01 - Bring a large pot of generously salted water to a rolling boil. Add the linguine and cook according to package directions until it reaches an al dente texture. Before draining, reserve 1/4 cup of the pasta cooking water. Drain the linguine thoroughly.
02 - While the pasta cooks, heat the olive oil and 2 tablespoons of butter in a large skillet or sauté pan over medium-high heat. Add the minced garlic and crushed red pepper flakes (if using) and sauté for about 30 seconds, until fragrant, being careful not to burn the garlic.
03 - Add the prepared shrimp to the skillet in a single layer. Season the shrimp with salt and pepper. Cook for 1 to 2 minutes per side, until they turn pink and opaque. Once cooked, transfer the shrimp to a clean plate.
04 - Pour the dry white wine and fresh lemon juice into the same skillet, scraping up any browned bits from the bottom of the pan with a wooden spoon. Bring the liquid to a simmer and cook for 2 to 3 minutes, allowing it to reduce slightly and concentrate its flavors.
05 - Reduce the heat to low. Return the cooked shrimp to the skillet and add the lemon zest. Toss gently to ensure the shrimp are thoroughly coated in the sauce.
06 - Add the drained linguine, the remaining 1 tablespoon of butter, and half of the finely chopped fresh parsley to the skillet. Toss all the ingredients together to combine, adding the reserved pasta water incrementally as needed to create a luxurious, silky sauce that coats the pasta beautifully.
07 - Serve the Shrimp Scampi with Linguine immediately. Garnish with the remaining fresh parsley, grated Parmesan cheese (if desired), and fresh lemon wedges for a bright finish.
