Deconstructed French Onion Burger is a hollowed-out onion stuffed and baked with a ground beef mixture, caramelized onions, and Gruyere cheese. This mouth-watering creation takes a traditional hamburger to a whole new level and will definitely impress your friends and family! For a burger loaded with onions, try my Oklahoma Fried Onion Burger.
Ingredients & Substitutions
Onions: I used yellow onions, but if you prefer sweeter onions, Vidalia onions would also be delicious. This recipe is for onions that are on the smaller side. If you use larger onions, you may need to double the hamburger mixture. One of the best parts of the recipe is that you will use all of the onion. The removed inside onion layers will be diced and caramelized.
Ground Beef: For best results, use ground beef that is made up of 80% lean meat and 20% fat (80/20). This will give the beef the most flavor and moisture. Of course, you could use leaner ground beef if preferred. Or, try ground turkey for a leaner option. Season the beef with hamburger seasoning, garlic powder, pepper, and Worcestershire sauce.
Cheese: Shredded Gruyere cheese is mixed in with the ground beef as well as added to the tops of the stuffed onions. Gruyere cheese adds a rich and nutty flavor to the ground beef. But, you could use your favorite kind of cheese.
What To Serve With Deconstructed French Onion Burgers
There are many side dishes that would work deliciously with these stuffed onions. Here are a few of my favorites:
- Wedge Salad
- Roasted vegetables like asparagus, green beans, carrots, or Brussels sprouts
- Mashed potatoes or cauliflower mashed potatoes
- French fries (I have Air Fryer French Fries, Salt and Vinegar, Garlic Parmesan, and Shoestring fries.)
- Crusty bread like Ciabatta bread
- Craving even more onions? Add a side of onion rings to the table!
Can I Make This Ahead Of Time?
Yes, there are a couple of ways to get a head start with these Deconstructed French Onion Burgers. Prepare the onions a day in advance. Once you hollow out and dice the onions, store them in an airtight container in the refrigerator up to overnight. Stuffing the onions a day in advance is also an option. Cover them before storing them in the refrigerator overnight. Bake them the next day.
How To Store Deconstructed French Onion Burgers
Leftover deconstructed French onion burgers can be stored in the refrigerator in an airtight container. They will last up to 1-2 days. Reheat them in the oven for about 15 minutes, or until heated through at 375°F. They may not look as fresh, but they will still be delicious!
Deconstructed French Onion Burger
- 4 medium yellow onions
- 2 tablespoons unsalted butter
- 3 tablespoons olive oil, divided
- 1 teaspoon kosher salt
- ½ pound ground beef
- 1 ½ teaspoons hamburger seasoning
- ½ teaspoon garlic powder
- ¼ teaspoon black pepper
- ½ teaspoon Worcestershire sauce
- 1 cup (56.5 g) Gruyere cheese, shredded, divided
- Line a sheet pan with parchment paper.
- Cut about ½ inch off the top and bottom of each onion and remove the outer dry papery layer. Use an apple corer to remove the center of the onion.
- With clean hands, remove the inside layers, leaving 2 outer layers of the onion intact. Reserve the removed inside layers of the onion.
- Place the hollowed onions onto the lined sheet pan, leaving about an inch between each.
- Cut the removed inside onion layers into large dice.
- To a large skillet over medium-low heat, add the butter and oil. When hot, add the diced onions and salt. Cook, uncovered, for 50-55 minutes, stirring occasionally, until the onions have softened and turned golden brown. While the onions are caramelizing, prepare the hamburger.
- To a large skillet over medium heat, add the ground beef, hamburger seasoning, garlic powder, pepper, and Worcestershire sauce. Cook until the beef is no longer pink (8-10 minutes). Remove from heat and drain.
- Mix in ¾ cup of cheese and ½ cup of the caramelized onions.
Assembling and Baking
- Preheat the oven to 375°F.
- Spoon an equal amount of the beef mixture into the center of each of the hollowed-out onions.
- Top with the remaining caramelized onions. The stuffing will be overflowing.
- Bake for 35 minutes, or until cooked through and the outer onions are soft.
- Remove from the oven. Top the onions with the remaining ¼ cup cheese.
- Bake for an additional 10 minutes, or until the cheese is hot and bubbly. Serve.

What the Test Kitchen had to say about this recipe:
I love onions, in any shape or form, so this recipe is exciting for me! A juicy flavor-packed burger, packed inside of a soft and sweet onion? Yes, please!
These are fantastic! The seasoned ground beef filling with caramelized onions stands on its own. But, adding it to the hollowed-out onions just makes this as delicious as it is a neat presentation to serve.
This was delicious! Better than I even thought it would be. The filling is so flavorful on it's own and then even better stuffed inside the sweet onion! I didn't even miss the bun!
I could eat these all day. Preparing the onion does take some time, but it is so worth the effort. I enjoy the caramelization that the onions continue to get while baking. I also loved the flavor of the seasoned beef with the cheese. So delicious!
