01 - Bring a large pot of salted water to a boil. Cook the linguine according to package instructions until al dente. Reserve 1/2 cup pasta water, then drain and set aside.
02 - While the pasta cooks, heat 2 tbsp butter and the olive oil in a large skillet over medium-high heat.
03 - Season the scallops lightly with salt and pepper. Sear them in the hot skillet for 1–2 minutes per side until golden and just cooked through. Remove and set aside.
04 - Add the lobster pieces to the skillet, cooking for 2–3 minutes until opaque and just cooked. Remove and set aside with the scallops.
05 - Lower the heat to medium. Add the remaining 3 tbsp butter, garlic, shallot, and red pepper flakes (if using). Sauté for 1–2 minutes until fragrant but not browned.
06 - Pour in the white wine and let it simmer for 2–3 minutes until reduced by half.
07 - Add the lemon juice and zest. Return the scallops and lobster to the skillet. Toss gently to coat in the sauce.
08 - Add the drained linguine and some reserved pasta water as needed to create a glossy sauce. Toss in the chopped parsley and season with salt and pepper to taste.
09 - Serve immediately, garnished with extra parsley and lemon wedges.
