• 1½ cups (225 g) cherry tomatoes, halved
• 1 medium cucumber, seeded and chopped (about 1½ cups/200 g)
• 1 red bell pepper, small dice (about 1 cup/150 g)
• ½ small red onion, very thinly sliced (about ½ cup/50 g)
• ½ cup (70 g) pitted Kalamata olives, halved
• ½ cup (60 g) sliced pepperoncini or mild banana peppers
• 6 oz (170 g) mozzarella pearls or 4 oz (115 g) feta, crumbled (optional)
• ¼ cup (15 g) chopped fresh parsley
• ¼ cup (10 g) torn fresh basil, plus more for serving

Homemade Italian Dressing

• ⅓ cup (80 ml) extra-virgin olive oil
• 3 tbsp (45 ml) red wine vinegar
• 1 tbsp (15 ml) fresh lemon juice
• 1 tsp Dijon mustard
• 1 small garlic clove, finely grated
• 1 tsp dried oregano
• ½ tsp dried basil
• ¼ tsp red pepper flakes
• ½ tsp fine sea salt, plus more for pasta water
• Freshly ground black pepper
• ½ tsp honey or maple syrup (optional, to balance acidity)

Optional Add-Ins

• Artichoke hearts, sun-dried tomatoes, roasted red peppers
• Chickpeas for plant protein or chopped salami for a classic antipasto vibe
• Freshly grated Parmesan for serving

Step-by-Step Instructions

1. Boil the pasta: Bring 4 quarts (3.8 L) of water to a rolling boil. Salt generously (about 2 tbsp kosher salt). Add pasta and cook until just al dente, checking the package’s low end for timing.
2. Cool it right: Drain and rinse the pasta under cool water for 10–15 seconds to stop cooking and remove excess surface starch. Shake the colander well to dry. Spread on a sheet pan to steam off moisture while you make the dressing.
3. Make the dressing: In a jar, whisk or shake together olive oil, red wine vinegar, lemon juice, Dijon, garlic, oregano, dried basil, red pepper flakes, salt, and a few grinds of pepper. Add honey or maple if you prefer a rounder finish.
4. Layer the flavor: Transfer pasta to a large bowl and toss with about one-third of the dressing. Let sit 10 minutes so the pasta absorbs flavor and doesn’t clump.
5. Add the mix-ins: Fold in tomatoes, cucumber, bell pepper, red onion, olives, pepperoncini, and cheese (if using). Toss with most of the remaining dressing.
6. Chill and finish: Refrigerate 30–60 minutes to marry flavors. Before serving, add herbs, any reserved dressing, and a drizzle of olive oil if needed. Taste and adjust salt, pepper, or acidity.

Pro Tips for Perfect Pasta Salad

• Season the water heavily so the pasta is flavorful throughout.
• Rinse briefly to cool, but drain very well—excess water dilutes dressing.
• Toss pasta while slightly warm with some dressing to prevent sticking.
• Cut vegetables small and consistent for balanced bites.
• Hold back a little dressing to refresh just before serving.

Common Mistakes to Avoid

• Overcooking pasta, which turns mushy after chilling.
• Under-salting the water, leading to bland salad.
• Adding all the herbs early; fresh herbs are brightest at the end.
• Watery salad from unseeded cucumbers or poorly drained pasta.
• Overloading with too many mix-ins; keep a 60:40 pasta-to-veg ratio.

Recommended Tools

• 6–8 quart stockpot and sturdy colander
• Large mixing bowl and salad tongs
• Cutting board and sharp chef’s knife
• Jar with lid for shaking dressing
• Microplane or fine grater for the garlic and Parmesan

Variations & Swaps

• Antipasto: Add artichoke hearts, roasted red peppers, chopped salami, and provolone.
• Mediterranean: Use chickpeas, sun-dried tomatoes, cucumber, and feta with extra oregano.
• Grilled Veg: Fold in grilled zucchini, corn, and red onion for smoky depth.
• Pesto Vinaigrette: Whisk 2 tbsp pesto into the dressing for herby richness.
• Gluten-Free: Use brown rice or chickpea pasta; cook just shy of al dente.
• Dairy-Free/Vegan: Omit cheese or use a vegan feta; add capers for extra brininess.

Make-Ahead, Storage & Food Safety

• Make up to 24 hours ahead; reserve some dressing and fresh herbs to add before serving.
• Refrigerate in an airtight container for 3–4 days; flavors mellow and improve.
• Refresh with a squeeze of lemon, pinch of salt, and drizzle of oil on day two.
• Outdoor events: Keep chilled at or below 40°F (4°C) and limit to 2 hours at room temp.

FAQ

Can I make Italian pasta salad the day before?

Yes. Assemble the salad up to 24 hours ahead, but reserve a handful of herbs and 2–3 tablespoons of dressing. Before serving, toss in the reserved dressing and herbs to brighten flavors and revive texture. Taste and adjust salt, pepper, or lemon for a just-made finish.

What pasta shape works best for pasta salad?

Short, ridged shapes like rotini, fusilli, and farfalle grab onto dressing and veggies for balanced bites. Avoid long noodles, which tangle, and tiny shapes that turn mushy. Cook just to al dente so the pasta remains pleasantly firm after chilling.

Should I rinse pasta for cold pasta salad?

A brief rinse stops carryover cooking and removes excess surface starch, helping prevent clumping in cold salads. Drain very well after rinsing, then toss the pasta with a portion of the dressing while still slightly warm so it absorbs flavor and stays silky, not watery.

How do I keep pasta salad from getting soggy or watery?

Seed cucumbers, drain olives and pepperoncini, and shake the pasta dry after rinsing. Dress in stages—some right after cooking, the rest before serving. Chill briefly to allow flavors to meld, but avoid over-marinating delicate veggies for days on end.

Can I use bottled Italian dressing?

Yes, but choose a high-quality brand and taste before using. Brighten it with fresh lemon juice and black pepper, and add extra-virgin olive oil if it tastes thin. Homemade dressing is typically fresher and less sweet, but a good bottle works in a pinch.

How can I make this gluten-free or vegan?

Use a gluten-free short pasta and cook slightly shy of al dente. For vegan, omit dairy cheese or swap in a plant-based feta. Boost savoriness with olives, capers, or nutritional yeast, and add chickpeas for protein and extra heartiness.

How long does Italian pasta salad last in the fridge?

Properly stored in an airtight container, it keeps 3–4 days. The flavors deepen by day two. Before serving leftovers, add a splash of lemon juice or vinegar and a drizzle of olive oil to reawaken the dressing, then taste and re-season as needed.
