How to Make Cajun Shrimp Pasta
Don’t worry – this recipe is way easier than it sounds, and you’ll feel like a chef when you’re done making it!
Step 1: Season Those Shrimp
Mix your 1 pound large shrimp with 2 tablespoons Cajun seasoning and 1 tablespoon olive oil in a bowl. Get your hands dirty and toss everything around until each shrimp is covered in that spicy goodness.
Step 2: Boil the Pasta
Fill a big pot with water, add 1 tablespoon salt, and bring it to a crazy bubble. Toss in 8 ounces penne pasta and cook for about 8-10 minutes. Save ½ cup of that pasta water before you drain it – you’ll thank me later!
Step 3: Cook the Shrimp
Heat up your large skillet nice and hot. Drop in 1 tablespoon butter and watch it sizzle. Add your seasoned shrimp in one layer and cook for 2-3 minutes on each side until they’re pink and gorgeous.
Step 4: Make That Creamy Magic
Take the shrimp out and set them aside. Pour 1 cup heavy cream into the same pan and scrape up all those yummy brown bits. Let it bubble gently, then stir in ½ cup grated Parmesan until it’s smooth as silk.
Step 5: Bring It All Together
Put your pasta and shrimp back in the pan with the cream sauce. Toss everything around until it’s all coated and beautiful. Add some pasta water if it looks too thick.
Step 6: The Final Touch
Taste it and add more salt if you want. Sprinkle some fresh parsley and extra cheese on top. ENJOY every single bite – you earned it!

Tips for the Best Cajun Shrimp Pasta
These little tricks will take your pasta from good to absolutely amazing – I learned these the hard way!
- Dry Your Shrimp: Pat them with paper towels so they get crispy, not steamy.
- Don’t Cook Too Long: Shrimp get rubbery fast, so watch them like a hawk.
- Save That Water: Pasta water is like magic glue for your sauce.
- Fresh Cheese Rules: Grate your own Parmesan – the pre-made stuff just isn’t the same.
- Hot Pan: Get it sizzling before the shrimp go in for that golden color.
- Taste As You Go: Your tongue knows best, so keep tasting and adjusting.
Variations and Substitutions
You can totally make this recipe your own – cooking should be fun, not scary or stressful!
- Switch the Protein: Try chicken, scallops, or even spicy sausage instead of shrimp.
- Change the Pasta: Any shape works, but I love how shells and spirals grab the sauce.
- Add Some Veggies: Bell peppers and spinach make it colorful and healthy.
- Make It Dairy-Free: Coconut cream works great if you can’t do regular cream.
- Control the Heat: Less cayenne for wimps like me, more for fire-breathers.
- Try Different Herbs: Fresh basil or oregano can change the whole flavor game.
Make-Ahead and Storage Tips
Leftovers taste pretty darn good the next day! Put everything in the fridge for up to 3 days in a container with a tight lid.
When you reheat it, add a splash of cream or milk to make it creamy again. The sauce gets thick when it’s cold, so thin it out slowly.
You can freeze portions for about 2 months, but honestly, it tastes best fresh. The cream sauce gets a bit weird after freezing, but it’s still totally edible.
Recipe FAQs
Can I use frozen shrimp for this recipe?
Sure thing! Just thaw them out completely first and pat them dry with paper towels for the best results.
What if I don’t have Cajun seasoning?
No worries! Mix paprika, garlic powder, onion powder, oregano, thyme, cayenne, salt, and pepper – easy peasy!
How do I prevent the sauce from breaking?
Keep your heat low when you add the cheese and whisk like your life depends on it.
Can I make this dish less spicy?
Absolutely! Just use less Cajun seasoning or skip the cayenne pepper – you’re in charge of the heat.
What pasta shapes work best?
Any tube shape, like penne or rigatoni, works great because they catch all that yummy sauce inside.
How do I know when shrimp is cooked?
They turn pink all over and curl up into a cute little C-shape – that’s your cue!
Can I substitute the heavy cream?
Half-and-half works okay, but makes a thinner sauce – just don’t use regular milk or it might curdle.
How long does leftover pasta keep?
Pop it in the fridge for up to 3 days in a sealed container – it reheats pretty well.
Can I add vegetables to this dish?
YES! Bell peppers, spinach, or mushrooms are all fantastic – just cook them first before adding the cream.
What wine pairs well with this pasta?
A crisp white wine like Sauvignon Blanc cuts through all that richness and tastes amazing with the spices.

Creamy Cajun Shrimp Pasta
Ingredients
- 1 pound large shrimp peeled and deveined
- 8 ounces penne pasta
- 1 cup heavy cream
- ½ cup Parmesan cheese freshly grated
- 2 tablespoons Cajun seasoning
- 3 cloves garlic minced
- 1 tablespoon butter
- 1 tablespoon olive oil
- 1 tablespoon kosher salt for pasta water
- ¼ cup fresh parsley chopped
- ½ teaspoon black pepper
Instructions
- Season the Shrimp: Toss shrimp with Cajun seasoning and olive oil until every piece is coated with those amazing spices for maximum flavor.
- Cook the Pasta: Boil pasta in salted water for 8-10 minutes until it's got that perfect bite – not mushy, not crunchy, just right for holding sauce.
- Sear Those Beauties: Cook seasoned shrimp in butter over medium-high heat for 2-3 minutes per side until they're golden brown and absolutely gorgeous to look at.
- Make Creamy Magic: Pour heavy cream into the same pan, scrape up the good stuff, then whisk in ½ cup Parmesan until it's smooth and dreamy.
- Bring It Together: Add your pasta and shrimp back to the pan, toss with the cream sauce, and add pasta water if it needs thinning out perfectly.
- Final Touches: Taste and season with salt and pepper as needed, then top with fresh parsley and extra cheese because more cheese is always the right answer here.
Notes
- Fresh Parmesan from a block melts so much better than the pre-shredded stuff – it’s worth the extra two minutes of grating time, I promise.
- That starchy pasta water is like liquid gold for making your sauce stick to every single noodle – don’t forget to save some before draining.
- Shrimp cook super fast, so don’t walk away from the stove or you’ll end up with little rubber balls instead of tender shrimp.
- Store-bought Cajun seasoning can be really salty, so start with less and add more until it tastes just right for your family’s taste buds.
- This tastes best when it’s piping hot and fresh, so call everyone to the table as soon as you’re done cooking – it’s WORTH IT!
