Buta Udon

February 8, 2024

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.

  3. 4 stars
    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.

  4. User avatar freddie.bayer42 says:

    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. 🤷

    1. 4 stars
      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!

    1. 5 stars
      I totally agree! The pork belly just melts in your mouth. I love how simple yet flavorful this recipe is! 😍

    2. 3 stars
      Looks good, but not sure about the ratio of noodles to broth. Is 3 cups really enough?

  10. User avatar cecille.white says:

    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.

  12. User avatar terri.huel says:

    Too salty for my taste. The soy sauce really overpowered everything. I added some sugar to balance it out.

  13. User avatar stuart.trantow says:

    5 stars
    This looks so comforting. I love how the pork belly gets browned and then the soy-mirin-sake broth gives it that deep flavor.

  14. 4 stars
    I used beef instead of pork since that’s what I had, and it still turned out quite tasty. Sake is weird tho.

    1. 2 stars
      Beef instead of pork? That doesn’t sound right. Udon is supposed to be with pork! 🤔

    2. User avatar fermina.legros says:

      4 stars
      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! 🙌

  16. User avatar Galaxia Woonbeam says:

    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.

      Looks good but I don’t think my kids would eat pork. Can’t believe it’s that easy. 🤔

    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!

    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?

  27. User avatar Rosa Sisters says:

    I tried this and it didn’t turn out as expected. The noodles got all mushy. Maybe I overcooked them? 🤔

  28. User avatar edyth.cummings4 says:

    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.

  29. User avatar delphia.sawayn1983 says:

    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.

    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! 😊

  32. User avatar norman.schimmel says:

    I tried this and it was just okay. The broth was too salty for my taste. I’ll stick to my instant noodles.

    1. User avatar ernesto.rippin92 says:

      3 stars
      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!

    2. User avatar jackie.mertz says:

      4 stars
      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!

  33. User avatar louis.wuckert says:

    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!

  35. User avatar wilson.ward says:

    3 stars
    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.

  36. User avatar randall.gerhold36 says:

    4 stars
    Udon noodles can get mushy if you simmer too long. I only warmed mine for 2-3 minutes and it was perfect.

    1. User avatar rickiestmorty says:

      3 stars
      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?

    2. 5 stars
      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.

  37. User avatar sandie.mertz72 says:

    4 stars
    I used ramen noodles by accident once—still good, but definitely different. Udon makes the texture right.

    1. User avatar Draugr Overlord says:

      5 stars
      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 👌

  38. User avatar pierre.mosciski says:

    5 stars
    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.

  39. 3 stars
    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.

  40. User avatar amos.boyer41 says:

    4 stars
    Sake in the broth kinda worried me but it’s actually nice. If anyone skips it, I bet it’ll taste flatter.

  41. User avatar spencer.emmerich says:

    5 stars
    Yum! Would definitely cook again! Great dish for a cozy night.

  42. 2 stars
    Um, I thought udon has to be made fresh? Not sure if this is legit. 2 stars.

  43. 2 stars
    5 stars! no wait—actually 3? I messed up the sake and used what I had, but it was still edible. 😅

  44. 5 stars
    So easy to make! I had all the ingredients at home already. Definitely making this again!

    Isn’t udon just noodles? You need more ingredients than that, right? 🤔

    1. User avatar davis.erdman says:

      5 stars
      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!

    1. User avatar Boromir says:

      5 stars
      Yes!! Crispy pork belly + chewy udon is such a perfect combo. Extra green onions are a great call—makes it taste fresher.

    2. 4 stars
      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!

  48. User avatar darren.labadie2007 says:

    Used beef instead of pork because that’s what I had. Still good!

  49. User avatar walter.botsford says:

    Udon and pork… sounds good. rating: 5/5? idk 😅

  51. 2 stars
    why are we using nori on top… felt like fishy decoration lol. Flavor didn’t really pop for me, but it was filling.

  52. User avatar demarcus.reynolds0 says:

    3 stars
    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.

  53. 3 stars
    I think the soy sauce is too salty! Maybe reduce it next time?

  54. User avatar Candace Spencer says:

    4 stars
    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.

  55. 3 stars
    Isn’t udon noodles like spaghetti? I don’t get the hype. This had too much meat for me.

  56. User avatar porsha.feil says:

    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!

  58. User avatar mose.davis2024 says:

    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.

  60. 4 stars
    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!

  63. User avatar Noreen Farrell says:

    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! 🍜

  65. User avatar clyde.trantow75 says:

    The ingredient list is clear, but “browned and crispy” is vague—mine stayed kinda chewy. Next time I’ll cook the pork longer first.

  66. 4 stars
    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!

  67. 1 star
    Wow, what a mess! I burnt the pork and forgot to add nori. Don’t even know if it tasted good.

  68. 5 stars
    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.

    2. User avatar Effrafax of Wug says:

      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!
