# How To Make It:

01 - In a medium bowl, combine 1 tablespoon olive oil, garlic, cumin, chili powder, paprika, oregano, salt, pepper, and lime juice. Add the beef strips and toss to coat. Marinate for at least 10 minutes (up to 1 hour for best flavor).
02 - Heat the remaining 1 tablespoon olive oil in a large skillet over medium-high heat. Add the marinated beef in a single layer. Sear for 2-3 minutes per side until browned but just cooked through. Remove beef from the skillet and set aside.
03 - In the same skillet, add all the sliced bell peppers and onion. Sauté for 5-7 minutes until softened and slightly charred, stirring occasionally.
04 - Return the beef to the skillet and toss to combine with the vegetables. Cook for 1-2 more minutes until everything is heated through.
05 - Serve hot with warm tortillas and your favorite toppings.

# Expert Suggestions:

01 -
  • The marinade does double duty, flavoring both the meat and creating that restaurant quality sizzle when it hits the pan.
  • Everything cooks in one skillet, which means more flavor absorption and fewer dishes to wash at the end of the night.
02 -
  • Slicing the beef against the grain is absolutely crucial, otherwise your fajitas will be chewy no matter how perfect your marinade.
  • Let your skillet get properly hot before adding ingredients, thats what gives you the restaurant quality char instead of soggy vegetables.
03 -
  • If youre cooking for a crowd, keep the skillet going at the table on a trivet, as the sizzle and aroma are half the experience of great fajitas.
  • Pat your meat dry before adding to the marinade and again before adding to the pan, this ensures proper searing rather than steaming.
