Ingredients You’ll Need
Simple yet essential, each ingredient in this recipe plays a crucial role in creating the perfect balance of flavor, texture, and color. From the succulent shrimp to the creamy elements, every component elevates this dish into a luxurious and satisfying meal.
- 8 oz penne pasta: Choose penne for its ability to hold sauce in its tubes, ensuring every bite is flavorful.
- 1 lb large shrimp, peeled and deveined: Fresh or thawed shrimp create the star protein packed with natural sweetness to complement the Cajun spices.
- 1 tablespoon olive oil: Helps sear the shrimp perfectly without sticking.
- 2 tablespoons Cajun seasoning, divided: This blend infuses the dish with the characteristic smoky, spicy Cajun flair; adjust to your heat preference.
- 2 tablespoons unsalted butter: Adds richness and smoothness to the sauce while sautéing garlic.
- 2 garlic cloves, minced: Provides a fragrant, aromatic base for the sauce.
- ½ cup diced tomatoes: Adds a touch of acidity and color to balance the creaminess.
- 1 ½ cups heavy whipping cream: The heart of the sauce, lending that luscious, creamy texture.
- ½ cup grated parmesan cheese, plus more to serve: Gives a salty, nutty depth and helps thicken the sauce beautifully.
- 2 tablespoons parsley, chopped (optional, for garnish): Offers a fresh pop of green and a mild herbaceous note to finish the dish.
How to Make Creamy Cajun Shrimp Pasta Recipe
Step 1: Cook the Pasta
Start by bringing a large pot of salted water to a boil and cook the penne pasta until it’s perfectly al dente, following package instructions. Be sure to save a little pasta water before draining – that starchy water is your secret weapon to tweak the sauce to just the right consistency later. Once drained, cover the pasta to keep it warm while you move on to the next steps.
Step 2: Cook the Shrimp
Toss the peeled and deveined shrimp with 1 tablespoon of Cajun seasoning, making sure each piece is evenly coated. Heat olive oil in a deep skillet over medium heat, then add the shrimp in a single layer. Sauté each side for 1 to 2 minutes until they turn opaque and are cooked through. Don’t worry about overcooking here; the shrimp will get a chance to absorb more flavor later. Remove the shrimp from the skillet and keep them warm, covered.
Step 3: Sauté Aromatics
Using the same skillet (no need to wash it), melt the butter and add the minced garlic. Cook just for about 30 seconds until it’s fragrant but not browned, releasing those incredible garlicky notes. Then add the diced tomatoes and sauté for 2-3 minutes, letting their freshness meld with the butter and garlic to build a flavorful foundation for your sauce.
Step 4: Make the Creamy Cajun Sauce
Pour in the heavy whipping cream followed by the remaining tablespoon of Cajun seasoning and the grated parmesan cheese. Stir everything gently and bring the mixture to a simmer. Lower the heat to medium-low and let it thicken for 2 to 3 minutes. This step is where the sauce becomes silky and rich, with the parmesan melting perfectly while the seasoning infuses deep layers of flavor.
Step 5: Combine and Serve
Return the shrimp and pasta back into the skillet, mixing gently so every penne is luxuriously coated in that creamy Cajun sauce. If the sauce feels too thick, splash in some of the reserved pasta water a little at a time to loosen it up without losing any flavor. Serve immediately, garnished generously with extra parmesan and bright sprigs of chopped parsley if you have it on hand. This dish shines best fresh and steaming!
How to Serve Creamy Cajun Shrimp Pasta Recipe

Garnishes
A fresh sprinkle of chopped parsley adds color and a mild herbaceous brightness that cuts through the creaminess beautifully. Don’t skimp on an extra grating of parmesan cheese on top for that cheesy, savory finish that will have everyone digging back for seconds.
Side Dishes
Pair this dish with a crisp green salad dressed lightly with lemon vinaigrette to add a refreshing contrast. Garlic bread or crusty French bread is also a perfect side to mop up every last bit of the luscious sauce, making your meal feel wonderfully complete and satisfying.
Creative Ways to Present
For a fun twist, serve this Creamy Cajun Shrimp Pasta Recipe in individual shallow bowls with a sprinkle of extra Cajun seasoning on top for a little visual kick. You can also add a wedge of lemon on the side for anyone who loves a bright citrus burst at the end.
Make Ahead and Storage
Storing Leftovers
After enjoying your meal, store any leftovers in an airtight container in the refrigerator. The pasta and shrimp will keep well for up to 2 days, but since seafood is delicate, try to consume it quickly for best taste and safety.
Freezing
Freezing this dish isn’t highly recommended because the cream sauce might separate and change texture after thawing. However, if you must freeze, place it in a freezer-safe container and consume within 1 month, reheating gently to minimize sauce breakdown.
Reheating
Reheat leftovers gently on the stovetop over low heat, adding a splash of milk or cream to bring the sauce back to life and keep that signature creaminess. Avoid microwaving at full power to prevent the shrimp from becoming rubbery and the sauce from curdling.
FAQs
Can I use a different type of pasta for this recipe?
Absolutely! While penne is great for holding onto the sauce, you can substitute with rigatoni, fusilli, or even fettuccine depending on your preference. Just make sure to cook your pasta al dente for the best texture.
How spicy is this Creamy Cajun Shrimp Pasta Recipe?
The level of spice depends on your Cajun seasoning blend. If you prefer mild heat, start with less seasoning and increase gradually. For those who love some punch, feel free to add extra or include a pinch of cayenne pepper for more kick.
Can I use frozen shrimp in this recipe?
Yes, frozen shrimp works well as long as it’s fully thawed and patted dry before cooking. This helps achieve that perfect sear and keeps the shrimp juicy inside.
Is there a dairy-free version of this pasta?
You can make a dairy-free version by swapping out the heavy cream for coconut cream and using a dairy-free cheese alternative. Keep in mind this will slightly alter the classic flavor but still deliver a creamy, delicious dish.
Can I prepare any parts of this recipe ahead of time?
You can cook the pasta and shrimp ahead and store them separately in the fridge. When ready to eat, quickly prepare the sauce and combine everything on the stovetop. This makes for a fast and easy weeknight meal.
