What are the ingredients for vegan mushroom tacos?

  • Mushrooms. I used portobello mushroom caps for this recipe because I love the taste of portobello and the consistency too. However, this recipe can be made with any mushrooms you like. So use whatever mushrooms you have at home wether it’s baby bellas, crimini or shitake. I definitely recommend that you use fresh mushrooms for the best results. 
  • Tortillas. I always prefer using corn tortillas when I make tacos as traditional Mexican tacos are made with corn tortillas but you can also use flour tortillas if you prefer them or if that is what you have at home.
  • Red cabbage slaw. You can make your own cabbage slaw or use store-bought red cabbage slaw. 
  • Mashed avocado. For this recipe I used mashed fresh Hass avocado and added a bit of lime juice, salt and pepper. However, you can also use home-made or storebought guacamole to make these tacos. 
  • Spices. To give the mushrooms that “taco” flavor you can use a combination of cumin, dried Mexican oregano, powdered garlic and onion and paprika. I love spicy tacos so I also added chipotle chili powder which gives it just the right amount of heat as well as a slightly smoky flavor typical of chipotle pepper. However, if you want to take a shortcut you can replace all of the spices with store-bought taco seasoning. I’m all for shortcuts that make my life easier! 
  • Garnish. You can garnish your tacos with fresh cilantro and you can also sprinkle some queso fresco or crema for a vegetarian version of this vegan recipe.

How to roast mushrooms.

I love the taste of slow-roasted mushrooms. Portobello mushrooms are ideal for roasting but you can also roast other types of mushrooms. I usually make a large batch of roasted portobello mushrooms and then use them for other things from omeletts and fritatas to quesadillas and pasta. 

For great tasting roasted mushrooms just follow these steps.

  1. Wash your mushrooms. Always wash your mushrooms before roasting and be sure to pat them dry so you can remove as much moisture as possible.
  2. Slice larger mushrooms or quarter smaller mushrooms.
  3. Marinate for 5-10 minutes a mixture of olive oil and spices. You can get creative here with your spices. You can also include other liquids in your marinade like lime or lemon juice, balsamic vinegar or a bit of soy sauce.
  4. Slow roasting is the best way to roast. You want to give your mushrooms enough time to loose all of their moisture and start browning in the oven. Ideally your oven should be set to 375F or 400F. Depending on the type of mushrooms and the thickness of the pieces of slices it may take up to an hour to roast your mushrooms. To reduce the roasting time you can drain your the roasting pan after 15-20 to remove the liquid. 
  5. Don’t overcrowd your mushrooms. The best way to roast mushrooms is to place them in a single layer in a baking pan lined with parchment paper.
