Dice the red and orange peppers into 1/4-inch pieces to match the size of the orzo kernels—this ensures even distribution throughout the salad. Dice the cucumber into similar-sized pieces, finely mince the red onion to distribute its flavor evenly, and measure out the corn. Roughly chop the basil and parsley, keeping them separate so the delicate basil doesn't bruise from the parsley's tougher texture. Mince the garlic cloves finely. Having everything prepped and ready before cooking ensures the salad comes together quickly once the orzo is cooked and cooled.
Bring a pot of salted water to a rolling boil—I use about 1 teaspoon of salt per cup of water for proper seasoning from the inside out. Add the orzo and cook according to package directions (typically 9-10 minutes), stirring occasionally to prevent sticking. I always reach for Barilla because it holds its al dente texture beautifully without becoming mushy. Drain the orzo in a colander and immediately rinse it with cold water while stirring gently to stop the cooking process and prevent clumping.
In a medium bowl, combine the olive oil, red wine vinegar, lemon juice (freshly squeezed for its necessary acidity and brightness), Dijon mustard, minced garlic, oregano, salt, and black pepper. Whisk vigorously for 30 seconds to emulsify the dressing, creating a cohesive sauce rather than separate oily and vinegary layers. This technique ensures the flavors meld and coat every component of the salad evenly. I prefer Filippi Berio Extra Virgin olive oil for dressings because its fruity notes complement the fresh vegetables beautifully.
Transfer the cooled orzo from Step 2 to a large mixing bowl. Add all the prepped vegetables from Step 1 (peppers, cucumber, red onion, and corn) along with the chopped basil and parsley. Pour the vinaigrette from Step 3 over the mixture and stir gently but thoroughly, using a large spoon or spatula to coat everything evenly with the dressing. Make sure to scrape the bottom of the bowl to incorporate any dressing that settles there.
Let the salad sit at room temperature for 10-15 minutes before serving to allow the orzo to fully absorb the dressing flavors. This resting period also lets the vegetables release their natural juices, which mixes with the vinaigrette to create a more cohesive dressing. Taste and adjust seasoning if needed with a pinch of salt or splash of lemon juice. Serve chilled or at room temperature depending on your preference.
