“ANT” Kelly’s London Broil Marinade Recipe: A Step-by-Step Guide
London broil is a favorite cut for grilling enthusiasts and home cooks alike, celebrated for its robust flavor and versatility. The secret, however, to unlocking its true potential lies in the marinade. “ANT” Kelly’s London Broil Marinade stands out for its ability to impart rich flavor, tenderize the meat, and provide a memorable dining experience. This guide takes you through every step and detail, ensuring you achieve steak perfection.
What Is London Broil?
London broil traditionally refers to a cooking method rather than a specific cut of meat. While it usually involves flank steak or top round, the hallmark technique is marinating the steak, then broiling or grilling before slicing thinly across the grain.
- Flank steak: Lean, flavorful, benefits greatly from marinating.
- Top round steak: Slightly thicker, excellent for soaking up marinade flavors.
- Alternative cuts: Some opt for skirt steak or other lean roasts.
The success of London broil largely depends on a well-crafted marinade that both flavors and tenderizes the meat.

Marinade Ingredients Breakdown
The ingredients in this marinade work in harmony to produce depth of flavor and optimal tenderness. Precise measurements and substitution options are noted for customization.
| Ingredient | Role in Marinade | Notes & Substitutions |
|---|---|---|
| Soy Sauce | Salty base, adds umami | Can use tamari for gluten-free |
| Vegetable Oil | Moisture, helps carry flavors | Swap with olive or avocado oil |
| Lemon Juice | Acidity, tenderizes meat | Fresh is best; bottled acceptable |

| Garlic | Pungency, aromatic richness | Fresh minced preferred |
| Dried Oregano | Herbal notes, balances flavors | Fresh oregano can substitute |
| Black Pepper | Mild spice, enhances aroma | Fresh cracked pepper for best result |
| Optional Sugar/Honey | Balances acidity and salt | Adjust to taste |
Preparing the Marinade: Step-by-Step Instructions
Follow these steps for ideal flavor absorption and meat tenderness:
- Mix all marinade ingredients thoroughly in a bowl. Whisk until fully combined.
- Lightly score the meat on both sides in a crosshatch (diamond) pattern. This technique lets more marinade permeate the steak and tenderizes it further.
- Place the steak in a large resealable bag or non-reactive dish.
- Pour marinade over the steak, covering all surfaces. Seal the bag, removing excess air, or cover the dish.
- Marinate in the refrigerator for 4–24 hours. The longer, the richer the flavor—but don’t exceed 24 hours for best texture.
Tip: If making ahead, overnight marinating yields maximum juiciness.
Grilling and Cooking London Broil
Once marinated, cooking London broil is straightforward—but a few best practices ensure success.
- Bring steak to room temperature before cooking: Letting it rest outside the fridge for 30–60 minutes ensures even cooking.
- Preheat your grill or broiler: High heat helps create a flavorful crust without overcooking.
- Pat steak dry: Blotting excess marinade prevents flare-ups and promotes better browning.
- Grill or broil 4–6 minutes per side: Exact time varies by thickness and desired doneness. Use a meat thermometer for accuracy (125–130°F for medium-rare).
- Rest the meat for 5–10 minutes after cooking; this allows juices to redistribute for a moist, tender texture.
- Slice thinly against the grain: Key for tenderness; identify the direction of muscle fibers and cut perpendicular to them.
Serving Suggestions and Pairings
London broil’s rich flavor pairs well with a variety of sides, sauces, and garnishes. Consider these serving ideas:
- Classic sides: Roasted potatoes, grilled asparagus, corn on the cob, or simple green salads.
- Sauces: Chimichurri, horseradish cream, or a drizzle of the reserved marinade (boiled).
- Leftovers: Thinly sliced for sandwiches, wraps, or next-day steak salads.
Tips for Perfect London Broil Marinade
Expert advice for elevating your steak:
- Scoring method matters: Crosshatching the steak not only enhances marinade absorption but creates a beautiful presentation.
- Marinating time: While 4–6 hours is adequate, longer times deepen flavor without overwhelming the beef’s natural taste.
- Meat selection: Choose cuts with minimal connective tissue for the best texture—flank and top round are ideal.
- Resting phase: Essential for maximum juiciness; do not skip this step.
- Slice against the grain: This minimizes chewiness and ensures every bite is tender.
Frequently Asked Questions (FAQs)
Q: Can I use this marinade on other cuts of beef?
A: Yes, “ANT” Kelly’s marinade works well with skirt steak, tri-tip, or even boneless ribeye, although London broil (flank/top round) remains the classic choice.
Q: Can I marinate for longer than 24 hours?
A: It’s not recommended; over-marinating can affect texture and make the steak mushy due to the acids breaking down proteins excessively.
Q: What’s the best way to store leftovers?
A: Store sliced steak in an airtight container in the refrigerator for up to 4 days, or freeze for longer storage. Reheat gently to preserve tenderness.
Q: Is this marinade gluten-free?
A: Replace regular soy sauce with tamari, and ensure Worcestershire is gluten-free for a safe version.
Q: How do I prevent the steak from drying out?
A: Avoid overcooking—medium-rare is ideal. Use a meat thermometer for precision, let the steak rest, and always slice thinly against the grain.

London Broil Marinade Mistakes to Avoid
Common pitfalls and how to prevent them:
