Sheet Pan Fajitas | Flank Steak Marinade Recipe · Certified Angus Beef ®
Certified Angus Beef shows tossing sliced flank steak, bell peppers, and onions with fajita rub on a sheet pan and roasting under high heat.
- Target //Cook at Broil High (500°F+ / 260°C+) for 10 min cook + 5 min rest.
- Doneness //Pull when internal temperature reaches 145°F (USDA safe minimum). Rest 5 mins before slicing.
- Golden Rule //The preheated sheet pan is the whole trick — this is how restaurants get the fajita platter to arrive sizzling. Home ovens can hit 550°F under the broiler if you preheat properly, matching a commercial griddle.
- Family Tweak //Set aside a portion of the peppers and steak before broiling and toss with only 1 tsp of the spice mix. Broil separately for 6 minutes for milder, unsauced fajitas. Serve with cheese on the tortilla.

Step by step
Tap a step to cross it offPreheat the Sheet Pan Under the Broiler
8 minPosition an oven rack 6 inches below the broiler element. Place a half sheet pan (or cast-iron sheet) on the rack. Turn broiler to HIGH. Preheat for 8 minutes while you prep.
WhyThe preheated hot pan mimics a griddle — it sears the bottom of the meat and peppers on contact, giving you that fajita-platter char in the oven.
Slice Steak and Vegetables
Cut 1.5 lbs skirt steak across the grain into 1/4-inch strips (if the strips are longer than 4 inches, cut in half). Slice 3 bell peppers (mixed colors) into 1/4-inch strips. Slice 1 red onion into 1/4-inch half-moons.
WhySkirt steak has very visible grain — cut ACROSS the fibers, not along them. Fajitas made along the grain eat like rubber bands.
Mix Spice and Toss Everything
In a small bowl, mix 1 tbsp chili powder, 2 tsp ground cumin, 1 tsp smoked paprika, 1 tsp garlic powder, 1 tsp onion powder, 1 tsp kosher salt, 1/2 tsp black pepper, and 1/4 tsp cayenne. In a large bowl, toss steak, peppers, and onion with 2 tbsp olive oil, 2 tbsp lime juice, and the spice mix.
WhyThis spice ratio is Tex-Mex fajita standard — steal it for chicken, shrimp, or pork fajitas too. One recipe, three dinners.
Load the Hot Pan Fast
Pull the hot pan from the oven — it will be scorching. Spread the steak-and-pepper mixture across the pan in a single layer. It should sizzle loudly on contact.
WhyEvery second the pan is out of the oven, it loses heat. Load fast and get it back under the broiler within 45 seconds — that sizzle is the whole recipe.
Broil 8 Minutes Without Opening
10 minSlide the pan under the broiler. Broil 8 minutes without opening the door — the heat drops 100°F every time you peek. Then open, stir once, and broil 2 more minutes for extra char.
WhyPeeking is the enemy of char. Set a timer, trust the smoke coming from under the door — that's flavor, not disaster.
Rest and Serve
5 minPull the pan out and let rest 5 minutes on the stovetop — juices redistribute and the peppers stop cooking. Serve family-style with warm flour tortillas, lime wedges, sour cream, guacamole, and cotija.
WhyWarming tortillas straight over a gas burner for 15 seconds a side is the traditional way — the char adds smoke that pairs with fajita meat. Skip the microwave, which steams them limp.
- Dad pro tip
- The preheated sheet pan is the whole trick — this is how restaurants get the fajita platter to arrive sizzling. Home ovens can hit 550°F under the broiler if you preheat properly, matching a commercial griddle.
- Kid & toddler adjustment
- Set aside a portion of the peppers and steak before broiling and toss with only 1 tsp of the spice mix. Broil separately for 6 minutes for milder, unsauced fajitas. Serve with cheese on the tortilla.
- Serve with
- Warm flour or corn tortillas · Cilantro-lime rice and refried beans · Guacamole, sour cream, and pico de gallo
- Reheating
- Reheat in a hot skillet over medium-high for 3 minutes — never microwave, which steams the char off. Wrap fresh in a tortilla with cheese and pan-crisp for the best leftover fajita quesadilla.

Frequently Asked Questions
Can I use flank steak instead of skirt?
Yes — flank is nearly the same cut in terms of preparation. Slice against the grain, same broil time. Skirt has slightly better fajita texture.
Can I do these with chicken instead?
Yes, 1.5 lbs boneless thighs sliced into strips. Same spice, same method — but drop broil time to 8 minutes total. Chicken burns faster than beef.
How do you reheat leftover sheet pan steak fajitas without ruining the texture?
Reheat in a hot skillet over medium-high for 3 minutes — never microwave, which steams the char off. Wrap fresh in a tortilla with cheese and pan-crisp for the best leftover fajita quesadilla.
What is the target internal temperature for this recipe?
Confirm internal core temperature reaches 145°F using an instant-read digital probe thermometer inserted into the thickest part. Allow the meat to rest for 5 minutes before slicing to let carryover heat equalize and lock in juices.
How do I adapt this meal for picky kids or toddlers?
Set aside a portion of the peppers and steak before broiling and toss with only 1 tsp of the spice mix. Broil separately for 6 minutes for milder, unsauced fajitas. Serve with cheese on the tortilla.
What are the best side dishes to serve with this?
Recommended sides include Warm flour or corn tortillas, Cilantro-lime rice and refried beans, Guacamole, sour cream, and pico de gallo.
