Simple Cooking Directions

1. Marinate beef with olive oil, lime, garlic, and spices.

4. Assemble fajitas with tortillas, beef, veggies, and toppings.

Step-by-Step Recipe Preparation

Step 1: Marinate the Beef

1. In a bowl, whisk together olive oil, lime juice, garlic, and spices.
2. Place steak in a resealable bag or shallow dish and coat with marinade.
3. Refrigerate for at least 1 hour (up to 8 hours for deeper flavor).

Step 2: Cook the Vegetables

1. Heat 1 tbsp olive oil in a cast-iron skillet over medium-high heat.
2. Add sliced peppers and onions, season with salt and pepper.
3. Cook for 6–8 minutes, stirring occasionally, until softened and slightly charred. Remove and set aside.

Step 3: Cook the Beef

1. Heat grill or skillet to high heat.
2. Remove steak from marinade, pat dry, and cook for 3–5 minutes per side (depending on thickness) until medium-rare or desired doneness.
3. Let steak rest for 5 minutes before slicing thinly against the grain.

Step 4: Assemble the Fajitas

1. Warm tortillas in a dry skillet or oven.
2. Add sliced beef and sautéed peppers and onions to each tortilla.
3. Top with guacamole, salsa, sour cream, cheese, or fresh cilantro.

How to Serve

• Serve fajitas on a sizzling hot skillet for that restaurant-style effect.
• Pair with Mexican rice, refried beans, or tortilla chips on the side.
• Add lime wedges for a fresh finishing touch.

Additional Recipe Tips

• Slice beef against the grain for maximum tenderness.
• Don’t over-marinate—the lime juice can start breaking down the beef after 8 hours.
• Use a cast-iron skillet for the best char on both veggies and beef.
• Warm tortillas before serving so they stay soft and pliable.

Variations

• Chicken Fajitas: Substitute chicken breast or thighs for beef.
• Shrimp Fajitas: Quick-cook shrimp in the same seasoning mix.
• Vegetarian Fajitas: Use portobello mushrooms, zucchini, or cauliflower instead of meat.
• Spicy Fajitas: Add jalapeños or chipotle peppers to the marinade.

Freezing and Storage

• Refrigeration: Store leftovers in an airtight container for up to 3 days.
• Freezing Beef: Freeze cooked sliced beef in freezer-safe bags for up to 2 months. Thaw overnight in the fridge.
• Freezing Veggies: Not recommended, as peppers and onions lose texture when frozen.

Special Equipment Needed

• Cast-iron skillet or grill pan
• Sharp knife (for slicing steak against the grain)
• Tongs (for flipping steak and veggies)
