Ingredients You’ll Need

Tri-color rotini is the best pasta choice for the classic rainbow appearance, and its spirals hold onto the vinaigrette beautifully. Fusilli works well too, especially when that is what you have in the pantry.
The vegetable combination is designed to give each bite a different texture. Cherry tomatoes add juicy sweetness, cucumber brings cool crunch, bell peppers provide brightness, broccoli adds a firm bite, red onion contributes gentle sharpness, and black olives bring a salty finish.
For the cheese, crumbled feta gives the salad a tangy Mediterranean character. Small mozzarella balls make it milder and creamy, so choose the option that best suits your table.
The homemade dressing uses extra-virgin olive oil, red-wine vinegar, lemon juice, Dijon mustard, honey or sugar, garlic, Italian seasoning, salt, and pepper. The small amount of honey or sugar rounds out the vinegar without making the dressing sweet.
If time is short, use 3/4 to 1 cup of bottled Italian dressing instead. The homemade version has a fresher citrus-and-garlic flavor, while the bottled option makes this recipe especially convenient for busy days.
How to Make It Step-by-Step

Step 1: Bring a large pot of generously salted water to a boil, then add the tri-color rotini or fusilli. Cook it according to the package directions until al dente, usually 9–12 minutes, checking near the lower end of the range so the pasta stays pleasantly firm after chilling.
Step 2: Drain the pasta as soon as it reaches the right texture and rinse it briefly under cold water. This stops the cooking process and cools the spirals, but be sure to drain them thoroughly because standing water can make the finished dressing taste thin.
Step 3: While the pasta cooks, prepare the produce and cheese. Halve the cherry tomatoes, dice the cucumber and both bell peppers, cut the broccoli into small florets, thinly slice or finely dice the red onion, slice the olives, and measure the feta or mozzarella.
Step 4: Make the dressing in a bowl by whisking together the olive oil, red-wine vinegar, lemon juice, Dijon mustard, honey or sugar, minced garlic, Italian seasoning, salt, and pepper. For a quick alternative, add everything to a jar, secure the lid, and shake until combined.
Step 5: Place the cooled pasta in a large mixing bowl with the tomatoes, cucumber, red and yellow bell peppers, broccoli, onion, olives, and cheese. Pour in about three-quarters of the dressing, then toss gently so the vegetables stay crisp and the cheese does not break apart too much.
Step 6: Cover the bowl and refrigerate for at least 30 minutes. Before serving, toss again and add the reserved dressing if the pasta has absorbed too much, then scatter chopped parsley over the top.

Chef Tips for the Best Pasta Salad

The most important detail is cooking the pasta only to al dente. Overcooked rotini becomes soft as it absorbs dressing in the refrigerator, while firm pasta keeps the salad lively and pleasant to eat.
Cut the vegetables into pieces that are roughly similar in size to the pasta. This helps every serving include a balanced mix instead of leaving large pieces at the bottom of the bowl or making the salad awkward to scoop.
- Drain well: Give the rinsed pasta time to release excess water before combining it with the dressing.
- Use a large bowl: Extra space makes gentle tossing easier and helps distribute the vegetables evenly.
- Reserve dressing: Keep about one-quarter aside for a fresh final toss before serving.
- Chill before serving: Thirty minutes allows the vinaigrette to reach the pasta and vegetables.
- Season thoughtfully: Olives and feta already bring salt, so taste before adding anything beyond the listed dressing.
For the best visual effect, keep the red and yellow pepper pieces distinct and place a few tomato halves, olives, and parsley leaves on top just before serving. The salad should be chilled or cool rather than served hot.
Serving Ideas and Variations

This pasta salad fits naturally beside grilled chicken, burgers, sandwiches, or picnic fare. It can serve as a generous side dish for 6–8 people, or as a light lunch when you want a colorful bowl that needs no reheating.
Feta gives the recipe a salty, tangy bite, while mozzarella pearls create a softer and more delicate taste. Both are included in the ingredient guidance, so there is no need to change the dressing when switching between them.
Fresh parsley is optional, but it adds a clean herbal note and a final touch of green. Add it after chilling so it remains bright and fragrant.
If you are planning a casual spread, serve this alongside a seafood starter such as a crab meat salad appetizer. For a comforting main-course pairing, an easy taco pie brings warm, savory contrast to the cool salad.
Storage and Make-Ahead Advice
Store the finished salad covered in the refrigerator and enjoy it within up to 2 days for the best texture. The pasta will continue absorbing the vinaigrette as it rests, so the reserved dressing is especially useful after storage.
When ready to serve, take the salad from the refrigerator, toss it gently, and add the remaining dressing a little at a time. This restores moisture and brings the vinegar, lemon, garlic, and herbs back into focus without making the vegetables soggy.
It is best served chilled or cool. Avoid leaving it out longer than necessary at a warm gathering, and return leftovers to the refrigerator promptly.
