Before you start
Before beginning, ensure all ingredients are measured and ready. If using pre-steamed lobster, check for any stray shell fragments. Shred the gruyère cheese finely to ensure it melts evenly over the lobster mixture. Chop the fresh chives into small, uniform pieces.
Preheat your oven to 400°F (204°C) to ensure it reaches the correct temperature before you place the dish inside. Have your nori sheets prepared, either cut into squares or left as full sheets, and set aside the lemon zest and crispy garlic chips for the final garnish.

Instructions
Lobster Mixture Preparation
- Prepare the lobster mixtureIn a medium mixing bowl, combine the steamed lobster tail meat, black truffle Kewpie mayo, mascarpone, and chopped chives. Fold the ingredients together gently until the lobster is evenly coated in the creamy truffle mixture.Look for The mixture should appear thick, creamy, and well-combined with the lobster chunks evenly distributed throughout the bowl.Tip Ensure the lobster meat is well-drained before mixing to prevent a watery consistency in the final bake.
At the end of this phase, the lobster mixture should be thick, creamy, and aromatic. The truffle mayo should have fully coated the lobster chunks, and the chives should be evenly dispersed. Check that the mascarpone is thoroughly incorporated with no large lumps remaining.
The consistency should be spreadable but not runny, ensuring that it will hold its shape when layered over the seasoned sushi rice in the baking dish. If it feels too stiff, add a tiny bit more mayo to reach the desired texture.
Baking and Broiling
- Assemble and bakeSpread the seasoned sushi rice into the bottom of a ceramic baking dish. Top the rice with the lobster and truffle mixture, spreading it into an even layer. Sprinkle the shredded gruyère over the top. Bake at 400°F (204°C) for 10 minutes, then broil for 90 seconds until the cheese is bubbling and has developed a blistered, golden crust.Look for The cheese should be completely melted, bubbling vigorously, and displaying deep golden brown spots from the broiler.Safe temperature 145°F (63°C) internal temperature (shellfish)Tip Watch the broiler closely during the final 90 seconds to avoid burning the delicate gruyère crust.
Upon completion of the baking and broiling phase, the dish will be bubbling intensely and emitting a rich, savory aroma. The surface should be covered in a uniform layer of melted, blistered cheese with attractive golden-brown spots.
The edges of the rice should be warm, and the truffle lobster layer should be heated through. Ensure that the broiler has created a crisp texture on the cheese without burning it, providing a satisfying contrast to the creamy interior layer of the lobster mixture.
Final Garnish and Serving
- Finish and serveRemove the baking dish from the oven and let it rest for 5 minutes. Top the dish with fresh lemon zest and crispy garlic chips. Serve immediately with nori sheets, allowing guests to scoop portions into the seaweed wraps.Look for The dish should be fragrant, with the bright citrus notes of the lemon zest cutting through the rich, savory truffle and cheese flavors.Tip Keep the nori sheets in an airtight container until the moment of serving to ensure they remain perfectly crisp.
The final dish should look vibrant and inviting, with the bright yellow lemon zest providing a pop of color against the golden cheese. The crispy garlic chips should remain distinct and crunchy on the surface. When served, the aroma of fresh lemon and earthy truffle should be prominent. Check that the nori sheets are crisp and dry. Everything should be ready for immediate assembly, with the dish warm enough to be comforting but not so hot that it wilts the nori upon initial contact.
Common mistakes
A common mistake is over-baking the dish, which can cause the lobster meat to become tough and the truffle mayo to separate. Monitor the oven closely during the final broiling phase, as the cheese can go from perfectly golden to burnt in a matter of seconds.
Another mistake is failing to drain the lobster meat sufficiently; excess liquid will pool at the bottom of the dish, making the sushi rice soggy instead of light and fluffy. Always ensure the lobster is well-drained before folding it into the mayo mixture.
How to tell it’s done
The dish is considered done when the cheese on top has melted completely, is bubbling vigorously, and has developed a deep golden brown, blistered crust. Because the lobster is already cooked, the goal of the baking process is to heat the ingredients through and achieve the desired texture on the crust. The internal temperature of the lobster mixture should reach at least 145°F (63°C). Allow the dish to rest for 5 minutes after removing it from the oven to let the layers settle before serving.
- Shellfish: 145°F (63°C) in the thickest part
