Cook the linguine: Bring a large pot of salted water to a boil, and add 10 ounces of linguine pasta. Cook according to package instructions until al dente, usually around 8-10 minutes. Reserve ½ cup of pasta water before draining and set it aside.
Sauté the aromatics: In a large skillet, heat 3 tablespoons of unsalted butter over medium-high heat. Add 1 finely chopped shallot and sauté until translucent, about 2-3 minutes. Next, add 3 finely chopped garlic cloves, cooking for an additional 30 seconds until fragrant.
Add tomato paste: Stir in 2 tablespoons of tomato paste and cook for 1 minute. This helps to caramelize the paste, intensifying its flavor.
Create the sauce: Lower the heat and slowly incorporate 1 cup of heavy cream, stirring continuously. As the mixture warms, add in ½ cup of grated parmesan cheese until melted and smooth.
Season the sauce: Season the sauce with salt, pepper, 2 teaspoons of dried Italian seasonings, and 2 teaspoons of lemon zest. Mix well and taste, adjusting the seasoning as needed. If the sauce is too thick, add reserved pasta water a little at a time until desired consistency is achieved.
Combine the lobster and pasta: Gently fold in 12 ounces of cooked lobster meat and the drained linguine. Toss everything together until the pasta and lobster are well coated in the creamy sauce.
Garnish and serve: Plate the lobster pasta, garnishing with extra parmesan cheese, fresh basil leaves, and a sprinkle of red pepper flakes for a touch of heat. Serve warm and enjoy the luxurious flavors!
