French Onion Soup Burgers

This recipe for French onion soup burgers has a bunch of steps, but luckily they’re all easy and it’s more than worth it once you taste them.  Depending on how fast you can slice onions and if you can multitask, it could take anywhere from 20 minutes to 40 minutes from start to finish.  It took me roughly 30 because it was the first time I had made them.   The work is more than worth it once you taste them.  I guarantee you.

Below you’ll find out how to make them and a couple tips on making them lower in calories if you’re watching your weight.  They’re still as good, but a little bit better for you.

Total Time35 mins
Course: Main Course
Cuisine: American, French
Servings: 2 people


  • 1/2 lb ground beef 1/4 lb per person is good
  • 2 slices Gruyere cheese (you can substitute with any cheese of your choice)
  • 2 buns
  • 1 pinch nutmeg
  • 1 tbsp flour
  • 1 bunch thyme
  • 1 medium yellow onion thinly sliced
  • 1/4 cup beef stock
  • 1 tbsp butter (you can use a reduced calorie butter substitute)
  • 1 tsp sugar (you can use a calorie free sweetener)
  • 1/2 cup milk (you can use skim for a lower calorie option)
  • olive oil extra virgin
  • sea salt
  • ground black pepper


  • This recipe is done in multiple steps. Below you'll find the three parts broken out. You can try to do all three at once or you can do them one at a time, either way it'll end up working out.

Make a Béchamel Sauce

  • The sauce may sound fancy, but it's only a few ingredients and is basically gravy. Start by melting the butter on medium and toss in the flower. Mix the two together using a whisk and as it thickens, start adding the milk slowly while whisking it. Once it's mixed together, toss in the nutmeg and a pinch of sea salt and black pepper. Then you're done.

Cook the Onions

  • Heat a drizzle of extra virgin olive oil on medium high heat and then toss in your onions and thyme. Once they've caramelized (about 7 or 8 minutes), pour in the beef stock and the sugar and let it reduce over medium heat. Now remove the thyme stems from the pan and place the onions on the side.

Cook the Burgers & Melt the Cheese

  • Now split your ground beef into even patties and season with sea salt and pepper. Add a drizzle of extra virgin olive oil to a pan on medium high heat and cook the burgers for about 5 minutes on each side or until you're about 1 minute away from your favorite temperature. Once you're about a minute away from being done, add the Gruyere cheese to the top and cover it so that the cheese melts.
  • While the cheese is melting, you can either toast your buns or begin building the burger. Start by adding the béchamel sauce to the top and bottom of the bun and then when your burger is ready, place the burger on the bottom half. Now add the onions on top and get ready to enjoy an awesome burger!
