Step 1

In a large pot, cook pasta according to the package directions. (Psst: We prefer our pasta al dente.) Meanwhile, in a large skillet, melt 2 tablespoons of butter over medium heat. Add the shrimp and 2 teaspoons of Cajun seasoning. Cook and stir until the shrimp turn pink, about three to five minutes. Remove the shrimp from the pan and keep them warm. Editor's Tip: Shrimp recipes are easy to overcook, so keep a close eye on them. An easy way to tell if your shrimp are fully cooked is to see whether they are curled into a nice, soft C shape. Overcooked shrimp will curl tightly into an O shape.

Step 2

In the same skillet, melt the remaining 2 tablespoons of butter over medium heat. Add the garlic. Cook and stir it until it's fragrant, about one minute. Then, whisk in the cream and bring it to a boil. Reduce the heat and simmer the cream, uncovered, until it has slightly thickened, four to six minutes.

Step 3

Stir in the Parmesan cheese, tomato and remaining 2 teaspoons of Cajun seasoning. Stir in the shrimp. Drain the pasta, then add it to the skillet and toss to coat it with the sauce. Garnish the pasta with fresh chopped parsley, if desired, and serve. Editor's Tip: If you want your Cajun shrimp pasta to be extra spicy, you can add additional Cajun seasoning or a few teaspoons of Calabrian chilies or crushed red pepper flakes. A dash of hot sauce is another way to turn up the heat.
