Red wine French onion soup and gruyere toast is one of our favorite soup recipes to make. Caramelized onions, red wine, beef broth or beef stock come together with a bit of thyme. This is such a simple soup. You just need a little patience to allow the onions to caramelize.
If you plan things out, you can actually get home from work, get the onions going, and let them do their magic. We like to serve this French onion soup with a crispy, cheesy baguette slice. Bruce came up with the idea of making the cheese toasts in the oven on parchment for easy clean up. You can then just serve them on top of the French onion soup, and pour a glass of red wine!
Can I use white wine instead of red wine?
Absolutely, you can make the swap for wine depending on your taste. The red wine will give it a deeper, richer look and flavor, but a crisp white wine will also be very flavorful. And don’t worry, the alcohol cooks out!
Can I make this soup vegetarian or vegan?
Of course! Swap the beef broth out for vegetable broth. Use vegetable or garlic bouillon instead of beef bouillon. When making the toast, just substitute a plant based cheese for the top of the baguette.
What is a good side dish to serve the French Onion soup with?
Our favorite pairing for this French onion with red wine is a caesar salad. We make up our homemade caesar dressing and keep it in the fridge. All you need is romaine lettuce, as you can use one of the pieces of cheese toast for the crouton! How delicious is that?

What is the history of French Onion soup?
French onion soup originates in Paris, France in the 18th century, made from beef broth, and caramelized onions. It was introduced to the United States by the New York restaurant of Henri Mouquin in 1861, where his wife Marie Julie Grandjean Mouquin was the chef.
Does the red wine cook out of the French onion soup?
Yes, you can serve soup with alcohol to children since the alcohol is burned off in the simmering process. Regardless if you use red wine, white wine or brandy, the cooking process will burn off all the alcohol.
What are the best onions to use in French onion soup?
Most onion varieties will work. We find that the combination of sweet onions, shallots & red onions give this soup a nice depth of flavor.
