Vegetarian Portobello Tacos

Prep Time: 10 minutes
Cook Time: 10 minutes
Total Time: 20 minutes

Smoky, hearty, and super flavorful tacos made your way!


  • 1 tablespoon extra virgin olive oil
  • 1 large white or yellow onion, diced
  • 6 portobello mushrooms, diced
  • 2 red bell peppers, diced
  • 4 garlic cloves, minced
  • 1 tablespoon chili powder
  • 1 teaspoon ground cumin
  • 1/2 teaspoon spoked paprika
  • 1/2 teaspoon kosher or sea salt
  • juice from 1 lime


1. Heat the oil in a large skillet over medium heat. Add the onions and sauté, stirring frequently until soft and starting to caramelize, about 7 minutes.

2. Add the mushrooms and bell peppers, and continue to sauté, stirring frequently, until all the vegetables are soft, about 3 minutes. If your mushrooms have produced a lot of liquid, drain that out now so your skillet and vegetable mixture is fairly dry.

3. Add the garlic, chili powder, cumin, paprika, and salt. Sauté until the garlic is cooked and the spices are fragrant, about 1 minute.

4. Remove from the heat, squeeze lime juice over the mixture and toss to combine. Serve with all your favorite taco toppings.
