This week, I knew I wanted to make something with truffles, I just didn't know what. Truffles are a type of edible mushroom that has a rich and savory flavor like nothing else you have ever tasted. Whenever I eat something with truffle in it, I lose my mind (in a good way). They are the ultimate comfort food ingredient, so I was overwhelmed with all of the options I could make with truffles. The idea for these burgers hit me after a trip to Hopdoddy and being pleasantly surprised by the veggie burger menu. I realized that it is RARE to come across a decadent and delicious veggie burger these days... especially in Texas.
So I decided to live out my fantasy of veggie truffle sliders. I chose sliders, because they are cuter (duh). To enhance this recipe, I decided to keep this burger monochromatic and use ingredients that had a white/brown color. I think these ingredients vibe really well together and provide a flavor of total comfort.
Though this recipe tastes expensive, the only thing that costs a pretty penny is the truffle oil. I decided to use truffle oil instead of a whole truffle since it is easier to find and simpler to use. Also a little bit of oil adds a ton of flavor. Yes, anything truffle will be expensive, but I recommend buying it anyways. It adds so much to any recipe and just a little bottle should last you a long time. I purchased my truffle oil here.
The only condiment I used on these sliders was Vegenaise. Vegenaise is exactly what it sounds like: "Vegan Mayonnaise". Its main ingredient is Canola oil and also includes soy protein, apple cider vinegar, and lemon juice. It is quite expensive as well. So if you aren't vegan, regular mayonnaise will work just fine with this recipe. You can find Vegenaise here.
For the slider buns, I used Sweet Hawaiin Dinner Rolls because, why not. I can eat these rolls by themselves (which I did with half of the bag). They add a certain sweetness to the sliders that help balance out all the savory and richness going on in the patty. The ingredients in these rolls seem to be all vegan. However, double check and do some research because I could be overlooking something since I am not strictly vegan.
Caramelizing Onions: For a garnish, I decided to caramelize half of a white onion. To caramelize, it is usually recommended that you sauté the onion on a medium heat slowly so they don't develop any color. However, I decided to make my onions a bit on the crispier side. I did this by using a higher heat for a faster amount of time. I did this since the bean patties for the sliders are chewy. I wanted to add a little bit of crunch to the sliders.
*Pro Tip: If you want to add some acidity to this burger, add pickles, pickled onions, or some white vinegar!
White Bean Truffle Sliders
Yield: 4-6 Sliders
Prep Time: 30 minutes | Cook Time: 10 minutes
1 can white navy beans, drained and rinsed
1 can cannellini beans, drained and rinsed
1 cup panko bread crumbs
1 tablespoon white truffle oil
1 head of roasted garlic (directions on how to roast garlic below in instructions section)
1 tablespoon olive oil
1 white onion (1/2 cut into a small dice and reserved for the patty mixture and 1/2 cut in a sauté slice and caramelized and set aside for garnish)
1 pinch of salt
1/4 cup canola oil
1/4 cup of Plant Based Parmesan
6 Hawaiin rolls, cut in half and toasted
1/4 cup of Vegenaise
Heat your oven to 425 degrees Fahrenheit. Cut the tip of the garlic head off and place in in the center of a piece of foil. Pour 1 tablespoon of olive oil over the open part of the garlic and wrap the foil around the garlic. Place in the oven for 30 minutes or until garlic bulbs are golden brown.
While you are waiting for the garlic to roast, coat a large pan with oil and caramelize your onions, about 10 minutes.
Clean out your pan and re-coat it with fresh oil. Slightly toast the inside of the Hawaiin rolls until they are golden brown.
Spread Vegenaise on each side of the toasted Hawaiin rolls. Set aside for later.
In a medium bowl, combine beans, bread crumbs, small dice onion, truffle oil, roasted garlic and salt. Mix with your hands or a potato masher until well combined, leaving a few beans whole for texture.
Shape the mixture into 3 oz. sized patties. Add the rest of the oil to the pan and heat to a medium high. Place your patties in the pan and sear each side, about 4 minutes a side.
To make your burger, layer a bun with a slider patty, caramelized onions, and top it off with another toasted bun! Enjoy!
