Bring a pot of well-salted water to a boil, then add your chosen pasta and allow to cook until al dente – about 12-14 minutes (check the package instructions).
Once cooked, drain the pasta, making sure to reserve about a cup of the pasta water. When added to the creamy shrimp pasta later, it'll help thicken the sauce.
Prepare the shrimp
As your pasta is cooking, add the shrimp to a large bowl. Pour the cajun seasoning and olive oil over and toss so the shrimp are completely coated. You can reduce the amount of seasoning you use depending on how much heat you want.
In a skillet or large frying pan, melt the butter. Stir in the minced garlic, cooking until fragrant.
Add the seasoned shrimp and sauté for a couple of minutes on each side until they've turned a vibrant pink color. Remove from the skillet and cover to keep warm.
Make the sauce
In the same skillet, add the cream and deglaze the pan (scraping any saucy bits stuck to the bottom). Once the cream has heated, add the parmesan and tomatoes and bring the sauce to a simmer.
Add a little of the pasta water to help thicken the sauce. Adjust how much you use depending on how the sauce is.
Combine and serve
Add the cooked pasta to the cajun sauce, then add the cooked shrimp. Mix well until the pasta and shrimp are completely combined and covered in creamy sauce.
Garnish with fresh chopped parsley and enjoy!
