Step-by-Step Method

Boil the Pasta

Bring a large pot of water to a rolling boil. Add 1 tablespoon of salt to season the water well. Add the short pasta and cook according to package directions until just al dente.

Stir occasionally to prevent sticking. Avoid overcooking so the pasta holds its shape in the salad.

Cool and Drain the Pasta

Drain the cooked pasta in a colander. Rinse immediately under cold running water to stop the cooking and cool it down.

Toss gently while rinsing so all pieces cool evenly. Let the pasta drain very well to remove excess water, which helps the dressing cling better later.

Prep the Vegetables and Cheese

Place a cutting board on a stable surface. Halve the cherry tomatoes and dice the cucumber and red bell pepper.

Finely chop the red onion. Slice the black olives. Cube the mozzarella and grate the parmesan. Chop the fresh parsley. Keep ingredients in small piles for easy assembly.

Combine Pasta and Mix-Ins

Transfer the cooled, well-drained pasta to a large mixing bowl. Add the cherry tomatoes, cucumber, red bell pepper, red onion, black olives, mozzarella, parmesan, and parsley.

Gently toss with a wooden spoon or spatula to distribute the ingredients evenly throughout the pasta before adding the dressing.

Make the Dressing

In a small bowl or jar with a lid, add the olive oil, red wine vinegar, Dijon mustard, dried Italian seasoning, garlic powder, salt, and black pepper.

Whisk vigorously or secure the lid and shake until the mixture looks thickened and fully emulsified, with no large oil streaks remaining.

Dress and Toss the Salad

Pour the emulsified dressing evenly over the pasta and vegetables. Use a wooden spoon or spatula to toss gently until everything is thoroughly coated. Scrape the sides and bottom of the bowl so no dressing is left behind.

Assure the cheese and vegetables are well distributed throughout the salad.

Chill and Adjust Seasoning

Cover the bowl tightly and refrigerate for at least 30 minutes to let flavors meld. Before serving, toss the salad again.

Taste and adjust with extra salt and pepper if needed. If it seems a bit dry after chilling, add a small drizzle of olive oil or splash of vinegar, then toss once more.

Ingredient Swaps

• Pasta: Use whole wheat, chickpea, or lentil pasta for more protein/fiber; gluten‑free pasta for GF diets.
• Cheese: Swap mozzarella with feta, cheddar, or a dairy‑free cheese to keep it vegan.
• Veggies: Sub in whatever’s on hand—carrots, celery, broccoli, zucchini, or corn all work well.
• Olives & onion: Use green olives, capers, or omit for milder flavor; swap red onion with scallions or shallots.
• Dressing: Replace red wine vinegar with white wine vinegar, apple cider vinegar, or lemon juice; use Italian dressing or vinaigrette if you’re short on time.

You Must Know

– Make-Ahead – For best texture 1 day ahead, keep the dressing in a jar and the cut veggies and cheeses in separate containers, all chilled; combine everything 30–60 minutes before serving so the vegetables stay crisp and the cheese edges don’t get soggy.

Serving Tips

• Serve in a large chilled bowl, garnished with extra parsley and parmesan.
• Pair with grilled chicken, shrimp, or steak for a complete summer meal.
• Offer lemon wedges and extra dressing on the side for customizable flavor.
• Spoon into individual cups or jars for picnics, potlucks, or lunchboxes.
• Serve alongside garlic bread and a simple green salad for an easy dinner.

Storage & Make-Ahead

This cold pasta salad keeps well in the refrigerator for up to 3 days in an airtight container.

It’s ideal to make a few hours ahead so flavors meld; toss again before serving.

This salad doesn’t freeze well—freezing alters pasta texture and makes the vegetables watery.

Reheating

Reheat small portions briefly in the microwave with a splash of water, covered.

For larger amounts, warm in a covered oven-safe dish or gently on the stovetop, stirring frequently.

Potlucks and Backyard Barbecues

Once you’ve figured out how you like to serve your pasta salad at home—chilled from the fridge or just barely warm—it quickly becomes the kind of dish you want to carry to every potluck and backyard barbecue.

I love walking into a yard full of folding chairs and smoky grills, cradling a big chilled bowl like a summer offering.

This salad always disappears faster than the burgers. The colors—ruby tomatoes, cool cucumber, dark olives—look like confetti in the sunshine.

I usually tuck the bowl into a bigger bowl of ice so it stays cold while everyone wanders back for seconds. You don’t need to fuss; just give it a quick toss, set out a big spoon, and let it become the quiet star of the table.

Final Thoughts

Give this cold pasta salad a try and see how easy it’s to customize with your favorite veggies, cheeses, or add-ins.

Don’t be afraid to tweak the dressing or mix-ins to make it perfectly your own.
