghetti スパゲッティーナポリタン

Ketchup Spaghetti | Easy Japanese Recipes at JustOneCookbook.com

Ketchup spaghetti?!  Yes, it’s a spaghetti recipe that is seasoned mainly with ketchup.  This ketchup flavored pasta is popular and widely available in cafe restaurants in Japan and we call it Spaghetti Napolitan (スパゲッティーナポリタン).

From what I can find on the web, the recipe was originated from Japan (please let me know if Spaghetti Neapolitan exists in Italy).  I want to share this recipe because recently I had received several request from readers.  They all referred to this dish as “Ketchup Pasta” hence I called it Ketchup Spaghetti.

There are a few theories of how Spaghetti Napolitan or Ketchup Spaghetti originated.  The strongest theory is that it’s originated in Yokohama during the post war.  Around 1950s, a chef at the New Grand Hotel in Yokohama created this dish when he was inspired by one of the food served for the American military, which was spaghetti mixed with tomato Ketchup.

Around the same time in Japan, Japan started to open itself up to the world and tomato sauce was a rare ingredient, so ketchup was used as a substitute instead.  The Japanese enjoyed new westernized dishes like Spaghetti Meat Sauce and Spaghetti Napolitan.  Even now these dishes are still two of the most popular western influenced pasta in Japan.

This dish is really easy to make and the flavor is kids-friendly as well.  The common ingredients include onion, mushrooms, green bell peppers, and sausages (ham or bacon).  It’s seasoned with ketchup and Parmesan cheese, and served with Tabasco sauce.  I hope you want to give it a try.  Trust me, it’s delicious!

Now let’s go over the recipe first before my husband Shen talks about his review on the wine that we pair up with Ketchup Pasta.

Ketchup Spaghetti Recipe
 
Prep time
Cook time
 
Serves: Serves 2
Ingredients
  • 7 oz (200g) spaghetti
  • 1 garlic clove
  • ¼ - ½ onion
  • 6 sausages (I use Japanese “kurobuta” (black pork) sausages) or 2 Italian sausages
  • 1 bell pepper
  • 4-6 mushrooms
  • 2 Tbsp. olive oil
  • 2 Tbsp. milk
  • 2 Tbsp. freshly ground Parmesan cheese
Sauce
  • 4 Tbsp. Ketchup
  • 1 tsp. Worcestershire sauce
  • ¼ tsp sugar (optional)
  • 1-3 Tbsp. pasta cooking water
  • Salt
  • Freshly ground black pepper
Instructions
  1. Bring a large pot of salted water to boil. Cook the pasta according to the package directions.
  2. Meanwhile, mince the garlic clove and slice onion, sausages, bell pepper and mushrooms.
  3. In a large skillet or sauté pan, heat olive oil over medium heat. Add the garlic and sauté for 1 minute, just until golden and fragrant.
  4. Add the onions to the pan and sauté for 2-3 minutes.
  5. When the onions are wilted, add the sausages and sauté for 1 minute.
  6. Add the bell peppers and mushrooms and sauté until everything is cooked.
  7. Add the Sauce ingredients: Ketchup, Worcestershire sauce, and sugar (optional). When the sauce thickens, add the pasta cooking water. Season with salt and pepper to taste.
  8. As soon as the pasta is cooked and drained, add to the pan and toss to combine using tongs.
  9. Add the milk and Parmesan cheese and toss to combine. Serve immediately in warmed plates.

We enjoy drinking wine with our pasta dinner.  The acidity of wine refreshes the palate from the pasta sauce.  Recently we paired the Pfendler 2011 Pinot Noir with ketchup it worked out very well.  The pinot was very smooth yet surprisingly complex for a young wine.  Typically young wines do not have so many layers of deliciousness.  It is an earthy pinot with just a hint of berries and very slight acidity.  The winemaker describe it with layers of tea leaves, and dark chocolate and I couldn’t agree more.   The flavor leans towards spice rather fruity for a pinot and I would highly recommend to drink this with cheese or other strong flavored food.

    Yeah, there is a Neopolitan sauce. As I understand it it’s a ragu, like bolognese, but made with whole meat pieces. I’m running to google now to learn more!

      Hi Mags! Thanks for your input! I think there may be a ragu called Neapolitan (I saw one video which an Italian chef was making Neapolitan pasta), but definitely NO ketchup. :D

    I thought a ketchup pasta sauce would be sketchy (as in lacking in substance and depth) and too sweet due to the ketchup but with the other ingredients it looks good. The wine sounds very intriguing.

    My mother made ketchup spaghetti, though instead of kurobuta sausage she used sliced bologna. She was from the Yokohama area, so I’m guessing that’s where she learned to make this particular spaghetti sauce. Also, “real” meat was hard to come by after the war, so I suspect the bologna was a postwar staple just as Spam was in the UK.

    Unfortunately, I grew up and took cooking classes from chefs who looked down on ketchup, so I never made the dish myself. When my mother died, I was sorry I didn’t write down her recipe for ketchup spaghetti—until now. Thank you so much for posting this!

    • Nami April 22, 2013, 10:32 am

      Hi Eleanor! This spaghetti became popular in Yokohama, but now it’s pretty much all over the place in Japan and always found in Yoshoku (western style) restaurants and cafes. :)

      Haha, I understand about the ketchup. I’m not a huge ketchup fan too (I eat french fries without dipping in ketchup until I get bored with salt taste…then I’d dip in ketchup). Hope you can recreate your mom’s flavor!

    Wondering if you’ve ever run into a recipe for: ume spaghetti? It has shiso leaves in it. Or-maybe it is shiso spaghetti? I had it at a restaurant in Carson (or Cypress) in So CA: Hiro’s Cafe. It was so delicious!

    This is how we cook spaghetti when I was growing up. We used Ketchup as sauce and we used sliced hotdogs. But you added a lot more goodies in there that is why your spaghetti is a lot more special and I bet taste a really good. Have a nice weekend to you and your family, Nami. :)

    Hi Nami, I feel so bad I haven’t stopped by lately. It seems like the weekends are when I’ve had time to visit most people, I’ve just been so busy. I do read many of your posts though.

    My mom always made spaghetti with ketchup and then doctored it up and I loved it. As a child I lived on the stuff – couldn’t get enough of it. I would still eat it daily if my figure would allow it.

    This sounds so good. I like all the ingredients used and can actually taste how good this is. The addition of milk adds just a touch of creaminess to take this pasta to the next level. Very nice recipe. Hope you and your family are well.

    When I was a teenager, I used to eat similar in a Japanese cafe in Isetan, Singapore. I remember always ordering the same dish whenever I visit the cafe. So it must be delicious. I don’t remember the name of the dish but it was tomato-based and very unlike the typical marinara. Maybe it has ketchup in there?

I’ve tell him many times that ketchup are made from tomatoes, but he just insist he doesn’t like tomato but adores ketchup. hahahaha….Anyway, back to your recipe and review. I love how simple this spaghetti is to prepare. :) I know my kids will finish dinner in no time if I make this. The Pfendler 2011 Pinot Noir sounds like something my hubby and I would love to enjoy with pasta. We love wine that are dry. Fruity ones are too sweet for our taste buds. :P

    Hi Nami,
    I like a lot the pictures you took of this pasta but as an Italian I have to disagree on ketchup pasta… in Italy ketchup is baned and never used on pasta. I know, as I see it here in Sweden, outside Italy people eat pasta with ketchup but I really not understand it. We have a basic simple pasta that we call “pasta rossa” (red pasta) and we make with tomatoes sause, you can either use fresh tomatoes in summer or can tomatoes in winter and you cook the sause with onion or garlic and herbs like basil or thyme or any herb you like, and you cook it for a long long time. This basic recipe has many variants in every family and I am sure in Neaples there are differences, they usually use a lot of chili for example (I never heard of spaghetti Neapoletan).
    I do not know why I did not put my family recipe for pasta rossa… I will do it soon since I make this pasta often, when I do not have anything else at home I always have pasta and can tomato. This is a dish all kids love in Italy… and adults too.
    Ciao.

    Hi Nami and Shen! I’ve only heard of ketchup spaghetti from movies. Though I’m not a big fan of ketchup Nami your photos and recipe made my mouth water. I love the addition of Worcestershire sauce and sausage. Okay, I really have to give this a try. Thanks for sharing the history and the wine review.

    P.S. Are tomatoes used in Japanese cuisine now, other than in the pasta dishes you mentioned? Thanks:)

    So, when my husband left Iran to stay in the US, he was only 13. He told me they used to add ketchup to their spaghetti, too. Must be this east meets west thing!!! And look what the US has done to Chinese food. From what I understand, the “traditional” dishes we see in Chinese restaurants in the US are not found in China at all! Go figure!

    Hi Nami, this reminds me a little of the sausage stroganoff Swedish recipe I posted a while ago… key ingredient of ketchup. With pepper and sausage it’s a lovely dish – so simple and hearty and well-loved by everyone I think! I think your dish looks a bit more fancy than my humble version but certainly delicious!

    I can almost taste this. The Filipino version of spaghetti uses ketchup as an ingredient, too. I loved my mom’s version and in fact, I have missed it. One of those dishes that takes you back to childhood. This looks so good, Nami. :)

    It looks way better than it sounds lol. Great history behind it. I would be afraid if it was dripping in such a sauce, this is just a nice little coating.

    Hi Nami, this is a really nostalgic recipe for me. My mom used to make this as a special treat for me and my brother with Ayamas (dunno if you know this Malaysian brand) sausages!

    It does sound like a crowd-pleasing dish! If I were a child I would also go crazy for it (ketchup as a sauce!!!). It’s so interesting that the Japanese love Italian cuisine so much! A Japanese friend told me that Italian pasta restaurants are far from being cheap in Tokyo. I have never tasted Japanese sausage! Definitely something I must plan for next trip.
    Sadly I cannot find the wine here, but I loved the review.

    Very interesting. The first part of this recipe I am very familiar with, but a sauce with ketchup as the base – I have never heard of it. It does look quite easy and actually very good. We don’t use ketchup much; therefore, I have a bottle in the fridge that hasn’t been touched in months. Sounds like this is the perfect use for it. Very interesting post Nami. Thanks!

    This is such a fun recipe, Nami. I’ve tried the pasta before when we frequented a few Japanese-Italian cafes in Japan. Really delicious! What’s missing was of course a good bottle of red wine. We had bubbly water instead:( The use of ketchup is really universal. In Malaysia, ketchup is also used in noodles and rice dishes. It is a great culinary invention, isn’t it?

    Here in Germany many Italian restaurants serve Pasta Napolitana, it’s tomato sauce, like Americans eat spaghetti with marinara sauce

      Thank you so much for letting me know Asami! Some Italian blogger told me that Spaghetti Neapolitan doesn’t exist. It was interesting to hear there is a name “Pasta Napolitana” in Germany. :)

    I have never heard of spaghetti Neapolitan here in Italy, and I am sure most Italians would be horrified at the thought of ketchup with spaghetti. Me too actually, although I see there is a lot more to the sauce than its namesake and it actually looks quite delicious.

    No, they don’t exist in Italy, but I have to admit the look rather good!

    Hi Nami,

    Hope u are having a good weekend.
    I am just wondering if I can use salami instead of Italian sausages. Will that work too?
    Please advise. Thanks!

    Regards,
    Cindy

      Hi Cindy! Thank you, it was busy but we had good weekend. Hope you had good one, too. Sure, you can use salami, ham, any kind of meat you have in your fridge. Hope you enjoy this recipe! :)

    Hi Nami,
    My mother used to cook a lot of that when we were growing up at home (in Paris, but she grew up just after the war near Tokyo so that explains a lot). My brother and I used to love this almost as much as omurice (typical for kids) but at home we just called it akai spaghetti (as in 赤い). And as of this day I am still cooking it on my own (minus the bell pepper that I think kills the onions).
    Thank you for your blog where I can find almost all the dishes I used to eat when I was a kid!
    Best.
    Mayumi.

      Hi Mayumi! I remember it was one of my favorite spaghetti too! It’s so easy to make and we usually have ingredients at home so my mom would cook it sometimes for lunch. “Akai Spaghetti” hehee that’s a cute nickname! I personally don’t eat green bell pepper (I start to get heartburn) but it’s one of ingredients in “classic” napolitan recipe, I think. ;)

    no in Italy they normally don’t use ketchup in their spaghetti. its usually tomatos, tomato paste. Actually using ketchup with any kind of pasta is forbidden but I know italians who do add some ketchup to the marinara sauce.

    • Nami November 5, 2013, 11:53 am

      Hi Silvia! I think this dish is created by Japanese who was working for a hotel in Japan back in the 50s when we get a lot of influence from the Americans. :) Ketchup is very American thing. :) But it’s funny how the name implies Italian… maybe because it’s pasta dish. :)

    Nami, I tried this dish for lunch tonight and I have to admit, it turned out great and so reminded me of dishes I have tried while living in Japan. I just added some red pepperflakes, and used hot Italian Sausage. In the end I added a Tbspoon of Mirin… it was great. Thanks for sharing this recipe.

      Hi Kerstin! Thank you for trying this recipe! The “ketchup” as seasoning sounds a little strange, but when it’s convined with Worcestershire sauce, it is actually really delicious! Good idea to make it spicy with pepper flakes and hot sausages and balance out with mirin. Thank you so much for your kind feedback! :)

      Hi Grace! I use Trader Joe’s organic ketchup. It doesn’t have to be specific brand of ketchup for this recipe, but I try to get organic and good quality ones. :)
