How To Make Tri Color Pasta Salad
Bring a large pot of water to a full rolling boil over high heat, and use more water than you think you need because pasta likes room to move, not a tiny hot tub where it can sulk and stick together.
For 1 pound of rotini, use about 4 quarts of water and add 1 tablespoon of kosher salt once the water is boiling.
The water should taste lightly salty, not ocean-level dramatic, because this is your first chance to season the pasta from the inside.
Add tri color rotini and stir immediately for 20 to 30 seconds so the pieces do not cling together at the bottom of the pot like shy party guests.
Cook the pasta until it is just past al dente, usually 9 to 11 minutes depending on the brand, because cold pasta firms up as it chills.
Drain the pasta well, then rinse it under cool water for 15 to 20 seconds only.
Shake the colander firmly to remove extra water, because watery pasta salad tastes tired before it even reaches the table.
Spread the pasta on a large rimmed baking sheet or in a wide bowl for 5 minutes so steam can escape. This little step keeps the pasta from trapping moisture and turning the dressing thin.
While the pasta cools, make the dressing in a jar or medium bowl.
Add olive oil, red wine vinegar, lemon juice, Dijon mustard, honey, dried Italian seasoning, garlic powder, fresh garlic, salt, black pepper, red pepper flakes, and parmesan.
Shake the jar hard for 20 seconds or whisk until the dressing looks slightly creamy and blended.
Taste it with a piece of pasta, not just from a spoon, because dressing tastes stronger alone and more balanced once it hits pasta.
If it tastes too sharp, add another teaspoon of honey. If it tastes sleepy, add a pinch more salt or a splash of vinegar.
Pour about half of the dressing over the slightly warm pasta and toss it well. This is the move that separates a forgettable pasta salad from a great one.
Let the dressed pasta sit for 10 minutes while you chop the vegetables. It should look glossy, lightly coated, and fragrant with garlic and herbs.
Cut the cherry tomatoes in half so they release a little juice into the salad, but do not chop them so small that they collapse into tomato confetti.
Dice the cucumber and bell peppers into small, even pieces, about half an inch, because pasta salad is better when each forkful has pasta, crunch, cheese, and dressing together.
Slice the red onion thinly so it gives flavor without taking over the whole bowl like a relative with too many opinions.
If your onion tastes very sharp, soak the slices in cold water for 10 minutes, then drain and pat dry. That quick soak calms the bite while keeping the crunch.
Add tomatoes, cucumber, bell peppers, red onion, mozzarella pearls, olives, pepperoncini, parsley, basil, parmesan, and optional salami or turkey pepperoni to the bowl with the pasta.
Pour in most of the remaining dressing, saving 2 to 3 tablespoons for right before serving.
Toss gently but thoroughly with a large spoon or clean hands, lifting from the bottom so every piece gets coated.
Do not stir like you are mixing cement. You want the mozzarella to stay whole, the tomatoes to stay juicy, and the pasta to look glossy rather than battered.
Cover the bowl and refrigerate the salad for at least 1 hour. If you can give it 2 to 4 hours, even better!
If it looks a little dry, add the reserved dressing and 1 tablespoon of the saved pasta water if needed.
The pasta should look shiny and loose, not oily, not wet, and not clumped together like it is holding a meeting.
Taste before serving and adjust like a person who cares.
Add more salt if the flavors feel muted, more lemon juice if it needs brightness, more parmesan if you want a savory finish, or more pepperoncini if you want extra tang.
Finish with freshly cracked black pepper and a sprinkle of parsley or basil on top.
Serving Suggestions
Serve this tri color pasta salad with grilled chicken, burgers, baked salmon, turkey sandwiches, barbecue ribs, veggie skewers, or simple garlic bread.
It is also excellent with rotisserie chicken when dinner needs to happen fast and nobody has the emotional bandwidth to discuss chopping another onion.
For lunch meal prep, pack it with grilled chicken, chickpeas, tuna, or hard-boiled eggs.
If you want to keep it vegetarian but more filling, add 1 can of drained chickpeas or white beans. They soak up the dressing beautifully and make the salad feel more like a complete meal.
