How to Make Creamy Cajun Shrimp Pasta
-
Cook the Pasta: Boil the penne pasta in a large pot of salted water until al dente, following the package instructions. Keep a cup of pasta water aside; then drain the pasta and cover it to stay warm.
-
Sauté the Shrimp: Season the shrimp with 1 tablespoon of cajun seasoning. In a deep skillet, heat 1 tablespoon of olive oil over medium heat. Add the shrimp in a single layer and sauté for about 1-2 minutes per side until they turn pink and opaque. Remove them from the skillet and cover to keep warm.
-
Melt the Butter: In the same skillet, melt 2 tablespoons of unsalted butter and add the minced garlic. Cook for 30 seconds until fragrant, stirring gently to avoid burning.
-
Add Tomatoes: Toss in the diced tomatoes and sauté for about 2-3 minutes, letting them soften and release their juices into the pan.
-
Create the Sauce: Pour in the heavy whipping cream, add the remaining 1 tablespoon of cajun seasoning, and stir in the grated parmesan cheese. Bring the mixture to a gentle simmer, then reduce the heat to medium/low and cook for another 2-3 minutes until the sauce thickens slightly.
-
Combine Everything: Return the shrimp and cooked pasta back into the skillet, stirring well until the noodles are evenly coated with the creamy sauce. If the sauce is too thick, add a splash of the reserved pasta water to reach your desired consistency.
-
Serve and Enjoy: Spoon the creamy cajun shrimp pasta into bowls, and garnish with extra parmesan and chopped parsley if you like.
Optional: A squeeze of fresh lemon juice adds a delightful brightness to the dish.
