🔪 Preparing the Mushrooms
King oyster mushrooms need a bit of prep to unlock their full potential.
Step 1: Clean the Mushrooms
Use a damp cloth or paper towel to gently wipe any dirt off the mushrooms. Avoid washing under running water, as mushrooms absorb moisture easily, which can impact their texture when grilled.
Step 2: Slice the Mushrooms
Cut the mushrooms into thick slices (about 1/2 inch thick). You can slice them lengthwise for a more “steak-like” look or into thick rounds to resemble scallops—perfect for seafood mushroom recipes.
🥣 Marinade for Grilled Oyster Mushrooms
The marinade infuses the mushrooms with smoky, savory flavor while helping them caramelize on the grill.
Step 3: Make the Marinade
In a bowl, whisk together:
- Aceite de oliva
- Soy sauce or tamari
- Balsamic vinegar
- Minced garlic
- Smoked paprika
- Black pepper
- La sal del mar
- (Optional) maple syrup for a hint of sweetness
Step 4: Marinate the Mushrooms
Place sliced mushrooms in a shallow dish or zip-top bag and pour the marinade over them. Let them marinate for 15–30 minutes. Flip occasionally to ensure every piece is well-coated.
🔥 Tip: If you’re in a hurry, even a quick 10-minute soak can deliver excellent flavor.

🔥 How to Grill King Oyster Mushrooms
Grilling enhances the flavor and texture of king mushrooms like no other cooking method. You can use a charcoal grill, gas grill, cast iron grill pan, or even an oven broiler.
Step 5: Preheat Your Grill
Heat your grill or grill pan over medium-high heat. Lightly oil the surface to prevent sticking.
Step 6: Grill the Mushrooms
Place mushrooms directly on the hot grill. Grill for 3–5 minutes per side, pressing gently to ensure contact and those beautiful grill marks. They should become golden brown and slightly crispy on the outside while remaining juicy inside.
🍋 Optional Glaze: In the last minute of grilling, brush mushrooms with a little leftover marinade for extra flavor.
