This Rainbow Orzo Salad brings together a colorful mix of fresh vegetables, tender orzo pasta, and aromatic herbs, all tossed with a zesty lemon herb dressing. This is my go-to summer salad for family cookouts and backyard lunches because it feels light yet super satisfying. The best part is how quickly it comes together for potlucks or busy weeknights.
I first tried this recipe on a sunny July afternoon with my kids and they loved helping me chop all the vibrant veggies. Now it is our signature summer dish and always the first to disappear at gatherings.

Step-by-Step Instructions
- Cook the Orzo:
- Bring a big pot of water to a rolling boil and sprinkle in salt. Add the orzo and cook according to package directions until it is al dente which keeps the salad from turning mushy. Stir every few minutes to stop the pasta from sticking together. Once cooked drain right away and rinse under cold water until fully cooled so it stays separate and does not keep cooking in its own heat
- Make the Lemon Herb Dressing:
- While the orzo is cooking combine olive oil, lemon juice, red wine vinegar, Dijon mustard, garlic, oregano, salt, and black pepper in a jar or small bowl. Whisk until blended and emulsified so the oil and vinegar do not separate. Set aside so the flavors can blend together
- Combine Salad Ingredients:
- In a large mixing bowl toss together the cooked cooled orzo, chopped bell peppers, cucumber, red onion, corn, basil, and parsley. Pour the dressing over and stir well until everything is evenly coated and glossy
- Season and Marinate:
- Taste the salad and adjust with extra salt or pepper if needed. For even more flavor cover the bowl and let the salad chill in the fridge for a couple of hours or overnight. This helps the orzo and veggies soak up all the vibrant dressing flavors
- Serve:
- Just before serving toss again and garnish with extra herbs if desired. Serve chilled or at cool room temperature for the freshest flavor

Rainbow orzo salad is always the highlight of our picnic table. My favorite ingredient is the fresh basil which lifts the entire dish with its sweet aroma. One summer my niece and I picked basil right from our garden and that made the salad extra special for our family lunch.
Storage Tips
Store the salad in an airtight container in the fridge for up to four days. Because the dressing is oil based it will not make the veggies soggy. Give the salad a good toss before serving to redistribute the dressing and freshen up the herbs.
Ingredient Substitutions
Try whole wheat orzo or even small pasta shapes like ditalini for a different texture. Add crumbled feta cheese for a savory note or swap in chopped spinach or arugula for more greens. If you do not have red wine vinegar use white wine vinegar or apple cider vinegar.

Serving Suggestions
This salad pairs perfectly with grilled chicken, shrimp, or tofu on summer nights. It also makes a bright lunch on its own or served over leafy salad greens. Bring to barbecues, picnics or serve with pita and hummus for a Mediterranean twist.
Cultural and Historical Context
Orzo is a rice shaped pasta commonly found in the Mediterranean and Middle Eastern cuisines. Bright lemony salads like this one are traditional on tables from Greece to Italy especially in warm months when gardens are bursting with fresh vegetables and herbs.
