Believe it or not, I found a way to make a mushroom and Swiss burger even better. AND it’s so simple!!

All you gotta do is slather it with some black garlic aioli. Hopefully, you didn’t miss my post about this unique and amazing aioli, but in case you did I’ll share a few of the highlights. It’s garlicky, salty, and umami flavored with a touch of sweetness.

Black garlic happens to pair spectacularly with mushrooms, as they are both umami-rich. Know what else pairs well?!?

Mushrooms and Swiss!! I bet you already know that though. It is a tried and true combination after all.

This mushroom and Swiss burger starts with a lightly seasoned one-third pound all-beef patty cooked to your liking, then melted Swiss cheese. It is heaped with plenty of soft and buttery sautéed mushrooms and caramelized onions.

Last but not least, it’s all squeezed between a black garlic aioli slathered brioche bun, which is toasted, providing a little bit of crunch to balance out the juicy burger and tender veggies.

I didn’t think I could like any home-cooked burger more than my bacon hatch chile burger, but this one definitely gives it a run for its money. Give them a try and let me know which one you prefer.

How to make mushroom and swiss burgers w/ black garlic aioli? ( + tips)

Meanwhile, heat a griddle or cast-iron skillet lightly coated with a neutral oil to medium-high heat.

Prepare the burger patties by combining the ground beef, minced garlic, 1 teaspoon of Worcestershire sauce, the onion powder, 1/4 teaspoon of ground black pepper, and 1/4 teaspoon of salt in a medium bowl.

Divide the mixture into three equal portions, form them into 4-inch patties, and gently press down the middle with your thumb. This will help keep the patties flat.

Place the patties in the skillet and cook for four minutes, then flip, top with a slice (or two) of Swiss cheese, and cook an additional 3-6 minutes based on desired doneness. The internal temperature should register 130-135 degrees for a medium-rare burger, 140-145 for medium, 150-155 for medium-well, and 160 for well done.

    Notes

    Black Garlic AiolI

    Ingredients
    2 cloves fresh garlic

    1/4 teaspoon salt

    2 large egg yolks, room temperature

    2 teaspoons white vinegar

    1/2 cup high quality extra-virgin olive oil

    6 cloves black garlic

    1/8 teaspoon ground black pepper

    1. With a mortar and pestle crush the garlic together with the salt. Transfer to bowl of food processor fitted with a steel blade or blender. *If you don't have a mortar and pestle you can skip this step and just throw it in your food processor. (See notes).

    2. Add the egg yolks and white wine vinegar and pulse until combined.

    3. Continue blending while slowly adding extra-virgin olive oil one teaspoon at a time.

    4. Blend until all the oil has been incorporated and desired consistency is produced.

    5. Add the black garlic and black pepper and pulse until combined. Serve immediately or refrigerate for later.


    ***Adding the oil slowly is ESSENTIAL for the emulsification process. Simply put, emulsification is the process of combining (by force) two liquids that don’t want to mix (such as oil and water). If this step is not performed properly the sauce will not come together and you’ll have to begin again, so be patient!! It is not possible to add the oil too slowly, so take your time.
