This black garlic mushroom burger has become somewhat of a regular in my household. It starts with a crusty-seared burger topped with white onion, swiss cheese, and then topped with a generous pile of caramelized mushrooms in a black garlic gravy. Each bite is smokey, savory, fatty, and impossible to put down.

The power of black garlic.

We are huge fans of caramelized mushrooms, and the black garlic’s power over me cannot be resisted. Have you tried them yet?

Black garlic is pretty trendy right now and rightfully so. It has significant health benefits, boasting massive antioxidants in addition to traditional benefits from typical garlic.

It’s fermented as well, causing a very complex flavor profile that’s almost difficult to describe. It has a mild garlic flavor, but it’s much sweeter with flavors of balsamic, smokey molasses and tamarind. The combination results in a deep umami flavor, incredibly savory which pairs so well with beef.

How to: Caramelized Mushrooms

There’s quite a few ways to caramelize or sauté mushrooms. The method I use focuses on evaporating the moisture from the mushrooms and replacing it with loads of flavor.  It’s called “sweating” the mushrooms. 

  • To do this you use a high-heat, large pan such as an iron skillet. No oil or fat in the pan is required: the high heat will allow the moisture to evaporate and cause the mushrooms to firm up. 
  • When the liquid is almost gone you can deglaze the pan with beef broth which will be absorbed into the mushroom, creating so much more flavor. It’s a really easy, low-maintenance process too.

Black garlic and caramelized mushrooms both have their own unique properties of being extremely savory. Combined with the help of some cream and butter, you have an ultimate topping for burgers, fries, rice, or even just as a side dish. You can skip the cream and butter if you’re trying to be healthy… but I’m here to share a flavor bomb.

Need Ingredients?

Buying black garlic shouldn’t be a concern if you’re comfortable shopping online. I’d recommend picking it up online which is a very fair price for the ingredient.

You can absolutely make it yourself at home. There are a few different processes that will help you be successful. Read about making your own black garlic here if you’d like. I’m all about crafting my own food and artisan supplies, but I’m not the type to use an appliance for a 2-3 week period at a time.

Simple recipe, let’s get to it.

This black garlic mushroom burger is straight forward and delicious. The recipe below makes for 2 heavily topped burgers, or 4 regular portions, but you might want to prepare for more. Every time we make it I end up doubling it, and still regretting it.

The burgers used are from Omaha Steaks. There’s a bunch of options, but even the Steak Burgers are incredibly delicious. Each portion is individually vacuum sealed in the shape of a patty and it holds it’s form well, making it incredibly easy to pull out of the package, season, and sear right away.

Description

This recipe is meant to create enough toppings for 4 burgers, roughly using 1 Cup of raw mushrooms per serving. This sounds like a lot of mushrooms, but they shrink significantly as you sweat them out on your pan. Feel free to use any types of mushrooms that you like, my recipe uses brown cremini but I’ve also used white and portobello.


Ingredients

Scale
  • 4 Omaha Steaks Burgers
  • 4 pairs of hamburger buns
  • 4 swiss cheese slices
  • white onion, sliced into rings
  • 4 cups brown cremini mushrooms, sliced thin
  • ¼ cup beef stock
  • ½ cup heavy cream
  • 2 tbsp butter
  • 1 ½ tbsp black garlic, mashed
  • 1 tsp fresh thyme leaves
  • 1 tsp dijon mustard
  • ½ tsp black pepper, fresh ground
  • salt to taste

Instructions

  1. Heat up a cast iron skillet to medium high heat.
  2. Season the burgers with pepper & salt, let them rest at room temperature.
  3. Add in the sliced mushrooms, it’s ok if they are crowded, we want them to sweat. Stir the mushrooms to make sure they are sweating out their liquid and not burning. You will see liquid form in the skillet and eventually they will start to brown and firm.
  4. After about 5-6 minutes of sweating, the mushrooms should look darker and moist as the liquid has given off. Season the mushrooms with the thyme and black pepper. Add in the beef broth to deglaze the pan, and stir in the black garlic mash. Keep stirring to incorporate everything together.
  5. Once the liquid is almost gone, quickly add in the butter, cream, and dijon. Stir to incorporate and let it reduce slightly to thicken. Taste, season, adjust.
  6. Remove the mushrooms but do not turn off the skillet. Wipe the pan carefully, and add in a few tablespoons of oil.
  7. The oil will start to ripple after about 2 minutes. Add in the burgers 1 by 1, allowing at least an inch between each one. Press down gently in the center as you place them in the skillet to prevent the middle from swelling. Allow the burgers to crisp up at least 2 minutes before flipping.
  8. Flip, and cook for another 2-3 minutes to desired temperature. This is where I add the optional white onions and top with cheese before removing the burgers from the skillet.
  9. Assemble the burgers and top with the mushroom gravy.

Notes

Don’t skimp out on the mushrooms! You might regret it. Mushrooms shrink significantly while cooking and these are so savory you will want plenty!
