Shirataki noodles are translucent, gelatinous Japanese noodles made from konjac root fiber and water, delivering roughly 7-20 calories per serving.
If you’ve been hunting for a pasta substitute that actually fits a strict calorie budget, shirataki noodles are the answer hiding in plain sight. These nearly calorie-free noodles, sometimes called konjac noodles or miracle noodles, replace wheat pasta with a chewy, translucent strand that absorbs the flavor of whatever sauce you pair it with. For calorie-smart eaters, they’re the rare food that delivers volume without the cost — and the nutrition profile backs up the hype.
The Nutrition Basics: What’s Actually Inside
Shirataki noodles are roughly 97% water and 3% glucomannan fiber, which explains their remarkably low calorie count. Glucomannan comes from the corm (root) of the konjac plant, a yam-like crop that’s been used in Japanese cooking for centuries. Because the noodles contain almost no digestible carbohydrate, protein, or fat, they’re a staple in low-carb and keto eating plans.
A typical serving lands between 7 calories per 100 grams and about 20 calories per 8-ounce serving. To put that in context, a standard 2-ounce serving of wheat pasta carries roughly 200 calories. You’re trading over 180 calories for the same fullness — a meaningful swap for anyone counting intake.
The noodles are naturally vegan and gluten-free. Their name comes from the Japanese word for “white waterfall,” a nod to their appearance. They carry almost no flavor of their own, which makes them a blank canvas for broths, sauces, and seasonings.
How Shirataki Noodles Compare To Regular Pasta
The trade-off for the low calorie count is texture and nutrition. Shirataki noodles have a firmer, slightly rubbery bite that some people love and others never warm to. They’re also not nutrient-dense — you’re trading pasta’s protein, B vitamins, and iron for nearly empty calories (which is the point, but worth knowing).
| Per Serving | Shirataki Noodles | Wheat Pasta |
|---|---|---|
| Calories | 7-20 | ~200 |
| Digestible carbs | ~0-3 g | ~42 g |
| Protein | Trace | ~7 g |
| Fiber | ~3 g glucomannan | ~2 g |
| Texture | Firm, gelatinous | Tender, chewy |
For most people, shirataki noodles work best as a vehicle for sauces rather than a straight 1:1 pasta swap. If you’re looking for a no-calorie noodle that handles a heavy ragu or stir-fry sauce without complaint, they deliver. Cleveland Clinic’s overview of shirataki benefits notes the noodles can help with satiety thanks to their fiber content.
Cooking Tips: How To Make Them Taste Good
Shirataki noodles arrive packaged in water and carry a faint, slightly fishy smell straight from the bag. Rinsing them well and dry-frying them resolves both issues. Here’s the method that works:
- Drain and rinse the noodles under cold water for 30-60 seconds.
- Boil them for 2-3 minutes to improve texture.
- Dry-fry in a hot pan for 3-5 minutes to remove excess moisture.
- Add your sauce and toss for 1-2 minutes until coated.
Because the noodles have almost no flavor, the sauce is everything. A bold marinara, a rich peanut sauce, or a garlicky butter base all work well. Skip thin broths unless you’re making a soup, where watery shirataki noodles fit right in.
One caution: glucomannan is concentrated fiber. If you’re not used to high-fiber foods, start with half a serving and drink plenty of water to avoid digestive discomfort.

FAQs
Are shirataki noodles actually good for weight loss?
They can help because they deliver volume and fiber for very few calories, which supports satiety. But weight loss still comes down to total calorie intake — shirataki noodles are a tool, not a magic fix. Pair them with lean protein and vegetables for a balanced meal that keeps you full.
Do shirataki noodles have any protein?
No, shirataki noodles contain essentially no protein — trace amounts at best. If you’re using them as a pasta substitute, add a protein source like chicken, tofu, shrimp, or edamame to the dish. Otherwise, a shirataki noodle meal may leave you hungry sooner than a higher-protein pasta dish would.
Are shirataki and konjac noodles the same thing?
Yes, the names are used interchangeably. Shirataki noodles are made from konjac root, and many brands label their products either way. Some products mix konjac flour with tofu or other ingredients, which changes the texture and adds a few calories, so check the label if the calorie count matters to you.
