As a noodle manufacturer, I heard the same question many times: "Do you have low-carb noodles?" Here's the truth that most people miss—noodles themselves aren't always the calorie bomb. A standard serving of plain wheat noodles runs about 220–280 calories. That's not nothing, but it's often the broth and toppings that turn your comforting bowl of noodles soup into a 600+ calorie meal.
If you're watching your weight or following a low carb food lifestyle, the real secret isn't just swapping out your noodles for low-calorie alternatives. It's building a flavorful, satisfying low carb soup base that keeps your taste buds happy without loading up on calories.
In this guide, I'll share four of my favorite low-calorie noodle soup broth recipes—each under 80 calories per serving—plus the best low-calorie sauces to amp up the flavor without derailing your diet.
Most home cooks obsess over the noodle type—whole wheat, rice, soba, konjac—but completely overlook what's in the bowl beneath them. A rich tonkotsu broth can easily pack 400–500 calories per cup, mostly from rendered pork fat. Cream-based soups like clam chowder or Alfredo-style broths are even heavier.
When you build your meal around a clear, aromatic low carb soup instead, you create room in your calorie budget for a satisfying portion of actual noodles. That means you don't have to eat sad, watery diet food. You just have to be smart about where the flavor comes from.
A winning low-calorie noodle broth has three qualities:
1. Umami depth without cream or oil – Build savoriness with mushrooms, seaweed, miso, or a long-simmered bone broth.
2. Aromatics over fat – Garlic, ginger, scallions, lemongrass, and fresh herbs deliver massive flavor for virtually zero calories.
3. Acid and heat – A splash of rice vinegar, lime juice, or chili paste brightens the palate and makes the soup feel more complex than it actually is.
With those principles in mind, here are four broth recipes you can whip up in under 20 minutes.
This is my go-to when I want something clean and restorative. It's the kind of low carb soup that feels like a detox without tasting like one.
Ingredients:
• a box of low-sodium chicken broth (Swanson Unsalted or Pacific Foods Low Sodium)
• 2 slices of fresh ginger
• 2 cloves garlic, smashed
• 1 stalk green onion, chopped
• 1 tsp low-sodium soy sauce
• Optional: a pinch of white pepper
Instructions:
1. Pour the chicken broth into a pot and bring to a gentle simmer.
2. Add ginger, garlic, and white pepper. Simmer for 10 minutes.
3. Remove ginger and garlic if you prefer a clearer broth.
4. Stir in soy sauce and green onions. Taste and adjust.
5. Pour over cooked noodles and serve immediately.
Pro tip: Add a handful of spinach or bok choy in the last minute for extra volume and nutrients without adding meaningful calories.
Miso paste is a powerhouse ingredient for low carb food. It's fermented, full of gut-friendly probiotics, and delivers deep umami with just a small amount.
Ingredients:
• 4 cups water
• 2 tbsp white miso paste
• 1/2 cup shiitake mushrooms, sliced
• 1/2 cup shredded carrots
• 1/2 cup baby spinach
• 1 tsp toasted sesame oil
• 1 tsp rice vinegar
Instructions:
1. Bring water or broth to a gentle simmer. Add mushrooms and carrots; cook 5 minutes.
2. Remove pot from heat. Place miso paste in a small bowl, ladle in some hot water, and whisk until smooth.
3. Stir the miso mixture back into the pot. Never boil miso—it kills the beneficial cultures and turns bitter.
4. Add spinach, sesame oil, and rice vinegar. Stir until spinach wilts.
5. Ladle over noodles and top with scallions.
Why it works: The mushrooms and miso create a savory, almost meaty depth that satisfies cravings for hearty noodle soup without any actual meat.
This one borrows flavors from Mexican sopa de fideo and Italian minestrone, but keeps the calorie count firmly in diet-friendly territory. It's proof that low carb soup doesn't have to be Asian-inspired.
Ingredients:
• 4 cups low-sodium chicken or vegetable broth
• 1/2 cup canned diced tomatoes (no salt added)
• 1/2 small onion, diced
• 1 clove garlic, minced
• 1/2 tsp dried oregano
• 1/2 tsp smoked paprika
• 1/4 tsp red pepper flakes (adjust to taste)
• Fresh basil leaves for garnish
Instructions:
1. Sauté onion and garlic in a non-stick pot with 1 tbsp water (or a quick spray of oil) until softened.
2. Add diced tomatoes, broth, oregano, paprika, and red pepper flakes.
3. Simmer for 15 minutes to let the flavors meld.
4. Taste and adjust seasoning. If it's too acidic, add a tiny pinch of sweetener or a splash of cream (optional, adds calories).
5. Pour over noodles and garnish with fresh basil.
Pairing suggestion: This broth loves whole wheat spaghetti or lentil pasta. The heartier texture stands up to the bold tomato and spice.
At just 25 calories per cup, this is the ultimate guilt-free noodles soup base. It's delicate, oceanic, and incredibly simple.
Ingredients:
• 4 cups water
• 1 piece dried kombu (about 4 inches)
• 1/2 cup dried bonito flakes (skip for vegetarian)
• 1/2 cup fresh shiitake mushrooms, sliced
• 1 tbsp low-sodium soy sauce
• 1 tsp mirin (optional)
Instructions:
1. Place kombu in water and let soak for 30 minutes (or up to overnight in the fridge).
2. Heat the water slowly. Just before it boils, remove the kombu.
3. Add bonito flakes, turn off heat, and let steep for 5 minutes. Strain.
4. Return the clear dashi to the pot. Add mushrooms and simmer 5 minutes.
5. Stir in soy sauce and mirin.
6. Serve over noodles with a sprinkle of sesame seeds and sliced scallions.
Note: If you want to keep it vegetarian, substitute dried shiitake for the bonito flakes. The flavor will be earthier rather than smoky, but still excellent.
As someone who makes noodles for a living, I can tell you this: the noodle is only half of the story. The broth is where the magic happens—and where the calories hide.
By mastering a few simple low carb soup bases, you can enjoy a generous, warming bowl of noodles soup any night of the week without stressing about your waistline. Whether you prefer the clean simplicity of a chicken and ginger broth or the oceanic depth of a mushroom dashi, there's a low carb food option here that will keep you coming back for more.
