Key Ingredients & Substitutions
Ground Beef: I love using an 80/20 blend for a juicy burger, but if you prefer leaner meat, you could opt for 90/10 beef. You can also try turkey or plant-based options for a lighter or vegetarian choice.
Onion: Sliced yellow onions work best here as they caramelize beautifully. If you’re out, red onions can be a sweeter substitute, or shallots offer a milder taste.
Gruyère Cheese: Gruyère is my favorite for its meltiness and flavor. If you can’t find it, Swiss cheese is a great alternative. Cheddar would also work, but it won’t give the same rich taste.
Brioche Buns: Brioche buns add a bit of sweetness and are soft. However, you could use whole wheat buns for a healthier option or gluten-free buns if needed.
How Can I Caramelize Onions Perfectly?
Caramelizing onions adds a rich flavor to your burgers, and it’s all about patience! It’s key to cook them on medium heat, stirring occasionally for even cooking.
- Start by heating olive oil in a large skillet.
- Add sliced onions and a pinch of salt; this helps draw out moisture.
- Cook for around 15-20 minutes until they’re soft and golden. If they start to brown too quickly, lower the heat.
- Adding a splash of beef broth and Worcestershire sauce at the end helps create a lovely glaze.
Remember not to rush this step! Well-caramelized onions can make your burger truly special.

How Much Time Will You Need?
This recipe takes about 30 minutes in total. You’ll spend about 20 minutes preparing and cooking the onions and burgers, plus a few minutes for assembling everything. It’s a quick and satisfying meal that brings a taste of French cuisine home!
Step-by-Step Instructions:
1. Caramelize the Onions:
Begin by heating the olive oil in a large skillet over medium heat. Once the oil is warm, add the sliced onions along with a pinch of salt. Cook the onions, stirring occasionally, for about 15-20 minutes. You want them to become soft and golden brown. This process builds the sweet and rich flavor!
2. Add Flavor to the Onions:
Once the onions are caramelized, stir in the beef broth and Worcestershire sauce. Let this mixture cook for an additional 5 minutes until it thickens slightly. After this, remove the skillet from the heat and set the onions aside.
3. Prepare the Burger Patties:
While you’re caramelizing the onions, take the ground beef and divide it into four equal portions. Shape each portion into a patty and season both sides with salt and pepper for flavor.
4. Cook the Burgers:
In another grill pan or skillet, heat it up to medium-high. Cook the burger patties for about 3-4 minutes on each side, depending on your preferred doneness. In the last minute of cooking, place a slice of Gruyère cheese on each patty. Cover the skillet to help the cheese melt beautifully.
5. Assemble the Burgers:
While the burgers are cooking, lightly toast the brioche buns. On the bottom half of each bun, place the cheesy burger patty, then add a generous scoop of those delicious caramelized onions. Cap it with the top half of the bun.
6. Serve:
Garnish your burgers with fresh thyme or parsley if you like, and enjoy them immediately while they’re warm and full of flavor! These French onion burgers are sure to please everyone at the table!
Enjoy your wonderful creation of French onion burgers!
Can I Use Different Types of Cheese?
Absolutely! If you don’t have Gruyère cheese, Swiss cheese is a great substitute, and you could also try provolone or even cheddar for a different flavor profile. Just keep in mind that the melting qualities will vary slightly, so adjust the cooking time accordingly if needed!
How Do I Make These Burgers Gluten-Free?
To make gluten-free French onion burgers, simply use gluten-free burger buns. You can also make a delicious lettuce wrap for a low-carb option. Ensure the Worcestershire sauce is gluten-free, as some brands contain gluten. Check the label for safe consumption!
Can I Prepare the Caramelized Onions in Advance?
Yes! You can caramelize the onions a day ahead of time. Once cooked, store them in an airtight container in the fridge. Reheat in a skillet over low heat when you’re ready to assemble the burgers, adding a splash of beef broth if they seem too dry.
What’s the Best Way to Store Leftover Burgers?
To store leftovers, pack the burgers (without the buns) in an airtight container and refrigerate for up to 3 days. To reheat, simply microwave for a short time until warmed through, or reheat in a skillet over medium-low heat to keep the patties juicy.
