Caramelized Onion Crostini

I made this Tyler Florence caramelized onion crostini recipe as an appetizer for a friend’s smorgasbord birthday party, along with the caprese skewers. The combination of caramelized onions, salty anchovies, and Asiago with the tangy olive was amazing! These onion & olive crostini were a huge hit with everyone at the party, and they disappeared quickly.
Caramelized Onion Crostini
Ingredients:
- 2 tbsp butter
- 1 tbsp olive oil
- 2 onions, sliced
- 6 anchovy fillets, chopped
- 1 tsp thyme
- Sea salt and freshly cracked pepper, to taste
- 1 baguette, sliced
- â…“ cup pitted kalamata olives, sliced in half
- Asiago cheese, shaved

How to Make Caramelized Onion Crostini:
Heat the butter and olive oil in a large skillet over medium heat. Add the onions, anchovies, thyme, sea salt, and freshly cracked pepper to taste. Cook, stirring occasionally until the onions are sweet and golden brown, about 25-30 minutes.
Preheat the oven to 400 degrees.
Meanwhile, slice the baguette, then brush each slice with a bit of olive oil and place on a baking sheet.
Place the baking sheet in the oven and bake for 5-7 minutes, or until golden brown.
Top each baguette slice with a bit of caramelized onions, some shaved Asiago, and an olive. Enjoy.
