These portobello and poblano fajitas are a flavor-packed twist on a classic favorite. Hearty mushrooms and mild poblano peppers are sautéed with a smoky spice blend until tender and lightly charred, then blanketed with melted Mexican cheese. The result is a satisfying, meatless filling that’s perfect for stuffing into warm tortillas.
To take these fajitas over the top, we’ve included two quick homemade toppings: a fresh pico de gallo made with tomato, lime and onion and a tangy smoky red pepper crema that adds a cool, creamy finish. Together, they create a balance of smoky, spicy and fresh flavors that will make these fajitas a regular in your dinner rotation.

Ingredients
Instructions
- Wash and dry all produce. Finely dice the tomato. Halve, peel and thinly slice the onion; finely chop a few slices until you have 2 tablespoons (4 tablespoons for 4 servings). Zest and quarter the lime. Trim the stems from the portobello mushrooms and thinly slice into strips. Halve, core and slice the poblano into strips.
- In a small bowl, combine the diced tomato, chopped onion, lime zest and juice from half the lime. Season with salt and pepper. In a separate small bowl, combine the smoky red pepper crema with a squeeze of lime juice. Add water 1 teaspoon at a time until the mixture reaches a drizzling consistency. Season with salt and pepper.
- Heat a large drizzle of oil in a large pan (use a large, tall-sided pan for 4 servings) over medium heat. Add the mushrooms and poblano and season with salt and pepper. Cook, stirring, until softened and lightly browned, 6-8 minutes.
- Add a drizzle of oil, the sliced onion and half the Southwest spice (all for 4 servings) to the pan. Cook, stirring, until the vegetables are browned and very tender, 5-7 minutes more. Turn off the heat.
- Evenly sprinkle the Mexican cheese over the vegetable filling in the pan; cover the pan to melt the cheese, 1-2 minutes. Meanwhile, wrap the tortillas in damp paper towels and microwave until warm and pliable, about 30 seconds.
- Divide the tortillas among plates; fill with the cheesy vegetable filling, pico de gallo (draining first) and crema. Cut the remaining lime into wedges and serve on the side.
Recipe Tips
For extra char, cook the vegetables over medium-high heat without stirring too often.
If you prefer a spicier kick, add a pinch of cayenne or chipotle powder to the vegetable mixture.
Warm tortillas directly over a gas flame for a smoky flavor.
