Guiness French Onion Soup

Compliments of my friend Eliz, this is the best French Onion soup I've tasted!

• Ready In: 3 hrs
• Serves: 4
• Yields: 4 bowls

Ingredients

• 10  sweet onions (like Vidalias) or 10  a combination of sweet and red onions
• 3  tablespoons butter
•  kosher salt
• 2  cups  Guinness stout
• 10  ounces beef broth
• 10  ounces chicken broth
• 10  ounces apple cider (unfiltered is best)
•  fresh thyme sprig, bay leaf and parsley
• 1  loaf  country bread
•  ground black pepper
• 1  cup  grated gruyere cheese

Directions

1. Trim the ends off each onion then slice from end to end. Remove peel and finely slice into half moon shapes. Set electric skillet to 300 degrees and add butter. Once butter has melted add a layer of onions and sprinkle with a little salt. Repeat layering onions and salt until all onions are in the skillet. Do not try stirring until onions have sweated down for 15 to 20 minutes. After that, stir occasionally until onions are dark mahogany and reduced to approximately 2 cups. This should take 45 minutes to 1 hour. Do not worry about burning.
2. Add enough beer to cover the onions and turn heat to high, reducing the beer to a syrup consistency. Add consume, chicken broth, apple cider and bouquet garni. Reduce heat and simmer 15 to 20 minutes.
3. Place oven rack in top 1/3 of oven and heat broiler.
4. Cut country bread in rounds large enough to fit mouth of oven safe soup crocks. Place the slices on a baking sheet and place under broiler for 1 minute.
5. Season soup mixture with salt and pepper. Ladle soup into crocks leaving one inch to the lip. Place bread round, toasted side down, on top of soup and top with grated cheese. Broil until cheese is bubbly and golden, 1 to 2 minutes.
