How to Make Portobello Vegan Fajitas
Step 1: Prepare the Sauce
Start by blending your chipotle peppers with vegetable broth, lime juice, granulated garlic, chili powder, cumin, and fine sea salt. This homemade fajita sauce is key—it brings a wonderful depth of flavor that elevates every bite!
Step 2: Sauté the Veggies
In a large skillet over medium-high heat, add avocado oil. Once hot, toss in your portobello mushrooms, bell peppers, and red onion. Sauté until everything is tender and slightly charred. This step is where those vibrant colors really shine!
Step 3: Combine Everything
Pour your prepared fajita sauce over the sautéed vegetables and stir well to coat everything evenly. Let it cook for another couple of minutes to ensure all those delicious flavors meld together beautifully.
Step 4: Warm Your Tortillas
While your veggie filling is cooking away, warm your corn tortillas in another pan or directly over an open flame if you’re feeling adventurous! Warming them makes them softer and easier to fold.
Step 5: Serve!
Now it’s time to dig in! Fill each tortilla with your flavorful veggie mixture. Don’t forget to top them off with vegan sour cream, chopped cilantro, lime wedges, guacamole, or whatever else makes your heart sing!

Pro Tips for Making Portobello Vegan Fajitas
Cooking is all about making it your own, and these tips will help you take your Portobello Vegan Fajitas to the next level!
- Slice the Veggies Evenly: Cutting your mushrooms, bell peppers, and onions into similar sizes ensures they cook evenly and absorb all those delicious flavors.
- Use Fresh Ingredients: Whenever possible, opt for fresh vegetables and herbs. They not only taste better but also enhance the nutritional value of your meal.
- Let the Fajita Sauce Marinate: If time allows, let your fajita sauce sit for a few minutes before adding it to the veggies. This helps meld the flavors together for a more robust taste.
- Sear at High Heat: Make sure to use a high smoke point oil and cook your veggies over medium-high heat. This creates that delicious charred flavor that makes fajitas so irresistible!
- Warm Your Tortillas: Warming the corn tortillas in a skillet or microwave makes them more pliable and enhances their flavor, ensuring that they wrap around your filling perfectly.
