How to Make Instant Pot French Onion Soup Recipe
Step 1: Saute the Onions
Start by turning your Instant Pot to sauté mode and melting the butter until it’s foamy. Add the sliced yellow onions and cook them slowly, stirring occasionally for about 15 minutes. This process is what builds that irresistible caramel flavor; make sure to scrape the bottom often to prevent burning and to encourage even browning.
Step 2: Add Seasoning and Flour
Once the onions are beautifully browned, sprinkle in salt, pepper, dried thyme, and flour. Stir everything together so the flour coats the onions, acting as a thickening agent once the liquids are added. Then pour in the red wine and continue to sauté for an additional 1 to 2 minutes, allowing some of the alcohol to evaporate, leaving behind a rich undertone.
Step 3: Pressure Cook the Soup
Pour the beef broth into the Instant Pot with the onion mixture and secure the lid, making sure the valve is set to seal. Select the pressure cook function on high and set the timer for 5 minutes. The Instant Pot will take about 5 to 10 minutes to come to pressure before it starts cooking. This quick pressure cooking melds all the flavors beautifully while saving you loads of time.
Step 4: Release Pressure and Prepare Toppings
Once cooking is complete, perform a quick release by carefully turning the valve to vent. Wait for the pressure gauge to drop and open the lid. While the soup is hot and fresh, preheat your oven’s broiler to high and get your baguette slices and grated Gruyere cheese ready for assembly.
Step 5: Broil with Baguette and Cheese
Ladle the steaming soup into oven-safe bowls or ramekins. Place a slice of baguette on top of each bowl and generously sprinkle the grated Gruyere over the bread. Slide the bowls under the broiler for 2 to 3 minutes, watching closely to ensure the cheese melts perfectly with a bubbly, golden-brown crust without burning.
Step 6: Serve
Remove the bowls from the oven, let them cool just slightly, and then dig in. This Instant Pot French Onion Soup Recipe is guaranteed to delight your taste buds with its combination of sweet onions, savory broth, and ooey-gooey cheesy bread all in one comforting bowl.
How to Serve Instant Pot French Onion Soup Recipe
Garnishes
Simple garnishes can elevate your soup to a whole new level. Fresh thyme sprigs add a bright herbal note, while a sprinkle of chopped parsley provides a pop of color that contrasts beautifully with the browned cheese. For an extra savory touch, a dash of freshly ground black pepper can awaken the flavors right before serving.
Side Dishes
While this soup stands strong on its own, pairing it with light, fresh sides balances the richness. A crisp green salad with a tangy vinaigrette is classic, or opt for roasted vegetables to keep the meal hearty yet wholesome. Garlic bread is another great choice to extend the delicious crunch and soak up every last drop of soup.
Creative Ways to Present
Serve the soup in charming individual ramekins for a classy dinner party vibe or rustic ceramic bowls for casual family dinners. For an eye-catching presentation, drizzle some extra melted Gruyere around the rim or add a small wedge of baguette alongside the bowl with a butter spread. These details make the experience feel special and invite your guests to savor every bite.
Make Ahead and Storage
Storing Leftovers
This Instant Pot French Onion Soup Recipe keeps beautifully in an airtight container in the refrigerator for up to 3 days. Store the baguette slices and cheese separately to preserve their texture. When you’re ready to enjoy leftovers, you can reheat the soup on the stovetop to maintain its rich flavor.
Freezing
You can freeze the soup without the bread and cheese for up to 2 months. Use freezer-safe containers or heavy-duty freezer bags, leaving space for expansion. Thaw the soup overnight in the refrigerator before reheating gently on the stove. Always add fresh baguette and Gruyere at serving time for the best texture.
Reheating
Reheat your leftover soup in a pot over medium heat, stirring occasionally until it’s hot and bubbling. If you want to recreate the broiled cheese topping, ladle the warmed soup into oven-safe bowls, top with baguette slices, sprinkle with Gruyere, and place under the broiler until bubbly and golden.
FAQs
Can I use different types of cheese for this soup?
Gruyere is traditional because it melts well and offers a nutty flavor, but you can experiment with Swiss, Emmental, or even mozzarella if you prefer a milder taste or don’t have Gruyere on hand.
Is it necessary to use red wine in the recipe?
The red wine adds an important layer of acidity and depth, but if you prefer to omit alcohol, you can substitute with more beef broth and a splash of balsamic vinegar for a similar tangy effect.
Can this recipe be made vegetarian?
You can easily make a vegetarian version by using vegetable broth instead of beef broth. Keep the other ingredients the same for a deliciously rich and satisfying soup without meat.
What size Instant Pot is best for this recipe?
A 6-quart Instant Pot is perfect for this recipe, providing enough room for the onions to brown evenly and the soup to pressure cook without overflowing.
How do I prevent the onions from burning during sautéing?
Be sure to stir frequently and scrape the bottom of the pot often to avoid burning. Lower the sauté heat if your Instant Pot allows, and don’t rush the caramelization — patience is key for that perfect sweet onion flavor.
