Preheat your smoker to 180f. Slice both stem and root ends off 8 sweet or yellow onions and remove peels. Place the onions directly on the grill grates and smoke at 180f for 60 minutes or until the onions start to soften and have a smoky aroma. Once smoked, remove onions from the smoker and slice them into rounds, or slice them from root to stem.
Melt ½ cup unsalted butter in a heavy-bottomed pot over medium-low heat. Add the onions and cook them down until browned and caramelized. Add 3 cloves garlic and sautee for another minute or two.
Use the 3 tablespoons sherry to deglaze the pan.
Add3 tablespoons all purpose flour and stir until thickened.
Add 8 cups smoked turkey stock or low sodium beef broth, 2 bay leaves and 3 sprigs fresh thyme.
Bring the soup to a simmer and simmer for 20 minutes.
Meanwhile, preheat the oven to 400f. Slice 1 baguette into 3/4 to 1" rounds and lay them in a single layer on a baking sheet.
Toast the rounds in the oven for 7-9 minutes or until golden brown.
Preheat oven on broil.
Ladle the soup into your french onion soup bowls.
Top the soup with a toasted baguette and a slice of provolone cheese.
Broil the soup on the top rack for approximately 2 minutes, or until the cheese is fully melted and a bit bubbly!
