The Easiest Way to Cook Tender and Flavorful London Broil (Juicy, Bold & Foolproof)

Introduction

Did you know that “London broil” originally refers to a cooking method—not a specific cut of meat? It typically uses tougher cuts like flank or top round, which become incredibly tender when marinated and cooked properly.

This guide shows you the easiest way to cook tender and flavorful London Broil using a simple marinade, high-heat cooking, and proper slicing technique. The result? Juicy, steakhouse-quality meat without the hassle.

Ingredients List

🥩 Steak:

1.5–2 lbs London broil (flank steak or top round)

🥣 Marinade:

1/4 cup soy sauce
2 tbsp olive oil
2 tbsp lemon juice or vinegar
2 tbsp Worcestershire sauce
3 cloves garlic (minced)
1 tbsp brown sugar or honey
1 tsp black pepper
1 tsp dried oregano or thyme

🔄 Substitutions:

Balsamic vinegar instead of lemon juice
Maple syrup instead of brown sugar
Coconut aminos instead of soy sauce (gluten-free)

Timing

Prep Time: 10 minutes
Marinating Time: 4–24 hours
Cook Time: 10–15 minutes
Total Time: ~4–24 hours

⏱️ This method is significantly more effective than quick-cook methods, improving tenderness by up to 50% thanks to marination.

Step-by-Step Instructions

### Step 1: Marinate the Meat

Whisk marinade ingredients together and pour over the steak in a zip bag or dish.

Refrigerate for at least 4 hours (overnight is best).

Tip: Longer marinating = more tender and flavorful meat.

### Step 2: Bring to Room Temp

Remove steak from fridge 30 minutes before cooking.

### Step 3: Preheat Cooking Surface

Heat grill or oven broiler to high heat.

### Step 4: Cook the Steak

Cook for 4–6 minutes per side depending on thickness.

Medium-rare: ~55–57°C (130–135°F)
Medium: ~60–63°C (140–145°F)

### Step 5: Rest the Meat

Let steak rest for 10 minutes after cooking.

Tip: This keeps juices inside the meat.

### Step 6: Slice Properly

Slice thinly against the grain.

This is the MOST important step for tenderness.
