If I feel the need for a burger, I usually go for something familiar like a smash burger. But if I feel the urge to try something more fulfilling, I always make a stop at a Mushroom Swiss Burger.

The Swiss burger may have originated in the United States, but when I ate one at a Burger Brothers restaurant in Zurich, Switzerland, a few years ago, it was the most delicious thing I’ve ever eaten. It was a burger unlike any other, with gooey Emmentaler Swiss cheese that was full of flavor but still classy.

And I’ll tell you, as a self-proclaimed burger expert, I don’t eat average burgers. That’s why I had to make this mouth-watering masterpiece at home, with its unrivaled combination of mushrooms, Swiss cheese, and brioche buns.

Mushroom Swiss Burger

This is the perfect mushroom Swiss burger. You can make homemade burgers by grilling them and adding a slice of Swiss Cheese and sauteed mushrooms to the top. But we go beyond and add a thick mushroom sauce and heavenly Swiss Cheese. Isn’t it amazing to see the Swiss cheese just beginning to drip off the edges in anticipation of your first bite?  

It takes more than just putting a burger on a brioche bun and adding cheese to make a gourmet-quality burger. Details are what make a burger different from a regular burger. Make sure you take your time when making the burger. Saute the mushrooms, toast the buns, and melt the cheese. Although we only use simple ingredients for this recipe, it is easy to make a perfect burger.

But let’s be honest: sometimes you just want to treat yourself, especially after burning off a lot of calories. And I did that while climbing and skiing in the Swiss Alps. This burger was the perfect prize for all that hard work.

Mushroom Swiss Burger Sauce

For Swiss burger sauce or gravy, the secret is sauteed onions and mushrooms. This amazing mixture of flavors takes only a few minutes to prepare.

Sauteed onions and mushrooms can be used in many other delicious beef recipes. Try pairing them with, Oven-baked chuck roast or Garlic Butter Steak Bites.

Ingredients

Onions for Swiss burger

• 4 sliced onions (yellow or sweet)
• 3 TBSP of unsalted butter
• Water
• Pinch of salt

Mushrooms for Swiss burger

• 1 TBSP of butter
• 9 oz of sliced crimini mushrooms
• 1 Minced garlic clove
• salt and pepper

For the burgers

• 1 1/2 lb of Ground beef
• 1 tsp of burger seasoning
• 5 slices of Swiss cheese (I use Swiss Emmental cheese)
• Brioche buns
• Mayonnaise (optional)

Mushroom Swiss Burger Recipe Instructions

For the onions:

• Add the butter and onions to a large skillet (you can also use a pan). Cover the skillet and let the butter and onions cook on medium. Cook for about 7-9 minutes, occasionally stirring until the onions begin to brown.
• Cover the pan and cook on low heat until the onions turn golden brown. To deglaze the pan, add some water to the onions if they stick to the bottom. This is usually done 2-3 times.
• The onions can be removed in 30 minutes or cooked for up to an hour. As you cook them, they will become softer and really sweet. They are ready to go after around 40-45 minutes. Salt to your liking.

For the mushrooms:

• Melt the butter on medium heat, using a skillet, and add in the mushrooms.
• Cook them for 4-5 minutes, with no stirring. They should be cooked until they are golden brown on the other side.
• Now you can flip the mushrooms and cook the other side until golden brown. Sauté the garlic for about 20-30 seconds, and then season with salt.

For the burgers:

• Form the patties into even-sized balls and then press the patties into a flat shape with your palm. Using your thumb, press into the middle of each patty, then sprinkle both with burger seasoning.
• Heat up your skillet on medium heat. Cook the patties until golden brown on the bottom. This usually takes about 4-5 minutes. Turn the patties over and continue cooking for 3-4 minutes more. You can use a meat thermometer to check; they should reach 145°F for medium cooked and 160°F for well done. For the final 2 minutes, add the cheese, so it melts nicely.
• Spread the mayonnaise (if desired) on the brioche buns before assembling. Each one should be topped with caramelized onions first, then mushrooms.
• You can add some salad if you like. Enjoy!

Frequently Asked Questions

What do I do if my hamburger sticks to the pan?

If your burger sticks to the pan, it is not ready for flipping. Give it another minute, and then flip it again.

Can I use a different cheese?

Well, you could, and it will taste good, but it won’t be the original recipe! Remember that Switzerland is famous for cheese, as much as France is. You can mix it up with cheeses like Gruyere and White Cheddar.

Can I use lean ground meat?

Yes! You can make a leaner burger by using a 90/10 mix instead of 80/20. You can check the full list of Burger blends in this article.

Is this keto-friendly?

This grilled burger recipe can be used as a keto-friendly option, provided you skip the bun. We know that buns are full of carbohydrates.

Gluten-Free Burgers

Make this mushroom Swiss Burger gluten-free by making sure that the buns used are gluten-free buns.

Assembling Caramelized Onion and Mushroom Swiss Burger

Assembling the burgers was always my favorite part of the whole process when making burgers.

Buns. A good brioche bun is my favorite for burgers. You can choose whatever makes your heart sing. You can sprinkle it with poppy seeds, sesame seeds, or anything you desire. You can toast the buns; in fact, I highly approve of that. You can choose gluten-free buns or some keto-friendly options.

You can make your burger stand out by brushing the buns with oil/melted butter. In 2-3 minutes, they should be warm and golden brown.

Add your cooked patties (drippings with cheese) to a bun and slather in mayo.

Layer mushrooms and caramelized onions on a bun. Then, top it with another bun, which is also covered in mayo. I don’t skip the sauce, even for burgers with all these delicious toppings. It brings everything together!
