French Onion Soup Casserole

Step 1: Heat butter and oil in a large skillet over medium high heat. Add in onions, garlic and 1 1/2 teaspoon salt. Cook, stirring frequently until onions become caramelized (this will take a while, about 30-40 minutes, if onions start to stick to pan, just stir a tbsp or two of the broth as needed).

Step 2: Once onions are caramelized, add in the broth, wine, Worcestershire sauce, paprika, pepper and thyme. Simmer over medium heat for 20 minutes, stirring occasionally.

Step 3: Turn heat to low and add in vinegar and season with additional salt and pepper if desired.

Step 4: Cover and keep over low heat to stay hot while you prepare the bread.

Step 5: Preheat oven broiler. Slice about 1/3 of a loaf of French baguette into about 12 slices.

Step 6: Spray a baking sheet with nonfat cooking spray, and arrange baguette slices evenly on sheet.

Step 7: Lightly mist again with an olive oil mister or the nonfat cooking spray and then place in oven for 3 minutes on each side, or until bread is well toasted on both sides.

Step 8: Remove bread from oven and set it to bake on 375 degrees.

Step 9: Pour onion mixture into an 9x9 inch greased casserole dish.

Step 10: Top evenly with bread slices and then cover evenly with Swiss cheese slices.
