Creamy Cajun Shrimp Pasta brings restaurant magic right to your kitchen with bold flavors and a rich sauce that pleases everyone at the table. The Cajun-spiced shrimp deliver a gentle heat and pair perfectly with tender pasta in a silky cream sauce. When I am craving comfort food with a bit of excitement, this is my weeknight fix that never disappoints.
The first time I threw this together it instantly became my husband’s favorite pasta. He always asks for extra Parmesan on top which makes the dish feel even more special.
Ingredients
- Large shrimp: fresh or frozen the bigger size helps them stay juicy and not overcooked
- Rotini pasta: or any short noodle that catches the creamy sauce well
- Cajun seasoning: find a quality blend with layers of flavor not just heat I sometimes mix my own for control
- Heavy cream: gives lush richness use a good dairy brand for best taste
- Butter: provides richness and browns beautifully with the shrimp
- Olive oil: helps sear the shrimp evenly and lifts flavors from the pan
- Minced garlic: bring out real garlic over jarred for the sharpest flavor
- Grated Parmesan cheese: adds salty nutty depth freshly grated is best for easy melting
- Salt and pepper: to taste quality sea salt enhances the other seasonings
Step-by-Step Instructions
- Prepare the Shrimp:
- Pat dry the shrimp on paper towels then season generously with Cajun seasoning salt and pepper. Dry shrimp sear better and take on more flavor.
- Sear the Shrimp:
- Heat butter and olive oil in a wide skillet over medium high. Place shrimp in a single layer letting them cook undisturbed for one or two minutes each side. You want a golden crust and opaque center. Transfer to a plate to keep them tender.
- Cook the Garlic:
- If the skillet looks dry add a dab more butter. Drop in the minced garlic and gently stir for about thirty seconds. Once fragrant do not let it brown or it gets bitter.
- Make the Sauce:
- Lower the heat and slowly pour in the heavy cream. Use a wooden spoon to scrape up any bits stuck to the pan these give body and flavor. Simmer gently for three or four minutes until the sauce starts to thicken.
- Add Cheese:
- Sprinkle in the Parmesan while stirring so it melts smoothly into the sauce. Keep stirring until the sauce is creamy and coats the back of a spoon.
- Boil the Pasta:
- In a separate pot bring water to boil with a handful of salt. Cook your pasta until just al dente and drain but do not rinse. Reserving a splash of the pasta water helps adjust your sauce if needed.
- Combine:
- Tip the cooked pasta into the sauce stirring to coat well. Gently fold in the seared shrimp taking care not to overmix as you want the shrimp plump and coated not broken up.
- Serve:
- Plate immediately with extra Parmesan and maybe fresh parsley for a pop of green. This dish tastes best hot right from the stove.

Shrimp has always been my brother’s favorite so when I make this for family gatherings everyone dives in before I can even set down the serving spoon. I never have leftovers.
Storage Tips
Leftovers stay good for up to three days in a tightly sealed container in the fridge. For the best texture reheat gently over low heat adding a splash of cream or milk if needed. Do not microwave too long or the shrimp can toughen.
Ingredient Substitutions
You can use penne or fusilli if rotini is not handy. Chicken works well instead of shrimp just increase the cook time a bit. Light cream will work but the sauce will be less rich yet still tasty. If you do not eat Parmesan try Pecorino Romano for a sharper bite.
Serving Suggestions
This pasta shines with a simple green salad and crusty bread to wipe up extra sauce. I sometimes add roasted broccoli or lemony asparagus on the side for balance. On special nights a glass of chilled white wine pairs beautifully.
