Ingredients Needed

Yellow onions (4-5 medium-sized) – The key to the soup’s rich flavor. Yellow onions caramelize beautifully, giving that classic, sweet undertone that French onion soup is known for.
Ground beef (1 lb) – Opt for ground beef with a little fat content (about 80/20). This ensures the patties stay juicy and flavorful.
Beef broth (4 cups) – A must for that deep, savory base. If you have homemade stock, even better!
Butter (2 tbsp) – For sautéing the onions and adding richness.
Olive oil (1 tbsp) – For cooking the onions alongside the butter.
Garlic cloves (3-4, minced) – Adds another layer of flavor that complements the onions perfectly.
Dried thyme (1 tsp) – For an earthy touch that balances the sweetness of the onions.
Bay leaf (1) – For added depth and complexity.
Worcestershire sauce (1 tbsp) – Gives the broth a little tang and richness, taking the flavor to another level.
Salt and black pepper (to taste) – Essential for seasoning.
Bread (French baguette or crusty loaf) – Sliced into thick pieces for croutons that soak up the broth and add texture.
Gruyère cheese (1-2 cups, shredded) – A melty, slightly nutty cheese that’s perfect for French onion soup.
Parmesan cheese (½ cup, grated) – For a sharp, salty finish on the croutons.
Ground beef seasoning (optional, for the patties) – You can use a simple salt-and-pepper seasoning or your favorite burger seasoning.

Cooking Instructions

Caramelize the onions: Start by heating a large pot over medium heat and adding the butter and olive oil. Once the butter has melted, add the sliced onions. Sauté for about 10 minutes, stirring occasionally to prevent burning. Reduce the heat to low and cook for another 30-40 minutes, stirring occasionally, until the onions are a deep golden brown. The slow caramelization is key to developing that signature sweet flavor.
Add garlic and seasonings: Once the onions are nicely caramelized, add the minced garlic, thyme, and bay leaf. Stir everything together and cook for 1-2 minutes until fragrant. Then, pour in the beef broth, followed by the Worcestershire sauce, salt, and pepper. Bring it to a simmer, cover, and cook for another 15-20 minutes to allow the flavors to meld together.
Cook the burger patties: While the soup is simmering, form the ground beef into 4-6 patties (depending on size). Season with salt and pepper or any of your preferred seasonings. In a separate pan, heat a little oil over medium-high heat and cook the patties for about 4-5 minutes per side, or until they reach your desired doneness. Once done, set the patties aside to rest.
Prepare the croutons: While the soup and patties are cooking, preheat your oven to 400°F (200°C). Slice the bread into thick pieces and place them on a baking sheet. Brush with a little olive oil and sprinkle with salt and pepper. Toast in the oven for 5-7 minutes, flipping once, until they’re golden and crispy.
Assemble the soup: Ladle the onion soup into bowls. Place a burger patty on top of each bowl of soup. Lay the toasted crouton slices on top of the burger patties. Generously sprinkle with Gruyère and Parmesan cheese.
Broil the soup: Place the bowls under the broiler in your oven for 2-4 minutes, or until the cheese is bubbling and golden brown. Watch carefully so the cheese doesn’t burn!
Serve and enjoy: Remove from the oven, let cool for a minute, and serve your Hamburger French Onion Soup hot with a sprinkle of fresh herbs or extra grated Parmesan, if desired.

Ingredient Insights

Caramelized onions: These are the heart of the dish. The slow cooking process brings out the natural sugars in the onions, making them tender, sweet, and deeply flavorful. It’s time-consuming, but the payoff is worth it.
Beef broth: The base of this soup needs to be rich to stand up to the caramelized onions and the burger patties. Store-bought broth is fine, but using homemade beef stock will really elevate the flavor.
Gruyère cheese: This Swiss cheese is famous for its meltability. It’s perfect for French onion soup, adding a creamy, nutty finish that ties the whole dish together.

Expert Tips

Caramelize on low heat: You might be tempted to speed up the caramelization by turning the heat up, but patience is key. Low and slow brings out the sweetness in the onions.
Seasoning the beef: Don’t skimp on seasoning the burger patties. The beef is the star of the show, so make sure the patties are flavorful. You can mix in herbs like rosemary or garlic powder for an extra depth of flavor.
Make it ahead: This soup actually tastes even better the next day as the flavors have more time to meld. You can prepare the soup base and the patties in advance, then assemble and broil just before serving.
Use a broiler-safe bowl: For the best results, make sure you’re using a bowl that can go under the broiler. This will help the cheese melt beautifully and get that irresistible golden crust.

Recipe Variations

Vegetarian Version: Swap out the ground beef for a veggie patty or even a portobello mushroom cap. You can still use the beef broth or opt for vegetable broth to keep it vegetarian-friendly.
Cheese Variety: While Gruyère is the traditional choice, you can experiment with other cheeses like mozzarella, cheddar, or even fontina for a different twist. Just make sure the cheese melts well!
Add Wine: Some classic French onion soups use white wine for deglazing. You can add a splash of dry white wine to the soup base after caramelizing the onions to enhance the flavor profile.
Spicy Kick: For a bit of heat, add some red pepper flakes or even a slice of jalapeño to the soup for a spicy twist.
