Step‑by‑Step Instructions for Cajun Shrimp Pasta
Step 1: Thaw the Shrimp
If you’re using frozen shrimp, place them under cold running water for about 10-15 minutes until they’re fully thawed. Alternatively, you can let them sit in the refrigerator overnight. Ensure the shrimp are peeled and deveined for the best texture in your Cajun Shrimp Pasta.
Step 2: Cook the Pasta
Bring a large pot of salted water to a rolling boil over high heat. Add in the penne pasta and cook according to the package instructions, typically around 10-12 minutes, until al dente. Remember to reserve 1 cup of the pasta water before draining, as it will help adjust the sauce later!
Step 3: Season and Sauté the Shrimp
While the pasta cooks, season the thawed shrimp with half of the Cajun seasoning, tossing to evenly coat. In a deep skillet, heat 2 tablespoons of olive oil over medium heat. Once shimmering, add the shrimp and cook for 1-2 minutes per side until pink and opaque. Remove the shrimp from the skillet and keep warm.
Step 4: Prepare the Sauce Base
In the same skillet, melt 2 tablespoons of unsalted butter over medium heat. Add 3-4 cloves of minced garlic and the remaining Cajun seasoning. Sauté for about 1 minute or until the garlic is fragrant and golden, being careful not to burn it, as this will enhance the flavors of your Cajun Shrimp Pasta.
Step 5: Add Tomatoes and Simmer
To the garlic and butter mixture, stir in one can of diced tomatoes, cooking for an additional 1-2 minutes. Allow the mixture to bubble lightly and the flavors to meld, while reducing the heat to medium-low. This step adds acidity and depth to the sauce, making it rich and flavorful.
Step 6: Create the Creamy Sauce
Gradually pour in 1 cup of heavy whipping cream while stirring continuously to combine. Add 1 cup of grated Parmesan cheese, mixing until melted and the sauce thickens, about 3-4 minutes. If it’s too thick, stir in some reserved pasta water to reach your desired creamy consistency for the Cajun Shrimp Pasta.
Step 7: Combine Shrimp and Pasta
Return the cooked shrimp to the skillet along with the drained penne pasta. Toss everything together until well coated in the sauce, allowing it to heat through for a minute or so. This ensures your Cajun Shrimp Pasta is infused with all those lovely flavors.
Step 8: Garnish and Serve
Before serving, sprinkle additional grated Parmesan cheese and chopped parsley over the pasta for a fresh, vibrant finish. This not only enhances the taste but also makes your Cajun Shrimp Pasta visually appealing. Plate up and enjoy your cozy, creamy dish!
