In a small saucepan, add the orzo and butter and place over medium heat.
Stir frequently and cook for about 2–3 minutes until the orzo is lightly toasted and the butter is melted.
Add the chicken broth and garlic powder to the saucepan and reduce the heat to low.
Simmer gently, stirring regularly, until the broth is absorbed and the orzo is tender, about 8–10 minutes. Keep the heat low so the broth absorbs evenly.
Remove from heat and stir in the freshly grated Parmesan until melted and combined.
Serve immediately.
