Step-by-Step Instructions

1

Slice and prep the steak

Pat the flank steak dry with paper towels, then cut across the grain into thin strips. In a large bowl, whisk together lime juice, olive oil, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, and pepper. Add the steak, toss to coat, and let it marinate at room temperature for 10 to 15 minutes while you prep the vegetables.

2

Prepare the peppers and onions

Slice the bell peppers into thin strips and the onion into half moons. In a large bowl, toss the peppers and onion with olive oil, salt, and pepper until evenly coated.

3

Warm your oven and prep the sheet pan

Position a rack in the center of your oven and preheat it to 450 degrees Fahrenheit. Line a large rimmed baking sheet with foil for easy cleanup, then spread the pepper and onion mixture in an even layer.

4

Roast the peppers and onions

Place the sheet pan in the oven and roast the peppers and onions for 8 to 10 minutes, until they start to blister and soften at the edges.

5

Add the steak to the pan

Remove the hot sheet pan from the oven and spread the marinated steak strips in a single layer over the vegetables. Try not to overcrowd the pan; you want good contact with the hot surface for a flavorful sear.

6

Finish roasting and deglaze

Return the pan to the oven and roast for another 5 to 7 minutes, until the steak is cooked through and still slightly pink in the center. Remove the pan, drizzle with a little extra lime juice and a sprinkle of fresh cilantro if you like, and scrape the bottom of the pan to lift up any browned bits.

7

Warm the tortillas

While the steak and veggies finish roasting, warm the tortillas in a dry skillet over medium heat for about 30 seconds per side, or in the microwave wrapped in a damp towel for 30 to 60 seconds until soft and pliable.

8

Assemble and serve

Spoon a generous portion of the steak and pepper mixture down the center of each tortilla. Top with shredded cheese, a dollop of sour cream, a few salsa spoonfuls, and fresh cilantro. Serve immediately with lime wedges and rice if desired.

Pro Baker Tips

✓For extra tenderness, always slice the steak against the grain into thin strips.

✓Do not skip the quick roast of the peppers and onions before adding the steak; this builds deep flavor and prevents a watery pan.

✓If your oven runs hot, start checking the steak at 4 minutes into the final roast, because thin strips cook very quickly.

✓Keep the tortillas warm in a low oven until you are ready to assemble so they stay soft and flexible.

Storage & Serving Notes

◆Refrigerate leftover steak and peppers in an airtight container for up to 3 days.

◆To reheat, warm the steak in a skillet over medium heat with a splash of lime juice and a squeeze of fresh lime, then serve in warm tortillas.

◆Store tortillas separately in a sealed bag or bread box to maintain softness, and freshen them slightly in the microwave before using.

Frequently Asked Questions

Can I make this in a skillet instead of the oven?

Absolutely, you can cook the steak and vegetables in a large cast iron or stainless steel skillet over medium high heat. Sear the steak first, remove it, then cook the peppers and onions until charred in spots, and finish everything together for similar bold flavor.

What is the best cut of steak for fajitas?

Flank steak and skirt steak are ideal because they are flavorful and affordable, and they stay tender when sliced against the grain after quick cooking. Sirloin or tenderloin can work if you prefer a slightly softer texture.

How do I keep the tortillas from drying out?

Warm the tortillas just before serving and keep them covered in a clean kitchen towel or in a low oven at 200 degrees Fahrenheit so they stay soft and pliable for easy rolling.
