01 - Rinse rice under cold water until water runs clear. Combine rice, water, and salt in a medium saucepan. Bring to boil, reduce heat to low, cover, and simmer for 15 minutes or until water is absorbed and rice is tender. Remove from heat and let stand covered for 5 minutes. Fluff with a fork.
02 - While rice cooks, season shrimp with kosher salt and black pepper evenly.
03 - Heat olive oil in a large skillet over medium-high heat. Add minced garlic and sauté for 30 seconds until fragrant but not browned.
04 - Add shrimp in a single layer. Cook 2 minutes on one side until pink, then flip and cook 1 to 2 more minutes until just opaque.
05 - Add lemon zest, lemon juice, and red pepper flakes if using. Toss shrimp to coat evenly. Remove from heat and stir in chopped parsley.
06 - Serve shrimp over steamed rice. Garnish with lemon wedges and extra parsley if desired.
