Quick & Easy Pork Belly Udon

This is a simple pork belly udon noodle soup that you can make at home, comprised of a sensational broth, crave-worthy vegetables and a soft cooked egg.

Pork Belly Udon Noodle Soup with a soft boiled egg, bok choi and fried mushroomsAlthough it bears no cultural relevance to me personally, udon noodle soup represents a significant touchstone of my childhood.

In my younger days, my parents would often take us to Happi House, a small Teriyaki chain in the Bay Area that served quick, affordable Japanese fare. Fast food, if you will, but a heck of a lot better for you than McDonald’s.

Back then I called it shoelace soup (remember I was like, seven).

I was always utterly mesmerized by those thick, dense, slippery noodles. And they still get me every time.

My absolute favorite of them all is pork belly udon noodle soup.

Why you need to try this Pork Belly Udon Noodle Soup: 

This is the quick, simple version that I now enjoy making at home- it’s comprised of a sensational broth that comes together in a flash along with all my favorite accompaniments:

  • Sumptuous pork belly (Trader Joe’s makes a fully cooked version that makes this recipe a breeze. Just sear and slice!)
  • A rich, silky soft-boiled egg
  • Earthy shiitake mushrooms
  • Crisp baby bok choy (make sure to toss in towards the end to maintain optimal crispness)
  • Fresh scallion- the perfect garnish

It’s certainly a more elevated version than the one I would have at Happi House, but it still takes minimal time to prepare, which is what I love about it the most (I mean, you know, besides those fat, glorious noodles).

Cook’s Tips for making Udon Noodle Soup: 

  • When searing the pork belly, make sure your pan is piping hot before you add the oil to it.
  • Ideally, you want fresh (not frozen) udon noodles for this recipe. Dried udon noodles are not recommended for this recipe (or any other recipe, really).
  • Fresh shiitake mushrooms offer a great texture, but you can also use dried sliced ones. They are actually much more flavorful. Remember to soak them in warm water for at least 20 minutes.

Variations on this recipe: 

  • If you want to go full-on Japanese, use dashi stock made from kombu and bonito flakes instead of chicken broth.
  • Enoki mushrooms are another great addition to this Udon Noodle Soup. They can be added within the last two minutes of cooking.
  • Use ramen or soba noodles if you can’t find udon noodles.

Can I use Soba or Ramen Noodles instead of Udon Noodles in this recipe?

Yes, you can use a different type of noodle for this pork belly udon noodle soup. Let me summarize the differences for you:

While Udon noodles are thick, quite pale and rather neutral tasting, Ramen are thinner noodles, also made from wheat, but with a slight golden color.

Both are mild in flavor and therefore often served in a hot flavor-intense broth.  You can easily swap one noodle for the other, adjusting the cooking time accordingly. Fresh ramen should cook within a minute, dried ramen slightly longer.

Soba noodles are made from buckwheat flour and have strong, nutty flavor. Many brands of buckwheat noodles have a small amount of wheat flour in them, which means they’re not gluten-free. However, pure gluten-free buckwheat soba can be found at Asian grocery stores.

Boil soba noodles for 5-7 minutes. Drain noodles and set aside, then add them to the soup along with the veggies.

  • 4 eggs
  • 6 ounces cooked pork belly I buy mine at Trader Joe's
  • 1 tablespoon vegetable oil
  • 1 teaspoon sesame oil
  • 2 cloves garlic minced
  • 1 inch piece fresh ginger minced

  • 8 ounces fresh udon noodles
  • 1 cup shiitake mushrooms sliced
  • 2 cups baby bok choy chopped
  • 1/2 cup scallions thinly sliced


  1. Place eggs in a medium-sized pot and cover with water. Bring to a boil over moderate heat, then turn off heat, cover pot and let eggs sit for about 4 minutes. Remove eggs from heat and transfer to a bowl of ice water to cool. Set aside.
  2. While eggs cook, add vegetable oil to a hot skillet and sear pork belly on all sides until a golden crust forms. Remove from skillet and slice thinly. Set aside.
  3. Heat a large soup pot over medium heat. Add sesame oil, garlic, ginger and chili garlic sauce and saute for 1-2 minutes. Add broth to pot along with soy sauce and rice vinegar. Bring to a simmer.
  4. Add noodles, mushrooms and the stalks of bok choy, reserving the leafy greens. Simmer gently for about 5 minutes. Taste and add more soy sauce if necessary.

      Yes, I think it would just have a more subtle flavor than the vinegar but it should work just fine!

    Excellent recipe! Found your site while searching for ways to use leftover pork belly – we love udon soups/shiitake/bokchoy etc. (husband is of Japanese heritage), so this sounded, & was, perfect. Came together quickly & is more filling than expected – no need for additional salad or side dishes. Quicker & sImpler than many Japanese-style dishes, but with full-on umami flavors. Used frozen udon & dried shiitake since that’s what was on hand & both worked out fine. Thanks – this will go into our regular rotation.

    Wow! This was just incredible. Thank you so much for putting this savory, delicious dish in my life! My husband and I could not stop raving about how good it was while we were eating it. I added like a teaspoon of chili flakes, just a little bit more sesame oil, and a carrot and half onion. SO GOOD!

    Did a small bone in pork roast in the instant pot. Kept the bone broth, cooled roast in fridge overnight. Made broth in instant pot by charring some onion then adding ginger, chili garlic sauce and garlic cloves. Added strained pork broth, water, a bullion cube and the other ingredients minus mushrooms and bok choy, added a carrot for a little sweetness, some dried seaweed and shaved bonito. Simmered on low 10 min. Served with sliced pork roast , fish cake, soft boiled egg, green onion, kimchi and udon noodles. Absolutely delish!
    Didn’t have bok choy or would have used it, and allergic to mushrooms so can’t go there. Didn’t have all the ingredients, but it worked. My Japanese spouse was very happy, and my kids loved it. Thanks for posting. Great recipe!
