Ingredients

Scale
  • 1 pound cooked lobster meat, chopped (claw and tail meat recommended)
  • 1 French baguette, sliced into 1/2-inch rounds (rustic or sourdough bread can also work)
  • 2 tablespoons olive oil (for brushing the bread before toasting)
  • 1 tablespoon fresh parsley, finely chopped (for garnish)
  • 1/2 cup mayonnaise
  • 1 tablespoon fresh lemon juice
  • 1 teaspoon lemon zest
  • 1 small garlic clove, minced
  • 1/2 teaspoon Dijon mustard
  • Salt and freshly ground black pepper, to taste

Instructions

  1. Preheat oven to 375°F (190°C). Arrange baguette slices on a baking sheet in a single layer. Lightly coat each slice with olive oil using a pastry brush.
  2. Toast bread in the oven for 8-10 minutes, flipping halfway through, until golden and crunchy. Watch carefully to avoid burning.
  3. While bread toasts, combine mayonnaise, fresh lemon juice, lemon zest, minced garlic, and Dijon mustard in a small bowl. Whisk until smooth and creamy. Season with salt and pepper to taste. Add water a teaspoon at a time if a thinner consistency is desired.
  4. If using uncooked lobster, steam or boil lobster tails until opaque (about 8-10 minutes). Let cool and chop into bite-sized chunks. If using pre-cooked lobster, chop and pat dry any excess moisture.
  5. Spread a generous dollop of lemon aioli onto each toasted baguette slice. Top with chunks of lobster meat.
  6. Garnish with chopped fresh parsley.
  7. Serve immediately to keep bread crisp. If preparing ahead, toast bread and make aioli in advance, then assemble just before serving.

Notes

Use fresh lemon juice for best flavor. Avoid overloading crostini to prevent sogginess. Toast bread until golden and flip halfway for even crispness. If lobster meat feels dry, toss gently with olive oil or lemon juice before topping. Lemon aioli can be made a few hours ahead and refrigerated. For dairy-free, use olive oil and mayo without butter. Variations include adding cayenne for heat, fresh herbs for flavor, or using gluten-free bread.
