Need a family meal that can be ready in 30 minutes? Try this Japanese ketchup spaghetti recipe with bell pepper, mushrooms, garlic, and sausage.
Ketchup spaghetti?! Yes, it’s a spaghetti recipe that is seasoned mainly with ketchup. This ketchup flavored pasta is popular and widely available at 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 is originated in Japan (please let me know if Spaghetti Neapolitan exists in Italy). I want to share this recipe because I had received several requests from readers. They all referred to this dish as “Ketchup Pasta” hence I called it Ketchup Spaghetti.
Origin of Spaghetti Napolitan
There are a few theories of how Spaghetti Napolitan (or Naporitan) or Ketchup Spaghetti originated. The strongest theory is that it’s originated in Yokohama during the post war. Around 1950s, the head chef at the New Grand Hotel in Yokohama created this recipe when he was inspired by the spaghetti and tomato sauce dish served for the American military. Since tomato sauce was a rare ingredient, so ketchup was used as a substitute for the pasta. He then named it Spaghetti Napolitan, or napoli, after Naples, Italy.
Around the same time, Japan started to open itself to the world and new ideas from the west were considered fashionable. These newly westernized dishes like Spaghetti Meat Sauce and Spaghetti Napolitan received amazing responses that they became mainstays in the cafes and Japanese home kitchens. Until these days, the two dishes are still two of the most popular western influenced pastas in Japan.
The genius about Spaghetti Napolitan is it utilizes most of the pantry staples at your kitchen. 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. There’s flexibility in the recipe too, so you can throw in whatever happens to be in-season or on-hand in your kitchen. This dish is really easy to make and the flavor is kids-friendly. It makes the ideal meal for quick dinner if you have a family with young children. My kids often scream ‘Ketchup Spaghetti’ when I ask what kind of pasta they would like for dinner. I hope you will give this ketchup spaghetti recipe 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.

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.
