How Did Udon Noodles Originate?
Udon noodles are popular in Japanese cuisine, but they originated in China. They were introduced to Japan during the Tang dynasty era of 618-907 CE.
It is believed that when Udon noodles were first introduced, they were more like dumplings than noodles.
In fact, in some parts of Japan, they are still cut into squares as opposed to the long strands that became popular in the early fourteenth century.
Their original square shape may be part of why they are still relatively thick.
The popularity of the noodles really kicked off when they began to be sold in specialty stalls in the 17th century.

Are Udon Noodles Good for You?
Udon noodles are relatively high in calories but they contain complex carbohydrates that can be beneficial in controlling weight and reducing the risk of heart disease and type 2 diabetes.
They are also a good source of potassium, iron, thiamine, copper, riboflavin, copper, folate, and magnesium.
Here are some of the health benefits they provide.
Weight Loss and Chronic Disease Prevention
Udon noodles are complex carbohydrates and are therefore high in fiber and slow to digest.
Therefore, they help maintain a healthy weight which, in turn, is beneficial in preventing heart disease, diabetes and other conditions linked to obesity.
Easy to Digest
Udon noodles are easy to digest.
This may be due to the fact that they are kneaded in advance which helps the protein to combine with the starch molecules making them more readily available for digestion.
May Prevent Colon Cancer
Certain varieties of Udon noodles may contain a high fiber content that can minimize constipation.
They improve intestinal health and may minimize the risk of colon cancer.
Complex carbohydrates are said to eliminate stress.
And, because Udon noodles are such a comforting food to eat, you can bet they are ideal for minimizing anxiety.
Rich in B Vitamins
Udon noodles contain B vitamins including thiamine, niacin, riboflavin, and folate. These help the body convert carbs into energy.
Thiamine is great for stress reduction and it can also boost the immune system.
Niacin is good for circulation and reducing inflammation.
It also plays an important role in the production of hormones in the adrenal glands and throughout the body.
To make sure the noodles you are eating are as healthy as possible, look at the ingredients carefully.
Noodles made with whole wheat will have more fiber and greater health benefits.
Also, if the noodles are made with salt, opt for those made with sea salt. This will be preferable for those on a low sodium diet.
Dietary Restrictions: Are Udon Noodles Gluten-Free?
Udon is a vegetarian-friendly meal but its wheat flour content means it is not for gluten-free dieters.
However, there are Udon noodles made of rice flour, that make a good gluten-free option.
The noodles also contain a high amount of carbohydrates so they are not the best choice for those looking to control their blood sugar level and diabetics.
If this is the case, it’s best to enjoy Udon noodles in small portions.
What is the Difference Between Soba and Udon Noodles?
Soba noodles are another type of Japanese noodle.
They are similar to Udon noodles but there are a few notable differences.
Here’s how they compare.
- Udon noodles are made from wheat flour while soba noodles are made from buckwheat flour.
- Both come in gluten-free varieties.
- Soba noodles have a nutty flavor while Udon noodles have a neutral taste.
- Both can be served hot or cold.
- Udon noodles are thicker and chewier than Soba noodles.
- Both are rich in protein, fiber, and other nutrients but soba noodles have more protein and fiber than Udon noodles.
What is the Difference Between Ramen Noodles and Udon Noodles?
Ramen noodles and Udon noodles both make popular Japanese side dishes and main courses, but they are not the same.
Here are a few differences to look out for.

What’s the Difference Between Udon Noodles and Lo Mein?
Lo mein is commonly used in Chinese cuisine. Here is how these two Asian noodles compare.
- Lo mein is made with wheat, water and egg. Egg is the ingredient that sets lo mein apart.
- Because egg is added, lo mein tends to have a richer, sweeter taste.
- Lo mein is typically served hot.
- Egg noodles may have a yellow color due to the egg ingredient.
- Like udon noodles, egg noodles have high amounts of protein. They are also rich in amino acids and have a low glycemic index that makes them less likely to affect blood sugar than other pasta products. Therefore, they provide you with more sustained energy.
What is the Difference Between Udon Noodles and Wheat Noodles?
This one gets tricky.
The thing is, Udon noodles are wheat noodles but not all wheat noodles are Udon noodles.
Wheat noodles refer to any type of noodle made with wheat.
This includes Udon noodles, whole wheat noodles, and egg noodles that are made with wheat and egg.
Italian pasta is also made with wheat.
The key difference between Italian and Asian pasta is that Asian pasta is made by pulling and stretching the noodles whereas, Italian pasta is made by rolling and slicing the dough.
As a result, Asian noodles are lighter and springier than their Italian counterparts.
What’s the Difference Between Glass Noodles and Udon Noodles?
Glass noodles are also commonly used in Asian dishes.
Here are some of the ways they differ from Udon noodles.
- Glass noodles have a see-through appearance that differs from Udon’s thick white look.
- Glass noodles are unique in that they are not made from rice or wheat. Rather, they are made from other sorts of starches like mung beans, tapioca starch, or sweet potato starch.
- Like Udon noodles, glass noodles have a neutral taste.
- Glass noodles have a thin, threadlike texture.
- Glass noodles tend to be healthier than other types of noodles because they made from healthier starches. Their nutritional value varies depending on the type of starch they are made from. Glass noodles made from mung bean starch, for example, are a good source of choline which helps protect cell membrane structure.
- Glass noodles are thin and springy as opposed to Udon which have a thicker texture.
What is the Difference Between Rice Noodles and Udon Noodles?
Rice noodles are also often used in Japanese cuisine.
Here’s how they add up when compared to Udon.
- Rice noodles are made from rice flour and water whereas Udon noodles are made from wheat flour and water.
- Both have a neutral flavor.
- While Udon noodles can be gluten-free, rice noodles are naturally gluten-free.
- Rice noodles are flatter and softer than Udon.
- When rice noodles are made from brown rice, they have a higher protein and nutrient content than Udon.
- Rice noodles are usually eaten hot but they can be served cold as well.
What is the Difference Between Regular Noodles and Udon Noodles?
Regular noodles are typically used in Asian inspired dishes but can be used in just about any meal application.
Here’s how they compare to Udon noodles.
- Regular noodles are usually made from durum wheat, eggs, and water as compared to Udon noodles which are made from wheat flour.
- Regular noodles contain gluten.
- Both regular noodles and Udon noodles have a neutral flavor.
- Regular noodles are usually eaten hot but can be eaten cold.
- Regular noodles are usually enriched with vitamin B and iron. They do not contain as much protein as Udon noodles.
How Do You Eat Udon Soup?
It can be difficult to eat soup politely when at a restaurant.
It is recommended to use the spoon provided for the broth rather than drinking it directly from the bowl.
But when it comes to the noodles, feel free to slurp away.
Of course, this depends on where you are. While slurping may be considered rude in American restaurants, it is perfectly acceptable in Japan.
Do You Have to Boil Udon Noodles?
If udon noodles are soft and vacuum packed, they will not require any pre-cooking. You can just add them to your dish and heat them.
If the noodles are dried or semi-dried, you will need to boil them in water.
Dried noodles will need to boil for 10 minutes whereas semi-dried varieties need to boil for 8 minutes.
Do Udon Noodles Go Bad?
Dried Udon noodles can be stored for 6 to 8 months.
Fresh Udon noodles should be refrigerated and eaten within days.
Is Udon the New Food Trend?
Recently, noodle places have been trending in American culinary culture.
Ramen joints were on the rise for a while, but now it seems as if Udon is taking over!
Udon chains are exploding all over the place and many have lines of people out the door waiting for their meals.
This begs the question, why are Udon noodles so popular?
There are a few answers to this question.
For one, the elastic dough is difficult to make and its preparation takes an enormous effort. In fact, traditionally, the dough had to be kneaded with the chef’s feet in order to get to the desired consistency.
Today, machines can be used to get the dough prepared for cooking, but these machines are quite expensive and work hard to do their job.
The attention to detail pays off in a hearty and delicious meal.
And while the dough requires a lot of kneading, most kitchens have an easy set up that allows the food to be prepared quickly.
This typically consists of the noodle maker, a pot for boiling, an ice bath for blanching, simmering pots and a station with various kinds of toppings.
The end result is a fresh, affordable meal that can be made in just minutes. This makes it a great option for diners everywhere.
It is also appealing because it can be vegan and vegetarian friendly and it fits right in with the ‘bowl generation’ that is rising in the ranks when it comes to culinary preferences.
Udon has become so popular, it is edging out Ramen restaurants. This may be because it is a healthier option that appeals more to veggie-friendly sensibilities.
At the beginning of the article, we promised you that we would give you the information you need to discern an Udon noodle from any other noodle in front of you.
Did we do our job? And how will you be enjoying Udon the next time you decide to eat Japanese?
