These French Onion Burgers are a tasty twist on the classic burger! With juicy beef patties topped with gooey melted cheese and sweet caramelized onions, they’re mouthwatering.
Who doesn’t love a burger that feels fancy? I often make these when I want to impress friends, but secretly, I just love the onion flavor. It’s like a party on a bun! 🎉
They’re super easy to make too! I just grill the patties, add the toppings, and enjoy. Perfect for summer BBQs or a cozy dinner at home!
Key Ingredients & Substitutions
Ground Beef: Using an 80/20 blend creates juicy burgers. If you’re looking for a leaner option, a 90/10 blend works too, but you might lose some juiciness. Alternatively, ground turkey or plant-based meat can be great substitutions for a lighter or vegetarian option.
Onions: Yellow onions are best for caramelizing due to their natural sweetness. If you want a slight bite, try red onions. For a milder flavor, you could use sweet onions like Vidalia or Walla Walla.
Beef Broth: Homemade broth adds depth, but store-bought is just fine if you’re in a pinch. For a vegetarian twist, use vegetable broth. It won’t be quite the same, but it keeps the flavor profile interesting.
Swiss Cheese: Swiss cheese gives that classic French onion flavor. If you want something stronger, Gruyère is a fantastic alternative. For a fun twist, try a melted cheddar for a different flavor experience!
Buns: Brioche buns are rich and soft, but any sturdy bun will work; ciabatta or whole grain are excellent choices. Just make sure they can hold all the delicious toppings!
How Do You Get the Best Caramelized Onions?
Caramelizing onions takes patience, but those sweet, rich flavors are worth it. First, start with medium heat and use a combination of butter and olive oil for a great flavor and higher smoke point. Stir the onions occasionally, allowing them to cook down evenly.
- Sauté onions slowly for 15-20 minutes, adjusting the heat to prevent burning.
- Add a pinch of salt earlier to help draw out moisture.
- Pour in the beef broth and Worcestershire sauce only after the onions are nice and soft.
- Cook until most liquid evaporates, leaving you with tender, sweet onions.
Remember, the longer and slower, the better the caramelization! If you find the onions browning too fast, lower the heat and give them time to develop flavor.

How Much Time Will You Need?
This delicious recipe takes about 15 minutes of prep time and 30 minutes of cooking, so you can have these tasty burgers ready in just about 45 minutes. Perfect for a satisfying dinner!
Step-by-Step Instructions:
1. Prepare the Onions:
Start by melting the butter with the olive oil in a skillet over medium heat. Once melted, add the sliced onions. Cook these onions for about 15-20 minutes until they are soft and golden brown, stirring them occasionally. Don’t forget to season with a little salt and pepper to bring out their sweetness!
2. Add Flavor:
Now, pour in the beef broth and Worcestershire sauce over the caramelized onions. Stir everything together and keep cooking until most of the liquid evaporates, leaving you with lovely, rich caramelized onions. When done, remove them from heat and set aside.
3. Form Patties:
While your onions are cooking, grab the ground beef. Divide it into four equal portions and gently shape each into a patty. Remember to make the patties a bit larger than your burger buns because they’ll shrink as they cook. Season both sides with salt and pepper to taste.
4. Cook the Patties:
Heat a grill or a skillet to medium-high. Cook your burger patties for about 4-5 minutes on each side for medium doneness. In the last minute of cooking, place a slice of Swiss cheese on top of each patty to let it melt beautifully.
5. Assemble the Burgers:
Toast your burger buns on the grill or skillet until they’re golden brown. On the bottom half of each toasted bun, stack the cooked patty with the melted cheese and add a generous serve of the caramelized onions on top.
6. Finish:
Top off each burger with the other half of the bun. If you like, add a sprinkle of fresh thyme for a nice touch.
7. Serve:
Your French Onion Burgers are ready to be served! Enjoy them warm with your favorite sides like crispy fries or a fresh salad. Bon appétit!
Can I Use Ground Turkey Instead of Beef?
Absolutely! Ground turkey is a great leaner alternative. Keep in mind that it may need a bit more seasoning than beef, so consider adding extra salt, pepper, or even some garlic powder to enhance the flavor.
How Can I Make This Recipe Gluten-Free?
No problem! Just use gluten-free buns and beef broth. Be sure to check the Worcestershire sauce label, as some brands contain gluten. You can also find gluten-free versions available at most grocery stores.
What Is the Best Way to Store Leftovers?
Store any leftover burgers and caramelized onions in separate airtight containers in the fridge for up to 3 days. To reheat, warm the patties in a skillet or the microwave. For the onions, a quick sauté in a pan will refresh their flavor beautifully!
Can I Prepare The Onions in Advance?
Yes, you can! Caramelized onions can be prepared a day ahead of time. Just store them in an airtight container in the fridge. When you’re ready to assemble the burgers, simply reheat them in a skillet until warmed through.
