Ingredients You'll Need:
- 3 tablespoons butter
- 4 large yellow onions, thinly sliced
- 1 teaspoon sugar
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon dried thyme
- 1/4 cup dry sherry (optional, but adds depth of flavor)
- 8 cups beef broth
- 2 bay leaves
- 1 teaspoon Worcestershire sauce
- 1 baguette, sliced
- 1 cup shredded Gruyère cheese (or Swiss cheese)
Step-by-Step Instructions:
-
Sauté the Onions (Manual Mode): Set your Instant Pot to the "Sauté" function. Add the butter and allow it to melt completely. Add the sliced onions, sugar, salt, and pepper. Cook, stirring occasionally, until the onions begin to soften, about 5-7 minutes. This initial sautéing step helps to develop the base flavors.
-
Pressure Cook the Onions: Pour in the sherry (if using) and thyme. Stir well to combine. Secure the Instant Pot lid and set the valve to "Sealing." Cook on high pressure for 10 minutes. Allow for a natural pressure release for 10 minutes, then carefully quick release any remaining pressure.
-
Simmer and Season: Stir in the beef broth, bay leaves, and Worcestershire sauce. Remove the lid and simmer for 5-10 minutes, allowing the flavors to meld. Taste and adjust seasonings as needed.
-
Assemble and Broil: Preheat your broiler. Ladle the soup into oven-safe bowls. Top each bowl with a slice of baguette and a generous amount of Gruyère cheese. Broil for 2-3 minutes, or until the cheese is melted and bubbly and slightly browned.
Frequently Asked Questions (FAQs)
Can I use other types of onions?
Yes, you can experiment with other types of onions, such as red onions or white onions. However, yellow onions are traditionally preferred for their sweetness and ability to caramelize beautifully. If using red onions, be aware that they will retain more of their color and sharpness.
What if I don't have sherry?
The sherry adds a nice depth of flavor, but it's not essential. You can omit it entirely, or substitute with a tablespoon of balsamic vinegar for a slightly different, yet still delicious, flavor profile.
Can I make this soup ahead of time?
Yes! This soup tastes even better the next day. Prepare the soup according to the instructions, but skip the broiling step. Store the soup in the refrigerator for up to 3 days. When ready to serve, reheat gently and top with cheese and baguette before broiling.
What kind of cheese is best for this soup?
Gruyère cheese is the classic choice for French onion soup due to its nutty and slightly sharp flavor, which complements the rich soup perfectly. However, Swiss cheese is a good substitute. Other melting cheeses, such as provolone or Fontina, can also be used.
How can I make this soup vegetarian?
To make this soup vegetarian, simply substitute the beef broth with a rich vegetable broth. Ensure your Worcestershire sauce is vegetarian-friendly as well, as some brands contain anchovies.
Tips for the Best Instant Pot French Onion Soup:
