Cook the rice: Rinse the rice under cold water until it runs mostly clear.
Add rice, water or broth, and a pinch of salt to a pot. Bring to a boil, then cover and reduce heat to low. Simmer 12–15 minutes until tender.
Rest off heat, covered, 10 minutes. Fluff with a fork.
Prep the shrimp: Pat shrimp dry with paper towels. Toss with salt, pepper, and smoked paprika.
Dry shrimp sear better and give you a nice, light crust.
Heat the pan: Set a large skillet over medium-high heat. Add olive oil and 1 tablespoon butter. When butter foams, add half the shrimp in a single layer.
Sear quickly: Cook shrimp 1–2 minutes per side until just opaque and lightly golden at the edges.
Transfer to a plate. Repeat with remaining shrimp.
Make the garlic butter sauce: Lower heat to medium. Add remaining 3 tablespoons butter.
When melted, stir in garlic and red pepper flakes. Cook 30–45 seconds until fragrant but not browned.
Finish with lemon: Add lemon zest and juice. Stir to emulsify into a glossy sauce.
Taste and adjust salt, pepper, or lemon.
Return shrimp to the pan: Toss shrimp in the sauce to coat. Warm through for 30–60 seconds. Sprinkle with parsley.
Assemble bowls: Spoon rice into bowls.
Top with shrimp and any extra sauce from the pan. Add green onions, veggies, avocado, and a squeeze of lemon. Finish with a pinch of salt and a dash of chili crisp if you like heat.
