You don’t need meat to make a killer taco. Meaty portobello mushrooms get marinated in a garlicky spiced soy sauce mixture and then grilled to perfection. Place the mushroom slices in a warm tortilla on top of mashed avocado and top with crunchy slaw, a tangy mango salsa, and pickled onions for taco night!
Ingredient Highlight
Mushrooms! are one of my favorite ingredients to add to vegetarian dishes because they have a meaty texture and an umami-rich flavor. They’re a great source of minerals like selenium, potassium and zinc and are also high in B vitamins.

Prep Time 15 minutes 
Cook Time 15 minutes Ingredients
- 4 portobello mushrooms, woody stems removed about 1-1 ½ lbs
- ¼ cup soy sauce or tamari
- 2 tbsp lime juice
- 2 tbsp olive oil
- 3 cloves garlic, crushed or minced
- 2 tsp ground cumin
- 8 small-medium flour tortillas
- 2 avocados mashed
- Pickle red onions optional
For the salsa:
- 1 ripe mango, cut into small pieces about ¾ cup
- ½ cucumber peeled and cut into small pieces about ¾ cup
- 1 tbsp lime juice
- ¼ tsp kosher salt
For the slaw:
- 3 cups shredded cabbage or use coleslaw mix
- 2 tbsp lime juice
- ½ teaspoon kosher salt
- Protein boost: add some black or pinto beans into the taco or put a fried egg or scrambled eggs on top of the mushrooms.
Instructions
- In a large bowl, whisk together the soy sauce, lime juice, oil, garlic, and cumin. Add the mushrooms and shake them around, making sure to get the marinade on the inside of the caps. Let them marinate for 15-20 minutes.
- Heat one side of your grill to medium-high for at least 10 minutes. Add the mushrooms (stem-side-down) and grill, covered, for 3-5 minutes. Flip and spoon some extra marinade on the inside of the caps, then cover and grill for 3-5 more minutes or until you have nice grill marks. Move the mushrooms to the other side and let them cook, covered, for 5 more minutes (the indirect heat will keep cooking them without burning them).
- Meanwhile, in a medium bowl mix together the salsa ingredients. In a separate bowl, mix together the slaw ingredients.
- Warm up your tortillas and add the mashed avocado down the center. Top that with the mushroom slices and the slaw. Top with salsa and pickle red onions, if using.
