With just thick udon and a clean dashi in the bowl, the broth's balance of soy, salt, and a whisper of sweetness is what you're really tasting. Once the soy goes in, keep the broth below a hard boil. Boiling it flattens the delicate dashi aroma the whole bowl is built around.

The Ingredients — and where to get them
Cook for2servings
Udon noodles
Thick wheat noodles with a springy chew are the centerpiece.
Can you make Udon Noodle Soup in an air fryer? — Yes, with an insert
Not on its own — an air fryer can’t hold a pool of liquid. You can simmer it in an oven-safe dish or a silicone insert made to fit the basket, but the broth won’t reduce or brown the way it does on the stove, and that insert comes out scorching, so use oven mitts. For real depth, a pot on the stove wins.
Can you freeze Udon Noodle Soup? — Yes
Yes — it freezes well. Cool it fully, portion into airtight containers, and it keeps a few months; thaw in the fridge and reheat gently.
Can you make Udon Noodle Soup ahead of time? — Best fresh
Best made fresh and served soon — it loses its edge standing around. You can prep the parts ahead, but finish and serve it close to the table.
Is Udon Noodle Soup gluten-free? — Not as written
Not as written — it contains gluten. Make it gluten-free: swap in a gluten-free pasta or noodle (check the other labels too).
Is Udon Noodle Soup vegan? — No
No — it contains seafood, so it isn’t vegetarian or vegan.
