Ingredients

  • 36 crostini (see link below for how to make crostini)
  • 1 cup caramelized onions (one batch of recipe below)
  • 16 ounces brie cheese
  • dried thyme or dried rosemary
  • sea salt or kosher salt, optional

Instructions

  • Cook your crostini rounds as per recipe instructions through the link below if not done already. This can be done up to two days in advance and the crostini kept in an airtight bag or container.
  • While the bread is toasting, cook your caramelized onions if not done already. These can also be made in advance and kept in the refrigerator for up to two days.
  • Preheat oven to 400F.
  • Place the crostini on a silicone baking mat on a cookie sheet in a single layer.
  • Cut the brie into strips 1/8 inch wide. You can leave the rind on the brie (it is edible). Cut the brie strips down to just shorter than each piece of bread and place on top of the crostini.
  • Top each crostini with approximately 1/2 Tablespoon of the caramelized onions. Sprinkle with dried thyme or rosemary (if not in the onions already).
  • Place the crostini in the oven and cook just until the brie is starting to melt, approximately 7-10 minutes.
  • Remove from the oven and sprinkle with a sea salt or kosher salt if desired. Serve immediately.

Notes

You can use more or less of the brie and onions as desired or needed.  The exact diameter of your bread will vary and require different amounts of these ingredients.
