What Makes It Special
This isn’t your average pasta salad. Here’s why it stands out:
Spaghetti soaks up every bit of the bold, tangy dressing.
Fresh vegetables like zucchini, cucumber, tomatoes, and peppers add crunch and color.
The dressing is more than just bottled Italian — it’s boosted with Parmesan, sesame seeds, paprika, garlic, and celery seed for an extra layer of flavor.
Black olives bring a briny, savory edge that balances the bright dressing.
And here’s the kicker: it tastes even better the next day.
Ingredients
For the salad:
400 to 500 grams of spaghetti (about 14 to 16 ounces)
1 ½ cups cherry tomatoes, halved
1 medium cucumber, diced
2 zucchini, diced
1 green bell pepper, diced
1 red bell pepper, diced
1 small red onion, finely diced
1 small can of sliced black olives, drained (about 3.8 ounces)
For the dressing:
1 bottle of Italian dressing (about 16 ounces)
½ cup grated Parmesan cheese
1 tablespoon sesame seeds
1 teaspoon paprika
½ teaspoon celery seeds
½ teaspoon garlic powder
How to Make California Spaghetti Salad
1. Cook the Pasta
Bring a large pot of salted water to a boil. Cook the spaghetti until just al dente.
Drain and rinse under cold water to stop the cooking and cool the noodles completely. Set aside.
Pro tip: Cut the spaghetti into shorter lengths before mixing — it makes tossing and serving easier.
2. Chop the Vegetables
While the pasta cools, wash and prepare your veggies:
Halve the cherry tomatoes. Dice the cucumber, zucchini, bell peppers, and red onion. Drain the olives. Keep everything bite-sized and fresh.
3. Make the Dressing
In a bowl, whisk together the Italian dressing, Parmesan, sesame seeds, paprika, celery seeds, and garlic powder. Stir until the dressing is well combined and the cheese is evenly mixed in.
4. Toss It All Together
In a large mixing or serving bowl, combine the cooled pasta, chopped vegetables, and olives. Pour the dressing over the top and toss until everything is evenly coated.
5. Chill and Let the Flavors Marry
Cover and refrigerate for at least 3 hours — or overnight if possible.
The chilling time allows the spaghetti to absorb the dressing and the flavors to blend beautifully.
Tips for the Best Results
Use fresh Parmesan for a richer, creamier dressing.
Let it chill — this salad is best after several hours or even the next day.
Add protein like grilled chicken, shrimp, or chickpeas to make it a complete meal.
Cut spaghetti shorter before mixing for easier serving and eating.
When to Serve It
This dish is endlessly versatile:
Potlucks & cookouts – It travels well and stays fresh without wilting.
Weekly meal prep – Store it in containers for easy lunches.
Family dinners – Serve it with grilled meats, sandwiches, or even pizza.
How to Store
Store leftovers in an airtight container in the refrigerator for up to 3 days. Stir before serving to redistribute the dressing.
Final Thoughts
California Spaghetti Salad is more than just a side dish — it’s a colorful, crowd-pleasing staple that’s easy to make, full of fresh ingredients, and bursting with bold flavor.
