Step‑by‑Step Instructions for Instant Pot French Onion Soup
Step 1: Sauté the Onions
Set your Instant Pot to sauté mode and melt 4 tablespoons of butter. Add 4 cups of thinly sliced yellow onions and sauté for about 15 minutes, stirring occasionally, until the onions are golden brown and caramelized. The rich aroma will fill your kitchen, signaling that you’re on the right track to making a delicious Instant Pot French Onion Soup.
Step 2: Season and Thicken
Sprinkle in 1 teaspoon of salt, ½ teaspoon of pepper, 1 tablespoon of dried thyme, and 1 tablespoon of flour. Stir the mixture thoroughly, ensuring the onions are well-coated with the seasonings. Keep sautéing for an additional 2 minutes. This step enhances the flavor profile and begins to thicken the base of your soup, setting the stage for its comforting richness.
Step 3: Add Wine for Flavor
Pour in ½ cup of red wine and allow it to sauté for another 1-2 minutes. Scrape any browned bits from the bottom of the pot to deglaze and incorporate the depth of flavor. As the liquid reduces, your Instant Pot French Onion Soup starts to transform, taking on a wonderfully complex taste that pairs beautifully with the sweet onions.
Step 4: Combine Broth and Pressure Cook
Add 4 cups of beef broth to the pot and stir gently. Secure the lid tightly, ensuring the steam release handle is set to the sealing position. Set the Instant Pot to high pressure for 5 minutes. As the pot pressurizes, which may take around 5-10 minutes, the delicious flavors meld together, creating an irresistible, hearty base.
Step 5: Quick Release and Prepare to Serve
Once the cooking time is up, carefully perform a quick release of the pressure. After it’s safe, open the lid and give the soup a good stir. Your Instant Pot French Onion Soup will be fragrant and bubbling, ready to be ladled into bowls.
Step 6: Broil with Toppings
Preheat your broiler. Ladle the soup into oven-safe ramekins or bowls and top each with a slice of crusty baguette and a generous sprinkle of Gruyere cheese. Broil for about 2-3 minutes until the cheese is melted and bubbly—keep a close eye to avoid burning.
Step 7: Serve and Enjoy
Remove the ramekins from the oven, allowing them to cool slightly. Serve the piping hot Instant Pot French Onion Soup immediately, reveling in the combination of gooey cheese, rich broth, and crunchy bread. Each bite encapsulates the warmth and comfort you’re craving!

Additionally, the soup itself can be cooked in advance and stored without toppings for up to 5 days in the fridge. To reheat, simply warm it on the stovetop or in your Instant Pot using the sauté function before topping with the baguette and cheese and broiling just before serving. By prepping ahead, you’ll ensure a quick, delicious meal that’s just as decadent and comforting!
How to Store and Freeze Instant Pot French Onion Soup

Instant Pot French Onion Soup Recipe FAQs

What if my soup is too thin?
If you find that your soup is thinner than you’d like after cooking, don’t worry! You can thicken it by mixing a cornstarch slurry. Just whisk together 1 tablespoon of cornstarch with 2 tablespoons of cold water, then stir this mixture into the hot soup. Cook on the sauté setting for another few minutes until it thickens to your desired consistency.
Are there any dietary considerations I should note?
Yes! If you’re catering to dietary restrictions, you can easily make this soup vegetarian by substituting beef broth with vegetable broth. Additionally, for a gluten-free version, simply omit the flour and use gluten-free baguette as a topping. Always check labels if allergies are a concern!
How can I enhance the flavor further?
For an extra depth of flavor, consider sautéing the onions a bit longer until they’re deeply caramelized and dark in color. This adds a robust, sweet flavor that takes the soup to the next level!
