Quick Summary tl;dr
Traditional sushi is built around seasoned rice — and that’s where the carbs add up quickly.
If you’re eating keto or low-carb, it’s easier to replace the rice than to try to “fit it in.”
Sashimi, nori rolls without rice, cauliflower rice, cucumber wraps, egg wraps, and even smoked salmon all work as solid alternatives.
Focus on protein, healthy fats, and simple fillings. Skip sweet sauces and check labels on imitation crab and pickled ginger.
Resistant starch may slightly lower rice’s blood sugar impact, but it doesn’t make rice low-carb.
Sushi was one of the last things I wanted to give up when I cut back on carbs.
It always felt like the “healthy” choice — fresh fish, seaweed, a little avocado. But once I actually paid attention to what was underneath it all, I realized most of what I was eating was sweetened white rice.
If you’re eating low-carb or keto, that rice adds up fast. A few rolls can wipe out your carb budget for the day without even trying. And if you’ve seen how the old food pyramid is finally getting flipped on its head — like in these new real food guidelines — it’s hard to justify rice as the foundation of the meal anyway.
But here’s what I learned pretty quickly: sushi isn’t really about the rice. It’s about the texture. The contrast between cool fish, avocado, salty soy sauce, maybe a little heat from wasabi. The rice just happens to be the delivery system.
Once I stopped focusing on “how do I make keto rice taste like rice?” and started asking “what actually makes sushi good?” everything got easier.
And yes — you can absolutely keep sushi on the menu. You just build it differently.
Can You Eat Sushi on Keto?
Short answer: yes — but not the traditional rice-heavy rolls most restaurants serve.
You don’t have to give up sushi altogether when you go low-carb. What you do need to rethink is the base of the roll. In most sushi, rice makes up the bulk of what you’re eating, and that’s where the carb count climbs quickly.
What Actually Makes Sushi “Sushi”?
Most people assume sushi means raw fish. It doesn’t. Technically, sushi refers to the seasoned rice — slightly sweet, slightly tangy, and sticky enough to hold everything together. The fish or seafood is the topping.
That’s why sashimi isn’t considered sushi at all. It skips the rice completely. And if rice is the defining ingredient — and rice is the carb problem — then that’s the part that needs replacing.
Why Rice Doesn’t Work on Keto
A typical serving of sushi rice can contain 20 to 40 grams of carbs. That’s before sauces, imitation crab, or anything sweetened gets added.
If you’re trying to stay in ketosis or simply keep your blood sugar steady, that amount adds up fast. Rice digests quickly, raises blood sugar, and doesn’t keep you full for long — especially compared to meals built around protein and healthy fats.
This doesn’t make rice “bad.” It just makes it a poor fit for a keto or low-carb approach.
And while we’re on the topic, rice can contain varying levels of inorganic arsenic depending on where it’s grown. Concerns about this have been highlighted by organizations such as the U.S. Food and Drug Administration (FDA) and the World Health Organization (WHO). It’s not something to panic over if you eat rice occasionally, but if rice is a daily staple, it’s another reason some people choose to limit it.
8 Rice-Free Sushi Alternatives
Once you stop trying to make rice fit into a low-carb diet, sushi gets much easier. The goal isn’t to perfectly recreate traditional sushi rice — it’s to keep the balance of flavor and texture that makes sushi good in the first place.
Some of these options are lighter and simpler. Others are closer to traditional sushi. All of them work without the carb overload.
1. Sashimi
If you want the simplest and cleanest option, sashimi is it. It’s just sliced raw fish — no rice, no fillers — and naturally very low in carbs.
Salmon, tuna, mackerel, and yellowtail are all great choices. Pair them with soy sauce or tamari, a little wasabi, and sugar-free pickled ginger. When you’re eating out, this is usually the easiest keto-friendly order.
2. Nori-Wrapped Rolls (No Rice)
Instead of replacing rice, you can skip it entirely. Lay out a nori sheet and layer sliced sashimi, smoked salmon, avocado, cucumber, or cooked shrimp. Adding a thin layer of mashed avocado or cream cheese helps everything hold together.
Roll tightly and slice. You still get the familiar sushi flavor combination, just without the carb-heavy base. Try these Smoked Salmon & Avocado Sushi Rolls or Quick Veggie Nori Wraps.
3. Cucumber-Wrapped Rolls
Thin slices of cucumber make a surprisingly sturdy wrap. Use a vegetable peeler or mandoline to create long strips, then layer and roll them around your fillings.
They add crunch and work especially well with salmon, shrimp, crab, or cream cheese-based fillings. These Salmon Mousse Cucumber Rolls are a good example of how well this method works.
4. Smoked Salmon Wraps
Smoked salmon can act as both wrap and filling. Lay out thin slices, spread with cream cheese or mashed avocado, add something crunchy like cucumber or green onion, and roll.
It’s satisfying on its own and doesn’t need much else. These Sushi Smoked Salmon Roll-Ups show how simple this can be.
5. Egg Wraps or Japanese-Style Omelets
Thin omelet sheets make a flexible and protein-rich base. You can keep them savory or make a Japanese-style tamago using a low-carb sweetener.
They hold fillings well and add more substance than vegetable-only wraps. These Curried Chicken Sushi Hand Rolls use both nori and egg wraps and work especially well for meal prep.
6. Cauliflower Rice Sushi
Cauliflower rice is often the first substitute people try. When prepared properly, it holds up well and absorbs seasoning similarly to rice.
The key is removing excess moisture. Lightly cook it, let it cool, and squeeze it dry using a clean kitchen towel or nut milk bag. Season with rice vinegar, salt, and a small amount of low-carb sweetener. If you want it slightly stickier for rolling, mixing in a little cream cheese or homemade sugar-free mayonnaise helps everything bind together.
It works especially well in recipes like Spicy Salmon Sushi Rolls, the California Sushi Burrito, or Spicy Prawn Hand Rolls, where the fillings bring plenty of flavor and texture.

7. Palmini (Hearts of Palm Rice)
Palmini rice is made from hearts of palm and has a slightly tangy flavor straight from the can. If that taste stands out too much, a quick boil followed by thorough draining and cooling helps mellow it.
It doesn’t mimic rice exactly, but it provides structure and works well when the fillings do the heavy lifting.
8. Shirataki Rice
Shirataki rice is extremely low in carbs and very light. The texture is slightly firmer and more elastic than traditional rice, so it’s not everyone’s favorite on its own.
Mixing it with a bit of cauliflower rice or a small amount of cream cheese improves the texture and makes it easier to roll. If your priority is keeping carbs as low as possible, this is one of the lowest-carb options available.
Choosing the Right Fillings for Low-Carb Sushi
Once you remove the rice, the fillings matter more. This is where you make it satisfying instead of feeling like something is missing. Stick with protein, healthy fats, and vegetables that add some crunch or contrast.
Fish & Seafood
Fatty fish works especially well because it keeps you full and doesn’t need much added to taste good. Salmon, tuna, mackerel, and yellowtail are all solid options. Shrimp and crab also work — just check the label if you’re using imitation crab, since it often contains starch.
If you like eel (unagi), remember the sauce is usually sweet. You can make a similar version at home using this Sugar-Free Teriyaki Sauce.
You can also try octopus, salmon roe (high in Lyso-DHA), or sea urchin if you want something different. They’re naturally low in carbs and work well in rice-free rolls.
Meats
Sushi doesn’t have to be seafood. Thinly sliced grilled beef, steak, smoked chicken, or pork belly all work in hand rolls or nori wraps. These options are especially helpful if you’re making sushi at home and want something more filling.
Vegetables
Avocado is an easy go-to. Cucumber adds crunch. Bell peppers, daikon radish, asparagus, and green onions all work well too. You don’t need a long list. Just a few simple ingredients layered together usually works better than overloading the roll.
Dairy & Eggs
Cream cheese helps keep the roll intact and is common in many Western-style rolls. Mild cheeses like mozzarella can also work if sliced thin. Eggs are another easy option. Thin omelet strips or tamago-style egg add structure and extra protein without adding carbs.
Extra Flavor
This is where you can adjust things to your taste. Mix mayonnaise with a little sriracha for heat. Add roasted sesame seeds. Use homemade Pickled Radishes or Sugar-Free Pickled Ginger. You don’t need much — just enough to balance the roll.
Does Resistant Starch Make Rice Keto-Friendly?
You may have heard that cooling rice increases its resistant starch content and lowers its impact on blood sugar. When rice is cooked and then cooled, some of its starch changes structure and becomes less digestible, and reheating doesn’t completely reverse that process.
However, this doesn’t turn rice into a low-carb food. Even with more resistant starch, the total carbohydrate content remains high. While it may slightly reduce the blood sugar response, it doesn’t make sushi rice suitable for a strict keto approach.
If you’re following a more flexible low-carb diet and keeping portions small, you could experiment and see how you respond. But if your goal is staying in ketosis, resistant starch doesn’t meaningfully change the carb load of rice.
FAQs
Can I eat sushi at a restaurant on keto?
Yes. The easiest option is sashimi. You can also ask for rolls without rice or look for cucumber-wrapped versions. Avoid sweet sauces and imitation crab unless you’ve checked the ingredients.
Is soy sauce low in carbs?
Traditional soy sauce is low in carbs and usually fine in small amounts. If you avoid gluten, choose tamari. If you avoid soy, coconut aminos work, but check the label since some brands contain added sugar.
How do I make cauliflower rice stick together like sushi rice?
The most important step is removing moisture. After cooking, let it cool and squeeze it dry using a towel. Mixing in a small amount of cream cheese or mayonnaise can also help it bind.
Is pickled ginger keto-friendly?
Traditional pickled ginger often contains sugar. Look for a sugar-free version or make your own at home to keep carbs low.
Can I use frozen fish for sashimi?
Yes, but it should be labeled sushi-grade or suitable for raw consumption. When in doubt, buy from a reputable fishmonger and follow proper food safety guidelines.
Final Thoughts
Once you stop thinking of sushi as “rice with toppings,” it gets a lot easier to make it work on a low-carb diet.
The fish, the seaweed, the fillings, the sauces — that’s where most of the substance comes from anyway. Rice is just the structure. And structure is replaceable.
Some days that might mean ordering sashimi. Other days it might mean cucumber rolls, cauliflower rice, or simply wrapping everything in nori and calling it done.
It doesn’t have to be complicated. You don’t need to perfectly recreate traditional sushi to enjoy it. You just need a base that fits the way you’re eating now.
