This chicken pasta salad recipe with poppy seed dressing transforms a simple lunch into a restaurant-worthy meal. The secret lies in perfectly grilled chicken and a creamy dressing that balances tangy mustard with nutty poppy seeds—creating a texture that's both velvety and satisfying.
I've perfected this dish over years of picnic lunches and office potlucks, where it consistently disappears first.
The foundation starts with high-quality rotisserie chicken or grilled breast, sliced into bite-sized pieces for even distribution. Cooking the pasta al dente ensures it holds up when tossed with the dressing, while the poppy seed mixture adds a luxurious crunch that elevates every bite.
This isn't your average pasta salad—it's a harmonious blend of protein, caramelized onions, and fresh herbs that keeps well for days.
What makes this recipe stand out is the dressing, where mayonnaise meets Dijon mustard and fresh lemon juice, then gets a nutty upgrade from ground poppy seeds.

Ready in just 30 minutes, this dish delivers restaurant-quality results without the fuss. The key is letting the flavors meld in the refrigerator for at least an hour before serving—this allows the dressing to fully coat the ingredients, creating that signature creamy harmony.

Ingredients for chicken pasta salad recipe with poppy seed dressing
Sixteen ingredients blend perfectly for a restaurant-style pasta salad with nutty crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Cooked Chicken Breast 🍗 | 2 cups | Diced, skinless, cooked and chilled |
| Short Pasta 🍝 | 12 oz | Rotini or fusilli preferred |
| Red Onion 🧅 | ½ cup | Thinly sliced, caramelized preferred |
| Celery Stalks 🥬 | 2 whole | Diced, fresh and crisp |
| Fresh Parsley 🌿 | ¼ cup | Chopped, flat-leaf preferred |
| Poppy Seeds 🌰 | ¼ cup | Ground or whole, toasted |
| Mayonnaise 🥫 | ¾ cup | High-quality, full-fat preferred |
| Dijon Mustard 🍯 | 2 tbsp | Mild or strong, to taste |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed, bright flavor |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for richness |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Garlic Cloves 🧄 | 2 cloves | Minced, fresh preferred |
| Red Wine Vinegar 🍷 | 1 tbsp | For tangy brightness |
The chicken is the star here—rotisserie chicken from Whole Foods or Trader Joe's gives the best flavor, but grilled breast works too. Look for high-quality, fresh chicken with good marbling for juiciness. If using pre-cooked rotisserie, shred it yourself for better texture. The pasta should be cooked al dente—undercooked pasta gets mushy when tossed with dressing, while overcooked pasta loses its bite. Short shapes like rotini or fusilli hold dressing beautifully, but penne or farfalle work too. For the poppy seeds, Bob's Red Mill or Trader Joe's carry excellent ground poppy seeds that toast beautifully in a dry pan for 2-3 minutes—just until fragrant.
No poppy seeds? Toasted pine nuts or walnuts add a similar crunch, though the flavor differs slightly. Fresh parsley wilting? Dried parsley at half the amount works in a pinch, but fresh is ideal. The mayonnaise matters here—Duke's or Hellmann's are reliable, but avoid low-fat versions. For extra richness, blend in 1 tablespoon of Greek yogurt. The Dijon mustard can be swapped for whole-grain mustard if you prefer a grainier texture. If you're avoiding vinegar, extra lemon juice brightens the dressing nicely. The caramelized onions? Quick tip: cook them low and slow with a splash of water to prevent burning—worth the extra 10 minutes for that sweet depth.
This salad tastes even better the next day as flavors meld. Store in an airtight container in the fridge for up to 4 days. The dressing separates slightly but mixes right back up. For meal prep, portion into individual containers—perfect for lunches. If making ahead, hold off on adding the dressing until just before serving to keep the pasta crisp. The poppy seeds stay fresh for 6 months in a sealed container, so buy extra. The chicken keeps well for 3 days in the fridge, so use it first or freeze for up to 3 months.

Step-by-step instructions for chicken pasta salad with poppy seed dressing
Here's how to assemble a perfectly balanced pasta salad with nutty depth and creamy richness.
👨🍳 Step 1: Cook and Cool the Pasta
Bring a large pot of salted water to a rolling boil and cook the 12 oz short pasta according to package instructions until al dente. I like to undercook it by 1 minute—it'll finish cooking in the dressing. Drain immediately and rinse under cold water to stop the cooking process and remove excess starch.
Transfer the pasta to a large mixing bowl and let it cool completely to room temperature. This cooling step is crucial—warm pasta will make your dressing watery. Spread it on a baking sheet and refrigerate for 15 minutes if needed to speed up the process. Cool pasta also helps the flavors meld better when you add the dressing later.
🍳 Step 2: Prepare the Vegetable Medley
In a medium bowl, combine the 0.5 cup thinly sliced red onion and 2 whole celery stalks, diced into ¼-inch pieces. Add the 0.25 cup chopped fresh parsley and toss everything gently. This mix should be ready to go—no need to chop anything else. The onion adds a subtle sweetness, celery provides crunch, and parsley brings freshness that balances the rich dressing.
If you have time, caramelize the red onion first by cooking it in a dry skillet over medium-low heat for 8-10 minutes until golden. This step adds depth, but it's optional—raw onion works perfectly fine too. The celery should stay crisp, so don't overcook it. Add this vegetable mixture to the cooled pasta and toss lightly to combine.
👨🍳 Step 3: Make the Poppy Seed Dressing
In a separate bowl, whisk together the 0.75 cup mayonnaise, 2 tbsp Dijon mustard, 2 tbsp lemon juice, 2 tbsp olive oil, 1 tbsp red wine vinegar, 1 tsp salt, and 0.5 tsp black pepper. The lemon juice and vinegar add brightness that cuts through the richness of the mayonnaise, while the mustard provides a subtle tang.
Add the 2 cloves minced garlic and 0.25 cup poppy seeds to the dressing mixture. I like to toast the poppy seeds first in a dry skillet over low heat for 2 minutes until fragrant—this enhances their nutty flavor. Whisk everything together until smooth and well combined. The dressing should be thick but pourable—if it's too thick, add 1-2 teaspoons of water to loosen it.
🥘 Step 4: Combine Everything and Chill
Add the dressing to the pasta and vegetable mixture in the large bowl. Gently fold everything together with a wooden spoon or clean hands, being careful not to break the pasta strands. The goal is to distribute the dressing evenly without mashing the ingredients. Add the 2 cups diced cooked chicken breast and fold it in last—this keeps the chicken warm and tender.
Transfer the salad to an airtight container and refrigerate for at least 1 hour before serving. This chilling time allows all the flavors to meld together perfectly. The longer it sits, the better it tastes—flavors develop and the poppy seeds soften slightly, creating that perfect nutty crunch in every bite. Serve chilled or at room temperature for the best texture and flavor balance.
⏰ Step 5: Serve with Garnish and Enjoy
Before serving, give the salad one final toss to redistribute any dressing that may have settled. Garnish with an extra sprinkle of poppy seeds and a few chopped parsley leaves for freshness. The poppy seeds add a delightful crunch that contrasts beautifully with the creamy dressing and tender pasta.
This chicken pasta salad keeps well in the refrigerator for up to 3 days, making it perfect for meal prep. The flavors only improve over time as the dressing penetrates the pasta and chicken. Serve it at picnics, potlucks, or as a light lunch with a side of crusty bread or a simple green salad. The combination of creamy, nutty, and fresh elements makes this dish incredibly versatile and satisfying.
Pro Tips For Making Chicken Pasta Salad Recipe With Poppy Seed Dressing
- Dry the pasta well: I used to skip this step, but damp pasta turns your salad into a mushy mess—especially with a creamy poppy seed dressing. Toss freshly cooked pasta in a colander with a handful of ice cubes for 30 seconds, then shake it dry. The starch clings to the ice, and your salad stays crisp.
- Shred chicken against the grain: Chicken breast fibers run one way, and if you slice with them, you’ll end up with chewy, uneven strands. Look for the grain direction (it’s usually diagonal), then cut perpendicular. For even faster results, pulse cooked chicken in a food processor with a fork—just don’t overdo it, or you’ll get paste.
- Soak red onion in ice water: Raw red onion tastes harsh and burns your mouth, especially in a cold salad. Thinly slice it, then soak in ice water for 10 minutes before draining. The acidity mellows out the bite, and the cold shock keeps it crisp. (Yes, even if you’re impatient—trust me.)
- Make dressing last longer: Poppy seed dressing separates if you mix it too early or store it wrong. Whisk it cold, then hold off on adding the chicken or pasta until right before serving. If you need to prep ahead, store the dressing and salad separately in airtight containers—combine them only when ready to eat. The texture stays smooth, not greasy.
Serving suggestions for this recipe
Picnic Perfection
Transform this pasta salad into a showstopper picnic dish by packing it in mason jars with layers for easy transport. Start with the dressing at the bottom, followed by pasta, chicken, and veggies.
Seal tightly and store upright in a cooler with ice packs. When ready to serve, simply invert the jar over a plate—no mixing required! 🧺
Bread Pairings
Serve alongside crusty Italian bread or garlic focaccia for dipping. I love using Eataly's Rosemary Focaccia—its herby crust complements the salad's nutty dressing beautifully. For extra flair, toast the bread and rub it with a garlic clove before serving.
The warm bread soaks up any leftover dressing, making every bite satisfying.
Light Lunch Upgrade
Turn this into a complete meal by adding a side of mixed greens with a balsamic vinaigrette. The bright acidity of the dressing cuts through the richness of the pasta salad.
For extra protein, include grilled shrimp skewers or smoked salmon slices. The contrast of textures and temperatures makes this a restaurant-worthy lunch. 🍽️
Party Platter Idea
For gatherings, serve this salad in a large glass bowl with a sprinkle of extra poppy seeds and chopped parsley on top. Add cherry tomatoes and cucumber slices around the edges for a colorful border.
Guests can scoop portions directly from the bowl, making it perfect for buffet-style events. The poppy seed dressing adds a sophisticated touch that impresses every time.
Meal Prep Hack
Divide the salad into individual portion containers for easy grab-and-go lunches. Store the dressing separately and mix just before eating to keep the pasta crisp. I use Glasslock containers because they’re airtight and stackable.
Label with the date—this salad tastes even better the next day as flavors meld. Perfect for office lunches or weekend outings without the fuss. ⏰
Dessert Twist
Yes, you read that right! Use the leftover poppy seed dressing as a drizzle for fruit salad. Toss berries, sliced peaches, and mint leaves with a light drizzle of the dressing.
The nutty sweetness pairs surprisingly well with juicy fruit. It’s a refreshing way to repurpose leftovers into a light dessert or after-dinner treat. 🍓

Frequently asked questions
Can I use rotisserie chicken instead of cooked chicken breast?
Rotisserie chicken is perfect for this recipe—it's already seasoned and shreds easily. Just remove the skin and any large bones, then measure out 2 cups of diced chicken. The flavor will be even richer than with plain breast meat, and it saves you time. Look for high-quality rotisserie chicken from stores like Whole Foods or Trader Joe's for the best results.
What can I substitute for poppy seeds if I don't have any?
Toasted pine nuts or walnuts work beautifully as substitutes for poppy seeds. Use about ¼ cup of nuts instead, and toast them first in a dry skillet for 2-3 minutes until fragrant. For a seed alternative, try sesame seeds or flaxseeds, though they'll have a different flavor profile. If you want to skip nuts entirely, add an extra 1 tablespoon of Dijon mustard for depth.
How long should I let the pasta salad sit before serving?
For the best flavor, let the salad chill in the refrigerator for at least 1 hour before serving. This allows the dressing to fully coat the pasta and chicken, creating that signature creamy harmony. If you have time, 2-3 hours is even better—the flavors meld together perfectly. The longer it sits, the better the texture becomes as the poppy seeds soften slightly while maintaining their crunch.
Can I make this pasta salad ahead of time for a party?
This recipe is perfect for meal prep! Assemble the salad completely (including dressing) and store it in an airtight container in the fridge for up to 3 days. The flavors actually improve over time. For parties, keep the dressing separate until just before serving to maintain the pasta's crispness. Portion into individual containers for easy grab-and-go servings, or serve family-style in a large bowl with extra poppy seeds and parsley on top.
Why does my dressing look separated after chilling?
This is completely normal—the mayonnaise-based dressing naturally separates when chilled. Simply give it a good stir before serving, and it will come back together smoothly. To prevent excessive separation, make sure your mayonnaise is at room temperature before mixing, and avoid adding too much liquid. If the dressing is still too thick, add 1 teaspoon of water or lemon juice at a time until it reaches the right consistency.
