Cook the Pasta: In a large pot, bring salted water to a boil and cook the pasta according to the package instructions until al dente. Drain the pasta, reserving 1/2 cup of pasta water for later.
- Prepare the Lobster: If the lobster tails are not already cooked, use kitchen shears to cut along the top of the shell and remove the meat. Cut the lobster into bite-sized pieces and set aside.
- Make the Sauce: In a large skillet, heat olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant. If using, deglaze the skillet with white wine and cook for another 1-2 minutes, letting the wine reduce slightly.
- Add Cream and Cheese: Lower the heat and pour in the heavy cream. Stir in the Parmesan cheese, lemon juice, and lemon zest. Season with salt and pepper to taste. Let the sauce simmer for about 3-4 minutes, or until it thickens to your desired consistency. If the sauce gets too thick, add a bit of the reserved pasta water to loosen it up.
- Combine Pasta and Lobster: Add the cooked pasta and lobster meat to the skillet. Toss everything together until well coated in the sauce. If the sauce needs thinning, add a little more pasta water.
- Finish the Dish: Stir in the butter for extra richness, then adjust seasoning with salt, pepper, or more lemon juice if desired. Garnish with fresh parsley and red pepper flakes (if using).
- Serve: Serve immediately with extra Parmesan on the side for sprinkling.
