Main Courses
This Cajun shrimp pasta salad delivers bold, spicy flavor without overwhelming heat—perfect for pescatarians craving restaurant-quality taste at home. The secret lies in balancing Cajun seasoning with fresh herbs and bright citrus, while crisp-tender shrimp and celery crowns add texture that holds up even after chilling.
I developed this recipe after testing countless versions to get the spice level just right: enough kick to satisfy, but still approachable for family meals.
The dish starts with perfectly cooked shrimp—just 3 minutes in a hot pan with Cajun seasoning creates that signature char while keeping the centers tender.
A creamy, tangy dressing made with Greek yogurt and lime ties everything together, while short pasta shapes like penne or fusilli hold up better than long strands when tossed cold.
The celery crowns (crispy fried or baked) become the star garnish, adding a satisfying crunch that contrasts beautifully with the creamy dressing.
What makes this salad special is how the flavors evolve—best served chilled after at least 1 hour in the fridge, when the shrimp absorbs the dressing and the celery crowns maintain their perfect crunch.
Garnish with fresh parsley, sliced avocado, and a squeeze of lime right before serving to keep everything vibrant. This isn't just a side dish; it's a complete meal packed with protein, fresh vegetables, and that unmistakable Cajun warmth.
Perfect for summer picnics, potlucks, or meal prep—this salad keeps well for 3 days and tastes even better the next day as the flavors meld. The Cajun seasoning can be adjusted to taste, so don't be afraid to experiment with more or less heat to suit your crowd.

Ingredients for cajun shrimp pasta salad
Sixteen ingredients that pack restaurant-style Cajun flavor into every bite—crisp shrimp, creamy dressing, and crunchy celery crowns.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Shrimp (Peeled & Deveined) 🦐 | 1 ½ lb | Wild-caught preferred for flavor |
| Short Pasta (Penne or Fusilli) 🍝 | 12 oz | Cooked al dente, chilled |
| Cajun Seasoning 🌶️ | 2 tbsp | Homemade or Tony Chachere's |
| Greek Yogurt (Plain, Full-Fat) 🧀 | ¾ cup | For creamy dressing base |
| Lemon Juice 🍋 | 3 tbsp | Freshly squeezed for brightness |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High quality for richness |
| Celery Crowns (Fresh) 🧅 | 3 whole | For crispy fried garnish |
| Fresh Parsley 🌿 | ¼ cup | Chopped for garnish |
| Avocado (Ripe) 🥑 | 1 whole | Sliced for garnish |
| Red Bell Pepper 🌶️ | 1 whole | Diced for fresh crunch |
| Garlic Cloves 🧄 | 3 cloves | Minced for dressing |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Vegetable Oil (for frying) 🫒 | 2 cups | For celery crowns |
The shrimp makes or breaks this dish—wild-caught is worth the splurge for that briny sweetness. Trader Joe's or Whole Foods have great frozen options if fresh isn't available. Look for 21-25 count per pound for perfect bite-sized pieces. Cook them exactly 3 minutes in a screaming-hot pan with Cajun seasoning—any longer and they turn rubbery. The pasta? Penne or fusilli hold up best when cold, but avoid anything longer than 1.5 inches. Cook it 1 minute less than package instructions for that perfect al dente bite.
No Cajun seasoning? Mix 1 tbsp each paprika, garlic powder, onion powder, dried thyme, plus 1 tsp cayenne and 0.5 tsp oregano—it's the same magic. The Greek yogurt dressing needs to be thick but pourable—if it's too thin, whisk in 1 tsp cornstarch mixed with cold water. For the celery crowns, cut the base flat so they stand up straight when fried. Avocado should be ripe but firm—squeeze it gently before buying. And if you're short on time, pre-cut veggies from the grocery store still work (just rinse them well).
This salad tastes even better the second day—the shrimp soaks up the dressing and the celery crowns stay crisp. Store everything separately in the fridge: shrimp and pasta in one container, dressing in a jar, and veggies in another. When ready to serve, toss everything together and let it sit for 10 minutes so flavors meld. The celery crowns? Fry fresh or they'll get soggy—keep them in a paper towel-lined basket to stay crisp. Leftovers keep for 3 days and make amazing lunches.

Step-by-step instructions for Cajun shrimp pasta salad
This spicy, creamy, and crunchy pasta salad comes together in layers of bold flavors.
🍳 Step 1: Cook and Chill the Pasta
Bring a large pot of salted water to a rolling boil and cook the 12 oz short pasta (penne or fusilli) until al dente—about 1 minute less than package instructions. Drain immediately and rinse under cold water to stop cooking. Toss with a drizzle of 0.25 cup extra-virgin olive oil to prevent sticking, then spread on a baking sheet and refrigerate for 30 minutes to chill completely.
Chilling the pasta is non-negotiable—it prevents a gummy texture and helps the Cajun shrimp stay warm when mixed later. If you skip this, your salad will turn mushy. Trust me, the wait is worth it for that perfect bite.
🔥 Step 2: Sear the Shrimp with Cajun Spice
Heat 0.25 cup extra-virgin olive oil in a large skillet over medium-high heat until shimmering. Add the 1.5 lb large shrimp and sprinkle with 2 tbsp Cajun seasoning, 1 tsp salt, and 0.5 tsp black pepper. Sear for 2-3 minutes per side until pink and opaque with a golden-brown crust. Transfer to a plate and let rest for 5 minutes before slicing into bite-sized pieces.
Don’t overcrowd the pan—leave space between shrimp so they crisp up instead of steaming. If they release easily from the pan, they’re ready. If not, cook another 30 seconds. The Cajun seasoning should cling like armor, giving every bite that signature kick.
🥘 Step 3: Fry Celery Crowns for Crunch
Cut the 3 whole celery crowns into ¼-inch thick slices (discard the leafy tops). Heat 2 cups vegetable oil in a deep skillet to 350°F. Fry the celery in batches for 1-2 minutes until golden and crispy. Drain on paper towels and sprinkle immediately with 1 tsp salt while hot. Set aside to cool slightly—they’ll crisp up further as they rest.
Frying celery might seem odd, but it transforms this humble veggie into a shatteringly crisp garnish. Keep the oil at 350°F—hotter, and it burns; cooler, and it turns soggy. Work in small batches so the oil doesn’t drop below 340°F, or the celery will absorb oil instead of crisping.
👨🍳 Step 4: Whisk the Creamy Dressing
In a bowl, whisk together the 0.75 cup Greek yogurt, 3 tbsp lemon juice, 0.25 cup extra-virgin olive oil, 3 minced garlic cloves, 1 tsp salt, and 0.5 tsp black pepper until smooth. Taste and adjust seasoning—you want bright, tangy, and just spicy enough to complement the shrimp. Set aside while you prep the remaining ingredients.
This dressing is the soul of the salad. The Greek yogurt keeps it creamy without being heavy, while the lemon juice cuts through the richness. If it’s too thick, whisk in 1-2 tbsp cold water to loosen it. The dressing should coat the back of a spoon but still cling to the pasta.
🥗 Step 5: Assemble and Garnish
In a large bowl, combine the chilled pasta, sliced shrimp, 1 diced red bell pepper, and 0.25 cup chopped fresh parsley. Pour the dressing over everything and toss gently until evenly coated. Fold in the 1 whole avocado, sliced into ¼-inch pieces, and the crispy fried celery crowns just before serving to preserve their crunch.
Let the salad sit for 10 minutes before serving—this gives the flavors time to meld. Garnish each serving with extra chopped parsley and a sprinkle of Cajun seasoning for a pop of color and heat. Serve immediately while the celery is still crisp and the avocado holds its shape.
Pro Tips For Making Cajun Shrimp Pasta Salad
- COOK SHRIMP FAST: Hit the shrimp with a splash of lemon juice and a pinch of salt before hitting the pan—this jumpstarts the cooking and keeps them from curling into sad little question marks. I used to skip this, and half my batch would stick to the pan like it owed me money.
- DON’T BOIL PASTA DRY: Pull the pasta when it’s al dente but still clinging together—about 1 minute early. Toss it straight into the ice bath (cold water + ice cubes) to stop the cooking, then drain thoroughly. Wet pasta makes the salad soggy, and nobody wants a mushy penne party.
- SAVE THE YOGURT FROTH: Stir the Greek yogurt gently with a fork before mixing it into the salad—this breaks up any surface froth, which can make the dressing look unappetizing. I learned this after serving a salad that looked like someone had whipped it with a blender.
- LEMON JUICE FIRST: Add the lemon juice to the yogurt before tossing it with the shrimp and pasta. This brightens the flavor more than if you just drizzle it at the end—think of it like waking up the dish instead of just sprinkling perfume on it. Trust me, your taste buds will notice.
Dietary considerations for this dish
Gluten-Free Adaptation
This salad is naturally gluten-free if you use certified gluten-free Cajun seasoning—brands like Tony Chachere's or Simply Organic make great options. For the pasta, swap regular penne or fusilli for gluten-free short pasta like Barilla GF or De Cecco GF.
Just be sure to check labels for cross-contamination warnings, as some facilities process gluten-containing grains. 🌱
Dairy-Free Option
To make this dish dairy-free, replace the Greek yogurt with full-fat coconut yogurt or a dairy-free mayo (like Hellmann's Vegan). For extra creaminess, blend ½ cup silken tofu with 1 tbsp lemon juice and 1 tbsp olive oil as a substitute.
The texture stays rich, and the tangy brightness remains intact. Always check labels on Cajun seasoning for hidden dairy additives.
Lower-Carb Modifications
For a lower-carb version, reduce the pasta to 6 oz and add 1 cup chopped cauliflower florets (cooked until tender-crisp) to bulk it up. You can also replace the pasta entirely with zucchini noodles (spiralized and sautéed for 1-2 minutes).
The celery crowns and avocado keep it satisfying without the carb overload. 🥦
Spice Sensitivity Adjustments
If you're sensitive to heat, cut the Cajun seasoning to 1 tbsp and add ½ tsp smoked paprika for depth without the burn. For an extra-mild version, use ½ tsp Cajun seasoning and boost flavor with 1 tsp lemon zest and 1 tsp fresh thyme.
Always taste the shrimp after seasoning—it's easier to add more spice than to remove it later.
Allergen-Friendly Swaps
For nut allergies, ensure your Cajun seasoning is nut-free (some blends contain paprika from nut-processing facilities). If you're avoiding seafood, substitute shrimp with chilled grilled chicken breast (cooked to 165°F and sliced).
For a vegan version, replace shrimp with extra-firm tofu (pressed, cubed, and pan-fried in Cajun seasoning) and use vegan mayo in the dressing. 🌿

Frequently asked questions
Can I use frozen shrimp instead of fresh?
Yes! Thaw frozen shrimp completely in the refrigerator overnight (never at room temperature). Pat them dry thoroughly before cooking to get that perfect golden crust. For best results, look for 21-25 count per pound shrimp—they're sized perfectly for this salad. If using pre-cooked frozen shrimp, skip the Cajun seasoning in the pan and toss them with 1 tbsp Cajun seasoning after cooking instead.
How do I adjust the spice level?
The recipe balances 2 tbsp Cajun seasoning for 1.5 lb shrimp—about 1 tbsp per pound—which gives a mild but noticeable kick. For more heat, add an extra ½ tsp cayenne pepper directly to the shrimp while searing. For milder flavor, reduce to 1 tbsp total Cajun seasoning and boost with 1 tsp lemon zest and ½ tsp smoked paprika for depth. Always taste the shrimp after seasoning!
Can I make this salad ahead of time?
This salad tastes even better after chilling for 1-2 hours as flavors meld. Store components separately: pasta and shrimp in one container, dressing in a jar, and veggies in another. When ready to serve, toss everything together and let sit for 10 minutes before garnishing. The celery crowns should be fried fresh or they'll lose crispness—keep them in a paper towel-lined basket until serving.
What's the best pasta shape for this salad?
Short pasta shapes like penne, fusilli, or rotini work best—they hold up better when cold and won't get mushy. Avoid long strands like spaghetti or linguine, which can turn into a sticky mess. For extra texture, try farfalle (bowties) or gemelli (twists). Always cook pasta 1 minute less than package instructions and rinse with cold water immediately after draining to stop cooking.
How do I keep the celery crowns crispy?
Fry the celery crowns in 350°F oil for just 1-2 minutes until golden, then drain on paper towels and season immediately with salt while hot. For extra crispness, sprinkle with 1 tsp cornstarch before frying. Store fried celery crowns in a paper towel-lined container at room temperature—they'll stay crisp for 2 hours. If reheating, warm in a 200°F oven for 5 minutes to revive crispness.
