What’s better than a burger? A burger that tastes like French onion soup! I love serving these with crispy fries. It’s a meal that makes both my stomach and my heart happy! 😄
Key Ingredients & Substitutions
Ground Beef: I recommend 80/20 ground beef for richness, but you can use leaner cuts if you prefer fewer calories. For a healthier option, try ground turkey or chicken.
Onions: Yellow onions are great for caramelizing due to their sweetness. If you have red or white onions, they work too, but they may bring a different flavor to your burgers.
Cheese: Swiss or Gruyere adds a lovely creaminess. If you can’t find either, feel free to swap in provolone, cheddar, or even a vegan cheese for a plant-based option.
Buns: Any burger bun will do! I love using brioche for its sweetness. You could also opt for whole grain or a gluten-free alternative if necessary.
How Do You Caramelize Onions Perfectly?
Caramelizing onions is key to enhancing their natural sweetness. Start with medium heat to ensure they don’t burn. Here’s how to get that golden color:
- Heat butter and olive oil in your skillet.
- Add sliced onions, stir in sugar to help with caramelization, and cook low and slow.
- Keep stirring every few minutes for about 25-30 minutes until they’re golden brown.
- Add balsamic vinegar or Worcestershire sauce towards the end for extra flavor and cook for another few minutes.
Remember, patience is key! The slow cooking will reward you with deep, rich flavors that complement the burgers beautifully.

How Much Time Will You Need?
This recipe will take about 40 minutes total. This includes roughly 30 minutes for cooking the onions and 10 minutes for preparing the burgers. A delicious meal is just around the corner!
Step-by-Step Instructions:
1. Caramelize the Onions:
In a large skillet, heat the butter and olive oil over medium heat. Add the sliced onions and sprinkle the sugar over them. Stir occasionally and cook for about 25-30 minutes, until the onions are beautifully golden and caramelized. Just before they’re done, stir in the balsamic vinegar or Worcestershire sauce, cooking for another 2 minutes to combine the flavors. Remove from heat and set aside.
2. Prepare the Patties:
While the onions are cooking, divide the ground beef into 4 equal portions and shape each portion into a patty that is about ¾ inch thick. Season both sides generously with salt and black pepper.
3. Cook the Burgers:
Heat a grill or skillet over medium-high heat. Cook the patties for about 4 minutes on one side. Flip the burgers and place a slice of cheese on top of each patty. Continue cooking for another 3-4 minutes, or until the cheese is melted and the burgers are cooked to your desired doneness.
4. Prepare the Buns:
While the burgers are cooking, optionally spread mayonnaise on the toasted buns to add a creamy touch. This step adds a nice balance to the burger!
5. Assemble the Burgers:
On each bottom bun, place a cooked burger patty. Top with a generous amount of caramelized onions!
6. Add Finishing Touches:
Place the top buns over the onions. If desired, drizzle a little of the flavorful onion pan juices from the skillet over the burgers for an extra burst of flavor.
7. Serve Hot:
Garnish with fresh thyme leaves if you’d like, and serve immediately with your favorite sides, such as crispy fries or a garden salad.
Enjoy your delicious Cheesy French Onion Burgers, full of rich flavors and gooey cheese! They are sure to be a hit at your next meal!
