Welcome to Soup-landia! The season of eating soups like tomato basil soup, Chinese noodle soup, and white bean and sausage soup. Just to name a few.
Whether you’re up to your rooftop in snow, or just enjoying the occasional cold front, nothing’s quite as comforting as a steaming bowl of soup on a chilly day!
Except for maybe a steaming bowl of soup with a couple of these golden, buttery, perfect crostini to dip into it!
You might be thinking, isn’t “crostini” just toasted bread with a fancy name?
Believe me, it’s not!
Stretching Your Soup with Homemade Crostini
Who doesn’t love soup? Curried butternut squash soup, slow cooker Mexican potato soup, and minestrone soup are among my family’s favorites.
But, even with a Caesar salad alongside it, soup can sometimes feel too light to be a complete meal… Enter these simple and delicious crostini!
This recipe for crostini will add a hearty finishing touch to nearly any soup, plus they’re easy, frugal, and ready in just minutes!
Here’s What You Need

- Loaf of sourdough bread (try my homemade recipe)
- Butter
Notes on Ingredients
1. Best bread for crostini
I love sourdough – not only for its nutritional benefits but also because its more airy texture makes for a wonderfully light and crispy crostini. Try my simple sourdough recipe if you’re looking for a good recipe.
Note: If sourdough scares you, this no-knead overnight artisan bread might be a good option!

2. Bread thickness
This is partly a matter of personal preference, and partly a matter of how you want to serve your crostini. For:
- A lighter, crispier texture – cut into thin slices (1/4-1/2″).
- Thicker crostini- like those used in French Onion Soup, or for Bruschetta, you’ll want them closer to 1″ thick.
How to Make Crostinis
Step 1. Preheat oven to 400F.
Step 2. Slice sourdough to desired thickness and place on parchment-lined baking sheet.

Step 3. Cook for 4 minutes, turn slices over and cook for another 4 minutes.
Step 4. Remove from oven, and turn the broiler on.

Step 5. While the broiler is heating, butter one side of each bread slice. After brushing all slices with butter, broil for 1-2 minutes, or until the edges just begin to darken.
Notes for the Best Crostini Recipe

Bread Crostini FAQs
Bruschetta is when the whole loaf or wide slices of sourdough bread or Italian are toasted. Crostini is sliced into thinner pieces and then toasted.
Crostini is crispy on the outside and easy to chew on the inside.

Hi Shelli,
Thanks for your comment, but this recipe for crostini is a method for making homemade crostini in the oven, rather than buying it from the store. Additionally, we always make homemade crostini using homemade bread (which the recipe is listed). Hope this helps!
Great Soup! Thanks for the recipe. Made it using this as a guide but I’m a cook who does it his way. lol Everyone loved it and ask when I gonna make some more. THANKS!
