How to Assemble

- Pour in all of the beef stock now. Bring the liquid to a light boil. Simmer the soup for about 20 minutes.
- Toast your baguette slices in the oven. They should be golden and very crispy. This prevents the bread from getting soggy.

- Put the bowls under the broiler. Watch them closely for two minutes. Remove when the cheese is brown and bubbly.
Recipe Success Tips

How To Store Leftover
- You can store the liquid soup easily. Keep it in a sealed jar for three days. Do not store it with the bread or cheese.
- Reheat the soup on the stove top. Add fresh bread and cheese before serving again. You can also freeze the broth for two months. Thaw it in the fridge overnight before heating.
Sides & Pairings Suggestions
- This soup is very filling on its own. You can serve it with a simple green salad. A light vinaigrette cuts through the heavy cheese.
- A glass of red wine pairs very well. Try a Pinot Noir or a light Merlot. Some roasted chicken also makes a great side. Keep the sides simple to let soup shine.

FAQs about Bobby Flay French Onion Soup Recipe

A: Yellow onions are best for sweetness. Red onions change the color too much. Stick to yellow or white onions for flavor.
