Summer Spaghetti Pasta Salad
Spaghetti Pasta Salad is a fresh, colorful side dish tossed in a zesty homemade Italian-style dressing with crisp vegetables and mozzarella cheese. It’s an easy make-ahead recipe that’s perfect for potlucks, BBQs, picnics, and summer gatherings.

Instead of using bottled dressing, this recipe combines olive oil, red wine vinegar, herbs, and Dijon mustard for a bright, balanced flavor that complements the vegetables without overpowering them.
I always rinse the spaghetti under cold water after cooking to stop the cooking process and cool it quickly without becoming mushy. Letting the salad chill for at least an hour before serving also gives the dressing time to blend with the vegetables and pasta.

How to Make Spaghetti Pasta Salad
This is a quick overview of the step-by-step instructions for making this recipe. You can find the complete list of instructions in the printable recipe card at the bottom of this post.

- Cook the spaghetti according to the package directions until al dente. Drain the pasta and rinse under cold water until completely cooled. Add to a large bowl.

- In a large mixing bowl, combine the cooled spaghetti, cherry tomatoes, cucumber, red bell pepper, red onion, black olives, and mozzarella.

- In a small bowl or mason jar, whisk together the olive oil, red wine vinegar, Dijon mustard, oregano, basil, garlic powder, salt, black pepper, and sugar if using.

- Pour the dressing over the pasta mixture.

- Cover and refrigerate for at least 1 hour to allow the flavors to blend. Toss once more before serving and garnish with fresh parsley if desired.
Substitutions and Additions
- Protein Pasta. Use Barilla brand protein pasta to keep this dish vegetarian, but with extra protein.
- Add protein. Grilled chicken, pepperoni, or salami make this a complete meal.
- Swap the cheese. Feta or cubed provolone are delicious alternatives.
- Mix in more vegetables. Broccoli, pepperoncini, artichokes, or spinach all work well.
Sandra’s Pro Tips
- Cook the pasta just until al dente. Slightly firm pasta holds its texture better after chilling.
- Cool the pasta completely. Rinsing with cold water stops the cooking and keeps the pasta from sticking together.
- Don’t skip the chill time. Refrigerating the salad for at least an hour allows the dressing to soak into the pasta.
- Toss before serving. A quick toss redistributes the dressing and fresh ingredients.

Notes
How To Store
Refrigerator: Store leftovers in an airtight container for up to 4 days. Freezer: Freezing isn’t recommended because the vegetables and dressing lose their fresh texture after thawing. How to Serve: Serve chilled. If the pasta has absorbed much of the dressing after storing, toss with a small drizzle of olive oil or a splash of red wine vinegar before serving to freshen it up.Nutrition
