Ingredients for French Onion Soup Burgers
To make French Onion Soup Burgers, you’ll need a few key ingredients that are essential to replicating the flavors of French Onion Soup while still keeping the integrity of the burger.
For the Caramelized Onions:
- 2 large onions, thinly sliced
- 1 tablespoon butter
- 1 tablespoon olive oil
- 1/2 teaspoon sugar (optional, to help the caramelization)
- Salt and pepper to taste
- 1 tablespoon balsamic vinegar (optional, for extra depth)
For the Burger Patties:
- 1 pound ground beef (or your preferred protein, such as turkey, chicken, or plant-based)
- Salt and pepper to taste
- 1 teaspoon garlic powder (optional)
- 1 teaspoon onion powder (optional)
For the Soup-Infused Burger Sauce:
- 1/2 cup beef broth (preferably homemade or low-sodium)
- 1/4 cup heavy cream (optional, for creaminess)
- 1 tablespoon Worcestershire sauce
- Salt and pepper to taste
- A dash of thyme (optional, to add an herbal note)
For the Toppings:
- 4 slices Gruyère cheese (or Swiss cheese)
- 4 burger buns (preferably brioche or any bun that can hold up to the juicy toppings)
- Fresh parsley, chopped (optional)
How to Make French Onion Soup Burgers
Step 1: Caramelize the Onions
- In a large skillet, heat the butter and olive oil over medium heat.
- Add the sliced onions to the pan, and cook, stirring occasionally, for about 30-40 minutes. This will allow the onions to soften and turn golden brown. Add salt and pepper to taste.
- If you want to speed up the caramelization process, you can sprinkle a little sugar over the onions to help them brown more quickly.
- Once the onions are soft and caramelized, add the balsamic vinegar (if using) and stir well. Set the onions aside.
Step 2: Make the Soup-Infused Sauce
- In a small saucepan, combine the beef broth, Worcestershire sauce, and a dash of thyme (if using). Bring it to a simmer.
- Once simmering, reduce the heat and let it cook for about 5 minutes to concentrate the flavors.
- Add the heavy cream (if using) for extra richness, and stir to combine. Adjust salt and pepper to taste. Set aside.
Step 3: Prepare the Burger Patties
- While the onions are caramelizing, season the ground beef with salt, pepper, garlic powder, and onion powder.
- Form the beef into 4 even patties.
- Heat a grill or skillet over medium-high heat and cook the patties for about 4-5 minutes on each side, or until they reach your desired level of doneness. For a medium burger, the internal temperature should be around 160°F (71°C).
- During the last minute of cooking, place a slice of Gruyère cheese on each patty to melt.
Step 4: Assemble the Burger
- Toast the burger buns lightly on the grill or in a toaster.
- Place a cooked burger patty on the bottom half of each bun.
- Top with a generous spoonful of caramelized onions.
- Drizzle some of the soup-infused sauce over the onions.
- Add the top bun and serve immediately.
Tips for the Perfect French Onion Soup Burger
- Choosing the Right Beef: While ground beef is the most common choice for burgers, you can experiment with different meats such as lamb, turkey, or even veggie patties for a lighter version.
- Cheese Options: Gruyère is the traditional cheese used for French Onion Soup, but Swiss cheese, mozzarella, or even cheddar can work well in this burger. The key is to use a cheese that melts well and adds creaminess.
- Buns Matter: Opt for sturdy buns like brioche or potato buns that won’t fall apart under the weight of the juicy burger and toppings.
- Soup Broth: For a more authentic French Onion Soup taste, you can use homemade beef broth or a high-quality store-bought version. Avoid using too much salt if your broth is already seasoned.
- Add Extra Flavor: To bring more depth to your burger, you can add a touch of Dijon mustard, sautéed mushrooms, or even a little garlic powder to the beef patty mix.
Serving Ideas for French Onion Soup Burgers
French Onion Soup Burgers are filling on their own, but here are some great side dish ideas to complement the richness of the burger:
- Crispy Fries: Classic fries or sweet potato fries pair perfectly with the savory, melty burger.
- Mixed Green Salad: A light, fresh salad with a tangy vinaigrette helps balance the richness of the burger.
- Soup Starter: Serve a small bowl of classic French Onion Soup as a starter, making for a fun, thematic meal.
- Pickles or Pickled Veggies: A bit of acidity from pickles or pickled onions helps cut through the richness of the burger.
