01 - Bring 6 cups water and 1 tsp salt to a rolling boil in a large pot. Add orzo and cook according to package directions until al dente, approximately 8-10 minutes. Drain thoroughly, reserving 1/2 cup of the starchy cooking liquid for the sauce.
02 - While pasta cooks, heat 2 tbsp olive oil in a large skillet over medium heat. Add minced garlic and sauté for 60 seconds until fragrant, being careful not to brown or burn the garlic.
03 - Add diced zucchini, halved cherry tomatoes, diced yellow bell pepper, asparagus pieces, and peas to the skillet. Cook for 4-5 minutes, stirring occasionally, until vegetables are tender-crisp and brightly colored.
04 - Add the drained orzo to the skillet with the sautéed vegetables. Pour in the reserved 1/2 cup pasta water, 1/2 cup grated Parmesan, lemon zest, and lemon juice. Toss vigorously until the cheese melts and creates a creamy coating that clings to the pasta and vegetables.
05 - Remove the skillet from heat. Season generously with salt and freshly ground black pepper to taste. Gently fold in chopped fresh basil and parsley until evenly distributed throughout the dish.
06 - Transfer the orzo primavera to serving plates or bowls. Top with additional grated Parmesan and fresh herbs if desired. Serve while hot and enjoy with a crisp white wine such as Pinot Grigio.
