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, typically 8-10 minutes. Drain thoroughly, reserving 1/2 cup of the starchy cooking liquid. Set aside.
02 - While pasta cooks, heat olive oil in a large skillet over medium heat. Add minced garlic and sauté for approximately 1 minute until fragrant and lightly golden, taking care not to burn.
03 - Add diced zucchini, cherry tomatoes, 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 pasta cooking water. Add grated Parmesan, lemon zest, and fresh lemon juice. Toss vigorously until the sauce coats the pasta evenly and becomes creamy.
05 - Remove from heat. Season generously with salt and freshly ground black pepper to taste. Fold in chopped fresh basil and parsley until evenly distributed.
06 - Transfer to serving plates or bowls. Top with additional grated Parmesan and fresh herb garnish if desired. Serve immediately while hot.
