In a large pot, heat 2 tablespoons of olive oil over medium-high heat. Once the oil is shimmering, add the shrimp and cook for about 2-3 minutes, stirring occasionally, until they turn pink and opaque. Remove the shrimp from the pot and set aside, ensuring they don’t overcook.

In the same pot, add a splash more olive oil if needed and toss in 3 minced garlic cloves, 1 chopped onion, and 1 diced bell pepper. Sauté these aromatic vegetables over medium heat for about 3-5 minutes until they soften and become fragrant, stirring frequently to avoid sticking.

Sprinkle in 2 tablespoons of Cajun seasoning, stirring well to coat the vegetables evenly. Pour in 1 cup of heavy cream, followed by ½ cup of grated Parmesan cheese. Stir continuously for about 5 minutes, allowing the sauce to simmer and thicken to a creamy consistency that clings to the back of a spoon.

Next, bring the cooked pasta to the pot, along with the sautéed shrimp. Toss everything gently until the pasta is generously coated in the creamy Cajun sauce. Continue heating over low for an additional minute, allowing flavors to meld beautifully.

Finally, plate your Creamy Cajun Shrimp Pasta, garnishing with fresh parsley and additional Parmesan cheese, if desired. Serve immediately for a delightful, hearty meal that showcases the creamy goodness and bold flavors of this dish.
