Roasted Portobello Tacos: A Taste of Austin’s Vegetarian Delights

This post is sponsored by Old El Paso.
While many may sing praises for Paris in the springtime, I’m here to let you in on one of life’s most delightful, albeit lesser-known, secrets: Austin, Texas, in the wintertime. Imagine escaping the chill, trading dreary skies for abundant sunshine, and swapping heavy coats for sundresses and sandals. This vibrant city, with its warm patios and lively atmosphere, offers an irresistible retreat, especially when accompanied by an endless array of delicious food. After an unforgettable February spent in the heart of Texas last year, the allure of Austin’s winter charm proved too strong to resist a return visit.
Just last month, three of my closest girlfriends and I embarked on a spontaneous long weekend getaway to Austin. Our itinerary was simple yet perfect: soak up the bright, warm sunshine on picturesque patios, enjoy the freedom of light clothing, and, most importantly, indulge in tacos, tacos, and more tacos. In fact, our culinary adventure was so focused that I’m fairly certain we managed to enjoy Mexican food for every meal, save for one. And within those meals, tacos were almost always the star attraction, often in multiples. We made sure to revisit all our favorite taco spots from our previous trip, savoring every bite of the diverse offerings this city is famous for.
The Unexpected Culinary Revelation: A Vegetarian Taco Masterpiece
My palate typically gravitates towards robust steak or delicate seafood tacos, a preference shaped by years of enjoying a wide variety of flavors. However, during this recent Austin excursion, I experienced a truly remarkable culinary shift. To my genuine surprise, the standout taco of the entire trip was a profoundly satisfying vegetarian mushroom taco from Tacodeli. This particular creation transcended expectations, presenting a harmonious blend of savory and subtly sweet notes, generously layered with fresh avocado slices. It was, quite simply, downright good, y’all – a revelation that lingered long after the last bite.
This experience sparked an immediate desire within me. I knew I had to return home and recreate this incredible dish, not just for my own enjoyment, but to share its magic with all of you. The concept of a vegetarian taco that could rival my usual favorites was too good to keep to myself. It was a testament to the power of well-crafted plant-based cuisine, proving that meatless options can be just as, if not more, hearty and delicious.
Crafting the Perfect Roasted Portobello Tacos at Home
Upon my return to Kansas, I eagerly set about adapting the recipe to my personal preferences, infusing it with a few signature twists. My primary deviation from the original was the cooking method for the portobello mushrooms. Instead of sautéing them on the stovetop, I opted to roast them in the oven. This method coaxes out an incredible depth of flavor and achieves a wonderfully soft, tender texture that melts in your mouth, though pan-searing would also yield delicious results. Roasting also allows the mushrooms to develop a slightly caramelized edge, enhancing their natural umami.
Next, I perfected my accompanying corn salsa. This vibrant component is crucial for balancing the richness of the portobello. My version is brimming with extra fresh cilantro, providing a bright, herbaceous lift, and a touch of finely diced jalapeño for a subtle, invigorating kick. The combination of sweet corn, crisp red onion, and tangy lime juice creates a medley of flavors that truly elevates the entire taco experience. This homemade salsa is incredibly versatile and can be adjusted to your preferred level of spice, making it a staple for many Tex-Mex inspired dishes.
The Essential Foundation: Quality Tortillas
No taco is complete without a stellar foundation, and for these Roasted Portobello Tacos, I turned to my trusted favorites: Old El Paso tortillas. I believe that a perfectly warmed tortilla is key to a truly authentic and satisfying taco. Gently toasting them in a pan until they become delightfully bubbly and slightly browned not only enhances their flavor but also gives them that perfect pliable texture, ready to cradle all the delicious fillings. This simple step transforms a good taco into a great one, ensuring each bite is warm and inviting.
Finally, the moment of assembly arrives. Each toasted Old El Paso tortilla is generously filled to the brim with the tender, savory roasted portobello mushrooms and a spoonful of the vibrant corn salsa. To finish, I add generous sprinkles of fresh cilantro and creamy cotija cheese. Even thousands of miles away from the bustling heart of Austin, these Tex-Mex inspired tacos hit the spot, delivering an explosion of flavor and satisfaction with every bite. The combination of textures and tastes is simply irresistible.
Why You’ll Love These Vegetarian Tacos

Furthermore, their naturally fresh ingredients make them a wholesome and healthy choice for any day of the week. And perhaps most importantly, let me tell you, they are SO incredibly delicious that they’ll quickly become a regular in your meal rotation.
The beauty of this recipe lies in its versatility and ease of preparation. It’s perfect for a quick weeknight dinner, yet impressive enough to serve at a casual gathering with friends. You can easily customize the toppings – add some pickled red onions for extra tang, a dollop of sour cream or a creamy cashew sauce for richness, or a sprinkle of your favorite hot sauce for more heat. Pairing these tacos with a refreshing margarita or a crisp Mexican lager makes for a perfect Tex-Mex themed evening.
So, a heartfelt thank you to Austin, and particularly to Tacodeli, for providing such wonderful and inspiring culinary moments. The memory of that first vegetarian mushroom taco truly sparked a creative fire in my kitchen.

- 3 large portobello caps, stems removed
- 1 Tablespoon olive oil
- salt and pepper to taste
- 1 batch corn salsa (see below)
- 1 (10-count) package Old El Paso Small Flour Tortillas
- 1 large ripe avocado, peeled, pitted and sliced
- ½ cup chopped fresh cilantro leaves
- ½ cup crumbled cotija cheese
Corn Salsa Ingredients:
- 1 ½ cups whole-kernel corn
- ⅓ cup finely-diced red onion
- ¼ cup chopped fresh cilantro leaves
- ½ teaspoon ground cumin
- ½ teaspoon salt
- 1 jalapeno, seeded and finely-diced
- juice of one lime (about 2 tablespoons)
Instructions
- How To Make The Roasted Portobello Tacos:
- Heat oven to 400°F. Line a large baking pan with parchment paper.
- Slice the portobello mushroom caps into long, thin strips. Place in a medium mixing bowl along with the olive oil, and gently toss until the mushrooms are evenly coated with the oil. Lay the mushroom strips out in an even layer on the prepared baking sheet, and sprinkle evenly with a few generous pinches of salt and pepper. Bake for 12 minutes, until the mushrooms are cooked through and soft. (If you would like them more firm, you can bake for less time.) Remove and set aside.
- Rinse out the mixing bowl, then prepare the corn salsa in it as directed below. Set aside.
- If you would like to toast your tortillas, heat a large sauté pan over medium-high heat until hot. Then place a single tortilla flat in the pan and let it cook for 10-20 seconds per side, or until the tortilla begins to brown and bubble. Immediately transfer the tortilla to a separate plate, and repeat with the remaining tortillas.
- To assemble the tacos, place 2-3 mushroom slices in the center of a tortilla, followed by 1-2 slices of avocado, a large spoonful of corn salsa, then sprinkle with fresh cilantro and cheese. Serve immediately.
- How To Make The Corn Salsa:
- Toss all ingredients together until combined. Use immediately.
