• Dried Thyme – Adds herbal notes to complement the onions.

Step‑by‑Step Instructions for Instant Pot French Onion Soup
Step 1: Sauté Onions
Begin by setting your Instant Pot to sauté mode. Add butter and once it has melted, toss in the sliced yellow onions. Sauté the onions for about 15 minutes, stirring frequently, until they become soft and start to turn a beautiful caramelized brown, filling your kitchen with an irresistible aroma.
Step 2: Season
Once your onions are perfectly caramelized, sprinkle in salt, pepper, dried thyme, and flour. Stir the mixture well, ensuring the onions are evenly coated with the seasoning. This step is vital as it enhances the flavors in your Instant Pot French Onion Soup, giving it a delightful depth.
Step 3: Add Wine
Now, pour in the red wine, allowing it to deglaze the pot. Sauté for an additional 1-2 minutes until the wine reduces slightly, creating a rich blend with the caramelized onions. Watch as the liquid bubbles up and smells divine, integrating beautifully into your soup base.
Step 4: Pressure Cook
Add the beef broth to your mixture, stirring to combine all ingredients. Make sure to secure the lid on your Instant Pot, setting it to cook on high pressure for 5 minutes. Keep in mind it will take about 5-10 minutes for the pot to come to pressure before cooking begins.
Step 5: Release Pressure
Once the cooking time is up, it’s time for a quick release. Carefully open the lid after the pressure gauge drops, taking caution not to burn your hands from the steam. The aroma of your Instant Pot French Onion Soup will be incredibly inviting, signaling that it’s ready for the next step.
Step 6: Prepare for Serving
As the soup cools slightly, take a moment to slice your baguette and grate the Gruyere cheese. These toppings will elevate your soup, providing that classic French onion experience. Prepare your broiler to get ready for that melty finish!
Step 7: Broil and Serve
Ladle the warm soup into oven-safe ramekins, placing slices of baguette on top, followed by a generous amount of grated cheese. Place the ramekins under the broiler for 2-3 minutes, watching closely until the cheese is bubbling and golden brown. Serve immediately and savor the cozy layers of your Instant Pot French Onion Soup!
Make Ahead Options
These Instant Pot French Onion Soup ingredients are fantastic for meal prep, allowing you to enjoy a gourmet experience even on your busiest nights! You can sauté the onions and combine them with the seasonings (up to 24 hours ahead) before pressure cooking. Just refrigerate this mixture in an airtight container overnight. When you’re ready to enjoy your soup, simply add the beef broth (or vegetable broth for a vegetarian version) and pressure cook for 5 minutes. Avoid adding the baguette and cheese until you’re ready to serve to keep them from getting soggy. With these prep steps, you’ll have a comforting bowl of soup that tastes just as delicious as if it were made fresh!

Instant Pot French Onion Soup Recipe FAQs
What type of onions should I use for the best flavor in my soup?
Absolutely! Using yellow onions is key; they bring out the natural sweetness when caramelized. If yellow onions are unavailable, white onions can be substituted, but they won’t have the same rich flavor profile.
How should I store leftover Instant Pot French Onion Soup, and how long will it last?
You can store leftover soup in an airtight container in the refrigerator for up to 1 week. To reheat, simply warm it on the stovetop or use the sauté mode in your Instant Pot for quick results. The more, the merrier – feel free to make extra for those cozy nights!
Can I freeze Instant Pot French Onion Soup, and if so, how?
Very! To freeze, ladle the cooled soup (without toppings) into individual portions in freezer-safe containers. It will stay good for up to 3 months. When you’re ready to enjoy it again, simply thaw in the refrigerator overnight and reheat on the stovetop. Refresh it by adding fresh baguette and cheese just before serving.
What if my soup turns out too thin?
No worries! If you find your soup isn’t as thick as you’d like, you can make a cornstarch slurry. Mix 1 tablespoon of cornstarch with 2 tablespoons of cold water until smooth. Stir this into the soup and let it sit with the lid on for a few minutes; it will naturally thicken as it steams. Trust me, this little trick works wonders!
Are there any dietary considerations I should keep in mind?
Absolutely! If you’re catering to dietary restrictions, you can easily make this recipe vegetarian by substituting beef broth with vegetable broth. Additionally, if someone has lactose intolerance, consider using plant-based cheese options like vegan mozzarella or nutritional yeast, which can mimic that cheesy flavor without the dairy.
How do I know if my onions are properly caramelized?
Very! You’ll want your onions to be soft, golden brown, and slightly sweet. The cooking process should take around 15 minutes, and they should glisten as they release their sugars. If they start to burn or stick too much, you might want to lower the heat slightly or add a splash of water to loosen them up. Happy cooking!
