  • 210g walnuts
  • 24 slices French or sourdough bread baguette
  • 2 tablespoons olive or vegetable oil
  • 2 medium sweet onions, thinly sliced
  • 1 teaspoon salt
  • 1 tablespoon packed brown sugar
  • 1 tablespoon balsamic vinegar
  • 1 package of goat cheese, softened to room temperature
  • 1 teaspoon chopped fresh thyme or oregano leaves


  • Let's make the walnut butter first.
    • Add your walnuts into the NutraMilk container.
    • Press on the Butter cycle and set it for about 5-6 minutes.
    • Press on Start.
    • Open the container lid.
    • If you wish, set it for an additional 1-2 minutes to make a creamier butter.
  • In a nonstick skillet, heat the oil over medium-high heat. Now it's time to stir in the onions.
  • Cook uncovered for 10 minutes, but don't forget to stir every 3 to 4 minutes.
  • Reduce the heat to medium-low. Stir in your salt, brown sugar as well as the vinegar.
  • Cook 30 to 35 minutes longer, and stir every about 5 minutes up until the onions are deep golden brown.
  • Let it then cool slightly.
  • Heat oven to around 160°C and then place the bread slices on ungreased cookie sheet.
  • Spray lightly with non-stick cooking spray and bake for about 6 to 9 minutes (or until crispy). You can also toast bread.
  • Assemble crostinis by placing a layer of walnut butter first, then 1 teaspoon caramelized onions and top with 1 rounded teaspoon of goat cheese.
  • Finally, sprinkle with some herbs.
