Understanding Net Carbs in Pasta
When evaluating which spaghetti has the least carbs, it is important to understand the concept of net carbs. Net carbs are calculated by subtracting the fiber content from the total carbohydrates. Fiber is a non-digestible carbohydrate, so it does not raise blood sugar levels in the same way that starches and sugars do. For this reason, many people on low-carb or ketogenic diets prioritize foods with a high fiber-to-carb ratio, which is exactly what many pasta alternatives offer. The key to finding a satisfying replacement is balancing your carb goals with your preferred texture and flavor.
The Lowest Carb Spaghetti Options
Shirataki (Konjac) Noodles
Shirataki noodles, derived from the konjac plant, are the undisputed champion for anyone seeking the absolute lowest carb spaghetti. These noodles are primarily composed of glucomannan, a soluble fiber, and water, resulting in an incredibly low-calorie and near-zero-carb food. A typical serving can have as little as 0-2 grams of net carbs. They are known for their gelatinous, slightly rubbery texture and neutral flavor, which allows them to absorb the taste of the sauces and ingredients they are cooked with. Rinsing and dry-frying them before adding sauce is highly recommended to improve the texture and remove any residual odor.
Zucchini Noodles (Zoodles)
Zucchini noodles, or "zoodles," are a fresh, vegetable-based alternative with a minimal carbohydrate content. Creating them with a spiralizer is simple, and they provide a great way to add more vegetables to your diet. One cup of zoodles contains approximately 2.4 grams of net carbs. Unlike traditional pasta, zoodles have a high water content. To prevent your final dish from becoming soggy, you can sauté them briefly or blot them dry with a paper towel after cooking. Their light, crisp texture makes them an excellent choice for fresh, vibrant sauces like pesto or a light marinara.
Hearts of Palm Pasta (e.g., Palmini)
Hearts of palm pasta, sold canned or in pouches, is another popular and very low-carb choice. Made from the inner core of the palm tree, it has a mild, slightly savory flavor and a texture that can mimic traditional pasta reasonably well. A serving often contains only 2-4 grams of net carbs. It is important to rinse this type of pasta thoroughly to remove the briny taste from the canning liquid. It pairs well with creamy or bold sauces that can complement its distinct profile.
Edamame Spaghetti
For those seeking a higher protein, plant-based option, edamame spaghetti is a great middle-ground choice. While not as low in net carbs as shirataki or hearts of palm, it still offers a significant reduction compared to regular pasta. A serving of edamame spaghetti typically has 4-6 grams of net carbs and a hearty dose of plant-based protein. It has a denser, chewier texture than wheat pasta and a slightly nutty, earthy flavor that pairs well with tomato-based sauces or pestos.
Spaghetti Squash
This is a natural, whole-food alternative to traditional pasta. When cooked and scraped, the flesh of the squash forms spaghetti-like strands. It has a naturally sweet flavor and a slightly firmer texture than typical noodles. While the exact carb count varies by size, it is a very low-carb option, making it suitable for many low-carb and keto diets.

How to Choose Your Best Low-Carb Spaghetti
Choosing the best low-carb spaghetti depends largely on your personal goals and taste preferences. If your primary objective is to achieve the lowest possible carb count, shirataki noodles are the clear winner. For those who prioritize a taste and texture closer to traditional pasta, hearts of palm or edamame spaghetti may be more satisfying. If you prefer a fresh, nutrient-dense meal and don't mind a different texture, zoodles or spaghetti squash are excellent choices.
Tips for a Successful Low-Carb Pasta Dish
- Rinse and Dry: For shirataki and hearts of palm, rinsing and drying is essential to remove packaging liquid and improve texture.
- Match the Sauce: A bold, flavorful sauce can enhance the taste of neutral-flavored options like shirataki or compensate for the natural flavors of vegetable-based pasta.
- Portion Control: Even with low-carb options, be mindful of your overall meal. Load up on protein and healthy fats to ensure you feel full and satisfied.
- Consider Cooking Methods: While some options like shirataki are pre-cooked, others like zoodles and spaghetti squash benefit from specific preparation methods to avoid excess moisture.
