Lion’s Mane Mushroom Steaks



  • 3 large lion’s mane mushrooms 
  • 1.5 teaspoons onion powder 
  • 1.5 teaspoons poultry seasoning 
  • 3 tablespoons canola oil and 2 TBSP olive oil mixed 
  • Salt and pepper 
  • 3 tablespoons vegan butter 
  • Fresh herbs for garnish 


  1. Preheat oven to 425°F 
  2. Trim the bottom of the mushrooms just enough so they sit flat. 
  3. Heat a large heavy ovenproof skillet or cast-iron skillet over medium-high heat. 
  4. When hot, swirl in enough oil to coat the bottom. Add mushroom stems side down and let them cook for 1-2 minutes to soften.  
  5. Add a second heavy skillet on top of mushrooms and cook for 5-6 minutes. (This helps release the water in the mushrooms so that a meaty texture is created.)  
  6. To help the mushrooms sear and brown, wipe off any water from the bottom of the top pan.  
  7. Flip the mushrooms and add a little more oil, shaking the pan to get the mushrooms coated.  
  8. Press firmly until the mushrooms are seared, browned and pressed to half their original thickness, another 5 minutes or so. 
  9. Add onion powder and poultry seasoning together and sprinkle some over the mushrooms with salt and pepper.  
  10. Flip and cook for another 2 minutes, adding a little more oil for browning and flavor.  
  11. Season the top side and flip again to cook the seasons side, continuing to press and sear until both sides are charred and crispy. It should be ¾ thick when done. 
  12. When done, place a pan of mushrooms in the oven for 10 minutes. 
  13. Remove mushrooms from oven and from the pan, set aside. 
  14. Put pan over medium heat, add butter, stirring and scraping all the good bits off the bottom of the pan. 
  15. Slice the mushroom steaks thin and fan out slices on a plate.  
  16. Spoon the pan butter sauce on top and garnish with parsley or thyme.
