Step-by-Step Instructions
- Cook the Pasta:
- Boil the spaghetti in heavily salted water until just al dente about 8 to 9 minutes. The pasta will continue absorbing flavors once mixed with dressing so slightly undercooking prevents mushiness. Immediately rinse under cold water to stop the cooking process and drain thoroughly.
- Prepare the Vegetables:
- Slice and dice all vegetables to roughly the same size for balanced bites. The cucumber should be about the same size as the cherry tomato halves while the bell pepper and red onion should be cut slightly smaller. This attention to detail ensures perfect forkfuls with multiple flavors.
- Combine Components:
- In your largest mixing bowl gently toss the cooled pasta with all prepared vegetables. The wide surface area allows for thorough mixing without crushing delicate ingredients. Add the Parmesan and olives last to prevent them from breaking down.
- Dress and Season:
- Pour the Italian dressing evenly over the salad and toss gently but thoroughly to coat each strand of pasta. Sprinkle the Italian seasoning salt and pepper while continuing to toss ensuring even distribution. The pasta will quickly absorb the dressing so be generous.
- Chill and Marry Flavors:
- Cover the bowl tightly and refrigerate for at least one hour though overnight is preferable. This resting period allows the flavors to meld together and penetrate the pasta. The salad actually improves with time making it perfect for advance preparation.
The Italian dressing is truly the magic ingredient in this recipe. I discovered that using half store bought and half homemade dressing creates the perfect balance of convenience and fresh flavor. My grandmother taught me this trick and I have never looked back since.
