Quick Recipe Summary

Ingredients

Pasta

  • 1 lb spaghetti, broken into halves or thirds

Vegetables

  • 1½ cups cherry tomatoes, halved
  • 1 cucumber, diced
  • 2 zucchini, diced
  • 1 red bell pepper, diced
  • 1 green bell pepper, diced
  • 1 red onion, diced
  • 1 can black olives, sliced or diced

Dressing

  • 1 bottle Italian dressing (about 16 oz)
  • ½ cup grated Parmesan cheese
  • 1 tbsp sesame seeds
  • 1 tsp paprika
  • ½ tsp celery seed
  • ¼ tsp garlic powder

Instructions

  1. Cook spaghetti in salted water until al dente.
  2. Drain and rinse under cold water.
  3. Combine cooled pasta with all chopped vegetables in a large bowl.
  4. Mix Italian dressing, Parmesan, sesame seeds, paprika, celery seed, and garlic powder in a separate bowl.
  5. Pour dressing over the salad and toss thoroughly.
  6. Refrigerate for at least 2–3 hours before serving.

Why It Works

  • Uses spaghetti instead of traditional pasta shapes, giving it a distinctive texture.
  • Loaded with crunchy vegetables for freshness.
  • The dressing becomes more flavorful as it sits, making it ideal for preparing ahead of time.
  • Easy to customize with additional vegetables, cheese, or protein.

Useful Tips

  • Salt the pasta water generously.
  • Rinse pasta well after cooking to stop the cooking process and reduce sticking.
  • Cut vegetables into similar-sized pieces for a balanced bite.
  • If making a day ahead, reserve a little dressing to refresh the salad before serving.

Optional Add-Ins

  • Grilled chicken
  • Salami or pepperoni
  • Feta cheese
  • Mozzarella pearls
  • Crushed red pepper flakes for heat

Storage

  • Refrigerate in an airtight container for 4–5 days.
  • Freezing is not recommended because the vegetables become watery and soft when thawed.

A Small Note

The recipe's use of raw zucchini is somewhat unusual compared with many pasta salads, but it works well because the zucchini stays crisp and absorbs the dressing during chilling. If you prefer a softer texture, you can lightly blanch it for 1–2 minutes before adding it to the salad.
