Our Green Goddess Lobster Sandwich Recipe is a dressed-up version of a classic lobster roll. We toss perfectly cooked buttery lobster with a quick green goddess dressing studded with fresh tarragon, basil, and green onion. We pile it high on toasted sourdough bread and top it off with peppery arugula and a squeeze of lemon.
Use kitchen shears to cut each lobster shell down the middle, lengthwise. Use a large chef's knife to line up against where you cut and firmly cut down to split the shell in half lengthwise. Sprinkle the flesh with salt.
Heat a medium skillet to a medium heat. Add butter. Once butter has melted, add lobster, flesh-side down. Cook for 2-3 minutes, then flip. Continue to cook over a medium heat until shells turn bright red and start to curl, another 2-3 minutes. As you cook, spoon the butter over the flesh. Remove tails from heat. Let sit for a minute or two and then remove the meat from the shells. Cut into bite-sized pieces.
Meanwhile, make the dressing. To a mini food processor or blender, add mayo, lemon juice, salt, tarragon, basil (if using), green onions, and garlic clove. Blend until smooth. Season to taste with salt and pepper.
Once lobster has cooled, toss with 3 tablespoons of the dressing. Add more if desiried.
Spread remaining dressing on all pieces of sourdough. Top two pieces of the bread with a little bit of arugula followed by a few slices of tomato. Evenly divide lobster meat between two sandwiches. Top with other piece of bread. Serve!
