These Easy French Onion Burgers are a tasty treat! Juicy beef patties are topped with sweet, caramelized onions and gooey melted cheese. Perfect for a satisfying meal!
When I make these burgers, I always end up drooling over the melted cheese. It’s hard to resist sneaking a bite while they cook! They’re so easy to whip up on a busy day.
Key Ingredients & Substitutions
Ground Beef: I prefer 80% lean for the best flavor and juiciness. If you’re looking for a leaner option, you can use turkey or chicken. Just make sure to season well to keep it flavorful!
Onions: Yellow onions are ideal because they caramelize beautifully. If you’re short on time, you could use red onions for a slightly sharper taste or even shallots for a milder flavor.
Swiss or Gruyère Cheese: These cheeses melt beautifully, but feel free to swap with cheddar or provolone if that’s what you have on hand. Each will give a different taste, but they still work great!
Brioche Buns: I love using soft brioche buns for their sweetness and texture. If you need a gluten-free option, use gluten-free buns or lettuce wraps for a lighter version.
How Can I Make the Best Caramelized Onions?
Caramelizing onions may seem tricky, but it’s all about patience. Here’s how to get those deliciously sweet onions right:
- Heat butter and olive oil in a skillet over medium-low heat.
- Add thinly sliced onions along with sugar to help them caramelize. A pinch of salt enhances the sweetness too.
- Cook slowly for about 25-30 minutes, stirring occasionally. The key is low heat—don’t rush it!
- Once they are golden brown, stir in balsamic vinegar for a touch of tang. If desired, splash in some beef broth for more depth. Remove from heat when done.
These onions add amazing flavor to your burgers, so don’t skimp on this step!

How Much Time Will You Need?
This delicious burger recipe takes about 40 minutes to prepare. You’ll spend around 30 minutes cooking the caramelized onions and patties, with some additional time to toast the buns and assemble everything. A complete meal ready to enjoy in no time!
Step-by-Step Instructions:
1. Caramelize the Onions:
In a large skillet, melt the butter with the olive oil over medium-low heat. Add the thinly sliced onions, sugar, and a pinch of salt. Cook slowly, stirring occasionally, for about 25-30 minutes. You want them to be very soft, golden brown, and beautifully caramelized. After that, stir in the balsamic vinegar and cook for another 2 minutes until it reduces. If you like, add a splash of beef broth or French onion soup for extra flavor. Remove the skillet from heat and set the caramelized onions aside.
2. Prepare the Patties:
While the onions are cooking, take the ground beef and divide it into 4 equal portions. Form each portion into a patty. Season both sides generously with salt and freshly ground black pepper so that every bite is flavorful!
3. Cook the Burgers:
Heat your grill pan or skillet over medium-high heat. Once hot, add the burger patties. Cook for about 4 minutes on one side until a nice crust forms. Flip the patties over and immediately place a slice of Swiss or Gruyère cheese on top of each patty. Cover the pan loosely with a lid to help the cheese melt. Continue cooking for another 3-4 minutes, or until the cheese is melted and the burger is cooked to your liking.
4. Toast the Buns:
While the burgers are cooking, toast the buns lightly on the grill or pop them into a toaster. This adds a lovely crunch and prevents the buns from becoming soggy.
5. Assemble the Burgers:
Start by spreading a generous amount of caramelized onions on the bottom half of each toasted bun. Place the cheesy burger patty on top of the onions, then add even more caramelized onions over the patty. For an extra burst of flavor, drizzle a little onion jus from the pan over everything. Finally, cap it off with the top half of the bun.
6. Serve and Enjoy!
Serve your burgers immediately, garnished with fresh thyme or parsley if you like. These Easy French Onion Burgers are incredibly juicy, flavorful, and sure to become a favorite at your dinner table!

FAQ for Easy French Onion Burgers with Melted Cheese
Can I Use Ground Turkey or Chicken Instead of Beef?
Absolutely! Ground turkey or chicken is a great alternative if you’re looking for a leaner option. Just make sure to season it well, as these meats can be less flavorful than beef.
What If I Don’t Have Balsamic Vinegar?
No worries! If you don’t have balsamic vinegar, you can substitute it with red wine vinegar or apple cider vinegar. They will give a slightly different flavor but will still enhance the sweetness of the onions.
How to Store Leftovers?
Store any leftover burgers in an airtight container in the refrigerator for up to 3 days. To reheat, microwave them gently or warm them on the stovetop until heated through, adding a little moisture if needed.
Can I Make the Caramelized Onions Ahead of Time?
Yes, you can! Caramelized onions can be made in advance and stored in the fridge for up to 5 days. Reheat them in a skillet before adding them to your burgers for that fresh, delicious flavor.
