Bone Broth Udon Soup

This hearty and delicious bone broth udon soup is an excellent way to use some freshly made homemade bone broth. With ginger, garlic, onion, and fennel, it’s a tasty and warming dish for any night of the week.

Is Udon Healthier than Ramen?

Udon noodles are thick, pale, wheat flour noodles often used in hot noodle soups. Ramen noodles are much thinner, yellow wheat noodles that are also used in soups, usually flavored with soy or miso.

As to which is healthier, it really depends on the preparation. Fresh udon noodle soup made at home will likely be healthier than store-bought ramen that’s packed with sodium and processed ingredients.

However, a homemade ramen dish where you know exactly what’s going into the recipe would be healthier than the store version. It really depends on the additions you make and how you cook them.

What is Udon Broth Made Of?

A simple and traditional udon broth is made of dashi broth, soy sauce, and mirin. It gives a mild, savory flavor. This recipe is made with bone broth, instead of the traditional dashi.

What is Dashi Broth Made Of?

Dashi broth is a Japanese broth used widely in soup recipes – for example, to make udon broth. Dashi is made from a combination of water, dried kelp, bonito fish flakes, dried anchovies and shiitake mushrooms. Most dashi broths will use water and two of the above ingredients. Dashi is a great base for noodle dishes and has that coveted umami flavor. It is also great in Agedashi Tofu, a Japanese favorite.

Do I Have to Eat Udon with Dashi Broth?

Traditional udon in udon broth requires dashi, but you can, of course, use udon noodles in many other recipes like this one. You can also substitute other types of noodles based on your personal preference.

How Do I Cook Udon?

To cook udon noodles, you will need to bring water to the boil and place the noodles in the water until submerged. Cook until they are tender but not too soft and slippery. The cooking time may vary depending on whether you are using semi-dried, dried noodles, or frozen udon. I prefer frozen udon noodles, which take 1 minute to cook.

How Do you Cook Frozen Udon Noodles?

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.

What Can I Add To Udon Soup?

In theory, you can add whatever you like to udon soup so that it’s just right for you. If you want to stick to traditional add-in ingredients, or are looking for inspiration, try any one of these:

• Roasted or sliced veggies like parsnips, sweet potato, or turnips
• Seaweed
• Furikake seasoning
• Soy sauce
• Chili oil
• Shichimi Togarashi
• A soft boiled egg
• Woody herbs like rosemary and thyme
• Meat additions like chicken or beef

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 for more info.

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

Cover all the ingredients with water. Bring the water to 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)

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