This mouthwatering mushroom Swiss burger is smothered in a luxuriously silky mushroom gravy, melted Swiss cheese, and served on a toasted bun. If you love mushroom Swiss burgers, this is a premier restaurant-quality gourmet burger recipe you need to try. I promise one bite will blow your socks off! The "secret sauce" is slathering the burger in this outrageous gravy. Seriously, so good!

I like serving these burgers with oven-baked sweet potato fries, homemade french fries, or hearty steak fries. Each would pair perfectly with this meal.

Mushroom Swiss Burger

This is the ultimate mushroom Swiss burger you've been waiting for. Anyone can grill up homemade burgers and throw a slice of Swiss cheese and a few sautéed mushrooms on top, but we take it a step further by smothering melty Swiss cheese in a thick mushroom gravy. Can't you see it just dripping off the edges in anticipation of your first juicy bite!?!

Making a gourmet-caliber burger is more than just tossing any ol' beef patty on a cheap bun with some cheese. The difference between an average burger and the best burger you've ever had is the details. Take your time to make the patty right, saute the mushrooms, toast the buns, and melt the cheese. We are still only using simple ingredients, but all of these easy steps add up to create burger perfection.

Ingredients and Substitutions

• Ground chuck - You can subsitute 80/20 beef, but it is important not to use lean beef or there will not be enough fat to create a juicy burger. Alternatively, you can go a different direction and use my blended burger recipe, which uses a beef patty blended with a mushroom mixture.
• Swiss cheese - If you are making Swiss mushroom burgers, you kind of need slices of Swiss cheese, right? However, if you have a finicky dinner guest who doesn't like Swiss, use Provolone cheese instead.
• Hamburger buns - You can use your favorite gourmet bun for this burger, however, I am a particularly big fan of mingling the flavors of mushrooms and onions, so I recommend onion buns for this recipe. Brioche buns would be my next choice.

Optional - If you want to add more onion flavor, top the burger off with some caramelized onions.

Mushroom gravy

• Sliced baby bella mushrooms - Baby portobello mushrooms are the best mushrooms for these burgers but you can substitute sliced white button mushrooms too, or even use wild mushrooms.
• Butter 
• All purpose flour
• Low sodium beef broth - Low sodium is important because soy sauce and Worcestershire sauce are both salty.
• Soy sauce
• Worcestershire sauce

This is the same mushroom gravy used for my cube steaks, using my brown gravy recipe as a base with a few notable tweaks. Soy sauce and Worcheshire sauce are added for flavor, but since these additions are quite salty I highly recommend using low sodium beef broth so the gravy doesn't get too salty. You can always add more salt to the mushroom sauce when it finishes cooking if it is needed. I also used 16 ounces of sliced baby bella mushrooms, but you can substitute white mushrooms instead if desired.

How to make burger patties

There are a few important tips to adhere to when making the best burger patties. First, you want to use 80/20 beef, such as ground chuck. It has the perfect fat/meat ratio to ensure your burger is juicy and flavorful. You also want to purchase it freshly ground (where you can still see the strands from the meat grinder), not compacted and stuffed into a plastic tube.

Next, to form the hamburger patty, you want to work it as little as possible. This ensures your patties are exceptionally tender. Break the ground beef into ⅓ pound chunks and press them flat with the bottom of a plate. It isn't necessary to mix and mash them with your hands. The more you work the meat, the tougher your burger becomes.

I highly recommend checking out my homemade burger patty tutorial for detailed tips and tricks to crafting the best restaurant-style burger patties.

Tip: When you know how to make a great burger patty, you don't need any special burger seasoning. Salt and fresh ground black pepper is all you need to allow the burger to take center stage.

How to cook a burger

Though the mushroom gravy is most easily made on the stovetop, your burger patties can be cooked in a skillet or on your grill.

• How to cook burgers in a skillet - Set the skillet over medium heat and add the seasoned burger patty. Cook until the top of the patty begins to darken in color, then flip. Top with cheese and continue cooking until the burger reaches your desired doneness. A well done burger takes approximately 4 minutes per side, depending on the thickness of the patty.
• How to cook burgers on a grill - If using a propane grill set the burner to high. If using charcoal, add hot charcoals to one side of the grill, leaving the other side empty. Grill burgers over the hottest side of the grill, again for approximately 4 minutes per side and only flipping once. If the burger is cooking too fast and starting to burn, lower the heat of the propane grill, or on a charcoal grill move the patty away from the pile of coals.

Tip #1: Never press down on the patty with a spatula. This does not help it cook, it just squeezes out the juices inside the burger, creating an unappetizingly dry burger patty.

Tip #2: You can tell how done the patty is by gently pressing it with your finger while cooking. Raw meat is soft and springy and it gradually gets firmer while it cooks. When the patty is quite firm and does give when pressed, it is well done.
