Ingredients

  • 1 tablespoon olive oil
  • 1 tablespoon butter
  • 1 12 lbs Spanish onions, peeled and sliced into thin strips (large)
  • 2 teaspoons fresh thyme, chopped (or 1/4 tsp dried)
  • robusto cheese, 2 cups, grated

Method

  • Add butter and olive oil to a saucepan just large enough to hold the onions, over medium heat.
  • When butter melts, add the onions, stir to combine and then cover the pan.
  • Reduce the the heat to med-low and cook, stirring occasionally until onions have wilted and given up their juices (about 30 minutes).
  • When the onion have wilted, add the thyme and pepper; stir to combine and continue to cook, covered, stirring occasionally until the onions have darkened to a deep golden brown (about 30 more minutes).
  • If there are any juices still in the pan, just uncover and raise the heat to medium and cook, stirring constantly for 1-2 minutes until most of the juices have evaporated.
  • Remove the onions and place in a bowl.
  • Allow to cool to room temperature.
  • When the onions have cooled, add the grated cheese and stir to combine (this onion/cheese mixture can be prepared up to one day in advance and stored tightly covered in the refrigerator.
  • When ready to serve, preheat oven to 375F.
  • Arrange the baguette pieces on a cookie sheet and divide the cheese/onion mixture on top of the bread, gently smoothing the topping over the bread.
  • Bake for about 8 minutes, until the crostini are bubbling and golden brown.
  • Serve hot or warm.
