Ingredients

  • 1 lb beef flank steak
  • 1/4 cup lemon juice
  • 2 large cloves garlic, minced

  • 1/2 teaspoon sugar
  • 1/2 teaspoon dried thyme leaves
  • 1/2 teaspoon salt
  • 1 large onion
  • 1 bell pepper

  3. Marinate the sliced steak in the mixture for at least 4 hours.
  4. Slice the large onion and bell pepper into strips.
  5. Heat a skillet over medium-high heat.

  7. Add the sliced onions and peppers to the skillet and cook until tender.

Tips & Substitutions

For a more tender beef, consider marinating overnight to deepen the flavor. If flank steak is unavailable, skirt steak or sirloin can be good substitutes. Adding a dash of chili powder or cumin to the marinade can enhance the dish's flavor profile. To save time, pre-sliced bell peppers or pre-made fajita seasoning can be used.

Serving Suggestions

Serve the fajitas hot with warm tortillas, and consider adding toppings like guacamole, sour cream, or salsa for extra flavor. These fajitas also pair beautifully with Rice Sabrosa or a fresh salad for a balanced meal. For a fun twist, try serving them alongside nachos or as part of a platter with other Mexican recipes.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm in a skillet over medium heat until heated through, or use a microwave for quick reheating. If reheating in the microwave, cover to prevent drying out.

Frequently Asked Questions

Can I use chicken instead of beef for fajitas?

Absolutely! Chicken breast or thighs can be substituted in place of beef. Just adjust the cooking time, as chicken may take less time to cook through. Marinating chicken in the same mixture will provide a delicious flavor similar to beef fajitas.

What can I do if I don't have Worcestershire sauce?

If you don’t have Worcestershire sauce, a combination of soy sauce and a bit of vinegar can work as a substitute. You can also use balsamic vinegar or apple cider vinegar with a pinch of sugar to mimic the sweet and tangy profile.

How can I make this recipe vegetarian?

To make the fajitas vegetarian, replace the beef with a mix of grilled vegetables like zucchini, mushrooms, and portobello mushrooms. Tofu or tempeh can also be marinated and used for added protein and texture, keeping the marinade to enhance the flavors.
