Kelp noodles substitutes

A crisp white root that keeps its crunch even in a hot pan, which almost no vegetable does.

Best for

cold sesame noodle salads, pad thai style dishes, slaws, spring roll fillings, stir-fries

This is the best texture match available, because jicama has the same stubborn snap that kelp noodles do and does not go limp with heat. What changes is the flavor: jicama is faintly sweet and apple-like where kelp noodles are almost flavorless with a whisper of the sea, so a peanut or sesame dressing tastes a touch sweeter and fresher. It has a few grams of carbohydrate per cup rather than none, and it needs peeling with a knife because the skin is tough.

Konjac noodles, the other translucent zero-carb noodle, and the easiest to find.

Best for

brothy noodle soups, stir-fries, very low-carb meals, Asian noodle bowls

Same job, same nutrition, different bite. Shirataki are springy, slippery and slightly rubbery, and they yield when you chew, whereas kelp noodles resist and crunch. Both come packed in liquid that needs a thorough rinse. The step that transforms shirataki is dry-frying: two to three minutes in a hot dry pan until they squeak drives off water and firms them up considerably, getting them closer to kelp noodles than you would expect from the bag.

Long white radish, crunchy and juicy, and the cheapest crunch substitute.

Best for

Asian noodle salads, kimchi-style dishes, cold dressed noodles, soups

The strands are crisp and watery, close to kelp noodles in look and reasonably close in snap. The difference is a clear peppery, faintly sulfurous radish bite that kelp noodles do not have at all, so a delicate sesame dressing gets pushed around by it. Salting the strands for ten minutes and rinsing them tames most of that. Cooked briefly it softens and sweetens; cooked long it turns limp and smells strongly of radish.

Crisp, watery raw strands for chilled bowls.

Best for

cold peanut noodles, summer salads, poke bowls, no-cook meals

For a cold dressed dish this is a genuinely good swap, crisp and refreshing with a clean grassy flavor instead of kelp's mineral note. It is much wetter, so it dilutes a dressing within about twenty minutes, which means dressing at the table rather than in advance. It cannot go anywhere near heat, since it collapses into liquid almost instantly. Use Persian or English cucumbers and scrape out the seeds first.

Mung bean or sweet potato starch noodles, the traditional clear noodle kelp noodles are imitating.

Best for

japchae, noodle soups, spring rolls, Thai and Vietnamese salads

Visually the closest of all, since both are transparent and slippery. Glass noodles are chewy and bouncy rather than crunchy, and they soak up dressing and broth greedily, so a dish made with them tastes more strongly seasoned than the same dish with kelp noodles, which absorb almost nothing. The trade-off is real carbohydrate, since these are pure starch, so they are not a low-carb option at all.

The most widely available vegetable noodle, softer and much more neutral.

Best for

warm noodle dishes, pesto, tomato sauces, quick weeknight meals

Easy to make and nearly flavorless, which matches kelp noodles, but the texture is the opposite: soft and tender within a couple of minutes of heat, with no crunch at all. Zucchini also releases a lot of water, so unlike kelp noodles it will thin your sauce. Salt and drain the strands for fifteen minutes first and cook them for no more than two minutes.

The pantry answer when you have no gadget and no specialty noodle.

Best for

slaw-style noodle bowls, stir-fries, budget meals, meal prep

Cabbage sliced very fine gives real crunch and holds dressing well for days without going soggy, which kelp noodles also do. It looks nothing like a noodle and tastes clearly of cabbage, sweet and sulfurous, so this works in a peanut or gochujang dressing and less well in a clear broth. Napa cabbage is milder and more tender than green cabbage if the flavor bothers you.
