Brain Food: Lion’s Mane Mushroom Burger

As soon as I walked up to the Flying Saucer Farm stand this week, I knew what I was going to use Clint’s amazing LION’S MANE MUSHROOMS for this week’s burger.

This mushroom weighed half a pound!

Lion’s Mane Mushrooms are literal brain food 🧠

These mushrooms have compounds that stimulate the growth of brain cells. Consumption has been known to protect against the development of Alzheimer’s and dementia.

Additionally, the mushroom’s antioxidant levels are beneficial for anxiety, depression, nervous system injuries, diabetes, and general inflammation!

i wanted to highlight the mushroom’s natural flavors.

So I sliced the mushroom into 1/2″ steaks and started with a sear on medium heat in a dry pan.

The fragile “hairs” brown very nicely.

After browning on both sides, I added olive oil to the pan. I seasoned with black garlic salt, black pepper, and thyme.

The black garlic salt added an extra level of umami to the already flavorful mushroom. Thyme is an absolute classic with mushrooms of any kind!

I was a bit surprised at how much the mushroom steaks shrunk while cooking. I thought a half pound mushroom would be enough for two burgers, but after cooking, it was only enough for one. Keep this in mind when buying at the market!

A few elements are needed for a good caramelized onion

First, it is important to get nice, even onion moons. Cut in half on the pole of the onion, cut off the top and bottom of each half, and take your time to get even slices. The more even surface area will help the onion caramelize faster.

I used Vidalia sweet onions.

Secondly, it is important to take your time to develop the sweet flavors. The caramelization process takes at least 30 minutes if not more. Add a bit of water as the pan starts to stick, and stir every few minutes.

I added a touch of balsamic vinegar right before removing from the pan. This added an extra bit of natural sweetness that pairs really well with any mushroom.

Sometimes, a simple burger is best.

I built this burger with a toasted bun, caramelized onions, seared mushroom, and vegan smoked gouda.

Eat it slow and savor every bite!

I made some spicy Tabasco vegan mayo that I thought about putting on the top bun, but I decided to keep it on the side to eat with sweet potato fries. It was nice to dip the sandwich in the spicy mayo every once in a while, but the mushroom and onion flavors were bold and delicious as is!

Baked sweet potato fries made for an amazing lunch!

Simple, sensational, plant-based bbq is easy!
