1-Cook 8 oz penne pasta in salted water until al dente based on package instructions. Reserve some pasta water, then drain and cover the pasta to keep it warm.

2-Coat 1 lb large shrimp with 1 tablespoon Cajun seasoning. Heat 1 tablespoon oil in a deep skillet over medium heat and sauté the shrimp for 1-2 minutes per side until opaque, then remove and cover to keep warm.

3-In the same skillet, melt 2 tablespoons unsalted butter with 2 minced garlic cloves and cook for 30 seconds until fragrant. Add 1/2 cup diced tomatoes and sauté for 2-3 minutes.

4-Pour in 1 1/2 cups heavy whipping cream, the remaining 1 tablespoon Cajun seasoning, and 1/2 cup grated parmesan cheese. Bring to a simmer, reduce heat to medium-low, and cook for 2-3 minutes until the sauce thickens.

5-Return the shrimp and pasta to the skillet; stir to coat everything with the sauce. If the sauce is too thick, add some reserved pasta water to thin it out.

6-Serve right away, topped with extra parmesan cheese and 2 tablespoons chopped parsley if you like. This step can be similar to easy pasta recipes on our site for more ideas.
