Portabella and Zucchini Tacos: A Vegetarian Fiesta

I still remember the first time I made these tacos. It was a sweltering summer evening, the kind where even the air felt heavy. I was experimenting with vegetarian options for a barbecue, determined to create something satisfying and flavorful for my non-meat-eating friends. The aroma of roasting portabellas, mingling with the sweetness of caramelized onions and zucchini, filled my kitchen. That first bite, the earthy mushrooms paired with the bright, fresh toppings, was a revelation. These tacos have been a staple ever since, a reminder that vegetarian food can be just as exciting and delicious as any meat-filled dish.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 30 minutes
• Total Time: 50 minutes
• Servings: 4
• Dietary Type: Vegetarian (easily vegan)

Ingredients

• 5 medium portabella mushrooms, stems & gills removed, sliced 1/2 inch thick
• 1/4 cup water
• 2 teaspoons dried oregano, divided
• 2 tablespoons olive oil, divided
• Coarse salt & fresh ground pepper, to taste
• 4 medium zucchini, cut into 2 inch by 1/2 inch sticks
• 1 medium red onion, halved & sliced 1/2 inch thick
• 12 corn tortillas (4-inch size)
• 6 ounces Monterey Jack cheese, shredded (optional – omit for vegan)
• Fresh guacamole (optional)
• Fresh salsa
• Shredded lettuce

Equipment Needed

• 2 Large rimmed baking sheets
• Small skillet
• Clean kitchen towel

Instructions

1. Preheat your oven to 425°F (220°C). Make sure your oven rack is positioned in the center for even cooking.

2. Prepare the mushrooms: On a large rimmed baking sheet, combine the sliced portabella mushrooms, water, 1 teaspoon of dried oregano, 1 tablespoon of olive oil, and season generously with coarse salt and fresh ground pepper. Toss everything together to ensure the mushrooms are evenly coated. The water helps to create steam during roasting, which aids in softening the mushrooms.

3. Prepare the zucchini and onions: On another rimmed baking sheet, toss the zucchini sticks and sliced red onion with the remaining 1 teaspoon of dried oregano and 1 tablespoon of olive oil. Season generously with coarse salt and fresh ground pepper. Make sure the zucchini and onions are spread out in a single layer to promote even browning.

4. Roast the vegetables: Place both baking sheets in the preheated oven. Roast the vegetables, tossing occasionally, until they are browned and fork-tender, approximately 25-30 minutes. Keep a close eye on them because the zucchini and onions will likely be done sooner than the mushrooms. You want them to be slightly caramelized and tender, but not mushy. If the zucchini and onions are browning too quickly, you can remove them from the oven and set them aside while the mushrooms continue to roast.

5. Warm the tortillas: When the roasting is almost finished, heat a small skillet over medium-high heat. Warm the corn tortillas briefly on each side, about 15-20 seconds per side. This goes very quickly, so be vigilant. You want the tortillas to be a bit browned and pliable, but still nice and soft. If the tortillas become too stiff, they will crack when you fold them. As you warm them, wrap the warm tortillas in a clean kitchen towel to keep them soft and prevent them from drying out.

6. Assemble the tacos: To serve, pile the roasted portabella mushrooms, zucchini, and red onions onto the warm corn tortillas. Top with your desired toppings, such as shredded Monterey Jack cheese (if using), fresh guacamole, fresh salsa, and shredded lettuce.

7. Serve immediately and enjoy!

Expert Tips & Tricks

• Mushroom Prep: Ensure you remove the gills from the portabella mushrooms. They can make the tacos a bit muddy in flavor. Use a spoon to gently scrape them out.
• Even Roasting: For the most even roasting, ensure the vegetables are cut into uniform sizes. This helps them cook at the same rate.
• Tortilla Warmth: A dry skillet or comal works best for warming tortillas. Avoid using oil, as it can make them soggy. Alternatively, you can quickly char them over an open gas flame for a smoky flavor, but watch carefully to prevent burning.
• Flavor Boost: A squeeze of fresh lime juice over the roasted vegetables right before serving brightens the flavors and adds a zesty touch.
• Spice it Up: Add a pinch of red pepper flakes to the vegetables while roasting for a little heat.

Serving & Storage Suggestions

Serve these Portabella and Zucchini Tacos immediately for the best flavor and texture. Arrange the tacos attractively on a platter, alongside bowls of salsa, guacamole, and any other desired toppings.

Leftover roasted vegetables can be stored in an airtight container in the refrigerator for up to 3 days. Reheat them in a skillet over medium heat or in a microwave until warmed through. Leftover warmed tortillas can become stale quickly, so it’s best to store them separately in a sealed bag or container. Reheat the tortillas wrapped in a damp paper towel in the microwave or in a dry skillet.

These tacos are best enjoyed fresh and are not suitable for freezing once assembled.
