Ingredients
  

rotini pasta
  • 1 lb rotini pasta Cooked until al dente for best bite in pasta salad.
Italian dressing
  • 1 can (16 oz) Italian dressing Use bottled Italian dressing; reserve a splash to refresh after chilling.
cherry tomatoes
  • 1 cup cherry tomatoes, halved
cucumber
  • 1 cup cucumber, diced
green bell pepper
  • 1 cup green bell pepper, diced
red onion
  • 0.5 cup red onion, diced
black olives
  • 0.5 cup black olives, sliced
Parmesan cheese
  • 0.25 cup Parmesan cheese, grated Grate fresh for a better texture and melt-less coating.
Italian seasoning
  • 1 tsp Italian seasoning

Method
 

Cook and cool the pasta
  1. Cook rotini pasta according to package directions until al dente, then drain. Visual cue: pasta should be tender with a slight bite.
  2. Rinse the cooked pasta with cold water until fully cooled, then drain well. Visual cue: pasta looks less glossy and stops steaming.
Assemble and chill
  1. Combine pasta, cherry tomatoes, cucumber, green bell pepper, red onion, and black olives in a large bowl. Visual cue: vegetables are evenly distributed throughout.
  2. Add Italian dressing, Parmesan cheese, and Italian seasoning, then toss until everything is coated. Visual cue: pasta is slicked with dressing and vegetables look lightly glazed.
  3. Refrigerate for at least 2 hours to allow flavors to develop, covered if possible. Visual cue: mixture looks thicker and more cohesive as dressing clings.
  4. Toss again before serving and add more Italian dressing if needed. Visual cue: vegetables appear fresh and the coating looks even.

Notes

Pro tip: rinse pasta thoroughly and chill covered—warm pasta can dilute the dressing and soften vegetables. Refrigerate leftovers in an airtight container for up to 4 days; the texture is best within 2 days. Freezing isn’t recommended because vegetables turn watery after thawing. For a lighter option, use a reduced-fat Italian dressing to cut calories while keeping the same flavor profile.
