Macaroni and cheese is already decadent, but with the addition of lobster, like in this recipe, it's given an extra dose of elegance.
In a large skillet, heat 1 tablespoon of oil over medium-high and sauté the onions and garlic until translucent, about 8 minutes. Deglaze the pan with sherry wine and reduce by half. Combine the water and lobster base and add to sauce. Add the cream and bring the sauce to a boil. Turn down to medium heat and simmer for 10 minutes. Add the gouda cheese and season with salt and pepper, to taste. Combine the cornstarch and water and add to sauce slowly in order to thicken. Place the macaroni in an oven safe bowl. Cover with sauce, top with lobster meat, and then Parmesan cheese. Bake in oven for 10-12 minute until crispy and brown on top.
