If there’s any kind of dish that lends itself to vegan cooking, it’s tacos. Tortilla plus filling plus topping isn’t just reserved for the carnivores among us. There are so many options for vegetarian fillings from rice and beans to potatoes to squash–even green papaya. I’m adding yet another variation on a theme with these baby bella mushroom tacos. Bathed in savory spices and baked to perfection, these tacos are are an easy complement to any taco spread.
Here’s how it’s done:
The mushrooms
For a “meaty” mushroom taco, I chose baby portobello mushrooms, but you could chop big portobellos or even use a gourmet blend. Also, these particular mushrooms cook down significantly, so I used 16 ounces, or 1 pound, of mushrooms and fluffed it with sliced onion.
The spices
You could try many combinations, but here’s what worked for me:
- minced garlic – for earthiness
- low sodium soy sauce – to enhance the meaty flavor without adding too much salt
- olive oil – a good quality oil that will help this dish keep you satisfied
- maple syrup – a little goes a long way to balance out any astringent flavors
- ancho chili powder – gives it a more distinct flavor than a chili powder blend, which also works just fine
- allspice powder – just, like go with it, dude
- chipotle powder – for a smoky, spicy flavor
- lemon juice
- salt
After mixing the toppings with the mushrooms, use a slotted spoon to place them on the baking sheet. You might have some liquid left over in your mixing bowl. That’s okay! Just use it as a marinade for an additional taco topping. You won’t want to spoon it over the mushrooms, however, as you might end up boiling them instead of roasting them.

The process
Before poking around at recipes, I hadn’t considered how easy it would be to roast a taco topping. I expected I’d be sautéeing my way to glory here. But instead, the roasting process added flavor and a good 30 minutes of downtime to prepare a topping or, if I’m being honest, surf on Pinterest…
I roasted these fragrant little ‘shrooms at 425 degrees Fahrenheit for 30 minutes, stirring them at about 10 minutes until showtime to make sure they cooked evenly.
Toppings
I’m not gonna tell you how to top your mushroom tacos–that’s personal! But I do have a few suggestions I love.
- sliced lettuce, diced onion, and a squeeze of lime (that’s what I did!)
- this spicy avocado sauce
- pico de gallo
- chopped cilantro
- your salsa of choice
Oh! This reminds me, if you’re not making your own tortillas you might want to try warming your pre-made tortillas on a dry cast iron skillet until they just start to brown. I had a roommate who used to roast hers on an open flame, but with an electric stove, this is the next best thing! Sooo worth it.

Earthy and earth-friendly, meaty, meat-free, these roasted mushroom tacos are perfect for a vegan taco feast.
Ingredients
- 16 ounces baby bella mushrooms, sliced
- ½ onion, quartered then sliced
- 2 cloves garlic, minced
- 4 tablespoons low sodium soy sauce
- 4 tablespoons olive oil
- 1 tablespoon maple syrup
- salt to taste (I used two pinches)

- ¼ teaspoon allspice
- ½ teaspoon ground chipotle pepper
- juice of ½ lemon
- toppings of choice
Instructions
- Preheat the oven to 425 Fahrenheit.
- Place the mushrooms and onion in a medium bowl.
- In a small bowl, mix all remaining ingredients (besides the toppings) to form a dressing.
- Add the dressing to the mushrooms and mix well.
- Use a slotted spoon to transfer the mushrooms to a baking sheet. It’s okay if they bring some dressing onto the tray, but don’t pour the rest of the dressing onto the tray.
- Bake for 30 minutes. Stir the mushrooms to prevent them from sticking around 20 minutes.
- Serve on tortillas and top with any of the following: lettuce, onion, avocado, pickled onions, chopped cilantro, lime juice, or salsa of your choice.
Notes
Need to make more than six tacos? Double the dressing and, to the mushrooms and onions, add a winter squash or two sweet potatoes cut into ½-inch cubes.
