Step-by-Step Instructions: How to Make Cajun Prawn Pasta
1. Prepare the Spice Mix
In a small bowl, mix all the spices together and set aside.
2. Cook the Pasta
Bring a pot of salted water to a boil and cook your pasta one minute less than the packet instructions. Before draining, scoop out ½ cup of pasta water and set it aside. Rinse the pasta under cold water to stop it from cooking further.
3. Season & Sear the Prawns
Toss the prawns with half of the Cajun spice mix and a drizzle of olive oil. Sear them in a hot pan for 1-2 minutes per side until they change color, then remove and set aside.
4. Build the Creamy Cajun Sauce
In the same pan, deglaze with a little water, scraping up the browned bits for extra flavor. Add the red onion and garlic, sautéing until soft. Stir in the capsicum and tomato paste, cooking for a minute to develop the flavors.
Now, add the remaining Cajun spice mix and pour in the thickened cream, letting it simmer for 3-4 minutes until slightly thickened.
5. Combine Everything
Return the prawns to the pan, toss in the baby spinach, and let it wilt. Stir in the parmesan and a squeeze of fresh lemon juice.
Now, add the cooked pasta and toss everything together. If the sauce feels too thick, gradually add a splash of reserved pasta water to create a silky consistency.
6. Serve & Enjoy
Plate up your Spicy prawn pasta, sprinkle over extra parmesan, and dig in while it’s hot!

Frequently Asked Questions
Can I use frozen prawns?
Yes! Just thaw them completely before cooking and pat them dry to prevent excess moisture.
What’s the best pasta for this recipe?
I love penne or rigatoni because it holds onto the creamy sauce so well, but linguine, or fettuccine all work too!
How can I store leftovers?
Keep leftovers in an airtight container in the fridge for up to 2 days. Reheat gently with a splash of cream or pasta water to revive the sauce.
