Instant Pot French Onion Soup Ingredients
For the Soup
• Butter – Richness. Use unsalted butter for better control over the seasoning.
• Yellow Onions (10 medium-sized, sliced) – Base flavor. Best for sweetness and caramelization; white onions can be used but will alter the flavor.
• Salt & Pepper (½ tsp each) – Seasoning. Essential for flavor enhancement.
• Dried Thyme (½ tsp) – Aroma. Can substitute fresh thyme; use more as needed (about 1 tsp).
• Flour (2 tbsp) – Thickener. Helps coat onions and provide a slight thickening to the soup.
• Red Wine (½ cup) – Depth of flavor. Pinot Noir recommended, but use any dry red wine.
• Beef Broth (6 cups) – Base liquid. Chicken or vegetable broth may be substituted for dietary preferences, making this Instant Pot French Onion Soup gluten-free and vegetarian-friendly.
For the Toppings
• Baguette (6 slices, about ½ inch thick) – Texture. A crusty baguette is ideal; can substitute with any crusty bread.
• Gruyere Cheese (¾ cup, grated) – Creaminess and flavor. Substitute with Swiss, Emmental, Provolone, or mozzarella if desired.
Step‑by‑Step Instructions for Instant Pot French Onion Soup
Step 1: Sauté Onions
Set your Instant Pot to sauté mode and melt 4 tablespoons of unsalted butter. Add the sliced yellow onions, stirring frequently for about 15 minutes until they soften and turn deep golden brown. This technique enhances the natural sweetness of the onions, which forms the foundation of your luscious Instant Pot French Onion Soup.
Step 2: Season Onions
Once the onions are nicely caramelized, sprinkle in ½ teaspoon each of salt and pepper along with ½ teaspoon of dried thyme. Stir in the 2 tablespoons of flour, ensuring the onions are fully coated. This step not only adds flavor but also prepares the mixture for thickening your soup beautifully.
Step 3: Add Wine
Pour in ½ cup of dry red wine, such as Pinot Noir, and continue sautéing for another 1-2 minutes. This will help reduce the liquid and deepen the flavor profile of your Instant Pot French Onion Soup. Scrape any stuck bits from the bottom to incorporate all those delicious caramelized flavors.
Step 4: Pressure Cook
Now it’s time to transform your mixture into soup! Add 6 cups of beef broth to the pot, stirring well to combine. Seal the lid on the Instant Pot and set it to high pressure for 5 minutes. It will take about 5-10 minutes for the pot to come to pressure, so remain patient as the aromas build.
Step 5: Release Pressure
After the timer goes off, perform a quick release of the pressure by carefully turning the valve. Once the pressure gauge indicates it’s safe, open the lid and savor the rich aroma wafting from your Instant Pot French Onion Soup. Give the soup a gentle stir before preparing for the next steps.
Step 6: Prep Toppings
While the soup cools slightly, slice your baguette into ½-inch thick rounds and grate ¾ cup of Gruyere cheese. Preheat your oven to broil on high, ensuring a perfect melt for the cheese topping. The next step will bring everything together for an inviting presentation.
Step 7: Serve
Ladle the steaming soup into oven-safe bowls, placing a slice of baguette on top of each serving. Generously sprinkle grated Gruyere cheese over the bread, then carefully transfer the bowls to the oven. Broil for 2-3 minutes until the cheese is bubbly and golden, creating a mouthwatering finish to your Instant Pot French Onion Soup that’s perfect for sharing!

Instant Pot French Onion Soup Recipe FAQs
How do I select the right onions for my soup?
Absolutely! For the best flavor and sweetness, you should use yellow onions. They caramelize beautifully and provide a rich base for the soup. If they have any dark spots or are overly soft, it’s best to avoid those. White onions can be used, but they may alter the flavor profile slightly.
What is the best way to store leftovers?
Leftovers can be refrigerated in an airtight container for up to one week. Make sure the soup cools to room temperature before sealing to avoid condensation, which may affect its texture. Reheat on the stovetop or using the Instant Pot’s sauté function to warm it up gently and evenly.

Transfer it into freezer-safe containers, portioning it out for convenience, and it will keep well for up to 3 months. To enjoy, simply thaw overnight in the fridge and reheat on the stovetop, adding fresh baguette and cheese before broiling.
What if my soup turns out too salty?
If your soup is on the salty side, don’t fret! You can balance it out by adding a peeled, halved potato while reheating. The potato absorbs excess salt and can then be removed before serving. Alternatively, adding a splash of extra broth or water can also help dilute the saltiness.
Can this recipe be made gluten-free?
Very! To make your Instant Pot French Onion Soup gluten-free, simply substitute all-purpose flour with a gluten-free flour blend or cornstarch when thickening the soup. Also, ensure that the broth you use is labeled gluten-free. This way, you can easily enjoy a comforting bowl of soup without the gluten.
Is this soup safe for pets?
No, it’s best to avoid sharing this soup with your furry friends. Ingredients like onions and soaked bread can be harmful to pets, especially dogs. Always consult with your veterinarian if you’re uncertain about specific foods and their effects on pets.
