These keto sushi rolls taste just as good as the real thing! This easy low carb cauliflower sushi recipe gives you all the flavours we love about this Japanese treat, only without all the carbs.
I’ve been missing sushi so much!
When we go to a Japanese restaurant, there is just not a lot of choice since I’ve gone on a low carb diet. Nearly all dishes contain either masses of rice, or come with sauces that are high in sugar (like teriyaki sauce).
I tend to stick to miso soup, edamame beans and sashimi. However, this is never a truly satisfying meal. Sashimi, as most of you will know, is pieces of raw fish. It’s delicious, but not something you’ll want to fill your stomach with. Plus, it’s really expensive.
The problem with regular sushi is – you guessed it – the rice.
Can you eat sushi on keto?
The base ingredient in regular sushi is a vinegar-flavoured sticky rice. Rice is starchy and will affect your blood sugar levels. 100 grams of cooked sushi rice contains 28.7 grams of carbs (source: Livestrong). Therefore, it is not suitable for the keto diet.
Cauliflower rice sushi
It was time to make low carb sushi rolls without rice!
Now, of course it would be possible to make no rice sushi – that is, to simply leave out the rice altogether and just fill the nori sheets with fish and vegetables.
But I am a big fan of cauliflower rice (check out my Keto Cauliflower Egg Fried Rice!). And I think the cauliflower rice mix I’m using mimics the texture of sushi rice really well.
The ‘rice’ is gently sautéed to al-dente. This takes away the slightly pungent cauliflower flavour you get with eating it raw.
It is then mixed with mayo or cream cheese to provide the stickiness you get with normal sushi.
Lastly, I’ve added apple cider vinegar (or use white vine vinegar) instead of mirin and roasted sesame seeds for sushi authenticity and a bit of wow.
How to make keto sushi rolls – step by step:
Here are the ingredients we’re using:
For the rice: cauliflower, oil and vinegar, cream cheese and white sesame seeds
For the filling: smoked salmon or sushi grade raw salmon, cucumber, red bell pepper and avocado
To roll: 2 nori sheets
To serve: pickled ginger and/or coconut aminos
1.) Place the cauliflower florets in a food processor and pulse using the S blade until they resemble rice.
2.) Heat 1 tbsp of oil in a non stick frying pan or cast iron skillet. Fry the cauliflower on a low/ medium heat for 5 – 6 minutes until al-dente. Remove from the pan and allow to fully cool.
3.) Dry fry the sesame seeds in a non stick pan for 4 – 5 minutes on a low – medium heat until golden. Allow to cool.
4.) Once the rice has fully cooled, place in a bowl and mix with the cream cheese or mayonnaise, vinegar and sesame seeds.
5.) Meanwhile, prepare the veggies. Slice the cucumber and pepper into thin strips, discarding the seeds. Slice the avocado.
6.) Place the nori on a bamboo mat or clingfilm. Add the rice, leaving about 1 cm at the two opposing seal edges. Layer the cucumber, pepper, avocado and smoked salmon and once edge and tightly roll using the mat. Brush the sealing edge with a little water and press to seal. Slice into keto sushi rounds with a sharp knife and repeat for the second roll.
Low carb sushi rolls fillings
As always, there are lots of options depending on your personal preference.
I used smoked salmon for convenience. But you can of course use raw sushi grade salmon or tuna if you prefer. It’s important to use sushi grade fish and NOT raw wild salmon. Sushi grade (i.e. farmed) is required for safety. Which makes me wonder – have you tried my Superb Salmon Ceviche???
Other fish and seafood fillings we have tried are cooked smoked mackerel, cooked prawn and crab.
There’s no added salt in this keto sushi recipe because of the salt in the smoked salmon. But if you are using raw salmon, you can add a pinch of salt to the cauliflower rice.
I chose the Japanese sushi staples avocado and cucumber plus peppers, because I wanted a pop of colour. Other possible vegetable fillings for cauliflower sushi would be cabbage, bean sprouts, courgettes, a little carrot, kale, spinach, watercress, rocket, or even roasted low carb veggies – all finely sliced.
Keto Sushi Top Tips
Ensure the cauliflower rice is fully cooled before mixing with the cream cheese or mayonnaise mix to prevent the nori sheets from shrivelling up.
Ideally, use a bamboo mat to roll. If you don’t have one, use cling film. It will help you make a nice neat and tight keto sushi roll.
Use a very sharp knife to cut and clean your knife between cuts.
For a green sushi why not try replacing the cauliflower with broccoli rice. Just follow the same method but use broccoli florets instead of cauliflower.
Can you store cauliflower sushi?
This recipe is best enjoyed fresh. I don’t recommend to store keto sushi for longer than a day in the fridge. The cauliflower will start to release liquid after that and the sushi will become soggy.
If you want to save time on the day, consider preparing the cauliflower rice a day ahead. Store it in the fridge in an airtight container. This way, you don’t have to wait for it to cool down and you can assemble everything in one go.
