London Broil Fajitas: A Taste of Fiesta at Home

The sizzle of beef hitting a hot cast iron pan – it’s a sound that instantly transports me back to my college days. Late-night study sessions fueled by cheap beer and even cheaper fajitas were a weekly ritual. We’d cram into a tiny apartment kitchen, hacking away at whatever cut of beef we could afford, and the aroma alone was enough to banish any exam-induced stress. Though the ingredients have evolved (slightly!), the simple joy of assembling those flavour-packed tortillas still feels like a celebration.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 10 minutes
• Total Time: 25 minutes
• Servings: 6
• Dietary Type: Gluten-Free (if using corn tortillas)

Ingredients

• 3 lbs london broil beef
• 1 sweet onion
• 1 green pepper
• 1 cup guacamole
• 1 cup sour cream
• 2 cups colby-monterey jack cheese
• 6 large flour tortillas (or corn tortillas for a gluten-free option)

Equipment Needed

• Grill or Grill Pan
• Large skillet
• Cutting board
• Sharp knife

Instructions

1. Preheat your grill to medium-high heat. If using a grill pan, place it over medium-high heat until smoking.

2. Grill the london broil beef to medium doneness. For a 1-inch thick steak, this will take approximately 4-5 minutes per side for medium-rare, or 5-6 minutes per side for medium. Use a meat thermometer to ensure accuracy; an internal temperature of 130-135°F for medium-rare, or 135-140°F for medium. Remember that the meat will continue to cook slightly after being removed from the grill. Let the london broil rest for at least 10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful fajita.

3. While the beef is grilling, prepare the vegetables. Slice the sweet onion and green pepper into thin strips.

4. In a large skillet over medium heat, sauté the sliced onion and green pepper until they are soft and slightly caramelized. This usually takes about 5-7 minutes. Stir frequently to prevent burning. A touch of olive oil or cooking spray can help.

5. Once the london broil has rested, use a sharp knife to slice it thinly on the bias (at an angle) against the grain. This is crucial for tender fajitas! Slicing against the grain shortens the muscle fibers, making the beef easier to chew.

6. Now it’s time to assemble the fajitas! Warm the flour tortillas (or corn tortillas) according to package directions. This can be done in a dry skillet, microwave, or oven.

7. Fill each warmed tortilla with sliced london broil, sautéed onions and peppers.

8. Garnish generously with guacamole, sour cream, and shredded colby-monterey jack cheese. Serve immediately and enjoy!

Expert Tips & Tricks

• Marinate for extra flavor: For an even more intense flavor, marinate the london broil for at least 30 minutes (or up to overnight) before grilling. A simple marinade of lime juice, garlic, cumin, chili powder, and olive oil works wonders.
• Spice it up: Add a pinch of cayenne pepper or a dash of hot sauce to the sautéed onions and peppers for a spicy kick.
• Cast iron sizzle: If you have a cast iron skillet, heat it up until it’s smoking hot and then add the sliced beef. This will create a fantastic sear and add a smoky flavor. Be careful, as the oil may splatter.
• Prevent soggy tortillas: To prevent your tortillas from getting soggy, warm them just before serving and avoid overfilling them.
• Customize your toppings: Don’t be afraid to get creative with your toppings. Salsa, pico de gallo, shredded lettuce, chopped cilantro, and a squeeze of lime juice are all great additions.

Serving & Storage Suggestions

Serve these delicious London Broil Fajitas immediately while the beef is still warm and the tortillas are soft. Arrange the assembled fajitas on a platter, or serve all the ingredients separately for a customizable fajita bar.

Leftovers can be stored in the refrigerator for up to 3 days. Store the beef, vegetables, and toppings separately to prevent the tortillas from becoming soggy. Reheat the beef and vegetables in a skillet or microwave before assembling fresh fajitas. Leftover guacamole is best consumed within 24 hours, as it can brown quickly.

FAQs (Frequently Asked Questions)

Q: Can I use a different cut of beef?
A: While london broil is ideal for its tenderness and relatively quick cooking time, flank steak or skirt steak can also be used. Adjust grilling time based on the thickness of the steak.

Q: How do I prevent the beef from becoming tough?
A: The key is to slice the beef thinly against the grain after it has rested. This shortens the muscle fibers, making it easier to chew.

Q: Can I make the guacamole ahead of time?
A: Yes, you can make guacamole up to a few hours in advance. To prevent browning, press a piece of plastic wrap directly onto the surface of the guacamole and refrigerate it.

Q: How do I warm the tortillas properly?
A: You can warm tortillas in a dry skillet over medium heat, in the microwave wrapped in a damp paper towel, or in the oven wrapped in foil. Avoid overheating, as they can become dry and brittle.

Q: What other toppings can I use?
A: The possibilities are endless! Consider adding salsa, pico de gallo, shredded lettuce, chopped cilantro, diced tomatoes, or a squeeze of lime juice.
