Cold Chicken Pasta Salad Recipe With Mayo and Grapes: Sweet and Creamy Picnic Favorite

I’ve got the perfect picnic dish that’s as easy to make as it is to love. This chilled salad brings together tender chicken, al dente pasta, and juicy grapes in a creamy mayo dressing that’s pure comfort in every bite.

What makes it special? The sweet grapes balance the savory chicken and pasta, while the mayo base keeps everything rich and satisfying. It’s the kind of dish that gets better as it sits, letting all the flavors meld together.

Prep it ahead for stress-free entertaining or a no-fuss lunch. The textures stay spot-on—creamy, crunchy, and tender all at once.

Pack it for your next gathering or keep it in the fridge for quick meals all week. It’s a crowd-pleaser every time.

Ingredients for Cold Chicken Pasta Salad Recipe with Mayo and Grapes

Pantry staples meet picnic perfection with juicy grapes and creamy dressing.

The chicken is the foundation here. Costco’s rotisserie chicken saves time (just shred and go), but poaching your own breasts in seasoned broth gives the juiciest result. For the grapes, red seedless are classic, but green work too—just halve them so every bite has a pop of sweetness. The pasta shape matters: rotini or fusilli hold the dressing best (those nooks and crannies catch all the creaminess).

No sour cream? Greek yogurt works at a 1:1 swap. Out of dill? Fresh parsley or tarragon add a different but great twist. The celery and bell pepper give that essential crunch—cucumber or jicama can stand in if that’s what you’ve got. For a lighter version, swap half the mayo with Greek yogurt, but know the texture will be slightly less rich.

This keeps beautifully—actually improves overnight as flavors meld. Store covered in the fridge for up to 4 days. Don’t freeze it (the mayo separates). Pack it in a cooler with ice packs for picnics—tastes best chilled but not ice cold.

Step-by-Step Instructions for Cold Chicken Pasta Salad With Mayo and Grapes

Here’s the method I use to achieve that perfect creamy texture with just the right balance of sweet and savory.

Step 1: Cook and Cool the Chicken and Pasta

Start by cooking the 1.5 lb boneless skinless chicken breasts. I prefer poaching in lightly salted water for 15-18 minutes until the internal temperature reaches 165°F—this keeps the chicken moist and perfect for dicing. Once cooked, let it cool completely before shredding or dicing into bite-sized pieces.

While the chicken cooks, boil the 12 oz rotini or fusilli pasta in salted water until al dente (about 1 minute less than package directions). Drain, rinse under cold water to stop the cooking process, and let it cool completely. Cool ingredients ensure your salad stays fresh and doesn’t get soggy.

Step 2: Prepare the Vegetables and Grapes

Wash and halve the 2 cups red seedless grapes—this makes them easier to eat and releases some of their sweet juices into the salad. Finely dice the 1 cup celery and 0.5 cup green bell pepper for a consistent texture. For the 0.25 cup red onion, I soak it in cold water for 10 minutes to mellow its sharpness, then drain well before adding.

This prep work ensures every bite has a perfect mix of textures and flavors. The crunch from the celery and bell pepper balances the softness of the pasta and chicken beautifully, while the grapes add bursts of sweetness.

Step 3: Make the Creamy Dressing

In a large bowl, whisk together the 1 cup mayonnaise, 0.5 cup sour cream, 1 tbsp Dijon mustard, 1 tbsp apple cider vinegar, 1 tbsp granulated sugar, 1 tsp salt, and 0.5 tsp black pepper until smooth. The vinegar and mustard brighten the richness of the mayo and sour cream, while the sugar enhances the natural sweetness of the grapes.

Stir in the 2 tbsp fresh dill last—this herb adds a fresh, slightly tangy note that ties all the flavors together. Taste and adjust seasoning if needed, but remember the flavors will meld and intensify as the salad chills.

Step 4: Combine All Ingredients

Add the cooled chicken, pasta, grapes, celery, bell pepper, and drained red onion to the bowl with the dressing. Gently fold everything together with a large spoon or spatula until evenly coated. Be careful not to overmix—you want to keep the ingredients intact and the texture appealing.

I like to let the salad sit for 15-20 minutes at room temperature before serving. This gives the flavors a chance to marry and the pasta time to absorb some of the creamy dressing. For the best results, cover and refrigerate for at least 1 hour before serving to let the flavors fully develop.

Step 5: Serve and Enjoy

Give the salad a final gentle stir before serving to redistribute the dressing. This dish tastes even better the next day, as the flavors continue to deepen. Serve it chilled for a refreshing, creamy picnic or potluck dish that everyone will love.

Garnish with extra fresh dill if desired, and enjoy the perfect harmony of creamy, sweet, and savory in every bite.

Storing and Reheating This Dish

Refrigerator Storage

Transfer your salad to an airtight container once fully chilled. I use glass containers with snap-tight lids to keep everything fresh. Store in the fridge at 40°F or below for up to 4 days. The flavors actually improve overnight as they meld together. ❄️

Preventing Sogginess

To keep the pasta from absorbing too much dressing, I store any leftover dressing separately in a small jar. If the salad looks dry when you go to serve it, just stir in a spoonful or two of the reserved dressing. This keeps the texture perfect for the entire 4-day window.

Freezing Not Recommended

I don’t recommend freezing this salad because the mayonnaise can separate and the grapes and celery will turn mushy when thawed. The texture just isn’t the same after freezing. Stick to refrigeration for the best quality.

Picnic Packing Tips

For picnics, pack the salad in a well-insulated cooler with plenty of ice packs. It’s best served chilled but not ice cold—so take it out of the cooler about 30 minutes before serving. Use a large, shallow container to make serving easier. 💡

Reviving Leftovers

If your salad sits in the fridge for more than 24 hours, give it a good stir before serving. The pasta tends to soak up dressing over time. You can add a splash of milk or a spoonful of mayonnaise to refresh the creaminess if needed.

Make-Ahead Convenience

This dish is perfect for making ahead—prep it the night before your event for the best flavor. Just be sure to keep it refrigerated until serving time. The grapes stay juicy, the pasta stays tender, and the flavors only get better with time.
