Recipe Instructions
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Add 12 oz rotini pasta and cook according to the package instructions, usually about 8–10 minutes, until tender.
Drain the pasta in a colander and let it cool for about 10 minutes so it doesn’t melt the cheese later.
Step 2: Prepare the Vegetables
While the pasta cools, prepare the vegetables.
- Dice 1 cup cucumber
- Dice ½ cup red onion
- Halve 1 cup cherry tomatoes
Set everything aside.
Step 3: Combine the Ingredients
In a large mixing bowl add:
- cooled 12 oz cooked rotini pasta
- 1 cup halved cherry tomatoes
- 1 cup diced cucumber
- ½ cup diced red onion
- ½ cup sliced black olives
- 1 cup mozzarella balls
Gently mix with a wooden spoon.
Step 4: Add Dressing and Seasoning
Pour ⅓ cup Italian dressing over the pasta salad. Add ½ teaspoon salt and ¼ teaspoon black pepper.
Toss everything together until the pasta and vegetables are evenly coated.
Step 5: Add Fresh Herbs and Finish
Sprinkle 2 tablespoons chopped fresh parsley over the salad and give it one final toss.
Serve immediately or refrigerate for 30 minutes for even better flavor.

Why This Recipe Works (Quick Science)
A few simple things make this pasta salad taste great.
- Salted pasta water seasons the pasta from the inside out.
- Cooling the pasta first prevents the cheese from melting and keeps the vegetables crisp.
- Italian dressing contains oil and vinegar, which coat the pasta and carry flavor to every bite.
- Rotini pasta holds dressing in its twists, which means better flavor in each forkful.
Pro Tips
- Let the pasta cool slightly before mixing so the cheese stays firm.
- If the salad seems dry later, add 1–2 tablespoons extra Italian dressing.
- Chill the salad 30–60 minutes before serving for deeper flavor.
- Cut vegetables into similar sizes so every bite has a balanced texture.
Substitutions and Variations
- Swap rotini with penne, fusilli, or bowtie pasta.
- Use feta cheese instead of mozzarella for a tangier flavor.
- Add chickpeas for extra protein.
- Try spinach or arugula for extra greens.
- Add roasted red peppers for a sweet smoky flavor.
Make Ahead Tips

Common Mistakes
Using hot pasta
Hot pasta will soften the vegetables and melt the cheese.
Not seasoning enough
Pasta absorbs flavor. Don’t skip the salt and pepper.
