01 - Bring a large pot of salted water to a rolling boil. Add linguine and cook according to package directions until al dente. Reserve 1/4 cup of the pasta cooking water, then thoroughly drain the pasta.
02 - In a large skillet, heat the olive oil and 2 tablespoons of butter over medium-high heat. Add the minced garlic and crushed red pepper flakes (if using), sautéing for 30 seconds until fragrant.
03 - Add the peeled and deveined shrimp to the skillet in a single layer. Season with salt and freshly ground black pepper. Cook for 1 to 2 minutes per side until the shrimp turn pink and opaque. Transfer the cooked shrimp to a clean plate.
04 - Pour the dry white wine and fresh lemon juice into the hot skillet, scraping the bottom with a wooden spoon to loosen any browned bits. Bring to a simmer and cook for 2 to 3 minutes, allowing the sauce to slightly reduce.
05 - Return the cooked shrimp to the skillet. Stir in the lemon zest. Add the drained linguine, the remaining 1 tablespoon of butter, and half of the chopped fresh parsley. Toss all ingredients together until well combined, adding reserved pasta water as needed to achieve a silky sauce consistency.
06 - Immediately plate the shrimp scampi with linguine. Garnish with the remaining fresh parsley, grated Parmesan cheese (if desired), and fresh lemon wedges.
