Ingredients
This recipe makes approximately 4 servings (2 tacos per serving).
For the Grilled Portobello Mushrooms
- 4 large portobello mushroom caps, stems removed and gently cleaned
- 2 tablespoons olive oil
- 2 tablespoons soy sauce (or tamari for gluten-free)
- 1 tablespoon lime juice (freshly squeezed)
- 1 teaspoon chili powder
- ½ teaspoon ground cumin
- ½ teaspoon garlic powder
- ¼ teaspoon smoked paprika
- Pinch of black pepper
For the Zesty Cabbage Slaw
- 2 cups shredded red cabbage
- 1 cup shredded green cabbage
- ½ cup shredded carrots
- ¼ cup chopped fresh cilantro
- 2 tablespoons lime juice (freshly squeezed)
- 1 tablespoon olive oil
- ½ teaspoon agave nectar or honey (optional, for a touch of sweetness)
- Salt and black pepper to taste
For Assembly and Garnish
- 8 small corn or flour tortillas
- 1 large avocado, sliced or diced
- Optional: crumbled cotija cheese or vegan feta
- Optional: a dollop of sour cream, Greek yogurt, or vegan crema
- Optional: extra lime wedges for serving
- Optional: your favorite hot sauce
Step-by-Step Instructions
-
Step 1: Prepare the Portobello Mushrooms
Gently wipe the portobello mushroom caps clean with a damp paper towel. Carefully remove the stems and use a spoon to scrape out the dark gills from the underside of the caps. This helps them absorb the marinade better and prevents a muddy texture.
Small tip: Removing the gills is optional but recommended for a cleaner taste and appearance.
-
Step 2: Make the Portobello Marinade
In a shallow dish or a large zip-top bag, combine the olive oil, soy sauce, lime juice, chili powder, ground cumin, garlic powder, smoked paprika, and black pepper. Whisk everything together until well combined. This creates a flavorful base for your mushrooms.
-
Step 3: Marinate the Portobellos
Add the cleaned portobello caps to the marinade, ensuring they are fully coated. If using a dish, flip them occasionally. Let them marinate at room temperature for at least 15 minutes, or in the refrigerator for up to 30 minutes. Don’t marinate for too long, as mushrooms can release too much water.
Small tip: While the mushrooms marinate, you can start preparing your slaw ingredients.
-
Step 4: Prepare the Zesty Cabbage Slaw
In a medium bowl, combine the shredded red cabbage, green cabbage, shredded carrots, and chopped fresh cilantro. In a separate small bowl, whisk together the lime juice, olive oil, agave nectar (if using), salt, and pepper. Pour the dressing over the cabbage mixture and toss well to combine. Taste and adjust seasoning as needed.
-
Step 5: Preheat the Grill
Preheat your outdoor grill to medium-high heat. If using a grill pan indoors, heat it over medium-high heat until hot. Lightly oil the grill grates or pan to prevent sticking. A well-oiled surface ensures your mushrooms get those beautiful grill marks.
-
Step 6: Grill the Portobello Mushrooms
Place the marinated portobello caps gill-side down on the hot grill. Grill for 4-6 minutes per side, or until they are tender and have nice char marks. The exact time will depend on your grill and the thickness of the mushrooms. They should be juicy and slightly softened.
Small tip: Avoid pressing down on the mushrooms while grilling, as this can squeeze out their flavorful juices.
-
Step 7: Warm the Tortillas
While the mushrooms are grilling, warm your tortillas. You can do this directly on the grill for 30 seconds per side, in a dry skillet, or wrapped in a damp paper towel and microwaved for 30 seconds. Warm tortillas are more pliable and delicious.
-
Step 8: Slice and Assemble the Tacos
Once the portobellos are grilled, remove them from the heat and let them rest for a minute. Slice each mushroom cap into ½-inch strips. To assemble, take a warm tortilla, add a generous spoonful of the zesty cabbage slaw, top with several slices of grilled portobello, and finish with avocado slices. Add any optional garnishes like cotija cheese, crema, or hot sauce.
Small tip: For extra flavor, you can drizzle a little extra lime juice over the assembled tacos before serving.
Tips & Variations
- Gluten-Free Option: Ensure you use tamari instead of soy sauce for the marinade and always opt for corn tortillas. Most brands of corn tortillas are naturally gluten-free, but always check the label.
- Vegan or Vegetarian Option: This recipe is already naturally vegan and vegetarian! Just be sure to use vegan sour cream or crema if you opt for those garnishes, and skip the cotija cheese or use a vegan feta alternative.
- Add More Vegetables or Protein: Boost the veggie power by adding grilled bell pepper strips, corn, or black beans to your tacos. For an extra protein kick, crumbled grilled halloumi or seasoned tofu would be delicious additions.
- Make it Spicy: For a fiery kick, add a pinch of cayenne pepper or a teaspoon of sriracha to the portobello marinade. You can also finely dice a jalapeño or serrano pepper and add it to the slaw, or drizzle your favorite hot sauce generously over the finished tacos.
- Creamy Avocado Sauce: Instead of plain avocado slices, blend one avocado with 2 tablespoons of lime juice, a handful of cilantro, a small garlic clove, and a splash of water until smooth and creamy. This makes a fantastic drizzle for your tacos!

Health Benefits
These Grilled Portobello Tacos are not just delicious; they’re packed with wonderful health benefits from their wholesome ingredients.
Portobello mushrooms are a fantastic meat substitute, offering a meaty texture without the saturated fat. They are a good source of B vitamins, like riboflavin and niacin, which are essential for energy metabolism. Mushrooms also provide selenium, a powerful antioxidant that supports immune health.
The vibrant cabbage slaw is a powerhouse of nutrition. Cabbage is rich in Vitamin C, boosting your immune system, and Vitamin K, crucial for blood clotting and bone health. It’s also an excellent source of dietary fiber, promoting healthy digestion and satiety.
Lime juice, a star in both the marinade and slaw, adds a zesty flavor and a significant dose of Vitamin C. This vitamin is vital for skin health, iron absorption, and overall immune function. It also adds a refreshing brightness to the dish.
Avocado contributes healthy monounsaturated fats, which are good for heart health and can help lower bad cholesterol. It’s also loaded with potassium, more than a banana, which is important for maintaining healthy blood pressure, and provides fiber for digestive wellness.
Serving Suggestions
- Classic Sides: Serve these tacos with a side of fluffy cilantro-lime rice, a bowl of seasoned black beans, or a fresh corn salad for a complete meal.
- As a Main Dish: These hearty tacos are substantial enough to be the star of your meal. Offer a variety of toppings like salsa, guacamole, or pickled red onions to let everyone customize their plate.
- Meal Prep Ideas: Prepare the portobello marinade and slaw dressing ahead of time. You can marinate the mushrooms the night before (for a maximum of 12 hours) and chop the slaw veggies. Store components separately and combine just before grilling and serving for ultimate freshness.
Storage Tips
Leftover grilled portobello mushrooms and cabbage slaw can be stored separately in airtight containers in the refrigerator for up to 3-4 days. It is not recommended to freeze the assembled tacos, as the textures of the slaw and tortillas will suffer. To reheat the mushrooms, gently warm them in a skillet over medium heat or in the microwave until heated through. Keep the slaw chilled for best results.
