Portobello Asada Tacos
Portobello Asada Tacos are a flavourful vegetarian spin on carne asada tacos. The mushrooms are marinated in a orange, lime and cumin sauce and then grilled until lightly charred on the edges. This is a light and refreshing meal that is perfect for summer! These Portobello Asada Tacos are Whole30, Paleo, Vegan, Vegetarian, Dairy Free, Grain Free, Gluten Free and Specific Carbohydrate Diet Legal.
These Portobello Mushroom Asada Tacos are so tasty! If you are trying to incorporate more veggie forward meals into your life, this is a great place to start because the grilled portobello mushrooms take on a meatiness when marinated and grilled which makes them closely resemble carne asada. Portobello mushrooms are like a sponge so they absorb a lot of the marinade which means that every bit of the grilled mushroom is so flavour packed! I recommend looking for the thickest portobello mushrooms that you can find as they will have the best texture once grilled and sliced into pieces.
Why you are going to love these Portobello Asada Tacos:
- The mushrooms are so good! Portobello mushrooms are very spongy so they absorb so much flavour from the marinade even after just a few minutes of soaking. They become super tender and slightly charred on the edges once grilled so they really do resemble slices of grilled steak.
- Both vegetarians and carnivores will love these tacos! The grilled slices of portobello mushrooms taste so meaty and are surprisingly filling.
- They are incredibly easy to make and next to impossible to mess up. There is no need to worry about over or undercooking the mushrooms, once grill marks form and they are slightly charred on the edges they are done! It’s that easy.
- They are so light, fresh and flavourful! The perfect light meal for summer!
Ways to modify these Portobello Asada Tacos:
- I love using lettuce cups as the base for these tacos, but tortillas would also work. For Whole30/SCD you can use celery root tortillas and for anyone following a paleo/grain free diet Siete tortillas would work well too!
- I love making a quick salsa fresca but if you are short on time, store bought works just as well
- To make these tacos vegan, use vegan mayonnaise for the sauce
- Add more of your favourite tacos toppings including guacamole/avocado, grated cheese or shredded cabbage
- Modify the marinade by adding more orange juice, lime or spices depending on which flavours you prefer
How to cook the portobello mushrooms:
- Barbecue: This is my preferred method for cooking the mushrooms because the edges become slightly charred and they develop a slightly smoky flavour. I would recommend cooking them on high heat for 4 minutes per side.
- Grill Pan: If you don’t have a barbecue, or the weather isn’t in your favour, a grill pan is another great option. This is the grill pan that I use regularly for grilling indoors. I would recommend grilling the mushrooms on medium high heat for 5 minutes per side.
- Sandwich Press: A sandwich press is another great option for indoor grilling and you will even get those lovely grill marks.
- Oven: Roast the mushrooms on a baking tray in the oven at 400º Fahrenheit for 15 minutes, flip them over and cook for another 10 minutes.
You can marinate the portobello mushrooms up to a day in advance and leave them in the sauce overnight in the fridge. The mushrooms can also be grilled a few hours in advance and quickly reheated before serving. In terms of toppings, the sauce can be made a day or two in advance while the salsa is best made only an hour or two beforehand. Store all of the leftovers separately in the fridge and they will be good for 2 days.
