A sheet pan makes this version of a Tex-Mex staple simple enough to pull off on any given weeknight.

The spicy avocado crema takes it over the top, but if you're short on time, substitute fresh avocado slices and dollops of your favorite sour cream.

Tested size: 3-6 servings

  • For the fajitas
  • 2 tablespoons fresh lime juice
  • 2 tablespoons extra-virgin olive oil
  • 1 tablespoon chili powder (may substitute 1 teaspoon each ground ancho chile, ground cumin and Spanish smoked paprika)
  • 1 teaspoon kosher salt, or more as needed
  • 1 small sweet potato (8 ounces), scrubbed well and then cut lengthwise into 1/2-inch-wide strips
  • 4 poblano chile peppers (1 pound), stemmed, seeded and cut lengthwise into 1/2-inch-wide strips
  • 1 yellow onion, thinly sliced
  • 2 portobello mushroom caps (6 to 8 ounces), cut into 1/2-inch-wide strips
  • Six 8-inch-wide flour tortillas
  • 1/2 cup packed cilantro, chopped
  • Lime wedges, for serving
  • For the crema
  • Flesh of 1 ripe avocado
  • 1/4 cup canned coconut milk (full-fat or low-fat)
  • 2 tablespoons fresh lime juice
  • 1/2 serrano chile pepper, seeds and ribs removed
  • 1/4 cup packed cilantro
  • 1/4 teaspoon kosher salt, or more as needed


For the fajitas: Place a large rimmed baking sheet on the middle rack in the oven; preheat to 450 degrees.

Whisk together the lime juice, oil, chili powder and salt in mixing bowl. Add the sweet potato, poblanos, onion and mushrooms, tossing until evenly coated.

Carefully remove the baking sheet from the oven. Working quickly so the pan stays hot, arrange the vegetables on it in an even layer. Roast until the sweet potato is tender and the other vegetables are deeply browned on the edges, 15 to 20 minutes. Taste, and add more salt, as needed.

During the last few minutes of roasting, wrap the stack of flour tortillas in aluminum foil and place in the oven (on a lower or upper rack) to warm them.

While the vegetables are roasting, make the crema: Combine the avocado, coconut milk, lime juice, serrano, cilantro and salt in a food processor and puree until smooth.

Fill the warmed tortillas with the roasted vegetable mixture. Add dollops of the crema and some cilantro to each portion. Serve with the lime wedges.
