Ingredients
For the Pasta Salad
- 1 pound spaghetti
- 2 cups cherry tomatoes, halved
- 2 cups cucumber, diced
- 1½ cups small broccoli florets
- 1 cup black olives, sliced
- 1/2 large red onion, diced
- 1 green bell pepper, diced, optional
- 1 red bell pepper, diced, optional
- 1/2 cup grated Parmesan cheese
- 2 tablespoons fresh parsley, chopped
- 1 tablespoon fresh basil, optional
For the Italian Dressing
- 3/4 cup extra-virgin olive oil
- 1/3 cup red wine vinegar
- 2 tablespoons fresh lemon juice
- 1 tablespoon Dijon mustard
- 1 teaspoon honey or sugar
- 2 garlic cloves, finely minced
- 1 teaspoon dried oregano
- 1 teaspoon dried basil

- 1/2 teaspoon onion powder
- 1/2 teaspoon black pepper
- 3/4 teaspoon salt, or to taste
- 2 tablespoons grated Parmesan, optional
Best Pasta to Use
Spaghetti is what gives this salad its distinctive appearance.
The long noodles become coated with dressing and weave around the vegetables, making the salad feel different from ordinary rotini or penne pasta salad.
Regular spaghetti works perfectly.
Thin spaghetti can also be used.
Angel hair is usually a little too delicate and may become overly soft after chilling.
If you prefer shorter pieces, break the spaghetti into thirds before boiling.
That makes the salad easier to scoop and serve at parties.
How to Cook Spaghetti for Pasta Salad
The most important rule is to avoid overcooking the pasta.
Cook the spaghetti until al dente.
You want it tender but still firm enough to hold its shape after chilling.
Pasta that is too soft when hot becomes even softer after absorbing dressing.
Use generously salted boiling water.
Once cooked, drain the spaghetti immediately.
For cold pasta salad, you can rinse it briefly under cool water to stop the cooking process and remove excessive surface starch.
Drain very thoroughly afterward.
Water remaining on the pasta can dilute the dressing.
Why Cherry Tomatoes Work So Well
Cherry or grape tomatoes are ideal because they stay relatively firm after being cut.
They also provide little bursts of sweetness throughout the salad.
Cut them in halves.
Very large cherry tomatoes can be quartered.
Avoid using extremely soft tomatoes because they can release too much liquid and make the bottom of the salad watery.
Best Cucumbers for Pasta Salad
English cucumbers are an excellent choice because they have thin skin and relatively few seeds.
Persian cucumbers also work beautifully.
If using a standard garden cucumber, you may want to peel some or all of the skin and remove the watery center seeds.
Dice the cucumber into bite-size pieces.
Keeping the pieces fairly small helps distribute them throughout the spaghetti.
Preparing the Broccoli
The broccoli in this salad should remain crisp.
Cut it into very small florets.
You can use it raw if you enjoy a crunchy texture.
For slightly more tender broccoli, blanch it.
Drop the florets into boiling water for approximately 30–60 seconds.
Immediately transfer them to ice water.
Drain and dry completely before adding to the salad.
This keeps the broccoli bright green while slightly softening its texture.
Why Black Olives Are Important
Black olives provide a salty, savory contrast to the fresh vegetables.
Their soft texture also works well with chilled pasta.
Use sliced black olives for the easiest preparation.
Kalamata olives can be substituted if you want a stronger Mediterranean flavor.
Because olives and Parmesan both contain salt, taste the salad before adding additional seasoning.
How to Make the Italian Dressing
Step 1: Add the Vinegar
Pour red wine vinegar into a jar or mixing bowl.
Add fresh lemon juice.
The combination provides acidity without making the dressing taste too sharp.
Step 2: Add Dijon Mustard
Add Dijon mustard.
Mustard helps emulsify the oil and vinegar so the dressing stays combined longer.
Step 3: Add Garlic
Stir in freshly minced garlic.
For a milder garlic flavor, use garlic powder only.
Step 4: Add Herbs
Add oregano, basil, Italian seasoning, onion powder, salt, and black pepper.
Step 5: Add Olive Oil
Slowly pour in the olive oil while whisking.
If using a jar, simply close the lid tightly and shake vigorously.
Step 6: Taste
Taste the dressing.
If it is too sharp, add a small amount of honey or sugar.
If it tastes flat, add another splash of vinegar or lemon juice.
Step-by-Step Instructions
Step 1: Cook the Spaghetti
Bring a large pot of salted water to a boil.
Add the spaghetti.
Cook until al dente according to package instructions.
Drain immediately.
Rinse briefly under cool water and drain extremely well.
Step 2: Cut the Vegetables
While the pasta cooks, prepare the vegetables.
Halve the tomatoes.
Dice the cucumber.
Chop the red onion.
Slice the olives.
Cut broccoli into small florets.
Dice bell peppers if using.
Step 3: Prepare the Dressing
Combine olive oil, red wine vinegar, lemon juice, Dijon mustard, garlic, herbs, salt, pepper, and a touch of honey.
Whisk or shake until emulsified.
Step 4: Add the Pasta to a Large Bowl
Place the cooled spaghetti in your largest mixing bowl.
If serving a large crowd, you can use a large food-safe tray or container.
Step 5: Add the Vegetables
Add the tomatoes, cucumber, broccoli, red onion, olives, and optional peppers.
Distribute everything evenly.
Step 6: Add Parmesan
Sprinkle grated Parmesan over the salad.
Parmesan adds savory flavor and helps the dressing cling to the pasta.
Step 7: Pour Over the Dressing
Start with approximately three-quarters of the dressing.
Toss thoroughly.
Long spaghetti requires a little patience to mix evenly.
Use two large serving spoons or clean tongs.
Step 8: Chill
Cover the salad.
Refrigerate for at least 1 hour.
Two to four hours gives even better flavor.
Step 9: Toss Again
Before serving, toss the salad once more.
The pasta will absorb part of the dressing during chilling.
Add the remaining dressing if the salad looks dry.
Step 10: Garnish
Finish with:
- Parmesan
- Fresh parsley
- Basil
- Black pepper
Serve chilled or slightly cool.
How to Keep Pasta Salad from Becoming Dry
Pasta absorbs dressing as it sits.
That is why a pasta salad that looks perfectly dressed when freshly mixed may seem dry after several hours.
The easiest solution is to reserve some dressing.
Add about 75% initially.
Keep the remaining dressing refrigerated.
Before serving, toss the pasta and add more as needed.
Another trick is to make the initial dressing slightly more generous than you think necessary.
How to Keep the Vegetables Crisp
Dry the vegetables thoroughly after washing.
Excess water dilutes dressing and softens the salad.
Do not cut cucumbers too far ahead unless necessary.
If preparing the salad the night before, use firm cucumbers, peppers, broccoli, olives, and onions.
Tomatoes can be added several hours before serving, but very ripe tomatoes may be better added closer to serving time.
Pro Tips for the Best Spaghetti Pasta Salad
Cook spaghetti only until al dente.
Drain the pasta very well.
Cut vegetables into small bite-size pieces.
Use enough dressing so every noodle gets coated.
Reserve some dressing for serving.
Chill the salad before eating.
Taste again after refrigeration because cold foods often need slightly more seasoning.
Add fresh herbs shortly before serving.
Do not overload the salad with too many wet ingredients.
Italian Dressing Shortcut
If you want an even faster version, use a good-quality bottled Italian dressing.
You will need approximately 1½ cups for one pound of pasta, depending on how heavily dressed you like your salad.
Start with one cup.
Add more after chilling.
You can improve bottled dressing by mixing in:
- Fresh lemon juice
- Parmesan
- Fresh garlic
- Black pepper
- Dried oregano
This creates a more homemade flavor without making dressing from scratch.
Classic Italian Spaghetti Salad Variation
For an old-fashioned potluck-style version, add:
- 1 packet dry Italian dressing seasoning
- 1 cup bottled Italian dressing
- Parmesan cheese
- Cherry tomatoes
- Cucumbers
- Black olives
- Red onion
This version has a bold, tangy flavor and is especially popular for large gatherings.
Mediterranean Spaghetti Salad
Turn the recipe into a Mediterranean-style pasta salad by adding:
- Kalamata olives
- Feta cheese
- Cucumbers
- Tomatoes
- Red onion
- Fresh parsley
- Roasted red peppers
Use an olive oil, lemon, garlic, and oregano dressing.
This variation is excellent served with grilled chicken or fish.
Greek Spaghetti Pasta Salad
For a Greek-inspired version, use:
- Feta cheese
- Kalamata olives
- Tomatoes
- Cucumber
- Red onion
- Green bell pepper
- Oregano
Add plenty of lemon juice to the dressing.
You can also add chickpeas for extra protein.
Chicken Spaghetti Pasta Salad
Turn this side dish into a complete lunch by adding cooked chicken.
Use approximately:
- 2–3 cups chopped grilled chicken
- Rotisserie chicken
- Roasted chicken breast
Add the chicken after the pasta has cooled.
Chicken works especially well with the Italian dressing and fresh vegetables.
Pepperoni Spaghetti Salad
For an Italian deli-inspired variation, add:
- Sliced pepperoni
- Cubed mozzarella
- Cherry tomatoes
- Black olives
- Peppers
- Parmesan
This version is particularly good for parties because it is more filling.
Salami can also be used instead of pepperoni.
Mozzarella Spaghetti Salad
Fresh mozzarella makes this salad feel more substantial.
Use small mozzarella pearls or cut a larger ball into cubes.
Add them after the pasta has cooled completely.
Fresh mozzarella, tomatoes, basil, and Italian dressing create a Caprese-inspired flavor.
Broccoli Spaghetti Salad
Increase the broccoli to approximately 3 cups.
Add shredded carrots and sunflower seeds if desired.
This gives the pasta salad even more crunch.
Parmesan and Italian dressing work particularly well with broccoli.
Spicy Italian Pasta Salad
For extra heat, add:
- Pepperoncini
- Red pepper flakes
- Jalapeños
- Spicy salami
A small spoonful of pepperoncini brine can also be added to the dressing.
Start conservatively because the brine can be salty.
What to Serve with Spaghetti Pasta Salad
This is a versatile side dish that pairs with many main courses.
It is particularly good with:
- Grilled chicken
- Hamburgers
- Hot dogs
- BBQ chicken
- Grilled steak
- Pulled pork
- Grilled shrimp
- Baked chicken
- Sandwiches
- Roast beef
For a vegetarian meal, serve it alongside grilled vegetables, beans, or chickpeas.
Perfect for BBQs and Cookouts
Cold pasta salad is one of the easiest sides to prepare for a barbecue.
Make it early in the morning.
Refrigerate.
Toss with additional dressing shortly before guests arrive.
It pairs with nearly everything served from the grill.
For a large party, double the recipe and use a large foil serving tray similar to the one shown in the image.
Perfect for Potlucks
This recipe travels well.
Keep it refrigerated until you leave.
Transport it in a covered container.
For outdoor gatherings, keep cold foods properly chilled rather than letting them sit in warm conditions for extended periods.
Bring a small container of extra dressing.
Give the salad one final toss before putting it on the serving table.
Make-Ahead Instructions
This salad can be prepared up to one day ahead.
Cook the spaghetti and prepare the vegetables.
Toss with approximately three-quarters of the dressing.
Cover tightly and refrigerate.
Before serving, toss thoroughly and add additional dressing if necessary.
Fresh basil and parsley are best added near serving time.
Storage
Store leftover pasta salad in an airtight container in the refrigerator.
For best quality, use within 3–4 days.
The vegetables will gradually soften.
The pasta will also continue absorbing dressing.
Add a splash of Italian dressing before serving leftovers.
Can You Freeze Pasta Salad?
Freezing is not recommended.
Cooked pasta can technically be frozen, but tomatoes, cucumbers, and fresh vegetables often become watery and soft after thawing.
The dressing may also separate.
This salad is much better prepared fresh and refrigerated.
Common Mistakes and How to Avoid Them
Overcooking the Pasta
Al dente pasta holds its shape better after chilling.
Not Draining Well
Excess water weakens the dressing.
Using Too Little Dressing
Spaghetti absorbs dressing during storage.
Adding All the Dressing Immediately
Reserve some for refreshing the salad later.
Cutting Vegetables Too Large
Smaller pieces distribute more evenly throughout the spaghetti.
Forgetting to Chill
Resting allows the flavors to blend.
Serving Straight from the Refrigerator Without Retasting
Cold food can taste less seasoned.
Taste and adjust before serving.
