Fully cooked Lion's Mane Steak on a plate
Introduction by: Isabella Mead

The sound of a sizzling steak combined with the warm, savory aroma of a rich marinade is enough to make anyone’s mouth water. And you can experience the same with a vegetarian-friendly Lion’s Mane Steak—made with lion’s mane mushroom. 

RELATED: The Best Plant-Based Proteins (That Are Also Paleo) 

Mushrooms make a great swap for any steak dish because they are lower in calories, contain significantly more potassium, less sodium, and a wider variety of vitamins and minerals.1,2 In general, mushrooms are high in fiber, which supports gut health and stimulates beneficial gut bacteria.3 Having healthy digestive function also directly correlates with a healthy immune system. 

To make this Lion’s Mane Steak extra crispy and tender, we fried each side and flattened the mushroom down. We used a griddle weight, but a small, flat lid would also work well to press on the mushroom. When flattening, be sure to watch out for griddle spit. As the mushroom releases water, it will react with the oil and can fly out of the pan and burn your skin.  

TIPS 

  • If you have beetroot powder, you can mix ¼ teaspoon of it with ¼ cup water to get the same result as beetroot juice.
