Caramelized Onion & Brie Toast on Sourdough


  • Author: Sofia Garcia

Description

A savory and melty caramelized onion & brie toast on sourdough – the perfect easy lunch idea with gourmet flair. Sweet, jammy onions and creamy Brie make this a cozy, satisfying meal.


Ingredients

Scale
  • 2 large slices sourdough bread (about 1-inch thick)
  • 1 large yellow onion, thinly sliced
  • 2 tablespoons (30 g) unsalted butter
  • 1 tablespoon (15 ml) olive oil
  • 1/2 teaspoon (2 g) sea salt
  • 1/2 teaspoon (2 g) sugar
  • 4 ounces (115 g) Brie cheese, sliced
  • Fresh thyme leaves (optional)
  • Freshly cracked black pepper

Instructions

  1. Preheat oven to 400°F (200°C).
  2. Peel and thinly slice the onion (about 1/8-inch thick).
  3. Heat butter and olive oil in a large skillet over medium-low heat. Add sliced onions, salt, and sugar. Stir to coat.
  4. Cook onions, stirring every couple of minutes, for 25-30 minutes until deeply golden and caramelized. If onions dry out, add a splash of water. Lower heat if browning too quickly.
  5. While onions cook, slice sourdough bread and lay on a baking sheet lined with parchment paper. Toast in the oven for 5-7 minutes until crisp but not hard.
  6. Slice the Brie cheese. If too soft, chill in the freezer for 5-10 minutes before slicing.
  7. Once onions are caramelized and bread is toasted, pile onions onto each slice of bread and top with sliced Brie.
  8. Return assembled toasts to the oven for 6-8 minutes, or until Brie is bubbly and just starting to brown.
  9. Remove from oven, sprinkle with fresh thyme leaves and cracked black pepper. Let cool for 1-2 minutes, slice, and serve warm.

Notes

For extra flavor, rub toasted bread with a cut clove of garlic before assembling. Add a drizzle of honey or balsamic glaze before serving for a sweet or tangy finish. Use day-old bread for extra crispiness. If onions brown too quickly, lower the heat and add a splash of water.
