Ingredients

Mushrooms

  • 10oz Black Oyster mushrooms, shredded with a fork
  • 1 tbsp tamari or coconut aminos
  • 1 tsp smoked paprika
  • ½ tsp garlic powder
  • ½ tsp onion powder
  • ¼ tsp ground black pepper
  • Pinch of sea salt
  • 1 tsp maple syrup (optional, for balance)
  • 1 tsp apple cider vinegar

BBQ Sauce

  • ½ cup unsweetened tomato paste
  • 2 tbsp date syrup or maple syrup
  • 1 tbsp apple cider vinegar
  • 1 tbsp tamari or coconut aminos
  • 1 tsp smoked paprika
  • ½ tsp ground mustard
  • 1 clove garlic, minced
  • ¼ tsp cayenne (optional)
  • Water, to thin (about 2–4 tbsp)

For Serving

  • Whole grain or sprouted buns, lightly toasted
  • Shredded red cabbage, pickled onions, or pickles
  • Fresh cilantro or parsley (optional)
  • Scoop of avocado (optional)

Instructions

Shred and prep the mushrooms

  • Use a fork to shred the mushroom stems lengthwise. Thinly slice the caps.
  • Cook mushrooms in a skillet over medium heat until they release moisture. Stir occasionally.

Make the BBQ sauce

  • In a bowl, whisk together all BBQ sauce ingredients.
  • Adjust seasoning and consistency to taste. (add water to thin)

Season and marinate

  • Toss raw mushrooms with the BBQ sauce.
  • Let sit for 10–15 minutes to absorb flavor.
  • (overnight is even better, if you're patient)

Sauté

  • Heat a nonstick or cast iron skillet over medium-high.
  • Add mushrooms and sauté until desired texture. Flip often.
  • (Optional: Add a splash of broth or water if needed. Add oil only after mushrooms have sweated, if using.)

Assemble the sandwich

  • Layer BBQ mushrooms onto toasted buns.
  • Top with cabbage, pickles, avocado, and fresh herbs if desired.
  • Serve hot and savor the smoky umami punch.
