Mushrooms at a taco bar!
We serve Mushroom Asada often at taco-bar parties; it’s usually the first dish to disappear. The bold, savory marinade pairs perfectly with mushrooms, and guests always ask for seconds.
We adapted our carne asada marinade to work with mushrooms in a crock pot, and the results are excellent. The slow cooker makes this recipe especially easy: combine the ingredients, set the cooker, and in a few hours you’ll have mushrooms that smell and taste fantastic.
What kind of mushrooms should I use?
Brown mushrooms (baby portabellas or Italian mushrooms) are my preference for texture and flavor, but white button mushrooms work well too. You can also mix in wild varieties such as shiitake, oyster, or chanterelles if you like. Large packs of brown or white mushrooms are usually the most economical.
Trim and quarter the mushrooms; halve the smaller ones. If you enjoy mushrooms, consider other slow-cooker mushroom recipes for variety.
How to serve
When you add the mushrooms and marinade to the slow cooker, there will initially be more mushrooms than liquid. As they cook, mushrooms release their juices, so expect a generous amount of cooking liquid at the end. Use a slotted spoon when serving so excess liquid drains away, or spoon a little of the flavorful sauce back into each taco for extra depth.
I love a good taco!
This Crock Pot Mushroom Asada is incredibly versatile: serve it in tacos, burritos, nachos, sandwiches, or alongside rice and beans. It’s an easy, flavorful way to enjoy plant-based Mexican-style food at home.
