Can I make this salad ahead of time?
Yes. Assemble it 4-6 hours or up to 1 day ahead. Store covered in the refrigerator. The flavors deepen as it sits. Stir before serving.
What pasta shape works best for this salad?
Radiatore is ideal because its ridged, tubular shape traps the creamy dressing. Short pastas like rotini, penne, or fusilli are good substitutes.
How do I prevent the salad from getting dry?
Don't skimp on the dressing. The mayo and olive oil keep it creamy. If it dries out after a day, whisk in 1-2 tbsp olive oil or mayo before serving.
Can I use fresh mozzarella instead of mozzarella pearls?
Fresh mozzarella balls (bocconcini) work well. Avoid shredded mozzarella, which becomes clumpy. Add it just before serving to prevent it from breaking down.
Is this gluten-free?
Only if you use gluten-free pasta. Check that your Italian dressing mix packet is certified gluten-free, as some brands contain gluten.
