Ingredients
  • 1 loaf Baguette

  • 2 null Yellow Onions
  • 2 tablespoons Olive Oil
  • 2 tablespoons Balsamic Glaze
  • 1 teaspoon Fresh Thyme

Caramelize the Onions

Slice the onions thinly. In a large skillet, heat the olive oil and butter over medium-low heat. Add the sliced onions and cook slowly, stirring occasionally, for about 20-25 minutes, or until they are softened and caramelized. Stir in the brown sugar during the last 5 minutes of cooking. Season with salt and pepper.

Prepare the Baguette

Preheat your oven to 375°F (190°C). Slice the baguette into ½-inch thick rounds. Brush both sides of each slice with olive oil. Arrange the slices in a single layer on a baking sheet. Bake for 8-10 minutes, or until lightly golden and crisp. Let cool slightly.

Assemble the Crostini

Once the baguette slices are cooled slightly, spread a generous amount of brie cheese on each slice. Top with a spoonful of the caramelized onions.

Bake the Crostini

Place the assembled crostini back on the baking sheet. Bake for 5-7 minutes, or until the brie is melted and slightly bubbly.

Finishing Touches

Remove the crostini from the oven and let them cool slightly. Drizzle with balsamic glaze. Garnish with fresh thyme leaves. Serve immediately or at room temperature.

FAQ

  • Can I use a different type of onion?

    While yellow onions are recommended for their sweetness, you can use red onions for a slightly sharper flavor. Shallots also work well.
  • Can I make the caramelized onions ahead of time?

    Yes, you can make the caramelized onions up to 2 days in advance. Store them in an airtight container in the refrigerator. Reheat gently before using.
  • What if I don't have balsamic glaze?

    You can make your own balsamic glaze by simmering balsamic vinegar in a saucepan over low heat until it reduces to a syrupy consistency. Alternatively, you can use a small amount of balsamic vinegar.
  • Can I add nuts to this recipe?

    Yes, toasted walnuts or pecans would be a delicious addition to these crostini. Sprinkle them on top before serving.
