Instructions

Preheat your oven to 375°F (190°C). Arrange the bread slices on a baking sheet and lightly brush with olive oil on both sides. Bake for 8–10 minutes, flipping halfway through, until golden and crisp. Set aside.
In a large skillet, heat butter and olive oil over medium heat. Add sliced onions, sugar, salt, and black pepper. Cook slowly for 25–30 minutes, stirring occasionally, until onions are deep golden brown and caramelized. Stir in balsamic vinegar during the last few minutes if using. Remove from heat and let cool slightly.
Spread softened goat cheese evenly over each toasted bread slice. Top with a spoonful of caramelized onions and sprinkle with fresh thyme leaves.
Arrange the crostini on a serving platter. Serve warm immediately or at room temperature. Optional: drizzle with a little olive oil or balsamic reduction before serving.

Notes

Use day-old bread for extra crispiness.
Caramelized onions can be made 2–3 days ahead and stored in the refrigerator.
Assemble crostini just before serving to maintain crisp texture.
Adjust sweetness of onions by modifying or omitting sugar.
Try variations with herbs like rosemary or sage, or add toasted nuts for extra texture.
