01 - Bring a large pot of salted water to a rolling boil. Cook pasta until al dente according to package directions. Reserve 1/2 cup of the starchy pasta water before draining. Set aside.
02 - While the pasta is cooking, thoroughly pat the shrimp dry with paper towels. Season evenly with kosher salt and black pepper.
03 - In a large skillet set over medium-high heat, melt 2 tablespoons of butter with the olive oil. Arrange the seasoned shrimp in a single layer and cook for approximately 1-2 minutes per side, until they turn pink and opaque. Remove the cooked shrimp from the skillet and place them on a separate plate.
04 - Reduce the skillet's heat to medium. Add the remaining 2 tablespoons of butter. Introduce the minced garlic and optional red pepper flakes to the skillet and sauté for about 1 minute until fragrant, taking care to prevent the garlic from browning.
05 - Pour in the dry white wine or chicken broth to deglaze the pan, scraping up any flavorful browned bits from the bottom. Allow the liquid to simmer and reduce for 1-2 minutes.
06 - Add the lemon zest and fresh lemon juice to the skillet. Return the sautéed shrimp to the pan.
07 - Add the cooked pasta to the skillet. Toss to combine with the sauce, incorporating small amounts of the reserved pasta water as needed to achieve a glossy, cohesive sauce. Stir in the finely chopped fresh parsley, basil, and chives.
08 - Taste and adjust seasoning as necessary. Serve immediately, garnishing with optional Parmesan cheese, additional fresh herbs, lemon wedges, and freshly ground black pepper.
