French Onion Burgers are a tasty twist on the classic burger! Juicy beef patties are topped with sweet, caramelized onions and melted cheese, making every bite extra special.
It’s like having a comforting bowl of French onion soup, but in sandwich form! I love serving these with crispy fries. Trust me, once you try them, you’ll want to make them again and again! 🍔
Key Ingredients & Substitutions
Ground Beef: Using an 80/20 blend gives great flavor and juiciness. If you’re looking for a healthier option, you can use ground turkey or chicken, but be careful not to overcook them, as they can dry out quickly.
Onions: Large yellow onions work best for caramelizing. They develop a sweet flavor. You can substitute with sweet onions or even red onions for a slightly different taste.
Cheese: Swiss cheese is classic for French onion burgers, but Gruyère adds a nice nutty flavor. If these aren’t available, mozzarella or provolone would make good substitutes.
Butter: Using a mix of butter and olive oil helps prevent burning while caramelizing onions. If you want to avoid dairy, you can use a plant-based butter instead.
Buns: Brioche adds a lovely sweetness, but you can use any other type of burger bun. Whole wheat or gluten-free buns work well if you’re looking for healthier or dietary-friendly options.
How Do You Caramelize Onions Perfectly?
Caramelizing onions is key to getting that rich, sweet flavor for your burgers. Here’s how to do it right:
- Heat your skillet over medium heat and add butter and olive oil.
- Add the sliced onions, stirring occasionally to prevent sticking.
- After about 10 minutes, add the beef broth to help deglaze the pan, scraping up the brown bits.
- Continue cooking until they become golden and soft, usually 15-20 minutes total. Patience is key—low and slow wins here!

Step-by-Step Instructions:
1. Preparing the Burger Patties:
Start by combining the ground beef in a large bowl with Worcestershire sauce. Season generously with salt and pepper, and mix gently with your hands. Don’t overwork the meat! Form the mixture into 4 equal burger patties and set them aside.
2. Caramelizing the Onions:
In a large skillet, add the olive oil and 1 tbsp of butter over medium heat. Once the butter has melted, add the thinly sliced onions. Cook them slowly, stirring occasionally for about 15-20 minutes until they become caramelized and turn golden brown. Halfway through, pour in the beef broth to deglaze the pan and bring out the deep flavors of the onions.
3. Cooking the Burgers:
While the onions are caramelizing, heat a separate skillet or grill over medium-high heat. Grill or pan-fry the burger patties for about 4-5 minutes on each side, or until they are cooked to your desired doneness. In the last minute of cooking, place a slice of cheese on each patty and cover to let it melt.
4. Toasting the Buns:
While the burgers are finishing up, take the remaining 1 tbsp of butter and use it to lightly toast the burger buns in the skillet or on the grill until they are golden brown. This adds a nice crunch and flavor!
5. Assembling the Burgers:
It’s time to put everything together! Start with the bottom half of each toasted bun, place a juicy burger patty on top, and then load it up with the caramelized onions. Add a smear of French onion dip or sauce on top before placing the top half of the bun on.
6. Garnishing and Serving:
For a lovely touch, sprinkle some fresh thyme on top if you like. Serve your French onion burgers immediately, and enjoy the mouthwatering flavors!
## FAQ
Can I Use Ground Turkey Instead of Ground Beef?
Yes, you can substitute ground turkey! Just keep in mind that turkey is leaner than beef, so it might require a bit more seasoning to enhance the flavor. You may also want to cook it until it reaches an internal temperature of 165°F to ensure it’s fully cooked.
How Do I Caramelize Onions Faster?
If you’re short on time, you can add a pinch of sugar to the onions as they cook. This will help them brown quicker. However, be careful not to burn them; keep stirring and reduce the heat if necessary to ensure a sweet and savory flavor.
Can I Make the Patties in Advance?
Absolutely! You can prepare the burger patties up to a day ahead. Just shape them, cover with plastic wrap, and refrigerate. This not only saves time, but it also allows the flavors to meld.
What Should I Do with Leftover Caramelized Onions?
Leftover caramelized onions can enhance many dishes! Store them in an airtight container in the fridge for up to a week. Add them to sandwiches, salads, or even as a topping for pizzas for added flavor!
