Ingredients You’ll Need
This recipe uses straightforward ingredients that pack tons of flavor. Each component plays a key role in making this creamy Cajun shrimp pasta a winner.
The Shrimp: Fresh vs. Frozen
For the best texture, large shrimp around 21/25 count is ideal since they hold up well during cooking and give you that satisfying bite. If using frozen shrimp, thaw them properly by placing in the fridge overnight or running under cold water while still in their sealed bag. Always peel and devein to ensure tenderness and to let the Cajun seasoning really shine.
The Cajun Seasoning: Your Key to Flavor
Store-bought Cajun seasonings vary widely in salt and spice levels, so adjust accordingly. If you’re a flavor control freak like me, I have a homemade Cajun seasoning recipe you can try that balances heat, smokiness, and seasoning perfectly for this dish. This ensures you get just the right kick without overpowering the shrimp or creamy sauce.
The Cream Sauce Components
Heavy whipping cream adds rich, velvety smoothness, making the sauce luscious and decadent. Freshly grated Parmesan melts beautifully, giving depth and a savory balance to the creaminess. Garlic brings aromatic warmth, while diced tomatoes add a subtle tang and texture contrast. Using fresh Parmesan over pre-shredded yields a smoother, less grainy sauce.
Step-by-Step: How to Make Creamy Cajun Shrimp Pasta
Making this dish is simple and satisfying. First, cook your penne pasta until al dente, setting aside some pasta water for the sauce. Then, sauté the Cajun-seasoned shrimp until just opaque. Next, create the sauce with butter, garlic, tomatoes, cream, Cajun seasoning, and Parmesan until thickened. Finally, toss the shrimp and pasta in the sauce until everything is perfectly coated and warm. Follow the sensory cues like shrimp curling into a C-shape and sauce coating the back of a spoon for guaranteed success. Step-by-step photos can guide you through each stage.
Aisha’s Expert Tips for a Foolproof Pasta
- Salt your pasta water liberally to enhance the pasta’s flavor from the inside out.
- Don’t overcrowd the pan when cooking shrimp to get a nice sear and prevent steaming.
- Use freshly grated Parmesan for a creamier, smoother sauce with better flavor.
- Reserve pasta water to thin the sauce perfectly—don’t be afraid to add a splash as needed.
Variations and Substitutions
| Variation/Substitution | How to Do It | Notes |
|---|---|---|
| Add Andouille Sausage | Slice and sauté Andouille Sausage along with shrimp | Adds smoky, hearty flavor to the dish |
| Add Vegetables (peppers, onions, spinach) | Sauté veggies after shrimp, before making the sauce | Boosts nutrition and adds color and texture |
| Make it Lighter (Health-Conscious) | Use half-and-half instead of heavy cream | Reduces fat, slightly less rich but still tasty |
| Make it Gluten-Free/Dairy-Free | Substitute gluten-free pasta and use dairy-free cream | Adjust seasoning, texture will be slightly different |
What to Serve with Cajun Shrimp Pasta
Pair this creamy Cajun shrimp pasta with a simple green salad for freshness and balance. Garlic bread is another perfect companion that soaks up the delicious sauce. Both sides keep the meal comforting and satisfying without overshadowing the main dish.
Storage and Reheating Guide
To store leftovers, place the pasta in an airtight container and refrigerate for up to 3 days. When reheating, warm it gently on the stovetop over low heat. Add a splash of milk or cream to loosen the sauce and prevent it from breaking or turning oily. Stir frequently until heated through for best results.
Ingredients
- 8 oz penne pasta
- 1 lb large shrimp (peeled and deveined)
- 1 Tbsp olive oil
- 2 Tbsp cajun seasoning (divided or added to taste depending on brand used)
- 2 Tbsp unsalted butter
- 2 garlic cloves (minced)
- 1/2 cup diced tomatoes
- 1 1/2 cups heavy whipping cream
- 1/2 cup grated parmesan cheese (plus more to serve)
- 2 Tbsp parsley to garnish (optional)
Instructions
- Cook the penne pasta in a pot of salted water until al dente according to package instructions. Keep some of the pasta water for the sauce then drain the pasta and cover to keep warm.
- Coat the shrimp with 1 Tbsp of the cajun seasoning. In a deep skillet, heat 1 Tbsp oil over medium heat. Once hot, add the seasoned shrimp in a single layer and sauté for about 1-2 minutes per side, or until the shrimp is no longer translucent, remove from skillet and cover to keep warm.
- In the same skillet, melt 2 Tbsp butter with the minced garlic and cook 30 seconds until fragrant. Add in the diced tomatoes and sauté for about 2-3 minutes.
- Pour in the heavy whipping cream, remaining 1 Tbsp cajun seasoning and grated parmesan cheese. Bring to a simmer then reduce to medium/low heat and continue 2-3 minutes or until the sauce thickens.
- Add the shrimp and pasta back into the skillet and stir until the noodles are coated in sauce and everything is heated through. If needed, add a splash of the reserved pasta water to thin the sauce. To serve, garnish with more parmesan and chopped parsley, if desired.

Notes
Frequently Asked Questions (FAQ)
How do I keep my shrimp from getting rubbery?
Cook shrimp quickly over medium heat and avoid overcooking. Shrimp is done when it curls into a C-shape and turns opaque.
Why is my cream sauce runny or broken, and how can I fix it?
A runny sauce may need more simmering to thicken. If broken, whisk in a little cold cream or milk off heat to help bring it back together.
Can I use a different type of pasta?
Yes, any short pasta like fusilli or rigattoni works well. Avoid delicate pastas that won’t hold the rich sauce.
Can I make this Creamy Cajun Shrimp Pasta ahead of time?
You can make it up to a day ahead; reheat gently with added cream or milk to maintain sauce consistency.
