Do I have to make homemade dressing, or can I use bottled Italian dressing?
You can absolutely use bottled. You will need about 3/4 cup, and it is smart to hold back a few tablespoons to refresh right before serving. If the bottle is very sweet, add a squeeze of lemon or a splash of red wine vinegar to sharpen it up.
How do I keep pasta salad from getting dry?
Toss the pasta with a few tablespoons of dressing while it is still slightly warm, then add more after it cools. Also, reserve a little dressing to stir in right before serving (pasta gets thirsty in the fridge).
Should I rinse the pasta?
Yes for pasta salad. Give it a quick rinse (about 10 to 15 seconds) under cold water. You are cooling it down and stopping carryover cooking, not chilling it into “ice cold pasta” territory.
What pasta shape works best?
Short shapes with grooves and twists are the move. Rotini, fusilli, farfalle, and penne all grab dressing well.
Can I make it the night before?
That is the sweet spot. Make it 4 to 24 hours ahead, then taste and adjust with a pinch of salt, a crack of pepper, and a little extra dressing right before serving.
My onion or garlic tastes too sharp. How do I fix it?
Let the salad chill for at least 30 minutes, then taste again, since the bite softens as it sits. If you know you are sensitive to raw onion, soak the sliced onion in cold water for 5 to 10 minutes and drain, or swap in shallot. For garlic, grate it super fine and do not overdo it. Two small cloves is plenty.
How can I add protein?
Try diced salami, pepperoni, shredded rotisserie chicken, chickpeas, or white beans. Keep portions bite-sized so every forkful gets some.
