Fettuccine tossed in a rich garlic Parmesan cream sauce with Cajun-seasoned shrimp and tender butter-poached lobster. It looks restaurant-fancy but comes together in about 40 minutes.
Cook the pasta. Bring a large pot of lightly salted water to a boil. Cook the fettuccine 8 to 10 minutes, until al dente, then drain.
Prep the lobster. With kitchen shears, cut down the top of each shell, remove the meat and cut it into bite-size chunks.
Poach the lobster. Bring the water to a gentle simmer in a small pan over medium-low heat. Whisk in the butter a piece at a time so it stays creamy, then add the lobster and poach gently for 5 to 6 minutes, until opaque. Do not let it boil. Keep warm.
Season the shrimp. In a large bowl, toss the shrimp with salt, pepper, Cajun seasoning and red pepper flakes.
Warm the shrimp. Heat the olive oil in a large skillet over medium-high heat. Add the shrimp and warm for 2 to 3 minutes, just until heated through. Transfer to a plate.
Make the sauce. Lower the heat to medium-low. Add the garlic and cook 30 seconds, until fragrant. Stir in the heavy cream and Parmesan and simmer 3 to 5 minutes, until thickened.
Finish. Stir in the parsley and herb butter, then taste and adjust the salt and pepper.
Toss and serve. Add the pasta and shrimp to the sauce and toss to coat. Top with the poached lobster and serve hot.
