Japanese udon noodle soup meets breakfast with this delicious Tsukimi Udon! Inspired by the Japanese custom of moon gazing, this unique dish is topped with sunny side up eggs and adorable kamaboko rabbits as well as delicious crispy bacon, tempura flakes and green onions!
What is Tsukimi Udon?
Tsukimi Udon (月見うどん) is an udon dish where an egg is added to Kake Udon, drawing its name “Tsukimi” or “moon-gazing” from the egg’s resemblance to a full moon surrounded by clouds.
Tsukimi is an ancient custom, introduced from China in the Heian period (794-1185), to celebrate the autumn harvest by appreciating the season’s stunning moon, considered the most beautiful time of the year to view it.
It is often thought to be eaten only during the moon viewing season in autumn in Japan, but many udon restaurants serve it all year round.
The egg’s preparation varies. While most just drop in a raw egg, others use an onsen tamago, and some use a fried egg.
How I Developed This Recipe
Ingredients and Substitution Ideas
- Udon Noodles: These thick wheat noodles have a wonderful chewy texture and are one of the most important elements of the dish. You can go for pre-boiled udon, dried udon, or frozen udon.
- Dashi Broth: This is the heart of our soup. Choose from my favorite dashi, simple awase dashi, or vegan dashi recipes. If you’re in a hurry, instant dashi granules or dashi packets work just fine.
- Soy Sauce: I’ve tried many, but for those looking for a reasonable option, Kikkoman soy sauce never disappoints. If you’re curious about choosing the right soy sauce, check out my comprehensive soy sauce guide.
- Mirin: When shopping, look for “hon mirin” for the best taste. I recommend Hinode Hon Mirin as a high-quality and affordable option. For more on Japanese condiments, you might like my post on the top 20 essentials.
- Salt: Regular sea salt works perfectly here.
- Egg: I usually use medium-sized eggs, but if you have small or large ones work too.
- Bacon: Fatty bacon from pork belly is my favorite. It adds that extra texture to the dish. I recommend unsmoked bacon so that the flavor is not too overpowering.
- Toppings: I used chopped green onions, kamaboko (Japanese fish cakes), and tenkasu (tempura flakes). Other topping ideas include shiitake mushrooms and mitsuba leaves to create a pine tree for a lookout or nori and wakame seaweed to create the night sky and mountains.

Here are my step-by-step instructions for how to make delicious tsukimi udon at home. For ingredient quantities and simplified instructions, scroll down for the printable recipe card below.
Add dashi, soy sauce and mirin to a saucepan and boil over a high heat for 1-2 minutes to burn off the alcohol in the mirin.
Turn off the heat and add salt. Mix until dissolved and leave on the warm stove for later. Reheat right before serving if necessary.
Heat a pan on medium and add the bacon. Fry until crispy on both sides.
Crack the eggs into the pan and fry sunny-side up style until cooked to your liking. If you don’t want the bacon to be cooked in the eggs, feel free to remove it from the pan before you add the eggs.
Once cooked, turn off the heat.
Cook the udon noodles according to the instructions on the packaging. Once cooked, pour through a sieve or colander to drain and rinse with fresh hot water to remove the excess starch.
Cut two slices of kamaboko per portion and cut along the bottom of the pink edge until the knife meets the center.
Place the flap down on the chopping board and cut it in half.
Fold them under so the edge is wedged in the middle.
Place a black sesame seed to make an eye, then dip a chopstick in ketchup and dab it under the eye to make a blushing cheek design.
The kamaboko rabbit is complete!
Divide the udon and broth evenly into serving bowls and top with two pieces of bacon, one egg, two kamaboko rabbits, chopped green onion and tenkasu.
It is not advisable to keep Tsukimi Udon after preparation, as leaving the noodles in the soup for too long can cause them to become soft and mushy.
However, it is possible to make the broth ahead of time and store it in the refrigerator for a week or freeze it for up to a month. If you choose to freeze it, it is recommended to divide it into smaller portions for easy thawing.
For the best texture, it is recommended to eat udon noodles immediately after cooking.
