French Onion Soup Burger Ingredients
• Here’s what you need to create your indulgent French Onion Soup Burger!
For the Burger Patty
• Ground Beef (80/20 Blend) – This blend guarantees a juicy burger that’s bursting with flavor; feel free to substitute with ground turkey or chicken for a lighter choice.
• Kosher Salt – Essential for enhancing all the flavors in the burger; you can use regular table salt, but keep the amount the same.
• Freshly Ground Black Pepper – Adds a hint of warmth; adjust to your taste preference.
• Vegetable Oil – Helps achieve a nice sear on the burger; can be replaced with canola or grapeseed oil.
For the Caramelized Onions
• Thickness-cut Bacon – Brings a savory crunch and depth of flavor; turkey bacon is a leaner alternative.
• Yellow and Red Onions – Sweet and rich, these onions caramelize beautifully; you can use only yellow or white onions if preferred.
• Kosher Salt – Enhances the sweetness of the onions during caramelization; regular salt will work in a pinch.
• Granulated Sugar – Speeds up the caramelization process; feel free to use brown sugar for a richer flavor.
• Beef Stock – Provides a depth of flavor to the caramelized onions; vegetable broth makes a great non-meat substitute.
For the Garlic Aioli
• Mayonnaise – The creamy base for your aioli; Greek yogurt serves as a lighter option.
• Extra-virgin Olive Oil – Adds a rich flavor to the aioli; you can replace it with any neutral oil.
• Garlic – Freshly minced garlic bumps up the flavor; garlic powder works too in a pinch.
For the Burger Assembly
• Shredded Gruyère Cheese – Offers a rich, melty texture; swap with Swiss or provolone if needed.
• Unsalted Butter – For toasting the burger buns and adding richness; margarine can be used for a dairy-free alternative.
• Wild Arugula – Provides a peppery bite that balances the richness of the burger; baby spinach can be a good substitute if arugula is unavailable.
• Burger Buns – Your choice of buns to cradle this delicious creation; brioche or ciabatta can elevate the burger experience.

How to Make French Onion Soup Burger
-
Caramelize the Bacon and Onions: Start by cooking the thick-cut bacon in a skillet over medium heat until crispy, about 5-7 minutes. Remove the bacon, then sauté the sliced yellow and red onions in the same skillet with the bacon fat and a splash of extra-virgin olive oil. Season with kosher salt and granulated sugar, cooking until they turn a deep golden brown, around 25-30 minutes. Stir in the beef stock and let it simmer until slightly thickened.
-
Prepare the Garlic Aioli: In a small bowl, mix together the mayonnaise, extra-virgin olive oil, and minced garlic until smooth. Set it aside to let the flavors meld.
-
Cook the Burger Patties: Shape the ground beef into square-shaped patties, about 1 inch thick, and season both sides generously with kosher salt and freshly ground black pepper. Heat vegetable oil in a cast-iron pan over medium-high heat. Cook the patties for about 3 minutes on each side, adding the shredded Gruyère cheese on top during the last minute of cooking to melt.
-
Toast the Buns: In another pan, melt unsalted butter over medium heat. Place the burger buns cut-side down in the pan, toasting them until they are golden brown and slightly crispy.
-
Assemble the Burgers: Start by spreading the garlic aioli on the top bun. Place the melted cheese patty on the bottom bun, then layer on the caramelized onions, crispy bacon, and a handful of wild arugula. Close with the top bun and serve immediately for a mouthwatering experience!
Optional: Pair your burger with sweet potato fries for a delightful crunch!

Expert Tips for the French Onion Soup Burger

Don’t Rush Caramelization: Take your time with the onions; letting them cook slowly will bring out their natural sweetness and prevent bitterness.

-
Use an Indentation: Creating a small dent in the center of each patty before cooking helps prevent bulging, resulting in a perfectly shaped French Onion Soup Burger.
-
Cheese Meltdown: Add the shredded Gruyère cheese during the last minute of cooking for the ultimate gooey texture.
-
Try Different Greens: Feel free to switch arugula for other greens like spinach or mixed salad for a fresh twist on your burger assembly!

French Onion Soup Burger Recipe FAQs
What type of onions should I use for caramelizing?
I recommend using yellow and red onions for their sweet, rich flavors when caramelized. If you prefer, you can stick to using only yellow or white onions, as they also work beautifully in this recipe.
How long can I store leftover French Onion Soup Burgers?
Leftover burgers should be stored in an airtight container in the fridge for up to 3 days. When ready to enjoy them again, reheat in a skillet over medium heat to help maintain their tenderness and flavor.
Can I freeze the burger patties?
Absolutely! To freeze cooked burger patties, wrap them tightly in plastic wrap, then place them in a freezer-safe bag to prevent freezer burn. They can remain frozen for up to 3 months. When you’re ready to use them, thaw overnight in the fridge, and then warm them in the oven at 350°F (175°C) for about 10-15 minutes until heated through.
What if my onions don’t caramelize properly?
If your onions aren’t caramelizing, ensure you’re cooking them over medium-low heat and giving them plenty of time. It usually takes about 25-30 minutes for onions to reach the perfect deep, golden brown color. Stir occasionally to prevent sticking or burning. If they are still raw after 10 minutes, add a pinch of salt and sugar to accelerate the caramelization process!
Can I substitute any ingredients due to dietary restrictions?
Certainly! You can swap the beef stock for vegetable broth to make this dish vegetarian-friendly. For a lighter option, use ground turkey instead of beef. If you or your guests have dairy allergies, consider using dairy-free cheese and margarine instead of butter. Always feel free to explore alternatives that suit your dietary needs—there are plenty of delicious options!
How can I make the garlic aioli lighter?
A great alternative to regular mayonnaise in the garlic aioli is Greek yogurt, which provides a creamy base with less fat. Simply replace the mayonnaise with an equal amount of Greek yogurt and keep the garlic and olive oil for that rich flavor. I often recommend this for a lighter, tangy twist!
