Most traditional wheat pastas contain high amounts of carbohydrates, often exceeding 40 grams per cooked cup, which can be a hurdle for those following low-carb or ketogenic diets. Fortunately, a variety of alternatives are available that offer the flavor and texture of pasta with a significantly lower carb count. From virtually zero-carb options to nutrient-dense bean-based varieties, the best choice depends on your specific dietary needs and preferences.
The Absolute Lowest: Shirataki and Konjac Noodles
For anyone aiming for the lowest possible carbohydrate intake, shirataki noodles are the clear winner. Made from glucomannan, a fiber derived from the konjac yam root, these noodles are almost entirely water and fiber. This results in a product with negligible calories and, crucially, virtually zero net carbs per serving.
Shirataki noodles come packed in a liquid that has a distinct, sometimes off-putting odor, so proper preparation is key. Rinsing them thoroughly and then 'dry-frying' them in a pan without oil helps to remove the moisture and improve their texture, making them better at absorbing sauces. Due to their delicate and slightly rubbery consistency, they pair best with bold, flavorful sauces, such as curries or rich garlic-based sauces, that can stand up to the unique texture. Brands like Miracle Noodle and It's Skinny are popular choices in this category.
Next-Tier Low-Carb Alternatives
Hearts of palm pasta is another extremely low-carb option, typically offering only 2-4 grams of net carbs per serving. This alternative, made from the inner core of palm trees, has a flavor reminiscent of artichoke hearts, which some people enjoy and others find acidic or briny. Unlike shirataki, hearts of palm pasta has a softer, more substantial bite and can be used in a wider variety of dishes, from creamy sauces to layered lasagna.
For those who prefer a fresher, vegetable-based noodle, spiralized zucchini (often called 'zoodles') and spaghetti squash are excellent choices. Zoodles are simple to make and work well with lighter sauces like pesto, though they can release moisture during cooking and require patting dry. Spaghetti squash, which produces thin, noodle-like strands when roasted, offers a slightly sweet flavor that complements robust tomato sauces. Both are natural, whole-food alternatives with minimal carbs.
Legume-Based Pastas
For a boost of protein and fiber, edamame and black bean pastas are a popular choice. While not as low in carbs as shirataki or hearts of palm, they are still significantly lower than traditional wheat pasta, with net carb counts ranging from 4 to 8 grams per serving depending on the brand. Their nutritional benefits are substantial, providing a high protein content that promotes satiety. These pastas have a denser, more satisfying texture that stands up well to hearty sauces and can be a great option for those who miss the 'al dente' feel of traditional pasta.
Low-Carb Pasta Comparison Table
| Pasta Type | Net Carbs (per serving) | Texture | Best Paired With |
|---|---|---|---|

| Edamame/Black Bean | 4–8g | Chewy, dense, satisfying | Hearty tomato sauces, rich pestos |

| Traditional Wheat | ~42g | Firm, al dente | All sauces (for comparison) |
Choosing the Right Low-Carb Pasta for You
Selecting the ideal low-carb pasta depends on several factors, including your carb limit, flavor and texture preferences, and the specific dish you are making. If you are on a strict keto diet, shirataki or hearts of palm are the best fit. If you have a bit more flexibility and prioritize protein and fiber, a legume-based pasta might be more satisfying.
How Texture Impacts Your Choice
The distinct textures of low-carb pastas are a major differentiating factor. Shirataki's rubbery consistency can be off-putting to some, while the mild, vegetal flavor of hearts of palm is not for everyone. Legume pastas most closely mimic the feel of traditional pasta, offering a chewy and dense bite that can feel more familiar. For fresh flavor and a lighter feel, spiralized vegetables are an excellent alternative that adds extra vitamins to your meal.
Cooking Tips for Low-Carb Pasta
No matter which option you choose, here are a few tips for a successful low-carb pasta night:
- Rinse Shirataki thoroughly: This removes the packing liquid's odor. Dry-frying helps improve the texture.
- Pat vegetables dry: Excess moisture from zoodles or spaghetti squash can water down your sauce. Salting and then patting dry can help remove some of this liquid.
- Match sauce to pasta: Pair hearty, robust sauces with chewier, denser pastas. Use lighter, fresher sauces with more delicate alternatives.
- Check doneness carefully: Many of these alternatives cook much faster than traditional pasta, so avoid overcooking to prevent a mushy texture.
- Consider nutrient-dense options: If carb count is less of a concern than overall nutrition, opt for a legume-based pasta for a higher protein and fiber boost.
Conclusion: Making the Best Choice for Your Health
When it comes to answering the question, "Which pasta has the fewest carbs?" the definitive answer is shirataki noodles. However, the best option for you depends on a trade-off between the lowest carb count and a texture and flavor profile that you enjoy. For those following a strict keto diet, shirataki or hearts of palm are excellent choices. For those seeking higher protein and fiber, edamame and black bean pasta provide a nutritious middle ground. Ultimately, the variety of low-carb pastas available today ensures you can find a satisfying and healthy way to enjoy your favorite pasta dishes.
