Ingredients for Pasta Salad Recipe for 50 People
Pantry raid plus a quick produce run. Feeds fifty with zero stress.
| Ingredient | Amount | Notes |
|---|---|---|
| Rotini Pasta 🍝 | 5 lb | Tri-color for visual appeal |
| Cherry Tomatoes 🍅 | 10 cups | Halved for even distribution |
| English Cucumber 🥒 | 8 whole | Diced with skin on |
| Red Bell Pepper 🌶️ | 6 whole | Diced into 1/2-inch pieces |
| Red Onion 🧅 | 4 whole | Thinly sliced for bite |
| Kalamata Olives 🫒 | 3 cups | Pitted and halved |
| Feta Cheese 🧀 | 3 lb | Crumbled for even coverage |
| Extra-Virgin Olive Oil 🫒 | 3 cups | For dressing base |
| Red Wine Vinegar 💧 | 2 cups | Balances the richness |
| Dijon Mustard 🟡 | ½ cup | Smooth, not whole grain |
| Dried Oregano 🌿 | ¼ cup | For Mediterranean flair |
| Garlic Powder 🧄 | 3 tbsp | Uniform flavor distribution |
| Salt 🧂 | ½ cup | Kosher or sea salt preferred |
| Black Pepper 🌶️ | ¼ cup | Freshly ground for best flavor |
| Fresh Parsley 🌿 | 2 cups | Chopped for garnish |
The pasta is the foundation—Barilla or De Cecco rotini holds up best to dressing and won’t turn mushy. Costco’s bulk rotini is a budget-friendly option for this quantity. For the veggies, hit the farmers market if it’s in season (better flavor, often cheaper in bulk). The feta? Athens or President brands crumble nicely and aren’t overly salty. Don’t skimp on the olives—Mezzetta Kalamatas are my go-to.
No rotini? Penne or fusilli work just as well—just avoid long pastas like spaghetti. Swap the feta for goat cheese or cubed cheddar if that’s what you’ve got. Out of red wine vinegar? Apple cider vinegar at the same amount keeps the tang. The cucumber can be swapped for celery (same crunch, different flavor). Fresh herbs? Dried basil at one-third the amount works in a pinch.
This keeps 3-4 days in the fridge—perfect for making ahead. Store the dressing separately if prepping a day in advance. Leftovers? Pack into individual containers for easy grab-and-go lunches. Freezing isn’t ideal (the veggies get soggy), but it’ll hold for 1 month if absolutely necessary.

Step-by-Step Instructions for Pasta Salad For 50 People
Here’s the method. Simple, efficient, and perfectly scaled for a crowd.
Step 1: Cook and Cool the Rotini Pasta
Bring a very large stockpot of water to a rolling boil and salt it generously with ½ cup salt. Add all 5 lb rotini pasta and cook according to package directions until al dente—about 1 minute less than the recommended time.
Drain immediately in a colander and rinse under cold water to stop the cooking process. This prevents the pasta from turning mushy when dressed. Spread it out on large baking sheets in a single layer to cool completely. I always let it sit for 15-20 minutes, stirring occasionally to release steam.
Step 2: Prepare All Vegetables and Cheese
While the pasta cools, prep all your vegetables. Halve the 10 cups cherry tomatoes, dice the 8 whole English cucumber with skin on, and cut the 6 whole red bell pepper into ½-inch pieces. Thinly slice the 4 whole red onion for a nice bite.
Pit and halve the 3 cups Kalamata olives, and crumble the 3 lb feta cheese into small, even pieces. This uniform sizing ensures every bite has a balanced mix of flavors and textures. Chop the 2 cups fresh parsley just before assembling to maintain its bright color.
Step 3: Whisk Together the Dressing
In a large bowl, combine the 3 cups extra-virgin olive oil, 2 cups red wine vinegar, ½ cup Dijon mustard, ¼ cup dried oregano, 3 tbsp garlic powder, and ¼ cup black pepper. Whisk vigorously until the dressing emulsifies and thickens slightly.
Taste and adjust seasoning if needed, though the ½ cup salt from the pasta water and the salty feta should provide enough flavor. The dressing should be tangy with a smooth, creamy texture from the mustard. Let it sit for 5 minutes to allow the flavors to meld.
Step 4: Combine Everything and Chill
In an extra-large serving bowl or clean food-service container, combine the cooled rotini pasta, all the prepped vegetables, and the crumbled feta cheese. Pour the dressing over and fold everything together gently but thoroughly—you want every piece coated without breaking apart the pasta or vegetables.
Cover the bowl tightly with plastic wrap and refrigerate for at least 2 hours (overnight is even better). This chilling time lets the flavors develop and the pasta absorb the dressing. Stir once halfway through chilling to redistribute the dressing evenly.
Step 5: Garnish and Serve
Just before serving, give the pasta salad a final stir and taste for seasoning. Sprinkle the chopped 2 cups fresh parsley over the top for a pop of color and freshness. The parsley adds a bright finish that balances the rich, tangy flavors.
Serve chilled in the bowl or transfer to a large serving platter. This dish holds up well at room temperature for a party, but for best results, keep it on ice if serving outdoors. The colors should be vibrant, and every bite should offer a mix of textures and flavors.
Pro Tips For Making Pasta Salad Recipe For 50 People
- Salt the Pasta Water: Use at least 1/4 cup kosher salt in the boiling water for 5 pounds of rotini—I learned this the hard way after serving bland pasta salad to 50 people once.
- Seed the Cucumber: English cucumbers have fewer seeds, but for 50 servings, take the extra 10 minutes to halve and scoop out any excess seeds to prevent a watery salad.
- Shock the Pasta: Drain the rotini, then immediately rinse under cold water to stop cooking—this keeps it al dente even after dressing sits for hours.
- Slice Onions Thin: Soak the red onion in ice water for 15 minutes after slicing paper-thin; it softens the bite and makes them crisp enough to hold up in a big batch.
