Low-Carb Pasta Alternatives
For those managing their carbohydrate intake, whether for weight management, diabetes, or a ketogenic diet, traditional wheat pasta is often off the menu. Fortunately, the food industry has innovated, offering a variety of pasta alternatives with significantly lower carb counts. These alternatives are made from vegetables, plant fibers, and legumes, providing satisfying textures and flavors that complement sauces and other ingredients. Understanding the differences between these options is key to finding the best fit for your lifestyle and taste preferences.
Shirataki and Konjac Noodles: The Lowest-Carb Option
Shirataki noodles, also known as konjac noodles, are the undisputed champion of low-carb pasta. Made from glucomannan fiber derived from the konjac root, these translucent noodles are comprised of nearly 97% water and 3% fiber. A typical serving contains as little as 0–2 grams of net carbohydrates, making them ideal for strict ketogenic diets.
- Preparation: They are sold pre-cooked in water and require rinsing and draining before use. For best results, dry-fry them in a pan to improve their texture and reduce any residual odor.
- Texture: The texture is notably different from traditional pasta, often described as springy or slightly rubbery.
- Best for: They work best in dishes with strong, flavorful sauces, such as stir-fries, curries, or creamy Alfredo, which can mask their neutral taste.
Hearts of Palm Noodles
Hearts of palm noodles are another excellent low-carb choice. Made from the inner core of certain palm trees, these noodles offer a mild, slightly briny flavor similar to artichoke hearts. Hearts of palm pasta typically contains 2–4 grams of net carbs per serving, depending on the brand.
- Availability: They are usually found canned or in shelf-stable bags in the pasta or canned vegetable aisle.
- Texture: Their texture is softer than traditional pasta but holds its shape well, making it suitable for lasagnas or bakes.
- Best for: Hearts of palm pair well with pesto or rich, creamy sauces that complement its mild, acidic undertone.
Vegetable-Based Spirals
Vegetables like zucchini and spaghetti squash can be transformed into pasta-like strands, or “zoodles” and “squash noodles” respectively. These fresh alternatives are packed with nutrients and fiber, keeping the carb count exceptionally low.
- Zucchini Noodles: A cup of zucchini noodles contains only a few grams of net carbs and is easy to make at home with a spiralizer. The key is to manage their high water content by salting and draining them before cooking to prevent a watery sauce.
- Spaghetti Squash: This winter squash is roasted until tender, and the cooked flesh is then scraped out to form delicate strands. Its mild, slightly sweet flavor works well with hearty tomato sauces.
- Kelp Noodles: Made from edible seaweed, these noodles have a crunchy texture and are virtually carb-free. They require minimal preparation and are a great addition to salads.
Legume-Based Pastas
For those who prefer a texture closer to traditional pasta, legume-based options are a popular choice. While higher in carbs than shirataki or hearts of palm, they are also significantly higher in protein and fiber, offering a more satiating meal.
- Edamame and Soybean Pasta: Brands like Explore Cuisine create pasta from edamame and soybean flour, resulting in a product with a dense, chewy texture and a high protein content (24g per serving). Net carbs typically fall in the 4–6g range.
- Lupini Bean Pasta: This grain-free, keto-friendly option, famously from brands like Kaizen, offers an impressive 6g net carbs, 15g fiber, and 20g protein per serving. Its neutral flavor and classic texture make it a highly versatile substitute.
- Chickpea Pasta: While higher in carbs than other alternatives (around 32g total carbs), chickpea pasta is gluten-free and offers a good dose of protein and fiber. It's a stepping stone away from traditional pasta but not as low-carb as other alternatives.

Choosing the Right Low-Carb Pasta for You
The best low-carb pasta depends on your specific dietary requirements and culinary goals. If you are on a strict ketogenic diet and need the absolute lowest carb count, shirataki noodles are your best bet. Be prepared for a different texture, but embrace its versatility in dishes where the sauce is the star. For those who want a more familiar pasta-like texture without the high carbs, hearts of palm and lupini bean pastas are excellent choices. Hearts of palm are ready-to-eat and work beautifully in salads, while lupini pasta mimics the classic feel and can be used in almost any traditional recipe. Vegetable-based alternatives like zoodles and spaghetti squash are fantastic for adding nutrients and volume to a dish with minimal carbs, though they have a more distinct flavor and texture.

The wide array of low-carb pasta options available today means you don't have to give up your favorite pasta dishes. By experimenting with shirataki, hearts of palm, vegetable spirals, or high-fiber legume pastas, you can create delicious and satisfying meals that align with your health and wellness goals.

What is the difference between total carbs and net carbs on a low-carb pasta label?
Total carbs refers to all the carbohydrates in a product, including sugar, starches, and fiber. Net carbs are calculated by subtracting the fiber from the total carbs, representing the carbohydrates that are actually digested and converted to glucose by your body. Low-carb products, especially those high in fiber like konjac noodles, will often advertise their low net carb count.
How can I reduce the rubbery texture of shirataki noodles?
To improve the texture of shirataki noodles, rinse them thoroughly under cold water to remove the packaging odor. After rinsing, pat them dry and then dry-fry them in a pan over medium-high heat for several minutes before adding your sauce. This process helps evaporate excess moisture, resulting in a firmer, less rubbery texture.
Is lentil pasta a good low-carb choice?
While lentil pasta has fewer carbs than traditional wheat pasta, it is not as low-carb as options like shirataki or hearts of palm. It is, however, a great choice if you prioritize higher protein and fiber content over a super-low carb count, and if you enjoy a texture closer to conventional pasta.
How should I prepare zucchini noodles to avoid them becoming watery?
To prevent watery zucchini noodles, place the spiralized zoodles in a colander, sprinkle them with salt, and let them sit for 15-20 minutes. This draws out excess moisture. Afterwards, pat them dry with a paper towel before adding them to your sauce for a firmer result.
Can I freeze low-carb pasta alternatives?
It depends on the type. Vegetable-based options like zucchini noodles can be frozen, though their texture may soften upon thawing. Shirataki and hearts of palm pastas are typically sold pre-packaged and are shelf-stable or refrigerated, so freezing is not necessary. Homemade low-carb doughs, such as those made with almond or lupin flour, can often be frozen for later use.
Which low-carb pasta is best for a keto diet?
For a strict keto diet with minimal carb intake, shirataki noodles are the best choice as they offer a near-zero net carb count. Other options like hearts of palm pasta (2g net carbs) and lupini bean pasta (6g net carbs) are also excellent fits within a keto lifestyle.
Do low-carb pastas have a different flavor than regular pasta?
Yes, most low-carb pastas have a different flavor and texture profile than traditional pasta. Shirataki noodles are quite neutral, while hearts of palm can be slightly briny. Legume-based pastas may have a mild, earthy taste. Vegetable spirals will taste like the vegetables they are made from. The sauces you pair with them will play a big role in the final flavor of the dish.
