| Red Onion 🧅 | 1 medium | Thinly sliced, white works too |
| Cajun Seasoning 🌶️ | 2 tbsp | Homemade or store-bought blend |
| Mayonnaise 🥛 | ¾ cup | Full-fat preferred for creaminess |
| Greek Yogurt 🧀 | ½ cup | Plain, full-fat for tang |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed for brightness |
| Olive Oil 🫒 | ¼ cup | Extra-virgin for richness |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |

The chicken is the heart of this dish, so don't skimp on quality. Look for fresh, plump breasts at Whole Foods or your local butcher—they'll stay juicier when grilled. I always marinate mine for at least 30 minutes (overnight if possible) to let those Cajun spices really sink in. For the celery, grab the freshest stalks you can find—bright green and crisp—they'll hold their crunch better after slicing. The pasta? Medium shapes like penne or rotini work best—they hold dressing well without getting mushy. Pro tip: Cook the pasta al dente (1 minute less than package says) so it doesn't turn to mush when tossed with the cold dressing later.
No Cajun seasoning? Mix 1 tbsp each paprika, garlic powder, onion powder, dried thyme, and a pinch of cayenne—boom, instant homemade blend. Swapping the mayo? Greek yogurt works 1:1 for a lighter option (just add an extra tbsp of lemon juice). The red bell pepper and onion can be swapped for whatever you've got—green peppers or shallots both work beautifully. For extra crunch without celery, try diced jicama or radishes. If you're making this ahead, assemble everything except the celery crowns—add those fresh just before serving so they stay crisp. The hot sauce is totally optional, but trust me, a little goes a long way for that perfect spicy kick.
This salad tastes even better the next day—flavors meld perfectly when chilled overnight. Store in an airtight container with parchment between layers to keep everything fresh. Keeps 4-5 days in the fridge, though I usually eat it up within 2 days. For meal prep, I double the recipe and portion it into glass containers with snap-lids—makes lunches easy all week. The celery crowns will soften faster, so add those fresh when you're ready to eat. Freezes surprisingly well too (minus the celery)—3 months max for the base salad without dressing.

Just toss the cooked chicken, pasta, and chopped veggies into a bowl—no separate boiling, no sticky mess—while the Cajun seasoning works its flavor magic in minutes. Honestly, I’ve made it while scrolling through my phone.

Step-by-step instructions for Cajun chicken pasta salad
Here's how to make this spicy, creamy pasta salad with crisp celery crowns.
Cook the Chicken and Marinate It
Cut the 2.5 lb boneless chicken breast into bite-sized pieces and place them in a large bowl. In a small bowl, whisk together the 0.25 cup olive oil, 2 tbsp lemon juice, 4 minced garlic cloves, 2 tbsp Cajun seasoning, 1 tsp salt, 0.5 tsp black pepper, and 1 tbsp hot sauce (if using). Pour this marinade over the chicken and toss to coat evenly.
Let the chicken marinate for at least 15 minutes while you prepare the rest of the ingredients. This step infuses the chicken with bold Cajun flavors and tenderizes it for perfect texture. If you have more time, marinate for up to 1 hour in the refrigerator for deeper flavor.
Heat a large skillet over medium-high heat and add the chicken pieces in a single layer. Cook for 5-6 minutes per side, or until the chicken reaches an internal temperature of 165°F and is no longer pink in the center. The chicken should be fully cooked but still juicy. Transfer the cooked chicken to a cutting board and let it rest for 5 minutes before chopping into bite-sized pieces.
Cook the Pasta and Prepare Vegetables
While the chicken cooks, bring a large pot of salted water to a rolling boil. Add the 1.5 cups medium pasta and cook according to package instructions until al dente. Drain the pasta and rinse it under cold water to stop the cooking process and cool it down. This prevents the pasta from becoming mushy in the salad.
While the pasta cooks, prepare the vegetables. Thinly slice the 3 whole celery stalks into crowns (about 1/4-inch thick slices). Dice the 1 medium red bell pepper into small pieces and thinly slice the 1 medium red onion. Chop the 0.25 cup fresh parsley finely. Set all the vegetables aside until ready to use.
Make the Creamy Cajun Dressing
In a medium bowl, combine the 0.75 cup mayonnaise, 0.5 cup Greek yogurt, 1 tbsp lemon juice, 1 tsp salt, and 0.5 tsp black pepper. Mix until smooth and creamy. This dressing is the heart of your pasta salad, balancing the spicy Cajun flavors with a cool, tangy creaminess. If you prefer a thicker dressing, you can chill it for 15 minutes before using.
Add the chopped parsley to the dressing and mix well. The parsley adds a fresh, bright note that cuts through the richness of the mayonnaise and yogurt. Taste the dressing and adjust seasoning if needed—add more Cajun seasoning for extra heat or more lemon juice for brightness.
Assemble the Pasta Salad
In a large mixing bowl, combine the cooked and chopped chicken, drained pasta, diced red bell pepper, sliced red onion, and celery crowns. Pour the dressing over the mixture and gently toss everything together until the pasta and vegetables are evenly coated. The celery crowns should stay crisp, so handle them gently to avoid bruising.
Let the salad sit for 10-15 minutes before serving. This allows the flavors to meld together and the dressing to soak into the pasta and chicken. If you're serving it immediately, give it a final toss to distribute the dressing evenly. The salad should be creamy, spicy, and full of texture from the crisp celery crowns.
Serve and Enjoy
Transfer the pasta salad to a serving dish and garnish with additional chopped parsley and celery crowns if desired. Serve immediately while the chicken is still warm and the celery crowns are crisp. This salad is perfect for picnics, potlucks, or a hearty lunch with a side of crusty bread.
For extra crunch, you can lightly toast the celery crowns in a dry skillet over medium heat for 1-2 minutes per side before adding them to the salad. This step adds a delightful contrast to the creamy, spicy flavors. Store any leftovers in an airtight container in the refrigerator for up to 3 days, though it's best enjoyed fresh.
Pro Tips For Making Cajun Chicken Pasta Salad
- BRINE THE CHICKEN: Toss those chicken breasts in ice water with 1 tablespoon salt per cup of water for 20 minutes before cooking—it stays juicy, even when tossed in spicy Cajun seasoning. I learned this the hard way after serving dry, over-seasoned chicken that fought with the pasta for attention.
- COOK PASTA AL DENTE: Pull the pasta out before it’s fully tender—test a piece, then wait 30 seconds to let it firm up in the salad. Overcooked pasta turns mushy when mixed with cold chicken and veggies, and nobody wants sad, limp noodles in their Cajun feast.
- DICE VEGETABLES SMALL: Cut celery, bell pepper, and onion into ¼-inch pieces—they’ll soften as the salad sits, but you still want texture, not a watery mess. I used to chop them big for "presentation," but the salad just got soggy faster.
- MIX DRESSING LAST: Toss the warm chicken and drained pasta with half the dressing, then fold in the veggies and remaining dressing right before serving. This keeps the celery crisp and the bell pepper from turning into a sad, limp garnish. (Yes, I’ve seen it happen.)
Creative variations of this dish
Spicy Shrimp Twist
Swap the chicken for 1.5 lbs peeled and deveined shrimp—toss them in the same Cajun marinade for just 10 minutes before grilling or sautéing. Cook shrimp over medium-high heat for 2-3 minutes per side until they turn pink and opaque.
The shrimp add a lighter texture but keep that bold Cajun flavor. I love serving this version with lemon wedges on the side for extra zing. 🌶️
Smoky BBQ Chicken
Replace the Cajun seasoning with 2 tbsp smoked paprika and 1 tbsp brown sugar for a sweet-savory BBQ twist. Use ½ cup BBQ sauce**> in the dressing instead of hot sauce, and add ¼ cup chopped red onion for extra depth.
This version has a caramelized, smoky profile that pairs perfectly with cornbread. I first tried this at a Georgia tailgate and it became an instant crowd favorite. 🔥
Mediterranean Herb Version
Swap the Cajun seasoning for 1 tbsp dried oregano, 1 tsp dried basil, and ½ tsp dried thyme. Add ½ cup chopped kalamata olives and ¼ cup crumbled feta cheese to the salad.
Use ½ cup Greek yogurt and 2 tbsp lemon juice for the dressing—this creates a bright, herby flavor that's perfect for summer gatherings. The olives and feta add a salty contrast to the creamy dressing. ✨
Extra Crunch Add-Ins
For maximum crunch, add ½ cup toasted pecans or walnuts (toasted in a dry skillet for 3-4 minutes) or ½ cup crispy fried shallots. Both work beautifully—pecans add a buttery richness while fried shallots bring an Asian-inspired crunch.
I like toasting the nuts or shallots right before serving so they stay fresh. 💫
Slow-Cooker Chicken
For hands-off cooking, marinate the chicken as directed, then transfer it to a slow cooker with 2 tbsp olive oil and 1 tbsp apple cider vinegar. Cook on low for 4-5 hours or high for 2-3 hours until the chicken shreds easily.
This method keeps the chicken incredibly tender and juicy—perfect for busy weeknights. The slow-cooked chicken absorbs even more of the Cajun flavors. 🍗
Sweet Potato Swap
Replace half the pasta with 1 cup cooked and cooled sweet potato cubes (roasted at 400°F for 20 minutes with 1 tsp smoked paprika). The natural sweetness balances the spicy Cajun kick beautifully.
I also add ¼ cup chopped cilantro to the dressing for a fresh, slightly sweet contrast. This version has a heartier texture and deeper flavor profile. 🌟

Frequently asked questions
Can I make this pasta salad ahead of time?
This salad actually tastes better the next day as the flavors meld together. Assemble everything except the celery crowns (add those fresh before serving) and store in an airtight container in the fridge for up to 5 days. The chicken stays juicy and the dressing soaks into the pasta perfectly overnight.
How can I make this salad spicier? Add 1-2 extra tablespoons of Cajun seasoning to the chicken marinade and dressing, or stir in 1 tablespoon of hot sauce when tossing everything together. For heat lovers, try adding ½ teaspoon of cayenne pepper to the dressing.
What's the best pasta shape for this recipe?
Medium shapes like penne, rotini, or fusilli work best—they hold the creamy dressing well without getting mushy. Avoid long, thin pasta like spaghetti, which can become tangled. If you prefer a lighter texture, try whole wheat or chickpea pasta for added protein and fiber.
Can I use rotisserie chicken instead of fresh?
Yes! Rotisserie chicken works perfectly—just shred or chop 2.5 cups of cooked chicken (about 2-3 cups from a store-bought rotisserie). Skip the marinating step and season the chicken directly with 1 tablespoon of Cajun seasoning before mixing it into the salad. This saves time while keeping great flavor.
How do I keep the celery crowns crisp?
Add the celery crowns fresh just before serving to maintain their crunch. If making ahead, store them separately in the fridge and toss them in only when ready to eat. For extra crispness, lightly toast them in a dry skillet for 1-2 minutes before adding to the salad.
