👨🍳 Step-by-Step How to Make French Onion Soup
1. Caramelize the Onions
Heat butter and oil in a large pot. Add sliced onions and cook on low heat for 30–40 minutes, stirring occasionally until golden brown.
➡️ This step builds the signature sweet, deep flavor.
2. Add Seasoning
Sprinkle salt, pepper, and sugar. Cook for a few more minutes until onions are deeply caramelized.
3. Deglaze the Pot
Pour in white wine (optional) and scrape the bottom to release flavor bits.
4. Add Broth & Herbs
Add beef broth, thyme, and bay leaf. Bring to a boil, then simmer for 20–30 minutes.
5. Prepare Bread
Toast baguette slices until crisp.
6. Assemble
Pour soup into oven-safe bowls. Place toasted bread on top and cover with cheese.
7. Broil
Broil for 2–5 minutes until cheese melts and turns golden brown.
8. Serve Hot
Serve immediately while the cheese is bubbly and delicious.
