An easy Udon Noodle Soup that's light, refreshing and packed with flavour. It makes a perfect low maintenance mid-week meal & once you've made that flavoursome broth you can really get creative with the toppings!
This Udon Noodle Soup wasn't intended to be shared here. It was just a super quick, mid-week dinner for us, which I happened to share on an Instagram story. I got so many messages asking for the recipe, that here we are......The soup's comin' atcha!

It's a bit of a soup meets salad kind of recipe. Sound weird? Well yes I guess it does, but it tastes amazing and is so fresh and healthy thanks to the mainly raw toppings.
What ingredients do I need?
(For detailed measurements and instructions, see the printable recipe card).
This soup features a warm, fragrant broth with thick, hearty udon noodles, then the toppings happen. I've used sautéed mushrooms, raw carrot matchsticks, green onion, jalapeños, fresh mint and sesame seeds but you can use whatever you have in your fridge.
It's a super easy soup to make, and although it does have a couple of exotic(ish) ingredients they are easy to find in just about any grocery store.
First, there is the beautifully fragrant star anise. You will find star anise with the spices in the grocery store. They look like pretty little stars (you can see a couple next to the bowl in the pic above) and they add such a lovely flavour to this broth.
Secondly, there is fresh lemon grass. You will find that in the produce section. It's usually near the chilis or fresh herbs. It has a subtle citrus flavour and adds a lovely bit of gentle, fragrant zip to the broth.
And lastly, there are the udon noodles. They are a really thick, Japanese noodle made with wheat flour. They tend to be available in fresh, frozen or dried form. Here, I usually find them in the freezer department. Any kind will do though. Just be sure to cook them as directed on the package.
If you can't find udon noodles, any noodles will work as a substitute in this recipe. Rice noodles would work particularly well, especially if you need to keep the recipe gluten-free.
How to make Udon Noodle Soup
This Udon Noodle Soup is made in just a few easy steps.
Step 1 - Make the broth by sautéing the onions, garlic and ginger. Then add the cinnamon, lemongrass and star anise, followed by the stock and tamari. Then simmer for 30 minutes to get those yummy flavours to shine.
Step 2 - Chop the vegetable toppings
Step 3 - Cook the noodles and drain.
Step 4 - Sauté the mushrooms
Step 5 - Assemble the bowls
Meal prep tips
Once you have made the broth it will keep in the fridge for up a week and it freezes well too. It's perfect for keeping on hand to make really quick and easy lunches or dinners throughout the week. Just cook some noodles, pour over the broth and top with whatever you've got in the fridge.
Topping ideas
Feel free to switch up the toppings that are included in this recipe. Anything goes so use whatever you have in the fridge.
Some other additions that would work well are:
- tofu
- cilantro
- lime
- peanuts
- bean sprouts
- thai basil
- greens like bok choy, chard, or napa cabbage (wilted slightly in the broth before serving)
- hot sauce
- baked tofu
It can become a wonderful way to use up the sad veggies in the fridge at the end of the week, so get creative!
It can also be really fun to have all of the toppings prepared and in bowls on the table. That way everybody can help themselves and customize their own soup with whatever toppings they like best.
To make it more appealing to children have some kid friendly veggies like peas and sweetcorn for them to put in their bowls.

📖 Recipe
Udon Noodle Soup
Author:Ingredients
- 4 teaspoons toasted sesame oil , OPTIONAL
- 1 medium onion , chopped
- 1 thumb sized piece fresh ginger , chopped
- 4 cloves garlic , chopped
- ¼ teaspoon ground cinnamon , or 1 cinnamon stick (added whole)
- 2 sticks lemon grass
- 2 - 4 star anise , 2 gives a very subtle flavour, 4 will make it more pronounced
- 8 cups / 2 litres flavourful stock/ broth , I highly recommend Pacific Natural Foods Mushroom Broth
- 60mls / ¼ cup tamari or soy sauce
- 800 grams udon noodles , or any other kind of noodle (rice noodles are great if you need to keep the recipe gluten-free)
Toppings (quantities are just a guide. Use as much or as little of each as you like and feel free to add any extras. See my list of topping ideas in my post above.
- around 300 grams / 4 cups sliced mushrooms , sliced
- 2 medium carrots , julienned (cut into thin matchsticks)
- 2 jalapenos sliced into thin rounds
- 1 bunch green onions , chopped into rounds
- 1 sprig fresh mint for each bowl , cilantro works well too
- sesame seeds for sprinkling , OPTIONAL
INSTRUCTIONS
- Warm a large pan over a medium heat and add 2 teaspoons sesame oil (to make oil-free sauté in a few tablespoons of water instead, adding more throughout as needed to stop sticking).
- Sauté the onions and ginger together until the onion is beginning to caramelize, then add the garlic and cook, stirring frequently, for another few minutes.
- Slit the lemon grass lengthways with a sharp knife then bash it with a rolling pin (it helps the flavour come out!). Add it to the pan with the the star anise and cinnamon then pour over the broth and tamari/soy sauce.
- Simmer for around 30 minutes then sieve it to remove all of the add-ins and return the liquid to the pan. Keep it on a low heat to keep warm.
- While the broth is simmering prepare your toppings. Wash and chop all of the raw veggies and sauté the mushrooms in the remaining 2 teaspoons of sesame oil until golden brown. Use water to sauté them to make oil-free. Once golden, remove from the heat and set aside.
- Bring a large pan of water to a rolling boil and cook the noodles as per the directions on the packet. When cooked, drain and rinse in cold water to stop them cooking any more.
- Assemble your bowls by putting noodles in the bottom, ladling over the hot broth, then covering with toppings of choice. Finish with an optional sprinkling of sesame seeds.

I made this recipe this evening and Was so looking forward to t being so yummy. The cinnamon overpowered the dish. I think using less cinnamon or just leaving it out completely would of made the soup turn out delicious. ?

Anita L Burkam says
I made this--absolutely stellar. Going to make some more this week. It's especially nice to make the broth ahead and then just cook the noodles and assemble the soup when you want a quick, tasty meal. I add bean sprouts for texture and tofu for protein. The fresh herbs really elevate this from tasty to divine.
