Jump to Recipe

I’m wildly into steak fajitas because they hit hard without acting fancy. The sizzle, the char, the juicy strips of steak, the sweet snap of bell peppers, all piled high and ready for whatever mood I’m in.

I love how this recipe feels casual but still worthy of a full-on weekend spread. But honestly, I make it on random weeknights because I crave that smoky, tangy, skillet-style bite.

No fuss. Big payoff.

And the leftovers? I’m absolutely not above eating them straight from the fridge.

This is the kind of dinner I never get tired of, not even close ever.

Print Recipe (No Advertisments)

1. In a bowl whisk together 3 tablespoons lime juice, 3 tablespoons olive oil, 3 minced garlic cloves, 1 teaspoon chili powder, 1 teaspoon ground cumin, 1 teaspoon smoked paprika, 1/2 teaspoon onion powder, 1 teaspoon kosher salt and 1/2 teaspoon freshly ground black pepper.

2. Place 1 1/2 to 2 pounds flank or skirt steak in a shallow dish or resealable bag and pour the marinade over the steak; turn to coat. Marinate at room temperature 30 minutes or refrigerate up to 2 hours.

3. Thinly slice 1 large onion and 2 to 3 assorted bell peppers and set aside.

4. Heat a large cast iron skillet or heavy pan over high heat until very hot. Add a little oil if needed.

5. Remove steak from marinade and pat dry. Cook steak 3 to 5 minutes per side for medium rare to medium, adjusting time for thickness and preferred doneness.

6. Transfer steak to a cutting board and let rest 8 to 10 minutes while you finish the vegetables.

7. In the same hot skillet add a splash of oil if needed and sauté the sliced onion and peppers over medium high heat until tender and slightly charred, about 5 to 8 minutes. Season with a pinch of salt and pepper.

8. Thinly slice the rested steak against the grain into strips.

9. Warm 8 to 10 flour tortillas in a dry skillet, wrapped in foil in a low oven, or directly over a gas flame until pliable.

10. Serve steak and peppers on warm tortillas with chopped fresh cilantro, sour cream, shredded cheddar or Monterey Jack, salsa and lime wedges on the side for squeezing.

FAQ

Q: What cut of steak is best for fajitas? A: Flank or skirt steak are ideal because they are flavorful and thin enough to cook quickly. Choose a piece about 1 1/2 to 2 pounds for 4 to 6 servings.

Q: How long should I marinate the steak? A: Marinate at least 30 minutes for flavor, but 2 to 4 hours gives much better tenderness and depth. Do not exceed 12 hours to avoid an overly mushy texture from the acid.

Q: How do I cook the steak for best results? A: Sear over high heat 3 to 5 minutes per side for medium rare, depending on thickness. Let the steak rest 5 to 10 minutes before slicing to retain juices.

Q: How should I slice the steak? A: Slice thinly against the grain to shorten muscle fibers and ensure tender bites. Cut at a slight diagonal for wider strips.

Q: Can I cook the fajitas on a grill instead of a skillet? A: Yes. Preheat the grill to high and cook the steak 3 to 5 minutes per side. Grill peppers and onions in a grill basket or foil packet until tender crisp.

Q: How do I store and reheat leftovers? A: Refrigerate in an airtight container for up to 3 days. Reheat gently in a skillet over medium heat with a splash of water or broth to keep meat moist, or microwave covered in short intervals.

Steak Fajitas Recipe Substitutions and Variations

Flank or skirt steak: skirt steak, flap steak, hanger steak, or marinated thin-cut sirloin
3 tablespoons lime juice: lemon juice, orange juice, or a 1:1 mix of vinegar and water (apple cider or white)
3 tablespoons olive oil: avocado oil, grapeseed oil, or light vegetable oil
8 to 10 flour tortillas: corn tortillas, whole wheat tortillas, or warmed lettuce leaves for a low carb option

Pro Tips

1. Let the steak come close to room temperature before cooking; it shortens searing time so you get a nice crust without overcooking the interior.

2. Pat the steak very dry just before it hits the pan. Moisture is the enemy of a good sear, and a hot, dry surface gives those flavorful browned bits.

3. Slice the steak thinly against the grain while it is still slightly warm. Cutting against the grain shortens the muscle fibers, making each bite noticeably more tender.

4. Cook the peppers and onions in the same skillet you used for the steak to pick up the fond. Finish them with a splash of lime juice and a pinch of salt at the end to brighten the flavors.

5. Warm tortillas until pliable and keep them wrapped in a clean towel or foil. That soft, warm wrap makes assembling the fajitas easier and keeps everything cozy until serving.
