How to Make Bone Broth Udon Soup

To make bone broth udon soup, you will need the following ingredients: chicken backbones or carcasses, ginger, garlic, bay leaf, peppercorns, scallions, fennel, onion, jalapeño (optional), and frozen udon noodles.

Ahead of time, you will need to make bone broth. For more in-depth info on bone broth, visit my post A Complete Bone Broth Guide.

To begin, add all your chicken bones, carcass, and vegetable ingredients to a stockpot, slow cooker, or Instant Pot.

Cover all the ingredients with water. Bring the water to a boil, then reduce until it’s lightly simmering. Cover with the lid of the stockpot and leave for 24-48 hours.

Now, using the broth that you made in advance, you can make the tasty udon noodle soup.

Cook your udon noodles in boiling water until tender (bear in mind the cooking time will be different depending on whether the udon noodles are dried, frozen, etc)

If you’re short on time and want to cook your noodles from frozen, there’s no need to defrost them first! Place the frozen noodles into boiling water and cook until tender, about 1 minute.

Once the noodles are ready, warm your bone broth, and pour 3 ladles of the broth into a bowl with your udon noodles. Top with the thinly sliced scallion & ginger, and any other ingredients you choose.
