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 Buta Udon recipe is amazing! The pork belly is sooo delicious, and everyone loved it!
I totally agree! The pork belly just melts in your mouth. I love how simple yet flavorful this recipe is! 😍
Looks good, but not sure about the ratio of noodles to broth. Is 3 cups really enough?
This udon recipe is fantastic! My family loved it and asked for seconds.
Too salty for my taste. The soy sauce really overpowered everything. I added some sugar to balance it out.
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!
Good eat. FAST. Thanks! 🙌
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. 🤔
My family loved this! It’s a total hit at dinner. Will make again! 🌟
I dunno, my friend made this and it was just kinda okay. Maybe I did something wrong? 🤔
So glad to hear your family enjoyed it! It’s one of my favorites too. 😊
Why isn’t there chicken in this chicken broth? 🤔
Just made this dish and my kids wouldn’t eat it. Probably my fault, I messed it up lol.
This recipe was amazing! The pork belly was so crispy and flavorful. Will definitely make again!
OMG! Did you guys add eggs too? I love udon with eggs! Must try next time! 🥚
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?
I tried this and it didn’t turn out as expected. The noodles got all mushy. Maybe I overcooked them? 🤔
I tried this with beef instead of pork, and it was still good. But why does it say to use pork? Just wondering if beef would be bad.
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! 😊
I tried this and it was just okay. The broth was too salty for my taste. I’ll stick to my instant noodles.
Really? I thought the broth was perfectly balanced! Maybe you should give it another shot, but with less salt? Can’t just keep eatin’ instant noodles forever!
I totally get that! I found it a bit salty too. Maybe you could try less soy sauce next time? Instant noodles are good when you’re in a rush though!
Could you make this recipe in a crockpot? I don’t wanna stand by the stove. Need easy meals.
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.
So easy to make! I had all the ingredients at home already. Definitely making this again!
This sounds delicious! I’m glad you found it easy. Can’t wait to try it myself!
Buta Udon? More like Buta YUM! Will def make again! 😍
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!
I think the soy sauce is too salty! Maybe reduce it next time?
Isn’t udon noodles like spaghetti? I don’t get the hype. This had too much meat for me.
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.
Excellent. Tasted better than takeout. My family loved it!
So good! This reminds me of my grandma’s cooking. mmm!
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! 🍜
Easy recipe! Thanks for sharing! Didnt realize udon was this simple to make!
You’re welcome! It’s awesome how easy it is, right? Udon is a game changer!
I dunno… looks a bit complicated with all the broth stuff. Can’t I just microwave udon?
Yummy! I added a boiled egg on top and it was delicious. My family loved it!
Ew, pork belly? No thanks! I prefer chicken in udon.
I don’t know if I did something wrong, but my noodles came out mushy. Maybe I overcooked them? Not sure if I will try again.
I dunno, noodles should be fine if you follow the instructions. Maybe you just left them in too long. Can’t believe you wanna quit!
Don’t give up! Maybe try checking the cooking time more closely next time. I’ve messed up noodles before too, and they turned out fine after a second attempt!
Yum! But I skipped the mirin and sake. Still tasted great! 🤤
This recipe is AMAZING! The pork belly is so crispy and the flavors are just right. Can’t wait to make it again! 😊
I totally agree! This recipe is so good! I’ve made it twice already, and it just gets better. 😍
Buta udon? Is that like a udon noodle in a cup? confused face emoji
No, buta udon is a kind of dish with udon noodles and pork. It’s not in a cup, but it’s super delicious!
Sounds yum! I thought it was a drink or something, haha. I’m gonna try this soon!
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!
I couldn’t find mirin and used honey instead, lol. It was not the same! Still, it was okay, I guess.
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.
Why do you use pork? Can I use chicken instead?
I dunno, I think pork gives it a unique flavor. Chicken will be different.
You can definitely use chicken instead! Just make sure to cook it well. 🙂
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.
This dish is sooo good! The pork belly adds a nice flavor. Highly recommend!
Good recipe, thanks! But I think too much onion. Made me cry and not in a good way😂.
Simple and quick! Loved how easy it was to follow. No fancy stuff, just good eatin’!
I found it kinda greasy tbh. Noodles were good but I think I’d skip the pork next time.
I kinda agree with you. The pork can be too much sometimes. But maybe try it baked next time? Less grease!
Greasy? Really? That’s how its supposed to be! Pork belly adds flavor! You can find it less oily if you just use less oil.
Yum! I love udon, but why do they call it Buta Udon? Is that like, a mistake? But tastes good anyway.
This was delicious! The pork belly was crispy and the broth was super flavorful. Will definitely make again!
So glad you liked it! The crispy pork belly really makes it special. Next time, try adding some chili flakes for a kick!
I don’t know, sounds a bit too simple for me. Like, can it really be that flavorful without some more spices or something?
I tried this recipe and it was just okay. The noodles were mushy. Not my best attempt.
I always thought sushi was the only good thing from Japan, but this udon is a game changer! Who knew? 🙂
Yum! Just used whatever I had in the fridge and it still turned out great. Gotta love cooking!
Udon noodles? Yuck! I don’t know why people eat these things, they’re too chewy for my taste. Not doing this again.
I totally disagree! Udon is one of my faves! Chewy is just how they’re supposed to be! Give it another try!
Not sure about the mirin part, what is that? Can I use something else? 🤔
This recipe is fantastic! My whole family loved it. The flavors are just amazing! Definitely a 5-star dish.
Buta what? I don’t know if this is a real dish but looks cool I guess. 🤔
I don’t know why everyone loves this, it’s kinda bland. Where’s the flavor? 1 out of 5.
So good!!! I didn’t have sake, so I used apple juice. Still turned out great! 🥳
Simple and quick! Loved how I didn’t have to chop much. Will definitely make again. Thanks!
This recipe is amazing! The pork belly gave it such a rich flavor. Definitely a 5-star dish!
Eh, I don’t know. Sounds too oily for my taste. Can I leave out the pork? 🥴
I totally forgot to add the nori part. What’s nori anyway? Is it important?
Easy peasy! I didn’t have chicken broth and used water. Seemed fine. Do I get a medal? 😂
