Ramen is a popular Japanese noodle soup dish that has gained popularity worldwide. Tonkotsu ramen is a specific type of ramen that is made with a pork bone broth, giving it a rich, creamy, and hearty flavor. But with its noodle, broth, meat, and topping ingredients, many people wonder just how many calories are in a bowl of tonkotsu ramen.
What is Tonkotsu Ramen?
Tonkotsu ramen gets its name from its broth, which is made by simmering pork bones for many hours to extract the collagen, fat, and nutrients. This gives the broth a cloudy, white, creamy consistency unlike other lighter ramen broths. Tonkotsu broth is valued for its rich, hearty, and comforting flavor.
Authentic tonkotsu ramen usually contains the following basic components:
- Tonkotsu broth – thick, creamy, pork bone broth
- Ramen noodles – wheat noodles, typically straight and thin
- Pork belly – sliced braised or roasted pork belly chashu
- Aroma oil – flavored oil added to the broth
- Toppings – sliced green onions, dried bamboo shoots, boiled egg, etc.
Additional toppings can include black garlic oil, sesame seeds, butter, bean sprouts, and more. The rich broth paired with thin noodles and savory toppings makes tonkotsu ramen a hearty, comforting, and delicious noodle soup.
Calories in Tonkotsu Ramen Components
To determine how many calories are in a bowl of tonkotsu ramen, we need to look at the calorie content of each component:
Tonkotsu Broth
The tonkotsu broth is the foundation of the dish. Pork bones are simmered for many hours to extract the fat, collagen, marrow, and nutrients to create the creamy broth. A 1 cup serving of pork broth contains:
- 71 calories
- 4.5 g fat
- 0 g carbs
- 6 g protein
However, tonkotsu broth is richer than plain pork broth due to the emulsified fat and collagen, so a cup likely contains 100-150 calories.
Noodles
Ramen noodles are typically made from wheat flour, water, salt, and kansui (alkaline mineral water). A standard ramen serving contains around 200g of noodles. 200g of plain wheat noodles contains:
- 220 calories
- 0.4 g fat
- 46 g carbs
- 8 g protein
Pork Belly Chashu
Sliced, braised, or roasted pork belly chashu is a key component adding flavor and texture. A 100g serving of pork belly contains:
- 420 calories
- 45 g fat
- 0 g carbs
- 15 g protein
So a typical 50g portion of pork belly would add 210 calories.
Aroma Oil
Aroma oils are added to tonkotsu ramen to enhance flavor. These are typically made from garlic, chili, or sesame oil. One tablespoon of sesame oil contains:
- 120 calories
- 14 g fat
- 0 g net carbs
- 0 g protein
So a typical teaspoon of aroma oil adds around 40 calories.
Vegetable Toppings
Typical vegetable toppings include sliced scallions, spinach, nori, bamboo shoots, bean sprouts and more. These provide nutrients but are low in calories. We can estimate around 30 calories total for 1/2 cup of assorted vegetable toppings.
Egg
A soft boiled egg is often added to tonkotsu ramen. One large egg contains:
- 78 calories
- 5 g fat
- 0.6 g carbs
- 6 g protein
Total Calories in Tonkotsu Ramen
Adding up the average calorie counts for each component, we can estimate the total calories in a bowl of tonkotsu ramen:
| Component | Calories |
|---|---|
| Tonkotsu Broth (1 cup) | 100 |
| Noodles (200g) | 220 |
| Pork Belly Chashu (50g) | 210 |
| Aroma Oil (1 tsp) | 40 |
| Vegetable Toppings (1/2 cup) | 30 |
| Egg (1 large) | 78 |
| Total Calories | 678 |
So in total, a typical bowl of tonkotsu ramen contains around 678 calories. However, this can vary depending on the portion sizes, ingredients, and recipes used.
Ways to Reduce Calories in Tonkotsu Ramen
While tonkotsu ramen is a high calorie dish, there are some ways you can tweak it to reduce the calories if you want a lighter meal:
- Use reduced sodium broth – Tonkotsu broth is high in fat from pork bones. Opting for a low sodium broth cuts some fat.
- Reduce noodle portion – Cut back on noodles to reduce carbs/calories.
- Choose leaner protein – Chicken or shrimp instead of fatty pork belly.
- Load up on veggies – Fill up on negative calorie toppings like bean sprouts.
- Skip the egg yolk – Egg white only removes fat/cholesterol.
- Easy on aroma oils – They add lots of flavor but also calories.
- Request low-cal dressing – e.g. vinegar, mustard, chili sauce.
- Drink water – Hydrate with water instead of high-cal beverages.
With some simple substitutions and reductions, you can shave off a couple hundred calories from a tonkotsu ramen. But keep in mind, altering it too much affects the signature creamy, rich broth.
Health Impact of Tonkotsu Ramen Calories
