Recipe Summary
So good and easy to make, the best and such a classic Mushroom Swiss Burger recipe! Simple ingredients make for big taste.
A mushroom Swiss burger should still taste like a burger. This one starts with four well-seasoned ground chuck patties, then adds baby bella mushrooms, melted Swiss cheese, and a two-clove garlic mayo. The mushrooms cook while the grill heats, so dinner stays manageable.
Why This Burger Works
The mushrooms bring butter, thyme, and a splash of white wine to the party. Swiss cheese melts over the beef, and the garlic mayo handles the sauce. Nothing else is fighting for room on the bun.
Two cloves of garlic in one cup of mayonnaise is enough. More isn’t automatically better, especially when raw garlic is involved.
Give the Mushrooms Room
Use a wide skillet and wait for the mushrooms to release their moisture. Once that liquid cooks away, the edges can brown instead of steaming into a wet pile. Crowding the pan makes this harder than it needs to be.
No wine open? Use the same splash of vegetable stock or water. Both are already good options in the recipe notes.
Cook Ground Beef by Temperature
Five minutes per side can be an estimate, but it isn’t a doneness test. Grill heat and patty thickness change the timing.
The USDA recommends cooking ground beef to 160°F. Check through the side of the patty so the thermometer reaches the center, then add the Swiss cheese near the end and let it melt.
No grill? A cast-iron skillet over medium-high heat works. Brown the patties on both sides and use the same 160°F temperature check.
The Garlic Mayo Is the Burger Sauce
This mushroom Swiss burger sauce is just crushed garlic and mayonnaise. It is cool, sharp, and rich enough to stand up to the beef and mushrooms without covering them up.
Use plain mayonnaise when you want a milder burger. The garlic mayo isn’t mandatory, but it is the detail that makes this version feel finished.
What to Serve with a Mushroom Swiss Burger
Keep burger night classic with shoestring French fries or air fryer French fries.
For another beef option, the truffle smash burger goes in a richer direction. The blackened salmon burger is a good change when the grill is already hot.
Mushroom Swiss Burger FAQs
What sauce goes on a mushroom Swiss burger?
Little Figgy uses garlic mayo made with two crushed garlic cloves and one cup of mayonnaise. Plain mayonnaise also works when you want a milder sauce.
How do you keep mushrooms from making the burger soggy?
Cook the mushrooms in a wide skillet until their released liquid evaporates and their edges begin to brown. Assemble the burgers just before serving so the mushrooms don’t sit on the bun.
What temperature should a mushroom Swiss burger reach?
Ground beef should reach 160°F in the center as measured with a food thermometer, according to USDA guidance.
Can you make a mushroom Swiss burger without a grill?
Yes. Cook the patties in a cast-iron skillet over medium-high heat and use the same 160°F internal-temperature check.
Can you make the mushrooms without white wine?
Yes. Use a splash of vegetable stock or water instead.

Ingredients
Method
- Clean, grease, and preheat the grill.
- In a large skillet, heat on medium-high and add the olive oil, and butter. Once the butter has melted, add in your sliced mushrooms and salt and sweat the mushrooms until they start to soften.
- Add in the splash of wine and sprinkle over the thyme leaves and continue to saute for another minute. Set aside until ready to use.
- In a large bowl, using your hands, mix together ground beef, salt, pepper, garlic powder, and Worcestershire sauce or liquid smoke until well combined.
- Form 4 patties that are about 1/2 inch thick (can use a patty press for ease or get your hands in there and free form by hand).
- Grill for about 5–6 minutes on each side as a starting estimate, then check the center with a food thermometer. Ground beef should reach 160°F.
- Top with a slice of Swiss cheese and let melt.
- Mix together the mayonnaise with 2 crushed garlic cloves and keep refrigerated until ready to use.
- Simply top the bottom half of the bun with a juicy hamburger patty (cheese already melted on), add a generous helping of mushrooms. If using the garlic mayo, spread on the top half of the bun and place on top.
