  1. Preheat the oven to 400˚F (200˚C).
  2. Wash the potatoes and pat them dry. Poke the potatoes in several places with a fork and place them on a baking sheet.
  3. Bake for 60-75 minutes, until the potatoes are fork-tender. Let rest until cool enough to handle.
  4. Slice the potatoes in half lengthwise and scoop the flesh into a large bowl, leaving about ¼-inch in the shell. Mash the potatoes with a potato masher or fork until smooth. Mix in some butter to taste and season with salt. Set the mashed potatoes and potato shells aside. Turn on the oven's broiler.
  5. In a Dutch oven, melt 4 tablespoons butter over medium heat. Add the onions and ¾ teaspoon salt. Cook, stirring occasionally, for 30-45 min, until onions caramelize to golden brown.
  6. Add the flour and cook for 3 minutes. Add the wine to deglaze the pot and bring to a boil. Allow the mixture to thicken. Add the thyme. Slowly pour in the warm broth and let the mixture boil uncovered for 10 minutes, or until it is reduced by half. Season with salt and pepper.
  7. Arrange the potato shells on a baking sheet. Ladle the onion soup into the potato shells and cover with the mashed potatoes. Sprinkle generously with the cheese.
  8. Broil, watching carefully, for 1-2 minutes, until the cheese melts and browns. Serve immediately.
  9. Enjoy!
