Step‑by‑Step Instructions for Portobello Vegan Fajitas
Step 1: Prepare the Fajita Sauce
In a blender, combine chipotle peppers in adobo, vegetable broth, lime juice, granulated garlic, chili powder, cumin, and fine sea salt. Blend on high until the mixture is smooth and well combined, about 30 seconds. Set this vibrant sauce aside to let the flavors meld while you sauté the vegetables.
Step 2: Sauté the Mushrooms
Heat a large skillet over medium-high heat and add a tablespoon of avocado oil. Once shimmering, add the cleaned portobello mushrooms, cooking for 4-6 minutes until browned and seared on both sides. Season them with salt and fresh cracked pepper as they cook, allowing the earthy flavors to deepen before removing them from the skillet.
Step 3: Sauté the Bell Peppers and Onions
In the same hot skillet, add another tablespoon of avocado oil if needed, then toss in the sliced bell peppers and red onion. Sauté for 6-8 minutes until the vegetables are tender and slightly charred, stirring occasionally for even cooking. This step builds a beautiful caramelization that enhances the sweetness of the fajitas.
Step 4: Combine Mushrooms and Sauce
Return the sautéed portobello mushrooms to the skillet with the bell peppers and onions. Pour in the prepared fajita sauce, stirring everything together. Cook on medium heat for an additional 1-2 minutes until everything is heated through and well-coated, allowing the flavors of your Portobello Vegan Fajitas to fully meld.
Step 5: Serve on Tortillas
Warm the corn tortillas in a small dry skillet over medium heat for about 30 seconds on each side until pliable. Fill each tortilla with a generous portion of the portobello and vegetable mixture. Add your favorite toppings such as vegan sour cream, diced cilantro, fresh lime wedges, and guacamole to personalize your delicious meal.

Make Ahead Options
These Portobello Vegan Fajitas are perfect for meal prep enthusiasts! You can prepare the fajita sauce and chop the vegetables up to 3 days in advance, allowing the sauce to meld flavors and keeping your weeknight cooking quick and easy. To maintain quality, store the sauce in an airtight container in the refrigerator and refrigerate the chopped veggies in a separate container, ensuring they stay crisp and fresh. When you’re ready to serve, simply sauté the mushrooms and vegetables as directed, add the pre-prepared sauce, and heat everything through for a satisfying meal that comes together in no time. Enjoy your flavorful, make-ahead fajitas without the last-minute rush!
