Ingredients

Scale

Vegetables

  • 4 large Portobello mushrooms, sliced
  • 1 red bell pepper, sliced
  • 1 yellow bell pepper, sliced
  • 1 large onion, sliced

Seasonings and Marinade

  • 3 tablespoons olive oil
  • 2 tablespoons lime juice
  • 1 tablespoon chili powder
  • 1 teaspoon cumin
  • 1 teaspoon smoked paprika
  • ½ teaspoon garlic powder
  • Salt and pepper, to taste

To Serve

  • 8 small flour or corn tortillas
  • Fresh cilantro, for garnish
  • Avocado or guacamole, for serving
  • Salsa, for serving

Instructions

  1. Prepare the Vegetables: Slice the Portobello mushrooms, red and yellow bell peppers, and the large onion into thin, even strips to ensure quick and uniform cooking.
  2. Marinate: In a large mixing bowl, combine the sliced mushrooms, bell peppers, and onion. Add the olive oil, lime juice, chili powder, cumin, smoked paprika, garlic powder, salt, and pepper. Toss everything together until the vegetables are evenly coated with the marinade.
  3. Heat the Pan: Preheat a large skillet over medium-high heat until hot but not smoking, which will help achieve a good sear on the vegetables.
  4. Cook the Vegetables: Add the marinated vegetable mixture to the skillet. Sauté for about 10-12 minutes, stirring occasionally, until the mushrooms become tender and the peppers and onions have a slight char for enhanced flavor.
  5. Warm the Tortillas: While the vegetables cook, warm the tortillas in a separate pan over low heat or microwave them for 20-30 seconds until they are soft and pliable.
  6. Assemble Fajitas: Remove the skillet from heat and spoon the cooked mushroom and vegetable mixture evenly onto each warm tortilla.
  7. Add Toppings: Garnish the fajitas with fresh cilantro and serve alongside creamy avocado or guacamole and tangy salsa to enhance the flavors and add freshness.
  8. Serve Immediately: Enjoy these Vegan Portobello Mushroom Fajitas warm, allowing guests to customize with additional toppings as desired.

Notes

  • For gluten-free options, use corn tortillas instead of flour tortillas.
  • Feel free to add other fajita vegetables like sliced zucchini or jalapeños for extra flavor.
  • Use fresh lime juice for the best tang and flavor.
  • This recipe is perfect for meal prep; store cooked vegetables and tortillas separately and reheat before serving.
  • Adjust the chili powder and spices to taste if you prefer milder or spicier fajitas.
