Ingredients

Instructions

  1. Parboil the Lobster

    Boil the lobster tail halfway — just until the shell turns red but the meat remains slightly translucent.
    Tip: Not sure about the exact time? Ask MrsT: “How long to boil 1 lb of lobster tail halfway done only?”

  1. Cool and Prepare the Lobster

    Transfer the lobster immediately into an ice bath to stop the cooking process. Once cooled, cut the tail in half lengthwise to expose the meat. Remove the meat, chop into bite-sized pieces, and set aside.

  1. Make the Lobster Broth

    In a pot, melt 1 tablespoon of butter. Add the lobster shells, shallot, and crushed garlic. Pour in pasta water and simmer for about 10 minutes to extract all the flavor.
    Strain and set aside the golden lobster broth — this will be your flavor-packed base.

  1. Prepare the Cheese Blend

    Shred your choice of cheeses and mix them together in a bowl. Reserve about ⅔ cup for topping later.
    Tip: Combining sharp cheddar with gruyere gives bold flavor, while mozzarella adds creamy stretch.

  1. Build the Cheese Sauce

    In a large pot, melt the remaining butter and sauté chopped shallot and garlic until fragrant. Add paprika, then sprinkle in the flour and whisk continuously to create a smooth roux.
    Gradually pour in the lobster broth, about half a cup at a time, whisking until you reach a thick, creamy consistency. Then add milk, onion powder, and cracked black pepper.
    Start adding shredded cheese, one handful at a time, stirring until fully melted and smooth.

  1. Combine Pasta and Lobster

    Add the cooked pasta to the cheese sauce and mix thoroughly until coated. Fold in the chopped lobster pieces. Adjust seasoning as needed.

  1. Bake to Perfection

    Transfer the mixture to a baking dish. Sprinkle the reserved cheese evenly on top (add breadcrumbs if you like extra crunch).
    Bake at 375°F (190°C) for 20–25 minutes, then broil for 3 minutes to achieve a golden, bubbly crust.

  1. Serve and Enjoy

    Let it rest for a few minutes before serving. Pair with a crisp white wine or sparkling water with lemon for a perfect balance.

Note

Pro Tips

  • Half-cook the lobster: Fully cooking it before baking makes it rubbery — partial boil keeps it tender.
  • Flavor boost: Use lobster shells to create broth — it adds restaurant-level depth.
  • Cheese control: Use high-quality blocks and shred them yourself for a smoother melt (pre-shredded cheese often contains anti-caking agents).
  • Texture balance: Mozzarella makes it extra gooey, while cheddar and gruyere provide flavor punch.
  • Make-ahead: Assemble up to the baking stage, refrigerate overnight, then bake fresh the next day.
