Instructions

Prepare Mushrooms: Clean the Portobello mushrooms with a damp cloth to remove dirt, then carefully remove the stems and gills to create a smooth surface for marinating and grilling.
Make Marinade and Marinate: In a bowl, whisk together olive oil, fresh lime juice, ground cumin, and chili powder. Coat each mushroom evenly with this marinade and let them sit for 15 minutes to absorb the flavors.
Preheat Grill and Cook Mushrooms: Heat your grill to medium-high. Place the marinated mushrooms on the grill and cook them for about 5 to 7 minutes on each side or until they become tender and juicy.
Warm Tortillas: During the last few minutes of grilling the mushrooms, warm the corn tortillas directly on the grill until soft and pliable.
Assemble Tacos: Slice the grilled mushrooms into strips, then place them on the warmed tortillas. Top each taco with diced avocado, chopped cilantro, a splash of lime juice, and, if desired, a dollop of sour cream or Greek yogurt for creaminess.

Notes

Removing the gills from Portobello mushrooms reduces bitterness and excess moisture, improving texture and flavor.
Marinate the mushrooms for at least 15 minutes but up to 1 hour for deeper flavor absorption.
If you don’t have a grill, the mushrooms can be cooked on a grill pan or skillet over medium-high heat.
For a vegan option, omit the sour cream or substitute with a dairy-free yogurt.
Warm tortillas gently to avoid cracking and ensure they are easy to fold.
