Ingredients

1 lb Flank steak
1/3 cup Olive oil
1/4 cup Coconut aminos
1/4 cup Lemon juice
2 tbsp Worcestershire sauce
1 tbsp Garlic (minced)
1 tsp Sea salt
1/2 tsp Black pepper
2 tsp Dried oregano
1 tbsp Fresh thyme
4 tbsp Compound butter (optional, for serving)

Instructions

Step 1: Place the flank steak into a zip lock bag. Add the olive oil, coconut aminos, lemon juice, Worcestershire sauce, minced garlic, sea salt, black pepper, oregano, and thyme.
Step 2: Seal the bag and press out excess air. Massage the marinade into the steak through the bag. Refrigerate for at least 2 hours or up to 24 hours to let flavors develop.
Step 3: If desired, prepare compound butter ahead and keep it refrigerated until serving.
Step 4: Remove the steak from the fridge 30 minutes before cooking. Preheat your oven’s broiler on High and position the rack 6-8 inches from the heating element.
Step 5: Place the steak in a baking dish, discarding the leftover marinade.
Step 6: Broil the steak for 12-14 minutes, flipping halfway through, until the internal temperature reaches 130°F (57°C) for medium-rare.
Step 7: Transfer the steak to a cutting board and let it rest for 10 minutes. Slice against the grain into strips and top with compound butter if using.

Tips & Variations

For more flavor, marinate the steak overnight.
Use soy sauce instead of coconut aminos if preferred.
Try adding a pinch of red pepper flakes for a subtle heat.
If you don’t have fresh thyme, substitute with 1 teaspoon dried thyme.
Serve with grilled vegetables or a fresh salad for a complete meal.

Storage

Store leftover London Broil in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat or warm in the oven to avoid drying out the meat.

Can I use a different cut of steak?
