How to Make Better Udon Noodle Soup at Home

The best noodle soup does not need dozens of ingredients. A few simple combinations can make a big difference.

Cook the noodles separately

Cooking udon separately helps you control its texture and keeps the broth from becoming unnecessarily starchy.

Add noodles near the end

Once the broth and toppings are ready, add the cooked udon for a short final simmer. This helps maintain its soft, chewy texture.

Build flavour in layers

Start with a broth, then add sauce, vegetables, protein, and finishing ingredients. Soy sauce, chilli oil, sesame oil, garlic, spring onions, and vinegar can each add a different layer of flavour.

Add protein for a complete meal

Egg, tofu, paneer, chicken, prawns, or mushrooms can turn a simple noodle soup into a more substantial bowl.

Use different sauces for different moods

Moi Soi Udon Noodles pair well with sauces including Hot Garlic, Schezwan, and Korean Gochujang, while the brand also recommends Korean Noodle Sauce and Chowmein Noodle Sauce for serving.

Why Udon Works So Well in Noodle Soup

Udon is a thick Japanese-style wheat noodle known for its soft and chewy texture. Its substantial shape makes it well suited to brothy dishes because it remains satisfying alongside vegetables, sauces, and proteins.

Moi Soi Udon Noodles are available in a 150 g pack and are positioned for soups, stir-fries, and cold noodle salads. The current cooking instructions recommend boiling them for 5 to 6 minutes while stirring occasionally before straining.
