French Onion Soup is a classic soup recipe for good reason! Sweet caramelized onions are simmered in a rich beefy broth to create a soup base that is loved by everyone!
Of course the best part of any french onion soup is the cheesy topping! A crusty bread crouton (or two) is topped with cheese and broiled until golden and bubbly! Who could ever resist?
This French Onion Soup recipe is one of the easiest, most elegant soups a home cook can perfect! Savory, a little bit sweet with just the right amount of soft golden onions for texture. Next to chicken noodle soup, a good French onion soup recipe is one of my favorites to warm your belly from the inside out!
The best French onion soup recipe can go from a simple beef broth with just onions all the way to a full, hearty soup with a raft of melted gruyere cheese over a slab of crusty bread. This easy French onion soup is right in the middle, simple, yet oh so upscale!
What Kind of Cheese for French Onion Soup
My favorite part of this French onion soup recipe is the cheese.
Gruyere is often used to top french onion soup because of its mild flavor and the way it melts perfectly over the bread. There are no hard and fast rules for a French onion soup cheese option and many people use a combination of mozzarella and parmesan cheese. Why not experiment with other soft, melty cheeses like Brie or Havarti, or even blue cheese crumbles?
How to Make French Onion Soup
While I often make Slow Cooker French Onion Soup, this stovetop version is one of my husband’s favorites!
It does take a bit of time, but don’t worry, it’s super easy. Most of the time spent is hands off (simmering etc) so this French Onion Soup recipe is great to make while you’re puttering around the house doing other tasks (or enjoying a glass of wine and a book, my happy place).
- Onions: Start with good quality onions for the best flavor. Walla Walla onions and Vidalia’s are large and sweet and meaty so a few will go a long way for this easy French onion soup. Take your time cooking the onions down to release their sweet flavor, making sure they are uniformly golden and soft. You want to make sure to do this at a lower temperature so they don’t brown. (Although you can also caramelize onions in the slow cooker the night before too)! If you’re using a sweeter onion, you can eliminate the bit of brown sugar.
- Season: Next, add the white wine and spices. Don’t worry about a particular variety of wine. French onion soup is very forgiving and the wine is really just an acidic base that helps marry all the flavors. If you have leftover red, use that. Even sherry or cognac will do!
- Simmer: Allowing time to simmer adds great flavor to this soup recipe! French onion soup broth should have a transparent caramel color to it, with a rich, full-bodied flavor that only gets better as it ages!
- Cheese: The best part of course! Ladle the soup into bowls (almost any ceramic bowl should be fine under a low broil) and top with bread and cheese. Broil until golden.
The best. Ever.
What to Serve with French Onion Soup
What “can’t” you serve with French onion soup? As a starter or an entrée, French onion soup is so versatile.
We serve it as a starter to baked chicken breasts, a steak dinner or roasted pork tenderloin. Eaten as a meal of it’s own, it can be paired simply with a salad, a side of sliced apples, pears and cheese or it can stand alone with extra crusty bread or seasoned croutons! Any way you serve it, a classic French onion soup will be a go-to recipe all year round!
