These burgers bring all the flavors of French onion soup right to your grill. I love making them on a busy night—they’re quick, tasty, and everyone asks for seconds! 🍔
Key Ingredients & Substitutions
Ground Beef: I suggest using 80/20 ground beef for juicy burgers. If you’re looking for leaner options, you can use turkey or plant-based alternatives. Just keep in mind that leaner meat may require careful cooking to avoid dryness.
Onions: Yellow onions are best for caramelizing due to their sweetness. If you need a swap, try sweet onions like Vidalia or even red onions for a bolder flavor. Just remember, each type will give a different taste!
Swiss Cheese: Swiss cheese melts beautifully and complements the onions perfectly. Gruyère is my top choice for a richer flavor. If you want to mix it up, try provolone or even sharp cheddar for a different kick!
Buns: Brioche buns add a nice sweetness and softness. If you want a healthier option, whole grain or lettuce wraps could work well too, just adjust your cooking time since those won’t require toasting.
How Do You Perfectly Caramelize Onions?
Caramelizing onions can take time but is well worth it! This process brings out their natural sweetness, enhancing your burgers.
- Start with medium-low heat and use a mix of butter and oil to prevent burning.
- Add sliced onions and stir every few minutes. Patience is key—let them slowly caramelize for 30-40 minutes.
- If you wish, sprinkle a little sugar to boost their sweetness and deepen the color.
- Deglaze the pan with beef broth towards the end for extra flavor, scraping up those tasty bits stuck to the pan.
This step adds incredible flavor and takes your cheeseburgers to the next level! Enjoy the process, and get ready for those fantastic smells in your kitchen!

Ingredients You’ll Need:
- 1 lb ground beef (preferably 80/20 for juiciness)
- Salt and freshly ground black pepper, to taste
- 2 large yellow onions, thinly sliced
- 2 tbsp unsalted butter
- 1 tbsp olive oil
- 1 tbsp sugar (optional, to aid caramelization)

- 4 slices of Swiss cheese (or Gruyère for more authentic flavor)
- 4 hamburger buns, toasted
- 1 tbsp Worcestershire sauce (optional, for extra savoriness)
How Much Time Will You Need?
This recipe will take approximately 10 minutes of prep time and about 40 minutes of cooking time. The overall total is around 50 minutes, making your burgers ready to enjoy in no time! Perfect for a delightful dinner or a weekend cookout!
Step-by-Step Instructions:
1. Caramelize the Onions:
Start by melting the butter with the olive oil in a large skillet over medium-low heat. Once melted, add the thinly sliced onions. Cook slowly, stirring frequently, until the onions are soft and beautifully caramelized. This will take about 30-40 minutes. For a little extra sweetness, stir in the sugar halfway through cooking, if you wish. Near the end, add the beef broth to deglaze the skillet and mix in all the delicious bits that have stuck to the bottom. Set the caramelized onions aside once done.
2. Form the Burger Patties:
While the onions are cooking, shape the ground beef into 4 equal-sized burger patties. Make sure to create a slight indentation in the center of each patty to prevent it from puffing up while cooking. Season both sides generously with salt and black pepper. This will enhance the flavor of the meat.
3. Cook the Burgers:
Heat up your grill or skillet over medium-high heat. Once hot, add the burger patties and cook for about 3-4 minutes on one side until nicely browned. Flip the patties over and place a slice of cheese on each as they finish cooking. Let them cook for another 3-4 minutes—until the cheese melts and the patties are cooked to your desired doneness.
4. Assemble the Burgers:
Take the toasted hamburger buns and place the cheesy burger patties on the bottom half. Load on the caramelized onions, really piling them on for that French onion flavor. If there’s any leftover onion sauce in the skillet, drizzle it over the onions for extra deliciousness.
5. Top with the Buns:
Finally, place the top buns on each burger and serve immediately. Enjoy these tasty Cheesy French Onion Burgers with your favorite sides!
And there you have it! A savory and cheesy delight that perfectly captures the rich, comforting flavors of French onion soup right in a burger! Enjoy every bite!
FAQ for Cheesy French Onion Burgers
Can I use a leaner ground beef for these burgers?
Yes, you can use lean ground beef, but it might result in drier burgers since leaner cuts have less fat. If you choose to go lean, consider adding a little olive oil or cooking it to a lower doneness to retain moisture.
What can I substitute for Swiss cheese?
If you don’t have Swiss cheese, you can use Gruyère for a richer flavor or try provolone, Monterey Jack, or even sharp cheddar for a twist on flavors. Just make sure whatever cheese you pick melts nicely!
How do I store leftovers? Can I reheat them?
Store any leftover burgers in an airtight container in the fridge for up to 2-3 days. To reheat, place the patties and onions in a skillet over medium heat until warmed through, or microwave them briefly, covered with a damp paper towel to retain moisture. Just be careful not to overheat, as it can dry them out!
Can I make the caramelized onions ahead of time?
Absolutely! You can caramelize the onions a day in advance. Just refrigerate them in an airtight container and reheat them gently on the stove or microwave before serving. This will save time on the day you plan to make the burgers!
