Caramelized Onion & Brie Tartines

Print Recipe

Rustic open-faced tartines topped with sweet, deeply caramelized onions, melted creamy Brie, and a drizzle of balsamic glaze—an elegant yet easy ensemble perfect for casual gatherings or refined snacks.

Ingredients

Scale
  • 6 slices artisan baguette or country loaf
  • 2 large sweet onions (e.g., Vidalia or yellow), thinly sliced
  • 2 tablespoons unsalted butter or olive oil
  • 1/4 teaspoon salt
  • 1/4 teaspoon ground black pepper
  • 6 ounces Brie cheese, sliced
  • 2 tablespoons balsamic glaze or reduction
  • Optional: fresh thyme or rosemary
  • Optional: fig jam, honey, or fresh fig slices

Instructions

  1. In a skillet, melt butter or heat olive oil over medium-low heat. Add onions and a pinch of salt. Cook, stirring occasionally, until deep golden brown and sweet—about 25–30 minutes. Add a splash of water if onions dry out.
  2. While onions cook, preheat oven to 375 °F (190 °C). Arrange bread slices on a baking sheet and brush with olive oil. Toast for 5–7 minutes until golden around the edges.
  3. Top each toast slice with caramelized onions, then layer with Brie slices.
  4. Return tartines to oven for 5 minutes or broil 1–2 minutes until Brie is melted.
  5. Drizzle with balsamic glaze and sprinkle with thyme or rosemary, if using.
  6. Serve warm, optionally with fig jam or honey on the side.

Notes

  • Caramelized onions can be made up to 5 days ahead and refrigerated.
  • Use gluten-free bread for a gluten-free version.
  • Toast bread thoroughly to prevent sogginess.
  • Customize with fruit, nuts, or alternative cheeses.
