Step-by-Step Guide to Making Easy French Onion Soup
Step 1: Caramelize the Onions
The first step in this easy French onion soup recipe is to caramelize the onions. This process is crucial as it develops the deep, sweet flavor that defines the soup.
- Slice the Onions: Thinly slice the onions to ensure even cooking.

Step 2: Build the Broth
Once the onions are caramelized, it’s time to build the broth.
- Deglaze with Wine: Pour in the white wine, scraping up any browned bits from the bottom of the pot. The wine should be reduced by half after simmering.

- Season to Taste: Remove the bay leaves and adjust the seasoning with salt and pepper.

Step 4: Assemble and Serve
Now comes the fun part—assembling the soup.
- Ladle the Soup: Spoon the soup into dishes that can be baked.
