Recipe Tips

Caramelize the Onions Slowly: The key to a great French onion soup is perfectly caramelized onions. Take your time with this step—cooking the onions slowly over low heat allows them to develop a deep, sweet flavor.

Use Good Quality Beef Broth: Since the broth is the base of your soup, using a high-quality beef broth will make a big difference in the overall flavor.
Toast the Bread: Toasting the bread before adding it to the soup helps it hold up better under the cheese and prevents it from becoming too soggy.
Choose the Right Cheese: Gruyère cheese is traditionally used for French onion soup because of its excellent melting qualities and nutty flavor. However, you can also use Swiss or a mix of cheeses if you prefer.

Broil Carefully: When broiling the cheese-topped soup, keep a close eye on it. Cheese can go from perfectly melted to burnt very quickly, so don’t step away from the oven.

FAQs

Can I use vegetable broth instead of beef broth?

Yes, you can substitute vegetable broth if you prefer a vegetarian version of the soup. However, keep in mind that the flavor will be slightly different and less rich compared to using beef broth.

What’s the best type of bread to use for this soup?

A crusty French baguette works best for French onion soup. It holds up well in the broth and provides a nice texture contrast.

Can I make this soup ahead of time?

Absolutely! The soup can be made ahead and stored in the fridge for up to 3 days. When you’re ready to serve, simply reheat the soup, add the bread and cheese, and broil until the cheese is melted.

Is there a way to make this soup gluten-free?

Yes, you can use gluten-free bread for the topping, and make sure your beef broth is gluten-free as well.

How can I store leftovers?

Leftover soup can be stored in an airtight container in the fridge for up to 3 days. When reheating, add fresh bread and cheese before serving.

What To Serve with Longhorn French Onion Soup Recipe

Longhorn French Onion Soup is delicious on its own, but it also pairs well with a variety of sides. Here are some ideas:

A Simple Green Salad: The fresh, crisp flavors of a green salad with a light vinaigrette provide a nice contrast to the rich soup.
Garlic Bread: For an extra dose of flavor, serve the soup with a side of garlic bread. The crunchy, garlicky bread is perfect for dipping into the broth.
Roasted Vegetables: A side of roasted vegetables adds color and nutrition to the meal, balancing out the richness of the soup.

Grilled Cheese Sandwich: For a more filling meal, pair the soup with a grilled cheese sandwich. The extra cheese complements the cheesy topping on the soup.
A Light Dessert: Finish your meal with something light, like a fruit salad or a sorbet, to cleanse the palate after the savory soup.

Storage Tips

Refrigerate: Store any leftover soup in an airtight container in the refrigerator. It will stay fresh for up to 3 days.

Reheat: To reheat, warm the soup in a pot over low heat, stirring occasionally until heated through. You can also microwave it in a microwave-safe bowl.
Freeze: If you want to store the soup for longer, freeze it without the bread and cheese. Pour the cooled soup into freezer-safe containers, leaving some space for expansion. It can be frozen for up to 3 months.
Thaw: To thaw, transfer the soup from the freezer to the refrigerator and let it thaw overnight.

Serve Fresh: When ready to serve, reheat the soup, toast fresh bread, and add cheese before broiling as instructed.
