Time 35m

Yield 10 Cups

Number Of Ingredients 13

3 lbs yukon gold potatoes, scrubbed (unpeeled)
4 cups low sodium chicken broth
kosher salt & freshly ground black pepper
2 tablespoons olive oil
3 tablespoons unsalted butter, divided
3 large yellow onions, peeled and cut into 1/4-inch slices
6 ounces bacon, preferably slab, cut into 1/4-inch cubes
1 1/4 cups milk, plus additional as necessary
1/2 cup heavy cream
2 1/2 cups coarsely grated cheese, such as cheddar, gruyere
2 tablespoons coarsely chopped thyme leaves
finely chopped chives, for serving
sour cream, for serving

Steps:

  • Place potatoes, broth, and 1 tablespoon salt into Instant Pot. Close lid, set pressure to high, and cook 20 minutes. Allow Instant Pot to remain on warm setting.
  • Meanwhile, in a large skillet over medium-high heat, warm olive oil and 1 tablespoon butter until melted. Add onions, season generously with salt, and cook, stirring occasionally, until deeply golden and caramelized, about 25 minutes. If necessary, add 1-2 tablespoons water to skillet to prevent burning, scraping bottom of pan to incorporate caramelization. Adjust heat as necessary to prevent burning.
  • In a small skillet, cook bacon over medium heat, stirring occasionally, until crisp. Remove with a slotted spoon to a paper towel-lined plate.
  • If necessary, release pressure manually on Instant Pot. Using an immersion blender, blend potatoes and broth until nearly smooth. Add milk, cream, and remaining 2 tablespoons butter. Blend to combine. Fold in half of cheese, half of caramelized onions, and thyme. Season to taste with salt and pepper. If soup is too thick, thin to desired consistency with additional milk.
  • Serve, garnished with reserved cheese, reserved onions, chives, sour cream, and bacon.

Time 1h40m

Yield 4 serving(s)

Number Of Ingredients 14

1 tablespoon olive oil
1 lb red onion, thinly sliced (4 cups)
1 lb sweet onion, thinly sliced (4 cups)
1/4 teaspoon salt
1 cup mushroom
1 large garlic clove
2 tablespoons dry sherry
1 tablespoon balsamic vinegar
1 tablespoon Worcestershire sauce
4 cups beef broth
1 bay leaf
1/4 teaspoon fresh ground black pepper
2 unbaked 9-inch pie crust, room temperature
1 cup swiss cheese, grated

Steps:

  • Cut onions in half lengthwise and thinly slice into half moon shapes.
  • Pour olive oil into a large pot and heat to one notch over low. Add onions and sprinkle them with salt. Cover and let onions sweat for 15 minutes. Give onions a quick stir, cover and let sweat for another 15 minutes.
  • While onions are cooking, thinly slice your mushrooms, mince your garlic and preheat oven to 375°F.
  • Get 4 ovenproof bowls and place face-down on the pie crust. Cut 4 large circles out of pie crust, about 1" bigger than the size of your bowl. They do NOT have to be perfect circles - they look more rustic if the edges are jagged.
  • When onions are done sweating, uncover, turn heat to medium and brown slightly while stirring frequently for about 10 minutes. Add mushrooms, garlic, sherry, balsamic vinegar, Worcestershire sauce, beef broth, bay leaf, and black pepper. Bring to a boil, turn down to simmer for ½ hour or more.
  • Remove bay leaf. Pour soup evenly into bowls and cover each bowl with a crust. The crust should not be touching the soup. Poke 1 small hole in the middle of each crust. Bake for 12 minutes. Crust should be just golden.
  • Remove, and sprinkle each bowl evenly with Swiss cheese. Put back in the oven for about 3 minutes, until cheese has just melted.
  • Serve immediately and let your guests cut into the crunchy crust with their spoons and the cheese will melt into the soup.
