What You Need to Make This California Veggie Spaghetti Salad
Thin spaghetti (about 1 pound) – The base of the salad; breaking it into smaller pieces makes it easier to eat and helps the dressing coat every strand.
Cherry tomatoes – Juicy, sweet pops of flavor that balance the tangy dressing and add that classic California color.
Cucumber – Brings cool crunch and freshness; it lightens up the pasta and keeps every bite crisp.
Green bell pepper – Adds mild, grassy flavor and extra crunch; it pairs nicely with the zesty Italian-style dressing.
Red bell pepper – Slightly sweeter than green pepper and adds a bright, vibrant contrast in both taste and color.
Red onion – Finely chopped for sharp, savory notes that keep the salad from tasting flat; a little goes a long way.
Sliced black olives – Briny, salty bites that give the salad a Mediterranean twist and extra depth.
Italian dressing (one 16-ounce bottle) – The flavor backbone; use a tangy, oil-and-vinegar style dressing to soak into the pasta and veggies.
Grated Parmesan cheese – Adds savory richness and a subtle creamy texture to the dressing as it clings to the noodles.
Sesame seeds – Tiny but mighty; they bring a nutty flavor and a bit of texture to each forkful.
Paprika – Offers mild warmth and a hint of smokiness to round out the dressing.
Garlic powder – Infuses gentle garlic flavor throughout the salad without overpowering the fresh vegetables.
Celery seed – A classic pasta-salad seasoning that gives that nostalgic deli-style taste.
Salt and black pepper – Essential for balancing flavors; taste after chilling and adjust to make everything pop.

Step-by-Step California Veggie Spaghetti Salad
STEP 1: Cook the spaghetti in a large pot of well-salted boiling water until it’s just al dente. You want the noodles tender but still firm so they hold up after chilling.
STEP 2: Drain the pasta and immediately rinse it under cold water to stop the cooking. Shake off as much water as you can and let it sit in the colander to dry slightly.
STEP 3: While the pasta cools, chop the cucumber and both bell peppers into small bite-size pieces. Halve the cherry tomatoes, finely dice the red onion, and drain the sliced olives.
STEP 4: Add the cooled spaghetti to a large serving bowl. Toss in the tomatoes, cucumber, peppers, red onion, and olives, gently mixing everything so the veggies are evenly dispersed.
STEP 5: In a separate bowl or jar, whisk together the Italian dressing, grated Parmesan, sesame seeds, paprika, garlic powder, celery seed, and a pinch of salt and pepper until well blended.
STEP 6: Pour the dressing over the pasta and vegetables. Toss thoroughly, making sure every strand and veggie piece gets coated. Cover the bowl and refrigerate for at least 2 hours, or up to overnight, to let the flavors meld.
STEP 7: Before serving, give the salad a good stir, then taste and adjust the seasoning with a little extra salt, pepper, or Parmesan if needed. Serve chilled and enjoy.
Pro Tips for California Veggie Spaghetti Salad
- Toss the pasta with a small splash of dressing while it’s still slightly warm so it absorbs flavor instead of clumping.
- If the salad seems a little dry after chilling, simply stir in a bit more Italian dressing right before serving to refresh it.
- For extra color and crunch, you can sprinkle a few more sesame seeds and a light dusting of Parmesan over the top just before bringing it to the table.

Can I make this spaghetti salad the day before?
Yes, this salad is ideal for making ahead. Prepare it completely, chill overnight, then stir and refresh with a splash of dressing before serving to wake up the flavors.
How do I keep the pasta from sticking together?
Rinse the cooked spaghetti under cold water, drain it very well, then toss it with a little dressing before adding the vegetables. This lightly coats the strands and keeps them separate.
Can I add protein to make it a full meal?
Absolutely. Diced salami, grilled chicken, or chickpeas all work well. Fold them in after you mix the salad so they stay intact and don’t break up the vegetables.
Is there a way to tone down the onion flavor?
If you prefer a milder onion bite, soak the chopped red onion in cold water for 5–10 minutes, then drain and pat dry before adding to the salad.
What to Serve with California Veggie Spaghetti Salad
This salad makes a perfect partner for anything off the grill—think grilled chicken, steak, or burgers. The bright, tangy flavors cut through rich, smoky meats beautifully.
It’s also great alongside simple sandwiches like turkey club, ham and cheese, or veggie wraps for a light but satisfying lunch or picnic spread.
For a buffet-style meal, pair it with other cold sides such as coleslaw, fruit salad, or a simple green salad to give your guests plenty of fresh options.

Keeping Leftovers Fresh
Store any leftover California Veggie Spaghetti Salad in an airtight container in the refrigerator. It usually tastes even better the next day as the flavors continue to blend.
For the best texture, enjoy within 3–4 days. If it thickens or seems a bit dry after sitting, stir in a spoonful or two of extra Italian dressing before serving again.
Because this is a chilled pasta salad, there’s no need to reheat it. Simply give it a toss, adjust the seasoning if needed, and serve straight from the fridge.
