Baby Portobello Mushroom Tacos
I was a vegetarian when I met my husband a million years ago.
He was not.
These days we have reached a happy medium and follow more of a flexitarian diet, where I make some chicken or red meat probably two nights a week.
It was hard getting my husband to this point as he is was very much a 'vegetables are the side dish, where's the meat' kinda guy.
There was a lot of whining.
But we made it.
There's still some whining, but I am better at tuning it out now 🙂
These mushroom and smashed avocado tacos, for me, were the turning point in that journey.
There were no initial complaints (perhaps because they look like they contain thin strips of beef?) and nowadays he happily requests them time and time again.
Yay!
In fact, this is one of the few recipes in our house to find itself as a guest of honor on the menu plan every couple of months.
That's a big achievement around here, as I always have a million dishes I want to try, and rarely repeat the same dish twice.
They are that awesome 🙂
Ingredients
If you are a regular at making tacos at home you are going to know you need some tortillas, avocado, sour cream, salsa, and whatever other fillings tickle your fancy.
For these mushroom tacos we are going to make some super flavorsome mushrooms, so you will need a few extra ingredients, but don't worry, we don't need anything super fancy.
You will need:
- mushrooms: I use a mixture of baby portobellos, brown mushrooms, and white button mushrooms;
- avocado oil or other cooking oil of choice;
- tamari: this is a gluten-free low sodium soy sauce that can be found in the health section or the same section as soy sauce in most well-stocked grocery stores;
- garlic: I use fresh garlic for this recipe, but you could use dried garlic if preferred;
- smoked paprika;
- red onion;
- corn tortillas: I use mini corn tortillas, but you could use flour tortillas if preferred;
- avocado: we are going to use this to make simple guacamole, so you could always replace it with a premade guacamole if you want to speed things up in the kitchen;
- lime: fresh is best, but you could get away with using the bottled stuff if preferred;
- freshly chopped cilantro;
- Crumbled goat's cheese or queso.
Of course, you might want to add sour cream, salsa etc as well, but I will leave that to you.

How To Make
These mushroom tacos are pretty easy to make, however, there is one vital tip I cannot emphasize enough if you want the perfect textured mushrooms.
You need to get the mushrooms as thin as possible.
I cannot emphasize this enough.
TIP: If you don't get the mushrooms super thin, they aren't going to get all caramelized and crispy on the edges and you just won't get the full taste experience.
I mean they will still be delicious, but you really want that little bit of crispiness on the edge.
Trust me.
use a mandolin
This is the best way to get your mushrooms super thin.
Just work away at those mushrooms on the thinnest setting.
You will have a huge pile and it will seem like you have way too many to possibly cook, but mushrooms are full of liquid and they shrink so much when cooked.
don't have a mandolin? Use a grater.
Use the blade on the side of the grater to get super thin slices of mushroom.
Take your time, you don't want to be grating your fingers as you go.
This method will give you a slightly thicker cut than you would get from a mandolin but it will still work well for this recipe.
can i slice the mushrooms by hand?
Yes if you have to.
But you will be there all day long and it will be a bit of a pain. I wouldn't recommend it.
If you do go this route then use a super sharp knife and cut as thinly as you possibly can without cutting yourself.
Serving Suggestions
Layer the smashed avocado onto the heated corn tortilla, pile on some of the crispy mushrooms, a sprinkle of lime, some chopped red onion, a squeeze of fresh lime, and a sprinkle of goat's cheese or queso and you are good to go.
Optional extras:
- sour cream
- chili flakes
- hot sauce
- jalapenos
- thinly sliced crispy lettuce
- salsa
Or whatever other toppings you tend to add to your homemade tacos.
Handy tip for those with toddlers: my kids will NOT eat mushroom tacos...but when the mushrooms are cooked like this, combined with cheese, and served quesadilla style...let's just say they will happily devour them.
For Kids: use a couple of extra tortillas, add some cheese and make some little mushroom quesadillas (fondly referred to as bacon quesadillas...I won't tell if you don't).

Did you use smoked paprika?
Donna1 says
Yes!
Jennifer B Kinghorn says
We have made them twice now. Just keeps getting better and better.
Donna1 says
Oh I am so happy to hear that!! Thanks for taking the time to pop back and leave a comment 🙂
Anthony says
Just tried this out and struggled with my mandolin... Could you give a rough idea as to how thin they should be? Paper thin?
I was making them for myself (smaller portions) and I felt the mushrooms began to burn after 3 min in the pan. Love the flavor profiles though!
Donna1 says
Oh I am so sorry this didn't work out for you Anthony, how annoying! Yes, they should be super thin, paper thin (I normally get about 10 slices from one average sized mushroom). The mushrooms should get nice and crispy, but they shouldn't burn. Maybe your pan got too hot? Maybe try turning the temp down and just cooking them for a little longer to get them crispy enough. I hope it works out for you if you decide to try it again, I have seriously made this dish like 20 times, and it always works so well 🙂 So sorry you had troubles
Kelly says
Hi! I would love to make these, but I am wondering what the conversion of punnets to lbs. is. I've looked online and am getting mixed answers. Thanks!
Donna1 says
Hi Kelly, a punnet is roughly 1/2 lb. Thanks for the question, I should probably make it more clear on there 🙂 Hope you love them!
Molly Kumar says

Brittany at I Love Vegan says
Ugh the mashed avo + mushrooms look like such a delicious texture combo! I love everything in this recipe so I'm gonna need to try it ASAP. I usually stick to lentils, rice, or beans for my tacos/burritos, but I love the idea of a mushroom base!
Donna1 says
They are so good! Probably a little more effort than lentils or beans, but totally worth it!

Nariman says
A great recipe Donna! My husband whipped this up for me tonight for a Valentines Dinner without breaking a sweat! (this says a lot as he rarely cooks) It encompasses all the yummy ingredients I love to cook with but just done a little differently. Definitely looking forward to trying more of your recipes; I just have to convince my husband that he looks better in an apron than I do!
Whole Food Bellies says
Good luck convincing the husband....I am still trying with mine 🙂 Glad to see he made you dinner for Valentines day - that's a win!! Hope you enjoyed being pampered
