Serves: 8 servings
Ingredients
- 1 baguette, sliced
- 2 large onions, thinly sliced
- 2 tbsp olive oil
- 1 tbsp balsamic vinegar
- Salt to taste
- Fresh thyme for garnish
Instructions
- Preheat your oven to 400°F (200°C). This will ensure that your crostini are perfectly toasted and crispy.
- Slice the baguette into 1/2-inch thick slices. Arrange the slices on a baking sheet in a single layer.
- Drizzle the baguette slices with a little olive oil, using a brush or your hands to ensure they are evenly coated. This will help them crisp up in the oven.
- Place the baking sheet in the preheated oven and toast the baguette slices for about 8-10 minutes, or until they are golden brown and crispy. Keep an eye on them to prevent burning.
- While the baguette slices are toasting, heat the remaining olive oil in a large skillet over medium heat.
- Add the thinly sliced onions to the skillet. Stir them to coat with the olive oil, then season with a pinch of salt to help draw out their moisture.
- Cook the onions, stirring occasionally, for about 15-20 minutes, or until they are soft, caramelized, and golden brown. If the onions start to stick to the pan, you can add a splash of water or a little more olive oil.
- Once the onions are caramelized, add the balsamic vinegar to the skillet. Stir well to combine and cook for an additional 2-3 minutes, allowing the vinegar to reduce slightly and coat the onions.
- Remove the skillet from heat and set aside the caramelized onions.
- Once the baguette slices are toasted, remove them from the oven and let them cool slightly.
- To assemble the crostini, place a generous spoonful of the caramelized onions on each toasted baguette slice.
- Garnish each crostini with a sprinkle of fresh thyme leaves for added flavor and a pop of color.
- Serve the caramelized onion crostini warm or at room temperature as a delicious vegan appetizer or snack.
Tips
- Patience is key when caramelizing onions - low and slow is the secret to achieving that deep, rich golden color and sweet flavor.
- Use a heavy-bottomed skillet to ensure even heat distribution and prevent burning.
- Don't rush the caramelization process; it typically takes 15-20 minutes to develop those complex, sweet flavors.
- For extra depth, you can add a tiny pinch of sugar to help the onions caramelize more evenly.
- Choose a fresh, high-quality baguette for the best texture and flavor.
- Watch your baguette slices carefully while toasting to prevent burning - they can go from golden to burnt quickly.
- Fresh thyme is ideal, but if unavailable, dried thyme can work as a substitute.
