What is London Broil?
Understanding the Cut and Cooking Method
London Broil is more of a cooking technique than a specific cut of meat. Traditionally, it involves marinating, broiling, and slicing beef against the grain to ensure tenderness.
- Common Cuts Used: Flank steak or top round steak.
- Cooking Method: High-temperature broiling or grilling.
- Why Marination Matters: Helps break down muscle fibers for a more tender bite.
Choosing the Best Ingredients
Selecting the Perfect Cut of Beef
Your choice of meat directly impacts texture and flavor. Opt for flank steak or top round with a vibrant red hue and good marbling for the best results.
Essential Ingredients for a Flavorful Marinade
A well-balanced marinade is the secret to infusing flavor and enhancing tenderness.
Key Ingredients and Their Benefits:
- Soy sauce – Boosts umami richness.
- Garlic & Onion – Adds depth and complexity.
- Olive oil – Ensures moisture retention.
- Red wine vinegar – Tenderizes the meat.
- Brown sugar – Balances acidity and aids caramelization.
- Black pepper & Salt – Elevates natural flavors.
Step-by-Step Cooking Guide
Marinating the London Broil
For the most succulent, flavor-packed steak, follow these steps:
- Prepare the marinade: Combine soy sauce, olive oil, vinegar, brown sugar, and spices in a bowl.
- Submerge the steak: Place it in a sealable bag and pour the marinade over.
- Refrigerate: Let it soak for at least 4 hours, preferably overnight.
- Bring to room temperature: Remove from the fridge 30 minutes before cooking.
Broiling the Steak to Perfection
- Preheat your broiler to high (500°F/260°C).
- Position the steak on a broiling pan about 4 inches from the heat.
- Cook for 5-7 minutes per side for medium-rare.
- Check doneness with a meat thermometer:
- Medium-rare: 130-135°F
