Instant Pot French Onion Soup
Instant Pot French Onion Soup—A quick and easy way to make a classic French onion soup recipe in a power pressure cooker. Delicious every time!
Servings: 4 servings
- Instant Pot
- 3 tablespoons unsalted butter
- 4 Large yellow onions — or Spanish onions halved and sliced 1/4 inch thick (about 2 1/2 pounds)
- 4 cloves garlic — minced about 2 teaspoons
- 2 springs fresh thyme
- 1 bay leaf
- 1/2 cup dry red wine — such as Cabernet Sauvignon
- 4 cartons Beef Bone Broth 8.25-ounce cartons
- 4 cups Beef Stock
- 3/4 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- 8 to 12 slices small baguette — cut about 3/4-inch thick
- 1/2 lb sliced provolone Gruyère cheese — white cheddar fontina, and gouda, are also delicious
- Turn the Instant Pot (or similar electric pressure cooker) to sauté. Add the butter and let melt. Once melted, add the onions, garlic, thyme, and bay leaf and stir to combine. Cook, stirring, until onions slightly soften and start to release liquid, about 5 minutes. Stir in 3 tablespoons water. Cover and seal the Instant Pot, then set to cook on HIGH pressure (manual setting) for 20 minutes. Release pressure to vent immediately.
- Remove the lid, then turn the Instant Pot back to sauté. Cook for 5 minutes until some of the liquid evaporates, then add the wine and bring to a simmer, scraping up any brown bits that have collected on the bottom of the pot. Let simmer for 10 minutes, until most of the wine has evaporated. Discard the thyme stems and bay leaf.
- Add the bone broth and stock. Bring to a simmer and let cook until the soup thickens, about 10 minutes. Add the salt and pepper, then taste and adjust the seasonings as needed.
- For the bread topping: When you’re ready to serve, preheat the oven broiler. Arrange the baguette slices on a baking sheet in a single layer. Sprinkle the slices with the Gruyère. Broil until bubbly and golden brown, 3 to 5 minutes, watching constantly towards the end so that the bread does not burn. Ladle the soup into bowls, then float the bread on top. Enjoy! Alternatively, if you have ovenproof bowls, you can ladle the soup into them first, top with each with a baguette slice and cheese, then arrange the bowls on a baking sheet and place the sheet under the boiler, until the bread is toasted and the cheese is melted.
