  • 1 red bell pepper (sliced)
  • 1 yellow bell pepper (sliced)
  • 1 green bell pepper (sliced)
  • 1 red onion (small, sliced)
  • 2 tbsps olive oil
  • 2 tbsps lime juice
  • 2 garlic cloves (minced)
  • 1 tsp smoked paprika
  • 1 tsp chili powder
  • ½ tsp cumin
  • ½ tsp oregano
  • ½ tsp salt
  • ¼ tsp black pepper
  • ¼ tsp red pepper flakes (optional for spice)
  • ¼ cup cilantro (fresh, chopped)
  • 1 avocado (sliced)
  • ½ cup salsa or pico de gallo
  • ¼ cup vegan sour cream (optional)
  • Lime wedges

Instructions

  1. Marinade Preparation: Whisk olive oil, lime juice, minced garlic, smoked paprika, chili powder, cumin, oregano, salt, black pepper, and red pepper flakes in a spacious mixing bowl to create a vibrant, aromatic flavor base.
  2. Mushroom Preparation: Slice portobello mushrooms into uniform strips, ensuring consistent thickness for optimal texture and even cooking.
  3. Marinating Process: Coat mushroom strips thoroughly with the prepared marinade, allowing them to rest and absorb the robust flavors for 5-10 minutes at room temperature while prepping additional accompaniments like bell peppers, onions, and warm tortillas.
  4. Cooking Technique: Heat a large skillet or griddle over medium-high heat, creating a surface that caramelizes the mushrooms and enhances their natural umami characteristics.
  5. Sautéing Method: Arrange marinated mushroom strips in a single layer on the hot cooking surface, sautéing for 3-4 minutes per side to develop a golden-brown crust and intensify the marinade’s flavor profile.
  6. Serving Presentation: Plate the sizzling mushroom fajitas immediately, garnishing with fresh cilantro, lime wedges, and complementary condiments like vegan sour cream or zesty salsa to elevate the culinary experience.

Notes

  • Marinate Mindfully: Ensure mushroom strips are evenly coated for maximum flavor absorption, using gentle folding techniques to prevent tearing delicate slices.
  • Heat Control Matters: Maintain medium-high heat to achieve perfect caramelization without burning, watching for golden-brown edges that signal optimal cooking.
  • Avoid Overcrowding: Space mushroom strips in a single layer during cooking to prevent steaming, which can make them soggy and reduce their meaty texture.
  • Customize Dietary Needs: Swap flour tortillas for gluten-free alternatives like corn tortillas or lettuce wraps to accommodate different dietary restrictions while maintaining the dish’s authentic flavor profile.
