How to Make Instant Pot French Onion Soup
Sauté the Base: Set your Instant Pot to the sauté mode and melt the unsalted butter. Add the sliced yellow onions, garlic, fresh thyme, and bay leaf. Stir for about 5 minutes until the onions soften and start to caramelize, releasing their lovely aroma.
Deglaze the Pot: Pour in 3 tablespoons of water, scraping the bottom of the pot to lift any browned bits. This step is key to enhancing those delightful flavors!
Pressure Cook: Secure the lid on the Instant Pot. Cook on high pressure for 20 minutes and then perform a quick release to release the pressure—carefully, of course!
Further Sauté: Once safe to do so, return the pot to sauté mode. Allow the onion mixture to cook for an additional 5 minutes; this helps deepen the flavor even more.
Add Wine: Pour in the dry red wine and let it simmer for 10 minutes. This step allows the alcohol to evaporate and infuses the soup with a rich complexity.
Add Broths: Remove the bay leaf and thyme stems. Pour in the beef bone broth and beef stock, and let it simmer for another 10 minutes to marry all those lovely flavors together.
Season: Taste the soup and adjust the seasoning with kosher salt and ground black pepper as desired. This is your moment to make it just right!
Prepare Cheese Toasts: Preheat your oven’s broiler. Toast the baguette slices on both sides until golden and crispy, then top generously with grated Gruyère cheese. Broil until melted and bubbly, keeping a close eye to avoid burning!
Serve: Ladle the steaming soup into bowls, topping each with your warm cheese toasts. Dig in right away and revel in the cozy goodness!
Optional: Garnish with extra thyme leaves for a pop of freshness.

Instant Pot French Onion Soup Recipe FAQs
What type of onions should I use for the soup?
Absolutely! Yellow onions are ideal for this Instant Pot French Onion Soup because they provide the perfect balance of sweetness and flavor. Spanish onions can also be used as a substitute if yellow onions aren’t available, but it’s best to avoid white onions, as they tend to have a sharper taste and may not deliver the same comforting sweetness.
How long can I store the soup in the fridge?
You can store your homemade French Onion Soup in an airtight container in the refrigerator for up to 4 days. In fact, many people find that the flavors meld and deepen overnight, making it even more delicious the next day. Just make sure it’s completely cooled before sealing it up!
Can I freeze Instant Pot French Onion Soup?
Yes! To freeze, let the soup cool completely, then portion it into freezer-safe containers, leaving a little room at the top for expansion. This soup can be frozen for up to 3 months. When ready to enjoy, simply thaw overnight in the fridge and reheat gently on the stove or microwave.
What can I do if my onions don’t caramelize properly?
Oh no, don’t worry! If your onions aren’t caramelizing as they should, make sure to cook them patiently on the sauté setting, allowing them to soften and develop that lovely golden color. If they’re still sticking, you can add a splash of water or broth to help deglaze the pan and lift those flavorful browned bits. Alternatively, make sure you’re using enough butter to prevent them from burning.
Are there any allergy considerations I should be aware of?
Yes! If you’re cooking for someone with allergies, be mindful of the ingredients. This soup contains dairy from the butter and Gruyère cheese, while the broth may not be suitable for those with beef allergies. For a dairy-free or vegetarian option, you can substitute the butter with olive oil and use vegetable broth or mushroom broth instead of beef broth. Always check labels to ensure no hidden allergens in packaged ingredients.
How should I reheat leftovers for the best results?
To reheat your Instant Pot French Onion Soup, gently warm it on the stove over low heat, stirring occasionally to ensure even heating. For the ultimate experience, broil fresh cheese toasts just before you serve. This will give you that glorious, bubbly cheese layer that enhances each delicious spoonful. Enjoy that warmth and flavor all over again!
