  • 1 teaspoon ground cumin
  • 1 teaspoon chili powder
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon dried oregano
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 cup chopped fresh cilantro

Method
 

Prepare the Mushrooms
  1. Start by preheating your oven to 400°F (200°C). Meanwhile, clean the portobello mushrooms by gently wiping them with a damp cloth.
  2. Remove the stems and gills using a spoon to create enough space for the stuffing.
  3. Next, place the mushrooms on a baking sheet lined with parchment paper. Drizzle each mushroom with olive oil, then sprinkle with salt and black pepper.
  4. Roast the mushrooms in the preheated oven for about 10 minutes. This initial roasting helps to soften the mushrooms and enhance their flavor.
Make the Stuffing
  1. While the mushrooms are roasting, heat a tablespoon of olive oil in a large skillet over medium heat. Add the finely chopped red onion and sauté for about 3–4 minutes until it becomes translucent.
  2. Then, add the minced garlic and diced red bell pepper to the skillet. Continue to sauté for another 3–4 minutes until the vegetables soften.
  3. After that, add the black beans, corn, and optional jalapeño to the skillet. Stir well to combine all the ingredients. Sprinkle in the ground cumin, chili powder, smoked paprika, dried oregano, salt, and black pepper. Stir again to ensure the spices are evenly distributed.
  4. Cook the mixture for an additional 5 minutes, allowing the flavors to meld together. Finally, stir in the chopped fresh cilantro and lime juice. Remove the skillet from heat and set aside.
Stuff the Mushrooms
  1. Remove the partially roasted mushrooms from the oven. Carefully spoon the prepared stuffing mixture into each mushroom cap, filling them generously.
  2. Return the stuffed mushrooms to the oven and bake for another 15–20 minutes. The mushrooms should be tender, and the stuffing should be heated through.
Add the Toppings
  1. After baking, remove the mushrooms from the oven. Sprinkle the shredded Mexican cheese blend evenly over the top of each stuffed mushroom. Follow with a sprinkle of crumbled cotija cheese.
  2. Switch your oven to the broil setting. Place the mushrooms back in the oven under the broiler for 2–3 minutes until the cheese is melted and bubbly. Keep a close eye on them to prevent burning.
Serve and Garnish
  1. Once the cheese has melted, remove the mushrooms from the oven. Allow them to cool slightly before serving.
  2. To serve, place the stuffed mushrooms on a large platter. Garnish with sliced avocado and fresh cilantro leaves. Serve with lime wedges on the side for an extra burst of citrus flavor.
