Ingredients

6 medium onions sliced (peel and halve then and use your food processer...piece of cake!)
¼ cup butter
¼ cup all purpose flour
½ tsp. salt
¼ tsp. freshly ground black pepper
4 teaspoons fresh thyme
1 cup milk
1 cup chicken broth For vegetarian use vegetable broth
¼ cup white wine

For the Topping

¾ pound Italian Style Cheese (or use Gruyere or Swiss cheese), shredded
1 French bread baguette sliced into 1/2-inch rounds
¼ cup butter melted

For Garnish

2 teaspoons fresh thyme leaves optional

Instructions

In large oven proof skillet, sauté onions in 1/4 cup butter over medium heat, stirring frequently until onions are transparent, about 15 minutes.
Continue cooking until the moisture has evaporated and onions turn a light brown color. Add thyme and cook an additional 2 minutes. Remove the mixture from the pan into a bowl and set aside.
In the same skillet over low heat, melt remaining 4 Tbsp. butter. Whisk in flour and stir for 2 minutes. Add salt, pepper, milk and chicken broth, stirring constantly until thickened.
Stir in white wine and combine well.
Add onions back to the skillet and stir to combine the mixture well.
Sprinkle the top with shredded cheese.
Dip one side of bread slices in the 4 Tbsp. of melted butter. Place slices, buttered side up, over sauce, covering sauce completely. Bake at 350 degrees for 30 minutes or until bread is browned.
Garnish servings with fresh thyme leaves.

Notes

To Prepare in advance:

Prepare according to the recipe up to adding the shredded cheese on top and refrigerate until the next day. Remove from the refrigerator and put into a pre-heated 350 degree oven for 8 minutes.

Remove from the oven, top with the buttered bread slices and return to the oven for 30 more minutes.

Serve and garnish with thyme.
