The majority of the pasta recipes on this website is strictly Italian in origin or inspiration. However, the recipe I am sharing today is inspired by the flavours of the American South. New Orleans to be exact actually.
It’s difficult not to be seduced by the rich, bold flavours of the Cajun cooking. I love everything about it. The spice, the colour, the seasonality of the ingredients used, and especially the rustic nature.
The recipe for the Cajun shrimp pasta is a quick one to make but it delivers deep and vibrant taste, which usually comes from long hours of cooking.
The distinct Cajun flavour comes from the seasoning, which is very easy to mix together. You can also buy it already mixed. I prefer making my own, so I can control the salt content in my food.
Cajun Spice
Every cook has a slightly different mix when it comes to the Cajun seasoning but the most common and used ingredients remain the same.
- Paprika (I prefer smoked paprika)
- Cayenne
- Oregano
- Thyme
- Garlic Powder
- Black Pepper
- Salt
Some people also add onion powder. As I mentioned I prefer mixing my own, so the spices stay fresher, more potent and therefore, more flavourful.
Cajun Pasta Ingredients
Onions, green peppers and celery are considered the holy trinity of the Cajun cuisine and I wanted to use them in my recipe. In the end, I did leave the celery out as I found the crunchy texture clashed with the creamy sauce a bit too much.
Shrimp is another important ingredient and this pasta recipe featured it prominently. Shrimp is well coated with my homemade Cajun seasoning, then browned to create that slightly blackened exterior the Cajun cooking is known for.
Feel free to add sausage, especially Andouille sausage or even chicken!
The sauce is a combination of crushed tomatoes, heavy cream and Parmesan cheese. The mix of the sweet and tangy tomatoes, the rich cream and deeply savoury Parmesan cheese blend well, while holding its own, when paired with the spicy seasoning.
Recipe Tips and Notes
- If using previously frozen and defrosted shrimp, pat it dry before coating with the Cajun seasoning.
- Cook shrimp quickly as overcooking it will result in dry, rubbery flesh.
- Sear sliced green peppers over high heat. We want to see some colour on them for more authentic flavour.
- I used a combination of crushed tomatoes and heavy cream to make the sauce. You can skip the cream altogether and make this pasta dairy free. Replace the cream with crushed tomatoes or tomato passata and leave out Parmesan cheese if you choose to make a no cream pasta.
- Tagliatelle, fettuccine or linguine are my favourite pasta choices for a creamy sauce.
- Don’t forget to reserve ½ cup of pasta water to add to the sauce later.
- Top with sliced green onions and more Parmesan cheese before serving.
