🛒 Ingredients You’ll Need (Expanded)
For the Marinade:
- ¼ cup olive oil – A neutral, rich base that helps distribute spices and keeps the steak juicy.
- ¼ cup fresh lime juice – Adds zesty brightness and helps tenderize the beef.
- 2 tablespoons low-sodium soy sauce – Adds deep umami and saltiness without overpowering.
- 1 tablespoon Worcestershire sauce – Boosts savory, meaty flavor.
- 1 teaspoon ground cumin – Brings earthy warmth, a classic Tex-Mex spice.
- 4 cloves garlic, minced – Fresh, bold, and aromatic.
- 1 jalapeño, finely chopped (ribs/seeds removed) – Mild heat; add more or less to taste.
- ½ teaspoon salt – Essential for seasoning the meat properly.
- ½ teaspoon black pepper – Balances the marinade’s acidity.
- ⅛ teaspoon crushed red pepper flakes – Optional, for a spicy kick 🔥
For the Fajitas:
- 1.25 lbs flank or skirt steak – Flank has a great texture; skirt is more tender and soaks up marinade beautifully. Trim off any excess fat before marinating.
- 2 tablespoons olive oil – Divided for cooking meat and veggies.
- 3 bell peppers (red, yellow, green) – Thinly sliced for color, crunch, and sweetness.
- 1 white or yellow onion – Sliced thin; caramelizes beautifully for a rich base.
- 12 small flour or corn tortillas – Warmed before serving. Choose your favorite — flour is classic, corn adds more texture.
- Optional toppings: sour cream, guacamole or sliced avocado, pico de gallo, salsa, fresh cilantro, shredded cheese, lime wedges 🍋
👨🍳 How to Make Steak Fajitas
Step 1: Make the Marinade
Whisk together all marinade ingredients in a large bowl or zip-top bag. Add the steak, ensuring it’s fully coated. Refrigerate for at least 1 hour, but ideally 4–12 hours for deeper flavor.
Step 2: Bring to Room Temperature
Remove steak from the fridge and let it sit at room temperature for 30 minutes before cooking — this helps it cook evenly.
Step 3: Cook the Steak
Heat 1 tablespoon olive oil in a cast iron skillet (or preheat your grill). Remove steak from marinade, letting excess drip off. Cook over medium-high heat for 4–8 minutes per side, depending on thickness and desired doneness. For medium, aim for 145°F, or 150°F for medium-well.
Step 4: Rest the Meat
Transfer cooked steak to a cutting board, cover loosely with foil, and let it rest for 5–10 minutes to lock in juices.
Step 5: Sauté the Veggies
In the same skillet (or grill pan), add another 1 tablespoon olive oil. Sauté bell peppers and onions over medium-high heat for 7–10 minutes, stirring occasionally, until soft and lightly charred.
Step 6: Slice the Steak
Slice thinly against the grain — this ensures tenderness in every bite.
Step 7: Warm the Tortillas
Heat tortillas in a dry skillet or wrap in a damp paper towel and microwave for 20–30 seconds.
Step 8: Assemble & Serve
Layer sliced steak and veggies into tortillas, add toppings of your choice, and enjoy hot!

❓ FAQs About Steak Fajitas
Q: Can I use chicken instead of steak?
A: Absolutely! Chicken thighs or breasts work great — just adjust cooking time.
Q: What’s the best cut of steak for fajitas?
A: Flank or skirt steak are both excellent — just slice thinly across the grain after cooking.
Q: Can I grill the veggies too?
A: Yes! Use a grill basket or cast iron pan directly on the grill grates.
Q: Are flour or corn tortillas better?
A: It’s personal preference! Flour is softer and pliable; corn gives a more authentic texture.

Instructions
- Combine all marinade ingredients in a zip-top bag or shallow dish. Seal the bag or whisk in the dish to mix thoroughly.

- Let the steak sit at room temperature for 30 minutes before cooking.
- Heat 1 tablespoon olive oil in a cast iron skillet or grill pan over medium-high heat. Once hot, place the steak in the pan, discarding excess marinade. Cook for 4-8 minutes per side, depending on thickness and desired doneness. Lower the heat to medium if the edges begin to burn. Aim for 145°F for medium or 150°F for medium-well.

- Transfer the cooked steak to a cutting board or clean plate and let it rest for 5-10 minutes before slicing.
- In the same skillet, heat another tablespoon of olive oil. Add the sliced peppers and onions and cook for 7-10 minutes, stirring occasionally, until softened and lightly charred in spots.

Notes
Store leftover steak and fajita vegetables in an airtight container in the refrigerator for up to 3 days. For best results, reheat in a skillet on the stove or gently in the microwave-use caution with the microwave to avoid overcooking, which can make the steak tough. You can also reheat in a 350°F oven; cover the dish with foil to retain moisture and keep the steak from drying out.
