Asada Mushroom Tacos with Lime Smashed Avocado
These mushroom tacos are about to become your new obsession – imagine perfectly marinated portobello mushrooms that taste so much like traditional carne asada, you’ll do a double-take.

The secret lies in that magical marinade of orange juice, chipotle peppers, and smoky paprika that transforms humble mushrooms into something absolutely spectacular.

Every bite delivers that perfect combination of smoky, tangy, and fresh flavors that’ll have you questioning why you ever bothered with meat in the first place.

The lime-smashed avocado adds this creamy, zesty element that perfectly balances the bold mushroom flavors, while the fresh pineapple salsa brings a tropical sweetness that ties everything together beautifully.

What makes this recipe truly genius is how quickly it comes together – just 10 minutes of marinating time and 10 minutes of grilling, and you’ve got restaurant-quality tacos that cost a fraction of what you’d pay dining out.

These tacos are proof that plant-based cooking doesn’t mean sacrificing flavor or satisfaction – they’re hearty, filling, and packed with so much umami goodness that even the most dedicated carnivores will be asking for seconds.

Ingredients
For the Asada Mushrooms
- 6 portobello mushroom caps, halved
- 1 /4 cup extra virgin olive oil
- 1 /3 cup fresh orange juice
- 4 cloves garlic, minced or grated
- 1 chipotle pepper in adobo, chopped (or 2 teaspoons chili powder)
- 1 teaspoon smoked paprika
- Juice of 2 limes
- 1 /2 cup fresh cilantro, roughly chopped
- Corn or flour tortillas, warmed
For the Salted Lime Avocado
- 2 ripe avocados, mashed
- Juice and zest of 1 lime
- Maldon sea salt to taste
For the Pineapple Salsa
- 1 /2 small pineapple, cubed
- 1 jalapeño, seeded and chopped
- Juice of 1 lime
- 1 /4 cup fresh cilantro, chopped
For Serving
- Crumbled feta or cotija cheese (optional)

Instructions
Marinate the Mushrooms
- 1 Add the 6 halved portobello mushroom caps to a large ziplock bag. The key here is using a bag rather than a bowl – it ensures every surface of the mushrooms gets coated with that flavorful marinade. Next, add the 1/4 cup extra virgin olive oil, 1/3 cup orange juice, 4 minced garlic cloves, 1 chopped chipotle pepper, 1 teaspoon smoked paprika, juice of 2 limes, 1/2 cup cilantro, and a large pinch of salt. Seal the bag tightly and massage gently to distribute the marinade evenly. Let marinate for 10 minutes at room temperature, or refrigerate up to overnight for deeper flavor penetration.
Prepare the Accompaniments
- 2 While the mushrooms marinate, prepare the lime-smashed avocado by combining 2 mashed avocados with the lime juice and zest of 1 lime, plus a generous pinch of Maldon sea salt. The coarse sea salt adds a delightful textural contrast and enhances the lime’s brightness. Mash to your preferred consistency – some people love it completely smooth, while others prefer chunks for texture.
- 3 For the pineapple salsa, combine the cubed pineapple, chopped jalapeño, lime juice, fresh cilantro, and a pinch of salt in a medium bowl. The pineapple should be cut into 1/2-inch cubes for the best texture balance. If your pineapple is very sweet, add an extra squeeze of lime to balance the flavors.
Grill the Mushrooms
- 4 Preheat your grill or cast iron grill pan to high heat – you want it smoking hot for the best char. Remove the mushrooms from the marinade, letting excess drip off but don’t pat them completely dry as you want some marinade clinging to create that beautiful caramelization. Sear for 5 minutes without moving them, then flip and sear another 5 minutes until they’re lightly charred on both sides and have developed those gorgeous grill marks. The mushrooms should feel tender when pierced with a fork but still have some bite. Slice into 1/2-inch strips while still warm.
Assemble and Serve
- 5 Warm your tortillas using your preferred method – directly over a gas flame for 30 seconds per side, in a dry skillet, or wrapped in damp paper towels in the microwave for 30 seconds. Spread a generous layer of the lime-smashed avocado onto each warmed tortilla, top with the sliced grilled mushrooms, add a spoonful of pineapple salsa, and finish with crumbled cheese if using. Serve immediately while the mushrooms are still warm and the tortillas are soft.

Recommended Equipment and Kitchen Tools
Essential Tools (for best results):
- Cast iron grill pan – Creates those beautiful char marks and retains heat perfectly for achieving restaurant-quality searing on the mushrooms

Perfect Pairing Suggestions
Beverage Pairings:
A crisp Mexican lager or wheat beer complements the smoky, citrusy flavors perfectly, while the carbonation cleanses the palate between bites. For wine lovers, a Sauvignon Blanc or Albariño echoes the lime and cilantro notes beautifully. Non-alcoholic options include sparkling water with lime or a hibiscus agua fresca that won’t compete with the bold flavors.
Side Dish Recommendations:
Mexican street corn salad provides a creamy, tangy contrast that plays beautifully with the smoky mushrooms. Cilantro-lime rice offers a neutral base that soaks up the delicious taco juices. For lighter options, a jicama and cucumber salad adds refreshing crunch, while black bean and corn salad provides protein and fiber to make it a complete meal.
Complete Meal Ideas:
Start with guacamole and baked tortilla chips to keep the Mexican theme consistent. Follow the tacos with tres leches cake or lime sorbet for a refreshing finish. For casual entertaining, set up a taco bar with multiple salsas, pickled jalapeños, and Mexican crema so guests can customize their experience.
Occasion Suggestions:
These tacos shine at casual dinner parties, Meatless Monday meals, or weekend lunch gatherings. They’re perfect for Cinco de Mayo celebrations or any time you want to impress vegetarian guests without making them feel like an afterthought.

Pro Tips and Troubleshooting
Mushroom Mastery:
Don’t overcrowd your grill pan – cook mushrooms in batches if necessary to ensure proper searing. The key to great flavor is achieving those caramelized edges, which only happens with high heat and adequate space. If your mushrooms release too much liquid, increase the heat and don’t flip them until they’ve had time to develop color.
Make-Ahead Strategies:
The mushrooms actually improve in flavor when marinated overnight, making this perfect for meal prep. Prepare all components separately and store in the refrigerator for up to 3 days. The pineapple salsa gets better after sitting for a few hours as the flavors meld. Only assemble tacos just before serving to prevent soggy tortillas.
Storage and Reheating:
Leftover grilled mushrooms keep for 4 days refrigerated and reheat beautifully in a skillet over medium heat for 2-3 minutes. The avocado mixture stays fresh for 2 days with plastic wrap pressed directly onto the surface to prevent browning. Freeze extra marinade in ice cube trays for quick weeknight meals.
Scaling for Crowds:
This recipe doubles or triples easily – just use multiple ziplock bags for marinating larger quantities. When cooking for a crowd, use a large cast iron griddle or cook mushrooms in batches, keeping finished ones warm in a 200°F (95°C) oven.
