Key Ingredients & Substitutions
Ground Beef: I recommend using an 80/20 blend for juicy burgers. If you prefer leaner options, a 90/10 blend works too, just be careful not to overcook. For a lighter dish, turkey or plant-based ground meat are great alternatives!
Onions: Yellow onions are perfect for caramelizing. They get nicely sweet when cooked. If you’re in a pinch, white onions are a good substitute, but they can have a sharper taste. Vidalia onions are a lovely choice when in season for extra sweetness.
Cheese: Swiss cheese is classic here, but Gruyère adds a nice nutty flavor. If you’re looking for something more accessible, American cheese or cheddar will work great too! Just make sure it melts well.
Buns: Brioche buns are soft and slightly sweet, making them my favorite. For a healthier option, whole wheat or gluten-free buns are available. Choose what fits your preferences!
How Do You Caramelize Onions Perfectly?
Caramelizing onions adds depth and flavor to your burgers. It’s simple but requires patience! Here’s how to do it right:
- Heat butter and olive oil together in a skillet over medium heat.
- Add your thinly sliced onions and cook gently, stirring occasionally. This slow cooking (15-20 mins) is key to developing those sweet flavors!
- When they start to soften, stir in the brown sugar and balsamic vinegar. This adds an extra layer of sweetness and richness.
- Cook for an additional 2-3 minutes until the onions are sticky and golden brown. Take your time – it’s worth it!
Perfectly caramelized onions can elevate any dish, and they are the star of this burger! Enjoy!
Easy French Onion Burgers With Melted Cheese
Ingredients:
- 1 lb ground beef (80/20 blend for juiciness)
- Salt and black pepper, to taste
- 1 large onion, thinly sliced
- 1 tbsp butter
- 1 tsp olive oil
- 1 tbsp balsamic vinegar

- 4 brioche or soft burger buns
- 2 tbsp mayonnaise (optional, for buns)

How Much Time Will You Need?
This recipe takes about 30 minutes total to prepare and cook. You’ll spend about 15-20 minutes caramelizing the onions and another 10 minutes on the burgers. Quick and easy for a delicious and gourmet meal!
Step-by-Step Instructions:
1. Caramelize the Onions:
In a skillet over medium heat, melt the butter and add the olive oil. Once melted, add the sliced onions. Stir occasionally, letting them cook until they become soft and golden brown — this takes about 15-20 minutes. To enhance the flavor, mix in the brown sugar and balsamic vinegar, and cook for an extra 2-3 minutes until the onions are deeply caramelized and sticky. Remove from the heat and set aside.
2. Prepare the Beef Patties:
While the onions are cooking, shape the ground beef into 4 equal-sized patties. Don’t forget to season both sides with salt and black pepper to taste!
3. Cook the Patties:
Next, heat a grill pan or skillet over medium-high heat. Cook the patties for about 4-5 minutes on each side, or until they are cooked to your liking. In the last minute of cooking, place a slice of cheese on each patty and cover the pan to help the cheese melt faster.
4. Prepare the Buns:
It’s time for the buns! Lightly toast them on the grill or in a toaster for about a minute or two. If you like, spread some mayonnaise on the bottom half of each bun for added flavor.
5. Assemble the Burgers:
To assemble, place each cheeseburger patty on the toasted bottom bun. Layer on the caramelized onions generously. If you want, sprinkle fresh thyme leaves on top for a fragrant touch. Cover with the top bun and drizzle a little extra balsamic glaze from the onions for a beautiful finish.
6. Serve and Enjoy!
Enjoy your delicious burgers immediately! Serve them up with your favorite sides like fries or a salad, and savor the rich, sweet-savory goodness of these Easy French Onion Burgers!
These burgers are perfect for a family dinner, gathering with friends, or simply a special treat for yourself. Enjoy the delicious flavors!
Frequently Asked Questions (FAQ)
Can I Use Ground Turkey Instead of Beef?
Absolutely! Ground turkey is a great substitute for a leaner option. Just be mindful that turkey may require a little more seasoning to enhance the flavor since it’s milder than beef.
How Do I Store Leftover Burgers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. For best results, keep the patties and toppings separate to maintain freshness. Reheat on the stovetop or in the microwave before serving.
Can I Make the Caramelized Onions Ahead of Time?
Definitely! You can make the caramelized onions a day ahead. Just store them in the refrigerator in an airtight container and reheat gently on the stove before assembling your burgers.
What Can I Substitute for the Balsamic Vinegar?
If you don’t have balsamic vinegar, you can use red wine vinegar or apple cider vinegar for a different flavor. Just keep in mind that the sweetness and richness may differ, so you might want to adjust the brown sugar accordingly.
