Ingredients
  

  • 2 tablespoons olive oil
  • 4 tablespoons butter
  • 3 lbs sweet onion peeled and thinly sliced
  • 1 tablespoon Herbes de Provence
  • 1 cup good white wine I used a pinot grigio
  • 6 cups Vegetable Stock
  • 4 Pieces Sourdough Bread
  • 1/2 cup gruyere cheese grated, or mozzerella if you cannot find gruyere

Instructions
 

  • Set your Wolf Gourmet Multi-Function Cooker to the 'Sear/Sauté ' mode, then select 'Medium'. Add the butter and the sliced onions, and sauté for 30 to 45 minutes until the onions have caramelized to a deep brown. Sauté with the lid removed, and stir occasionally.
  • Once the onions have caramelized, add the wine directly into the pan, and stir with a wooden spoon, scraping and brown bits off the bottom of the pan.  Add the garlic, Herbs de Provence, and vegetable stock. Cover the pot, and switch the multi-cooker to Manual Mode. Select 'Medium' again, and slow cook for 2-3 hours until onions are soft and falling apart in the soup broth.  Taste, and add salt and pepper if desired.
  • Just before serving, slice your bread and place a heaping pinch of gruyere cheese on top. Place the bread and cheese under the broiler for 2-3 minutes until the cheese begins to brown and bubble.
  • Serve the hot soup with a cheese toast on top of the soup, or on a place next to the soup, and garnish with herbs.
