Table of Contents

Make baked lobster mac and cheese by cooking lobster tails, making cheese sauce, combining with pasta, topping with breadcrumbs, and baking until golden.

Cold water lobster tails taste sweeter. Boil 8-10 minutes then ice bath. Remove meat and chop into bite-size pieces. Reserve juices for sauce.

Use small pasta shapes like elbows or shells. Cook al dente. Do not rinse. Starch helps sauce stick.

Make roux with butter and flour. Add warm milk slowly. Whisk constantly. Add gruyere, sharp cheddar, fontina, and parmesan gradually. Keep heat low. Add sour cream for tang.

Combine hot pasta, sauce, and lobster. Mix gently. Transfer to greased 9x13 dish. Top with panko breadcrumbs mixed with melted butter and parmesan.

Bake at 350°F for 30-35 minutes until golden brown and bubbling. Individual dishes take 20-25 minutes. Let rest 5 minutes before serving.

Never re-cook lobster meat. Add at final mixing stage. Overcooked lobster turns rubbery. Work fast while ingredients are hot.

Store refrigerated 3-4 days. Reheat in oven with splash of milk. Freezing works but sauce may break.
