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.

Sounds good, but I don’t love “cook udon in water then pour everything back.” Wouldn’t it get mushy? Also, what’s the point of sake if you can just use more mirin?
The broth combo (soy + mirin + sake) is classic Japanese cooking vibes. I added a pinch of sugar and it balanced perfectly for my taste.
Pretty solid. I had to add a splash more broth because mine was thicker than I expected, but the flavor balance is great. Next time I’ll thinly slice the pork even more for extra crisp.
Took a shortcut with thicker pork slices (didn’t crisp as much) but flavor still came out great. I’d maybe add a pinch of sugar next time to balance the soy.
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.
Finally, a recipe with no fish sauce! Easy to follow too. I added some chili flakes for a kick.
I used beef broth instead of chicken broth and it worked… kind of? The taste was different but still yummy. My friends liked it.
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?
Followed the steps and it came out pretty tasty. My broth tasted a little too salty at first, but once I balanced it, it was great.
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.
This looks so comforting. I love how the pork belly gets browned and then the soy-mirin-sake broth gives it that deep flavor.
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! 🙌
Not gonna lie, 3 cups broth feels like a lot for only 2 packs udon? I had extra liquid so I’ll reduce 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. 🤔
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.
Green onions + nori on top is such a vibe. I did the nori like a garnish like you said and it looked restaurant-y.
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 looks comforting and legit. I love the combo of mirin + sake in a broth like this—makes it taste way more “restaurant” than expected.
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!
Not gonna lie, I’m skeptical about cooking the udon in the broth at the end. Usually udon gets soggy fast. Still, the flavors should be decent—wish it said how long to simmer.
Udon noodles can get mushy if you simmer too long. I only warmed mine for 2-3 minutes and it was perfect.
Mine came out too soft last time, so I think you’re right about not simmering too long. But 2-3 minutes seems super short… do you mean like after adding them, or keep them in the pot on low the whole time?
Totally agree—udon turns to mush fast. I usually cook them separately and only simmer the noodles in the broth for a couple minutes too.
I used ramen noodles by accident once—still good, but definitely different. Udon makes the texture right.
I tried swapping in ramen once too—same vibe but way more slurpy than udon. Your point about udon texture is spot on. This recipe sounds legit, especially with pork belly crisping up 👌
Made this last night—so cozy. The pork belly gets that perfect crisp, and the broth tastes way more layered than I expected. I used regular udon and it still worked great.
Am I the only one who thinks 3 cups broth feels too much? Mine turned out kinda salty after the soy sauce—maybe my soy brand is stronger. Would reduce soy by like 1 tbsp next time.
Sake in the broth kinda worried me but it’s actually nice. If anyone skips it, I bet it’ll taste flatter.
Yum! Would definitely cook again! Great dish for a cozy night.
Um, I thought udon has to be made fresh? Not sure if this is legit. 2 stars.
5 stars! no wait—actually 3? I messed up the sake and used what I had, but it was still edible. 😅
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! 😊
This sounds super comforting. I love udon with pork belly—crispy edges are everything. Gonna try it with extra green onions!
Yes!! Crispy pork belly + chewy udon is such a perfect combo. Extra green onions are a great call—makes it taste fresher.
This looks really good, but do you think 3 cups broth is enough for 2 packs udon? Mine always drinks up the liquid, lol. Still gonna try though!
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!
Udon and pork… sounds good. rating: 5/5? idk 😅
why are we using nori on top… felt like fishy decoration lol. Flavor didn’t really pop for me, but it was filling.
Not bad! But I think 3 cups broth might be a lot or not enough depending on how many udon packs—mine was more like a stew.
I think the soy sauce is too salty! Maybe reduce it next time?
Garlic and onion step is key. I skipped chopping thinly once and it felt like the onion didn’t dissolve into the broth. Don’t be lazy like me.
Isn’t udon noodles like spaghetti? I don’t get the hype. This had too much meat for me.
I used beef instead of pork belly because that’s what I had. Still good, but the richness was different. Recipe is flexible, I guess.
Soo good! Best udon I ever made! 🤤 Can’t wait to make it again tomorrow!
My udon turned kinda mushy even though I cooked it according to the package… I think simmering it ‘a few more minutes’ overcooked it for me. Flavor was okay though.
Why is this called Buta Udon? Is Buta a type of noodle? Sounds weird.
Nori garnish?? Honestly that’s weird to me. But I tried it and it actually worked—like a salty ocean finish. Would make again.
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! 🍜
The ingredient list is clear, but “browned and crispy” is vague—mine stayed kinda chewy. Next time I’ll cook the pork longer first.
Made it tonight and it was good, but my pork belly didn’t get that “crispy” part—more like chewy. Think I needed higher heat or thinner slices. Sauce was still tasty though!
Wow, what a mess! I burnt the pork and forgot to add nori. Don’t even know if it tasted good.
5 stars!!! Also who decided nori on top is good? Cuz it is. My kids ate it and said it was “like warm noodles” lol.
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!
I followed it exactly and honestly it tastes better than it should for how easy it is. The broth is the star.
Yum! But I skipped the mirin and sake. Still tasted great! 🤤
Not bad but the instructions are kinda vague. “Cook until browned and crispy” like… how crispy? I guess I just went with my gut.
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. 😍
Not sure about using chicken broth with mirin and sake—feels a bit like mixing worlds. Still, the garlic/onion step smells amazing.
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.
I followed it mostly, but my broth tasted a little too salty. Next time I’ll reduce soy sauce or use low-sodium broth. Otherwise super easy.
Pretty solid. I had to add a bit more soy sauce because mine was a little bland, but overall it’s easy and hits the right comfort-food vibe. Would definitely make again.
Good to hear! I always end up tweaking the soy sauce too—depends on the brand and how salty the broth is. Glad it hit that comfort-food sweet spot 😄
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. 🙂
Looks easy. 5 stars.
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.
This looks super comforting—pork belly + udon is a combo I could eat every week. I might add mushrooms next time for extra depth.
Yes!! Pork belly udon is seriously the coziest. The mirin/sake combo makes it taste so “restaurant” to me. Mushrooms would be amazing too—try shiitake if you’ve got them.
Hmmm looks good but why chicken broth with pork belly? I’d think beef or pork broth. Also 2 packs udon seems like a lot—what size are your packs?
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.
