Step-by-Step Instructions

- Cook the pasta: Bring a large pot of salted water to a boil. Add the spaghetti and cook until al dente according to package directions.
Drain well.
- Cool the pasta: Rinse the spaghetti briefly under cold water to stop the cooking and cool it down. Shake off excess water. Toss with a splash of olive oil to prevent sticking.
- Make the dressing: In a jar or bowl, whisk together olive oil, red wine vinegar, lemon juice, garlic, Dijon, honey, oregano, basil, red pepper flakes, salt, and pepper until emulsified.
- Prep the veggies: Halve the tomatoes, dice the cucumber and bell peppers, and thinly slice or finely dice the red onion.
Slice the olives.
- Toss it all together:-strong> In a large bowl, combine the cooled spaghetti, tomatoes, cucumber, peppers, onion, olives, and parsley. Pour over most of the dressing and toss until coated.
- Add cheese and adjust: Sprinkle in the Parmesan and toss again. Taste and add more dressing, salt, or pepper as needed.
- Chill: Cover and refrigerate for at least 1 hour, preferably 2–4 hours.
The flavors meld and the pasta absorbs the dressing.
- Serve: Before serving, toss again. If it seems dry, splash in a bit more dressing or a drizzle of olive oil and a squeeze of lemon.
Storage Instructions
- Refrigerate: Store in an airtight container for 3–4 days. The flavor deepens over time.
- Refresh before serving: Stir, then add a small splash of oil and vinegar or lemon if it’s absorbed the dressing.
- Avoid freezing: The vegetables lose their crisp texture when thawed.

No last-minute panic.

Common Mistakes to Avoid
- Overcooking the pasta: Soft spaghetti will break and turn mushy. Aim for firm al dente.
- Skipping the rinse: For cold pasta salads, a quick rinse stops cooking and prevents clumping.
- Under-seasoning: Cold foods need a little extra seasoning. Taste and adjust salt and acid after chilling.
- Soggy veggies: Use firm cucumbers and crisp peppers.
Seed watery cucumbers if needed.
- Adding all the dressing at once: Hold back a few tablespoons to refresh the salad before serving.
Alternatives
- Protein boost: Add diced salami, mini pepperoni, grilled chicken, or chickpeas.
- Cheese swap: Try feta, fresh mozzarella pearls, or pecorino instead of Parmesan.
- Veggie variations: Artichoke hearts, roasted red peppers, zucchini ribbons, or blanched broccoli.
- Herb twist: Fresh basil, dill, or chives brighten the salad. Add just before serving.
- Gluten-free: Use gluten-free spaghetti and rinse gently to keep it from breaking.
- Dressing shortcut: A good-quality bottled Italian dressing works in a pinch; add a squeeze of lemon for freshness.
FAQ
Can I make this a day ahead?
Yes. In fact, it’s better when made a few hours in advance.
Keep a little extra dressing to stir in just before serving.
What pasta shape works best besides spaghetti?
Rotini, bow ties, or penne all work well. Spaghetti is classic for this recipe’s texture, but short shapes hold chunky veggies nicely.
How do I keep the pasta from sticking?
Rinse with cold water after cooking, drain well, and toss with a small splash of olive oil while it cools. This keeps strands separate.
Is there a way to make it lighter?
Use less oil in the dressing and add extra lemon juice or vinegar.
You can also skip the cheese or use a smaller amount of a sharp cheese for more flavor per bite.
How spicy is it?
It’s mild by default. Add crushed red pepper to taste if you want a little heat.
Can I serve this warm?
This is designed as a cold salad. If you want it warm, skip rinsing the pasta and toss with the dressing off heat, but the veggies will soften slightly.
What if I don’t like olives?
Leave them out or swap in marinated artichokes or capers for briny flavor.
The salad still tastes great without olives.
How do I prevent the onion from overpowering the salad?
Soak sliced red onion in cold water for 10 minutes, then drain. It mellows the bite without losing flavor.
Can I use bottled Italian dressing?
Yes. Choose a tangy, good-quality brand.
Brighten it with a squeeze of lemon and a pinch of dried oregano for a fresher taste.
What should I serve it with?
It pairs with grilled chicken, burgers, sausages, or fish. It’s also perfect on its own for lunch with a side of fruit.
In Conclusion
Classic California spaghetti salad is easy, colorful, and reliably delicious. With a crisp mix of veggies and a zesty dressing, it’s the kind of dish people scoop onto their plates without hesitation.
