Calorie breakdown by variation

Standard Udon Noodle Soup

Bonchon's standard Udon Noodle Soup is the baseline for calorie content. Typically, a serving contains around 430 calories. The nutritional profile for this version is largely composed of carbohydrates from the udon noodles and some protein, with minimal fat. It is often a good source of fiber, but the sodium content is notably high, exceeding a significant portion of the recommended daily value.

Udon Noodle Soup with Egg

Adding an egg to the udon soup increases both the calorie and protein count. The egg variation typically has around 500 to 580 calories per serving. This is a more balanced option, as the egg boosts the protein, making the meal more filling. However, the sodium level remains a key nutritional consideration, and some versions might have slightly more fat due to the egg yolk.

Udon Noodle Soup with Bulgogi

The bulgogi udon noodle soup is one of the highest-calorie options. The addition of marinated, thinly sliced beef adds both fat and protein, significantly elevating the calorie total. A serving of this hearty soup can be up to 660 calories or even higher, according to some reports. The higher calorie count is accompanied by a greater amount of fat and protein, alongside a very high sodium concentration.

Udon Noodle Soup with Seafood

For those who prefer seafood, this variation offers a significant protein boost while remaining more moderate in calories compared to the bulgogi version. A serving of seafood udon noodle soup has about 520 to 600 calories. It provides a good source of protein from the mixed seafood, but it still has a high sodium count and can contain cholesterol from the seafood.

What contributes to the calories?

Udon Noodles: The thick wheat-flour noodles are the primary source of carbohydrates and a significant contributor to the total calorie count.
Broth: The savory broth itself can contain calories from seasonings, oils, and other flavor enhancers.
Protein Additions: Optional ingredients like beef, seafood, or egg substantially increase the calorie count, as well as the protein and fat content.
Vegetables and Garnishes: While generally low in calories, vegetables like scallions or mushrooms contribute some calories and important nutrients.

How to make a more balanced choice

For those seeking a healthier or lower-calorie meal, consider these modifications when ordering:

Ask for extra vegetables: Increasing the vegetable content can add volume, fiber, and nutrients without a major calorie spike.
Consider a smaller portion: If available, opting for a smaller size can drastically reduce the overall calories and sodium.
Limit the broth: The broth is where most of the sodium resides. Consuming less of the broth can help manage sodium intake.
Customize your protein: Opt for the seafood or egg versions for a higher protein content relative to calories compared to the bulgogi option.
