Sourdough crostini is a simple recipe to use up stale or leftover sourdough bread - and it's perfect for using up excess sourdough baguettes.
Originating from Italy, crostini means "little toasts". It sounds so much better in Italian, right?
You just need olive oil, salt and leftover sourdough to make these gourmet treats that will be the hero of your next charcuterie board.
You'll need some leftover or stale sourdough baguettes or sourdough bread to make these simple sourdough crostini.

What Bread To Use For Sourdough Crostini?
Leftover baguettes make the best sourdough crostini because of their small size. They really do have the best shape when sliced on the diagonal.
In saying that, any type of leftover sourdough bread can be turned into crostini. Even flavored sourdough like Jalapeño Cheddar or even Coffee and Date Sourdough Bread!
The best thing about this recipe is that even if the sourdough is stale and hard, it will still make delicious crostini!

Here's how to make the best sourdough crostini:
- Preheat your oven to 350F/180C.
- Slice your sourdough baguette into even slices. I like to make them around 1 cm thick (around half an inch). Try to make them as even as you can.
- Arrange the slices on a baking tray lined with parchment paper.
- Brush each slice of baguette with some olive oil. Make sure each slice is really well coated.
- Sprinkle salt over all of the slices.You could add other herbs and spices at this point if you like - Italian seasoning, garlic granules, fresh rosemary - anything like this adds a lovely flavor.
- Place the crostini into the oven and bake for around 30 minutes or until each slice is crunchy and golden.
- Remove from the oven and allow to cool on a wire rack.

These sourdough crostini are so versatile. Honestly, they pair with so many things and in fact, they can take something so humble and elevate it to something sophisticated.
Here are some delicious ways to enjoy sourdough crostini:

- Serve as the perfect accompaniment to a hearty winter soup.
- Use them instead of crackers when you want to enjoy cheese.
- Serve them as part of a charcuterie board or cheese platter.
- Make them into fancy little canapè next time you need to take a plate to a party - top them with cream cheese, smoked salmon and little dill and voila!
- Make mini bruschetta - rub a little garlic on the baguette pieces when you brush on the olive oil and then top the crostini with slices of tomato, basil leaves and drizzle with olive oil!
How Long Do Sourdough Crostini Last?
If baked until crispy, sourdough crostini will last for a few weeks stored in an air tight container. I prefer to store these in a glass jar (if they even last that long) to ensure they stay crisp. They usually go a bit soft if stored in plastic.
If they do go a little soft, you can crisp them up in a warm oven.
