In a large pot, bring water to a boil and cook the orzo pasta according to package instructions. About one minute before the orzo is done, add the broccoli florets to the pot. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the diced chicken breast and season with salt, pepper, and dried thyme. Cook, stirring occasionally, until the chicken is cooked through and golden brown, about 5-7 minutes.
Add the minced garlic to the skillet and sauté for an additional minute until fragrant.
Pour in the chicken broth and lemon juice, scraping any bits from the bottom of the skillet. Bring to a simmer.
Add the cooked orzo and broccoli mixture to the skillet, tossing everything to combine. Allow it to cook for another 2-3 minutes until heated through.
If desired, sprinkle grated Parmesan cheese over the dish and stir until melted and creamy.
Adjust seasoning with more salt and pepper if needed. Serve warm, garnished with fresh parsley.
Notes
Optional to add Parmesan cheese for extra creaminess.
