This colorful California Spaghetti Salad has been my summer potluck signature for years. The vibrant mix of garden-fresh vegetables and perfectly cooked pasta creates a dish that disappears within minutes at every gathering. Cool, refreshing, and bursting with Mediterranean flavors, this pasta salad delivers a taste of California sunshine no matter where you serve it.
I first created this recipe for my daughter's graduation party when we needed something substantial yet refreshing for an outdoor summer celebration. The colorful presentation and delicious flavor made it an instant hit, and now it's requested at every family gathering from May through September.
Ingredients
- Spaghetti: Broken into smaller pieces makes this salad easier to serve and eat
- Cucumber: Adds refreshing crunch look for firm ones with minimal seeds
- Red and yellow bell peppers: Provide sweet flavor and vibrant color
- Cherry tomatoes: Contribute juicy bursts of flavor select ripe but firm ones
- Red onion: Delivers a sharp bite that balances the other flavors
- Black olives: Add briny Mediterranean notes
- Parmesan cheese: Provides a savory umami element
- Italian dressing: Creates a flavorful base for the homemade dressing
- Red wine vinegar: Adds brightness and acidity
- Dried herbs and seasonings: Infuse the dressing with classic Italian flavor
- Fresh basil: Brings a final aromatic touch
Step-by-Step Instructions
- Cook the Pasta to Perfection:
- Bring a large pot of water to a rolling boil and add a generous tablespoon of salt. Add broken spaghetti pieces and cook until just al dente about 8 to 10 minutes. Immediately rinse under cold water to stop the cooking process and drain thoroughly. The pasta should have a slight bite as it will continue to absorb dressing.
- Prepare the Fresh Vegetables:
- Dice the cucumber after removing the seeds to prevent excess moisture in the salad. Cut bell peppers into small uniform pieces for consistent flavor in each bite. Halve cherry tomatoes along their equator to release their juicy goodness. Finely chop red onion to distribute its flavor without overwhelming. Slice olives thinly to spread their briny flavor throughout the dish.
- Create the Flavorful Dressing:
- In a small bowl, combine Italian dressing with red wine vinegar for tanginess. Add garlic powder for depth without harsh raw garlic flavor. Sprinkle in Italian seasoning to enhance the Mediterranean profile. Whisk all dressing ingredients together until completely integrated into a smooth emulsion.
- Assemble the Salad:
- In your largest mixing bowl, combine cooled pasta with all prepared vegetables. The pasta should be completely cool to prevent wilting the fresh ingredients. Pour the dressing over the mixture gradually, tossing between additions to ensure even coating. Sprinkle with Parmesan cheese and toss gently to incorporate.
- Season and Chill:
- Taste the salad and adjust seasonings with salt and pepper. Remember that flavors will intensify as the salad chills. Cover the bowl tightly and refrigerate for at least one hour but preferably 3 to 4 hours to allow flavors to marry and develop.
- Finish and Serve:
- Just before serving, toss the salad once more to redistribute the dressing that may have settled. Garnish generously with freshly chopped basil for a pop of color and fresh herb flavor. Serve cold alongside your favorite summer dishes.

The broken spaghetti pieces are truly what make this salad special. I discovered this technique after attending a garden party where the hostess served a similar dish. The smaller pasta pieces allow you to get a perfect bite with vegetables and dressing in every forkful, unlike longer strands that can be challenging to eat in a social setting.
Make It Your Own
This California Spaghetti Salad welcomes many variations. Try adding diced avocado just before serving for creamy richness. Substitute feta cheese for Parmesan to give it a Greek twist. For protein, add diced salami, grilled chicken, or chickpeas to transform it into a complete meal. The recipe is forgiving and adaptable to what you have on hand or your personal preferences.
Storage Tips
For maximum freshness, store this pasta salad in an airtight container in the refrigerator for up to 3 days. The flavors actually improve after the first day as the pasta absorbs more of the dressing. If making significantly ahead of time, reserve some dressing to refresh the salad just before serving, as the pasta will continue to absorb liquid during storage.
Serving Suggestions
This versatile salad pairs beautifully with grilled proteins like chicken, fish, or steak. Serve it alongside burgers or sandwiches for a backyard barbecue. For a light lunch, enjoy it on its own with a slice of crusty bread. I love setting it out as part of a Mediterranean antipasto spread with hummus, olives, and fresh vegetables for casual entertaining.

This California Spaghetti Salad is sure to become a favorite at your summer gatherings, bringing vibrant flavors and a taste of sunshine to any table.
