You crave a hearty pasta bowl minus the post-meal carb crash. The picks here are all konjac-based (a root fiber that forms a filling, jelly-like noodle), and they deliver that familiar twirl-and-slurp experience with zero net carbs per serving. Here, we match the best zero carb pasta to your routine—quick lunches, keto dinners, or weekly meal prep.
I’m Mohammad — the founder and writer behind Calories Fit. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You will see that texture, odor, and prep effort separate the great from the merely good, and the zero carb pasta that wins is the one owners say tastes most like the real thing.
Our Picks at a Glance
How To Choose The Best Zero Carb Pasta
You want a pasta that won’t spike your carbs, and most zero carb options come from the konjac plant. Glucomannan, the root’s soluble fiber, creates the noodles’ signature springy texture. Since the base ingredient is similar across brands, your choice really depends on a few details that change how it feels and tastes in your mouth.
Check the smell and the prep steps
Konjac often carries a faint fishy or earthy odor right out of the package. Some brands work hard to remove it, while others need a thorough rinse (or even a quick boil and dry-fry) before the smell fades. If you are sensitive to smells, look for brands that explicitly say odor-free or read for owner notes about the rinse routine.
Match the noodle shape to your meal
Angel hair suits light broths, fettuccine and spaghetti handle thick sauces better, and penne or rice shapes work in stir-fries and bowls. A variety pack lets you test what you like before committing to a single shape, though you give up the consistency of a dedicated favorite.
Expect bland on its own, great with sauce
Konjac has almost no flavor of its own, which is exactly why it works as a pasta swap: it absorbs whatever sauce, seasoning, or broth you add. If you expect it to taste like wheat pasta on its own, you will be disappointed—buyers report the magic happens when you pair it with a bold sauce.

In‑Depth Reviews
1. Nashi Shirataki Konjac Fettuccine Noodles – Pack of 8
Our pick — 4.5★ from 150+ verified ratings; the strongest balance of quality and price.
The fettuccine that finally kills the fishy konjac reputation for good.
This is the pack that makes the whole zero-carb pasta idea feel less like a compromise. At just 8 calories per 100g, you get a hefty portion for practically nothing, and the fettuccine cut gives you that satisfying, ribbon-like bite that holds up instead of turning to mush. Owners mention using it in everything from Chinese soup to rich Italian-style sauces, and the recurring theme is that the texture stays firm and the noodles absorb whatever you put on them.
The standout is the odor control, which is the single biggest hurdle with konjac. Customers note these have none of the fishy scent that other brands carry, and even picky eaters have approved. The pack comes with 8 servings at 53.6 ounces total, so it is a bulk-friendly option that keeps a few dinners ready in the pantry. One owner even described the experience in the most direct way possible: “I love these noodles, I used them in my Chinese soup and they have no calories.”
Compared to the 52USA variety pack below, the Nashi is lighter at 3.53 pounds versus 3.3 pounds, but it wins on the fettuccine focus and the rave-worthy clean scent. It is a touch more premium in feel because the prep is simpler—open, rinse, heat, and serve without fighting a lingering aroma.
Why It Wins Dinner
- Firm, springy fettuccine that holds sauce without going mushy
- Zero fishy smell—the thing owners praise most
- 8 servings per pack for real weekly value
Who Should Look Elsewhere
- Only one shape (fettuccine) if you want variety
- Full 3.53-pound box takes up pantry space
Reach for this if: you want a reliable, odor-free konjac noodle in a classic fettuccine shape that you can toss with any sauce.
Consider otherwise: you want a mix of shapes rather than one dedicated noodle style.
2. 52USA USDA Organic Konjac Shirataki Noodle, 6 Pack 3 Variety
Three organic noodle shapes in one box for anyone who refuses to eat the same pasta twice.
If you are the type who gets bored eating the same shape every night, this 6-pack solves that with angel hair, fettuccine, and spaghetti in one order. The organic konjac base is a meaningful upgrade for buyers who care about sourcing, and the fact that it is sugar-free, soy-free, and fat-free checks every box a keto or paleo eater looks for. At 3.3 pounds for the whole pack, it is a solid pantry staple that covers soups, stir-fries, and classic spaghetti nights.
The thing everyone raves about is the taste—it is practically tasteless, which sounds like a criticism until you realize that is exactly what makes it work as a vehicle for sauce. Reviewers point out it has no weird taste, smell, or sourness, and it holds a firm, springy texture that works better in ramen or broth-based dishes than in heavy Italian recipes. One owner put it simply: “Super low carbs taste is pretty bland like any good pasta, the flavor for what you put on it mild texture. Easy to chew.”
Versatility is the headline here, and it beats the single-shape Nashi pack above if you want options without buying three separate boxes.
Best for the rotation: the 3-variety box means you never get stuck eating the same noodle all week, and the organic angle is a real differentiator. The honest caveat is texture—fans of ramen and soups will love it, while Italian purists may find it springier than expected.
3. DIET COOKER Premium Konjac Noodle, Angel Hair (6 Packs)
The budget-friendly angel hair that disappears into broth and lets the sauce star.
This pick suits the keto eater who wants a pasta fix without spending much, and it gives you a 0-calorie-per-serving noodle. The angel hair cut is delicate, so it works best in soups, broths, and stir-fries where it blends in, not in heavy casseroles where the texture stands out. It is free of gluten, fat, sugar, soy, corn, and egg, making it among the most allergy-friendly options here.
Prep is non-negotiable: shoppers say rinse thoroughly, though a faint fishy scent may linger during rinsing. One regular user described the routine: “You have to rinse well. They are a little small when rinsing, but it doesn’t carry over into the flavor. I use these a lot, but they are a little fishy smelling as you rinse them.” The good news is that the smell does not carry into the final dish, and once you add sauce, the noodles absorb the flavor well.
Compared to the pricier Keto Skinny pack below, this one costs less for the same 6-pack format and is a smarter entry point if you are new to konjac. The caveat is that the texture is the most-discussed downside—some owners find it rubbery, which is the trade-off you accept at this value tier.
Grab it for: quick keto lunches where the noodle is a backdrop, not the main event.
Think twice if: you are smell-sensitive—the rinse step really is non-negotiable here.
4. DIET COOKER Premium Konjac Noodles, Oat Spaghetti (Pack of 6)
The oat spaghetti that convinced a Miracle Noodle loyalist to switch for good.
For anyone who cut carbs years ago and remembers the miracle noodle craze, this is the budget-friendly upgrade. The oat spaghetti shape is made from konjac flour and oat fiber, delivering just 5 calories per serving and zero carbohydrates while keeping a familiar spaghetti silhouette that twirls around a fork like the real thing. It is ready to eat in minutes, which makes it a practical weeknight rescue when the pasta craving hits.
The interesting story here is the loyalty: buyers report coming back to this brand repeatedly over the course of a year, with several noting it beat the higher-priced miracle brand at roughly two-thirds the cost per bag. The preparation routine matters, though—owners find that boiling and then dry-frying after rinsing removes any residual odor and dramatically improves the texture. One keto dieter summed up the experience: “I love how the noodles don’t have a flavor. Easily used in any recipe that requires pasta. They are chewy, however worth the trade off for zero carbs.”
The trade-off is consistency—a few owners have noted that a batch can arrive clumped or tougher to chew than previous orders. That is the nature of a natural product, and it is worth knowing before you stock up entirely on this one brand.
The smart buy for: anyone who already knows they like konjac and wants a cheaper daily driver than premium brands. The chewy bite is the recurring note—expect it and you will not be disappointed.
5. Keto Skinny Variety Pack – Rice, Noodle, Penne (Pack of 6)
A full pantry reset in one box—rice, noodles, and penne for every kind of craving.
This pick is for meal preppers and keto dieters who want one order to cover breakfast, lunch, and dinner. The 6-pack includes 2 packs each of shirataki noodles, konjac rice, and konjac penne, all made from organic konjac flour, so you can stir-fry one night, make a rice bowl the next, and bake a penne dish after that. It is sugar-free, zero-carb, and paleo-friendly, a rare combo in one variety box.
The format is the real advantage—most brands lock you into one shape, but this one lets you test what you prefer before buying a full case of a single cut. Owners mention it is a quick fix when you want something that is not a vegetable, and a welcome break on a strict keto diet. As one owner put it: “Good alternative to pasta when you’re trying to lose weight.” The neutral taste is typical of konjac, and buyers advise adding soya or fish sauce to bring it to life.
The honest caveat is that a few owners have noted stomach upset when eating too much at once—konjac fiber is dense, so starting with a smaller portion is the smart approach. At 3.57 pounds, it is the heaviest box here, but you are getting three different formats in exchange for that bulk.
Choose this for: maximum variety in one order, especially if you are still figuring out which konjac format you actually love.
Be mindful if: your stomach is sensitive to high-fiber foods—portion control is the workaround.
Understanding the Specs
Net Carbs Per Serving
Net carbs are the keto dieter’s key metric, and all picks here hit zero. Zero carb pasta achieves its magic because the carbs come from glucomannan fiber, which your body does not digest like regular carbs. The key is checking the label for “net carbs”—total carbs minus fiber—and every pick here comes in at zero.
Calories and Fullness
Konjac is mostly water and fiber, which is why you see incredibly low calorie counts like 0 to 8 per serving. That fiber is also what makes you feel full, so a small portion goes a long way. The trade-off is that some people find the texture too chewy or springy compared to wheat pasta.
