Steak Fajitas Recipe

I guarantee these steak fajitas deliver tender beef, vivid peppers, and a stack of tortillas that disappear faster than you can say fiesta.

And I adore these steak fajitas because they are loud, juicy, and totally unapologetic. I crave the sear on a good flank or skirt steak that gives each bite a smoky, meaty edge.

I want bell peppers blistered until they go sweet and slightly charred, adding crunch and color. I like the mess and the rush of bright, salty bites that follow.

I eat them with my hands, the juices running and the flavors colliding. No fuss, just bold, savory satisfaction that makes weeknights feel worth it.

I keep dreaming about the leftovers the next day, irresistible. Honestly, I can’t.

• 3 tablespoons olive oil, divided
• 2 tablespoons fresh lime juice
• 2 tablespoons soy sauce or Worcestershire sauce
• 3 cloves garlic, minced
• 1 teaspoon ground cumin
• 1 teaspoon chili powder
• 1/2 teaspoon smoked paprika
• 1/2 teaspoon kosher salt, plus more to taste
• 1/4 teaspoon freshly ground black pepper
• 1 teaspoon brown sugar or honey (optional)
• 1 large yellow or white onion, sliced
• 2 bell peppers, mixed colors, sliced

How to Make this

1. Trim any excess fat from 1 1/2 pounds flank or skirt steak and place in a shallow dish or zip bag; whisk together 2 tablespoons olive oil, 2 tablespoons fresh lime juice, 2 tablespoons soy sauce or Worcestershire sauce, 3 cloves minced garlic, 1 teaspoon ground cumin, 1 teaspoon chili powder, 1/2 teaspoon smoked paprika, 1/2 teaspoon kosher salt, 1/4 teaspoon black pepper and 1 teaspoon brown sugar or honey if using, then pour over the steak and refrigerate at least 30 minutes and up to 4 hours.

2. When ready to cook, take steak out 15 minutes before cooking to come toward room temp; heat a large heavy skillet or grill pan over high heat and brush with about 1 tablespoon olive oil.

3. Remove steak from marinade and shake off excess, then sear the steak 3 to 5 minutes per side for medium rare to medium depending on thickness, do not crowd the pan; use tongs and only flip once for the best crust.

4. Transfer steak to a cutting board, tent loosely with foil and let rest 5 to 10 minutes so juices redistribute while you cook the veggies.

5. In the same skillet add the remaining 2 tablespoons olive oil if needed, toss in 1 large sliced onion and 2 sliced bell peppers, season with a little salt and the remaining pinch of pepper and cook over medium high heat until browned and softened about 6 to 8 minutes, stirring often.

6. Slice the rested steak thinly across the grain against the muscle fibers for tenderness, then toss the sliced steak back into the skillet with the peppers and onions to warm through for a minute or two, taste and adjust salt, pepper or lime as needed.

7. Warm 8 to 10 flour or corn tortillas in a dry skillet or wrapped in foil in a 350 F oven for a few minutes until pliable, or microwave wrapped in a damp towel for 20 to 30 seconds.

8. Build fajitas by piling steak and peppers onto warm tortillas, sprinkle with 1/2 cup chopped fresh cilantro if using, and add 1 cup shredded cheddar or Monterey Jack cheese if you like it melty.

9. Serve immediately with sour cream, salsa, and guacamole for topping and 2 lime wedges for squeezing over the top, and don’t forget extra hot sauce if you want heat.

FAQ

Steak Fajitas Recipe Substitutions and Variations

• Flank or skirt steak: try sirloin tip, hanger, or flat iron for similar beefy flavor and texture; for a lighter option use sliced chicken breast or thigh instead, they cook faster and still soak up the marinade.
• Soy sauce or Worcestershire sauce: swap with tamari for gluten free, or coconut aminos for a milder, slightly sweeter taste; balsamic vinegar mixed with a pinch of salt works in a pinch.
• Flour or corn tortillas: use warmed butter lettuce leaves for low carb fajitas, or pita pockets and soft flatbreads if you dont have tortillas; stacked corn tortillas work better than cold ones, brush with oil and warm them on the pan.
• Cheddar or Monterey Jack cheese: crumble queso fresco or cotija for a more authentic Mexican vibe, or grate pepper jack for some heat; omit cheese entirely and add extra salsa and avocado if you want it dairy free.

Pro Tips

1. Marinate longer if you can, even overnight. The acid and soy help tenderize the meat and punch up flavor, so don’t be shy. Just keep it covered and refrigerated so it stays safe.

2. Let the steak come room temp for about 15 minutes before searing. If it’s too cold it steams and won’t get that nice crust, and flipping only once really helps form the crust and keeps juices inside.

3. Slice against the grain and slice thin. Cutting across the muscle fibers is what makes flank or skirt steak feel tender, otherwise it’ll be tough no matter how good the marinade is.

4. Use high heat for the meat, then medium high for the veggies. Cook steak fast to avoid overcooking, rest it while you do the peppers and onions, then toss them together for a minute to marry the flavors. Add a squeeze of lime at the end, it brightens everything up.
