Buta Udon is the ultimate bowl of comfort. With thick, chewy udon noodles, savory-sweet pork, and a light yet flavorful broth, this dish strikes the perfect balance between hearty and soothing. “Buta” means pork in Japanese, and in this dish, thinly sliced pork is cooked in a simple soy-based sauce that brings out its natural richness.
The beauty of Buta Udon lies in its simplicity. You don’t need a long list of ingredients, just quality ones. The base typically starts with dashi, a Japanese soup stock that brings a subtle umami depth. Add soy sauce, mirin, and a bit of sugar, and you’ve got a broth that’s savory, slightly sweet, and incredibly satisfying.
The pork used in Buta Udon is usually thinly sliced pork belly or shoulder. It cooks quickly and absorbs all the flavor of the broth. Some variations even include a quick marinade to give the meat an extra layer of taste. When paired with the udon noodles, which are delightfully thick and chewy, the textures in this dish become just as appealing as the flavors.
Toppings are kept minimal, just thinly sliced scallions, a soft-boiled egg, or a few pieces of nori. That way, the pork and noodles stay front and center. If you’re feeling adventurous, a pinch of shichimi togarashi (Japanese chili pepper blend) can add a gentle kick.
Buta Udon is great for weeknight dinners. It comes together quickly, especially if you use pre-cooked udon noodles, and it’s a complete meal in one bowl. It’s warm, filling, and has that nostalgic quality that makes you feel instantly at home.
Whether you’re new to Japanese cooking or just craving a cozy noodle dish, Buta Udon is a fantastic choice. It’s proof that with just a few ingredients and a little time, you can create something incredibly satisfying.

I don’t get why people love udon so much. This was just noodles in broth… not for me. 🤷
I totally get it! Udon can be pretty basic if you’re not into the broth. Maybe try a different dish next time? 🤷♂️
Sorry but this didn’t turn out good for me. The broth was too salty. Maybe I messed it up.
This udon recipe is fantastic! My family loved it and asked for seconds.
I used beef instead of pork since that’s what I had, and it still turned out quite tasty. Sake is weird tho.
Beef instead of pork? That doesn’t sound right. Udon is supposed to be with pork! 🤔
I think using beef is a cool twist! Sake can be strange, but it adds a unique flavor. Definitely trying it your way next time!
Yummm! So good and easy to make. My kids loved it. 💕
I’m glad to hear your kids enjoyed it! It’s a hit in our house too. 😊
Looks good but I don’t think my kids would eat pork. Can’t believe it’s that easy. 🤔
This recipe was amazing! The pork belly was so crispy and flavorful. Will definitely make again!
I thought it was too salty. Maybe less soy sauce next time?
Did you really need 300g of pork? Seems like a lot. Mine ended up too greasy. Maybe cut back on the meat?
Nori seaweed? I don’t even know what that is. Can I use lettuce instead?
This recipe is amazing! I added a bit of chili oil for a kick and it was perfect. My family loved it!
Eh, it was alright. I’ve had better ramen at a restaurant.
I think it sounds good! Sometimes homemade is better than restaurant food. Give it another try! 😊
Udon noodles are my favorite! This dish is so easy and quick. Thanks for sharing!
Yum! Would definitely cook again! Great dish for a cozy night.
Isn’t udon just noodles? You need more ingredients than that, right? 🤔
Actually, udon is definitely more than just noodles! It’s all about the broth and toppings too. This recipe looks pretty complete to me! 😊
Used beef instead of pork because that’s what I had. Still good!
This was amazing! The flavors were so rich and comforting. Will definitely make again!
Soo good! Best udon I ever made! 🤤 Can’t wait to make it again tomorrow!
Why is this called Buta Udon? Is Buta a type of noodle? Sounds weird.
It was okay, but I think I needed to add more seasoning. Just a bit bland for my taste.
The broth is soooo delicious! I could drink it! 🍜
Ew, pork belly? No thanks! I prefer chicken in udon.
Yum! Just what I needed for a cold night. I will definitely make this again!
Looks good but I’m not a fan of pork. Can I use chicken instead?
I’m glad you liked it! It’s perfect for those chilly evenings!
It was okay, but I found the broth too salty. Maybe reduce the soy sauce next time?
I messed up the noodles and they turned mushy. Not your fault tho! Lol.
My kids loved it! They usually don’t eat pork, but they ate it all up!! 😊
So easy to make! I added some veggies and it turned out great.
Sounds delicious! I love adding extra veggies too. What did you use?
I don’t know if it’s that easy… looks kinda complicated to me with all those steps.
I can’t believe how easy this was! I made it in less than 30 minutes. Yum!
So glad you loved it! It really is so quick and delicious. Did you add any veggies?
30 minutes? Really? I always thought udon was more complicated. Might have to try this now.
