Ingredient notes

  • Fajita seasoning: This recipe uses my favorite homemade blend. For this recipe, I’ve portioned out exactly what you need to make this recipe if you don’t already have a jar on hand.
  • Steak: The recipe calls for flank steak, but you can use rump or skirt steak, too.

Step-by-step instructions

  1. In a small bowl, whisk together chili powder, cumin, paprika, sugar, garlic powder, onion powder, cayenne pepper, and salt to taste (I like 1 teaspoon).

  1. In a large skillet over medium-high heat, heat oil until shimmering. Add steak and cook, without moving, until crispy and browned on one side, about 3 to 5 minutes. Flip and cook until browned on the second side, about 3 to 5 minutes longer. Using tongs, stand each piece on a cut side and cook, turning as necessary, until all cut sides are browned and until meat registers 120 to 125 degrees (for medium rare) or 130 to 135 degrees (for medium), 3 to 8 minutes.

Recipe FAQs

What is the best pan for fajitas?

A cast-iron pan is a great choice because it can cook at high temperatures and give you restaurant-quality fajitas. Other great options: carbon steel pans or anodized aluminum pans. Stay away from non-stick; it can’t take the heat.

How do you warm tortillas?

Heat a dry skillet over medium-high heat. Add a few tortillas in a single layer it’s okay if they’re touching a little bit) and heat until softened on one side, about 1 to 2 minutes. Flip and heat on the other side for another minute or so. Wrap in a clean kitchen towel or foil (or a hand-embroidered tortilla towel, if you have one).

What is “carryover cooking”?

When you pull meat off the stove or grill, the internal temperature will rise a few degrees because of what we call “carryover cooking.” Letting the meat rest is crucial to achieving juicy, perfectly cooked meat. If you cut the steak too soon, all the juices will flow out onto the cutting board.

  1. Delicious! Used my instant pot to sauté onions and meat. Added peppers, then 7 min, 15 min natural release. Sautéed again to thicken sauce. Delicious!5 stars

  2. This is the VERY BEST fajitas recipe. I made this the other night, cooked one half to perfect for dinner, cooked the other half a bit rare. Covered and refrigerated a few days then sautéed some onions and peppers, cut up some avocado, warmed up some roasted corn and tossed the sliced up steak in a cast iron skillet with a little olive oil and butter and a squirt or two of lime juice. Arranged it all on a bowl of cilantro lime rice and had the perfect beef bowl!5 stars
