Ingredients
- 1 pound elbow macaroni or cavatappi pasta

- 6 tablespoons unsalted butter
- 1/2 cup all-purpose flour
- 5 cups whole milk, warmed
- 2 cups sharp cheddar cheese, freshly grated
- 1 cup gruyere cheese, freshly grated
- 1/2 cup mascarpone cheese

Instructions

- Fold in the cooked pasta and lobster meat gently until well combined.
- Transfer the mixture to your prepared baking dish.

Recipe Notes
– For the best cheese sauce, always grate your cheese fresh. Pre-shredded cheese contains anti-caking agents that can make your sauce grainy.
– If you can’t find fresh lobster, high-quality frozen lobster meat works well too. Just make sure to thaw it completely and pat it dry before using.
– The pasta should be slightly undercooked when you drain it, as it will continue cooking in the oven.
– For extra richness, you can replace half the milk with heavy cream.
– This dish reheats well in the oven at 350°F (175°C) covered with foil until heated through.
– If the top browns too quickly while baking, cover with aluminum foil and continue cooking until heated through.
