Pasta Salad For A Crowd

There’s something about a giant bowl of pasta salad—glistening spirals, bright cherry tomatoes, crisp cucumbers, ribbons of purple onion, and specks of fresh herbs—that makes a table feel instantly festive.

This is a revitalizing, make-ahead dish that comes together quickly, then chills while you do everything else.

It’s perfect for hosts who need a reliable crowd-pleaser, busy families heading to potlucks, beginners who like foolproof recipes, and anyone who loves meals that taste even better the next day.

I still remember the summer evening when extra guests showed up for a backyard cookout.

Burgers were limited, but this pasta salad saved the day—stretching the meal effortlessly, and somehow everyone went back for seconds of the “side.”

It’s ideal for cookouts, office parties, family reunions, church gatherings, or those nights when you need something you can prep ahead for easy lunches all week.

Ingredients

• 2 pounds rotini pasta, dried — choose a short shape with ridges so dressing clings
• 1 tablespoon salt, for pasta water — seasons the pasta from within
• 1 cup cherry tomatoes, halved — use firm, sweet tomatoes for best texture
• 1 cup cucumber, diced — seed if very watery to keep salad crisp
• 1 cup red bell pepper, diced — adds sweetness and bright color
• 1 cup yellow bell pepper, diced — balances flavor and boosts visual appeal
• 1 cup red onion, finely diced — rinse briefly if you prefer milder bite
• 1 1/2 cups black olives, sliced — choose good-quality, pitted olives
• 2 cups mozzarella cheese, cubed — low-moisture holds shape better than fresh
• 1 cup salami, diced (optional) — pick a flavorful, cured variety
• 1/2 cup fresh parsley, chopped — flat-leaf gives better flavor than curly
• 1/2 cup grated Parmesan cheese — finely grated coats pasta evenly
• 1 1/4 cups extra-virgin olive oil — use a mellow, good-quality oil
• 3/4 cup red wine vinegar — provides bright, classic Italian-style tang
• 2 tablespoons Dijon mustard — helps emulsify and deepen flavor
• 2 teaspoons dried oregano — classic herb for Italian-style dressing
• 1 teaspoon dried basil — reinforces the herby, Mediterranean profile
• 1 teaspoon garlic powder — distributes garlic flavor more evenly than fresh
• 1 teaspoon sugar — lightly balances the acidity of vinegar
• 1 1/2 teaspoons salt — adjust to taste after chilling
• 1 teaspoon black pepper, ground — freshly ground gives best aroma

Step-by-Step Method

Bring a large stock pot of water to a rolling boil. Stir in the tablespoon of salt so the pasta is seasoned from the inside out.

Add the rotini and cook until al dente, about 10–12 minutes or as the package directs. Stir occasionally to prevent sticking and make certain the pasta cooks evenly.

Cool and Drain the Pasta

Pour the cooked pasta into a large colander. Rinse thoroughly under cold running water to stop the cooking and cool the pasta completely.

Shake and drain very well so there’s no excess water that could dilute the dressing.

Transfer the cooled pasta to a large mixing bowl and spread it out slightly to help it dry.

Whisk the Dressing

In a medium bowl, combine olive oil, red wine vinegar, Dijon mustard, dried oregano, dried basil, garlic powder, sugar, salt, and black pepper. Whisk vigorously until the mixture is emulsified and slightly thickened.

Taste and adjust seasoning if needed. Set aside while you prepare the vegetables and cheese so flavors begin to meld.

Prep and Add the Mix-Ins

Dice the cucumber, bell peppers, red onion, mozzarella, and salami if using. Halve the cherry tomatoes and slice the olives. Chop the fresh parsley.

Add all these prepared ingredients to the bowl with the cooled pasta. Gently toss to distribute everything evenly, ensuring a good mix of colors and textures throughout.

Dress and Toss the Salad

Pour the prepared dressing over the pasta and vegetables. Use a wooden spoon or spatula to toss thoroughly until every piece is lightly coated.

Sprinkle in the grated Parmesan cheese and toss again to distribute it evenly. Check that the dressing reaches the bottom of the bowl and no dry pockets of pasta remain.

Chill and Adjust Before Serving

Cover the bowl tightly with plastic wrap or transfer to an airtight container. Refrigerate for at least 1 hour so the flavors blend and the pasta absorbs some dressing.

Before serving, toss again, then taste. Add extra salt and pepper if needed, and drizzle in a bit more olive oil if the salad seems dry.

Ingredient Swaps

• Use gluten-free rotini or another short gluten-free pasta to make the salad celiac-friendly; cook just to al dente so it doesn’t fall apart.
• Swap salami for grilled chicken, chickpeas, or white beans for a lighter or vegetarian option, and use dairy-free mozzarella and Parmesan-style shreds for a vegan version.
• Sub red wine vinegar with white wine or apple cider vinegar, and if olive oil is pricey, use half olive oil and half neutral oil (like canola or sunflower) to stretch the budget.

You Must Know

– Make-Ahead for best texture: For up to 24 hours in advance, keep cheeses and fresh parsley separate, refrigerated, and stir them in 30 minutes before serving, so the mozzarella stays bouncy and the herbs look bright green.

Serving Tips

• Serve in a large shallow platter so colorful veggies and cheeses are visible.
• Offer small bowls of extra Parmesan, olives, and red pepper flakes for topping.
• Pair with grilled chicken, burgers, or sausages for a complete casual cookout meal.
• Spoon into individual clear cups for easy grab-and-go party portions.
• Garnish just before serving with extra parsley and a drizzle of olive oil.

Storage & Make-Ahead

Pasta salad keeps in the fridge for 3–4 days in an airtight container.

It’s ideal to make it several hours or a day ahead so flavors meld.

Stir before serving and refresh with a bit of olive oil or extra dressing.

This salad doesn’t freeze well; the pasta and veggies turn mushy.

Reheating

Reheat small portions briefly in the microwave with a splash of water or broth.

For larger amounts, warm covered in a low oven or gently on the stovetop, stirring to avoid overheating.

Potluck and Picnic Favorite

When I carry this big bowl of pasta salad into a potluck or spread it out on a picnic blanket, it practically announces itself before I can set it down.

Colors pop—red and yellow peppers, inky olives, bright parsley—all tumbling over curly pasta. You can hear the little clink of mozzarella cubes as I give it a final toss.

I love it for gatherings because it doesn’t wilt, droop, or demand attention. It waits patiently on the buffet while people circle back for “just one more spoonful.”

Outside, it’s even better: cool pasta, crisp cucumbers, and tangy red wine vinaigrette taste especially invigorating under the sun, with paper plates balanced on laps and everyone reaching in from every direction.

Final Thoughts

Give this Pasta Salad for a Crowd a try the next time you’re hosting friends or heading to a potluck—it comes together easily and feeds everyone generously.

Don’t hesitate to tweak the mix-ins and dressing to suit your tastes and make it your own.

Frequently Asked Questions

Can I Make This Pasta Salad Gluten-Free, and Which Pasta Brands Work Best?

You can absolutely make it gluten‑free; I’d choose sturdy, short shapes from Barilla Gluten Free, Jovial, or Banza. Cook just to al dente, chill well, then let that tangy vinaigrette cling to every ridge.

How Can I Safely Adapt This Recipe for Guests With Dairy Allergies?

You can, absolutely. I’d skip mozzarella and Parmesan, use dairy‑free cheese or extra olives and herbs, and double‑check salami’s labels. I’d mix the dressing separately, confirm every ingredient, and serve theirs with spotless, dedicated utensils.

What’s the Best Way to Scale This Recipe for 50 or 100 People?

I scale it linearly: for 50, I triple everything; for 100, I make six batches. I’d mix in separate huge bowls, glistening coils of pasta and jeweled veggies, then combine gently so nothing gets crushed.

How Long Can the Salad Sit Out at Room Temperature During a Party?

It can sit out safely for about 2 hours. After that, I’d tuck it back into the fridge; creamy mozzarella and juicy veggies warm fast, and you don’t want that lush, garlicky dressing turning risky.

Can I Turn This Into a Full Meal With Added Protein or Grains?

Yes, you absolutely can. I’d fold in grilled chicken, garlicky shrimp, or chickpeas, then swirl through chewy farro or quinoa—suddenly each bite feels hearty, textured, and satisfying enough to be dinner on its own.
