Key Ingredients & Substitutions
Ground Beef: I recommend an 80/20 blend for juicy burgers, but you can use ground turkey or chicken for a leaner option. Just remember, leaner meats tend to be less juicy, so consider adding a bit of oil.
Onions: Yellow onions are sweet and perfect for caramelizing. If you want a sharper flavor, you could substitute with red onions or even shallots, but they will change the flavor profile slightly.
Swiss Cheese: Swiss cheese is my go-to for that classic melted experience, but feel free to swap it with Gruyère for a richer taste or Monterey Jack for a milder option. You could also use a dairy-free cheese if you’re lactose intolerant.
Buns: I love using brioche buns for their buttery flavor, but any burger bun will work! Whole wheat or gluten-free buns are great alternatives, depending on your dietary needs.
How Do I Caramelize Onions Perfectly?
Caramelizing onions is key to elevating your burgers. Here’s how to do it right:
- Start with a medium heat to avoid burning them; patience is key!
- Add butter and olive oil to prevent sticking and for flavor.
- Stir them occasionally, but let them be for a few moments at a time so they have a chance to develop color.
- Sprinkle sugar to enhance sweetness, but be wary of burning; adjust heat if needed.
- Cook for about 25-30 minutes until they’re golden brown and deliciously sweet.
Trust me; the wait is worth it for that rich flavor!

How Much Time Will You Need?
This delicious burger takes about 15-20 minutes for prep and about 30 minutes for cooking. You’ll enjoy tender, caramelized onions, juicy beef patties, and melted cheese in about an hour!
Step-by-Step Instructions:
1. Caramelize the Onions:
In a large skillet, heat the butter and olive oil over medium heat. Once melted and hot, add the sliced onions, then sprinkle with sugar and a pinch of salt. Cook the onions slowly, stirring occasionally. Be patient! This will take about 25-30 minutes until they become deeply golden brown and caramelized. Once done, remove from heat and set aside.
2. Prepare the Burger Patties:
In a mixing bowl, gently combine the ground beef with Worcestershire sauce (if using), and season with salt and pepper. Form the mixture into 4 equal-sized patties, about ¾ inch thick, making a slight indentation in the center of each to prevent puffing while cooking.
3. Cook the Burgers:
Heat a grill pan or skillet over medium-high heat. Cook each patty for about 4 minutes on one side and then flip, cooking for another 4 minutes on the other side until they reach your desired doneness. In the last 1-2 minutes of cooking, place a slice of Swiss cheese on top of each patty and cover loosely with a lid to help melt the cheese.
4. Toast the Buns:
While the burgers are cooking, lightly butter the insides of your burger buns. Toast them on the grill or in a skillet until they are golden and crisp—this adds flavor and helps prevent them from getting soggy.
5. Assemble the Burgers:
Start by placing the burger patty with melted cheese on the bottom bun. Next, add a generous helping of the caramelized onions on top. If you’re feeling adventurous, drizzle a bit of warm beef broth or French onion soup over the onions for an extra punch of flavor!
6. Top and Serve:
Finish your burger by adding the top bun. Optionally, garnish with fresh thyme leaves for a lovely touch. Serve these juicy burgers immediately with your favorite sides—fries or a salad pair nicely!
Enjoy this scrumptious burger that brings the delightful flavor of French onion soup right to your plate!
Frequently Asked Questions (FAQ)
Can I Use Ground Turkey Instead of Beef?
Yes, you can substitute ground turkey for ground beef for a lighter option! Just keep in mind that turkey tends to be drier, so consider adding a little olive oil or a splash of broth to maintain moisture.
How Do I Store Leftover Burgers?
Store any leftover burgers in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm them in a skillet over medium heat or in the microwave, ensuring the cheese gets melty again.
Can I Make the Caramelized Onions Ahead of Time?
Absolutely! Caramelized onions can be prepared ahead of time and stored in the fridge for up to a week. Just reheat them gently in a pan before topping your burgers for optimal flavor.
What Should I Serve with French Onion Burgers?
These burgers pair well with classic sides like French fries, sweet potato fries, or a fresh salad. For a heartier meal, you could also serve them with a side of creamy coleslaw or roasted vegetables!
