Keto Prawn Stir Fry

This simple keto prawn stir fry is incredibly delicious, healthy and easy to make. In fact it’s so tasty and satisfying that you won’t even realise that you are eating a low-carb meal! The recipe uses spiralised courgette instead of noodles – but if you aren’t watching your carbs you could easily use normal noodles instead.

While on lockdown I am conscious that I’m not moving so much and while I’ve started doing stair walking (I live on the 28th floor of a tall apartment building) I need to adjust my diet to match this lifestyle, albeit temporary. I’m not cutting carbs completely, but I am trying to reduce them. I’ll likely have a few more to share with you over the coming weeks!

This stir fry uses a really simple but completely delicious dressing of soy sauce and lime juice. It might not sound like much but when it combines with the chilli and coriander in the pan it’s tasty and fresh.

Can you reheat prawn stir fry?

I wouldn’t recommend reheating prawn stir fry if you can avoid it. Firstly prawns overcook very easily and the act of reheating them will most certainly make them tougher. Secondly the courgette noodles will be a lot soggier. The dish takes literally about 7-8 minutes to cook so if you want to eat a couple of nights in a row then prep everything and cook it from scratch both times.

If you do have leftovers though and you do want to reheat then it certainly won’t do any harm – and it will still taste great – there will just be some loss of texture. The best way to reheat is on the hob over a medium high heat until warmed through. You could use the microwave – but it will smell quite strong – you have been warned!

  1. You can use either raw or cooked prawns for this. Directions for both ways are in the steps. I usually prefer raw, but due to COVID related food supply issues I could only find cooked (and it was still totally yum)
  2. If you like a lot of spice then increase the amount of chilli to taste
