Preparation
Step 1
Melt butter in Dutch oven over medium heat. Add onion and garlic and cook until onion is softened, about 4 minutes. Add orzo and cook until lightly toasted, about 3 minutes. Stir in broth, 1¼ teaspoons salt, ¼ teaspoon pepper, and saffron and bring to boil. Reduce heat to medium-low, cover, and simmer, stirring occasionally, until orzo is just tender, about 12 minutes.
Step 2
Pat shrimp dry with paper towels and sprinkle with remaining ½ teaspoon salt and remaining ¼ teaspoon pepper. Stir shrimp into risotto and cook, covered, until shrimp are opaque throughout, about 5 minutes. Off heat, stir in parsley and lemon zest and juice. Serve
