8 fajitas


  • 2 tablespoons extra-virgin olive oil

  • 1 teaspoon chili powder

  • 1 teaspoon garlic powder

  • ½ teaspoon ground cumin

  • ¼ teaspoon salt

  • 1 pound flank steak, trimmed

  • 4 cups sliced onions

  • 2 cups sliced bell peppers

  • 2 cups sliced poblano peppers

  • 8 (6 inch) corn tortillas, warmed

  • ½ cup guacamole

  • Lime wedges for serving

  • Cilantro for garnish


  1. Position racks in upper and lower thirds of oven and place a large rimmed baking sheet on each; preheat to 500 degrees F.

  2. Combine oil, chili powder, garlic powder, cumin and salt in a large bowl. Rub steak with half of the spice mixture. Add onions, bell peppers and poblanos to the bowl and toss to coat. Carefully place the steak on the pan on the top rack. Carefully spread the vegetables on the pan on the lower rack. Roast until the steak and vegetables are starting to brown, about 8 minutes.

  3. Flip the steak and stir the vegetables. Turn the broiler to high and continue cooking the steak to desired doneness (an instant-read thermometer inserted in the thickest part will register 120 degrees F for medium rare) and the vegetables until charred, about 6 minutes more. Transfer the steak to a cutting board and let rest for 5 minutes.

  4. Slice the steak across the grain and serve in tortillas with the vegetables and guacamole. Serve with lime wedges and cilantro, if desired.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
