  1. Melt the butter with the olive oil in a large pot over medium-low heat. Add the onion slices and garlic to the pot; season with a pinch of salt and black pepper. Cook the onions in the oil mixture until caramelized, stirring every 10 minutes to keep from browning too quickly, about 1 hour.
  2. Stir the brown sugar and thyme into the caramelized onions; allow the sugar to melt into the onion mixture, about 2 minutes. Pour the wine over the onions and bring to a boil while scraping the browned bits of food off of the bottom of the pan with a wooden spoon; continue simmering another 5 minutes. Add the beef stock; cook together another 10 minutes. Season to taste with more salt and pepper, if desired.
  3. Preheat the oven's broiler.
  4. Ladle the soup into 5 oven-safe crocks arranged onto a baking sheet. Top the soup with a slice of French bread; cover with a slice of Swiss cheese and sprinkle with some of the Parmagiano-Reggiano cheese.
  5. Melt the cheese under the broiler until browned, 2 to 3 minutes.

I loved this - the onions melted in your mouth! It was a little sweet for my fiance's taste, but I think we'll just try it with a chardonnay next time to see what a difference that makes.

This soup was so good. The port wine & thyme added a delicious unique flavor. Really enjoyed it!

This was a good soup but I prefer one with a richer flavor, not so sweet, and more depth. I will try again with the Chardonnay.

Thanks for the recipe post! I was trying to remember a similar recipe and didn’t know how much Port to add. This turned out excellent! I did make a few changes, I used yellow onions, did not ...

A very good soup, with lots of flavor. I used sherry wine in place of white wine.
