  • 1 pound flank steak, thinly sliced
  • 2 limes, juiced
  • 2 tablespoons olive oil
  • 3 cloves garlic, minced
  • 1/2 teaspoon cumin
  • 1 teaspoon chili powder
  • 1 teaspoon salt


  • 2 to 3 bell peppers, all different colors, sliced
  • 1 medium yellow onion, sliced
  • 2 teaspoons olive oil
  • 1/2 teaspoon dried oregano
  • 1/4 teaspoon garlic powder, or to taste
  • 1/4 teaspoon sweet or smoked paprika, or to taste
  • salt and fresh ground pepper, to taste


  • flour tortillas
  • avocado slices
  • lime wedges
  • sour cream
  • cilantro


  • Preheat oven to 425F.
  • Place the steak slices in a large mixing bowl, a baking dish, or a freezer bag.
  • Whisk together the lime juice, olive oil, garlic, cumin, chili powder, and salt.
  • Pour the marinade over the steak slices, mix around until evenly coated, and cover. Refrigerate for 15 minutes, or up to 24 hours.
  • Remove steak from fridge and set aside to come to room temperature.
  • Cut up four 12 x 12 aluminum foil sheets and set aside.
  • Place bell pepper slices and onion slices in a large mixing bowl and season with olive oil, oregano, garlic powder, paprika, salt and pepper; mix to combine.
  • Portion out the peppers mixture and arrange in the center of each foil sheet.
  • Remove steak from marinade; portion out the steak slices and arrange over the vegetables inside the foil packs. Discard marinade. 
  • Close the foils and wrap them up tightly around the steak and vegetables.
  • Arrange foil packs on a baking sheet and cook for 15 minutes, or until done. I suggest to cook for 13 minutes in the oven, then open up the packets and put under the broiler for a couple minutes so to get that bit of browning on top.
  • You can also grill the steak fajitas foil packets over high heat for around 7 minutes per side. An instant read thermometer should read 120F in center for medium rare, and 130F for medium.
  • Remove from oven or grill.
  • Serve immediately over flour tortillas, with avocado slices, lime wedges, sour cream, and cilantro.
  • If you’re on a low carb diet, serve the steak fajitas over a salad, or make lettuce wraps. You can also eat this as is, straight from the foil packet.
