Yakisoba Pan Japanese Noodles in a Bun

Yakisoba pan is a popular Japanese dish that features stir-fried noodles in a hotdog bun & whilst that may sound crazy they are delicious!

I make my take on this recipe with thick udon noodles and add shiitake mushrooms to make this wonderfully easy vegan lunch.

Japanese Noodle Sandwich

Yakisoba pan sounds absolutely bonkers, it’s essentially a Japanese noodle sandwich served in a hotdog bun!

I came across the idea when I developed my yaki udon stir fry recipe and have been obsessed with it ever since.

I guess it is a sideways glance at my childhood. A time when spaghetti hoops on toast and even spaghetti bolognese toasties were firm favourites.

These noodle buns are cheap street food in Japan and apparently came about in the 1950’s when there was an explosion of cheaper wheat-based products flooding the market.

I love them deeply in my short time playing with the idea, I love to use thick udon noodles and make my take on a yakisoba (ish) sauce. This version is designed to be vegan, however I also have a non-vegan version in my beef yakisoba recipe.

They are without question my favourite lunch right now and I am eating it 3-4 times a week, oopsie!

Frequently Asked Questions

Can I use a different type of noodle?

Yes, use anything you like. I have a huge food crush on Udon noodles at the moment and it is why they appear in this recipe.

If you like them then you must check out my ginger chicken udon noodle stir fry!

Why do you butter the buns?

This is the sort of food that gets wrapped in clingfilm and sold throughout the day and as a result, the butter is used to offer protection for the bread. Essentially it stops it from going soggy.

Can I prepare this in advance?

The recipe is designed to make four sandwiches. I usually make up the noodles and leave them in the fridge, then make a sarnie when I am ready. The noodles will be fine in the fridge for 3-4 days.

You can wrap them in cling film and take them to work too, just make sure to use loads of butter!

Can I use other ingredients instead of mushrooms?

Absolutely, I’ve given a few thoughts and ideas in the serving suggestions section below.

You mention Japanese mayonnaise, what is it?

Japanese mayo is made using just the egg yolk rather than the whole egg, which is exactly the approach I take when I make homemade mayonnaise!

It also uses a combination of rice wine vinegar, malt vinegar and cider vinegar. Then a pinch of MSG and some mustard delivers a different flavour sensation and lovely texture.

Serving Suggestions

Rather than my usual serving suggestions I will use this section to sprinkle some ideas for different toppings or variations on this yakisoba pan recipe.

To begin with, you could use any noodle recipe that you like within reason. The main thing that you need to do is to ensure that they are quite “dry” to stop the hotdog buns from disintegrating and you from wearing your lunch.

I have a few options here that would work. Everything from my cold soba noodle salad and these sesame noodles to my sweet chilli noodles and sweet and sour noodle stir fry.

You can add meat or even seafood if you wish, but that will reduce the shelf life of the noodles.

If I am adding meat I like to keep it a little Japanese and use some strips of katsu. My chicken katsu curry, or tonkatsu recipes are a good start, you could even add some tofu katsu.

Yakisoba Pan Recipe

Prep Time: 10 minutes
Cook Time: 10 minutes
Total Time: 20 minutes

The idea of a noodle sandwich sounds a bit crazy but yakisoba pan is incredibly cheap "street food" in Japan and it is pure genius as far as I am concerned!


  • 4 Tbsp Light Soy Sauce
  • 1 Tbsp Vegan Oyster Sauce
  • 1 Tbsp Tomato Ketchup
  • 1 Tbsp Hendersons Relish
  • 1 Tbsp Mirin
  • Pinch of MSG
  • 400g (14oz) Cooked Udon Noodles
  • 100g (1-1½ Cups) Shiitake Mushrooms
  • 2 Garlic Cloves
  • 1 Tbsp Cooking Oil
  • 4 Large Hotdog Buns
  • 30g (2 Tbsp) Butter
  • 1 Tbsp Pickled Ginger
  • 3 Spring Onions
  • Sesame Seeds


  1. Mix together the soy sauce, oyster sauce, tomato ketchup, Henderson's relish, mirin and MSG, then set aside.
  2. Cook the udon noodles as per the instructions on the packet, I usually use wok-ready noodles. I soak them in boiling water for a couple of minutes, then separate them and refresh them in cold water.
  3. Peel the garlic and chop it as finely as you can.
  4. Slice the shiitake mushrooms into 3-4mm (⅛") thin slices.
  5. Heat a wok over a very high heat and when it begins to shimmer add the oil.
  6. Throw in the shiitake mushrooms and store fry for 2 minutes.
  7. Throw in the garlic and stir fry for 30 seconds.
  8. Add the drained noodles and stir fry for 1 minute.
  9. Push the noodles to the side of the wok add the sauce and then cook until the sauce reduce almost all of the way down and coats the noodles nicely without there being a pool of sauce in the wok.
  10. Remove from the heat, transfer to a bowl and allow to cool a little.
  11. Slice the hotdog buns vertically but not all of the way through, then generously butter them on both sides of the cut.
  12. Slice the spring onions at a 45° angle as thinly as you can.
  13. Load the hotdog buns with the noodles, then top as desired with pickled ginger, spring onions, sesame seeds and mayonnaise. Special props if you use Japanese mayo!
