Step‑by‑Step Instructions for Instant Pot French Onion Soup

Step 1: Sauté Onions
Start by setting your Instant Pot to sauté mode. Melt 4 tablespoons of butter in the pot and add the 10 sliced yellow onions. Stir occasionally for about 15 minutes, allowing them to caramelize beautifully until they start to brown. Keep an eye on them to prevent sticking, scraping the bottom of the pot if needed.

Step 2: Season Onions
Once the onions are caramelized, sprinkle in 1/2 teaspoon each of salt and pepper, along with 1/2 teaspoon of dried thyme and 2 tablespoons of flour. Stir well to combine everything so the flour fully coats the onions. This will deepen the flavor of your Instant Pot French Onion Soup and create a lovely, thick consistency.

Step 3: Add Wine
Pour in 1/2 cup of red wine, stirring gently for about 1-2 minutes. This step helps to deglaze the pot, loosening any flavorful bits stuck to the bottom from the onions. Allow the wine to reduce slightly, which will enhance the depth of your broth and add a rich flavor profile to your soup.

Step 4: Pressure Cook
Next, add 6 cups of beef broth to the pot, ensuring the ingredients are well mixed. Secure the lid on your Instant Pot and set it to high pressure for 5 minutes. It will take approximately 5-10 minutes for the pot to come to pressure before the cooking timer begins.

Step 5: Release Pressure
After the cooking time is done, carefully perform a quick release of the pressure by turning the valve. Once the pressure has dropped, and the steam has escaped, gently open the lid. Take a moment to enjoy the fragrant aroma that fills your kitchen from the Instant Pot French Onion Soup.

Step 6: Prepare for Broiling
While the soup is releasing pressure, slice your baguette into about 6 pieces, each around 1/2 inch thick. Grate 3/4 cup of Gruyere cheese and preheat your oven to the broil setting. This preparation ensures a seamless transition to topping your soup once it’s ready.

Step 7: Assemble
Ladle the delicious soup into ramekins or oven-safe bowls. Place a slice of the prepared baguette on top of each serving, and generously sprinkle the grated Gruyere cheese over the bread. This adds the captivating cheesy layer your Instant Pot French Onion Soup deserves.

Step 8: Broil
Now, carefully place the assembled soup bowls under the broiler for 2-3 minutes, watching closely to prevent burning. You want the cheese to melt and bubble enticingly, creating a perfect golden crust on top of your soup. This final touch brings your comforting dish to life!

Make Ahead Options

These Instant Pot French Onion Soup instructions are perfect for busy home cooks looking to save time! You can caramelize the onions and season them up to 24 hours in advance. Store the sautéed onions in an airtight container in the refrigerator to maintain their rich flavor. When you’re ready to enjoy the soup, simply follow the same cooking steps, adding the prepped onions to the Instant Pot with your broth and wine. Alternatively, you can prepare the entire soup ahead of time and refrigerate it for up to 3 days without adding the baguette and cheese. Just reheat on the stovetop, assemble with fresh toppings, and broil for a delightful finish. This way, you’ll have the heartwarming taste of Instant Pot French Onion Soup ready to serve with minimal effort during your busy weeknights!

Instant Pot French Onion Soup Recipe FAQs

How do I select the best onions for this soup?
Absolutely! For the richest flavor, choose yellow onions as they caramelize beautifully and provide the sweetness needed for the soup. Look for onions that are firm and free from dark spots or blemishes. If yellow onions aren’t available, white onions may work, but the flavor will differ slightly.

How should I store leftover Instant Pot French Onion Soup?
Leftover soup can be securely stored in an airtight container in the fridge for up to 1 week. To maintain the best texture, I recommend keeping the toppings separate from the soup. Just reheat the soup gently on the stove or in the microwave before serving, adding fresh baguette and cheese for that delightful crunch!

Can I freeze Instant Pot French Onion Soup?
Very! To freeze, let the soup cool completely, then pour it into freezer-safe containers, leaving some space at the top as it may expand. It freezes well for 2-3 months. To reheat, thaw overnight in the fridge, then warm in a pot or microwave. Just remember to add fresh toppings when serving to keep it delightful!

What should I do if my soup is too salty?
If your soup turns out saltier than expected, don’t fret! You can balance the flavor by adding a bit of water or unsalted broth, or even introducing a peeled potato into the soup while warming it to absorb some of the salt. Let it simmer for around 10-15 minutes, and then remove the potato before serving.

Can I make this soup vegetarian?
Absolutely! To create a vegetarian version, simply substitute beef broth with vegetable broth and choose a vegetarian-friendly cheese such as mozzarella or a nut-based option. This way, you can enjoy the same comforting flavors without compromising dietary preferences. Enjoy crafting your vegetarian delight!

How long does it take to caramelize the onions?
Caramelizing the onions is crucial for building depth of flavor, and it typically takes about 15 minutes. You’ll want to stir them occasionally, allowing them to develop that gorgeous golden hue. Don’t rush this step—it’s all about the slow magic that enhances the taste of your Instant Pot French Onion Soup!
