  • 4 large potatoes, cleaned and pricked with holes
  • 1 tablespoon canola oil
  • 2 teaspoons kosher salt


  • 3 tablespoons butter
  • 2 yellow onions, thinly sliced
  • 2 tablespoons flour
  • 1 cup beef broth
  • 1/2 teaspoon salt


  • 4 tablespoons salted butter
  • 1/2 cup provolone cheese, shredded
  • 1 cup Gruyere cheese, shredded and divided
  • 1/2 teaspoon salt



  1. Preheat the oven to 350° F.
  2. Wash each potato well, and prick holes all around the potato (carefully), using a knife or fork.

  3. Coat each potato with canola oil and kosher salt and place on a foil-lined cooking sheet. Bake for 1 hour or until potatoes are fork-tender.
  4. Remove from oven and let potatoes rest until they are cool enough to handle.


  1. While the potatoes are baking, melt the butter in a large skillet over medium-high heat.
  2. Add onions and cook until the onions are browned and tender (approximately 15-20 minutes).
  3. In a medium bowl, mix together beef broth and flour. Pour over cooked onions and stir until mixture comes to a boil. Set aside.


  1. Using a sharp knife, slice the top off of each potato (horizontally). You will not be using this part of the potato.

  2. Using a spoon, remove the center of each potato and place it into a large mixing bowl. Be very careful not to tear the potato skin of the hollowed out part of the potato. Lay the hollowed-out potato shells on a baking sheet.

  3. Add butter, provolone, and 1/2 cup of the gruyere cheese to the large bowl and mash with the spooned out potato until well mixed.

  4. Filled the hollowed-out potato skins with the cheese and potato filling.

  5. Top each potato with the onion mixture and the other half of the gruyere cheese. Bake for 15-20 minutes, or until the cheese is melted.
