This article explores various methods for preparing a delicious and keto-friendly London broil. Whether you prefer a sweet and spicy dry rub, a flavorful marinade, or a simple slow-cooker approach, you'll find a recipe to suit your taste. London broil, known for being an inexpensive cut of meat, can be transformed into a tender and juicy meal with the right preparation.

What is London Broil?

London broil isn't a specific cut of meat, but rather a method of preparing tougher, more affordable cuts like flank steak or top round. The key to a successful London broil lies in marinating, grilling or broiling, and thinly slicing the meat against the grain.

Method 1: Sweet and Spicy Keto London Broil with Dry Rub

This recipe combines sweet and spicy flavors to elevate a simple cut of meat. The dry rub features a brown sugar sweetener, freshly ground coffee, oregano, coriander, salt, and pepper.

Ingredients:

  • London broil (flank steak, sirloin steak, or top round steak)
  • Olive oil
  • Brown sugar sweetener
  • Freshly ground coffee
  • Oregano
  • Coriander
  • Salt
  • Black pepper

Instructions:

  1. Prepare the Rub: Add the coffee to a small bowl. Then add the brown sugar blend, black pepper, oregano, coriander, and salt. Mix well.
  2. Season the Meat: Place the London broil on a cutting board. Drizzle 1/2 tsp of olive oil on each side of the meat, then rub it all over. Sprinkle the seasoning over the top and rub it all over.
  3. Grill the London Broil: Preheat a grill to high. Grill the London broil to the desired doneness, about 3-5 minutes per side for medium-rare.
  4. Rest and Slice: Tent the meat with foil for 5 minutes, then slice it into thin slices.

Method 2: Grilled Marinated London Broil

This recipe uses a marinade to infuse the meat with garlic and rosemary flavors while tenderizing it.

Ingredients:

  • 2 pounds London broil (top round or flank steak)
  • 1/4 cup dry red wine
  • 4 cloves garlic, crushed
  • 2 tablespoons red wine vinegar (or white wine vinegar or apple cider vinegar)
  • 2 teaspoons gluten-free Worcestershire sauce
  • 1/2 teaspoon dried rosemary
  • 2 teaspoons sea salt
  • 1/4 teaspoon black pepper, freshly ground

Instructions:

  1. Prepare the Marinade: In a glass container or large plastic bag, stir together the wine, garlic, red wine vinegar, Worcestershire sauce, rosemary, sea salt, and black pepper.
  2. Marinate the Meat: Place the meat in the marinade and turn to coat both sides. Cover and refrigerate for 5 hours to overnight, turning once halfway through. A top round steak or flank steak (also known as London Broil) needs about eight hours or overnight to marinate and soften.
  3. Grill the London Broil: Preheat the grill to high. Remove the beef from the marinade, sprinkle lightly with additional salt and pepper if desired. Place the meat on the grill and turn heat to low. Cover grill. Cook meat for 4-7 minutes on first side, then turn and cook the other side for 4-7 minutes.
  4. Rest and Slice: Remove meat from grill and allow to rest on a plate for 10 minutes. Place the meat on a cutting board and slice thinly, being careful to slice diagonally against the grain.

Method 3: Herb Marinated London Broil (Broiler Method)

This recipe uses fresh herbs and a simple marinade for a tender and flavorful London broil cooked under the broiler.

  3. Sprinkle Seasoning: Sprinkle 2 tsp.
  4. Cook: After the time is over, you can optionally leave the top off for the liquid to reduce some more. Serve.

Tips for the Perfect London Broil

  • Marinate: Marinating is crucial for tenderizing and flavoring the meat. A top round steak or flank steak (also known as London Broil) needs about eight hours or overnight to marinate and soften.
  • Doneness: Aim for rare or medium-rare. Overcooking will result in a tough cut of meat. You’ll want to cook it for 3-5 minutes for medium-rare.
  • Slice Against the Grain: This is the most important step for tenderness. If you inspect the meat carefully, you should see that the fibers travel in a certain direction. By thinly cutting the long fibers cross-wise, we create thin pieces of meat with short fibers that are easier to chew and more tender.
  • Rest the Meat: Let the meat rest for 5-10 minutes after cooking to allow the juices to redistribute.

Serving Suggestions

London broil is versatile and can be served with various side dishes. The entire family will love side dishes like sautéed spinach, sweet potatoes, or even a simple side salad. For a special meal, you could pair it with asparagus with lemon sauce from Keto Cooking Wins, Low-Carb Garlic Almond Roasted Green Beans, or Easy Roasted Brussels Sprouts.

Reheating Instructions

The biggest thing to remember when reheating the meat is that you don’t want to overheat the meat. The easiest way to reheat the meat is to heat it low and slow in the oven.
