Ah, French Onion Soup—the ultimate cozy, savory, caramelized-onion comfort food! 🧅🥖🧀 Let’s go step by step so it comes out rich, flavorful, and beautifully golden on top.
Ingredients
- 4–5 large yellow onions, thinly sliced
- 3 tbsp butter (or a mix of butter and olive oil)
- 1–2 tsp sugar (helps with caramelization)
- 2–3 cloves garlic, minced
- 1 tsp salt
- ½ tsp black pepper
- 1–2 tbsp flour (optional, for slightly thicker broth)
- 6 cups beef broth (or a mix of beef and chicken broth for lighter flavor)
- ½ cup dry white wine or sherry (optional, adds depth)
- 1–2 tsp fresh thyme or 1 tsp dried thyme
- 1 bay leaf
- Baguette slices, toasted
- 1–2 cups shredded Gruyère cheese (or Swiss/Emmental mix)
Instructions
- Caramelize the onions
- Melt butter in a large pot over medium heat.
- Add onions and sugar, stirring occasionally.
- Cook slowly for 30–40 minutes until onions are deep golden brown. Patience is key!
- Add garlic and flour
- Stir in garlic and cook 30–60 seconds.
- Sprinkle flour over onions and stir to coat (optional—this thickens the soup slightly).
- Deglaze & simmer
- Pour in wine/sherry if using, scraping up any brown bits from the bottom.
- Add broth, thyme, bay leaf, salt, and pepper.
- Bring to a simmer and cook for 20–30 minutes. Remove bay leaf at the end.
- Prepare the toasts
- Slice baguette, toast lightly, or broil until golden.
- Assemble & broil
- Ladle soup into oven-safe bowls.
- Place a toasted baguette slice on top of each, then sprinkle generously with cheese.
- Broil 2–5 minutes until cheese is bubbly and golden brown.
Tips for the Best French Onion Soup
- Low and slow onions = maximum flavor. Don’t rush caramelization.
- Broth choice matters: Use rich, high-quality beef broth for deep flavor.
- Cheese melt: Gruyère is traditional because it melts beautifully and has nutty flavor.
- Make ahead: Soup can be made a day ahead; assemble and broil just before serving.
