01 - Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Reserve 1/2 cup of pasta cooking water, then drain the pasta.
02 - Pat the shrimp dry and season lightly with salt and black pepper.
03 - In a large skillet, heat olive oil over medium-high heat. Add the shrimp and sauté for 2-3 minutes per side, until pink and just cooked through. Remove shrimp and set aside.
04 - In the same skillet, reduce heat to medium. Add garlic and red pepper flakes; cook for 1 minute until fragrant, being careful not to brown the garlic.
05 - Deglaze the skillet with white wine, scraping up any browned bits. Let it simmer for 2 minutes.
06 - Add lemon juice and zest, stirring to combine.
07 - Return the shrimp to the skillet, then add drained pasta. Toss everything together, adding a splash of reserved pasta water as needed to create a silky sauce.
08 - Stir in chopped parsley. Adjust seasoning with salt and black pepper to taste.
09 - Serve immediately, garnished with grated Parmesan and lemon wedges if desired.
