This Italian orzo salad has been a summer staple in my kitchen for years, surfacing at backyard picnics, weeknight dinners, and those last-minute gatherings when I need something colorful and satisfying fast. I first combined these ingredients while cleaning out the pantry and fridge; a half jar of pesto, a bag of orzo, and a few odds and ends produced a dish everyone asked for again. The small, rice-shaped pasta holds dressing and ingredients beautifully, giving every bite a great balance of texture and flavor.

The salad sings with contrasts: bright, acidic little tomatoes; the briny pop of Castelvetrano olives; the savory chew of diced salami; and a silky dressing that is part pesto, part classic vinaigrette. Shaved parmesan adds a nutty finish and fresh basil threads give a final perfume. It keeps well chilled, makes an excellent make-ahead dish, and is easily scaled up for a crowd. Whenever I make it, neighbors end up lingering longer than planned — that kind of effortless crowd-pleaser stays on my rotation year-round.

Ingredients

• DeLallo orzo (1 cup): Choose a high-quality durum wheat orzo for a firm, slightly chewy bite; DeLallo is recommended for consistent texture and classic Italian pantry authenticity.
• Little tomatoes (1 cup, halved): Use grape or cherry tomatoes for sweetness and bright acidity; pick firm, glossy fruit for the best texture after chilling.
• Cucumber (3/4 cup, chopped): English or Persian cucumbers have fewer seeds and thinner skin, keeping the salad crisp and preventing excess moisture.
• Salami (1/2 cup, diced): Choose a mildly spiced cured salami for savory depth; slice consistently small so each bite has a balanced meat-to-veg ratio.
• Red onion (3 tablespoons, chopped): Mild red onion adds a sharp, sweet note; soak in cold water for 5 minutes to soften the bite if desired.
• Pepperoncini (1/3 cup, chopped): These add tang and subtle heat; drain and slice them thin to distribute their flavor evenly.
• DeLallo Castelvetrano or black olives (1/2 cup, sliced): Castelvetrano olives are buttery and mild; black olives offer a deeper, saltier profile—both work well.
• Shaved parmesan (1/2 cup): Freshly shaved Parmigiano-Reggiano provides savory, nutty richness; pre-shaved is a time-saver but fresh is superior.
• Fresh basil (2 tablespoons, thinly sliced): Adds aromatic lift; add last so it stays bright and avoids wilting in the dressing.
• Dressing: Olive oil (2 tablespoons), mayonnaise (2 tablespoons), white vinegar (2 tablespoons), DeLallo pesto (2 teaspoons), granulated sugar (1/2 teaspoon), Italian seasoning (1/2 teaspoon), salt and pepper to taste. Use good extra virgin olive oil for flavor, and a jarred pesto when you need convenience.

Instructions

Cook the orzo: Bring a large pot of water to a rolling boil and add a generous pinch of salt. Add 1 cup of orzo and cook according to package directions until al dente, usually about 8 to 9 minutes. Drain the orzo in a colander and immediately toss with about 1 teaspoon of olive oil to prevent sticking. Spread the drained pasta in the colander and allow it to cool fully to room temperature; this prevents the dressing from thinning and keeps the salad from becoming watery. Whisk the dressing: In a medium bowl, combine 2 tablespoons olive oil, 2 tablespoons mayonnaise, 2 tablespoons white vinegar, 2 teaspoons pesto, 1/2 teaspoon granulated sugar, and 1/2 teaspoon Italian seasoning. Whisk until smooth and emulsified. Taste and adjust acidity or salt; the mayo gives body while the vinegar and pesto give brightness and herbaceous depth. Prep the mix-ins: While the pasta cools, halve the tomatoes, chop the cucumber, dice the salami, thinly slice the red onion, and chop the pepperoncini. Slice olives and shave the parmesan. Keep the basil until the end to preserve freshness. Assemble the bowl: Transfer the cooled orzo to a large salad bowl. Add the tomatoes, cucumber, salami, red onion, pepperoncini, olives, and shaved parmesan. Pour the dressing over the ingredients and toss gently but thoroughly until everything is evenly coated. Taste and season with additional salt and fresh cracked pepper as needed. Rest or serve: Serve immediately for a bright, fresh texture, or cover and chill for at least 1 to 2 hours to allow flavors to meld. If chilling, remove from refrigerator 15 minutes before serving and toss again with a splash of olive oil if the pasta seems dry.

Storage Tips

Store the salad in an airtight container in the refrigerator for up to 3 days. Use a shallow container to keep the salad chilled quickly and avoid bacterial growth. If you plan to make it ahead, under-dress by about a quarter and reserve a tablespoon or two of dressing to refresh the bowl before serving; this prevents the pasta from soaking up all the dressing and becoming dry. For best texture, add the basil and parmesan just before serving. Refrigerate any leftovers within two hours of serving.

Ingredient Substitutions

For a vegetarian bowl, swap the salami for marinated artichoke hearts or roasted chickpeas for a similar savory bite. To make it lighter, replace half the mayonnaise with plain Greek yogurt for tang and protein. Swap Castelvetrano olives for Kalamata if you prefer a darker, more assertive olive flavor. For a gluten-free option, choose a rice-shaped gluten-free pasta or cooked quinoa; expect a slightly different mouthfeel but similar flavor balance.

Serving Suggestions

Serve this bowl chilled as a side to grilled chicken, shrimp, or a simple roasted vegetable board. It pairs well with crisp white wine or a sparkling water with lemon. Garnish with additional shaved parmesan and a drizzle of extra virgin olive oil for sheen. For a picnic, pack in a cooler with ice packs and a separate small container of fresh basil to add just before serving.

Cultural Background

Orzo, an Italian pasta shaped like a large grain of rice, is versatile in Mediterranean cooking. This style of tossed orzo salad blends traditional Italian flavor components—olive oil, vinegars, cured meats, olives, and hard cheese—with an American picnic sensibility. While not a heritage dish from a single region, the salad borrows classic Italian pantry items and reinterprets them in a casual, shareable format that became popular in Italian-American gatherings.

Seasonal Adaptations

In summer, emphasize fresh tomatoes and basil; in cooler months, swap tomatoes for roasted red peppers and use arugula instead of basil for peppery depth. Around holidays, add roasted butternut squash, toasted pine nuts, and crisp pancetta for a heartier version. Adjust the dressing acidity slightly depending on produce sweetness—ripe summer tomatoes need less vinegar than winter varieties.

Meal Prep Tips

Make the orzo and dressing up to two days ahead and store separately. Chop vegetables the night before and keep them in airtight containers to maintain crispness. When assembling for lunches, portion into individual containers and add basil and parmesan just before eating to preserve texture. Use clear containers so you can see what needs finishing touches at serving time.

With simple steps and bold, complementary ingredients, this Italian orzo salad is one of those dishes I return to again and again. It travels well, scales effortlessly, and invites improvisation—just the kind of recipe that becomes part of a family rotation.
