5 from 1 reviews

French Onion Baked Potatoes are cheesy and loaded with lots of caramelized onions. They're a fun variation on twice baked potatoes and French Onion soup - scoop out the flesh of baked potatoes and mix with caramelized onions, load back in the potato skins, and top with extra onions and shredded cheese. 

Ingredients

  • 4 large russet potatoes, scrubbed clean
  • 1 tablespoon olive oil
  • Kosher salt and pepper
  • 1/4 cup unsalted butter
  • 4 medium-large yellow onions, halved and thinly sliced
  • 1 teaspoon dried thyme, or fresh
  • 1/2 cup sherry wine or white wine
  • 1 cup beef broth
  • 1 teaspoon Worcestershire
  • 1.5-2 cups shredded Gruyere cheese

Instructions

  1. Bake Potatoes - Preheat the oven to 400 degrees F. Take the scrubbed and dried russet potatoes and pierce them a few times with a fork then rub them with the oil and sprinkle with salt/pepper. Place on a baking sheet. Bake in the preheated oven for 50-60 minutes (depending on potato size). The potatoes should be tender - a knife should be able to easily pierce them.
  2. Caramelize Onions - Heat up a large pan over medium heat and melt the butter. Add the sliced onions and cook, while stirring occasionally so they don't stick or burn, until they are soft and caramel colored. This can take around 30 minutes.
  3. Add French Onion Ingredients - Add the thyme, wine, broth, and Worcestershire sauce to the onions. Scrape any stuck bits from the bottom of the pan. Stir to combine and bring the onions to a low boil/simmer and cook for about 5 minutes until most of the liquid is absorbed.
  4. Prep Potatoes - Cut top third off of each potato. Scrape the flesh of the potatoes into a bowl and place the potato skins back on the baking sheet.
  5. Mix Filling - Mash up the potato flesh in the bowl and mix in about half of the caramelized onions and 1 cup of the shredded cheese.
  6. Fill Potatoes - Scoop the filling into the potato skins and top each potato with extra onions and a sprinkle of shredded cheese.
  7. Bake -  Bake the potatoes (in the 400 degree F preheated oven) for about 5 minutes, or until the cheese is melted. You can also set the broiler to high for just a minute or so if you want more browning.

Notes

Leftovers can be stored in the fridge for up to 4 days. The caramelized onion mixture can be prepped 2-3 days in advance to save prep time day of.
