Ingredients

Sourdough Crostini

Whipped Feta Cheese Spread

  • 226 grams feta cheese 8 ounces
  • 114 grams cream cheese, softened 4 ounces

Carmelized Onions

  • 2 small Vidalia or yellow onions, thinly sliced
  • 20 grams olive oil 2 Tablespoons
  • 28 grams unsalted butter 2 Tablespoons
  • salt to taste

Toppings

  • jar of fig jam
  • fresh thyme

Instructions

  1. Traditional crostini's are made with slices of French baguette. You could create this easy appetizer with slices of sourdough baguette, but I most often opt for a loaf of sourdough artisan bread that has been baked as a batard (long form). You can use fresh bread or slightly stale sourdough bread.

Sourdough Crostini

  1. Preheat oven to 350 degrees F.
  2. With a serrated knife, slice a loaf of sourdough bread in half, then place the crumb facing down on the cutting board. This makes for easier slicing.

  3. Slice the half of the loaf into 1/3 inch slices and place the smaller pieces of bread on a rimmed baking sheet. You will most likely have to work in batches.
  4. Brush olive oil on each side the slices of bread bread and sprinkle with salt to taste.

  5. Bake the sourdough crostini for 16 minutes, flipping each slice half way through, or until golden brown and crispy.
    You want the bread to be toasted and crunchy, but not too hard that you could break a tooth! Remember the bread will crisp up as it cools.
  6. While the bread is baking, prepare the toppings.

Whipped Feta Cheese Spread

  1. In a food processor, combine the feta cheese and room temperature cream cheese. Mix the cheeses on high for 30 seconds, or until thoroughly combined. Using a rubber spatula, scoop the cheese into a small bowl and set aside.
    This can be down with an immersion blender, as well.

Caramelized Onions

  1. Next, add the unsalted butter and olive oil to a pan over medium heat.

  2. While the pan is preheating, thinly slice the onions. Once the butter is melted, add the onions.

  3. Cook until the onions start to turn light brown (about 5 minutes), stirring frequently. Then, turn the heat to low, cover with a lid and continue to cook for 15 minutes, stirring occasionally.
    Add a splash of water if the onions start to stick to the bottom of the pan or turning too dark.
  4. Once cooked, season with salt, stir and then remove the onions from the heat.

Assemble

  1. Spread the whipped feta cheese first to cover the sourdough crostini, then a scoop of fig jam, and finally a small layer on the caramelized onions. Top with a sprig of fresh thyme, if desired. Serve immediately and enjoy!

Notes

Ingredients & Substitutions

  • Loaf of Sourdough Bread - Traditional crostini's are made with slices of French baguette. You could create this easy appetizer with slices of sourdough baguette, but I most often opt for a loaf of sourdough artisan bread that has been baked as a batard (long form). You can use fresh bread or slightly stale sourdough bread.
  • Feta Cheese - Crumbled or in a block with work for this recipe.
  • Cream Cheese - For easy mixing, use room temperature cream cheese.
  • Fig Jam -  I love the sweetness from the fig jam, it compliments perfectly with the saltiness from the whipped feta and caramelized onions. However, if you aren’t a fan of figs, you could opt for apricot jam or pear preserves or even cherry jam for a pop of tartness!
  • Onions - Yellow onions and Vidalia (sweet onions) are my top choices for caramelized onions. They both contain a higher natural sugar content, leading to a delicious final product. You can use red or white onions, but they won’t produce as sweet and appealing final coloring. 
  • Thyme - Lemon thyme brought just a touch of brightness to this sweet and savory sourdough appetizer.

Other Toppings

Though I love the sweet and savory flavors of feta, fig, and caramelized onions, crostini toppings are endless! 
You can create a whole different appetizer experience just with a few good quality ingredients on top of this homemade crostini.
Some ideas include a classic favorite like bruschetta made with fresh tomatoes, fresh basil, olive oil and balsamic vinegar. Or you could create a more unique savory options with soft cheeses, like creamy ricotta, more fresh herbs, even slices of thin meats, and don't forget an extra drizzle of olive oil!
Like I said, the options are endless!
