Ingredient Notes

Let’s walk through some of the ingredients in this incredible burger.

You will need to use ground chuck because you want beef that has a fair amount of fat in it. I like to use ground chuck as it is about 20% fat. The fat makes the beef juicy. If you use ground round, you just aren’t going to get the same result. Any more fat and the beef flavor won’t come through.

This burger is a truffle mushroom swiss. You will need to use truffle oil to flavor up your mayonnaise.

Most grocery stores sell inexpensive truffle oil. You can also purchase truffle oil online. Since we are mixing it with mayonnaise I would not spend a lot of money on it.

Finally, we will use an egg bun. If they are not available at your grocery store, you can use brioche or potato buns.

How to Make Mushroom Swiss Burger with Truffle Mayo

1. Combine salt, pepper, and seasoning salt to make a seasoning mix for the burgers and mushrooms and onions.
2. Prepare the truffle mayonnaise by mixing together mayo and truffle oil.
3. Cook the mushrooms and onions in butter until they are softened and slightly browned. Season them while they are cooking.
4. Divide the ground beef into 8 equal portions and use your hands to press them into balls.
5. Cook the beef balls by smashing them into a hot skillet and seasoning them while cooking.
6. Flip over the burger patties in the skillet, season them again, and top them with Swiss cheese.
7. Spread truffle mayonnaise on top and bottom buns.
8. Build the burger by placing a burger with cheese on the bottom bun, then mushrooms and onions, another burger with cheese, more mushrooms and onions, and finally the top bun.

How to Make Smashed Burgers

To smash the burgers onto the grill or skillet you may want to wrap a large can or brick with foil or use another skillet to smash the burger into the grill.

You can also use two spatulas and really press the meat onto the grill.

I like to cook these burgers in a cast iron skillet. Iron skillets are ideal for browning meat, as they conduct heat very well.

These burgers will cook rapidly. They will cook in just about 2 or 3 minutes.

I know you are going to love this burger as much as I do. You only need a few key ingredients to make one of the best hamburgers at home.
