French Onion Soup Recipe
Soup is often thought of as cold weather food but, I confess I'm a year-round soup fan. It's not unusual for me to make a pot of vegetable beef soup in the dead of summer often in an effort to use up fresh garden vegetables and to clean out my vegetable bin. A steamy bowl of loaded potato soup is always a comforting sight. Likewise, we'll devour taco soup any night of the week for dinner.
Helpful Tips for Making French Onion Soup
- Making French Onion Soup requires patience, and doing so will really show the love.
- Don't skimp on the amount of onions. After all, that's what this soup is all about.
- Please note, yellow onions will give a more intense onion flavor to this soup. Vidalia onions, which I love, will add sweetness. Either will work in the same amount, choose according to your own personal preference.
- Caramelizing onions is a process and the flavor forms the foundation for the entire dish. Give the onions ample time to brown to increase the depth of flavor.
- You can use red or white wine in this recipe. Preferably dry.
- Brandy is a standard ingredient in classic French onion soup. It gives a slightly sweet finish to the end product but, I find that a splash of sherry works beautifully, too.
- I highly recommend going with Gruyere for the over-sized cheesy bread topper for this dish. That being said, Swiss cheese is a suitable substitution.
