Easy Pasta Salad Recipe (Ready in 20 Minutes)

This easy pasta salad is the side dish I keep coming back to from Memorial Day through Labor Day, and honestly, well past the leaves turning. It's bright, zippy, packed with crunchy veggies and creamy little mozzarella pearls, and tossed in a from-scratch zesty Italian vinaigrette that hits every corner of the bowl. No mystery bottled dressing, no soggy noodles, no sad-looking penne hiding under a slick of mayo.

The best part: start to finish, it's twenty minutes. Boil the pasta, chop while it cooks, whisk the dressing in a jar, toss it all together. Done. Whether you're feeding a backyard crowd, packing lunches for the week, or just craving something cool and herby with dinner tonight, this one earns its keep.

I've made this recipe roughly a hundred times for cookouts, beach days, and last-minute gatherings, and the feedback is always the same — people ask for the recipe before they finish their plate. The trick? A homemade dressing with real bite, and a "dress it twice" technique that keeps every bite glossy instead of dry, even on day three.

What Makes This Easy Pasta Salad Stand Out

Most pasta salad recipes lean on bottled Italian dressing as a shortcut, and you can absolutely taste it — that flat, oversweet, slightly chemical edge that screams grocery aisle. This recipe skips all that. The dressing comes together in a mason jar with olive oil, red wine vinegar, garlic, and dried herbs, and it tastes like a real Italian vinaigrette should: punchy, herby, balanced.

The other thing that sets this apart is technique. Pasta is a sponge — it drinks up dressing as it sits. So instead of tossing once and hoping for the best, we dress the pasta lightly while it's still slightly warm (it absorbs the flavor better that way), then add the rest of the dressing right before serving. The result is a simple pasta salad that stays flavorful and never tastes dry, even after a day in the fridge.

It also fits into nearly any menu. It's substantial enough to anchor a vegetarian dinner, light enough to play sidekick to grilled steak, and travels like a champ to any gathering. If you've been hunting for reliable potluck recipes that don't require a casserole dish or a serving spoon you'll never see again, this is the one to bookmark.

Ingredients You'll Need

Almost everything here is a pantry-and-produce-drawer staple, which is part of why this recipe gets made so often around here. You probably have most of it on hand already, and what you don't is a quick run to the corner store away.

Pick the Right Pasta Shape

When it comes to the best pasta to use for a cold pasta dish, you want short, sturdy shapes with ridges or curves. Penne is my go-to — the diagonal cut and grooved exterior grab the dressing and hold it. Rotini, fusilli, farfalle (bowties), and cavatappi all work beautifully too. Skip long noodles like spaghetti or angel hair — they tangle and turn soggy — and avoid delicate shapes like orzo unless you're going for a totally different texture. A good bronze-cut pasta will give you the best surface for the dressing to cling to, but any sturdy supermarket brand will do the job.

The Fresh Stuff

Cherry tomatoes give you sweet little bursts in every bite, and they hold up better than slicing tomatoes, which can turn watery overnight. English cucumber stays crunchy because it has fewer seeds and thinner skin (no peeling required). Red bell pepper adds sweetness and color, red onion brings a sharp bite, and black olives add briny depth. Mozzarella pearls — those tiny fresh balls — are the secret weapon: creamy, mild, and perfectly sized so you don't need to chop anything.

The Zesty Italian Dressing

This is where the magic happens. A good homemade Italian dressing comes together in under two minutes: olive oil, red wine vinegar, a minced garlic clove, dried Italian seasoning, salt, pepper, and a pinch of sugar to balance the acid. Shake it in a mason jar and you're done. Fresh parsley folded in at the end brightens the whole bowl. If you've got fresh basil or oregano on hand, even better — chop a tablespoon and stir it through right before serving.

How to Make Easy Pasta Salad Step by Step

Step 1: Boil the Penne

Bring a large pot of water to a rolling boil and salt it generously — and I mean generously, like a tablespoon of kosher salt for a big pot. This is your one shot to season the pasta from the inside. Cook the penne to al dente according to the package, usually 9 to 11 minutes. Drain it and immediately rinse under cold running water. Yes, rinse — this is a cold pasta dish, and rinsing stops the cooking, washes off excess starch (which would otherwise turn the dressing gummy), and brings the temperature down so the dressing doesn't get drunk up too fast. Shake out as much water as you can.

Step 2: Prep the Vegetables

While the pasta cooks, knock out the chopping. Halve the cherry tomatoes, dice the cucumber and bell pepper into pieces roughly the size of the penne so every forkful gets a little of everything, finely dice the red onion (smaller than the rest — raw onion is potent), and slice the olives if they aren't already. Mince the garlic for the dressing. Twenty minutes from boil to bowl really does come down to good multitasking here.

Step 3: Whisk the Dressing

In a small mason jar or measuring cup, combine the olive oil, red wine vinegar, minced garlic, Italian seasoning, a pinch of sugar, and a generous pinch of salt and cracked pepper. Screw the lid on and shake hard for 15 seconds, or whisk until emulsified and slightly creamy-looking. Taste it — it should be bright and bracing, almost too tangy on its own. That's exactly what you want, because the pasta and veggies will mellow it once everything comes together.

Step 4: Toss, Then Toss Again

In your largest bowl, combine the drained pasta with the tomatoes, cucumber, bell pepper, red onion, olives, mozzarella pearls, and chopped parsley. Pour over about two-thirds of the dressing and toss until everything is coated. Cover and chill for at least 15 minutes if you have time, or up to 24 hours. Right before serving, give it a stir and add the remaining dressing to wake everything back up. This double-dressing move is the single biggest difference between a great penne pasta salad and a sad, dry one.

Serving Suggestions

This salad is a chameleon. Pile it next to grilled chicken thighs, smoky BBQ ribs, or burgers and it disappears within minutes. As one of those summer cookout sides that genuinely earns its place on the table, it pairs especially well with anything off the grill — sausages, kabobs, lemon-pepper salmon. Add a basket of crusty bread and a chilled rosé and call it dinner.

It also pulls double duty as a main course. Stir in shredded rotisserie chicken, cubed salami, white beans, or a can of drained chickpeas to turn it into one of those quick weeknight dinners that doesn't require turning on the oven on a 90-degree day. Pack it into a thermos for the beach, scoop it into lunch containers for the week, or set it out at the start of a party so it's ready when guests are. Of all the make-ahead salads in my rotation, this is the one I trust to taste even better tomorrow than it does today.

Once you've made this easy pasta salad once, you'll see how flexible it is. Toss in whatever's lonely in the produce drawer — artichoke hearts, sun-dried tomatoes, roasted red peppers, baby arugula, capers. Swap the mozzarella for crumbled feta or goat cheese. Add a handful of toasted pine nuts for crunch. The bones of the recipe — al dente pasta, sharp homemade vinaigrette, the dress-it-twice trick — will carry whatever you throw at it. That's why it's earned its permanent spot in my summer rotation, and I have a feeling it'll do the same in yours.
