In a large pot, bring chicken broth to a boil and add the orzo pasta.
Cook orzo for 8-10 minutes until al dente, draining any excess liquid if necessary.
While orzo cooks, heat olive oil in a large skillet over medium-high heat.
Add shrimp to the skillet in a single layer, seasoning with salt and pepper.
Sear shrimp for 2 minutes per side until pink and opaque, then remove from skillet and set aside.
In the same skillet, melt butter and add minced garlic, sautéing for 1 minute until fragrant.
Stir in lemon juice and lemon zest, scraping the bottom of the pan for flavor.
Add the cooked orzo and sautéed shrimp back into the skillet.
Toss all ingredients together for 1-2 minutes until thoroughly coated and heated through.
Garnish with fresh parsley and serve immediately.
