01 - Bring 6 cups water and 1 tsp salt to a boil in a large pot. Add orzo and cook according to package directions until al dente. Drain and set aside, reserving 1/2 cup of the cooking liquid.
02 - Heat olive oil in a large skillet over medium heat. Add minced garlic and sauté for 1 minute until fragrant, being careful not to brown.
03 - Add diced zucchini, cherry tomatoes, yellow bell pepper, asparagus pieces, and peas to the skillet. Sauté for 4–5 minutes, stirring occasionally, until vegetables are tender-crisp.
04 - Add the drained orzo to the skillet with the sautéed vegetables. Pour in the reserved pasta water, then stir in grated Parmesan, lemon zest, and lemon juice. Toss everything together until well combined and the sauce becomes creamy.
05 - Season generously with salt and black pepper to taste. Remove from heat and fold in chopped fresh basil and parsley.
06 - Transfer to a serving platter or individual bowls. Top with additional grated Parmesan and fresh herbs if desired. Serve immediately while hot.
