A copycat recipe for Marugame’s hot & cold bukkake udon. If you mix the egg with the beef, it tastes just like sukiyaki! Perfect for lunch. If you skip the meat, it becomes torotama udon.

About this recipe:
I saw a commercial this morning and created this recipe in my head, then cooked it for real and it turned out delicious. I went to the Marugame in the nearby Aeon mall to taste the original and made a few tweaks. The recreation is very accurate, so I’m sharing it here. It’s been a while since my last copycat recipe series.

Steps

1

First, make the easy bukkake udon sauce by mixing the ingredients together. Store-bought sauce is fine too. See ID:20385483 for details.
2

For the soft-boiled egg topping, use the method described in ID:18806656, as it’s different from a regular soft-boiled egg.
3

Mix the ingredients marked with ○ (mirin, soy sauce, sugar) in a bowl. Marinate the beef in this mixture for about 30 minutes. For a more authentic taste, use 2 tsp sugar; the standard is 0.
4

You can serve this dish hot or cold. For the cold version, after boiling the noodles, rinse and rub them well under cold running water.
5

Heat a frying pan over high heat. If you have beef fat, use it; if not, use lard or oil. Sauté the beef with the marinade quickly until just cooked through.
6

Drain the noodles well and place them in a bowl. Pour the sauce over the noodles, then top with grated yam, soft-boiled egg, beef (with sauce), and chopped green onions. Enjoy!
7

For the hot version, microwave the sauce to warm it. You can use freshly boiled noodles or rinse and chill them as for the cold version. If you skip the meat, it becomes regular torotama udon.
8

Surprisingly, this dipping sauce uses no soy sauce! The beautiful pink color is unique and it’s incredibly delicious. See ID:20067410.
9

Exciting news! This recipe was made into a cooking video. Check out the cold Chinese noodles with sesame sauce if you’re interested. See ID:18800354.
10

It’s also delicious with pork! I created a new version with flavors adjusted for pork: Pork Ginger Bukkake Udon. See ID:19759102.
11

I happened to create a recipe very similar to Marugame’s spicy beef dipping udon, inspired by Minatoya-style spicy dipping soba, but using udon. See ID:19476444.
12

This is one of my top 3 new creative noodle dishes. The depth and flavor go beyond this recipe: Chilled Soy Milk Miso Carbonara. See ID:19459459.
13

Here are three recipes from the Matsuridaiko Katsu-don copycat series. Please check them out! See ID:19754258.
14

Another recent creation: a fun salad chicken recipe series, great with both store-bought and homemade chicken. Four recipes so far, with more to come. See ID:18097816.
15

On the day I posted this recipe, I received my first report from Naomi! I’m grateful, as I only made a small adjustment for balance as a single dish.
16

If you try this recipe, I’d love to hear how close you think it is to the original. Thank you!

Thank you for making this again, Ayane mama!
22

It’s getting cooler in the mornings and evenings. Was there a line for this? (laughs) Thank you!
23

Did you make it at night too? Thanks for your report!
24

Shaved burdock root would be a perfect match. I’ll try it next time!
