  • 1 medium white onion sliced
  • 2 tablespoons butter salted
  • 7 tablespoons olive oil or 1/4 cup plus 3 tablespoons
  • 2 cloves of garlic minced
  • 1 teaspoon salt
  • 8 ounces mushrooms sliced
  • 1 baguette sliced
  • ½ cup crumbled goat cheese or soft goat cheese used as a spread.


  • Combine the onion, butter, and ¼ cup of the olive oil in a pan. Cook the onions over medium heat until soft and caramelized.
  • Once the onions have caramelized, add the minced garlic, salt, and mushrooms. Continue cooking the mushrooms over medium heat until they are sauteed.
  • Once sauteed, set the mushroom mixture aside and brush olive oil over the baguette slices.
  • Bake the bread for five minutes at 400 degrees Fahrenheit.
  • Top the bread with a spoonful of crumbled goat cheese (or spread with soft goat cheese) and mushrooms.
  • Serve and enjoy!


  • You can store the mushroom mixture in the fridge for up to 4 days. To reheat, give it a quick sauté in a non-stick pan until heated through.
  • Crostini can be made up to 3 days in advance and kept in an airtight container at room temperature.
