Start by seasoning the chicken breasts generously with salt, pepper, and half of the lemon zest, ensuring to coat both sides evenly for maximum flavor.
In a large skillet, heat olive oil over medium heat until shimmering. Carefully add the seasoned chicken breasts to the skillet. Cook for approximately 5-6 minutes on each side, or until the chicken is golden brown and fully cooked through (internal temperature should reach 165°F/75°C). Once cooked, remove the chicken from the skillet and set it aside on a plate to rest.
Without cleaning the skillet, add the finely chopped onion and sauté for 3-4 minutes, stirring occasionally, until the onion is translucent and fragrant.
Add the minced garlic and sliced mushrooms to the skillet, continuing to cook for about 5 minutes. Stir occasionally until the mushrooms become tender and start to release their moisture.
Next, sprinkle the orzo pasta into the skillet, stirring well to combine it with the onions and mushrooms. Toast the orzo for about 2 minutes by stirring continuously to enhance its flavor.
Slowly pour in the chicken broth while stirring to combine. Season with additional salt and pepper to taste. Increase the heat and bring the mixture to a gentle boil, then reduce the heat immediately to a simmer.
Return the cooked chicken breasts to the skillet, placing them back into the orzo mixture. Cover the skillet with a lid and let it simmer for 10-12 minutes, or until the orzo is cooked al dente and has absorbed most of the broth.
Once the cooking time is complete, remove the lid and stir in the lemon juice, the remaining lemon zest, along with the chopped parsley and oregano. Gently mix to ensure all flavors meld together beautifully.
Serve the dish hot, with a generous sprinkle of freshly grated Parmesan cheese on top for that perfect finishing touch.
