01 - Bring a large pot of salted water to a rolling boil. Cook the linguine according to package directions until al dente. Reserve 1/2 cup of the pasta cooking water, then drain thoroughly and set aside.
02 - While the pasta cooks, heat 2 tbsp butter and the olive oil in a large skillet over medium-high heat until shimmering. Lightly season the scallops with salt and pepper. Sear for 1–2 minutes per side until golden brown and just cooked through. Transfer to a plate and set aside.
03 - Add the lobster pieces to the same skillet and cook for 2–3 minutes until the meat turns opaque and is just cooked through. Remove from the skillet and set aside with the scallops.
04 - Reduce the heat to medium. Add the remaining 3 tbsp butter, minced garlic, chopped shallot, and red pepper flakes. Sauté for 1–2 minutes until fragrant and softened, taking care not to brown the garlic.
05 - Pour in the white wine and let it simmer for 2–3 minutes until reduced by half, scraping up any browned bits from the bottom of the skillet.
06 - Add the lemon juice and zest to the skillet. Return the scallops and lobster to the pan and toss gently to coat in the sauce. Add the drained linguine, tossing to combine. Add reserved pasta water as needed to create a glossy sauce that clings to the pasta.
07 - Stir in the chopped parsley and season with additional salt and pepper to taste. Serve immediately in warmed bowls, garnished with extra parsley and fresh lemon wedges.
