  • 10 medium-sized yellow onions, sliced
  • 1/2 tsp each salt & pepper
  • 1/2 tsp dried thyme

How to Make the Recipe

Let’s walk through how to make this Instant Pot French Onion Soup step by step:

  1. Turn your Instant Pot to sauté mode. Add the butter and sauté the onions for 15 minutes, stirring occasionally, until they start to brown and caramelize. Don’t forget to scrape those delicious bits off the bottom of the pot!
  2. Add salt, pepper, thyme, and flour, stirring until the onions are well coated. Pour in the red wine and sauté for 1-2 minutes, letting some of the liquid reduce.
  3. Add the beef broth, then place the lid on your Instant Pot and make sure the valve is set to seal. Press the pressure cook button and set it to high for 5 minutes. The Instant Pot will take about 5-10 minutes to come to pressure, then it will cook for 5 minutes.
  4. Do a quick release of the pressure by flicking the switch at the top with a spoon. Open the lid when the pressure gauge has dropped and the lid opens easily. While the soup is cooking, slice your baguette, grate the cheese, and preheat your oven to broil on high.
  5. Ladle the soup into ramekins or oven-safe bowls. Top each bowl with a slice of baguette and sprinkle some Gruyère cheese over the top. Broil for 2-3 minutes, watching closely to make sure the cheese doesn’t burn. Remove from the oven and serve immediately!

Pro Tips for Making the Recipe

Here are a few tips to make your Instant Pot French Onion Soup even better:

  • Let the onions brown as much as possible in the first step—this is where the deep flavor comes from!
  • Don’t skip the red wine—it adds a rich, depth of flavor to the broth.
  • For an extra crispy top, toast the baguette slices in the oven for a few minutes before adding the cheese.

How to Serve

This French Onion Soup Recipe is perfect on its own, but you can also serve it with a side salad or crusty bread for a more filling meal. If you’re feeling fancy, add some fresh thyme or extra cheese on top for a beautiful presentation.

Make Ahead and Storage

You can make the soup base ahead of time and store it in the fridge for up to 3 days or freeze it for up to 3 months. However, it’s best to assemble the soup with the baguette and cheese just before serving for the crispiest results. Reheat the soup base, then top with fresh bread and cheese under the broiler.

There you have it—a delicious, easy-to-make Instant Pot French Onion Soup that’s ready in just 30 minutes! Perfect for quick family dinners or cozy nights at home. Let me know in the comments how you enjoy it!
