Ingredients
  • Caramelized Onions:
  • 2 tablespoons unsalted butter
  • 2 tablespoons olive oil
  • 3 medium yellow onions, halved and sliced ⅛-inch thick
  • 1 tablespoon balsamic vinegar
  • kosher salt
  • freshly ground black pepper
  • Green Herb Mayo:
  • 1 tablespoon capers, drained
  • ¼ cup fresh dill, tightly packed with stems removed
  • ¼ cup fresh parsley, packed with stems removed
  • 2 tablespoons fresh tarragon leaves
  • 1 cup good quality mayonnaise, preferably homemade
  • 1 tablespoon Dijon mustard
  • 2 garlic cloves
  • 1 tablespoon fresh lemon juice
  • ½ teaspoon kosher salt
  • freshly ground pepper to taste
  • Crostini:
  • 1 pound of bacon
  • 1 loaf rustic bread, sliced ½ inch thick
  • 6 tablespoons unsalted butter, softened
  • ½ cup frisée
  • 4 ounces parmesan, shaved (you can use a vegetable peeler for this)
Instructions
  1. To make the caramelized onions, melt 2 tablespoons of butter and olive oil in a large saute pan over medium heat. Add the onions and cook, stirring occasionally. Cook for 35 - 40 minutes until soft and caramelized. Add the balsamic vinegar and season with salt and pepper to taste. Toss and set aside.
  2. While the onions are caramelizing, make the Green Herb Mayo. Place the ingredients for the Green Herb Mayo into the bowl of a food processor. Pulse until smooth. Cover and refrigerate until ready to use.
  3. Add the bacon to a cold pan and heat over medium heat. Turning occasionally, cook to your desired crispiness. Once cooled, roughly chop and set aside.
  4. Heat a large saute pan over medium-low heat. Butter each side of the bread and toast until golden-brown, about 2-3 minutes per side.
  5. To assemble the crostini - spread the Green Herb Mayo on one side of the toast. Top with the caramelized onions, chopped bacon, frisée, and shaved parmesan. Serve and enjoy!
