Difficulty Level
Medium – requires attention to detail but achievable for enthusiastic home cooks
Ingredients
- 200g foie gras, chilled and sliced into ½-inch medallions
- 1 baguette, sliced diagonally into ½-inch thick pieces
- 2 large sweet onions (such as Vidalia or walla Walla), thinly sliced
- 2 tbsp unsalted butter
- 1 tbsp olive oil
- 1 tbsp granulated sugar
- 2 tbsp balsamic vinegar
- Sea salt and freshly ground black pepper, to taste
- Fresh thyme leaves, for garnish
- Flaky sea salt, for finishing
Instructions
- prepare the crostini: Preheat your oven to 375°F (190°C). Arrange baguette slices on a baking sheet. Lightly brush each slice with olive oil,then bake for 8-10 minutes,flipping halfway,until golden and crisp. Set aside to cool.
- Caramelize the sweet onions: In a large skillet, melt the butter over medium heat. Add the thinly sliced sweet onions, stirring to coat. Sprinkle sugar over the onions and cook, stirring frequently, for about 15 minutes or until they become soft and golden brown. Avoid high heat to prevent burning.
- Deglaze and finish onions: Pour balsamic vinegar into the skillet, stirring to lift any caramelized bits.cook for another 3 minutes until the vinegar reduces and thickens slightly, creating a luscious glaze. Season with salt and pepper to taste. Remove from heat.
- Sear the foie gras: Using a dry non-stick skillet,heat over medium-high. Season foie gras slices lightly with salt and pepper. Sear each side for about 30 seconds until a golden crust forms but the center remains soft. Work quickly to avoid melting too much fat. Place seared foie gras on paper towels briefly to drain excess fat.
- Assemble the crostini: Layer a spoonful of warm caramelized onions on each crostini, then top with a slice of seared foie gras. Garnish with fresh thyme leaves and a pinch of flaky sea salt for an aromatic finish.
Chef’s Notes
- Onion Selection: Sweet onions like Vidalia or Walla Walla are crucial for their low sulfur content and natural sugars that caramelize beautifully without bitterness,perfectly complementing foie gras.
- Foie Gras Alternatives: If foie gras isn’t accessible,try substituting with duck or chicken liver pâté lightly warmed for a similar effect.
- Make-Ahead: Caramelized onions can be prepared 2 days in advance and refrigerated. Reheat gently before assembling for convenience.
- Seasoning: Avoid over-salting foie gras; its richness is enhanced by just a subtle touch of seasoning paired with the sweet onion glaze.
- Serving Temperature: Serve crostini warm or at room temperature for the best texture and flavor contrast.
