• 1/2 cup Dry Red Wine (optional but recommended!)

How to Make Easy French Onion Soup (Step-by-Step)

1. Caramelize the onions

Start by sautéing the onions and butter in your pressure cooker or a large soup pot. If you are adding mushrooms, add them in at this time as well. Stir frequently, scraping the bottom to prevent burning. This step can take up to 25 minutes, but don’t rush it—perfectly caramelized onions are the key to amazing French onion soup.

2. Add garlic and herbs

Once the onions turn a deep golden brown, stir in the garlic and dried thyme. Let them cook for a minute until fragrant.

3. Deglaze with red wine

Pour in the red wine and cook uncovered until it reduces and the alcohol cooks off. This adds depth and a restaurant-quality flavor to your soup, but it’s optional if you prefer to skip it.

4. Add flour

Sprinkle the flour over the onions and stir for one minute to cook out the raw flour taste. This helps thicken the broth slightly.

5. Add broth and simmer

Stir in the beef broth and bay leaf.

• Pressure Cooker Method: Cook for 10 minutes on high, then release pressure.
• Stovetop Method: Simmer on low for 25 minutes, stirring occasionally. Remove the bay leaf before serving.

6. Add the iconic cheesy bread topping

You have two options:

Steam Method (pressure cooker)

Place a toasted baguette slice on top of the soup, then a slice of provolone. Add the lid and let the cheese steam and melt for 1 minute.

Broiler Method (classic French onion style)

Ladle the soup into oven-safe bowls. Place a toasted baguette slice on top, add the provolone, and broil at 450°F for 30 seconds to 1 minute until bubbly and golden.

This gooey, melty cheese blanket is what makes French onion soup so iconic—and utterly irresistible.
