Cold Pasta Salad Recipe With Mayonnaise: Al Dente Noodles and Creamy Herb Bliss

This cold pasta salad recipe with mayonnaise transforms simple ingredients into a creamy, herby masterpiece that keeps beautifully for days. 💛 The secret lies in al dente pasta and a perfectly balanced dressing that coats every noodle without overpowering the fresh vegetables and protein.

I developed this recipe after years of picnic disappointments—no more soggy pasta or bland flavors.

What sets this salad apart is the foolproof technique for achieving that signature creamy texture while keeping the pasta from turning mushy. We'll use a 50/50 ratio of mayonnaise to buttermilk for richness without heaviness, then boost it with fresh herbs, lemon juice, and a touch of Dijon mustard.

The key is letting everything chill for at least 30 minutes before serving—this allows flavors to meld and the pasta to absorb the dressing perfectly.

By the time you're ready to serve, you'll have a restaurant-quality dish with tender al dente noodles, crisp vegetables, and a velvety herb dressing that ties everything together. It's substantial enough to serve as a main dish for picnics or potlucks, yet light enough for a summer lunch.

The best part? It tastes even better the next day, making it perfect for meal prep.

Whether you're hosting a backyard barbecue or packing lunches for the week, this pasta salad delivers consistent, crowd-pleasing results. The recipe scales easily for any gathering size, and the components can be prepped ahead of time—just assemble when ready to serve.

Ingredients for cold pasta salad recipe with mayonnaise

These 14 ingredients create the creamiest, most satisfying cold pasta salad you'll ever make.

The pasta is non-negotiable—De Cecco or Barilla cook up perfectly al dente every time. Grab medium penne for that classic bite and texture. For the mayo, Duke's or Hellmann's are my go-tos—they're stable and won't separate. Fresh herbs? Trader Joe's has the best pre-washed bundles, but if you're growing your own, dill and parsley are the stars here. The red bell pepper should be vibrant, not waxy—look for the thickest ones at Whole Foods or your local farmers market.

No buttermilk? Substitute 1 cup plain yogurt plus 1 tsp lemon juice—it's a perfect swap. Fresh herbs wilt fast, so chop them last if prepping ahead. The eggs can be dyed or plain, but avoid pre-cooked jarred eggs—they're rubbery. For extra richness, add 1/4 cup crumbled feta (optional but divine). If you're watching calories, use light mayo and reduce the olive oil to 1 tbsp. The celery? Don't skip the core—it's the most flavorful part!

This salad gets better as it chills—4-5 hours is ideal. Store in an airtight container with parchment between layers to prevent sogginess. Keeps 4 days in the fridge, and freezes beautifully for 2 months (though texture changes slightly). I always make a double batch—one for dinner, one for lunches. The dressing separates slightly when refrigerated? Just whisk it back together before serving.

Step-by-step instructions for creamy herb pasta salad

Here's how to create a velvety, herb-infused pasta salad that stays creamy all day long.

Bring a large pot of water to a rolling boil and add 1.5 lbs medium penne pasta, along with 1.5 tsp salt. Cook until al dente—about 1 minute less than package instructions. You want the pasta to have a slight bite when you bite into it.

Drain immediately and rinse under cold water for 30 seconds to stop the cooking process. Spread the pasta on a baking sheet and let it cool completely at room temperature. This prevents a gummy texture in your final salad. I like to fan it out in a single layer so it cools evenly.

In a medium bowl, whisk together the 1 cup mayonnaise, 1 cup buttermilk, 0.5 cup lemon juice, and 1 tbsp Dijon mustard until perfectly smooth. This creamy base is what makes this salad truly special—it stays luscious even after hours in the fridge.

Next, fold in the chopped herbs: 0.33 cup fresh dill, 0.25 cup fresh chives, and 0.25 cup fresh parsley. I like to chop the herbs finely so they distribute evenly throughout the salad. Taste the dressing and adjust seasoning with 0.5 tsp black pepper—this is where the magic happens!

In a large mixing bowl, combine the cooled pasta with the creamy herb dressing. Add the diced 1 whole red bell pepper and 2 whole celery stalks, which should be chopped into small, uniform pieces. The crunch from these vegetables contrasts beautifully with the creamy pasta.

Gently fold everything together using a large spoon or your hands. You want to distribute the dressing evenly without mashing the pasta. Here's the thing—don't overmix or the pasta will turn mushy. A few small lumps are actually preferable for texture.

Chop the 6 whole hard-boiled eggs into small pieces and add them to the pasta mixture. The eggs add a wonderful protein boost and keep the salad satisfying. Drizzle in the 2 tbsp olive oil and toss everything together one final time.

Let the salad sit for 10-15 minutes before serving. This gives the flavors time to meld together beautifully. If you're serving it immediately, give it a final toss to distribute everything evenly. The salad should be creamy, herby, and packed with texture from the fresh vegetables and eggs.

Transfer the pasta salad to an airtight container and refrigerate for at least 1 hour before serving. This chilling time allows the flavors to develop fully and the dressing to absorb into the pasta perfectly. The longer it sits, the better it gets—this salad actually improves overnight!

When ready to serve, give it one final toss and taste. Adjust seasoning if needed—sometimes the flavors intensify after chilling. Serve it chilled as a main dish or side for picnics, barbecues, or summer gatherings. Each bite should deliver that perfect balance of creamy, herby, and slightly tangy flavors.

Perfect pairings for this cold pasta salad recipe with mayonnaise

Picnic Perfection

This creamy pasta salad is a picnic staple for good reason—it stays fresh in a cooler for 4-6 hours without wilting. Pack it in a wide-mouth mason jar with the dressing on top to prevent sogginess.

I like to bring it alongside grilled chicken or steak for a complete meal. For extra convenience, pre-chop all veggies and store them separately until assembly day. 🧺

BBQ Sidekick

Serve this salad as a cool contrast to smoky meats at your next cookout. The herby mayo dressing complements grilled ribeye steaks or pulled pork beautifully. For a showstopper, arrange it in a hollowed-out watermelon bowl with fresh mint leaves on top.

The juicy sweetness of the watermelon cuts through the richness of the pasta. 🍉

Summer Potluck Star

This dish is a crowd-pleaser at summer gatherings because it's easy to transport and eat. Bring it in a large glass bowl for easy serving—guests can scoop directly from the container. For a festive touch, garnish with edible flowers like nasturtiums or pansies.

The vibrant colors make it look as good as it tastes. I always double the recipe for potlucks—it disappears fast! 🌸

Lunchbox Hero

Pack individual portions in glass containers with snap-on lids for meal prep. The creamy texture holds up well overnight, and the flavors only get better. Add a side of whole-grain crackers or crusty bread for dipping.

For kids, serve with cherry tomatoes and cucumber slices on the side. The bright colors make it more appealing for little ones. 🧺

Dinner Party Elevation

Transform this salad into an elegant appetizer by arranging it in a ring mold and slicing into perfect rounds. Garnish with microgreens or a drizzle of truffle oil for a gourmet touch.

Serve with chilled sparkling water and light bites like bruschetta for a sophisticated spread. The creamy texture pairs perfectly with crisp white wines like Sauvignon Blanc. 🍷

Flavor Boosters

Want to customize? Add ½ cup crumbled feta for tangy brightness or ¼ cup chopped sun-dried tomatoes for Mediterranean flair. For a smoky twist, stir in 1 tbsp smoked paprika with the dressing. The possibilities are endless—let your taste buds guide you! 🌶️
