Is Crostini French Or Italian?
Crostini or Crostino, for a single slice, is originally an Italian appetizer. It is made with small slices of grilled or toasted bread with one or more toppings.
These toppings can include:
- Cheese
- Meat
- Vegetables
You can also serve them with olive oil, herbs, or sauce.
What Is The Difference Between Crostini And Bruschetta?
The main difference between bruschetta and crostini is the size of the slice.
Bruschetta is made with a whole, wide slice of rustic Italian bread like focaccia or no-knead bread.
Crostini are made from a smaller type of bread like a baguette. You can serve them with a similar kind of topping although bruschetta is more commonly made with vegetables like roasted tomatoes.
