Ingredients for Pasta Salad Recipe for 100 People

Feeding a hundred starts with quality pasta and vibrant vegetables for this crowd-pleasing dish.

The pasta is the foundation—Barilla or De Cecco hold up best to large batches and won’t turn mushy. For the vegetables, Costco or Sam’s Club offer bulk produce at reasonable prices. Look for firm, unblemished peppers and cucumbers. The feta should be Greek-style (like Athens or President brands) for authentic flavor. Avoid pre-crumbled—it dries out faster.

Out of Kalamata olives? Green olives work at a one-to-one ratio. No fresh herbs? Use dried at one-third the amount, but add them to the dressing, not the salad. Red wine vinegar can be swapped with apple cider vinegar for a milder tang. The Dijon is flexible—yellow mustard plus a pinch of turmeric mimics the color and tang well enough.

This salad holds beautifully for 24-48 hours in the fridge, making it perfect for prep ahead. Store in large, shallow containers to avoid crushing the pasta. Dressing can be made 2 days in advance and kept separate until serving. Leftovers (if any) keep for 3-4 days.

Step-by-Step Instructions for Pasta Salad for 100 People

This method ensures perfect texture and flavor distribution for a large crowd.

Step 1: Cook and Cool the Penne Pasta

Bring a very large stockpot of generously salted water to a rolling boil. Add the 12.5 lb penne pasta and cook until al dente according to package directions, typically 10-12 minutes. Stir occasionally to prevent sticking.

Drain immediately and spread the pasta on large baking sheets. Drizzle lightly with some of the 5 cups extra-virgin olive oil and toss to prevent clumping. Let cool completely at room temperature—this prevents the pasta from absorbing too much dressing later.

Step 2: Prepare and Combine the Vegetables

In a very large container or clean food-safe bucket, combine the 10 lb halved cherry tomatoes, 15 whole diced english cucumbers, 20 whole diced red bell peppers, 10 whole thinly sliced red onions, and 5 lb pitted and halved kalamata olives.

Gently fold in the 7.5 lb crumbled feta cheese, being careful not to break it down too much. The feta should remain in visible crumbles for texture contrast. Sprinkle with 0.75 cup salt and 0.5 cup black pepper and toss lightly.

Step 3: Whisk Together the Dressing

In a large bowl, whisk together the remaining extra-virgin olive oil, 2.5 cups red wine vinegar, 1 cup dijon mustard, minced 20 cloves garlic cloves, and 0.5 cup dried oregano until fully emulsified.

The dressing should be thick enough to coat the back of a spoon. If it separates, continue whisking until smooth. This quantity ensures every component is well coated without making the salad soggy.

Step 4: Assemble and Chill the Salad

Add the cooled penne pasta to the vegetable mixture. Pour the dressing over and gently fold everything together until evenly distributed. You may need to work in batches if your container isn’t large enough.

Stir in the 2 cups chopped fresh parsley and 2 cups chopped fresh basil at the end to preserve their vibrant color and fresh flavor. Cover and refrigerate for at least 4 hours (overnight is ideal) to allow flavors to meld.

Before serving, give the salad a final gentle toss and adjust seasoning if needed. The pasta should be tender with a slight bite, and the vegetables should retain some crispness.
