Juicy king prawns in a spicy and just-a-little-bit-creamy sauce with lots of noodles, this cajun prawn noodle stir-fry makes a lovely, lip-smacking dinner. Ready-cooked noodles help to speed up this recipe and means we only need to use one pan!

Nicky’s recipe notes
Cajun spice is one of those shortcuts that adds loads of flavour.
The basic ingredients usually include black & white pepper, salt, Cayenne, paprika, onion & garlic powder. Some contain oregano, thyme, fennel, cumin and sugar too.
I see it as an ‘everything spice mix’ – if you want to add flavour and you like a bit of heat, it’s an easy option, without having to open all your other spice jars!
I use it to coat king prawns for this recipe, before frying them up with noodles and veggies.
You might also find it surprising that I add a little creme fraiche to the dish. Sounds unusual, but the slight creaminess balances the tangy spiciness perfectly. You can swap out with a little double (heavy) cream if you haven’t got creme fraiche in.

📋 Ingredients

Noodles – I use ready-cooked egg noodles to speed up the process for this recipe, but you can use dried noodles, just cook as per the packet instructions.
Prawns – I use raw king prawns, make sure you peel and devein before cooking. I usually buy them frozen, as they’re cheaper. Then defrost in a sieve over a bowl before using.
Oil – Use a neutral oil such as vegetable, sunflower, or avocado.
Chicken Stock – You can use a crumbled stock cube dissolved in hot water, or use Homemade Chicken Stock.

***Full recipe with detailed steps in the recipe card at the end of this post***
- First, coat the king prawns in the Cajun seasoning, then fry until pink and remove from the pan.
- Fry up the pepper and onions in oil, along with garlic, chilli, salt and pepper, then add the stock, Worcestershire sauce, and crème fraiche.
- Those ready-cooked noodles go in next and are stir fried until hot, before adding the prawns back in. It’s all finished off with the addition of some freshly chopped coriander and a sprinkling of chilli flakes.
Pro Tip
Swap out the crème fraîche for 3 tablespoons of full-fat coconut milk or double (heavy cream) if you prefer.
If you’re a fan of seafood and you like a bit of spice, this dinner is perfect!
