Directions

  1. Season the steak

    Pat the ribeye dry. Combine chili powder, cumin, smoked paprika, 1 teaspoon salt, and black pepper, then rub the mixture over both sides of the steak.

  2. Char the vegetables

    Heat 1 tablespoon oil in a large cast-iron skillet over high. Add peppers and onion with the remaining salt. Cook for 7 to 9 minutes, stirring only occasionally, until tender-crisp and charred at the edges. Transfer to a platter.

  3. Sear the ribeye

    Add the remaining oil to the hot skillet. Cook the steak for 3 to 5 minutes per side, depending on thickness and preferred doneness. Check the center with a thermometer rather than relying only on time.

  4. Rest and slice

    Transfer the steak to a board, squeeze over half a lime, and rest for at least 5 minutes. Slice thinly across the grain, then toss the slices in the skillet juices.

  5. Build the fajitas

    Return the vegetables to the hot skillet for the table, or arrange them with the beef on a platter. Serve with warm tortillas, avocado, salsa, sour cream, cheese, and lime wedges.

Swaps & notes

Easy swaps

  • Use poblano peppers for a deeper roasted flavor and gentle heat.
  • Choose corn tortillas and confirm the spice labels to keep the meal gluten-free.
  • Swap sour cream for plain Greek yogurt or a dairy-free cultured alternative.

Cook notes

  • Ventilate the kitchen before the skillet gets hot; a true fajita sear can create smoke.
  • USDA guidance for whole beef steaks is a minimum 145°F followed by a 3-minute rest.
  • Warm tortillas in a dry skillet or wrapped in a damp towel in the microwave so they fold without cracking.

Storage

Refrigerate steak and vegetables in an airtight container for up to 4 days; keep tortillas and toppings separate. Reheat the filling in a hot skillet until it reaches 165°F.

Questions

Can I grill the ribeye instead?

Yes. Grill over high heat, turning once, and use the same thermometer and resting guidance. Cook the vegetables in a grill basket.

Can I prep anything ahead?

Slice the vegetables and mix the spice rub up to 2 days ahead. Season the steak shortly before cooking.

How can I make these less spicy for kids?

The recipe is mild, but you can reduce chili powder to 1 teaspoon and put salsa on the table instead of in the filling.
