Author Notes

Spaghetti Napolitan (named after Naples, Italy), or what I like to call "ketchup spaghetti," was invented by the head chef at the New Grand Hotel. Since tomato sauce was a rare ingredient in postwar Yokohama around the 1950s, ketchup was used as a substitute. —Eric Kim

Ingredients
  • 4 ounces spaghetti (I prefer thin, but regular is fine)
  • Kosher salt, to taste
  • 1 large organic egg
  • Olive oil, for frying egg
  • Freshly ground black pepper
  • 2 tablespoons unsalted butter, divided
  • 1/2 red onion, thinly sliced
  • 1/2 red bell pepper, thinly sliced
  • 2 tablespoons ketchup^
  • 1 pinch sugar
  • 1 tablespoon milk
  • 1/4 cup Parmesan
  • 1/4 cup fresh chopped parsley
Directions
  1. Bring a medium pot of water to a boil, season with salt, and cook the spaghetti according to package instructions.
  2. Meanwhile, fry egg in some olive oil, sunny-side up, until crispy at the edges. Season with salt and pepper and set aside.
  3. When pasta is done, reserve 1/2 cup of the cooking water, drain, and set spaghetti aside for later.
  4. In the now empty pot, prepare the sauce: Melt 1 tablespoon butter and sauté onion and bell pepper for 2 to 3 minutes, until just starting to caramelize.
  5. Add the remaining tablespoon butter, then stir in the ketchup and sugar. Sauté for 2 to 3 minutes, until ketchup has cooked down a bit. Splash in milk, along with the cooked and drained spaghetti. Toss with the sauce and fry pasta for a minute or so, adding some of the reserved cooking water to thin out as needed.
  6. Season with salt and pepper and stir in the Parmesan and parsley. Plate spaghetti, then top with the fried egg.
  7. ^If you've got tomato paste lying around, then substitute 1 of the tablespoons ketchup with tomato paste for a deeper, richer tomato flavor.

This was one of my comfort food growing up in Japan. For all those people calling this food vile, disgusting, etc, no one in Japan thinks this is real Italian food. It was a Japanese creation post war (as Eric has mentioned); along with Japanese curry (no one in Japan thinks it’s Indian curry), and Japanese hambagu (hamburger patties).

Bro, I’m Italian and trust me, if you go to Naples or everywhere in Italy and you show to someone this, I don’t think you will still alive. KETCHUP AND PASTA IS ILLEGAL!!! P.s. ketchup and tomato sauce are not the same thing, so please take the right decision and be a good chef! <3

Why would you fry the egg ahead of time, rather than just before serving so it's still hot?
Eric K. March 8, 2020
Hm, good point. I think I did that so you wouldn't have to dirty another pan. I suppose you could in theory make the spaghetti first, plate it, clean the pan (there'll be some gunk), and fry an egg in there. Or just fry in a separate pan so everything stays hot. Not important; do you!

And here I thought maybe I was missing something important! (Hate missing things...)

Waiting to make this when my husband is out of town. He-will-not-eat ketchup. I'm thinking of adapting it to a one pot Martha Stewart style pasta dis and adding cubed fried spam.

What a fantastic recipe. I quadrupled it to feed our family of 6, and it was a complete hit!!! Thank you for this simple AND flavorful version. This will be a staple from now on.
