Instructions

1. Marinate the beef. In a bowl or zip-top bag, combine the lime juice, 2 tablespoons olive oil, garlic, chili powder, cumin, smoked paprika, salt, and pepper . Add the sliced beef and toss to coat. Marinate in the refrigerator for at least 30 minutes, or up to 4 hours for deeper flavor .
2. Prep your grill or stovetop. When ready to cook, preheat your gas grill or charcoal grill to high heat. If using a charcoal grill, set up a two-zone fire. Place a large cast-iron skillet on the grill grates or stovetop to get screaming hot .
3. Sear the beef. Remove the steak from the marinade, letting excess drip off. Pat the steak slices lightly with paper towels . Heat 1 tablespoon of olive oil in the hot skillet. Add half of the steak slices in a single layer (do not overcrowd) and cook for 2-3 minutes per side until browned and cooked through. Remove the steak from the skillet and set aside. Repeat with the remaining steak .
4. Sauté the vegetables. Add the remaining 1 tablespoon of olive oil to the skillet. Add the sliced onions and bell peppers. Cook, stirring occasionally, for 5-7 minutes until the vegetables are tender-crisp and slightly charred . Season with salt and pepper.
5. Combine and serve. Return all the cooked steak to the skillet with the vegetables. Toss everything together for 1 minute to heat through. Serve immediately with warm tortillas and your favorite toppings .

Tips for the Perfect Fajita Skillet

• Get that smoky flavor: For an extra layer of flavor, cook your fajitas on a charcoal grill. The smoke adds a depth you can’t get from a stovetop . If using a gas grill, add a smoker box with wood chips for a similar effect.
• Use a cast-iron skillet: A cast-iron skillet is essential for achieving that restaurant-style sizzle. Make sure it is very hot before adding the steak to get a good sear .
• Don’t overcrowd the pan: When searing the steak, cook in batches if necessary. Overcrowding will cause the meat to steam instead of brown, resulting in less flavor .
• Slice against the grain: After cooking, slice the steak against the grain to ensure it is tender and easy to chew .

Delicious Variations

• Chicken Fajitas: Swap the beef for 1.5 lbs of boneless, skinless chicken breasts or thighs, sliced into strips. Cook until the chicken is cooked through and no longer pink.
• Shrimp Fajitas: Use 1.5 lbs of large shrimp, peeled and deveined. Cook for 2-3 minutes per side until pink and opaque.
• Veggie Fajitas: Omit the meat and load up with extra bell peppers, onions, and other vegetables like zucchini or mushrooms.
• Spicy Chipotle Fajitas: Add 1-2 teaspoons of chopped chipotle peppers in adobo sauce to the marinade for a smoky, spicy kick.

Storage & Reheating Instructions

To store leftovers: Let the fajita mixture cool completely, then store it in an airtight container in the refrigerator for up to 4 days . Store tortillas and toppings separately.

To reheat: The best way to reheat the beef and vegetables is in a skillet over medium heat. Add a splash of water or broth to keep the beef moist. You can also microwave individual portions, but the texture may not be as good.

Freezing: The cooked beef and vegetable mixture freezes well for up to 3 months. Thaw overnight in the refrigerator before reheating.
