Cook the lobster ravioli according to package instructions. Drain and set aside, reserving a little pasta water.
In a large skillet over medium heat, melt the butter. Add the minced garlic and sauté for about 1 minute until fragrant, being careful not to burn it.
Stir in the lemon zest and lemon juice, then add the heavy cream. Bring the mixture to a gentle simmer, stirring frequently.
Season the sauce with salt and pepper to taste. If the sauce is too thick, add a splash of the reserved pasta water to reach your desired consistency.
Add the cooked lobster ravioli to the skillet, gently tossing to coat them in the sauce. Cook for an additional 1-2 minutes until heated through.
Remove from heat and stir in the chopped parsley. Serve immediately, topped with grated Parmesan cheese.
