The Star of the Grill: An Introduction to Lion’s Mane

Before we start cooking, let’s talk about the unique ingredient that makes these Lion’s Mane Mushroom Steaks possible. Lion’s mane is a stunning mushroom that looks more like a white, shaggy pom-pom or a piece of coral than a typical mushroom.

  • A “Meaty” Texture: The reason lion’s mane is perfect for this application is its unique texture. When cooked, it’s stringy and tender, often compared to lobster or crab meat. By using our pressing technique on the grill, we compress this texture into something remarkably dense, chewy, and steak-like.
  • A Canvas for Flavor: Lion’s mane has a mild, slightly sweet, and savory flavor that is not overpowering. It acts like a sponge, beautifully soaking up the smoky flavor from the grill and the savory notes of your chosen seasonings.

The Secret to a “Meaty” Grilled Mushroom

The most critical technique for perfect Lion’s Mane Mushroom Steaks on the grill is the “press and sear” method. These mushrooms hold a lot of water, and to get a great, steak-like texture, you need to get that water out.

We achieve this by placing the mushrooms on the hot grill grates and using a heavy, flat object to press down firmly. A cast-iron grill press is the ideal tool, but you can easily use a second heavy skillet or even two foil-wrapped bricks. This pressing action does two crucial things:

  1. Expels Moisture: It squeezes out the water, which allows the mushroom to sear and char rather than just steam.
  2. Creates a Dense Texture: It compresses the mushroom from a light sponge into a dense, hearty “steak” with a satisfying, chewy bite.

The Key Ingredients for Your Grilled Mushroom Steaks

Each ingredient in this recipe is chosen to build a deep, smoky, and savory BBQ flavor profile perfect for the grill.

  • Lion’s Mane Mushrooms: Three large, fresh mushrooms will transform into three beautiful steaks.
  • High-Heat Vegetable Oil: An oil with a high smoke point, like canola or avocado oil, is essential for grilling without burning.
  • The Seasoning Blend: A combination of your favorite smoky BBQ seasoning and a savory sage and onion blend creates a multi-layered, delicious crust. If you can’t find a specific sage blend, simply use more BBQ seasoning and add a teaspoon of dried sage.
  • Plant-Based Butter & BBQ Sauce: These are used at the end to create a quick, rich, and delicious pan sauce on the grill’s side burner or a grill-safe pan, making use of all the flavorful bits left behind.

Step-by-Step Guide to Your Grilled Lion’s Mane Mushroom Steaks

This recipe is a fun project that gets you outside at the grill. Follow these detailed steps for a perfect result.

Part 1: The Grilling and Pressing

  1. Prepare the Grill and Mushrooms: Preheat your grill for high, direct heat. Make sure your grill grates are clean. Trim just the very bottom of the mushroom stems so that each one has a flat base to sit on.
  2. The First Sear: Heat a large, heavy, ovenproof skillet (cast iron is perfect) on your grill’s side burner, or directly on the grates if you don’t have a side burner. When the pan is hot, swirl in enough oil to coat the bottom. Place the mushrooms in the pan, stem-sides down, and let them cook for 1-2 minutes to just begin to soften.
  3. The Press: Place a second heavy skillet (or foil-wrapped bricks) directly on top of the mushrooms. Let them cook for another minute. Using heat-proof gloves or tongs, begin to press down firmly on the top weight. You will see a significant amount of water release from the mushrooms.
  4. Continue Grilling: Continue to apply firm pressure, pressing the mushrooms down. To get the best sear, it’s helpful to occasionally remove the top weight and wipe away any accumulated water from its bottom. Swirl a little more oil into the pan as needed to prevent sticking and encourage browning. Grill the first side this way for 5 to 6 minutes until deeply browned and compressed.
  5. Flip and Repeat: Use tongs to flip the mushroom steaks. Add a little more oil to the pan. Place the weight back on top and repeat the pressing process for another 5 minutes, until the second side is well-seared and the mushrooms are less than half their original thickness.

Part 2: Season, Finish, and Make the Sauce

  1. Season the Steaks: While the second side grills, mix your BBQ and sage & onion seasonings together. Sprinkle this blend, along with salt and pepper, over the top side of the mushrooms.
  2. Sear the Seasoning: Flip the steaks one more time to sear the seasoned side for a minute or two. Season the new top side. Your Lion’s Mane Mushroom Steaks should now be beautifully charred, crispy, and compressed.
  3. Finish Cooking: Move the skillet to a cooler, indirect heat zone on your grill (or reduce the flame) and let the steaks cook for another 10 minutes to ensure they are cooked through the center.
  4. Make the Pan Sauce: Remove the finished steaks to a cutting board to rest. Place the hot skillet back over medium heat. Add the plant-based butter, and as it melts, use a spatula to scrape up all the flavorful browned bits from the bottom of the pan. Stir in the BBQ sauce until you have a bubbly, medium-thick pan sauce.

Ingredients

Scale
  • 3 large lion’s mane mushrooms (about 1 lb/450 g total)
  • 2 Tbsp vegetable oil (plus more as needed)
  • 2 Tbsp BBQ seasoning
  • 1 Tbsp Wicked Kitchen Sage & Onion seasoning (or similar)
  • Salt and pepper, to taste
  • 3 Tbsp plant-based butter
  • 4 Tbsp BBQ sauce (Wicked Kitchen or your favorite)
  • Fresh herbs like thyme or parsley, for garnish

Instructions

  1. Preheat the oven to 400°F (200°C) with convection, or 420°F (215°C) without convection.
  2. Trim the very bottom of the mushrooms so each one can sit flat.
  3. Heat a large, heavy, ovenproof skillet (like cast iron) over medium-high heat. Swirl in enough oil to coat the bottom.
  4. Place the mushrooms stem-side down in the hot skillet and cook for 1-2 minutes to soften.
  5. Place a second heavy skillet on top of the mushrooms. Gently press down on the top pan to begin pressing the mushrooms, which will release water. As they cook, apply firmer pressure. Wipe away any water that accumulates on the top pan and add more oil to the bottom pan as needed to help with searing. Continue to press and sear the first side for 5-6 minutes.
  6. Flip the mushrooms. Add a little more oil if needed. Press firmly until the second side is seared and the mushrooms are pressed to less than half their original thickness, about another 5 minutes.
  7. Mix together the BBQ seasoning and sage & onion seasoning. Sprinkle some over the top of the mushrooms, along with salt and pepper. Flip and cook for a minute or two.
  8. Season the new top side, flip again, and continue to press and sear until both sides are slightly charred and crispy.
  9. Place the skillet with the mushrooms in the preheated oven for 10 minutes.
  10. Remove the skillet from the oven. Transfer the mushroom steaks to a cutting board.
  11. Place the skillet back over medium heat. Add the plant-based butter, stirring and scraping the bottom of the pan. Stir in the BBQ sauce to create a pan sauce.
  12. To serve, spoon some of the pan sauce onto plates. Slice the mushroom steaks thinly, fan the slices over the sauce, and garnish with fresh herbs.

Notes

  • This recipe recommends using a heavy, ovenproof skillet like cast iron. A second heavy pan is used as a press.

Frequently Asked Questions (FAQs)

My mushrooms are sticking to the grill pan. What did I do wrong?

This usually means your pan was not hot enough when you first added the mushrooms, or you didn’t use enough oil. Ensure your cast iron pan is thoroughly preheated before the mushrooms touch it.

Can I do this directly on the grill grates instead of in a skillet?

You can, but it’s trickier. You would need a very clean and well-oiled grill grate. Placing the mushrooms directly on the grates makes it harder to create a full, even crust, and you won’t be able to make the delicious pan sauce with all the flavorful drippings at the end. Using a cast-iron skillet on the grill is highly recommended for the best results.

What if I don’t have a grill press or a second cast-iron skillet?

No problem! The key is a heavy, flat, fire-proof object. You can take two standard house bricks, wrap them completely in heavy-duty aluminum foil, and place them on top of the mushrooms. They work perfectly as a grill press.
