1. Heat the olive oil in a large skillet over medium-high heat. Add the shrimp to the skillet, seasoning them with salt and pepper. Cook for 1-2 minutes on each side until they turn pink and opaque. Remove the shrimp from the skillet and set aside.
2. Reduce the heat to medium and add the butter to the skillet. Once melted, add the minced garlic. Sauté for about a minute until fragrant, being careful not to let the garlic burn.
3. Add the lemon juice, lemon zest, and red pepper flakes to the skillet, stirring to combine. Allow the mixture to simmer for about 2 minutes, letting the flavors meld together.
4. Return the shrimp to the skillet, tossing them gently to coat in the sauce. Cook for another minute until the shrimp are heated through.
5. Remove from heat and sprinkle with fresh parsley before serving.

Remember, the key to perfect shrimp is not to overcook them. They cook quickly, so keep an eye on them during the process.
