Preheat the oven to 425 degrees and line a baking sheet with parchment paper.
Working with one slice of sourdough at a time, cut it into four triangles. The easiest way to do this is to cut in an X pattern. Repeat until all four have been sliced, leaving you with 16 pieces.
4 slices sour dough bread
Lightly butter each piece and place on the baking sheet.
2 tablespoons butter
Bake in the oven for roughly 3-5 minutes or until lightly browned and crunchy.
Remove from the oven and allow to cool on a cool rack until easy to handle.
When cool enough to handle, either drizzle or brush balsamic evenly over all the pieces.
3 tablespoons balsamic vinegar
Spread an even amount of goat cheese onto all the slices. Each slice will get a little over 1 teaspoon.
4 ounces creamy goat cheese
Add half a slice of prosciutto to top of the goat cheese.
8 slices prosciutto
Top with a peach slice.
2 fresh peaches
Repeat this process until all the triangles are done.
Keep in the fridge until ready to serve.
Notes
Tips:
Keep the crostinis crunchy by waiting to assemble until no more than two hours before serving.
Elevate the peaches by grilling halved peaches for 2-3 minutes until the char marks appear. Then slice them afterwards.
Mix it up by adding arugula or microgreens for added freshness.
Transfer the toasted bread to a cooling rack to avoid them getting soggy while they cool down.
Ingredient Notes:
Sourdough – Other breads will work too, like a thinly sliced French baguette, ciabatta, homemade bread, or pre-toasted crostini.
Balsamic vinegar – If you don’t like the flavor of balsamic, you can omit it, but I love the acid combined with the peach flavor.
Prosciutto – this can be swapped out for another thinly sliced meat, ideally something salty like crispy bacon, pancetta, or ham. It can also be left off for a vegetarian option.
Goat cheese – for people who don’t like goat cheese, you can mix it up by doing a thin layer of cream cheese, mascarpone, ricotta, or burrata. I would avoid something with a really distinctive flavor like feta or brie.
Peach – fresh peaches only, don’t try to use frozen or canned for these. If you don’t have peaches, you could also make these with fresh blackberries, strawberries, or apricots.
