For an extra layer of flavor, consider adding a splash of Worcestershire sauce or a dash of smoked paprika to the steak marinade. To ensure even cooking, make sure the foil packets are well-sealed to trap the steam. If you prefer a smokier flavor, you can grill the foil packets instead of baking them in the oven. Be sure to monitor closely to prevent burning.

Follow The Directions
01
StepMarinate the Steak: In a large resealable plastic bag, combine lime juice, oil, chili powder, salt, and cayenne pepper. Add the flank steak, ensuring it's well-coated in the marinade. Remove excess air, seal, and refrigerate for 30-60 minutes. (30-60 minutes)
02
StepPreheat the Oven: Set your oven to 400 degrees F (200 degrees C). (5 minutes)
03
StepPrepare Steak Packet: Remove steak from the marinade (discard the used marinade). Place the steak in the center of a (12x18-inch) sheet of heavy-duty aluminum foil. Lift foil sides and double fold top and ends to seal, leaving space inside for heat circulation.
04
StepPrepare Vegetable Packet: Place sliced peppers, onion, and minced garlic in the center of a separate (12x18-inch) sheet of heavy-duty aluminum foil. Repeat the folding process to create a sealed packet.
05
StepWrap Tortillas: Tightly wrap the flour tortillas in another sheet of heavy-duty aluminum foil.
06
StepBake: Place both the steak and vegetable foil packets in the preheated oven. Bake until the steak reaches your desired doneness (145 degrees F (63 degrees C) for medium-rare) and the vegetables are tender, approximately 30-35 minutes. Add the wrapped tortillas to the oven during the last 10 minutes of baking to warm them through. (35-45 minutes)
07
StepOpen Packets: Carefully cut along the top fold of each packet with a sharp knife to release the steam. Thinly slice the steak against the grain.
08
StepAssemble Fajitas: Fill the warm tortillas with the sliced steak and tender vegetables. Top with your favorite accompaniments like guacamole, salsa, and sour cream. Serve immediately and enjoy!
