  • Brie Cheese: Opt for creamy brie that melts beautifully; choose one with a nice rind for added flavor.

  • Onions: Yellow onions work best due to their natural sweetness; slice them thinly for even caramelization.

  • Olive Oil: Use quality extra virgin olive oil to enhance flavor while sautéing the onions.

  • Balsamic Vinegar: A splash adds depth and balances the sweetness of the caramelized onions perfectly.

Recipe preparation for Caramelized Onion & Brie Crostini

How to Make Caramelized Onion & Brie Crostini

Prepare the Baguette: Preheat your oven to 400°F (200°C). Slice the baguette into 1/2-inch thick pieces and arrange them on a baking sheet.

Toast the Bread: Drizzle olive oil over each slice, then bake until golden brown and crispy, about 10 minutes. Keep an eye on them—they can go from golden to burnt in seconds.

Carmelize the Onions: Heat olive oil in a skillet over medium heat. Add sliced onions and cook slowly until they become soft and caramel-colored, about 20-25 minutes. Stir occasionally for even cooking.

Add Flavor with Balsamic Vinegar: Once onions are golden brown, add balsamic vinegar and fresh thyme. Cook for an additional 5 minutes until everything is well combined and aromatic.

Assemble the Crostini: Place generous spoonfuls of caramelized onions on each toasted baguette slice. Top with slices of brie cheese that will melt beautifully when baked.

Bake Until Gooey: Return the assembled crostini to the oven and bake until the brie melts and bubbles slightly, about 5-7 minutes. The aroma will have everyone flocking to the kitchen!

Enjoy this dish as an elegant appetizer or a cozy snack while you binge-watch your favorite series—either way, it’s sure to impress!

Perfecting the Cooking Process
