Cold Chicken Pasta Salad Recipe With Mayo: Creamy Picnic Delight With Garden Veggies

This pasta salad delivers creamy comfort in every bite, perfect for warm-weather gatherings or quick lunches. I developed this recipe to balance rich flavors with fresh garden vegetables, creating a dish that’s both satisfying and refreshing.

The secret lies in the combination of tender chicken, al dente pasta, and a velvety mayo-based dressing that clings to every ingredient. A touch of mustard and lemon juice brightens the richness, while crisp celery and bell peppers add crunch.

After assembling, a short chilling time allows the flavors to meld, transforming simple components into a cohesive, crowd-pleasing salad. The result is a dish that’s as easy to make as it is to enjoy.

Serve it at picnics, potlucks, or as a light dinner. Here’s how to make it perfectly every time.

Ingredients for Cold Chicken Pasta Salad Recipe with Mayo

Nothing exotic here—just good stuff for a creamy, crunchy crowd-pleaser.

The chicken is the foundation—Costco’s pre-cooked rotisserie saves time (shred and go), but poaching your own in salted water keeps it juicy. Elbow macaroni is classic, but cavatappi or farfalle grab dressing better. For the mayo, Hellmann’s or Duke’s give that rich, tangy base. Skip the low-fat versions here (they break down when chilled). Celery and bell peppers? Hit the produce section for the crispest stalks and firmest peppers.

No red onion? Green onions at double the amount work in a pinch. Swap bell peppers for cucumber or cherry tomatoes if that’s what’s in season. Dill haters can use fresh tarragon or chives—different vibe, still bright. The mustard is key for balance, but yellow mustard at the same amount works too. If lemon juice feels fussy, apple cider vinegar adds similar tang. Pasta shape doesn’t matter much (just keep it short).

Best made 4-6 hours ahead so flavors meld. Keeps 3-4 days in the fridge (the pasta soaks up dressing). Don’t freeze—mayo separates, veggies turn mushy. Leftovers? Toss with extra dill or parsley to freshen it up before serving.

Step-by-Step Instructions for Cold Chicken Pasta Salad

Here’s the method I’ve perfected for this creamy, picnic-ready dish packed with garden veggies.

Step 1: Poach and Cool the Chicken Breasts

Fill a large pot with water and bring to a gentle boil. Add the 1.5 lb boneless skinless chicken breasts and reduce heat to maintain a simmer. Cook for 12-15 minutes until the internal temperature reaches 165°F and the meat is no longer pink in the center.

Remove the chicken from the water and let it rest for 5 minutes before shredding or dicing into ½-inch pieces. Spread it on a baking sheet and refrigerate for 20 minutes to cool completely. This prevents the chicken from warming the pasta and keeps everything crisp and fresh.

Step 2: Cook and Cool the Elbow Macaroni

In a large pot of salted boiling water, cook the 12 oz elbow macaroni according to package directions until al dente. Drain immediately and rinse under cold water to stop the cooking process. This removes excess starch and prevents the pasta from turning mushy as it sits.

Spread the pasta on a baking sheet and refrigerate for 15 minutes to cool completely. You want it cold before mixing—warm pasta will melt the mayonnaise and make the salad greasy instead of creamy.

Step 3: Prepare the Garden Vegetables

Finely dice the 3 whole celery stalks, 1 whole red bell pepper, and 1 whole green bell pepper. The pieces should be uniform, about ¼-inch in size, so every bite has a balanced mix of textures. Mince the 0.5 whole red onion finely to distribute its sharp flavor evenly.

Chop the 0.25 cup fresh dill and 0.25 cup fresh parsley, discarding any thick stems. I like to chop the herbs just before adding them to preserve their bright, fresh flavor. This step is where the garden-fresh quality really shines through.

Step 4: Whisk Together the Creamy Dressing

In a large bowl, whisk together the 1.25 cups mayonnaise, 2 tbsp Dijon mustard, 2 tbsp fresh lemon juice, 1 tsp salt, 0.5 tsp black pepper, and 0.5 tsp garlic powder until smooth. The lemon juice cuts through the richness of the mayonnaise, while the Dijon adds a subtle tang.

Taste and adjust seasoning if needed—this is your chance to make sure the dressing has the right balance of creaminess and acidity. The dressing should be thick but pourable, coating the back of a spoon without being gluey.

Step 5: Combine and Chill for Maximum Flavor

In the same large bowl with the dressing, add the cooled chicken, pasta, and all the prepared vegetables. Fold everything together gently with a spatula until evenly coated. Be careful not to overmix—you want the ingredients to stay distinct and fresh-looking.

Cover the bowl and refrigerate for at least 1 hour (I prefer 2 hours if possible). This chilling time allows the flavors to meld together and the pasta to absorb some of the dressing, creating that perfect creamy texture. Serve cold and enjoy the crisp, refreshing crunch in every bite.

Make-Ahead Tips for This cold chicken pasta salad recipe with mayo

Prep Ahead Strategy

I always cook the 1.5 lb chicken breasts and 12 oz pasta the night before. Poach the chicken, cool it, and store in an airtight container. Cook pasta al dente, rinse, and refrigerate separately. This cuts day-of prep to just 20 minutes of chopping and mixing. 💡

Dressing Timing

Whisk the 1.25 cups mayo dressing up to 2 days ahead—the flavors deepen beautifully. Store in a sealed jar in the fridge. The Dijon mustard and lemon juice keep it bright and prevent separation.

Vegetable Prep

Dice the celery, bell peppers, and red onion the morning of serving. They stay crisp for 8-10 hours in the fridge in a sealed container with a damp paper towel. Chop herbs just before mixing to preserve their freshness.

Chilling for Flavor

After combining everything, let it chill for at least 1 hour. For best results, I aim for 4 hours—this allows the pasta to soak up the dressing and the flavors to fully meld. The salad tastes even better the next day. ❄️

Portion Control

Divide into individual containers for grab-and-go lunches. It keeps well for 3-4 days in the fridge. If making for a crowd, keep the dressing separate until 2 hours before serving to maintain optimal texture.

Reviving Leftovers

If the salad seems dry after storage, stir in 1-2 tbsp milk or plain yogurt to restore creaminess. Add extra fresh herbs or a squeeze of lemon to brighten the flavors before serving. 🌿
