For the Salad Dressing:

For the Pasta Salad:


  • In a small bowl with a whisk, or in a jar with a tight-fitting lid, combine olive oil, red wine vinegar, Parmesan cheese, sesame seeds, oregano, poppy seeds, garlic, paprika, celery seed, and salt. Mix well and allow flavors to blend while preparing the salad.
  • Bring 4 quarts water and 1 tablespoon salt to boil. Add spaghetti and cook according to package directions, about 9 minutes. Drain well and rinse in cold water.
  • In a large bowl add zucchini, tomatoes, cucumber, bell peppers, onion, and black olives. Add rinsed pasta and drizzle with salad dressing to taste (you don't have to use it all). Toss to combine, cover, and chill at least 2 hours or overnight.



  1. Thin spaghetti: Yes, I know Italian chefs will scoff at me recommending that you break the noodles into thirds. I strongly suggest that you follow suit, however; this allows the pasta to not only cook faster and fit easier into your pot, but also makes it easier to eat.
  2. Grape tomatoes: Cherry tomatoes or chopped Roma, classic, or heirloom tomatoes can also pinch hit.
  3. Canned black olives: I know these are polarizing, so feel free to omit. But I adore the briny element they add to the pasta salad.
  4. Yield: This California Pasta Salad recipe makes a whopping 16 1-cup servings. Talk about perfect for parties, potlucks, or picnics! Feel free to halve the recipe if you're sharing it with a smaller crew.
  5. Storage: Transfer extra pasta salad to an airtight container in the refrigerator up to 4 days
  6. Make ahead: California Pasta Salad can be assembled up to 3 days in advance. Store in an airtight container in the refrigerator until ready to serve. Toss gently before serving.
